Teeny-Tiny Monitor

We're talking about standard LCDs for displaying the OS X desktop, right? If you're looking for a consumer-electronics style LCD (as for a secondary display), those are easy to come by but you may have a bit of a headache getting them to work with Macs.

It sounds like all you need is a ~10" LCD. You can Google for models, but if you want touchscreen capability, you'll probably need a USB-Serial adapter, because most touchscreens for home use have DB9 connectors. Resolution will also be a problem, as most of the reasonably-priced small displays are going to have resolutions not more than 1024x768.

What kind of budget did you have in mind? In all likelihood, you might look for a small LCD TV, ensuring a VGA connector (or DVI if you're lucky).

 

There are quite a few with USB connections on eBay now, and they just need a generic touchscreen driver. These can be fished off the web without much trouble.

 

Not sure you'll find the right model you need here, but it's a good start: mp3car.com.

 

One problem you'll have with any car-based products is that they are wired for automotive power (+12V DC), so you'll have to rig up a converter, especially if you're leaving the mini intact for the installation. Also, they rarely have physical power buttons, so you'll have to wire in a switch.

But again, you'll have trouble with resolutions. Lots of car displays these days are widescreen 800x480 displays, which would be almost worthless for using a computer.

With a better (post-tea ) look at the math, you're looking for a 9" LCD (4:3, naturally, given the constraints of the case). An 8" LCD might fit as well, but could require a bit of creative bezel work.

 

512, you mean like 4:20 or, no.... anyway

The 512 Mac Preservation Forum has an article on someone who did this with a G4 Mini... Check it out:
