Monday, February 24, 2014 - 21:00Light Up Thor Costume
Superheroes seen in comic books often have unrealistic proportions. Women are given big chests, and men get giant muscles. Though it’s not necessary to match a character’s physique when you cosplay, you can add bulk if you want to. Instructables user spiderball built a Thor costume for Halloween, and he used craft foam to build up his arms to Norse-god like proportions:
I wanted my arms to have a bit more size so with the 1/8th [inch] craft foam I cut segments to create the muscle groups of the arm. These groups were then hot glued together giving me a fake arm which started at the top of my shoulder down to the wrist.
This was trial and error to get the size and shape you want. I started with a bicep to get the scale for the rest of the arm. The first picture is of the shoulder, I placed it over my actual shoulder and moved around to make sure I had enough room. The next picture is from the shoulder to elbow, once again I slipped it on to make sure it was to scale and I could move in it.
Once both arms were constructed I coated them in contact cement and then placed on a layer of cheese cloth. This gives strength to the seams to prevent tearing. Next I cut out 3/4″ squares and covered the arms from shoulder to mid forearm, the squares are craft foam and hot glued on.

Monday, February 24, 2014 - 21:00Cosplay Interview with Sarcasm-hime
Besides being amazed by the resourcefulness and maker skills cosplayers possess, I’m often impressed with how helpful they are. Many people who make and create are willing to pass on knowledge or answer a question, and cosplayer Sarcasm-hime (featured on Adafruit here) does so through several tutorials on her website. She’s created several costumes ranging from the Scarlet Witch to Arwen to Death and learned all kinds of skills along the way. It’s easy to lose track of time while browsing her site to look and costumes and her tips and tricks.
We talked with Sarcasm-hime about what inspired her to cosplay, why it’s important for her to share knowledge, and more.
Adafruit: You have a dazzling array of costumes. How long have you been cosplaying and what inspired you to start?
Sarcasm-hime: I’ve been cosplaying since 1999; I was interested in sewing and costuming before that but I didn’t find out about fandom and cons until ’97, at which point my head exploded in a “HOW DID I NOT KNOW ABOUT THIS MAGICAL THING” kind of way and I never looked back. Having an excuse to make fancy things and play dress-up multiple times a year (while hanging out with other nerds in fancy clothes) is pretty much my idea of heaven.
I started for the same reasons that most cosplayers do – it’s fun to dress up as your favourite characters. That said, there’s a saying “There are two kinds of cosplayers – anime fans who like to wear costumes, and costumers who like anime.” I’m definitely one of the latter, as for me a huge part of the appeal for cosplay is the creative process, the problem-solving, learning new things and the feeling of accomplishment at completing something difficult/time-consuming.
Adafruit: I noticed your site contains a section with several tutorials. How-tos take time to create; why is it important for you to share your knowledge with other cosplayers?
Sarcasm-hime: When I started cosplaying there weren’t a lot of tutorials available. These days you can find a tutorial for pretty much anything quite easily, but back before YouTube it was really hard to find any resources or helpful instructions for cosplay. Others helped me out when I was first starting, and I felt it was really important to ‘pay it forward’ and share what I learned with others. My tutorials are pretty basic compared to a lot of the stuff out there now, but I still do get emails from time to time thanking me for them, which gives me massive warm fuzzies.
This is one reason I love Costume-Con so much; it’s a con devoted entirely to sharing costuming techniques, and it’s full of costume nerds like me who love to ogle each other’s crazy obsessive details. There’s always something new to learn.

