Fresh hacks every day
There are awesome projects, and then there are things that make us drool on the keyboard. We just got done wiping up our mess after seeing this go-kart which uses four hub-motors as direct drive wheels. We'll admit, this is more artwork than a hack as these guys are mechanical engineers and know what they're doing. But how could we pass up sharing something like this? The design is smaller than … [Read more...]
There is a long tradition of hacking transportation to work on the rails. People have done it to all kinds of things for many reasons. Some are for rail maintenance, others are simply to enjoy the tracks. With as much unused railways as we have, it seems a shame to waste them. This hack turns a bicycle into into a rail bike with the use of some conduit, a cut up razor scooter, and a fork from … [Read more...]

Initially, he attempted to use microwave motors but ultimately found them to be too weak to force the bits of cat food should they get stuck. He was … [Read more...]
Summer is right around the corner and all the final projects from electronic design classes are rolling into the tip line.

The keyboard has two modes: a 'happy' mode and a 'tender' mode, the difference being the tender mode is slower and sounds a little like a lullaby. After two keys … [Read more...]
Although not a hack in the sense that it was made by a large corporation, check out this capacitive electronic disk that [danielbpm] wrote in about. Here's a Wikipedia article about it, as well as a video (which didn't embed correctly) about how it was made. The disks look like a typical audio record, and it was conceived of in 1964. A prototype was manufactured in 1972. Unlike the more … [Read more...]
