[Alan] put together a list of the Top 5 Dead Hard Drive Projects. He suggested we post about the hard drive laser oscilloscope, since he couldn’t find the project anywhere else. I actually saw a similar project during dorkbot-sf‘s presentation at Maker Faire. A laser is mounted to the drive case. The beam is bounced off of a mirror connected to the read/write head. He’s got a video of it in action on his site. Have a look at the other hard drive projects as well.
