I was working on this red build for a long time. No one can machine the heat sink, but finally, I found out my uncle knows a CNC shop and he helped me make these heat sinks. Finally I can put the laser together. This laser has a Titanium host takes single AAA battery. It is the smallest AAA host you can find. I decided this exotic host needs a special diode, so I give it a Mitsubishi 638nm single mode diode. Here are some pics!!
Finally The heat sinks!!
After some grinding and polishing.
Fitting
The driver board, Sorry forgot to take picture during assembling.
I use LT3080 for wide current range and low dropout. LT3080 at 1.1A only has 300mv drop out. and It has 2 terminal current supply function.
Fitting into the heat sink
Start to work on diode
Put everything together!!
Finally Lazing!!
Some shots of the host and the tail switch
