Jar Jar Binks Costume Modified from a Collectible Statue

Life size prop statues don’t only have to be used for display. If you come across one on clearance or at a thrift sale of some kind, you can disassemble it for parts and use it as a costume. That’s what Kyle Lusignan did for his Jar Jar Binks ensemble. He got the statue from a friend (it’s like this one) and turned it into a wearable costume. He used the clothes from the statue and paired them with Gungan skin from the statue and a mask — he sees through the mouth of the mask. It’s creative, and as you don’t see many Jar Jar costumes, unique.

See a video showing off the costume’s movement at Facebook.

Can empathy enhancing VR really persuade us to care?

Charity water vr 1511307234 C2HK full width inline

Interesting read via Wareable

The new battleground for animal rights is undoubtedly VR. This July, Animal Equality released its third iAnimal virtual reality tour of conditions in dairy farms in Mexico, Germany and Britain. The first video in the series, which many peopel find shocking and disturbing, has had more than 63 million views. Similarly, a new VR video from Australian Beef following meat production from field to fork gets inside an industry notorious for functioning behind closed doors.

The aims of these projects, and ones like them, range from shining a light on awful conditions to trying to persuade regular people to cut down on, or give up, meat entirely.

But is VR more effective than traditional methods like TV spots, celebrity appeals and media focused stunts when it comes to persuasion or just a shiny new tool that campaigners and charities are getting to grips with?

Beyond the fourth wall

Back in 2014, the United Nations commissioned a series of films experienced entirely in VR. The UN Virtual Reality Series sort to push “the bounds of empathy” and reveal the human story behind global crisis, from the Gaza Strip to the victims of Ebola.

One of the films was Clouds Over Sidra, the story of a 12-year-old girl in the Za’atari Refugee Camp in Jordan. A groundbreaking film, when it debuted at a screening for ‘high level’ donors it raised $3.8 billion in one night; it has been translated into 15 languages; UNICEF fundraisers screen the film in over 40 countries; and in New Zealand one in six people that viewed the eight-minute movie donated to the cause, that’s two times more than any other film.

David Cravinho, global funding specialist for UNICEF, has said that on average it will take a fundraiser between ten to thirteen interactions to get someone to sign up to become a regular donor. When VR content is used, that number drops to five or six. It’s no wonder that other organisations and charitable/ ethical causes have followed in the UN’s footsteps. Last year, non-profit Charity: Water, which builds water projects around the globe, held a similar VR-theatre gala in New York and Oculus’ new VR for Good foundation supports various humanitarian programs.

As Patrick Milling-Smith, president of Here Be Dragons, the Hollywood-based VR studio behind the UN series (previously Vrse.works), recently wrote, “You can’t second screen a VR experience.” That alone, though, is not reason enough for this modern wave of successfully persuasive videos.

The age of affinity

Research into the inner workings of charity campaigns that use VR is far from comprehensive. It’s in marketing that the power of virtual reality and its potential for persuasion has ultimately been examined.

Iis Tussyadiah is an assistant professor at the University of Surrey. Her work has explored the digital experience; in particular, the role spatial presence plays in influencing attitude and behaviour to tourist destinations. I asked Tussyadiah what her findings revealed about user experience and how this might relate to a VR experience of a refugee camp, as oppose to a tourist destination.

“For users, VR gives an illusion that they have a first-hand experience in the virtual environment,” she told Wareable. “An illusion of visiting a tourism destination, for example, can lead to an intention to actually visit the place and, I can imagine, if being used in social campaigns, similar effects will be generated.”

Tussyadiah says that through VR, you can ‘transport’ users to a different world. In this context, ‘transported’ is another way of saying that users have the sense of having visited these places. Tussyadiah calls this deep sense of immersion “being there” and argues that it’s a cornerstone of what makes virtual reality so persuasive. “The sense of ‘being’ in a refugee camp, locating the self there, and being immersed in the situation, allows users to imagine how it is to be there and go through what the refugees had to experience,” she told us.

Neodymium Magnet Sphere Circuit Converts 3.7V LiPo to High-Voltage Alternating Current

Spotted over at Public Lab, the full guide is hosted here at Science Toolbar. Definitely not a project for the faint of heart – the sign on the road reads, “Danger! High-Voltage Ahead!”

The rotating magnetic field induces an ac voltage in the stator windings (coil ). The rotor’s magnetic field is produced by the neodymium magnet sphere. The permanent magnet field is constant and the terminal voltage varies directly with the speed of the dc motor. This is an AC electric generator which lights up led bulbs 7 W 230 V. The generator is composed of a coil without core – copper wires, a magnet (neodymium sphere) , a small dc motor, a metal screw pot case, a plastic holder and a battery.

Adafruit Holiday Gift Guide 2017 – Commute with the Adafruit Metro!

Today we’re profiling our own Metro boards – the full-size and ‘mini’ versions. First up the full-size Metro may look somewhat familiar, at least in terms of form-factor-ness:


 
The size and shape of the Metro is derivative of the Arduino UNO R3, with a few of our own bells and whistles thrown in. Notably those 4 indicator LEDs on the edge of the board between the DC power jack and USB receptacle. Also the device can operate at 3.3V or 5V logic with a simple jumper, and the DC jack even includes a micro on/off switch next to it for easily powering down your project when needed without physically disconnecting the power supply.

The full-size Metro is fully compatible with all our Arduino shields as well. (The version shown above has headers pre-soldered to the board, but we sell a header-less version as well.)

To show what that could possibly translate into, here’s an example from Collin Cunningham upgrading a decades-old 2X-L ‘bot with a Metro, Wave shield, and proto shield to accommodate a LM386 amplifier circuit to give his Echo Dot a new look and feel:


 
Next up is also the Metro, but in Mini form factor!

The Metro Mini comes as a fully assembled and tested board, with bootloader burned in and also a stick of 0.1″ header. Some light soldering is required if you’d like to plug it into a breadboard, or you can solder wires or header directly to the breakout pads. Once headers are installed they can be fitted into 0.6″ wide sockets.

Similar in function but in a different size package is the Metro Mini – at only 18mm x 44mm x 4mm the Mini is truly that, while providing all the power and punch you expect out of the ATmega328 brain. The board can easily be configured for plugging into a breadboard, allowing for rapid prototyping prior to designing your own Metro shield or standalone PCB. The small form factor has a unique look, for example in this Metro Minimalist Clock:

A full review of EasyEDA: A circuit EDA online tool

1easyeda

Yahya Tawil wrote in to share his review of a web based EDA tool, the EasyEDA. He explains the general structure of this tool and some of its cool features:

EDA cloud tools which are related to electronics are emerging exponentially in almost all aspects (i.e. simulation, PCB design, footprint creation, gerber files viewing and 3D PCB viewing). Even well-known desktop programs like EAGLE CAD and Altium are trying to compete in this field by making their own services or by acquiring others.
Web-based EDA tool suites like EasyEDA and Upverter are getting rapidly famous. These online tools offer some outstanding solutions for collaboration and providing some viable features for teams with financial limits like multi-layer PCB designing, while it costs a lot to buy a licence for other EDA tool with a multi-layer feature, for example.

