This is total zombie apocalypse stuff. Let’s say the world’s ending, there’s no more electricity and you need a knife. But all you’ve got are a roll of aluminum foil, a source of open flame and some unpowered hand tools. What do you do?
Admittedly, not all of you are going to have the sharpening media lying around, unless you’re knife nuts or hand tool woodworkers. But the fact that this is possible at all beggars belief.
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.
