Paul Schow built this fantastic homemade satellite tracker – and for cheap! He says, “I’ll tell you straight away that my solution ended up costing more than $25, but I think someone could make the same thing for $25.” Challenge accepted! His post is very thorough with pointers for decreasing weight and cost, using off-the-shelf components for solutions, and FOSS solutions for getting everything to talk to each other.
Check out this sped-up version of the tracker’s movement:
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.
