Eventorbot 3D Printer

Tired of 3D printers that use t-slot construction? The Eventorbot is yet another open source 3D printer,  but it’s built out of steel and 3D printable parts. The design also aims to minimize the effect of vibrations by using a single solid frame. All of the wiring runs through the steel frame, which gives the [...]

A watch for Curiosity’s drivers

After the twin rovers landed, the rover drivers would have to live on Mars time. Because a Martian day lasts 24 hours, 39 minutes, rover team [...]

Genetic Research on the Cheap

When you think of DIY hardware, genetic research tools are not something that typically comes to mind. But [Stacey] and [Matt]‘s OpenPCR project aims to enable anyone to do polymerase chain reaction (PCR) research on the cheap. PCR is a process that multiplies a specific piece of DNA a few million times. It can be used [...]