Adafruit: What new skills have you acquired over the years of cosplaying?
Sarcasm-hime: I’ve learned a lot, mostly by trial and error (see above comment about lack of tutorials). I knew basic sewing when I started, but since then I’ve learned draping, embroidery, beading, woodworking, prosthetic makeup, corsetry, metal casting, mascot construction, wig styling and (very) basic electronics, among others. For me half the fun of cosplaying is figuring out how to bring a 2-D design to life, so I try to always choose something that will challenge me in some way.
Sadly, one of the skills I still haven’t acquired is the ability to come up with a really funny and/or awesome skit. I decide to make a costume because it looks awesome and/or I relish the challenge of making it, and then at some point a week or two before the con I have to come up with something to do onstage, which usually ends up being ‘swan about the stage showing off my pretty dress’. Fortunately I have awesome friends to help out with the skit ideas.
Adafruit: Which costume so far has presented the biggest challenge and why?
Sarcasm-hime: That would probably be a costume that I’m still working on now – Garuda from Final Fantasy XI. I chose the design because it involves techniques that I haven’t used before (making giant wings with a harness, digitigrade legs), and has proven to be quite daunting. I’m hoping to get it done sometime this summer.
Besides that, though, it would probably be Moondragon; I hadn’t worked with Worbla or electronics before, and the method I came up with for attaching the wings and the spine turned out to be trickier than anticipated. For most of my costumes I plan out early how I’m going to do pretty much everything; it just often involves months of fiddly detail work (if that counts as a challenge?).
Adafruit: What advice would you offer to people who want to try cosplaying for the first time?
Sarcasm-hime: Firstly, choose a costume that’s going to make you happy; ideally happy making it and happy wearing it.
Secondly, when starting out I advise choosing a design that fits your skills. Evaluate what you think you can manage and how much time you have, and then pick something that is feasible. Don’t bite off too much right at the start, especially before you have a sense for how long it will take you to make things. Rushing to finish costumes while AT the con and not getting any sleep sucks and is no fun. I’ve done it too many times and swore never again!
There are tons of tutorials out there now, so search for tips and instructions. That said, a big part of the fun of cosplay is problem-solving. If you can’t find a tutorial that matches exactly what you’re aiming to do, experiment!
I have more advice on my site.