The Safety Scarf

The days are getting shorter and shorter my friends. WINTER IS COMING. Night is falling at an unnaturally early hour (in my humble opinion), and I have been finding myself out and about after dark more than during daylight.

alt text

With the LilyPad 10-year anniversary in mind, and a hot set of new LilyPad products, I decided to make myself a winter accessory using sewable electronics that would both keep me warm and keep me safe this winter, all while still looking stylish as heck.

Enter the Safety Scarf (which is more like a cowl, but honestly, calling it what it is would ruin my carefully-crafted alliteration and that's a sacrifice I am not willing to make).

THE SAFETY SCARF:

alt text

The Safety Scarf is a very soft and cozy wearable project that is embedded with a LilyPad UBS Plus, a LilyPad Light Sensor, and two sewable LED ribbons. When ambient light is low, the LED ribbons will automatically turn on, making the wearer more visible to drivers, bikers and other pedestrians - ultimately making them safer. The material quality of the LED ribbon makes them look like piping along the seam - giving them a subtle, clean aesthetic.

As some of our dedicated readers will know from my wearable rants, functionality is just one part of a successful wearable project. I could go on for hours about this, but when designing wearables, it is always important to consider what makes a successful garment as well as what makes a successful functional interactive project. All of this is to say, there is a fun layer of complexity when designing wearable projects that needs to be considered, and because of that, the wearability and versatility of this project are probably my favorite things about it.

alt text

alt text

As shown in the images above, the Safety Scarf features an infinity scarf style. On extra cold nights, the user can loop it around twice, giving extra warmth and comfort. On more temperate nights, the user can wear it loose, allowing more breathing room. Since it is comfy and cute, with the electronics mostly hidden, the user can also turn the scarf off and simply use it for warmth during the day. The circuit switch and charging port are easily accessible too! Does anyone else out there get this excited when form and function meet in such harmony?!

…Seriously. I’d love to know. Please comment below.

To learn more about this project and to make your own, visit the full tutorial here, and, as always, share your thoughts and ideas in the comments below!

Reverse engineering of BK Precision 1696 switching power supply’s LCD protocol

ppreverseengineeringwiring-600

Kerry Wong writes:

As mentioned in my previous post, besides the broken LCD there was also an issue with the power supply portion of the unit and the output voltage was clamped at around 10 to 11V. The digital circuitry portion however seemed to be intact. Unfortunately since an identical LCD is virtually unobtanium, I thought I’d reverse engineer the LCD protocol so once the power supply is fixed I can fix the display by hooking up a different LCD.

Biohacking: Learning to See with Sound

There is a software package that has been available since 1992 called “the vOICe“. It allows for sensory substitution creating an audio landscape based on camera images. The primary application for this software is to assist the blind with navigation. However, I can see from a biohacking perspective that “the vOICe” might just fall under the brushing with magic category.  Arthur C. Clarke’s famous quote comes to mind “Any sufficiently advanced technology is indistinguishable from magic”. Yes, seeing people blind folded that can successful find a table, pick up a fork and serve themselves might just seem like magic to on lookers.

Early home-made setup for The vOICE. Smaller cameras, phones and Raspberry Pi support are making things less awkward.

Here is a summary of the Hardware options to start experimenting with “the vOICe” today:

The above image has a WAV file associated with it so you can hear what the sine wave and block shapes sound like.

Learning the navigation queues:

The good news is that there is an excellent manual with step by step exercises such as picking up blocks on a table while blind folded. The bad news is that this process of hearing where things are needs to be done in baby steps. Just picking up brightly colored blocks from a dark table has a recommended two week training period with 30 minutes a day block practice. Full soundscape navigation fluency is expected to take up to a year.

The voice works in a very predictable way “scans the view from left to right, while associating height with pitch and brightness with loudness. Another way of describing the mapping is that each view is scanned in thin vertical slices, starting with a vertical slice sounding on your left side and ending with a vertical slice sounding on your right side.”

Reading through the manual and attempting to navigate my home with the Droid app required I make some adjustments:

  • Lower the volume – the soundscapes being played are intense and even irritating depending on what is in the current frame. Lower volume helps a lot with absorbing the sounds.
  • Practice Blindfolded
  • Move quickly (when safe to do so) or at least naturally. Moving slow is different experience that has too much thinking involved. The goal is to stop analyzing and become fluent.

Antique grandfather clock retrofitted with Arduino control

When you see a mechanical clock, you know on some level that it took a vast amount of expertise and craftsmanship to get working, but you might also assume that this could all be swapped out very easily with modern electronics. While this might be the case with a clock that only tells time, as David Henshaw shows with his project, once you add in extra features like a moon phase, date indicator, and chimes, things get complicated quickly.

Henshaw began by purchasing an 1847 vintage clock from England without the movement—the parts that actually it tell time. He then replaced the mechanical assembly normally found inside with stepper motors, sensors, an Arduino Uno, and a variety of other wires and bits.

You can see the retrofitted grandfather clock in action below, while the build process (which took the better part of a year) and Arduino code he used are outlined on his website.

Building an 8-step keyboard sequencer with Arduino

Sequencers, as YouTuber “LOOK MUM NO COMPUTER” explains, are musical devices that go through a sequence of tones one by one. While this can be done quite simply with a 4017 counter chip, if you instead substitute in an Arduino board for the counter, you can make your gadget behave normally, go backwards, or even act as a sort of keyboard using input buttons.

This particular project employs a Nano for control, giving it a conveniently small form factor to fit inside your equipment.

Since the start of building modular synths, ive always been looking for an arduino powered sequencer. but never really happy with the projects that were about. because it was still menu dives and button combinations. which is not what you wanna be messing about with! you may aswell use a computer and a mouse ha.

Be sure to check out LOOK MUM NO COMPUTER’s entire build process and a demo of the keyboard sequencer in the video below. You can also find circuit diagrams and Arduino code in the project’s write-up here.

Adafruit Holiday Gift Guide 2017 – Flora, Gemma, and Circuit Playground Classic

All this week we’ll be featuring microcontrollers and development boards as part of our ongoing 2017 Gift Guides!

