Modern Mallard - NES Zapper upgrade for Duck Hunt (only)

While I respect the idea, and solution for solving the lightgun problem on LCD's, there are two things I don't like about this project. 
1. Too expensive for only Duck Hunt.  This KS will ultimately fail because the cost is too high for just one game. $129 for a DIY install is ridiculous. If he manufactured his own lightguns with this device pre-installed, eliminating any work on the consumer-side, then I could see justifying the price. But still, for only Duck Hunt? 

2. Destructive installation.  Cutting wires in the zapper, removing the original lightgun board is something I wouldn't want to do. Destroying the cartridge case, and having to install a romhack board is also something unappealing to me.

I followed this one while I was away.  Whatever solution they came up with must be overly complicated or something because the NES zapper is much more simple than a traditional lightgun and in theory it should be fairly easy to rig up some sort of solution without resorting to rom hacking. 

Unlike the serialized data of the gamepad on a nes, the zapper just uses the extra two pins on the controller port for raw inputs (active when low).  The trigger state is always sent, regardless of whatever the gun is sensing.  The light sensor trips whenever the gun sees white.  That's literally it.  There's no scanline crawl counting or anything like that used to determine the gun's position and therefore it isn't crt dependent. 

What keeps it from working is the fact that whatever light sensor is used in the gun can't detect white flashes on a lcd screen.  So all that's needed is some type of light sensor that can determine if white is drawn on a lcd that's fast enough to trip that input as soon is white is detected.  Now that might be easier said than done.... perhaps such sensors are costly and/or laggy but with motion detectors as sophisticated as the Kinect around surely there is a camera that can detect white squares on a screen.

DAE member turning up the brightness on your TV or pointing the zapper at a lightbulb to cheat?

I remember that wouldn't work because the Zapper checks for a dark screen before checking for light. Mixed results could be had by using a strobe light but the timing had to be just right.

Also the problem with LCD isn't brightness, its input lag. By the time the white screen gets shown on screen the Zapper has already registered a miss. I talked about this in another thread.

The lag on the video display should be minimal.  That sounds more like a 240p issue than a lcd issue.

19 hours to go and not even 10% of the funding needed.  Saw that coming...

For one game and the effort involved was never going to happen.

No way would I be destroying any of my old NES stuff to play duck hunt.

Yeah you MIGHT be able to get people to buy it if it came with a cheap Hyperkin zapper shell and the add-on was designed like a game genie and supported all games.  Even then, for me at least, 100 bucks to play a little over a dozen games, only a few of which are actually fun, is a bit steep.
