2 minute improvisation on a BEAM-inspired minimalist 9V noise synth. Featuring: a 4093 (Quad NAND), 3 capacitors, and 4 homebrew force sensitive resistors. All in a compact, hot-glued, entomoid form!
Note on homebrew FSRs: conductive foam sandwiched between two single-sided copper plates. Solder wires to the two plates, hot-glue two outside edges of the foam to the plates. Mine do ~1 Ω-1 MΩ Larger-celled conductive foam returns to "neutral" shape faster (e.g.: PIC foam), smaller-celled takes longer (e.g.: ATmega foam).