If you’re looking to get someone interested in a wearables-centric Arduino-compatible platform, Flora is a great place to start. The board is currently in version 3 and is compatible with a smörgåsbord of breakout sensors and modules – including GPS, accelerometer, light sensor, and even a UV index sensor, and more! If you’re curious to see more about those sensors check out the video below and accompanying Flora Sensors Learn Guide for more pictures and descriptions. The Flora book pack is currently out of stock but the standalone book is available so you could still build your own Flora ‘book pack’ for that special someone interested in wearables.


If you’re looking for a wearable solution that’s a bit more discreet, or maybe you only need a few (as in 3) GPIOs, look no further than the Gemma, a small but highly capable device (described in detail – both operationally and with example uses – at this Learn Guide). Measuring only 1″ in diameter, the unit is powered by an ATtiny85 with 8K of flash. Power can be delivered via external battery or USB – and it now even has a micro on/off switch (not shown in following video). Check it out:


Breakout Moment!

Okay so you’re interested in the Flora, but the Gemma is just so darn cute! (And you’ve heard fun things about ATtiny85.) But which one is really for you? Thankfully there’s a video for that! Watch:


OK both the Flora and Gemma look very capable. (Because they are!) But maybe you’re looking for something with just a bit more…zazz! Perhaps a light sensor on-board, oh and a microphone would be swell! And what are the chances of having a small board (I like that round form factor too) with an accelerometer, thermistor, and a bevy of NeoPixels already installed for feedback display or just aesthetics? There’s a board for that! And it looks great too:


 
It’s the Circuit Playground Classic and it contains all the sensors and LEDs previously mentioned and even more! Including pushbuttons, a miniature speaker, and capacitive-capable inputs. At 2″ round, this board packs a punch and is even cheaper than a standard Arduino – WOW!

To give you an example of the touch-and-sound capabilities of the Circuit Playground Classic check out this Star Trek combadge; and to see an example of the feedback from NeoPixels check out this electronic D6 dice project (that uses the accelerometer to detect a ‘roll’).

Make Robot Puppy, Not Robot Enemy: Boston Dynamics’ Latest Robot Dog

via The Verge

Robot maker Boston Dynamics, now owned by Japanese telecom and tech giant SoftBank, just published a short YouTube clip featuring a new, more advanced version of its SpotMini robot. SpotMini, first unveiled in June 2016, started out as a giraffe-looking chore bot that was pretty terrible at performing tasks around the house, and, in one short clip, hilariously ate it on a cluster of banana peels like a character straight out of a slapstick cartoon.

The new SpotMini looks much more polished and less grotesque, like a real-life cross between a Pixar animation and a robot out of a Neill Blomkamp vision of the future, thanks in part to series of bright yellow plates covering its legs and body. The new bot’s movement also looks incredibly fluid. It shows just how much progress Boston Dynamics is making on its goal of life-like, animal-inspired robots that can move and respond to the forces in the real world.

Seen at #MakerFaire: ‘Some Cool Stuff!’ – Specifically a DIY Kaleidoscope – by Randy Sarafan

Instructables Design Studio founder Randy Sarafan had a few projects on display at the recent World Maker Faire. He was showing some of his well-known robotics projects but the one that really caught my eye was his homemade kaleidoscope with a clamping mechanism for holding your cameraphone steady after you position the camera’s lens against the viewing receptacle (shown below) of the kaleidoscope:

A small motor could turn the kaleidoscope, or alternatively you could point it at something which itself is moving (such as images on a screen). The clamping mechanism allows you to record video or take stills of kaleidoscopic images like so:

Economy shipping is now available for international customers

Starting today I am now offering two shipping options for international customers – expedited and economy shipping.

As some folks are no doubt already aware, USPS Priority Mail International costs have more than doubled in the past few years.

Back in 2009 it cost about $12.95 to ship a USPS small flat rate box overseas. As of this year, the cost to ship that same small flat rate box is now over $30!

I’ve received feedback from several customers that the costs to ship overseas were too high, so I started looking at other options and found that USPS First-Class Package International offers slower delivery times (4-6 weeks) but costs less than half as much as USPS Priority Mail. In fact, the current USPS First-Class Package International rates are pretty close to what I was paying for Priority Mail when I first started selling kits. With this new economy shipping option, I can ship a single kit to Canada for $9.50 and to most of the rest of the world for $13.50.

I hope that the economy option appeals to overseas customers who are willing to wait a bit longer to receive their kit. For folks who are more impatient, I am still offering Expedited shipping (via USPS Priority Mail). For super time-critical orders I can also offer Express shipping on a case by case basis (please contact me before placing your order).

Important note: Regardless of shipping method, VAT taxes, duties, import tariffs, customs fees, etc. are always the responsibility of the buyer.

Monolith Synth

Monolith Synth paul Tue, 2017-05-23 12:06

Over the last several weeks I collaborated with Ben Davis, Darcy Neal and Ross Fish on this Monolith Synth interactive sculpture we took to Tested and Maker Faire.

This was a pretty typical usage scene at Maker Faire:

A post shared by Darcy Neal (@drc3p0) on

This crazy adventure started with Kickstarter reached out to me, only 6 weeks before Maker Faire, looking to showcase 4 successful projects in their booth. They wanted to show "creative tools" and how people used them. So I reached out to a few synthesizer folks I've met and who've used Teensy. They also suggested bringing it to Tested to make a video. So it began...

From the beginning I had a step sequencer using illuminated arcade buttons in mind. So I quickly designed this little I/O expander board and sent it off to OSH Park's Super-Swift service.

The whole project came together over just 4 weeks. Our first meetup was just to discuss what to build, followed a week later by our first build night. By then the I/O expander boards had arrived. We made not the final Monolith, but 3 breadboard prototypes, so the software development side could begin!

Another meetup focused only on software. Almost all the software was developed on these prototype panels.

In this picture you can also see the panel layout sketches on the notepad on the right side, and a blue tape model underneath on the table, which we made to get an idea of the overall size.

Ross and Darcy had synthesis plans that needed a signal-controlled PWM waveform and improvements to the envelope feature, so I worked on improvements to the Teensy Audio Library while they wrote the Arduino sketch code.

The day before our next meetup, I started turning those sketches into a design for the laser cutting. I made this 1/4 scale model of the front and side pieces. At this point, none of the back side or interior ribs (for strength) had been designed, and you can see the model lacks the many holes for screws & brackets which joined everything.

Only 2 weeks before Maker Faire we had an epic 13-hour build day where all the final parts were laser cut and assembled. Here's a photo of Darcy & Ben putting the panels together on my kitchen counter!

All the clear acrylic plastic parts were completely drawn, with all mounting holes, and made that day.

