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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
