Sorry for disappearing for so long - work and school have been a nightmare. I've received all my necessary parts, soldered a working switch connection, but there's still one thing in my way - the mounting solution for the aimtrak board. I purchased two SEGA IR caps/holders, and have absolutely savaged one with a hacksaw and file trying to create a space for the board to slide into - ultimately, I couldn't get the board in far enough and the crosshair was only really useful in the middle of the screen.
Does anyone have any ideas for a simple DIY solution including the authentic IR caps?
