Looking for a creative solution: USB bus still powered after CPU is off - Page 8

archimense · 08-31-2004, 03:36 AM

If I didn't run my car for two days it the battery was too low to start it. I have a Mini-ITX, USB GPS/Keyboard/Wifi/Touchscreen.

Opus is releasing any day now a new power supply, 5V & 12V or 12V. From what i understand it's possible it's going to be cheap. That would solve all USB powerdown problems. Also i know this wont help all that already have an OPUS 150W but the next revision is going to be a 200-220W with 5STBY shutdown option, and that should be out in less than a month or two.

Does anyone know when that new PSU is due out?

I just fried my opus 90 (

) and was looking at the 150, but if theres a new one coming out..

200-220W would be cool with the new OPUS.

I have a PC Power and Cooling 100W I bought long ago...

can someone build this for me and ill buy it from them?

ive looked over the schematic numerous times but its hopeless, i have no clue

rando · 09-15-2004, 07:47 AM

My last explanation still didn't help?

aoLhaTer · 09-15-2004, 11:33 AM

rando · 09-15-2004, 12:04 PM

You mean like this post #31 and #32 of this thread?

If you still need help, ask a more specific question.

aoLhaTer · 09-15-2004, 02:00 PM

didnt see that post

cheers

a picture of the actual assembled circuitry would help me understand a bit better i think but the plain english explaination helps also

No it wouldn't. It looks like an ATX extension cable with a relay attached to it and 1 wire hanging out. Everything is wrapped in loom and taped. If want to know what it looks like untaped, check the schematic. The square on the left is your Opus. The one on the right is your computer. The line up top is all of the wires (except the two indicated) that run between your computer and PSU. The other lines are the important wires and they are labeled. The diodes are the the little triangle shaped thingies. The two switches and the the coil are the relay.

thanks

i guess my only confusion is what pins to wire things to on the relay; arent there usually numbers (85,87,87a,86,30) to indicate which pole?

also, whats that rectangle with a diagnol line below the relay?

rando · 09-15-2004, 03:33 PM

As far as I know, not all relays have the numbers. If you buy one at radio shack, it will tell you the pin assignment on the back of the package. You can then just wire it up as I've indicated (plain english or schematic).

The rectangle with the diagnol line is the relay coil.