Monday, February 24, 2014 - 20:00Stretchable optical circuits could find use in robot skin and more
More on the future of flexible electronics from gizmag.
If flexible electronic devices are ever going to become practical for real-world use, the circuitry incorporated into them will have to be tough and resilient. We’re already seeing progress in that direction, including electrical wires that can still carry a current while being stretched. However, what if the application calls for the use of fiber optics? Well, scientists from Belgium may have that covered, too. They’ve created optical circuits utilizing what they believe are the world’s first stretchable optical interconnections.
The idea is that devices such as wearable sensors or touch-enabled robot skin could utilize standard glass fiber optic cables for the most part, but could use the interconnections to bridge gaps between those cables, allowing the device to bend or lengthen at those locations.
Made from a clear rubbery substance known as PDMS (poly-dimethylsiloxane), the interconnections feature a transparent core through which the light travels, that’s surrounded by an outer layer of the same material. Because light doesn’t move as easily through that outer layer due to its lower refractive index, the design keeps the light signals contained within the core.
In lab tests, the interconnections were able to guide light signals when stretched by up to 30 percent, or when bent around an object with a diameter as small as that of a human finger. What’s more, they maintained that functionality after being mechanically stretched by 10 percent a total of 80,000 times.
Monday, February 24, 2014 - 19:01Guest Post: Try Radar for Your Next Project
Sensors. The low-end stuff that we can get our hands on usually suffers from poor range, lack of sensitivity, and no way to characterize what the target is. But today we can use the good stuff that, until recently, was only available to military: radar. In this post we will discuss how radar works, commercially available small radar devices, and where to learn more to help make it easy to add radar to your next project. Reach out and sense something!
Radar is simple, it consists of a radio transmitter and receiver. Radar is a World War Two acronym meaning Radio Direction and Ranging, in other words a radar consists of a radio transmitter and receiver where the range to an object is measured by clocking the time between the transmitter transmitting a known modulated waveform and the receiver receiving this waveform scattered from a target.
One enabling technology for Radar was the cathode ray tube (CRT), which facilitated a method of measuring the time delay between transmitted and received waveforms. This led to the development of numerous radar sensors used in the second world war, which generally followed the Plan Position Indicator (PPI) architecture.
Toady, rather than using a CRT we can use high-speed digitizers. This offers the obvious advantage of applying signal processing to acquired data so that only moving targets are detected, tracking can be achieved, imaging, and a multitude of other modes.
But for hobbyist and consumer projects we do not need this much power, range, and can not afford the cost. We need the ability to sense like a long range radar (detecting only moving targets, imaging, Doppler, signatures, etc) but at short ranges and at low costs.
Very few off-shelf small radar options exist as of today. In this post we’ll review these, their basic architectures, and direct you on the next steps.
Continuous Wave (CW) Doppler Radar
If you are not interested in ranging or imaging but would like to measure velocities or radar signatures then consider CW Doppler radar. CW Doppler radar works by feeding the output of a CW oscillator to an antenna and radiates that carrier towards a moving target. This carrier scatters off the moving target back to the receive antenna where it is amplified and fed to a frequency mixer. The mixer mixes the oscillator and the scattered carrier resulting in a Doppler shift product. This product is the Doppler shift off of the carrier’s center frequency and is generally in the KHz range. Low enough to be easily digitized by the audio input port of a laptop computer or other low-cost digitizer.
Try a CW Doppler radar. You can hack an old police radar gun by locating the video amplifier or mixer’s output and plugging that signal into the audio input port of your laptop and displaying this data using a ‘water fall’ Fourier transform.
If you find an old motion sensor or door opener. These typically use CW Doppler radar modules known as Gunnplexers. Hack into one just as you would with the Police radar.
Or, you can procure new off-shelf X-band CW Doppler radar devices from China for < $10 on Ebay. I’ve used these devices before, they do work but have limited range. This may not matter for your project.
Short range radars sense at 150m or less. At these short ranges extremely short pulses (meaning short in time duration, nS or pS in duration) are required to provide sufficient resolution to be useful. Short pulse, or impulse radar systems, generally follow a simple architecture where the impulse generator is often tied directly to a transmit antenna and a low noise amplifier (LNA) is tied to a receive antenna. A high speed digitizer is triggered off the impulse generator and acquires data on the output of the LNA.
You can incorporate impulse radar technology into your next project. Commercial versions of impulse radars are available to hobbyists and developers. Most notable are the ASIC based impulse radar manufactured by Novelda. These devices do require external antennas but contain on-board radar and high speed digitizers.
Additional impulse radar systems are being manufactured in quantity for automotive applications (blind spot detection, parking aids, etc), but details on these are not easy to find unless you directly engage the manufacturers. Manufacturers of automotive radar equipment include, Delphi, Continental, TRW, Bosch, Denso, and Autoliv.
Frequency Modulated Continuous Wave (FMCW) Radar
FMCW radar was originally used in radar altimeters starting in the 1930′s. Today, FMCW radar is the leading short-range radar architecture because it offers short-pulse radar resolution while providing significantly greater sensitivity with the same peak transmit power. This is because FMCW radars transmit continuously and leverage the discrete Fourier transform (DFT) to increase SNR in proportion to the time over which the DFT is applied. But for a hobbyist the key take-away is that these radars use a simple architecture and radar signals can be acquired by low-bandwidth digitizers such as the audio input port on your laptop, ADC input ports on micro controllers, the lower cost National Instruments NIDAQ units, etc.
For an FMCW radar, a CW oscillator is frequency modulated with a linear ramp. In other words, the CW oscillator starts at one frequency and ramps-up to a second over a relatively long period of time (0.5-10 uS). This waveform is radiated out of the transmit antenna towards the target scene. Some of this waveform is fed to the receiver mixer. What is scattered off the target is amplified by the LNA and fed into the receive mixer where it is mixed with the transmit waveform. The mixing product results in a low frequency (KHz range) beat tone that is proportional to range. The higher the frequency of beat tone the further the target. If measuring a multitude of targets then expect to see a multitude of beat tones superimposed on each other. To measure the range to targets you digitize with a low bandwidth digitizer being careful to synchronize the digitizer’s trigger with the start of the up-ramp. With this digitized data for each up-ramp, apply the DFT. This results in a time domain representation of the round trip time from transmitter, to targets, and back to receiver.
Add an FMCW radar to your next project. FMCW radar devices are available for developers and hobbyists. Some of the lowest cost FMCW radar devices are manufactured by RF Beam Microwave GmbH, who offers 24 GHz FMCW radar modules for less than $10 in quantity, shown here is a K-LC1.
In addition to this, you can build your own ‘Coffee Can Radar’ from the MIT Opencourseware site.
Not interested in building your own coffee can radar from scratch? You can buy a ready-made coffee can radar kit form Quonset Microwave. This radar provides data via a USB or BlueTooth.
And coming soon will be the radar Arduino shield! Credit for this belongs to Tony Long, who developed this shield loosely based on the MIT Coffee Can radar.

