Hard Drive LED Clock

Another cool alarm clock we came across was the no frills Hard Drive LED Clock. This DIY clock has been made from an old hard drive and uses a stroboscopic effect to display time as the drive spins!

“The hard drive platter has 10 digits cut all the way through it. Groups of LEDs in each character position can be strobed independently at any given time. By careful timing of the light strobes, an illusion of still-standing numbers can be created.” The only problem is that the clock is is pretty noisy while it spins and is not incredibly accurate. Nonetheless, it looks awesome!
