From the post
Chris "SPIN Doctor" Stelloh did it again! Amazing work with this box of fairy dust and chaos. The layout is verified and good to go!
...and here is a layout with "Stelloh mods".
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 Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.

Check before you build · 4 values the reader of this layout was not sure of
- CLR1 (col 13, rows I-L) and CLR2 (col 4, rows M-P): LED current-limiting resistors, no value printed anywhere
- R8 (col 28, rows C-H): printed only as 'R8'; the note says stock is 10k and the author suggests higher, minimum 20k
- REG (TO-92 at col 7, rows Q-S): legend prints 'L78l33', taken as L78L33 (3.3V regulator)
- Several parts are drawn semi-transparent (10k col 8 rows C-F, 10k col 19 rows H-K, 1k lying on row M cols 20-22, 1nF col 10 rows O-R, 1uF col 27 rows T-W, 1uF col 29 rows S-T, 1uF lying on row AB cols 25-27): counted as real parts, values legible
