FOR JAMES: Soldered, modified POLY555 PCB

A POLY555 PCB, soldered and working to customizations:

  • Tuning
    • Notes will be tuned to range of 437 to 932
  • "Always on"
    • All 20 555s' notes are wired to always be playing
    • No key switches or LEDS for individual notes
  • Output
    • Instead of going to amp, each 555 output will be jumper-wired to 1 pin of a 20 pin header
    • No amp circuit, so no speaker or volume either
  • Just the PCB and its soldered electronics. No plexiglass, enclosure or key parts, or the nuts and bolts for enclosure assembly.
