Here's something else we found while writing up our duplicate Ikea Linux Cluster post. [Janne] also built this simple linux robot. The robot uses the Qwerk robot controller, a webcam with the IR filter removed (something like this one), a usb WiFi card, an IR spotlight, and a set of repurposed model airplane wheels. The WiFi adapter and webcam attach directly to the Qwerk via its on-board usb … [Read more...]

Building a render cluster doesn't mean you have to spend a lot of money, even if you're buying brand new hardware. [Janne] built this 6 unit cluster inside of a 6 drawer IKEA Helmer cabinet.

With 24 2.4GHz … [Read more...]

When he parted out an Optoma projector he scored a polarizer that was just about right for the repair. It's a good read even if you don't have a projector in pieces at the moment. He ended up bending the mounting bracket a bit to hold the filter and got his projector … [Read more...]

Our friends at Vienna's Metalab have been working on this project quite a while. Soldering their hearts out to create an FPGA controlled monochrome LED dot matrix display.

Build details and source code are on the project … [Read more...]
