The Sparkling Chameleon Fur Wrap

This is a variant of the Adafruit Chameleon Scarf that I recently made. I made the color fade and randomly twinkle rather than stay on all the time. I also added a button to restart the color sample sequence as well. To include some motion feedback, I used a Fast Vibration Sensor Switch to increase the number of pixels that go bright when it is triggered.

This is using 20 NeoPixles and the wires between them are rather long so that they can be spread out over a larger aria. The color sensor and button are also at the end of a long wire so that they could be placed inside of a fabric sheathe for easy color sampling. This is the same with the last NeoPixle in the chain so you can see the other puffball blink before the color is sampled.

New budget robot is working.

After working on many designs I have come up with this little guy:

I’ve managed to get the parts list price down to just under $30 (not including the 4 AA batteries or optional servo). The chassis is laser cut and I have shared the vector file so anyone can make it. The entire chassis will fit on an 8.5″ x 11″ sheet of paper and is made to be cut from 1/8″ materiel.

I do have plans to design an even smaller and cheaper ($20) bot, but i figured this $35 ish bot would be a good start for anyone who would like to test it out.
