Thanks for the info!
YES- The PS3 5mm cubes are the ones! Rubberband was kind enough to send me 4 of his from the PS3 sleds he parted out.
As for spacing, I'm planning on decreasing beam diameter going into the cube, and hoping I dont exceed power/cm^2 ratings for the little things!
I'll take all of those little 5mm cubes I can get - they work really well.
As for the case- the case is really curvy - a very ergonomic design, fits the hand really well, molded rubber inlaid grips, thumb trigger on top, heatsink on bottom, recessed to prevent it catching when pulled from pocket, inlaid polycarbonate window for view of power monitor and - the ultimate finishing touch - a flip-up eyeshield for viewing close-range burning w/o needing goggles (the 3" distance setting).
Hence the need for plastic - wayyyyy too much detail and "stuff" to do simple fabrication. Gotta be molded.
I've been playing with combining beams from my 5mw pointers and have successfully combined 3 beams so far (one from the straight through side and two from the reflect side - only because I'm now working on figuring out how to gang the diodes effectively).
What I'll really need as I approach actually taking the leap and investing in the case - will be a power meter so I can verify that the beams are tuned to MAXIMUM proper polarity orientation, and that I am getting the power output I expect, not that it just LOOKS a lot brighter and seems to burn faster & deeper... the power meter will tell all!
But for now... back to "real" work, as I have clients who have sent me stuff to get live this weekend, alas. Would that I could make tons of money by just doing whatever I felt like doing at any given moment!
LOL!!!
