Custom Heads Up Display, Possible?

[ISX]

This is probably pretty far out there but I can get info out of my truck's computer (speed, RPM, etc.) and have it on my laptop. Now I know it will be hard, but is it possible to beam it all on to the windshield? Is there something I can buy to do it?

I know, I'm nuts.

There are a few DIY projects on the web of people doing it.
Most seem the simply reimage the screen of a PC/iPhone/etc onto the windshield.

This isn't really a HUD because you have to refocus onto the windsheild - rather than it being projected at infinity so you look through the glass and see the numbers in the distance, but the optics for that are a little more complicated

Almost an off the shelf solution is to get an Android phone, obdkey bluetooth interface and the torque android application. Oh, and your truck must be a 96 and up model with OBDII.

You can position the phone so its image is reflected by the windshield. Works best at night.

Don't have anything too helpful, but if you haven't looked there before, I'd play around on http://hackaday.com/ maybe try to find where somebody did something with a HUD and contact them directly. They have some incredible things that people have made using the most random stuff you could think of. I believe someone got one of those HUD clocks to interface with a computer, that might be a fairly inexpensive setup. Something to look into.

I sincerely doubt it. Usually if a battery comes into that state, it is because of physical changes within the battery like different cells becoming inactive or corroded or something; I'm no chemical engineer (EE actually ), but to my knowledge if your battery is that far along generally only companies that have the proper machinery to refurbish batteries can fix that.
The only thing you can try is doing a complete discharge, letting the system fully drain the battery and cut off, then do a deep charge overnight without turning the laptop on. I doubt it'll fix it though.

It seems to me that all you need is a usb-lcd display like this:

and a half silvered mirror.
