I am converting my n64 to use the DC-DC convertors in that one recent thread - I have the 2 amp model. I installed a 100uf electrolytic cap on the Vout and ground leads, but I get a annoying buzzing and noise on my screen.
I took this capacitor off and I got the exact same result - I even tried a few different caps.
Any ideas?
Power supply filtering?

I am having that same thing happen to me! 
and I even used a setup that worked before I removed the N64 from the case........and the metal RF plates..... 
Maybe it's interference from the N64? What screen are you using? Mine is a hip gear. when I turn it on the N64 seems to works fine, but the screen has a TON of lines all over the screen, and all I get from the speakers is weird static sounds. Is that similar to what you're getting?
Also, I tested this a bit jsut now, and when I move my pocket TV near the N64 (about 8 inches away), I can't recieve ANY channels at all, something is blocking them. Odd huh?

if you could give a basic wiring diagram of how your stuff is wired (just like. where the voltage from the sreen comes from, what capacitors are where on your power lines), i could have several electrical engineers look at it. or maybe even i could spot the problem.
as far as i understand, the Dc-Dc converter is switching the power on and off really fast. that is the only way to make the inductor work. so my best guess is that the dc-dc is causing a "ripple" in your main voltage line. there may be a smarter way to wire it all together, or you may just need more caps. put them at each major component, as close to it as you can. see if that fixes it.

ok guys, mine works without the screen just fine. so i think the screen is whats causing this. try a capacitor at the screen? if you hook your nintendo up to a tv with the screen disconnected, does it work?
