Looks a little big for a dash, but nice.

i always thought they had transparent LCD overlays, i didnt realize all huds were projected

What about something like this?

nice find! easy to get multple display this way. I wonder how much video a usb bus can handle before it slows down

Hey mark or shotgun, have either of you figured out how to get S-Vid to work or should i stick to RCA? I'm about to take apart one of the cameras just to see it work

Also, mark, i'm getting inconsistent powerons off the car adapter. What could be causing that? When it works, it works great, when it doesn't it doesn't. The sad thing is that the image it produces is alot cleaer than my eyes can see...and the nitemax has been a very useful Ops tool

Haven't spent any time on it as of late. Honestly, at that resolution, I don't know if you'd see any big difference from Composite vs VGA.

I did order any auto-iris lens to hook up the the Ultra Color CCD. Hopefully that will help with the night shots.

Found some cheap TV projection lenses at
Electronics Goldmine

Figured they were worth a shot for $5. I'll let you know what's what when they arrive.

Alright, so I'm waiting on my new lens with auto-iris to come.

Then I remember that giant compustar lens I have. I went to hook it up and apparently had the wrong datasheet. This lens has it's own iris circuitry built in instead of the camera driving the iris directly. So you feed it power and video and adjust the knob to determine compensation (anywhere between peak and average intensity.)

What a difference. Here's two short (~500k) videos showing the iris turning on. This lense is F1.2 so the blinding effects are even more noticable than with the other cams. As you can see, the pics with the iris fully open are fairly useless. As an aside, the lamp is not that bright, those bulbs are only 15w.

vid 2

So if the iris of the new lens being driven by the camera is similar, then that and a polarizer should be a giant improvment.

update
As an aside, when I was testing this earlier looking outside, I shut off all the lights (to kill the reflection on the window) and while toggling the iris, a alligator clip came loose and shorted something. Only I didn't know it.

In short order, the picture went out, then in the dark I saw little blue sparks and then the wires start to burn. I fumbled for the plug in the dark and yanked.

My camcorder was unscathed, but judging by the smell and scorch mark on the board of the nitemax, figured the nitemax, and probably the electronics of the auto-iris lens were toast.

Everything survived

, let's hear it for good engineering.

lol don't you hate it when little aligator clips slide off.

not up to speed with this thread yet but wanted to say:

1. good stuff guys...i have been doing a HU disply on the glass infront of my speedo etc. It is only 1" high so the curvature does not cause a problem. However i have to use a mirror on the bottom and relfect back up so I might try using a thin sheet set at an angle behind the glass instead.

2. Be careful with LCDs left pointing up at your windshield in sunlight as the UV will destroy the lcd panel over time. i was planning on having my nav screen pop up out of the dash but might experiment with a hud style.

also...i need a ****ing nitmax camera...or something similar any suggestions/links?

As far as the cameras, I think Mark still has a lot of the Nitemax components. The only thing he doesn't have is the power supply board, but that's easy enough to get around.

For instance, all the vids I've been posting, it's just one of the Nitemax Ultra color CCDs

Finally got those projection tv lenses from Electronics Goldmine today.

Pretty sweet for $5 a piece. I grabbed two (in case I want to make a projection tv.)

They're pretty big, I think it's a triplet lens. But not so big that it would be impossible to fit in a car.

So as a test, I took my camcorder (which has a screen the same size as the nitemax) and went into a dim (not totally dark room).

Even with the puny lcd backlight on the camera, easily could project it to about 15-20" image on the wall from under two feet away

shotgunefx · 05-24-2006, 02:17 PM

A few pics...

The lens. Appears to have a polarized coating on it.

Now for the following shots, keep this is mind, the lcd is on a tripod, but the lens and camera are hand held. With no flash, the long exposure and my shaky hands, very hard to get a half decent picture. Also I'm projecting it onto a bumpy, flat-coat painted wall.

This is the lcd projected to about the size of a 32" TV. Keep in mind too, it's just the ****ty lcd led backlight illuminiating the LCD

i have $5...time to go shopping! How much plus shipping?
