im not sure but you hight need higher wattage resistors

Godzilla · Post by **Godzilla** » Sat Jul 23, 2005 3:54 pm

The ones I'm looking at are these:
1/2W 470 ohm resistor
1/2W 680 ohm resistor
Does Radioshack sell better ones?

Note from Gamelver: don't know why, but I don't want my screen to have be able to scroll left/right!!!!

...so, I did some editing

they must

yeah, they sell 10W resistors, which work fine

10W resistors from Radioshack

Wait, I don't see any with the right number of ohms on that search result...

Ok, so they have resistors at higher wattage tolerances. Do they have ones with the right resistance at those wattages?

Oh, and is everything else ok with my wiring diagram? Even if the resistors couldn't take the current, are they at least in the right places and everything?

yes everything else looks fine

Post by **Gamelver** » Sat Jul 23, 2005 4:09 pm

yeah, that's the problem with Radioshack...they suck!!!

....I guess you could get a bunch of 100, 50, and 10 ohm ones and wire them all up in series

....but then you'd need....10 100 ohm resistors, 2 50 ohm, and 5 10 ohm...since radioshack only sells 10W resistors in packs of two, I'd say you'd be better off just ordering the resistors online...

lol or using a car adaptor?

Post by **Gamelver** » Sat Jul 23, 2005 4:17 pm

car adapters only supply 3V, though....and that usually screws up the picture and sound a bit

really?!? that surprises me. i have 3 lm317 (cheap car adaptors rule) so i will rig one up when i go out and buy the resistors!

Post by **Gamelver** » Sat Jul 23, 2005 4:21 pm

so will I

are you making another n64?!

also what wattage resistor do i need?

Godzilla · Post by **Godzilla** » Sat Jul 23, 2005 4:53 pm

Oh well, I'll forget the lm317....

I guess I'll just use a 7805 with three of these:

That'll be less efficient, but at least all of the parts will be easy to wire. So, this is my new diagram:

yup

...I'm continuing my fourth one

...

I'd suggest at least a 10W resistor

also, for that diagram, it may be better to use a 2.5 to 2.7ish ohm resistor...I did some testing earlier today and found that on the 3.3V line the N64 consumes anywhere from 1.2 to 1.5A...because of this, a 2.5 to 2.7 ohm resistor would be better...if it's three ohms, then at 1.5A the voltage drops to around 2.7 or so volts.....WAY to low to power the 3.3V line

Well, I've got a NUS-001. Can I get away with 2 ohms of resistors? What voltage would that give me?
