Hey Guys,
As you can see i am a new account but a reasonable long time lurker, but i've got a few questions about my first laser build.
I have probably got this wrong, so if i have please bare with me and help me out - and suggest alternative parts or methods
Right, my first build - or as i see it in my uninitiated head is that it will use a LPC-815 diode extracted from a sled, it will also use a driver build around a LM317 regulator (described here http://laserpointerforums.com/f42/diy-homemade-laser-diode-driver-26339.html). This is where my first question is, what Ohm resistor do i need to use to pull around 200mW which according to Dr. Lava's graph (http://hacylon.case.edu/laser/diode_red_roundup.PNG) is around 350mA? Would it be around a 3.5Ohm?
Then my second question is about what module/mount do i need for my diode. I have looked at the AixiZ modules and am confused as to which would fit my needs, do these modules come with Drivers in? In which case my LM317 driver is redundant? I am not to worried about a host at the moment so size isn't an issue, this build is more of a proof of concept, that i can actually do it! Basically can you guys give me a few pointers and give me a hand?
Thanks in advance :wave:
P.S. Can anyone recommend some good suppliers/shops in the Uk for this sort of thing?
