Thread: Project NiteVision - NiteMax + HUD + carputer

here's another spanner to throw in the works. I was trying to find an polarised window tint - so to speak

This company makes polarizers in the list the ones that say (white) should be clear the are mostly used in TFT monitors. BUT I can't find any source to but them... I only find gray ones like tinted. I ordered one sheet to play around and some Fresnel lenses for coliminators if needed.

Company that makes them:

From where I ordered the stuff:

Just tried to do some more testing. I cannot get pics for the life of me.

With the long exposure required, the screen just photographs as a mostly white square.

A couple issues, I think you'll need a polarized filter to block your own headlights. Using regular plastic for the reflector, the display washed out almost totally.

If something is relatively close, the headlights drown out most of the view. If I used the 3m privacy filter 90 degrees perpendicular, it worked much better but the view through it gets fuzzy. If you use it the way it's intended, the display is great but the reflector is opaque

wait, how are you having a headlights problem? Are we still on a regular LCD or a nitemax thing? I'm slightly confused on that. I'll play catchup with you guys in a few days (though we're on teh verge of cracking this sucker). Why do we need to filter the headlights? The biggest problem that we saw (wihtout the film, which may be the diffference) was other headlights and pright houses. We drve right up to a car at one point and still saw everything. THen agian, we were in an xB...

Please de-confuse my fragile little head...

I'm a lot further back and lower (I think). Basically if you are to close to something, the pic is washed out. See the poor quality attachment.

I think as has been though that we need some sort of polarizer to block out the light.

Interesting...and disconcerting...

Well I finally have an update to report!

I am sorry I have not been as active a participant in the thread as of yet, but I have been catching up a bit trying to get my hardware working the way i want it to work, So I can get it in the car and start experimenting some more.

But enough of my rambling, the pics will do most of the talking...


Here is A shot of the base of the main HUD part of the setup. This will be recessed down in my dash and there is a black project box that will surround it with the piece of plexi or other window on top even with the dash. I am tiring to get it something like OEM in this regard.




Here are some pics of the camera enclosure i made, it still needs allot of work but it is functioning right now. I have used molex style connections for all of my wiring.






Here is a picture of what is currently not working the way that it should. The camera is on and working but the screen only has its backlight on. I am tiring to figure out what is wrong with it right now. I do not have any of the contrast, gain controls hooked up (that entire harness is not plugged into the lcd controller) and i am wondering if it is related or if i damaged something in the fabrication. All of the connections seem tight, but i have to spend more time looking into it. I also have a second screen and controller so i can replace it if i killed it.




Here is a shot of the connections I made for the main HUD end of the setup, I did a 6 pin connector for the 2 12v+ lines in, ground, and the v, ground and video lines to the camera.




Here is a shot of how long the line is to the camera, it should be long enough to get from my rear view mirror to in my dash. (It looks to be around 10 feet long)




Here is a pic of the rca connector




And here is a couple of shots showing how it has an adjustable angle for the HUD

Low




high




And last but not least here is what the captured image looks like in centrafuse

ok, forgive me as i am playing catchup with what has been going in the last few days myself, I have had so little time and the time i have had I wanted to work on my hardware above

Shotgun, I am going to checkout that magnifier thing you mentioned as a possible lens substitute. I have pretty much decided that a larger image is a must for me, and perhapes it will save me some aggrivation flipping and reversing the image when i get to the step.

I have to say looking though all of the pictures that you guys have so awesomly provided that useing the thin sheet of plastic caught my eye, it really looks good.

shotgun when you are refering to filtering the headlights you are talking about prevention of washing out the HUD, right? not to filter for IR light for the camera????? I think that is what you ment i just wanted to make sure i got you right on that.

I am going through all of the links you guys left. and hopefully soon I can get this in the car and start testing there, where i can be more help to the conversation above

next steps for me:
1. figgure out whats wrong with my HUD screen !@!@??
2. Figgure out what i am going to use as a lens to enlarge the image. (I am planning on mounting it above the screen in the pics above)

Correct, so the headlights don't drown it out. I'm thinking of using polarized film for the hud reflector.

I'm probably going to wait until that HUD glass I ordered comes before going any further.

One problem I didn't think about regarding magnifying the image is that it's a magnifier on your dashboard. Have to think about that one.
