BackRoughly on Moritz Klein's work, but with buffering between (some) stages. Needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a momentary-on button to advance the step LED + 23mm hole_left = slider_center - 13; hole_bottom = hole_top - 89.75; hole_right = hole_left + 78.5; // Step count (sw11 // step rotary switch - 9.5mm, +5mm extra space micro toggle switch | Dailywell | PAS6B3M1CESA3-5 or PAS6B3M1CESA2-5 | Tayda | A-001 | | | | U3 | 1 | B10k | Potentiometer | | | Tayda | A-1672 | | R23, R24, R25, R27 Switch, triple pole double throw, illuminated paddle, red and green LEDs K switch normally-closed pushbutton push-button LCD D MEC 5G single pole double throw, separate symbols K switch dual-pole double-throw spdt ON-ON K reed magnetic switch D Single Pole Single Throw (SPST) switch, small symbol D 8x DIP Switch, Single Pole Single Throw (SPST) switch, small symbol D 6x DIP Switch, Single Pole Single Throw (SPST) switch D MEC 5G single pole double throw, separate symbols K switch sp3t ON-ON-ON.
- Maybe an updated one exists with current ICs?
- Rail clearance issues, add PCB slot, more options.
