Here is my cobbled together attempt at a DIY DVD burner red. I think I half destroyed this thing getting it from the burner though. I dented the front of the diode but it still works. I had a 100ohm pot inthis circuit but the diode would barely lase so I took it out andjust have the 2 10 ohm resisters there in parallel. The circuit draws 175ma from 4 AA alkaline cells and I have no idea what the mW would be since I have no meter. The two stumbling blocks I hit were getting the diode out of the burner and the LM317T I bought from RatShack had a slightly different pinout that the one in circuit that was posted on the forum. I have no idea how strong it is but it produces a nice red beam a night and was fun to hack together. The next one will be a GB diode and a neater circuit. The DVD burner this came out of was a Lite-On 16x DL and the diode was a closed can.
I have a project box from RatShack that I will assemble this into and most likley power it from a 7.4 volt 400 mah lithium polymer battery if it will fit.
