From the post
An old request that I thought was a joke. But here it is!
The schematic for this monster is avaiable HERE.
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 · 5 values the reader of this layout was not sure of
- D6/D7: legend says D6 1N5817 and D7 3mm LED, but the board draws D6 as a round red LED beside the LDR (row L-M, col 25) and D7 as a small black diode by the 9v pad (row W-X, col 3); the legend looks swapped. Rows follow the legend.
- D3-D4 printed 'ISS174' in the legend; read as 1SS174
- 3.3uF (row Q, col 29-30) and one 1uF (row V, col 30-31) are drawn as transparent round cans lying on a strip with no polarity stripe; taken as electrolytic
- Q2 alternative printed '2N5501' in the legend, probably 2N5551
- 36K x2, 750K: printed clearly, unusual value
