I saw that Bengal had a driver board that looked home-made. Just wondering how this was done.

Hi CTR...
Welcome aboard
I believe it was this circuit he used .. Courtesy of Sam's LaserFAQ
http://photonlexicon.com/albums/album07/laser_drv.jpg
If he ever comes back and visits us , He can tell you for sure how he etched it..
I imagine he used double-clad PC board material and drew the circuit traces on with a black "Sharpie"
then used etchant solution (Ferric Cloride) to develope the board (eat away the unused copper).
Hope that helps...
