So I started a thread in March of this year about building some waterproof laser hosts to take scuba diving. To recap the previous thread, I bought a couple of waterproof flashlights built for scuba diving, gutted them, mailed them to mrcrouse to custom mill a couple of heat sinks, and then...

Well, I posted in the hosts forum not too long ago about looking for some waterproof hosts. I found a couple I liked, and have been working on them ever since. I had mrcrouse do some custom machining for me and now all I have left is to add some diode/driver modules. Let me know what you guys...

Looking to build a diving laser. Need a reasonably priced (maybe $30 or so) host that is depth-rated to at least 150ft. Anyone have any ideas? Alternately, I would be willing to pay a little more if someone could machine one for me. Doesn't need to be anything fancy at all. Actually, it doesn't...

In addition to building laser pointers, I am also a scuba diver. I am interested in building a laser pointer to take underwater (anywhere from 15-130 ft saltwater) to use to point out things to my dive buddy, etc. I have a good quality underwater flashlight housing that I would like to use for...

I'm building a 520nm using the following: (1) Osram PLP520-B1 diode in aixiz module with 3-element glass lens from DTR (1) Micro Boost driver set at 550mA from flaminpyro (1) contact board from flaminpyro (1) copper heatsink from Survival Laser USA (1) C6 Host and drilled pill from Survival...

Hello. Long time lurker, first time poster here. I recently built a ~1.6W 445nm laser using a host, driver, lens, and focus adapter from jayrob and an M140 diode in a module from DTR. I've got my Eagle Pair glasses at the ready, and have read through all the good stickies about safety and what...
