I'm gonna guess here that not all of it is wired up properly....from looking at your diagram there anyway lol.


Umm....from looking at your diagram...Are you actually trying to push the wall AC straight into the 7805? :shock:

The 7805 only regulates DC current, not AC. You need an 8-12volt (output) transformer. This is probably why nothing is working, and why the 7805 is heating up so much.

It takes alotta abuse to cook a 7805, so it may still be good...

Also, do you have the capacitors on each side of the 7805? They're kinda important too lol. As is having a resistor hooked in series with the LED to keep the LED from burning out. I'm guessing you'd probably need somewhere round a 160-180 ohm resistor in there to keep future LEDs from burning out.

Oh sorry, I should've updated the wiring diagram. I forgot to draw my groundwire on there. :/ Also, the AC from the wall is going through an adapter that outputs 12v DC.
I've made a huge mistake.

Ok, after FAR too long my creation is complete. I worked on it off and on while getting my degree. I finally got my degree, and I finally finished my ammo can Nintendo.

BTW, my degree is one of those useless ones, so I'm considering parting with dear old NESsie here.
