Reply to "How do I wire an ngineering mars light simulator to an evans design LED?"

So... I ended up running into another problem. I assembled the circuit and tested it with a small, incandescent bulb. I attached two wires to the board and connected them to the track and slowly increased power. The bulb lit up, but the wires started sparking where they contacted the rails, and then the LM78L12 voltage regulator started smoking. I checked the circuit multiple times before testing it, but I either missed something or I'm misinterpreting the schematic. Does anyone see a mistake in the attached pictures (besides sloppy soldering)?
