Yoghurt pots make great resonant bodies (especially Stichfestes Yoghurt:-). So weaving the speaker membrane from the rim of the pot seems like an obvious opportunity. This post documents how to puncture holes around the rim using a hot needle, thread a circular warp and then weave in and out around in a spiral alternating between an uninsulated highly conductive thread (Karl Grimm silver plated copper) and an insulating cotton thread.
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.
