There are still design tweaks needed around the power switch and maybe the jewel but I think this part of the project is approaching a viable state. After this comes programming the UI (How can a RGB pixel ring and a D-pad be used most effectively?) and after that comes programming the spells (Light, Rainbow, Party, speficic LED Patterns, etc.). At that point, we’ll have a level one amulet ready for release.
This amulet is being designed as step one of a platform rather than a purely frivolous trinket. A larger jewel or otherwise modified case could support additional sensors or displays. Maybe a belt buckle or bracer accessory would be more suitable for certain applications. Maybe a tiny epaper screen inside your hoodie’s hood?
Now that we’re all walking around with computers in our pockets, general-purpose wearable computing seems less like a distant potential future and more like the recent past.
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.