Here's the complete layout of all parts (mk2017_design):

Here's a large high-res copy of this image, and a big ZIP file with all the original Corel Draw files for anyone who wishes to try making their own.

While the laser did most fabrication work, other steps like countersinking for the potentiometers were needed. It was indeed an epic 13 hour day of making.

A couple days later, I spent a whole day completing the wiring we couldn't get done in those 13 hours. Erin Murphy (the "Soldering Goddess" at PJRC) put in a few hours on aesthetic improvements to the messy tangle of wires from so many buttons.

Just a few days later we had our last "build" session, to get the 3 separately written Arduino sketches merged and working together as one integrated project. Even though everything has been designed to go together, this session went very late. Ben did much of the heavy lifting to merge the 3 programs.

This is the final audio DSP system settled upon that late night.

Here's a large high-res copy of this image.

This was the first actual usage of the Monolith, well past 1am when we finally had it all up and running.

The next day I took it all apart and packed all the pieces and spare parts into these 2 big boxes, weighing in at 55 and 40 pounds!

This is the first time I've ever shipped a project to Maker Faire, rather than driving a truck or hauling cases of checked baggage on a plane. So much easier, and it allowed time to work on a nice handout card. After some back and forth with the others and last-minute proof reading by Robin, who caught what would have been embarrassing typos and grammatical errors, we sent this card off to be fast-turn printed.


Here is a printable PDF file for the front side.


Here is a printable PDF file for the back side.

Darcy and I flew to San Francisco early and spent the day with Tested, putting it back together while they shot that awesome video. Sometime I hope to have even 1/10th that sort of video production skill.

Since it was already put together, we had little to do setup-wise. Friday morning Ben, Ross and Darcy did some adjustments of the sound levels which really made it come to life in the space. For anyone who wishes to dig deeper into the technical details, thecomplete source code is available on Github.

All weekend long people really enjoyed playing with it. There were many really awesome moments, like this one:

Here is Kickstarter's coverage of the event. Scroll down a bit to the part about Teensy. :)

During the 3 days of Maker Faire, things went very well. We did experience a couple minor issues. Massive electrical noise from so many other projects played havoc with the capacitive touch sensing. Saturday evening I rewrote the code to look for changes from an average rather than just an increase from a threshold, which allowed it to usually work well enough. The other tech issue was a bass. When turned up louder, the bass notes would shake all the plastic panels, rattling screws and even some of the connectors loose at time. Easy to fix.

Towards the end of Sunday, the Maker Faire folks came around and gave up an award. At first I shrugged it off, since they've done the same for other stuff I've brought in prior years. But those were the blue ribbons. Apparently the only hand out one of these red one each in "zone". They said it's a big deal...

Really, the best thing about this year was working with a great team. Ross, Darcy and Ben really stepped up and did a great job on so many parts.

Pictures from the 10th Anniversary ‘OptoSonic Tea’ in NYC

Last week marked the 10th anniversary (wow has it really been 10 years – yes, yes it has) in NYC for OptoSonic Tea – think tea, like steeped, or immersion in, with opto like ocular and sonic like aural envelopes of experience (that said at non-anniversary events conversations usually take place around servings of green tea). Projections and light-based works were more obvious: this image is coming from that lens, with mixing or multi-layered visuals being common. Audio was immersive, and random; speakers were scattered throughout the multi-thousand square foot Pioneer Works in Red Hook, Brooklyn, and sometimes (if not most times) the person you could closest find doing audio mixing wasn’t producing the sounds you were necessarily hearing at any moment. Their sound might be elsewhere, or even delayed.

More than three dozen artists and makers participated, and here are some shots from the celebratory evening:


The main hall of Pioneer Works



Co-organizer Katherine Liberovskaya tends to her mixing station; projection seen above on the architecture of the space.




These rad projectors are housed in unique flip-lid cases; the maker was using analog 35mm slides mixed through some digital software (seen above).


Great sounds from this homemade slide guitar instrument – give a listen:


Old school! The heat coming off this bellows-based projector was intense!



This guy had some sort of kaleidoscopic laser gun – seen on the wall. His left hand went into some sort of ‘pouch’ that somehow controlled elements of the projection:


Stay Puft everyone!


Also here’s a nice timelapse of the work by Chris Jordan that I managed to not get a photo of. However this video shows the work even better than I could have documented and also timelapses the amazing effort artists put into their installations:

‘Bionic Handling Assistant’ by Festo Inspired by Nature | @roboweek #NationalRoboticsWeek #RoboWeek

Festo have been working on some 21st century production robot arms, inspired by nature. Specifically elephant trunks, and fish tail fins. Festo have additional information, videos, and photos of the unit here on their website, and you can watch the video below here on PBS Learning Media where David Pogue gets a unique look at the labs working on this new tech.


 

Learn how one company took inspiration from nature to reinvent the robotic arm in this video excerpted from NOVA: “Making Stuff Wilder.” Host and technology columnist David Pogue meets with engineer Heinrich Frontzek to find out about the Bionic Handling Assistant—a machine modeled after an elephant’s trunk. A traditional robotic arm is rigid and unable to work closely with humans, but this new design is more flexible and less dangerous. The company has also developed a new kind of adaptive gripper, inspired by fish fins, that is flexible and able to securely grasp even fragile objects, like eggs.

Need desk lighting? How about 1,200+ LEDs?

After he’d just finished a project using RGB LEDs, Imgur user nolobot’s brother mentioned he needed a new computer desk. Most people would probably just let their brother buy one, others would make something out of wood, but nolobot instead decided to create something truly amazing using more than 1,200 WS2812 RGB LED modules, an Arduino Mega, aluminum extrusion, and translucent polycarbonate.

The Mega controls these LEDs with the FastLED library, which are sandwiched between a base piece of plywood and a strip of polycarbonate using custom spacers. This diffuses the light nicely, allowing for beautiful light animations directly on the desk’s surface.

You can find more on this awesome build on the project’s Imgur page!

Demo for Slung Load Controller Using #RaspberryPi + naze32 | #piday

After showing what is possible with drone position controlling, Aldo Vargas is back with another drone project, demonstrating compensation for underslung loads. Think of Chinook helicopters transporting Humvees or helicopters carrying sand or water for dousing forest fires. Those maneuvers come with great degree of skill, and learning – operated by humans with years of training, performing moves not typical for commercial drone applications. Which is only to say someone then will figure it out, for drones! The comparison photos, GIF, and video below show what is possible with this controller software.