Monday, February 24, 2014 - 17:00Lasers: Coming to a Theater Near You #lasers
IEEE Spectrum has a very interesting piece on the future of the movie industry.
There’s a huge push today to develop sophisticated systems that will ensure that the theater experience remains far superior to anything you can get at home or while watching a small screen. These systems will foster the continued growth of 3-D motion pictures, as well as a gradual migration to movies with a higher frame rate, higher spatial resolution, deeper contrast, and even a vastly greater color palette than today’s films.
The upshot is that the next three to five years will see the most significant and the fastest technological transition in the history of motion pictures. For the first time, industry leaders have agreed on the need to go beyond the familiar but optically limited characteristics of film stock and embrace the dazzling capabilities of all-digital motion pictures. At the end of this transition, the optical parameters of motion pictures will for the first time approach the capabilities of the human visual system.
This technological revolution will come from some radical transformations in motion-picture projectors. Since 2000, movie theaters have been switching over to digital projectors. But these projectors continue to rely on a 60-year-old technology: xenon electric-arc lamps, whose brightness fades over time. Even brand new, these lamps are not up to the demands of 3-D movies, especially on larger screens. The movie projectors of the future will replace these lightbulbs with lasers.
In the longer term, digital cinema and laser projectors will far transcend the boundaries of traditional film. Today’s arc-lamp-based projectors can produce only about 40 percent of the colors that most people are capable of perceiving, whereas laser-based systems can reproduce up to around 60 percent. Laser illumination can also project much more saturated colors because its red, green, and blue beams can have much narrower spectral bandwidth than filtered lamp light.
This vastly greater, brighter, and more saturated palette will translate into movies that are more vivid than anything possible today. But such an advance won’t come easily: More colors will require coordinated changes to global standards, and that won’t happen without a lot of arguing over how “wide” to go. More colors will require more bits, which will in turn require more bandwidth to and within the projector.

Monday, February 24, 2014 - 16:01LuxBlaster: Blast a Beam of Light at the Most Intense Light Source
[Hazim] wrote in to tell us about his project that teaches inconsiderate drivers a lesson! Well, theoretically. The LuxBlaster is a spot light which points towards the most intense light source.
The idea is that you can blast drivers who do not turn their high-beams off with a reverse high-beam of your own. It is very important to note that this should never be used, as [Hazim] also clearly states. While this project is meant to prove that it can be done (a “what if”) project, it has two components that are very well done and can easily be used in different projects: the Arduino controlled spotlight and the light intensity tracker.
What would you use an Arduino controlled spotlight for? Smart lighting? What about a light source tracker? Let us know in the comments.

I’ve been interested in learning more about programming microcontrollers and saw that Adafruit has a low cost board (called trinket) that is very convenient since it can be programmed over USB. When I first got my hands on this, I was making sketches for it using the Arduino IDE, but wanted to dive in at a lower level and be able to write C code and reprogram the Attiny85 chip that is on board. There are many different ways to do this, but here is the way I went about doing it.

Monday, February 24, 2014 - 15:00Awesome Bo-Katan Costume
Bo-Katan appeared in the animated series Star Wars: The Clone Wars, and she was one of the first female characters – if not the first – to appear on screen in armor. Mockingbird over at The Dented Helmet forums always wanted to portray a Star Wars character wearing armor, so it was a no-brainer for her to make Bo-Katan’s ensemble. Though she started with a pre-made kit, she had to re-make many of the armor pieces to fit her size. She used Worbla for the job, and here’s how she made the holsters:
In the first picture I’d already made a craft foam base and used a heat gun to get the Worbla to its activation temperature, shaping it around the foam and then placing it on my actual thigh to get a closer, more accurate fit. I then made a holster out of comic book backing board and shaped more Worbla around it before placing it on the thigh plate (Worbla will adhere to itself when heated). Once both holsters were made I used spackling to fill in the edges where they connect to the plate, but forgot to take a photo. The third picture shows post-spackling, and with the first couple of coats of gesso applied. Worbla has a slightly rough texture to it, so applying a few layers of gesso and then sanding it down gives it a much smoother surface. Fourth picture is after priming, and last picture is complete (minus the belts)!
