I like sushi

don't see the attraction myself

you don't SEE the attraction

or you don't SEA the attraction?

It didn't. Probably because I haven't bothered with it. It runs for a few min on my 9v 500mA AC-DC adapter w/o the IR.

I would still like to know if it has reverse polarity protection.

ask in the nitemax thread..

This basically turned into the nitemax thread

I finally looked closely at the Power Supply board. There's a diode in series with the battery terminals that will block current if voltage is reversed. However, there's nothing similar on the 9v Adapter Plug Input. If it survives reversed polarity, it'll be only by luck and not by design! The doide will also keep the 9v Adapter Plug Input from charging the battery when they're both plugged in.

Here's the deal, I have all of the parts of the NiteMax except the power supply board. (The one without reverse polarity protection.) The NiteMax has the following functions and parts -- they can be easily assembled with a 12v Power Supply of your own.

(1) The Power Supply accepts 9v DC to 12v DC from a bettery or a Plug-In Adapter. This supply provides 12v DC to power the CCD Camera Board and 12v DC to power the LCD Controller board. This board also provides an push-button adjustable voltage to drive the IR LEDs and another push-button adjustment to adjust LCD contrast.

(2) The CCD Camera Board accepts 12v DC and generates a Composite Video Signal. Feed it 12v and conntect it to a video monitor of your choice!

(3) The LCD Controller Board controls the LCD Module. It accepts 12v DC and a Composite Video Signal. It requires a 5k Ohm potentiometer to generate a variable voltage for LCD Contrast. Attach the pot, feed it 12v and an NTSC video signal and you've got a tiny Color Video Monitor!

(4) The IR LED Array lights up the scene with 870nm IR light. Feed it a variable voltage and you'll get a variable output.

All together it's a NiteMax. With individual parts and some creativity you've got all of the same capability as a NiteMax.

Also: There are people selling NiteMax cameras on eBay at times. You'll find that the prices vary between $50 and $100 as long as there's not a bunch of competition for them.

Good to know! thanks for the straight reply

call me doctor frankenstien. look what 24hours does. The world is right again...and 0l33l got his answer, so everyone is happy.

And me, i' just waitin for a few people to pay for the nitemax's i bought for them...otherwise i'm going to be out of $100! or $75 and a GPS...well, technically, when my car is better its all good.

Oh, shotgun, what's the status on those lenses. i have a major use for them: Day/Night sniper rifle for my PB gun, complete with LCD targetting system!!
