ASAP. I encased it with glue. I think its the smallest ever! I'm on a different comp. I have to wait untill my other one is back on, it has the pics. My internet connection isn't very stable right now. But, to make you feel anxios, it totally pwns.

Holy crap thats small! I have one question about LM317's, is the tab ground? It said on the package that it is adj, and I don't want to fry another N64 (the first was due to 7.2v sparking to the 3.3v line).

I don't know. Just whatever Sky's diagram calculator says is ground. There is no ground in/out. You just insert ground in to the correct spot. I think I will make a diagram. BTW: I'm using a HB317. It's the same as a LM317.

I think the tab on the LM317 in Vout.

So hooking it to ground/the heatsink would be bad?

Ya, don't hook the heatsink up to ground.

Ok, so it was a good idea to wrap the lm317's heatsink in electrical tape before putting it on the main heatsink.
