Why use a PCB silkscreen when you could showcase the shiny gold metal layer? Why build a rectangular board when you could have strange and wonderful shapes? And why settle for a dull LED flasher when you could have something crazy? I went a little bit overboard with this one, and I’m unsure how to even describe it. It’s a wearable LED blinky, with some terrible (or amazing?) abuse of the PCB fabrication process, many eye-catching light displays, and careful attention to power usage to ensure long battery life. For lack of any better name, I’ll call it the Star Ring.
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.
