Frustrated with a curriculum change away from traditional CS courses in public schools, game developer David Braben built an ultra-low cost single board computer on a USB stick to facilitate a return to programming and learning how computers actually work. Connecting directly to a keyboard, with HDMI out to a monitor, the idea is to build courses around the tiny $25 PC, which is cheap enough to get into the hands of most students. And just because it’s inexpensive doesn’t mean it’s a dog. Sporting a 700MHz ARM 11 with 128MB of RAM and OpenGL ES 2.0 graphics means it has enough power to run Ubuntu. [via YC]