Multirotor Unmanned Aerial Vehicles (MRUAV) have become an increasingly interesting area of study in the past decade, becoming tools that allow for positive changes in today’s world. Not having an on-board pilot means that the MRUAV must contain advanced on- board autonomous capabilities and operate with varying degrees of autonomy. One of the most common applications for this type of aircraft is the transport of goods. Such applications require low-altitude flights with hovering and vertical take-off and landing (VTOL) capabilities.

Similar as before in this project we use the AltaX Flight Stack which is compromised by a Raspberry Pi 3 as companion computer and a naze32 as flight controller.

The slung load controller and the machine learning estimator is running on the RPI3, although of course the training of the recurrent neural network was done offline in a big desktop computer. The RPI calculates the next vehicle position based on the estimation of the position of the slung load, everything is running using our framework DronePilot and guess what? its open source ;). Keep reading for more details.

The results? Pretty remarkable. Here’s a side-by-side comparison of an underslung loaded drone without and with the controller running:

And here are timelapse photos showing the drone without the load controller:

And here’s that same load while compensated using the load controller:

Wow! That is a difference!

Vargas walks through the setup in the video below, and you can read a bit more here on his blog:

‘Variant: Limits’ is Like Myst for Calculus Students – Explore a 3D World, Solve Puzzles with Calculus! | @Triseum

This. Looks. Amazing!

Triseum have announced a “third-person exploration game based on calculus” called Variant. While the gameplay is clearly different from Myst (3rd person perspective, rotational 3D world), the trailer (below) does remind me of moments from that breakthrough game, solving puzzles to advance through a curious world – how did this architecture get here? Who built this place? Who maintains these grounds? And yeah, you get to learn calculus along the way!

 
Watch the complete trailer:

Triseum are accepting applications from “selected institutions and educators” for “a sponsored pilot in spring 2017 to bring the ultimate in game-based learning experiences to your calculus students.” If you’re interested you can read more and apply for the pilot here – and I do hope this gets released to the general public, and I’m sure I’m not the only one interested in re-learning calculus knowledge through immersive gameplay!

Little Tike Cozy Coupe Upgraded with Arduino Uno, Wave Shield for Custom Sound Interactions

Brentmore Labs took to upgrading his BMW-hooded Little Tike Cozy Coupe with some custom electronics, adding sound effects and replacing some elements along the way and even doing some custom 3D-printing where replacing plastic parts was required. In short, AMAZING! Check out the video below to hear one of the sound effects, and read more about – including looking at the code running this project – here.

The Little Tike Cozy Coupe, a children’s classic made of soft hollow plastic (LPDE), is a blank canvas for tinkering and customization. While the car comes with some entertainment options, such a squeaker in the horn, I think that my client deserves something a little more realistic and, of course, high-tech.

This wasn’t a particularly difficult project, but it did take a bit of time to set up. The overall concept is to create a media controller which plays different sounds depending on the button pressed. I figured I could replace the toy key with a giant button and also fill the blank space on the left with some buttons to select the music.

Enginursday: Voltage Regulator Temperature Mobile App

When a design needs an inexpensive, simple and low-ripple voltage supply, a great choice is a linear regulator. These benefits come mostly at the cost of efficiency, which is lost in the form of heat. How does one know if a simple linear regulator can safely operate in a system, how much power is wasted, or how much heat needs to be managed? We’ve created a simple tool that calculates this information for you.

Model of a Linear Voltage Regulator

High level model of linear regulator

Figure 1: High-level model of linear regulator

Figure 1 shows a high-level model of a linear regulator. It consists of a resistive pass element that is controlled by some logic to keep the output voltage at the desired value. At this level only three values are really needed to feed the model and get values for power lost and heat generated: the input supply voltage, the desired output voltage and the current being drawn by the load. That’s all that is required to determine values to necessary precision.

In reality, the pass element isn’t normally a potentiometer as shown, and the control logic is more than a magic box.

More Detailed Conceptual Model

Figure 2: More detailed conceptual model (Courtesy of Linear Technology)

A possible actual implementation uses an error amplifier to sense the output voltage of a voltage divider. The error is the difference between the scaled voltage and a precision reference. The error feeds the base of a bipolar or gate of a field effect transistor in their linear regions. The current through the divider and into the amplifier is known and can be accounted for.

The model used by this application assumes that the power used by the control logic is negligible. In reality, I’ve seen values as low as 1.5µA. Other regulators use on the order of 10’s of µAs. A low quiescent current of 10µA is only 1 percent error when drawing a single mA. Typical use cases are often in the multiple mA range and up. Since the power used by the logic is negligible, the current in is equal to the current out and only needs to be set once. The extra voltage is lost in the form of heat in the power transistor.

Regulator Specifications

The app comes with some typical values for a generic linear regulator already set. This is great for playing around and estimating, but for real applications the actual manufacturer specifications should be used. These may be tricky to find, but the best place to look is in the manufacturer’s datasheet for the part.

Example regulator specifications

Figure 3: Example regulator specifications from datasheet (Courtesy of Maxim Integrated)

The key specs to look for are the maximum junction temperature and the thermal resistance. The resistance varies from package to package and the thermal mass of whatever the regulator is touching. For this example we will take a common use case of a regulator without forced cooling and without a heat sink attached to a four-layer PCB. The datasheet shows this thermal resistance (θJA) between the junction to ambient to be 42°CW.

There are at least three values listed for maximum temperature. The part is rated to operate over the -40°C to +125°C automotive temperature range. That’s not relevant to this math. The maximum junction temperature is spec’d to be +150°C. We can verify that this is a good value since later in the datasheet it is stated that the device will go into thermal shutdown at +165°C. That’s a state to definitely avoid, so there is a little margin.

Using the Application

Example regulator specifications set

Figure 4: Setting example specs

Maximum current allowed example

Figure 5: Determining maximum current allowed

At the top of the app is the familiar hamburger menu that slides the settings out from the left side. Figure 4 shows the thermal resistance of 42°CW and the max junction temperature of +150°C entered. This example uses the default ambient temperature of +25°C. Swiping the settings back to the left hides them. The input voltage was arbitrarily chosen to be 12V, and the output to be 5V. The current slider was wiggled until it was right around the point where JUNCTION TEMP: XY.Z°C label turned red (@ 150°C) and fine-tuned with the steppers to the maximum point where the label wasn’t red. This turns out to be 0.425A, which is wasting nearly 3W of power.

Tips

If you live in ‘Murica you are probably more comfortable with temperature units of degrees Fahrenheit. There is a setting to change the units to °F. Touch the gray Fahrenheit (°F) label. It should turn green, indicating the change has been made. Only the thermal resistance will remain in the units most of the world use (°CW) since we aren’t sure where to find those values in other units (°F·sft·lbf?).

