Found a lovely old calculator whilst in a second hand shop. The case was broken so I thought I’d make it a nice colourless acrylic case so you can see the internals. Check the vintage display and PCB traces! Can’t beat having a physical calculator to hand, even if it is relatively simple.
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.
