Did a little testing tonight (rotated my camera 180)
I find that the accuracy is not sufficient to play with.
it seems smooth, but I find that the leds being offset outside the frame of the screen, makes it so that its not scaled 1:1

JayBee, you asked how you could prevent people from earning money off of it.
Well, you can release the project under creative commons CC BY-NC-SA license

Did you put the LEDs right in the border of the screen or on the outside border? For me it's extremely accurate, more than any solution I tested even real light guns on CRT ;)
But I had to get LEDs good enough to avoid any flickering (and so loss of position).
Creative commons won't prevent anybody to use my code, since there is no way to check if they are using it unless they share it too :lol

I run mine at the lowest voltage that is specified and works at 3 meters distance.
I bet I could go even lower ;D

i found these OSRAM SFH 4546 : High Power Infrared Emitters 5mm 940nm 130 mW/sr 1.5 V 100mA 40° deg 12ns
will they work?
and what resistance should i use for these?
always 56 ohms 1/4w?

Thanks a lot guys for support :)

@JayBee on my cab i will have to put the leds on the sides of the crt monitor behind the bezel glass or in front of the sides of the glass? my cabinet is classic arcade cab with crt monitor 15khz hantarex polo slightly inclined, this inclination or
reflections of the glass they can create problems to precision of the gun?

thanks! :)

Well I placed them as you see in the pictures I posted, they are around 10 mm off the border of the screen.
As for the leds I do think these are perfect for the purpose, as it tracks them fine, but as I said, the scale is just wrong
No you can't, but if you have it licensed you can prove ownership. If you do see the code.

I do have an idea as to how to compensate for the offset.
if you initialize serial, which will respond to numbers which could be percentage of screen width.
With this offset you could just inset the mouse coordinates.

I do know its not easy to program something like this. And still think your work is awesome, even though I can't hit a damned thing ;D
