SPINmaster, a DIY staggered hard disk spin-up manager

Spotted in the MAKE Flickr pool:

Bryan Levin was apparently having problems with cheap computer power supplies that couldn’t handle turning all of his drives on at the same time. Rather than just buy a beefier power supply, he decided to build this SPINmaster device to turn them on one at a time. He’s got a few more photos of the project on his Flickr page. Looks great!
