First up is the little plastic bobbins we use to spool our conductive thread http://www.adafruit.com/products/603 on, these little guys are basic plastic bobbins. They’ll work in many machines as well, but for spooling small amount of thread these are awfully cute and very low cost – about 15 cents per and with fast shipping from a USA seller.
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.
