well that sucks

wish i had a 1.6 here to test it with. just double check everything is solder correctly. i really cant think of anything else other then the circuit

what it seems like to me is, the pwrok line is not sending a strong enough signal for it to turn on, it just sits in standby mode maybe waiting for a pwrok signal. Thats my guess at least, didn't someone say something about shorting out pwrok or pwron? it was in another thread of urs i think.

ok looks like i was wiring something wrong, i had the orange wires coming from the xbox as 3.3v when they should have been wired as 5v. This fixed the problem and i would like to thank you for helping me make this circuit. I have been running the xbox for about 1 hour and its perfectly stable. I am actually using a 1k resistor instead of the 4.7, will this do any harm or should i just leave it as it is?

shouldnt matter too much but i would try to get a 4.7k some time soon.

bumping this and need a hand

im parts ordering off digi key

i found my needed resistors. but the npn transistors... umm. well
i found NPN silicon bipolar transistors.

but theres a bunch of em id otn knwo which i need :S

www.digikey.com if someone could maybe even snag me a part number for something that would work as Q1

please. thanks

err wait these are the resistors i found.. tell me if yes or no?

http://sales.digikey...temseq=32456334
http://sales.digikey...temseq=32456341
http://sales.digikey...temseq=32456347

or these three?
http://sales.digikey...temseq=32456628
http://sales.digikey...temseq=32456634
http://sales.digikey...temseq=32456640

oh god help im stillt rying to learn how to read this website lol

and this transostor is the one i think is right?

thank you again!!

ignore the above. seems they are mislinking

Mark Morgan · « **Reply #22 on:** January 01, 2006, 02:39:00 AM »

the resistors you need are the ones you would use for leds(just higher values) and you should be able to get the npn from radioshack or equivelant.

sorry bout not responding earlier but im stilll having comp troubles

awesome how about resistors?

thanks!!

theres so many resistors ones like 3 cents each and others that are like 67 i dunno which i need :S

i wasnt sure which way to face them though so im hoping i got it right

resistors have no polarity (either way)

cheep resistors are fine (carbon film)
just make sure the 22 ohm is 1 watt or higher

at http://www.paradoxblue.ca
check over your circuit diagram, the xbox side orange 5VSB should got to the power supply 5VSB (purple ?)

blueinfinity · « **Reply #26 on:** January 01, 2006, 11:59:00 AM »

i dunno this is wut i was told by someone else. thats for the 1.6 psu

i know resistors ahve no polarity. i meant the transistor.

look on the RS package
it should say if not lookup the #

cheers for the help xman

(if you have any left after new years

)

i got some beer elft u can come ahve some of mine

i got a circuit mader i jsut hope my transistor is pointing the right way :S
