[Finchronicity] over on Hackaday Projects has made a pretty awesome furry LED Vest to keep him warm and well lit at this year’s Burning Man. He is using a Teensy 3.0 that drives strips of 470 WS2811 LEDs.
The vertically aligned strips run on a continuous sequence which reaches up to 31 frames per second using precompiled animations. The effects rendered in Processing or video mapped, are captured frame by frame and stored as raw color data to an SD card. Playback uses the NeoPixel library to control the strips. The high resolution LEDs, with the video mapped fire and the long pile fur, create one of the nicest flame effects we have seen on clothing.
We’ve also seen the Teensy 3.0 and WS2811 LEDs used as a popular combination for building huge displays, a 23ft tall pyramid, and more recently in the RFID jacket at Make Fashion 2014. Have you made or seen a great Teensy/WS2811 project you would like to share with us? If so, let us know the details in the comments below.

Mercredi, Avril 16, 2014 - 23:17How to make your own Primo prototype using digital fabrication and Arduino boards
Primo‘s team sent us exciting news from their HQ about their contribution to the open source community. After the successful Kickstarter campaign to launch the wooden play-set that uses shapes, colours and spacial awareness to teach programming logic through a tactile, warm and magical learning experience, they took a step further. They released all the documentation and the instructions to produce a Primo prototype, different from the product that they make and sell.
We just finished the first edition of the Primo play-set open documentation, that includes the design files that we used to make our first prototype and a step-by-step guide to make your own version of the Primo play set. This “maker” version of our product can be assembled using rapid prototyping techniques and common tools like Arduino boards.
We recently published a preview of this documentation just for our Kickstarter backers, who already started to build their projects and to translate the document in their language. The FabLab in São Paulo for example already translated it in Brasilian Portuguese, while other languages like Dutch, Italian and Japanese are now in progress.
The whole documentation is completely transparent: it’s written in Markdown using Jekyll and GitHub pages. In this way it is very easy for creators to modify, translate and use it as a starting point for their projects.
In parallel we are developing an industrial version of our product, using manufacture-quality materials and custom Arduino-compatible electronic boards.
And if you want to read about the experience of a dad making a DIY version in 1 month and a half of work, follow this link.
Primo is an Arduino At Heart partner. If you have a great project based on Arduino and want to join the program, read the details and then get in touch with us.
Mercredi, Avril 16, 2014 - 23:00How To Make Your Cosplay Props Look Like Metal
Making plastic or craft foam look like metal isn’t the easiest trick in the world, but it can be done. This is a great skill to learn to help you with cosplay props and weapons and also armor. DeviantArt user Risachantag came up with it. First, the plastic shuriken were coated with a base coat of chrome spray paint. To make it look more like worn and used metal, she used a dry brush first. After you dip your brush in black paint, do the following:
“Scrub the brush on newspaper for a bit until there’s only a little bit of paint on the brush. Putting pressure on the brush until it splays out, scratch the brush around so that the paint comes off the brush unevenly to give a rough texture.”
See the full tutorial at DeviantArt.
Mercredi, Avril 16, 2014 - 22:00Re:load Pro, an Open Source Active Load
Open source test equipment has to be one of the best gifts open source hardware has given back to the community. Nowhere is this more true than in the case of [Nick's] Re:Load Pro over on Kickstarter. Unlike resistors or similar dummy loads, an active load will always draw the set amount of current regardless of voltage. Active loads are often used to test power supplies and batteries. Is that 2500 mAh LiPo battery overstating it’s capacity? Can the power supply you just designed handle 2.5A at 12V? Both of these are jobs where active loads would come in handy.
The Re:Load Pro is actually the third version of the Re:Load. [Nick] designed the original Re:Load after becoming frustrated at the lack of a cheap active load for testing a power supply. Plenty of people showed interest in the Re:Load, but they wanted more features. That’s where the Re:Load Pro comes in. More than a straight analog design, the Pro has a Cypress PSOC 4 Arm Cortex M0 processor running the system.
[Nick] and his company, Arachnid Labs, are no strangers to us here at Hackaday. When we last covered [Nick], he was asking the USB Implementers Forum about a low cost Vendor ID option for open source hardware projects. Fittingly, the Re:Load Pro is an open source project. The schematics and source code are available on Github.

