Desoldering Question

x24 · Post by **x24** » Sun Jan 15, 2006 5:50 pm

I just got a new desoldering iron from 'sourceshack' so i can get back to work at removing stuff from my n64 board. I gor the rest of the controller ports removed then I moved on to trying to remove some extra little metal fragments from the holes around the av out plug..

My question is.. could I just solder the wires from my hip gear screen to the metal pins that I couldnt get out??

I hope so cause I'll probably have my hipgear attached to my n64 by the end of the week..

10 mins l8r I had a Gen3 sitting at $3 with 40 seconds to go and I just got sniped and it went up to $30..

oh well.. finally got my free 3.3v dc-dc converter (I guess) outta the package.. anyone know which pin is for what on it.. I'm tired and too lazy to try and find it at this hour..

and is the Y like object at the other end used for anything?? i probably attach a heatsink to it dont I?

it would be a lot of help if you could help me label this.

with a 100uf cap on out

the metal thing, as far as i know, is just to solder it down to a board, so it lies flat and dosent move. you can cut it off it you want. these things shouldnt get very hot at all, and there should be no need to sink it.

also you should probably have a cap on the input too

ok after reading the 'howwhateverstuffworks.com' site about capasitors.. I realized I still dont understand why I need them..

I also dont understand: Do i need a capacitor with at least 100uf for it or right on? I went to thesourceshack and couldnt find any that were right on.

btw daguuy, according to the pdf, you got them reversed.. according to it its 1-in/2-grnd/3-out

caps can be used to stablize voltages...if something goes under the required voltage for a second, the cap will be charged at the right voltage and ready to output the right voltage until the regular voltage source is normal again. also, I know they're sometimes used in clock circuits, but that doesn't apply here

This is from Search

Where a capacitor is used to decouple a circuit, the effect is to "smooth out ripples". Any ripples, waves or pulses of current are passed to ground while d.c. flows smoothly.

A decoupling capacitor is represented like this

I think that puts it extremely well in simple terms even I can understand!

ok, so its probably used because of the dropping voltage on a rechargable battery right?

could anyone answer my other question:

i little over shouldn't hurt. just don't make it rediculously huge. maybe if you have some old junk you could find some on that
