So, the driver board will need to be heat sinked as well? I didn't know that.

Thanks for the response GBD. I work IT for a living so I have a pretty strong understanding of heat sinking and keeping things cool. I'll have a heat sink on my laser for sure as I have a bunch CPU heat sinks around here in old computers. I just haven't built a laser before, and figure that if...

I've looked around a bit, but didnt see much about this or if it might help. I know heat can be an issue with more powerful lasers. I'm building my first one and want to keep it cool. I have a rkcstr driver and lpc-815 diode. The rkcstr driver will generate quite a bit of it's own heat from what...

I already have the rkcstr driver and do want to use that. But, it does require a minimum input voltage of 5.5v for a red diode. I'll be driving it at about 400ma. I may still be over voltage at 7.2 thought.

Thanks Larry. I do want to use the driver I currency have. I looked into the 18650 batteries and I think I like them. But, these are lithium ion. Can they be drained all the way down? Another hobby I have is r/c cars and we use very powerful lithium polymer packs that have to use a low voltage...

Hello all. This my first post, so go easy on me. :-) I am building my first laser, using a popular combination of a rkcstr v3 micro drive and lpc-815 red diode. I plan to run the LD at 400ma with plenty of heat sinking. What I'd like to know is what is the most compact, longest lasting...