Mercredi, Avril 16, 2014 - 19:01“The Maker Movement”: Wall Art For Your Workbench — Prints Now Available
I’ve wanted to do a photograph which captured what I think of when I think of makers, and which makers themselves would enjoy as a work.
All of us started the same way — as curious kids (maybe big kids). At first, most of us were following in the path of someone else — along what feels like a straight, well-defined line. But there’s a point where things start to diverge, and we go off and do our own thing. That’s what making is all about, and that’s what I tried to capture here.
Symbolism aside, I just dig this image. I’d like to sell it as a print, with a portion of the proceeds going to charity. What I’d like to know from you is if you’d be interested in buying such a thing. It’s always hard to judge whether or not a print will sell, especially for the artist, who is often too close to the work to be objective — that’s what galleries and curators are for. But I don’t want this to be a gallery piece. I’d like it to be an affordable work that people can hang in their homes, hackerspaces, shops, or offices and enjoy, so I’m asking you directly.
Many thanks to everyone for your compliments and support! It’s been a long time coming, but it’s finally here (yay!) — head on over to the SmugMug page to check it out!
Mercredi, Avril 16, 2014 - 19:01Building the Internet of “Thing” at FTF2014
It’s official: all the hype around IoT is starting to get a bit annoying. Not because there’s anything wrong with building Internet-connected devices, but because so many people are trying to jump on the bandwagon with the same old “Future: brought to you by Megacorp #07″-mindset. Recycled visions of estranged professionals, with their homes, offices, business meetings and hotel rooms, all powered by the latest “one IoT platform to rule them all” – are back on. Even though the mythical “Smart” refrigerator didn’t changed the world back in 2001, I guess that there’s no harm in trying it again. After all, we have seen this working out great in software, with redos of dot-com era ideas turning into massive successes a decade later.
That’s all fine, and we wish everyone the best of luck, but the future we’re the biggest fans of is a hackable, community-built, open-hardware one. So when the guys from FTF2014 called us to host a two-day “lab” in which engineers would play around and try to come up with an interesting IoT product, we were more than happy to jump in and try to do it our way. We got roughly two dozen engineers to drop lectures and training classes and hang out with us in the lab. We got Freescale to hand out a whole bunch of FRDM-K64F boards and a couple of mbed.org guys to join us on-site and help out with the dev tools. Two days later, we had our winner – “Don’t Not Enter” by David Isbister and Ernie Aguilar. They did an amazing job, both in hacking up a great product (elaborate internet-connected cat flap door), but more importantly, in fixing a whole bunch of issues in the hardware/firmware/tools stack that we had on our hands. However, a true disruptive technology that came out of the whole event was our second-prize winner – Eli Hughes, and his project called: The Internet of “Thing”. You’ve guessed it – it’s the (Internet-connected) Thing from The Adams Family! In this ultimate display of subversive playful cleverness, Eli did more than just creating an interesting project. He called out a large audience of otherwise buttoned-up “professional” engineers to start thinking beyond RFID and obvious Smart devices and try to bring back a little bit of that wacky hacker spirit back into their work. Eli’s project is pretty interesting on the implementation side too. He did some clever surgery on Fantasma Toys Hand Runner to boost the power and created a circuit that interfaces Thing’s built-in IR remote to the WiFi. He also built a cool command line interface and a touchscreen app, which communicate with the Thing via TCP server running on K64 board with RX-XV module. This setup allows for endless hours of fun, either by controlling the Thing via touch interface, or more importantly – by scripting its movement using the DSL shell. For more details, check out his project entry at hackaday.io. Hopefully, this project will serve as a great reminder for all of us that the future is not going to be just a “photorealistic version of Second Life” and if we’re to build projects that define it, we will have to try harder and come up with some truly creative and original ideas. And make sure we’re having fun along the way.

Mercredi, Avril 16, 2014 - 18:30Easter Egg code for the Eggbot! #eggbot
With Easter on its way, we’ll be featuring one fun Eggbot related post each day through Sunday! User ragstian from the Evil Mad Scientist Eggbot forums found the code for an Easter Egg!
Over in the Eggbot forums, user ragstian has been poking around in the firmware for the the controller board for the Eggbot, the EBB. He found an easter egg: holdover code from an old demo mode which would do standalone plots without a computer attached. The plot above depicts one of the very earliest versions of the Eggbot kit.
And on the reverse, www.egg-bot.com. Nicely done!
Mercredi, Avril 16, 2014 - 18:22MetaWear BLE Wearables Platform #WearableWednesday
Check out MetaWear, a Bluetooth and processor module aimed at app developers who want to get prototypes up and running quickly:
Instead of uploading your code to the micro-controller board, it comes pre-loaded with its own custom firmware — sort of like an Arduino running Firmata — and you talk to the board from the MetaWear’s Android and iOS SDKs, or using a generic Bluetooth LE library like noble from node.js. In other words, you don’t have to worry about cramming the smarts of your wearables into the limited computing power of the board itself. Instead, you use your smart phone and its sensors — accelerometer, magnetometer and gyroscope — and location information — Wi-Fi and cell positioning, and GPS — without having to roll out any hardware.

Mercredi, Avril 16, 2014 - 16:00Building a Mesh Networked Conference Badge
[Andrew] just finished his write-up describing electronic conference badges that he built for a free South African security conference (part1, part2). The end platform shown above is based on an ATMega328, a Nokia 5110 LCD, a 433MHz AM/OOK TX/RX module, a few LEDs and buttons.
The badges form a mesh network to send messages. This allows conversations between different attendees to be tracked. Final cost was the main constraint during this adventure, which is why these particular components were chosen and bought from eBay & Alibaba.
The first PCB prototypes were CNC milled. Once the PCB milling was complete there was a whole lot of soldering to be done. Luckily enough [Andrew]‘s friends joined in to solder the 77 final boards. He also did a great job at documenting the protocol he setup, which was verified using the
open sourcetool Maltego. Click past the break to see two videos of the system in action.
