It consists of a small Tim Holtz Lantern that had an incandescent bulb powered by 2 AA batteries, which I retrofitted, removing the cheapo flashlight bulb and replacing itwith a white LED. The wires run through black necklace chain to a battery pack that my friend will wear tucked in her corset.
The battery pack is a cool little case from New Age Electronics (via Mouser) that combines space for 2 AAA batteries (more than enough juice for this) and space for a small circuit board on the opposite side.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
