Here is the new Adafruit packaging for iNecklace and iCufflinks! These are made in the USA, anti-static black boxes, great for other electronics projects too! If you pick up a set of the cufflinks for father’s day, they’ll ship out in the new packaging!
NEW PRODUCT – Snap-action 3-Wire Block Connector (12-28 AWG) – Pack of 3. These are like the fancy electronics equivalent of the wire nuts electricians use to bind wires together. They are a lot easier to use as well! Each block connector has a metal block inside and three levers that snap open and close to bind stranded/solid-core wire. No screwdrivers required! They’re super handy for free wiring and can handle up to 20A at 300V with UL listing so you can also use them for mains wiring. Use any wires from 12 AWG down to 28 AWG. Each package comes with 3 pieces of 3-wire blocks.
If you start tinkering with electronics, eventually you will want to make your own printed circuit board, or PCB as it is generally called. In the olden days, this subject was pretty straightforward. You went down to your local RadioShack, and bought an etching kit. You drew your single sided design using a marking pen and some supplied stickers. The board was fairly big, and it had only a few simple through-hole components.
Those days are now pretty much gone. Now most electronic projects are much more complex, the boards are much smaller, and you need to deal with 2 layers, surface mount components and vias. In this overview, I will tackle the different problems you may encounter and the methods available. I won’t cover PCB layout software or commercially made boards. I’ll deal with those topics in separate articles.
The Raspberry Pi received an extraordinary amount of pre-launch coverage. It truly went viral with major news corporations such as the BBC giving extensive coverage. Not without reason, it is groundbreaking to have a small capable computer retailing at less than the price of a new console game. There have been a number of ventures that have tried to produce a cheap computer such as a laptop and a tablet but which never materialised at these price points. Nothing comes close to the Raspberry Pi in terms of affordability, which is even more important in the current economic climate. Producing a PC capable of running Linux, Quake III-quality games, and 1080p video is worthy of praise.
Adafruit Pi Box – Enclosure for Raspberry Pi. Keep your Raspberry Pi® computer safe and sound in this lovely clear acrylic enclosure. We designed this case to be beautiful, easy to assemble and perfect for any use (but especially for those who want to tinker!)
The case comes as 6 pieces that snap together, made of crystal-clear acrylic. This ingenious design has no screws or standoffs and there are cute little feet cut into the sides so that it stands up above your desk. There are engraved labels on all the connector slots. You can use all of the connectors on the edges of the Pi: HDMI, Audio, Video, SD slot, micro USB power, Ethernet and the two USB ports. We also added a slot so that you can connect a 26-pin IDC cable to the GPIO breakout pins on the Pi and pass it though the case. For more advanced hacking, the enclosure is designed so that you can remove the top piece and plug any sort of cables you wish into the breakouts in the middle. The case is airy enough that no additional vents or cooling is required – we tested the enclosed Pi over a 24 hour period at full load with no significant increase in temperature.
This product comes with the 6 acrylic pieces. Raspberry Pi computer is not included. No other cables or connectors or accessories are included.
What is the Raspberry Pi® ? A low-cost ARM GNU/Linux box.
The Raspberry Pi® is a single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of stimulating the teaching of basic computer science in schools. The design is based on a Broadcom BCM2835 system on a chip (SoC), which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 256 megabytes of RAM. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. The Foundation plans to support Fedora Linux as the initial system software package/distribution, with support for Debian and Arch Linux as well – Wikipedia.
I was able to solder up and complete the Game of Life kits in time for display at the IEEE’s booth at the Seattle Science Fair. The event was a success, with the goal to attract children and the young at heart to see something cool and ask questions regarding the world of electronics. Two parents asked where we purchased the kits and I gave them the Adafuit’s name and website.
This is a port of the Arduino based Arducopter Drone software to Flash for users to try AC’s features and to learn how to tune their drones. I hope it helps users learn more about PIDs, flight control, and sensors as well as prevent crashes of expensive drones!
Pacing around his Brooklyn apartment, Tommy Mitchell paused to eye his machine with frustration. On top was an 85-watt solar panel that he realized he had just installed upside down.
A solar-powered cellphone charger, it looks like an oversize white iPad on stilts, with eight charging wires sprouting like tentacles from the middle. Once charged, the machine, which sits on a huge battery, can run a whole week without sun, he said.
Every day, we come in contact with objects that are injection molded – one of the cornerstone technologies that define our modern world. Injection molding allows designers to create extremely complicated parts with relatively low part cost after a (usually expensive) initial investment in an injection mold.
Injection molds are often closely guarded trade secrets – Legos is said to bury worn-out molds in the concrete of its new buildings. However, since we are an open sourced project, working closely with our manufacturing parters, I am able to give you a behind-the-scenes look at how injection molds are built.
I was inspired to do this project after going to Bonnaroo for the first time last year. The idea I had was to take a programmable belt kit, hook it up to an Arduino microcontroller and microphone and make a wearable VU meter.
By popular demand, we now have a project tutorial for how to make your own programmable, ultra-blinky LED belt. Perfect for parties, raves, parades, weddings, funerals, and bar mitzvahs. Wear it with pride, wear it with blinky! Follow our soldering tutorial to build your own heirloom LED belt, and hand it down to your grandkids.
Open Hardware Summit alum (and all-around awesome guy) Daniel Reetz is releasing the first version of his DIY Book Scanner kit. This is a beta run of 8 units: mostly intended to work out the kinks in the assembly instructions, but all of them assemble into working book scanners. These are similar to the prototype Dan demoed at OHS and World Maker Faire last year (his OHS talk is above, top). He writes:
The latest in DIY Book Scanner technology.
Kit includes all necessary hardware, LED lighting, bicycle-lever triggers, cables, etc. The complete hardware is pictured. These first 8 kits will have extra-special support direct from Daniel.
Kit does not include:
This price includes shipping in the USA. At first, I will only ship these scanners domestically in the US so please do not order if you are outside the USA.
The ability to preserve the printed word is a valuable service, and a book scanner is something which I feel every hackerspace should have. A “book scanning day” would be a great service project for a ‘space, and would draw out members of the community that might not otherwise visit. In his own words:
“the goal is to get one within driving distance of everyone on earth, starting with hacker/makerspaces. Not everyone needs a book scanner of their own, but everyone needs access to one.”

3D printing seems to be the latest trend in hardware, and people are getting more and more aware about this impressive technology. At least, this is what this insightful 3D printing survey reveals. I have always been curious about how would people react to such a technology like 3D printing and some good folks have created this software to answer m questions.
The survey brings up interesting data which suggest that the world is getting ready for a complete shift regarding the industrialization of our societies. Can you imagine what would a world with 3D printing look like? You’d be able to create so many things inside your home, with your computer and a 3D printer: toys, garden tools, office things, screws, flowerpots, vessels, boxes and so, so many other things.
At Musichackday Amsterdam I built a musical umbrella together with Julia Läger (and Peter the Multimeter). Falling raindrops are detected by piezo sensors and turned into 8 bit sounds. Read the Wiki article here.
