Scout
oskitone·scout·kicad/scout/scout.kicad_pcb
Scout is an open source AVR/Arduino PCB design by oskitone: a 2-layer, 145.3 × 44.5 mm board with 38 components (17 distinct parts). It is built around the ATmega328P-PU, LM386. Filed under audio.
3D-printed, Arduino-compatible, 17-key mono synth. Squeeeee!
1. One sent to obtain information 2. Jean Louise “Scout” Finch, of Atticus Finch 3. The first synth from Oskitone to venture into the big ol' world of microcontrollers
- Beginner-friendly: All components are through-hole (instead of surface mount) for easier soldering, and full assembly takes about 45min. Standalone, battery-powered, doesn't need a computer or external speakers to work. Fun! - 3D-Printable: Besides the electronics and nuts and bolts, all parts are 3D-printed. And with a total width of ~160mm (about 6.3"), the Scout can fit on smaller, "Mini" (18x18x18cm) size print beds. -…
