FREE DC-DC CONVERTERS!!!

I'm adding this thread to the N64 info sticky, since it's a great cheap (wait, no, FREE!) way to get converters

i just ordered a 3.3v 2a reg, hopefully going in my DC

ill buy a 5v reg somewhere (or find something with one in.)

then a 12v supply= treamcast, with a ps1 screen.......

you can get free 5v switching regulators the same way from that site...

aargh! I filled in my school as my company and the dc-dc converter was sent to my school! When I went to get it they said: "What is this? As long as we don't have to pay for it it's ok." Which was quite embarassing.

I used my school, but it's going to take another month to get here.

Yay I got mine today! It's probably 1" by 1" and has 3 pins, Im thinking its the same setup as a regulator (input, ground, output) would that be correct?

yup, that's the one

Whoops!

Thats not quite right! You see...

If you connect it like this:
1 2 3
Input GND OUT

then it outputs the original voltage.
But if you reverse the two, like this:

then I got 3.4V. So before you wire it up I advise you to check it! (the writing on the converter is the same.)

that just depends on which way you look at it

. if you're looking at the circuit board side, it IGO

I got about 3!

Hoo-ray for freeness!

dude. please do not do that. unless you actually needed 3 (somehow i doute it)... but still.

a lot of peopole have ordered these. id like to keep the volumes down a bit... if they do realize whats happening, they wont be happy.

yeah, they might catch on

.....of course, I'm not helping, by ordering three, but I really do need them, for three different portables. (and no, you can't know what they are!! 'cept they all use N64s, and two are technically already done

...)

Well... You can't use the 5V converter for replacing the 7805's on a PSone screen to get better efficiency. Whenever there is a bass or something loud on the speakers, the screen gets all distorted. It outputs a steady +5v output even when the speakers are going loud, so a voltage drop is not the problem.
I even used the optional 1 uf ceramic capacitor (I had to use ten .1 uf caps in parallel), it made no difference at all.

Here's my thread about it. If you have any ideas on how to get this working, DO TELL!

I also got a battery meter!
