I'd like to make 1 focusable, with a 405nm glass lens, keep 1 stock, #3 gets a diode "push" test or maybe a driver possible mod only after trying to draw out the circuit and see what I have. If I kill the diode, I will be measuring the ma, it will have a huge heatsink, so I can report where it failed. That still should leave me with the host and a good 85ma boost drive. If I kill the driver....I still have a host and a pretty good 405nm diode left for less than $10.
Please correct me if my thinking is wrong, but this is a 405nm running on a 3v source so it should be a dc to dc "boost" driver?
From a laser noob perspective......I see it as a really "tough to lose situation" if you want to experiment on 405's. I just see a potential for a lot to be learned from an economical 40-50mw 405nm unit.
