What you'll be making#

The POLY555 is a polyphonic, analog, square wave synth based on the 555 timer chip.

  • Polyphonic:​ Multiple notes can be played simultaneously. This is opposed to "monophonic," where only one note at a time can be played.
  • Analog:​ There are no computers, microcontrollers, sound samplers, or anything digital involved. The sound you hear is the sound of a speaker being abused by discrete electronic components like capacitors and resistors and logic chips.
  • Square-wave:​ When its output is viewed on an oscilloscope, its wave resembles a square. It’s a β€œhard” sounding wave type, commonly associated with chiptune music and old video games
