I reported about the Red Bull Creation Contest before, and also on some of the curious creations that were announced during the last weeks. But now the final creations are submitted and you can vote now for the most amazing ones 🙂
Did you ever thought about selling one of your hardware creations? Maybe some gadgets built on Arduino, Raspberry Pi, 3D printed artefacts as well as specific shields, boards, sensors or complete kits.
Emile Petrone founded a marketplace, tindie.com, where makers and hardware creators can offer their creations. There are already some really interesting creations on tindie, such as an Angry Birds-playing robot, MicroFTX USB-Serial Breakout or a Netduino Go! Relay Module.
This week in the MAKE Flickr pool we saw…
Check out this lovely Solar Stella cigar box amp built by John Wilson of Minneapolis, MN.
My original plan for this amp was to make a rather rugged poly-coated wood enclosure that could stand up to being left outside in a light rain. On the other hand, I also wanted to finish my amp by the time that the Minne Maker Faire rolled around. I quickly realized that my woodworking skills were not up to the task of being able to make an amplifier enclosure with the time that I had.
I started looking at what cigar boxes I had on hand. I considered a number of them, but ultimately decided on a Romeo and Julieta box that I picked up at a thrift store. It was a hard choice, because this particular box has some very beautiful cover art on the lid (inside and out), and I would have to cover it up with the solar panel. I decided to cover it up with the solar panel anyway, because I could see the original artwork when I opened up the lid.
The Solar Stella is a variant of John’s Stella Amp kit that he sells.
Write an Android app to control an LED light shirt. The app communicates to an ATmega128 via a BlueSMiRF Bluetooth transceiver. The microcontroller outputs data on the SPI to daisy-chained shift-register-controlled constant-current regulators driving RGB LEDs.
