Scherb circuit closeup
A couple of you guys asked for a shot of the backside of the circuit board so here you go. One of these days I will draw this out in Adobe Illustrator to make the wiring easier to follow. I basically just took the original diagram from the article, laid out the components on the perfboard to match it, and then soldered up the connections. Given there are so few components it is relatively easy to do this. I used insulation to protect where the wires overlap. In the original configuration I just soldered the LEDs to the circuit as Jeff showed in his article then later on I decided it would be neater to add the screw terminals. I hope this helps. Keep in mind that if you click the image you should get a bigger version popup.
