Where can I get these parts online?

I've already searched radio shack.com, ebay and google, it seems they are a lot harder to find than I thought.

1. 100 micro ferret capacitor
2. 2.2 kohm resistor
3. 7808 regulator

I need this stuff for n64 portable.
Thanks!

that's farad, not ferret. I can never figure out the american online suppliers, so here are some links on ebay:

http://cgi.ebay.com/3-100-UF-25V-CAPACI ... Components

Well, it helps to use the right terminology.

7808 regulator:

(Or pull one from this $1 board)
(Or make one out of a 7805and some resistors)

No you don't!
Nuh uh man!
You said you were making an N64, well, I assume you're using a PTH08080, hence the 2.2k Ohm resistor...
Well, that's not quite right exactly. (Sorta)

A 2.2k Ohm resistor gets you 3.1 volts, not 3.3.
A 1.8k Ohm resistor gets you a true 3.3 volts.
People say 2.2k Ohm resistor, because it's more common than a 1.8k Ohm one.
While 3.1 volts will work most of the time, it won't work all of the time. (Seriously, it's unlikely you'll have problems)
But hey, I'm a perfectionist.
Why not get a few free 1.8k resistors from me: http://forums.benheck.com/viewtopic.php?t=27753

You say 2.2k ohm resistors, when I bought some at Maplin a while back they were described as 2k2R ohm. Same thing I suppose, but might make it easier to find them.

N64 will work fine on the 3.3v line at 3.1v, 3.2v. 3.3v or 3.4v. So using 2K2R or 2k or 1K8R ohm resistors are both ok. My first N64 system worked fine on 2.9v as I recall, although that was only just ok.

Thats because 2k2R is short hand for 2.2k ohm.

I never got what the R was for. I guess it stands for resistance?

Yes. Unless you are talking to me then its impedance

Yeah, but my point is that they don't say 9U Volts or 500I mA

Well 9V and 500mA is self explainitory.

V = Volt
A = Amp
R = Resistance

shorthand for large voltage and amperage is the same way

9000V would be 9kV
5500V would be 5k5V

how is ohm not self explanatory?

It is but thats 2 more letter to write. Remember if you are in the lab you have to maybe right either "R" or "ohm" a thousand times. Which would you pick

I'd have my secretary deal with it

Besides, what's wrong with just using the good old Omega Ω?!

Secretary? What college student has a secretary?

Also try writing Ω then write R. R is allot faster to write. When you start writing Ω really fast it starts looking weird.

I just draw a horseshoe kinda thing. Like a sideways "C." ᴒ <- like that, but taller.
