For Version 2, I deployed a piece of instant jewelry I’d brought on the trip. The two-finger ring became a perfect mount point for the battery pack, using some double-sided sticky tape. The tapes helped hold the ring on my hand, too.
It stuck on and didn’t short out in 95-degree weather at Maker Faire New York, and I consider that a success! The battery lasted for hours as we wandered the Faire and the city. I will definitely be using this again.
…In fact, I already have! Someone on reddit requested low-light pics/video, so I stuck it back on with double-sided tape. If your skin is especially sensitive, you might want to stick it to something else first, to weaken the tack. As-is, this worked great.
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.
