From the post
Very similar to the Drive Master posted a couple of days ago, but thought I'd include the full layout to keep things complete. This version with a diode/LED switch as per a request I had. If you'd prefer yours to be like the original and have fixed LEDs rather than this switch, then just solder in LEDs directly on the board as per the Drive Master layout. The 10u cap will need to be moved 3 columns to the right.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Tagboard Effects. No KiCad fragment has been drawn for this circuit yet.
