From the post

I've already posted the dirt side vero so I thought I'd redo it for the complete one with SHO. This ended up pretty compact so will easily fit in a 1590B.

Updated 5th Jan 2014 - ground link added to avoid 2 ground connections to board. LED current limiting resistor also added to make use of available space provided by the additional column.

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.
