That's Okay! - Monophonic: Only one note can be played at a time. This is opposed to "polyphonic," where multiple notes can be played simultaneously. - Analog: No computers, microcontrollers, sound samplers, or digital components are involved. The sound you hear is the result of discrete electronic components like capacitors and resistors abusing a speaker. - 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. These are the 3D models for the OKAY DIY Kit. Read more about the project, its design, and where it's headed here. Differences from OKAY 2: Fewer keys, keys mounted to enclosure top, key plungers, no audio out jack #### Printing instructions ##### Slicing I print everything at .2mm layer height by default. To get multiple colors, insert color change GCODE at the recommended color change depth. (Assumes .2mm and allows extra room to minimize errant stringing problems, but you should verify in your slicing software before sending to printer.) <table style="width: 100%; table-layout: fixed"> <tr> <td><strong>Part</strong></td> <td><strong>Supports</strong></td> <td><strong>Infill</strong></td> <td><strong>Color change depth</strong></td> </tr> <tr> <td>Bottom</td> <td>Build plate only</td> <td>Normal (20%)</td> <td>n/a</td> </tr> <tr> <td>Top</td> <td>No</td> <td>Normal (20%)</td> <td>n/a</td> </tr> <tr> <td>Hinge parts</td> <td>No</td> <td>Normal (20%)</td> <td>n/a</td> </tr> <tr> <td>OKAY text hold-in</td> <td>No</td> <td>Normal (20%)</td> <td>n/a</td> </tr> <tr> <td>Keys</td> <td>No</td> <td>Light (5%)</td> <td>n/a</td> </tr> <tr> <td>Speaker</td> <td>No</td> <td>Normal (20%)</td> <td>5.4</td> </tr> <tr> <td>Labels</td> <td>No</td> <td>Normal (20%)</td> <td>6.4</td> </tr> <tr> <td>OKAY text</td> <td>No</td> <td>Light (5%)</td> <td>9.8</td> </tr> <tr> <td>Knobs</td> <td>No</td> <td>Normal (20%)</td> <td>18.4</td> </tr> </table> ##### Assembly - 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. - Knobs: Cut built-in bridge support from bottom to expose shaft cavity. One knob has a hole in its side, which is a cavity for the brass threaded insert. Insert it into place using a hot soldering iron.
