Draw on LEDs using lasers

Technology

Here’s a cool project by Junichi Akita: it’s a modular LED display that you can draw on using a laser, then clear by tilting sideways. Unfortunately, the only documentation appears to be the paper, which is behind a paywall. Anyone up for a remake?

    Reminds me a little of Eiji Hayashi’s LED game Laser Command which also uses a laser to control. Plus he includes quite a bit of information on how to build it yourself.

    A quick google for “Matrix LED unit with pattern drawing and extensive connection” finds a 23MB pdf on this site: http://akita11.jp/plan/LT/
