Just a few pics of my recent build. Decided to put the case of a defect argon to good use. It makes a nice little split level projector. Still it took me quite some effort to get everything to fit, especially the wiring is much more space consuming than I had originally thought.
Inside are now my old 100mW green, a 500mW 660nm red and the 1W 445. The red is driven by the P3 Flexmod and the 445 by the die4drive. The blue just fits on the galvo mirrors, which makes me pretty satisfied.
The lower level has 5 PSU: +/- 24 V for galvos, 5V for the red and fans, 12V for the 445, and the green's 5V PSU.
The big aluminum thing on the lower level is a air duct from the original PSU that is pressed against the bottom of the optical base plate. Two little fans suck the air through the duct out of the projector. The duct is half ribbed heat sink which makes an excellent heat transfer to the air.
