Oh, nothing fancy, just an analog square wave synthesizer...
- Monophonic: Only one note at a time can be played. This is opposed to “polyphonic,” where multiple simultaneous notes 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 “hard” sounding wave type, great for bass lines, and commonly associated with chiptune music and old video games.
I print everything at .2mm layer height by default.
To get multiple colors, insert color change GCODE at the recommended color change depth. (Assumes .22mm and allows extra room to minimize errant stringing problems, but you should verify in your slicing software before sending to printer.)
|Part||Supports||Infill||Color change depth|
|Bottom||Build plate only||Normal (20%)||n/a|
|Hinge parts||No||Normal (20%)||n/a|
|OKAY text hold-in||No||Normal (20%)||n/a|
|Key plungers||No||Normal (20%)||n/a|
|OKAY text||No||Light (5%)||9.8|
- Clean up strings
- Cut or melt away any stringing. Be careful not to scratch dark filament underneath text embossing
- Enclosure bottom
- Break built-in bridge supports from each PCB post with a small screwdriver or other stabby object
- Cut built-in bridge support from bottom to expose shaft cavity
- One knob has a hole in its side. This is a cavity for the brass threaded insert, which you’ll lock into place by inserting with a hot soldering iron
