    Odd Inputs And Peculiar Peripherals: Using A Commodore Light Pen On A Modern(ish) Computer
    https://hackaday.com/2022/06/11/odd-inputs-and-peculiar-peripherals-using-a-commodore-light-pen-on-a-modernish-computer/

    We therefore applaud [Maciej Witkowiak]’s efforts to bring the light pen into the 21st century by building a USB interface for a Commodore 64/128 light pen. At its heart is an Arduino Micro Pro that implements the USB HID protocol to communicate with any modern computer. It connects to the classic light pen as well as to the computer’s analog display signal and uses those to calculate the delay between the video synchronization pulses and the light pen’s output. The sync pulses are extracted from the video signal by an LM1881, a sync separator chip that will be familiar to anyone who’s worked with analog video signals.

    Lightpen to USB HID interface
    Bring CRT displays and light pens into 21st century
    https://hackaday.io/project/179968-lightpen-to-usb-hid-interface

    The Arduino calculates the light pen’s position based on the measured timing intervals and reports it to the computer, using the absolute positioning mode that’s also used by things like drawing pads.

    Hence this project – everything this small Arduino Micro Pro does is to listen for signals from video decoder (LM1881) and record time offsets. Every VSYNC the results are reported through USB. Arduino describes itself as a mouse with absolute positioning reporting, like a drawing tablet.
