Excellent, glad to see the HUD has come back to life!!!
I was just going through a box of old carPC stuff this morning, and found a few of Nitemaxx cameras, CCD boards and IR boards, the monitors and lenses we were experimenting with, all kinds of notes, formulas, etc. What timing, huh?
Personally, I decided to go a different route and was able to get a factory thermal NV camera out of a 2002 Cadillac Deville, as well as the hud, wiring harnesses, interior panels, switches, even the grille! Since I had an 02 Deville, and the panels were the same color, I figured easy install and instant NV. There is a thread on here about my follies I think
As always, the few hours I needed to install this crap never were available, and I just sold that car a few weeks ago, without all the NV stuff of course.
My new goal is to now put the NV camera behind the grille of my 2006 Escalade. Since the camera just sends out a composite signal, any basic projector or monitor will work.
I have sucessfully used 2 of these pico projectors (borrowed from friends, not too long ago) for a few trial runs on some ideas. They seem to work great, if you can accept the limitations they have by nature and don't get your hopes up TOO high yet.
My first test was projecting an image on the windshield exactly where the HUD would be from under the top of the dash. I can't remember which projectors we used, but IIRC, it was the top end AXXA laser $600.00 one, and the other escapes me...it angled, cinnamon or something?
The Escalade windshield is as flat as a board there, so no major ghosting or film was needed. Some film would help to crisp up the image, but for NV and deer and pedestrians, etc, that transparent look is perfect.
The other test I did was for the PC image. I have a piece of some back-projection trade show panels, and mounted / calibrated a USB TS to it. Worked perfectly, and was bright enough for gov't work, but would be a little tough in the car as-is. I put it down by where the clock is on the Escalade, similar to this pic by Nexon just today 2004 Cadillac Escalade Center Console Monitor Fab, DIY Help Inside!! 73 Pics =)
If it was up higher, and in a shadow...maybe. The other concern is the throw. These need to be farther back than you think for a 7" or 8" image, the shorter the throw smaller the image. For a HUD you may need to get mirrors involved, which works too.
I will follow this thread and help when I can, GL to all!
On a different note, for some interesting reading, check out this EHUD http://sites.google.com/site/ehudv2/ I spoke the the guy who made it via e-mail a few times, nice job on this project.
Another note, EC Glass (electrochromic glass) technology is getting cheaper and in the hands of modders too. Might be a nice alternative to film, expecially in small sizes. Info here http://www.sage-ec.com/pages/faqs.html
TO THE FUTURE!!!
