Default Yet another 445 build

Built this a little while ago, its a lab-style laser. Only had to buy the diode. Used a piece of scrap aluminum for a heatsink and simple lm317+computer PSU for a driver. Not sure of the power, but according to graphs from this forum it should be around 1.2-1.3 W. It's an A140 diode. Heres a beam vid at night and picture of the driver.


YouTube - 1.2 W Blue laser

Good job
what is the driver's output set at? i'm guessing about 1.3A?
is this your first 445 build?
