Atari2600a's SNESp

i think he meant better, as in one that wasnt 15 years old.

Yes, plus the newer ones are probably more efficient & better built. I know people in another forum who have experienced things like IC's snapping in half & exposing the silicon wafer!

Anyways, I bought a case (& a regulator heatsink) from Radio Shack, & it turns out that the SNES mobo & the screen are slightly wider than the case itself! (It was the largest case at Radio Shack) So what I'm going to cut downward into the case about .75".

I've cut as much PCB as I could off of the SNES mobo, but until I can get my hands on a soldering iron, I can't cut off the last bit of PCB that contains the fuse.

What I still need:

-Battery
-2 switches for the L & R buttons
-soldering iron & solder
-2 speakers

Don't use a 12v battery. Especially if you use a Psone screen. I tried using a 9v in mine, and it screws up the colors on the SNES. Seriously you are better off with a 7.2v battery and it wont get nearly as hot with the heatsink attatched.

My screen uses 12V, & I've already tested the SNES w/ a 12V AC adapter. (for a while too! I almost beat StarFox twice, & got 1/3 through Super Metroid! I did this before I put in the heatsink.)

I might have a problem w/ the heatsink. the hole on it is larger than the hole on the 7805, so unless I can find a screw that size w/ a bolt, I'll have to try to figure out some other way of keeping it on!

By the way, I'm thinking of not installing speakers, but just a headphone jack, because I NEVER use speakers! Even when no one's home! The sound quality is always better on my headphones! (They're studio-quality, w/ the 2 knobs & a ST/MO switch & everything!)

EDIT: Does anyone know if the audio signal coming off of the SNES is powerful enough to power headphones?

the signal should be strong enough, it's at 5v as far as i know, but with headphones that big, you may want to do a led mod if you havent already to save power. have you tried using a 7.2v battery with the screen?

What? No? I highly doubt the signal is even strong enough to power headphones. It's worth a shot, but it's a dumb idea even to bother.

Audio signal at 5v? >_> Doubt that too.

yeah, i was thinking it would be like 3.3v or something.

Post by **Skyone** » Fri Aug 11, 2006 7:54 pm

Try 0v-2v, I think.

off of the snes without amplification the sound is barely audible, you NEED some sort of audio amp

Look on SegaSonicFan's site, I think he has schems for an amp that drives headphones from RCA audio out.

OK, here's a poor mock-up of what I expect the finished product to look like. (the screen's a little dusty)

I take it you're obsessive-compulsive about screen cleanliness as well?

The edge bits around the screen look a little rough, but otherwise, nice work.

Is that a Radio Shack project box?

Once I find some sand paper...

EDIT: By the way, yes it is! It's the largest one they had, which kinda explains why I had to cut a hole in the side to fit the screen.

OK, I got bored today, & managed to get the light box off the back of the screen. I've taken it apart to the point where it's in this list of parts:

-aluminum metal thingy
-3 sheets of whatchamacallit that goes over the glass part
-glass part w/ the lamp thing taped to 2 of the edges
-plastic shell encasing thing

So...What do I do now? (for an LED mod)

Well, cut some of the plastic away so the leads from the LEDs can stick out in the corners, and use a tiny bit of hot glue to hold the LEDs in. You might have to cut away some of the metal so the leads don't touch it, too. Close up the light box, and then you just wire the LEDs together and power them somehow (with the proper resistor in front of them, of course).
