24 V. power anyone?
what's better? higher or lower?

I just got my GCT today, picked up on eBay really awesome condition.

I noticed mine came with a Gateway power brick (PSCV450106) that has 24V. 1.875A output. Did anyone get that?

I read some posts on power supplies that lead me to think this thing is pretty flexible on the voltage, someone claimed you cal connect straight to car power at 12 V. (not sure I'd want to without a regulator) and others listed all kinds of supplies between 12 and 19 so far. Here I come, 24!!

I'm planning on taking this out of it's case and mounting it on the jeep dashboard. When it comes to power adapter, what would be best for stability, temperature etc? any considerations?

A second - off topic question: No IDE header... I plan on using a 3.5 hard drive with a power regulator off the ?? Volts input and possibly a solid state relay (or should I use transistors/triac or regular coil relay? what about noise?) controlled by the 5v laptop ide connector.

Anything against soldering one end of the ide cable straight to the pads?

other than being a pain in the butt, you could solder directly to the pads...i don't think it is wise though...first, you are totally stuck if you want a longer cable...you need a "flipped" cable as on the i-openers which i imagine would make the soldering that much more difficult

Stil no opinions on the Tension anyone?

I did indeed solder the 3.5 ide straight to the pads. it was indeed somewhat of a pain (Not too bad really) The order of soldering is pretty straight forward, no flipping, just follow the numbering printed by the pads. I cut every other wire a little shorter to avoid bunching it up. The cool thing is that there is no problem whatsoever with the shield. Now I have an IDE cable and IDE power sticking out of the little side/back door

I made a tiny mod to get power from the 19 (or 12-24) V. and regulate to 12V. I used a Radio Shack regulator, a couple of caps a 5v. Relay (coil since I had one) and a couple of diodes. The regulating part works great, the switching not so great. I can solder but I'm no electronics engineer so I might need some advice.

I'm getting the 5v between ground and the HD 5v. pins, I guess it turns out that as long as the GCT is plugged in the HD 5v. has some tension to it (something around 3v) wich is enough to keep that relay excited is that normal? Keep in mind that I connected both Pin # 41 and 42 for voltage as I saw they're both connected to the power plug in my 2.5 to 3.5 hard drive adapter. Are they supposed to serve different purposes?

The 3.5 hard drive gets both 12 and 5 and it does spin down when I turn the gct off, but the 12V. stays on (therefore does the 12V. fan connected to the same 12V.) not quite what I was trying to achieve.

I'll be glad to post the schematic of what I did if it helps.
