Hi all. New to the forum. I have a 99 CRV and I want to stash a PATA hard drive in the lower console (the one that swings down) for MP3's. My stereo head unit has a USB port in the front in which I'll plug into. Nothing fancy here, except I want to know what's the best way to power the hard drive.
I have an HD enclosure that'll take normal AC voltage. Should I take it apart (nice because I can mount it to an HD bracket that's mounted to the lower console) and use a small DC to DC ATX PSU ($30 or so) using only the PATA connectors to power it? Or should I just get an inverter ($30 or so, can get at Home depot) and reroute my cigarette lighter down there?
Check the output on the AC adapter. It's probably 12vDC, but could be some other voltage.
If it outputs 12vDC then you can, as coreyspeed suggested, use a 12v regulator (not a converter, since there's nothing to convert) such as a Carnetix P1260, which is not manufactured any longer.
There used to be 12vDC regulators available through thge mp3car.com store, but they aren't there any more...
Mpegbox.com has them. Check the DSX12V or DSX12VD.
power supply say the DSATX? Any ideas on price on this ? Can I hook it up directly to my car battery (i.e. does it act as a regulator?). I was looking at the picoPSU-90 (less overkill on power needs), but it needs regulated power as input.
Carnetix model with a 12v primary and 5v secondary would better suit your needs. I think the P1290 is right up your alley.
The DSATX is an full-on ATX-compliant PSU, meant to be a direct replacement for a desktop PSU. It could be made to work, but it's a kluugey solution, at best.
However, it's not going to work, since the OP needs both 12v and 5v.
power inverter for $20 from walmart make more sense?
I don't need any fancy features such as power monitoring, ability to survive car starting, etc. It's just a hard drive and I plan to turn it on only when I'm going to use it.
