Hey guys, I'm going to make the aftercooler -(http://www.rbjtech.net/xbox/aftercooler/aftercooler.htm)
I'm looking for cheap parts instead of buying packs of 100 for my first one as a test.
If you have any of the following, please reply:

NE556 Timer - 14pin
14 Pin DIL Socket
BC549C transistor
1 MOhm variable resistor/potentiometer
1N4001 diode (x3)
1N4001 diode
5v(6v) DPDT Miniature Relay
10 Way PCB Socket
10 terminals for above
10 Way Plug
PP3 9v Rechargeable (170mAh)
18 ohm resistor

For free would be great (remember it's development of the xbox) Very Happy

Happy to make offers.
Cheers,
Deers

That website's horrible. It's list after list and I'm too pathetic.

Thats where I bought my stuff for it.

why not just attach a timer to the off button? after you are done playing, go back to dash, then have a 5 min timer.... plenty cool by then.....

Hm, I like my homemade 555 timer aftercooler circuit better Rolling Eyes

If you're willing to wait a week or so I'll probably be able to sell you a built circuit on a custom PCB for less than the parts for that one...
Or at least give you the schematic with more common/cheaper parts.
I'll let you know when I get the normally-closed relay, that's the last part it needs.

That will be great!

I'm visiting family and there's a big electronics supply shop around here that I'll check for the relay. In case they don't have it, does anyone know where to get a 12V or less normally-closed (small) relay?
Edit: Nevermind, I just realized DPDT relays have a NC and a NO pin and I could just use the NC pin.

I got the relay I needed, and I got the parts to make several of these circuits. Would anyone be interested in buying one assembled or in kit form with a PCB and all components (and instructions)? I'm not looking for a commitment, I want to know how many boards I should etch just in case.

I'm interested in building my own and everything. Or the cheapest way possible. Very Happy

I'm failing at my attempts to etch a board for the circuit, but it can be made pretty small on a prototyping board like this one http://www.hndme.com/productcart/pc/viewPrd.asp?idproduct=1606&idcategory=79
Here's the schematic, the two things on the end are relays, one to trigger the 555 and the other to put power to the fans. This would be wired to 5V standby with the trigger pin wired to a switched 5V point. You put power in one of the OUT points and the fan lead to the other.

Let me know if something doesn't make sense. If I ever figure out how to get my boards to etch properly then I can sell you one pretty cheap, but it might be a while...
