Stroboscope LED fan clock - Hack a Day

Stroboscope LED fan clock

[sprite_tm] sent in one of his latest little adventures – and I love it. To create his stroboscope fan clock, he put a couple of red and green clock hands onto a standard PC fan(I love Panaflo fans), then he built a circuit to strobe a RGB LED to create a set of virtual clock hands on the spinning fan. An ATTiny2313 does all the work, with the help of some transistors to drive the LEDs.

tangential, but I wonder if it’s possible to create a strobe tuner with a PC fan and an led/laser?
