I thought, somewhat, the module made up for the lack of a heatsink? The last laser I built didn't have one, I don't think, and I could leave it on for a few minutes at a time... but this'll be more powerful, won't it? What specific part would be suggested, then? Also, for the static, I assume...
I was kind of planning on just mounting everything to a piece of wood, letting me look at or edit the components easily, see if anything broke, etc. So, if I wanted to, I could purchase all the stated items, get the tools, and build a 300-400 mw red burning laser, right?
Diode, check. Driver, check. Module, check. Wiring, I have some laying around which I've used for other things, works great even with pretty high voltage, check. Batteries, check. Heatsink and host, I thought were decided to be unnecessary? Correct me if I'm wrong, please. What do I do about the...
Anything else is more money out of pocket, which isn't going to the laser itself, and I could just use a vice in school, so why spend? Just so I've got this down pat, with a soldering iron, the stated diode, the stated driver, and the 5.6 Aixiz module, I can get this to work with 3 AA batteries...

Would that work well as the diode? If so, what would I need to attach to it in order to make it work?
