Strobeshnik (final),Tech,hdd,clock,strobe,platter,avr,Strobeshnik is a HDD clock. The digits are etched in the original platter and they're strobed from behind with leds. The HDD motor is driven by a custom circuit without feedback, hence poor startup performance and awful noise. Rotational feedback is provided by an IR LED/phototransistor pair near the place where the head arm formerly was. http://sensi.org/~svo/strobeshnik for more info
