You don't know the half of it.....but you will :)

I won't speak for BadMouth, but I think the issue may have been that the Walther gun perhaps has a different lens, probably with a bit of wide angle enhancement. I can tell you from experience that the wide-angle lenses can make using the built-in calibration wizard more challenging, sometimes allowing only a tiny window with the gun at a specific angle where the software is satisfied and will allow the user to continue. The software was designed with the simple stock remote in mind, so anything extra/different is outside of what it is expecting. I also found that the numbers weren't really close with an add-on lens, so hand tweaking is probably easier and more accurate in that case.

I was curious about those LED assemblies as well. But I think it's going to be tough to beat the modules BadMouth dug up, especially for large displays. A pre-wired solution using these would be the ideal solution. They seem to be usable at 10' or better (without an add-on lens) and we aren't even using them at full output.

Not yet, but I'm heading downhill pretty fast.
I wanted them calibrated as good as possible to remove that as a factor when judging the accuracy.
They were indeed a PITA to keep aligned.
I also wanted it calibrated as close as possible to the monitor which meant both side LEDs are right on the edge of both being viewable.

I am glad another person is giving it a try. :cheers:
I'd really like to see someone get it all set up with 2 players, Troubleshooter/Demulshooter, & integrated into a front end to show that it works.
I was on that path, but am currently sidetracked by an emergency kitchen remodel.
(If I don't dedicate 100% of my free time to it, it will drag on forever.)

Well that's the plan for me, I wanted to start a thread once I get the hardware sorted and just post configs as I go. Like yourself I'm having a hard time finding free time. I never did get my sensor bar soldered last weekend. Btw you are soldering that up in a series right? That'd make it roughly four AAs. I think I'll use battery power until I get my power supply situation mapped out. The mini solenoids for the pistols came in. They are kind of puny but I'll still give them a shot. As for those mosfets, apparently the most popular module on ebay doesn't actually do what it claims. I finally found a reddit article where it states that while 3.3v will trigger the high side it only does so at about 25% and it takes a full 10 volts to get it fully open. So I'll order new kit this weekend along with my 24v solenoids for the uzis and a power supply beefy enough to run all this mess.

Ok so I'm about to order another round of parts so I got the old multi-meter out to confirm some things. The rumble motor on the wiimote indeed puts out 3.3 volts, and since that's logic level most mosfets should work with it, just not the crappy one I bought. The leds, while still on the board seem to draw around 2.7 volts. My guess is there's a resistor somewhere stepping that down, but honestly, I can't think of what you'd want to use it for besides powering leds. I intend to use the led outputs on the uzi's to light up the bomb/rocket button, the flame thrower button, and the red and green leds found on terminator 2 guns for target lock and civilian lock respectively. I actually just tested some random leds I had in my parts drawer and they light up just fine without any voltage adjustment. I'll take some readings of those crappy mosfets tomorrow to see how much power they are turning on just for curiosities' sake.

BadMouth:
Yes, LEDs wired in series. Basically just made a one conductor loop around the monitor. Even at that low power, I'd be leary of running them without a resistor or current limiting device.

While I am satisfied with how well Lichtknarre worked in my testing, I do wish you'd get it up and running to experience it for yourself before ordering more gun parts.
