Wearable electronics don’t always have to be complex sensors for the purpose of improving your health or displaying communication. Sometimes they can just look nice.
Marcus Olssen has done a fantastic job designing this bracelet. You can check out the actual model files at thingiverse and see that he didn’t just create a hollow toriod in which to cram some LEDs. He actually designed this in a way that, when assembled, the LEDs are safely enclosed within the bracelet. There is a removable section that holds the Adafruit Trinket and the battery, held into place with neodymium magnets. This removable section serves to make the bracelet easier to put on as well as easier to charge/reprogram.
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.
