I had a gut feeling you were putting something together for me, I was thinking a drawing or maby a schematic or something?? not a video thoughYea, I make heat sinks and some MacGyver builds, I like to do as much as I can with limited tools but I still don't have a lathe or a mill and some times I need better tolorances so I am having parts made by Rich and Tung which is a great help, I really want to do some double 44's and double 7A75's c-lens corrected and with beam expanders but I am waiting for optical parts from Poland.
I am waiting for my rotators from OPT in Poland, it's been 4 weeks, has anyone ordered from them ? How long does shipping usually take ?
131.00 for two little pieces of glass but I need them to build a couple of dual nubm44 with 6X correction and beam expanders, should be real fun fire makers but I still wish every day for some bigger visible laser diodes, I may have to build out some of my ir projects, but I really prefer visible beams.
You mentioned and showed 2 100W 2 ohm resistors. I'll probably order some from China and wait the course.. How much doe's the Ohms rating matter? They seems to have some 5 100W from 1, 2, 3, 4, 5ohms to choose from.
As far as your OPT laser question, we usually come to you for these answers
