As you probably recall, I made a homemade driver from recommended parts. It's an LM317T with a rheostat and just in case resistor then a capacitor and one direcitonal current diode thingy then a LD. So along with the capacitor and diode, I also added in parallel two wires with aligator clamps...

Well I rigged up your standard do it yourself driver on a breadboard with parts identical to the one in the video from Phazonx in that other post. Another diagram I found elsewhere recommended a 4ohm resistor and his recommended two 10's in parallel for a 5 ohm resistance so I just went with...

I've been poking around and eventually found 2 conflicting wiring diagrams for driver circuits.  Actually for all I know they do the same thing cuz I dunno advanced components that well.  But otherwise, which one of them is correct. Btw I dunno why he added dual 10 ohm resistors.  Maybe he was...

I've noticed a significant lack of build your own diode threads here so I think I already know the answer but I'll still ask :D You know how if you have some tungsten and it's thick enough to not immediately oxidize, you can run current through it and tada, you've got a homemade lightbulb? Or...

I'm doing a variation of a minimag maglite with a DVD diode with case in place of the bulb project. I'm using the recommended 12X30mm brass case from mfgcn.com. They have specs for basically every case BUT the 650nm 5mw one I ordered. Not that the specs really mention this either though lol...
