My brother-in-law Chris wants to build a wood-fired pizza oven in his backyard. Chris is an aspiring pizza chef at night, but a process engineer by day. Although his pizza oven will be built from age old sand and clay, veins of chromium and aluminum will be running through the walls. These veins are thermocouples, a precision temperature measurement sensor. Four of these thermocouples meet back at the PiMometer, a custom-made circuit board and Raspberry Pi combo. Temperatures from throughout the oven will be displayed on a continuously updating webpage viewable from any smartphone or PC.
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.
