My weekly sailing crew asked for a way to visualise where we had been, and for a live display of the true speed over ground to see whether we were fighting tides. This project delivers both, without relying on internet connections or cell phone data. Add a battery and it would also be useful for car rallies or cyclists. All you need is a Raspberry Pi Zero W with some additional hardware, Python, and Mathematica!

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.
