Hey I'm from the westbank... living in Abbeville, near Lafayette. I just built a XY Table and im working on a 1W 808nm laser diode for some light cnc work... It's cool to see someone close on here.
I think I figured the power problem out, I ended up with 12 10ohm resistors in parallel, with a total of 1.2 ohms (I know the math doesn't add up), I put them in, turned it on and turned the pot down, my test load showed 1.05A, When I connected the LD it started at about 1.05A then after about...
UPDATE
In trying to find the source of the current problem I connected 7 D Alkaline batteries in series for a total of 7.7 volts, I fed that to the driver, it outputted 7.2V (no load) and 4.2V at 140mA ... this tells me I have more avail amperage from the first LM317 than the 7 D batteries...
Heres the backstory... I Just finished my XY table for my homebrew CNC yay me :) for the Z axis I wanted to use a laser to engrave into light things like plastic, scorch wood, or burn paper. So what I did was a little research (probably not enough) and then I went on Ebay and bought a 1W 808nm...
