That's a shot of the whole thing in a Radio Shack project box.
I used a driver design I found on the forums here... Heat-sinked LM-317T voltage regulator, 100 ohm potentiometer, 0.3 ohm 1w resistor (was all I had on hand - going to put a higher resistance one in there soon), 47uF capacitor, silicon diode, master on/off, and a momentary switch to fire it. It's powered by a pair of 14550 cells running in series.
For mounting the laser as well as cooling it, I cut an aluminum CPU heat sink in half with my angle grinder and drilled a hole through it. I picked up a tool at Lowes made to let one drill straight holes in wood for inserting dowels with a standard power drill. Then I took some Arctic Silver Ceramique thermal paste and applied it to the module before inserting it into the heat sink.
I'm only running it at about 100mA right now to play it safe, but I figured this is a pretty good test bed moving forward now that I've got a spec that works... so I'll probably try to build something quite a bit smaller next time.
