Duh, fixed.

I've just been a little fascinated with the whole DIY 100" projection TVs anyway, but I thought maybe this lens could come in handy for something else.

Maybe I'll rig it to the NiteMax in the grille somehow and be able to see a bumper sticker a mile away!

Seriously, I am thinking about magnifying the 2.5" LCD to project on one of those holopanels or through the holopanel on the windshield. This may or may not be the set up I finish with, but what the hell for $25.00.

But how do you do it using htat lens, that's what my mind refuses to process. For $25??? I have $25...tell me how?? Details my educating friend!

I got a bunch of nice projection TV lens for under 10 bucks each at electronics goldmine, so good deals can be found.

Though that lens looks nice due to it's size. The ones I have are rather large. As far as using, just stick the lcd behind it and focus. You'll really need to replace the backlight with something brighter though.

This is just one of those lenses sitting in front of a camcorder viewfinder.

The lense itself.

Just like you would do a home theater projection set-up, only on a smaller scale. Similar to an LCD projector for PowerPoint slides, etc.

Reflector -> Light Source -> Isolation Plate -> Fresnels -> -> 2.5" LCD (or those real little ones we saw a few posts back) -> Projector lens -> screen (windshield, holopanel, passenger forehead).

Some fans for cooling...

The motors should give me an infinite amount of focusing power on the display side. Not sure what type of hookup is behind it, going to see when I get it.

My theory is the night vision display doesn't need to be super bright, so a lower wattage bulb emitting less heat is possible. Second, for the cops, I think the smaller (3") light source pointing almost straight up might be a little less noticeable than a 5" or 7" 400 nit monitor. Might be able to work some magic with mirrors too.

If that doesn't work, then I can point it towards the hood, aim it at a mirror, and display a rear holo panel under the speaker grille, facing me. A little ABS side shields would prevent light from escaping...

Like I said, all theory at this point. Cramming it into the dash is another hurdle.

I suppose I left out a little bit

The 3m privacy film is pretty good for hiding the projection source itself. (except from directly above)

I just thought id tell you that i've been doing this for a while now for pretty cheap too.

I've been using a PDA as my HUD and a small piece of tint (i've removed it now want to find a better way)

The way i did it was have the PDA hooked up to the usb sync cable which powers the unit and connects it to the computer then i've just been using a small program which turns the PDA screen into a second PC monitor.

All i do is have D3 load up on the PDA screen and let it run from there.

The PDA runs like a second monitor but it has VGA quality so i can actually see the text on the windshield.

I haven't been on here for ages so i didn't even see this thread so im sorry i couldn't offer any help from my end.

All i have is a PDA with Sidewindow loaded up which installs a driver on the carpc then lets u drag and move windows from the 7" monitor to the PDA screen

A simple easy and very thin way for a screen in the dash

Hope this helps u guys out somewhat

Is your screen transparent, ie have you taken the back off? And I'm guessing you can't adjust where you focus on the screen with that solution, ie. you have to adjust your eyes to focus back inside the car on the screen?

Genesisfactor · 08-15-2006, 03:31 PM

we did it

. I didn't want to buy sidewinder, but yes, its a great and cheap way to do it (i have a few pics). We're working on the "better way" though as we want to remain in the legalities of the state. But you are quite right and it looked awesome. I liked iGuidance on it. In Night colors, it looks great. Read the 3rd or 4th page for a few pics

. i didn't use tints though.

This porject, however, is trying to use the NiteMax cameras as a whole, which provides us with a CCD, and a VGA capable 2.5" lcd, which cna be seperated and used independantly. Then we kept taking it a step further.

I would like to see pics of your goods man. I want to see where you put it.

jammy, the idea of the HUD is that its see through. Its like focusing from a car way ahead of you to a car infront of you. you still see everything, but you're focusing on something in particualr. Its pretty safe if done right.

jammy_basturd · 08-15-2006, 03:38 PM

Lol, I know a HUD is see through, I hadn't noticed he'd used that word in his post. So for a moment I thought he was basically just putting the PDA on top of his dash.

I'll go home now.

lol

If your using it for what should be on a HUD (guages, nav) and it doesn't interfere with your view, even unfocused, I think it's probably safer than a regular cluster.

Either way you're moving your focus, only with an unfocused HUD, your eyes have to travel less from the view ahead.

Well my carpc isn't in the car right now but i have a O2 XDA IIs (a smartphone aka pda and phone)

And i have a small leather stand i made which just sits on the dash behind the gauge cluster where the phone lays on to project the nav on the windshield

I don't wanna cut up my dash and as the PDA is my phone a stand is more useful for me than getting a old PDA off ebay and using that altho i might go that way sooner or later

My PDA still sync's with the pc while i use the PDA's screen as a second monitor and i can recieve calls with a bluetooth headset.

I can install the software on my desktop pc and take some pics to show u D3 on the PDA screen and any other window i just gotta find the damn camera only camera i have right now is on the phone and i can't use it lol

NiN^_^NiN · 08-16-2006, 06:45 AM

Ok i can't for the life of mr find the digi cam so i took the webcam out from the car to show u.

I just used mapmonkey to give u an idea on what D3 would look like im sorry bout the brightness of the screens.

A note tho is if you start mapmonkey up when the PDA is set as a 3rd screen in my case mapmonkey will start up at the last position so if its on the PDA screen it will start from there

Least the video shows u how easy it is and the speed of the PDA's screen is good i can watch a video altho it seems that every 10 secs the screen slows down abit then goes back to full speed for movies for mapmonkey or viz etc its fine

Enjoy sorry i can't show it to u from inside the car right now how its normally hooked up.

NiN^_^NiN · 08-17-2006, 08:34 AM

Attached is 2 pics from my HUD in the car

My camera is a piece of S@#$ i swear

The images are of D3 in night mode showing the street the right way around (i did remove the tint but with how bad the camera is it wouldn't show the text anyway).

If you look at hud3 it is a crude drawing of how mines setup

The PDA is at about a 45to 60 degree angle and the mirror is on 95 to 110 degree

with the PDA up so high it stops the windshield seeing the reflection of the PDA but with the mirror back that far it reflects the image from the PDA and cause its a mirror it flips the image to display the text the proper way AKA u can read the streets and the GPS will move the right way.

The mirror i've used it a flimsy plastic with rounded edges (i don't want it flying off the dash into my eyes if it was a glass mirror)

The good thing about this is the display is CLEAR as it is VGA not composite. It's the right way up so its readable and the mirror stops the view the PDA screen from shining outside so if i cop drives past he wouldn't see it.

I used foam and leather for the stand and plastic mirror just incase i get into a crash and it goes flying the only thing that would hurt is the PDA which im working on if i wanted a carpeted dash cover that would hide it all and make sure the PDA doesn't go flying.

If you look at the screenshot of mapmonkey you can see that the text is actually the right way around on the windshield

Genesisfactor · 08-17-2006, 12:49 PM

and you get no double image from that?

DOn't worry, i hada good camera and it ouldn't capture the holo image.