The default ranges of the sliders cover a fairly large range that should work for many cases. If the parameters for a project are outside of these ranges, then the bottom section of the settings is provided as a way to fix that. There might be cases where one wants a clean 200A supply of 24V. Feeding up to ~24.021739V into a magic LDO, that range can be set. Many designs may lie in a narrow range. The parameter ranges can be tightened up to make finer tuning easier. The range of the slider is discretized because there are only so many pixels on a screen. If a value cannot be set with the slider, narrow the range or use the steppers next to the sliders to fine-tune the value.

For back-of-the-envelope type calculations, wiggle the slider near the desired value. If nothing turns red, then the application is nice and safe.

Advanced Use and Hacks

The first hack allows typing in the desired voltages and/or current to great precision. The trick is to set the desired value as the min or max for a slider setting. After that, simply swipe all the way to that extreme, and the exact value is set.

Example regulator specifications set

Figure 6: Setting exact values as slider extremes

Maximum current allowed example

Figure 7: Using those typed-in values

The precision of the inputs on the UI is limited to 10mV and 1mA steps, but the math isn’t. To come up with eight significant digits in the last section, a minute or two was spent using this hack to get that value (which is likely poor using only a simple linear model with the used assumptions).

alt text

Figure 8: Excessive precision

Another ‘hack’ is too use ‘fake’ values for the thermal resistance to model heat sinks and other configurations. Sum the thermal resistances of the regulator, the junction between it and a heat sink, and that of the heat sink.

Adafruit Holiday Gift Guide 2016: BeagleBone Black Products & Projects

unnamed

The BeagleBone Black is a lil’ Linux-powered single-board computer whose curved corners allow it to fit snugly inside a mint tin 😉 The ‘Bone has a capable array of GPIOs, PWMs, analog inputs, along with I2C, SPI, and the highly-reliable low-latency PRUs (Programmable Real-time Units, powered by two 32-bit 200MHz built-in microcontrollers!), among other features and capabilities. Below we’ve rounded up everything from getting started with to peripherals to some projects that use the ‘Bone:


The Essentials

5V 2A (2000mA) switching power supply – UL Listed

276-00

OK first things first and with the BeagleBone Black that means a dedicated power supply. This wall wart supply of 2000mAh is sufficient if not ideal. Long-story short you don’t want to power the BeagleBone Black over USB if you plan on conducting any WiFi activity (see adapter, below) or driving any project where the power draw might spike. Get a good power supply, and you’ll be good too! This wart is relatively small for the punch it packs with plugs in the orientation I prefer for most of my project installs.


USB WiFi (802.11b/g/n) Module with Antenna

1030-03

Not as discreet as other WiFi modules on the market – but personally I dig the articulating antenna that I can somewhat point in the optimal direction (and yes things like this do actually matter, like, a lot) for my installation.


From Prototype to Project

Adafruit Proto Plate for Beagle Bone & Beagle Bone Black

702-00

For any board, you’ll likely want to begin with a breadboard setup, and proto plates are not only a great way to house a breadboard alongside whatever board you’re working with but allow easy pickup-and-go transport of the prototyping to any new location.


Adafruit Proto Cape Kit for Beagle Bone & Beagle Bone Black

572-00

When you’re ready to make your prototyping layout a little more permanent – and perhaps reclaim your breadboard – consider migrating everything to this Beagle Bone Proto. It doesn’t contain as much prototyping real estate as a breadboard, and will require a nominal amount of soldering, but it looks great and will make nice and tidy your custom through-hole component circuit for your BeagleBone Black.


Anidees BeagleBoneBlack Case – Silver Aluminum with Crystal Top

2628-00

And when you’re ready to go full-enclosure, for install either at your workstation or in an environment where the ‘Bone can be placed and left alone, this aluminum-finished enclosure looks fantastic. There’s room inside to house your Beagle Bone Proto as well – although not necessarily the components on top, that all depends on your design and layout. The clear top allows easy viewing of the board or any display or indicator LEDs you might have installed.

And of course if you like this sleek case but want it a bit more stealth-looking, check out this black version. 😉


Projects

Blinking an LED with BeagleBone Black

‘LED blink’ is basically the ‘hello world‘ of any single-board computer project – and this 15-minute project will have you going ‘Aha!’ when you’re done with how easy and intuitive the ‘Bone can be. After this you’ll no doubt want to explore other simple how-tos like measuring temperature or measuring light values – then you’ll be ready for more sophisticated motor control or capsense projects.


LedGames – a BeagleBone Black 64×64 LED Game

Not exactly a simple project, this build will test your fabrication, soldering, and software skillz. But the result is a fantastic-looking 64×64 retro gaming station LedGames!


Dirty Dish Detector

 
My own little claim to fame is this ‘Bone- and OpenCV-powered project I built alongside Jason Kridner called the Dirty Dish Detector. The hardware is relatively plug-n-play, however it will involve some navigation of the command line, as well as Cloud9 which is a brilliant built-in cloud development solution for ‘Bone builds!

Does your makerspace have a sink that is always full of dirty dishes? Or do you yourself require better discipline around the home to stay on top of your chores? To automate your home, office, or workshop, one of the first things you’ll require is some kind of vision system to detect motion or objects. A small computer capable of running OpenCV could be just the tool you need.

The Dirty Dish Detector combines a BeagleBone Black & Logitech webcam – along with plenty of open-source software – to tackle the annoying activity of tracking when dishes get left in the sink.

‘Zooids’ are Open-Source, Open-Hardware ‘Bots for ‘Swarm User Interfaces’

I admit, they’re cute. But I can’t help but think this is the beginning of the creation of those swarm bots that derail the path of Destiny in Stargate: Universe; I’m strictly talking in parallel-universe dimensionality of course, because we all know those drone-bots are not currently anywhere near our solar system – let’s keep it that way okay!

This paper introduces swarm user interfaces, a new class of human-computer interfaces comprised of many autonomous robots that handle both display and interaction. We describe the design of Zooids, an open-source open-hardware platform for developing tabletop swarm interfaces. The platform consists of a collection of custom-designed wheeled micro robots each 2.6 cm in diameter, a radio base-station, a high-speed DLP structured light projector for optical tracking, and a software framework for application development and control. We illustrate the potential of tabletop swarm user interfaces through a set of application scenarios developed with Zooids, and discuss general design considerations unique to swarm user interfaces.

Father Turns Son into a Transforming Optimus Prime

It’s apparently the year for especially fantastic homemade Halloween costumes. We’ve seen one parent craft a cute and furry tauntaun costume for their toddler, and now Redditor Renz2LK has made an Optimus Prime costume for his son. It’s not just any Optimus Prime cosplay — it actually transforms. I’m mesmerized by the above video.

