NerdKits Hard Drive Clock

I saw a video on YouTube a while back that showed the conversion of an old hard drive into a clock and I thought it would be an interesting NerdKit project.

Hi pej,

Great project and writeup! Lots of great design ideas both on the programming, electrical, and mechanical ends. And the final product is definitely really neat! I'm definitely going to have to think about building one of these.

Hi pej, thanks for sharing this interesting project.

On your project writeup page it appears that a link to a "video of the clock in operation" is not working. Also, would you please increase the size of the schematics diagram, I'm having trouble reading it.

Thanks for the feedback.

I checked the video and it looks ok to me so I'm not sure what is wrong (It's hosted on youtube, and directly available at ).

The schematic is now available as a pdf download ( which is bigger and easier to read.

The schematic I posted is added to the base nerdkits configuration. The normal program switch is still there, essentially in parallel with the optical sensor.
