OK cool, so this is totally doable then. Great. So, since I am stupid when it comes to all this stuff, can you break down for me what I would need to buy? I am cool with a crude setup, as long as it works and it runs for at least a few hours. If I can get what I need at Radio Shack, that would be awesome.

The unit has its own power button, but are you saying I should add a power button so that I can BE SURE it isn't drawing any juice from my batteries when not in use?

Also, what is a Gell Cell? Is this a good option? Something rechargable would be ideal...

Thanks for the help,

Bart

I read the PDF and this thing is meant to run off your 12VDC car system (that means you can use any 12VDC source (probably 11-14 is acceptable). I've done some simlar type things and just used a little Gell Cell (sealed battery that I would rechange once in a while). I had an old 7Amp Hour unit that would run things for ever, but anything from 2Amp hour and up should last a couple hours or more depending on size. I put an inline fuse of about 1amp, just incase, and used the plug in connector that came with the adaptor I had for the way to turn it on and off (You might put in a switch?). On the other hand you could just put Eight 1.5VDC batteries in series to get your 12VDC, but I don't think it's as nice of a package (Just my oppinion).

Based on the PDF:
Pin 1 is your +12VDC (red wire)
Pin 3 is your common (Black wire)
Unit draws .8Amps or less

Good Luck, taking those high altitude pictures!

It can be a sealed lead acid battery or Gell cell (instead of the liquid acid it's a more of a paste). I'm not sure what radio shack has. If you have a good sales person they can help you figure it out. If not... Here's a link to a place I find some cool stuff. Here is a picture of the type of battery I was talking about. (You can search around to get more ideas) They have been good to work with if you decided to go mail order, but a local person is usually better if you're not sure what to get.

My best guess at what you need:
1) Battery (2Amp Hour is lighter, but 7 or more Amp Hour will last a lot longer - kinda depends on your requirements for size and weight)
2) Power wires or cable from battery (probably use crimp connectors (Insulated connectors are best choice) that slide on the battery terminals) You may be able to get a cable that meets your requirements and has a connector that can plug into your display or you'll have to crimp or solder to it.
3) Inline fuse (crimp type or may be built into the cable if you find one)
4) An in line switch or just pull the cable off the battery when not using.

I hope I'm being clear enough, without boring you to death. Like I said, a good sales person at your local electronic shop can be of great assistance in either finding a proper cable or pointing you to the parts to make one. RadioShack probably has a good selection of cables or things you could cut one end off and attach something to finish the project (maybe even a used old piece a connector in the junk bin that they would give you???).

How'd I do??

Great, thanks. I will let you know how it turns out. Having a monitor for my video camera will be nice, since its hard to see the LCD from the ground when I have it on the crane. This will make it much more usable...

Thanks - Bart
