God I hope you're right that your flash doesn't let UV pass.
The very nature of a photoflash is a high-intensity broad-spectrum emission of visible and invisible light - flash tubes themselves have a coating on them which severely reduces the amount of UV light allowed to pass through. At any rate, your average flashgun will probably have something to inhibit the transmission of UV light, but I still wouldn't trust it myself.
I'm probably just overly cautious.
BTW - has anyone looked at the Keyboard Babel project for ADB -> PS/2 conversion to implement in a microcontroller of some description?
The mouse could be done with some discrete logic easily enough - just look what an ADB mouse does on-circuit to the pulses from the rotary encoders. I think it uses a quadrature latch of some kind? If you can essentially strip the serial mouse or PS/2 mouse to the basic data of "motion x/y, direction x/y" and the button press activity, and then use that to drive whatever turns a dumb mouse into an ADB device, you have the mouse side dealt with easily.
If one wanted to be all fancy and neat and tidy, implementing a softcore 6811 in a CPLD, and using the remaining space to chain the logic for the mouse, would be an elegant solution. (I hate hate hate hate miniaturisation and over-integration, I'd rather replace a 74xx or a few transistors than an ASIC, but what do I know)
