Yes, those are my veins. This series of images was generated by the Christie DLP VeinViewer [PDF]. This device projects infrared light onto your hand. A camera detects areas with blood vessels near the skin because blood doesn’t reflect the IR light, but the surrounding tissue does. The resulting image is projected onto my hand by […]

They built it for CWI’s exposition “Turings Erfenis” in honor of the centenary of Alan Turing’s birth on 23 June 1912. Alan Turing was a brilliant mathematician who […]
Seems like there are a number of low power ARM SoC boards hitting the market recently.

It’s an Allwinner A10 ARM SoC with 512MB RAM, 4GB onboard flash (up to 16GB with MicroSD), b/g/n Wifi, and goes for £40
