It might not do much for your Folding@home score, but you can seriously up your geek cred with this 2.0 update to the classic DIGI-COMP I of the 60's. Originals go for upwards of $100 on E-Bay, but this new and improved version of the build-your-own-mechanical-computer goes for $50 and still crunches that Boolean logic like it's 1968.