Renz2LK spend about six hours over two days crafting the Optimus Prime costume. He used scrap EVA foam from his workshop to build the vehicle shell. He painted it using spray paint and added acrylics for weathering. Regarding using EVA foam, he said:

As for my son’s costume, it was basic geometric shapes, so it was pretty easy to just custom size each piece to fit him. As for the transforming part, I had seen him pretending to transform while playing in costume. I just created the cab portion of the truck to cover him and found that it was easy to flip it open when he stood up.

And another look at the transforming action:

‘The Jolly Julep,’ Handmade and Hand-Powered Paddle Boat #WMF16

‘The Jolly Julep’ was a fun handmade paddle boat designed by The Fulton Mules, on display at World Maker Faire this past weekend. It uses a simple slide mechanism to translate human push-power into spinning paddle speed (see video below!). And as things go in NYC you can’t exactly park this in your apartment (some apartments are smaller than this boat!), so the whole thing was designed to quickly break down and re-assemble; the team built it the day before in a few hours (in the rain no less!). The boat was a recent participant at the Battle for Mau Mau Island, itself a project of some of the Swimming Cities crew, who I wrangled many years ago to display their fish-boat at the inaugural 2010 World Maker Faire – so it was good to see boat culture alive and well at a Maker Faire!

‘MindTIME’ will Make You Question Your Perception of the Passage of Time #WMF16

‘MindTIME V2’ was a fun interactive sculpture made by Kritwalee Seneetantikul, seen at World Maker Faire this past weekend. Consisting of three panels of multiple spinning dials, users would initiate their spinning by touching a conductive pad on the table; the stepper motor-controlled dials would then spin for an unknown amount of time. The challenge to the user was to guess how long the dials spun. Do more dials make more time appear to go by? Do fewer dials slow down our perception of time when in fact more goes by? Users could fill out a survey card of sorts, then compare their answer/s.

The frames were really well designed and the stepper motors mounted nicely on the back:

MindTime is a series of interactive sculptures that encourage participants to explore their own perception of time. The installation consists of three sculpture sets, each running a different speed. The visitor is encouraged to concentrate on each sculpture and predict how much time has passed. This is analogous to our own lives where time passes too quickly when there are many tasks to complete but moves too slowly when we are waiting for something or seemingly have nothing to do. The experience for each visitor will vary, being either fast or slow according to the way the individual perceives time. I invite visitors to share their results in this paper and compare their different time perception experiences with each other.

Seen at World #MakerFaire: Play ‘Currency,’ a Bitcoin-Based ASCII Game Hacked into a Burroughs Adding Machine

A game that constantly fluctuates with the current market value of Bitcoin – thus the ethernet shield attached to the Arduino core, constantly checking the value of the cryptocurrency:

This kid was not only really into the game – obviously! – but went on to win it with about 30 more lever pulls!


 
img_20161001_123404

With the rise in prominence of the crypto-currency Bitcoin financial markets and governments are scrambling to see how to adjust to this new insurgent monetary form. As an insurgent, Bitcoin becomes the foil in an ASCII generated 8 BIT game who’s controller is a hacked Burrough’s adding machine with receipt printer as the play field. Mirroring the mechanics of 8 BIT Atari games like Defenders or Caverns of Mars the game scrapes data off a Bitcoin trading site to control speed and difficulty of game play. Players attempt to pull the two columns of ASCII symbols together while either being aided or impeded by the current exchange rate of Bitcoins to U.S. Dollars. Because of the twenty four hour nature of this unofficial market each time a player enters the game world scraped data will be different making for new game play, changes may be subtle minute to minute or drastic depending on the fluctuation that day. The Burroughs machine with its intricate mechanisms give the player a tactile portal into the complex systems that control the movement of Bitcoin’s through the web. The printed field, referencing ticker tape of the early stock exchange, this also give the player a record of their game play allowing them to collect and share their success or failures. Players navigate and are faced with the complicated quandaries and pitfalls that come with an unregulated non-central monetary system and the obvious questions this kind of economic system raises. The risk reward of competing in this volatile market is reflected in the risk reward of the game where players can see if luck will be on their side.

‘Megachordotron’ is a Simple MIDI Controller Built with Teensy, First Seen at World #MakerFaire #WMF16

Will Ware (actual last name!) built this … ware, a MIDI controller assembled around a simple wood-and-hardware interface, using Teensy 3.1 or 3.2, “organized around chords, designed for people too clumsy to play a guitar.” And it sounds pretty cool too!

 
And the best part is the project’s build notes are completely open-sourced and available here on GitHub!

Diving into the Homestead Crater Wearing a Glowing SCUBA Suit #Utah #WearableWednesday

This is cool. Recently the bridge over the Homestead Crater in Utah was removed and some swimmers were allowed to dive into it, including a member of the USA Cliff Diving team who donned a glowing (likely EL wire, although the article calls it an “LED light suit.”). And thanks to Elizabeth for sending this in!

On a dark night, four people recently dove from a height of five stories into Midway’s Homestead Crater.

One of the divers was Andy Jones, a member of the USA Cliff Diving team who is on the Red Bull cliff diving circuit and grew up in Sandy. He donned an LED light suit for the event, which was hosted by Nu Skin.

Pictures from the Red Hook Regatta in Brooklyn of DIY & 3D-Printed RC Boats @PioneerWorks_

Yesterday was a beautiful day throughout the five boroughs of New York City, and an especially great day for navigating DIY and 3D-printed radio-controlled boats on the Red Hook Channel in the Upper New York Bay! The 2nd annual Red Hook Regatta is an initiative of Pioneer Works, a nearby non-profit arts center and event space. The Regatta supplies makers with some components and parts to assemble a DIY or 3D-printed boat, to be radio-controlled from the beach while attempting to deliver ‘cargo’ in the form of foam blocks to nearby piers. The distance from the shore to the piers was quite far consider the scale of the boats (less than 2′ in length). Any boat that ran aground or died in the water was retrieved by a human in a kayak.

Boats were divided into two camps: DIY & 3D-printed; the latter is obvious and the former were basically anything goes, including a toy converted into a vessel, a mostly-foam (I think) boat, and even a ‘trash boat’ that consisted of trash vacuum-sealed in some sort of container (it didn’t last long!). The event mostly consisted of 3D-printed boats, some of which can be seen below.

