The Raspberry Pi is still picking up momentum with different types of DIY projects. If you're looking for a means to build an old-school computer-in-a-keyboard with a Raspberry Pi, the German blog Preamp shows you exactly how to do it.
The build uses a Cherry G80-3000 keyboard, and then proceeds to stuff the Raspberry Pi into the back of it. Next up comes a few mods to the case for USB output, an HDMI port, and more. The end result is, just as you'd expect, a computer stuffed into a keyboard that's easily transportable to any monitor in the house. Head over to Preamp for all the instructions.
