Yup (On the ultra CCDs). That's why I got 4. Two are for the car. One is going to replace my SAVV reverse cam. The night pics on that are way too noisy.

An error I made earlier, when I thought I was outputing 60hz vertical to the screen, powerstrip was still controling the refresh rates (windows rates were disabled) so while I thought it was eating up 60hz, it was actually taking in a touch under 30.

Still scrolling. :P

(Notice how readable that text is?? 640x480 on a 2.5" screen, and its actually readable! (The insanity!)

Any luck with this since? Did you try the sync circuit?

fun time...does the LCD itself have this feautre available to play with? How about that PSone screen, does it have tha ability?

The mirror image? The nitemax lcd board does it (it's somewhere buried in one of the threads), the standard nitemax CCD cannot.

The PSOne screens? No idea.

- Any of the CCDs with 2x Zoom can mirror the video output.

- Any of the NiteMax LCDs can mirror the video input.

- The original NiteMax B&W CCD is the only part that can't mirror anything.

So as long as you've got a 2x Zoom CCD or the NiteMax LCD somewhere in your system, you've got mirror capability.

Lenses?

dtran01 · 04-26-2006, 05:33 AM

We now have 10 lenses total ...

I am assuming Mark is still working on the negotiations. (?)

Mark,

Do you have any LCDs left?

Thanks,
Dan

Yes, too many to count.

Basically the status is still this: I have dozens of some items and hundreds of other items necessary to build complete NiteMax cameras. I don't have ANY of the internal Power Supply Boards.

Proposed Lens

It looks like the best price I can get will be $15 delivered to individual members. (Which is less than the $20.49 by going direct through this seller.) I am assuming I can re-ship them individually by first-class mail. International destinations will not be so lucky. Hopefully I can add them to a larger order so that the ADDITIONAL cost of shipping is nearly zero for the lens itself.

I sure wish I had a VGA cable to cut apart!

Does anyone have a dead VGA monitor that they are interested in trashing? An amputated VGA Cable would sure be handy right about now.

I have a 4' VGA cable I don't need - it's yours if you want it.

I'm going to Radioshack today and pick up a vga connecter (they're like 3 bucks)

Quick question on experimenting with VGA, going by this post...

Is this what I have to do?

- Apply 12v DC on JP1 Pin 11
- Attach Ground to JP1 Pin 9
- On the pads near JP1, connect a 5k Ohm potentiometer between the "5v" pad and the "Gnd" Pad. Connect the center (wiper) pin of the potentiometer to the "Brt" pad.

- Put 5v? to JP1 Pin 3
- Connect RGB inputs to JP1 Pins 6,7,8 respectively

Then try and figure out sync.

JP1-3 Selects between NTSC and PAL Composite Video format. This is not the correct pin to select RGB mode.

JP1-4 Should be pulled high to +5v to select RGB Mode.

You'll need to apply HSYNC and VSYNC in addition to what you've listed. Right now, the only thing that works for sure is to apply a Composite Sync signal to the Composite Video Input on JP1-5. (Your VGA output almost certainly DOESN'T have Composite Sync available.)

Pending the outcome of my experimentation, there's a good chance that a minor mod to the LCD Controller Board will allow the individual sync signals that the VGA connector outputs. It hasn't been done yet, but my feeling is that I'm close to having a working solution.

Thanks Mark. I meant JP-4, was tabbing too fast between the chart and the post.

I was reading through the Sharp chip datasheet the other day and tracing circuits on the board. I see how you came up with the first guess at sync.

One thing that has me wondering is how it stops rolling when he hit's the gain button. Got me thinking about the RGB amplification adj pin on the sharp.

I'm guessing that cranking the gain up high causes enough noise internally to make the sync input THINK it has found sync. You can synchronize to one of the color signals at times, but it's completely dependent on the pattern of the image being displayed. It's a curiousity, but I'm not putting too much importance on it because I've seen this kind of thing before.

All we need (I think) is to feed the Sharp chip a satisfactory Vertical sync pulse and it should work. The question is how to do exactly that with the least amount of modifications to the board -- so mere mortals can make the mod without specalized equipment or skills! (I'm convinced that the clever little XOR circuit proposed somewhere will work, but It's more than I care to do because it's not convenient for most people.)