Shoutout: Adafruit’s own Dano Wall (with our fabrication department) who competed with his 3D-printed boat Infinity Wake! (see photo below)

Pheromone und wie sie funktionieren

Der Duft der Liebe, Lust und Leidenschaft bringt Kochen? Nicht zu beleuchten die neuesten Düfte Tests, aber die Forschung auf dem Gebiet der Pheromone. Dating Diese biochemische Botenstoffe unseres Körpers einen wesentlichen Einfluss haben, und wir können es riechen, und wer nicht – und wie wir sexuell zu jemandem hingezogen fühlen. Pheromone, chemische Botenstoffe im Körper: Die letzten Geheimnisse der schlechten Gerüche sind ein Forscher auf der Strecke. Werbeforschung, die Auswirkungen der unterschwellige Wahrnehmung ist so sehr kurz auf dem Bildschirm bekannt unterschwellige Werbebotschaften. Obwohl wir nicht bewusst wahrgenommen haben, ist es immer noch gearbeitet, und ohne die wir uns gegen zu verteidigen. einen Partner zu finden und Sex zwischen Männern und Frauen, stark die Wirkung von Pheromonen.

Pheromone, geheimen Verführer

Die Menschen schwitzen, Talgdrüsen und die meisten Geruch. Diese sind nichts anderes als für uns einen charakteristischen Körpergeruch zu haben. Aber was sollen wir tun? Jeden Morgen unsere eigenen Duft Duschgels und Shampoos wir decken. Hier, wie viel über die Ursache des Geruchs kann sowohl positiv als auch negativ sein. Die sogenannten Pheromone, die von Männern und Frauen chemische Botenstoffe ausgeschieden werden. Es sind organische Moleküle, instinktive Kommunikation zwischen evolutionär als ein Lebewesen dienen. Das ist einige unserer anderen und umgekehrt sind verantwortlich für die Verursachung Pheromone, in der Regel aus der Achselschweiß oder auseinander fallen und die Oberlippe der Scheide bei Frauen, bei Männern. Sie wird direkt an das limbische System durch Riechschleimhaut umgeleitet, die, wie Hunger, Müdigkeit, Sexualität und instinktiven Gefühle vieler Kontrollen in das Gehirn verantwortlich ist. So Pheromone, Herzfrequenz und Atemfrequenz, und die Wirkung der Fortpflanzungsorgane, wo sie den Sexualtrieb, die Wirkung bestimmter Körperfunktionen stimulieren. von “””” Geruch “””” Heute kommt der Begriff aus der Erfahrung. Paare, die jeder gut, extreme Geruchs Situationen riechen kann, wie zum Beispiel nach dem Training oder der Menstruation in den Tagen, und nicht unangenehm, aber sie sind: Der liebe Mann Holz zu arbeiten, klicken Sie lieber attraktiv und seine Lust geblasen Sex und Parfüm keine Anziehung kommt hacken es zu diesem Zeitpunkt ihrer Pheromone sein kann, zu erhöhen! Also, ein Mann, vor allem ein Sport mit anderen Männern Schweiß Pheromone wie im Wettbewerb, die aggressiver sind, weil sie konfrontiert sind, nicht aber in der Regel das Gegenteil – auch ist interessant, die Art und Weise, dass Pheromone wirken auch in der gleichen Gattung. Auch kann eine Körpergeruch einer Frau und Beduftung die weibliche Konkurrenz Bote mit darin enthaltenen Stoffen. Pheromone können ein echter Frauenmagnet sein.

Was sind die sexuellen Boten zu uns?

Wissenschaft macht eine kurze Reise clever: Pheromone sind Vererbung und Wiederherstellung des Immunsystems des Individuums besteht aus verschiedenen Infektionskrankheiten. Jetzt das Immunsystem sind unterschiedlich zwischen Männern und Frauen ausgeprägt ist “”,”” besser “”,”” die genetische Sicht diese Kombination für ein Kind. Deshalb ist das Paar miteinander zu begleichen gut, bieten kann “””” gut riechen “”,”” nicht unbedeutend, auch die fantastischen Sex, oft sogar. Die Zusammensetzung der Pheromone einzelnen Heulen schlägt vor, wie Fremdgerüche auf der Oberfläche der kontraproduktiv: sie Glanz ihren eigenen Geruch über, und mit ihm wird eine genetisch und daher sexuell – “””” die “””” halten Partner. Die Dosis macht hier: Wer glaubt, dass auch nach 8 Stunden Sport, ungeduscht sexy Duft, es ist falsch. Und die wirklich schlechten Geruch Schweiß, Schweiß, Bakterien zu zersetzen beginnen, der Geruch der Chancen, weil sie mit einem Null-betören. Situationen extremer externen natürlichen Duft, versprach jedoch eine “””” normal “””” Körperpflege zu überschreiben, nicht zu setzen. Somit wird ein Schweiß “”,”” rechts “”,”” Partner für die richtige Dosis zu attraktiven riechen.

Auf jeden Fall sollte man nicht blind glauben, dass die Werbebotschaften der Industrie. Werbeaussagen wie: “””” Nehmen Sie diese Salbe und Rennen Frauen zu Füßen liegen, “”””, sind mehr in Frage gestellt, weil er in der Regel schnell ist nach hinten los. Zunächst einmal riechen viele dieser Düfte oft “””” Apotheke typischen “””” durch – und das ist nicht viel exotischer Reiz auszusetzen. Zweitens Zogen Betäubungsmittel Duftmarken beinhaltet Risiko von Verlust der Glaubwürdigkeit. Der Träger “””” Person “””” ist, einfach, nicht lokalisiert länger an der Nase der anderen Person. Jeder Duft als exotisch, kann teuer sein, oder einzeln, er komponiert, hat aber immer noch einen gravierenden Nachteil: Ob Mann oder Frau, es ist der Geruch von Parfüm Ganzen. Das ist manchmal auch wünschenswert: ein kleiner Sprint aus dem Auto Für viele Bäckerei Fahrt von den Poren der Achselschweiß schon (das Auto in der Reihe 2 geparkt ist) – und nicht nur riecht nicht gut. Hier Deo Güte ermöglicht modernen Kosmetik Duft trotz des hektischen Lebens. Und in der Tat, dass ein paar glückliche Frauen: Hat der Mann versehentlich. rechts “””” vor Superlovers 2 Jahre riechen, war er an der Vorderseite des Smell-Plagiator. Aber wer will schon als Ergebnis der anderen erfolgreich zu sein? hat “”,”” Matching “””” Geduld, Experimente und Mut, um schließlich den Geruch des Duft Sie selbst finden wollen stehen. Sie sind weniger wahrscheinlich häufig verwenden, wie Sie Parfüm mögen. Der Trick besteht darin, darauf zu bestehen, dass ihre eigenen Geruch, der Geruch ihres Körpers mit seinen vielen attraktiven Pheromone einen Duft zu finden! Und das Beste, was über diese faszinierende Aroma, seine Individualität -. Als ein bestimmter Geruch ist persönlicher
