My idea for power

G-force · Post by **G-force** » Sat Jan 29, 2005 7:29 pm

I tryed a voltage regulator for the 3.3v line and I got it to power on...for about 45 secs, and then it over heated and fried! So I'm pretty much done with regulators for now.

So my idea is that I use some car DC-DC converters from Radio Shack. They are really nice, low heat, and they have an electronic fuse so I can have a DC power in jack without worrying about my brother inserting a reversed polarity plug and frying the N64

I'm thinking I'll use a 5v converter and bypass the 12v in line for the N64 mobo, and also bypass the regulators on the PS one LCD with it. That should save some power. Also I'll use a 3V converter for the 3V line on the N64.

I think it should work great,

what do you think?

It wont. The chips use 3.3volts. They NEED 3.3v. If you put 3 volts in the gpu and ppu do not functgion properly. The sound sucks and the video is fuzzy So just get a 3.3volts converter

yup, jack's right, the sound will get fuzzy and the video gets a bit distorted

. it's not all bad, though, while using only 3v it's still playable, only slightly annoying that the picture+sound aren't perfect.....try finding a different converter that outputs 3.3v rather than 3v

Really? I used a 3v car converter on my second N64P and I never noticed anything wrong with it at all.

I'm pretty sure they don't make 3.3v car converters, so I guess I am back to trying (and frying) voltage regulators (hey that rymes!)
Has anybody actually gotten one to work?
I have had no luck at all with them. They always overheat and go kaput!

run them in series

try heatsinking the regulators. if they're still overheating, perhaps you've wired something wrong......

i meant run them in parallel

Well all a 3v converter means is that its around 3v. Most things like that have a few percent tolerance...

I believe the GBA SP's recharageble Lithium-Ion battery pack is 3.3V(Not 3V, 3.3V, I've seen an SP opened up). Has anyone considered using them once the SP has a substantial price drop within the next couple years, or ordering some from Nintendo?

you can get replacement SP batts at radioshack. i put 3.6V into my n64P and i didnt notice any sound/video problems

Do you know how many mAh they are and what they cost?

Somewhere in between 300 and 600 mah...

Hmm.. You vould have one SP battery for the 3.3v line and two in series for the 12v line. That could actually work!

yeah, except it wouldn't even last 30 minutes

You could just play really fast

You couyld become a speed gamer that way.
