Hey guys, sooo many pages to read through... Did anyone figure out what material to use to place on the windshield to reflect the image properly?

YESSSSS!

Guess what fellas, IT WORKS! This is way to cool!

Basically, 12v power and ground, composite low and high. 4 wires and I was able feed the image into my monitor. All those other wires are just GM fluff. I used a PC power supply to test.

I was doing some fun-with-thermal-camera stuff tonight like putting my hand on the wall and watching the prints fade, checking out the heater pipes in the house, etc.

Plus, normally it is set to display white=hot, black=cold. If you reverse the signal wires, it goes the opposite way. Might be handy for something, not sure what though.

It also frees up the HUD unit to do that graphic LCD idea, which will be a summer project for sure!

This is gonna be FUN! Now, time to go hunt down the cat...

I found this site from hackaday.

Anyway, I work at a wholesale auto glass warehouse (manager) and I have had some experiences with HUD displays in vehicles. More importantly, the glass and what is in it. I didn't read the entire thread here, but I am assuming you folks want to reflect the projection on the windshield properly without it getting washed out or projecting light through the windshield so that other drivers see it.

I know that there is an 8x8 laminate sandwiched in the windshield that has different reflective properties than the rest of the laminate in the windshield for cars with HUD’s. It is transparent at one angle but reflective at another. I will call our manufacturer in china and see if they can give me a product name for this laminate.

You could probably mount the laminate on the interior side with a good commercial adhesive and get quality results suitable for daily driving.

That is if you folks are still working out this problem or the project isn’t dead.

Let me know

And hello to all, Nice forums.

When you get that baja, give me a shout out

I think he ment that you take out the backlight, leaving only the lcd plate, and put this betwen a bulb and the windshield.
Same principle as this:

At least that is how i think we can sovle the brightness issue.
As for the size, i think we have to look to the camera-lence tech, or simular.

Yes that is actually exactly what I was talking about. Haha good pic. Looks like that idea is obsolete now though?

BTW Genesisfactor the Baja fell through, so all I got is my Yota for now

Hi, I'd like to know. I think it's made by Dupont (though I can't recall the name at the moment). I believe it has a slight wedge shaped cross section that cancels the reflections.

I was under the impression it was mfg'ed right into the glass though. Do you think some type of optical grade adhesive would work?

Yes and No. It is installed during the process but it isn't actually inside the glass. Two pieces of glass sandwich a laminate. Kind of like making smores

I have a calendar that shows the process next to my desk. It's all done in a clean room at the factory. That being said if one were to just get the HUD laminate then you could mount it to the outside of the glass versus between the two sheets of glass that make up the windshield and achieve the same effect as a standard factory install.

Anyway waiting on an email from the manufacturer about the actual name of the material and where to buy it from.

Genesisfactor · 01-15-2008, 01:07 PM

lol, i had to go back almost a year to remember what the baja was about lol.

hehe, just saw my name and was like "huh?"

oh, on that note,sharkbite, i'm doing another project with a projection based system. cree Q5 Xlamp LEDs...look into them, okay

I don't want to hijack this thread but I have some stuff for sale if somebody is thinking on doing this.

Thanatos.

nice!! i cant wait to do it!

I found another NV camera on e-bay, looks like it was dropped or in an accident, but for the right price, who knows! Also, I think they mean it was a 2000, since they didn't put NV into 99 Devilles.

Here's the link, let the bidding wars begin!

Got some news about the windshield display properties today, specifically for the Cadillac but it might be useful for other cars.

Had a chat with a guy who was part of the NV design/implementation team for GM about 7 years ago, right around the time they were installing the NV cameras hot and heavy.

Basically, the factory stopped making "special" windshields for the Deville in 2001, and went a different route altogether. They actually tested batches of completed windshields from their suppliers at the factory. The ones with a higher reflectiveness were reserved for cars ordered with NV, and the ones with a low reflectiveness and leftover high reflectiveness went into the cars ordered without.

The difference was about 1-1.5%, not much, and well within tolerance. Standard glass reflects about 3.0% per surface, the ones that were considered "high" were 4.5%+ per surface. It saved them ****loads of money, and did the job of displaying the HUD infor just as well.

The reason I bring this up is for you guys playing with the nitemax and such, you may not need to get all involved with filters and tints, YOUR glass may do the trick all by itself. At least give it a shot first...

Also, if you have a few grand burning a hole in your pocket, there are 2 auctions running right now for the Caddy NV setups.

Just thought I'd share that tidbit of info.
