In my collection of circuitry is a carton of vintage circuit boards I call “Chartres” simply because they remind me of medieval cathedral windows. They’ve been saved aside for use in the composition of such a chest as CHARTRES 1, and possibly another. The “windows” surround the sides of the piece, and the top is my impression of the intricate design of stained glass. It’s enough if the design is intriguing, however you see it.
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.
