Has anyone used the LCD Top Gun on the Lik-Sang website? Im curious about it, and just wondering if anyone has used it. Ive been thinking about getting the Act-Labs TV light gun, but I saw this one and it looks kinda cool. Any feedback would be appreciated
Thanks

For those of us that are lazy, like me usually, here's what he's talking about:

Looks like a (cheap?) variation on the eReal gun. Different from Actlabs/namco hack in that it completely ignores your tv, meaning it can work on a projector/flatscreen etc... whereas the others needa CRT monitor.
The main issue with guns like this is that accuracy is not as good as lightguns, because they use a usb camera pointed at the gun to detect where its pointing. This makes it very easy to uncalibrate, by saying moving your position sideways by a few inches....
It does mention "2x LED stands" with this gun, which is potentially interesting. Suggests 1) the detector/camera/whatever they use is in the gun itself, and 2) it uses 2 points of reference (3 altogether include the gun) which potentially could make it far more accurate - depending on how good it is at triangulation.
My instinct says this is cheap and not that accurate, but I'd like to proven wrong. Cant find much info on it though....
EDIT: This may be more interesting than I thought.
Just found this site: http://www.hkems.com/product/xbox/LCDTopGun.htm (http://www.hkems.com/product/xbox/LCDTopGun.htm)
It has proper pics and links to the guide/faq/user manual/calibration video. Thoses LED stands look much more interesting - They are thin and tall, and 1 appears to have 3 sets of LED's on it in the diagram, and other has 2. This gives you FIVE sets of Infra-red (which is what it uses) points around your screen, with a infra-red detector built onto the gun.
This is actually quite similar to the technology used in the later House of the Dead series games (sega I think - they had 6 sets of infra red LED's - although they may have been detectors as well/instead).
Potentially, I think this could be very accurate. It also supports 2 player guns - although somewhat bizarelly it states that to use 2 guns you need to remove one of the LED stands. Trying to work out what this suggests about how they are using the technology. It may be there are detectors in the stands too... Anyway, doesn't matter much unless its well made with good drivers. Which means someone needs to test one ;)
Anyway, the last few seonds of the calibration clip (they are playing with a projector by the looks of it) it appears the shots are very accurate on the laser pointer.
Hmm, potentially accurate, vibration, no screen flash, no dodgy tracking on dark areas, no re-calibration unless you move the LED stands. Hmmm....

i guess the thing im curious about is how would the LED stands work with a cab. maybe ill try it out and let everybody know
-
If you already have a cab, you could attach them either side - and maybe cover them a bit. Easier to incorporate them into the build - either side of the screen, mostly hidden. Just need small holes/slits for the LED bits....
Anyway, although I've already got the guncon2 hack working, I've ordered one of these just to play around with. (Knowing me, it will end up in bits as I figure out how it works....)
-
Im new around here(I've lurked for years, just now started posting), but I pulled the trigger and purchased the gun also. Purchased the wireless Guncon2 RGT thingy last week at frys, and it works well on the XBOX, but not so well on my PC. Hopefully this will be better. I think it will look alright on the Centiped cab I am converting.
Ill post a report on my success. I figured $50 shipped isn't that bad a price to try it out.
