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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
