Mark Miller shared a mobile robotics project: “Small pneumatics system for mobile robotics with regulated air pressure, air logic valves and driver board. The compressor tank is just 5 inches long and can store 4-9 lbs of air to run small cylinders(presetable). The compressor needs 12 volt at 128 Ma, while the valves are 12 volt at 280 Ma. I made the tank from plastics and solvent welded together. The valves were automotive surplus and very inexpensive(49 cents each). The compressors are 5$ each and available surplus also. I am RC controlling these, but easy to run system from a micro. Fun and useful.” (read more)


Michael Mueller shared a 3D project: “A while ago, I saw a guy clamping an old plastic bottle between the seat stays of his bike, to use it as a fender. It doesn’t look very stable but it was a great idea anyway! This 3d printed mount works with most plastic bottles, like Coke, Evian ect. You can just clip it on your bike – no glue or screws needed! I’ve used a bottle which I’ve cut before. Technical, there is no need to halve it but it looks better this way and it’s done easily.” (read more)

Daniel Would shared some more CNC cutting: “Today I tried a more complex CNC cut, with time lapse from a point minted on the machine. Sadly things went badly, trying to push to fast. The pattern screwed up after the x axis bound up. I also think I burned out the power supply I was using. Some days things just don’t go according to plan.” (read more)


Ricardo Lagos shared a watch strap he made: “Seeing all the cool things people make from this community, made me go out and learn how to make my own watch straps. Here is the first one that i finished (buckle is still in the mail)” (read more)

Caleb Kraft and Staci Elaan shared a Thor’s Hammer that delivers an 80,000 volt electric arc from the top: “I wanted Thor’s hammer (Mjolnir), but I wasn’t going to accept any old boring plastic prop. I needed something with a little more POP. I worked with Staci Elaan to build this hammer that has a solid state tesla coil inside. When you push the button, 80,000 volts of electricity arc from the top. It will light up any flourescent bulbs around, scare children, and leave the smell of ozone behind. It is super fun!” (read more)

Over the past couple of weeks, Adafruit staffers Tony Sherwood and I put together something we could give back to the Adafruit community. We seized on the idea of an RGB color picker, the “Koloric Konfabulator” and then featured “Ladyada’s E is for Electronics” — Adafruit awesome Creative Commons coloring book — as the material for participants to color. Check out our video showing how it works! (read more)

Rich Olson on Nothing Labs shared a technique for PCB etching with a a laser cutter: “After a few failures – I came up with the process documented in the video. It works pretty well! I suspect if streamlined a bit – you could go from Eagle to working board in under 90 minutes.” (read more)
