murderbot supercomputer from 2001: A Space Odyssey, HAL 9000, holds a special place in the hearts of many sci-fi fans. HAL's distinctive red eye and calm voice has often been replicated, be it in other movies or even expensive props you can buy. However, if you're more of a do-it-yourselfer and want to save some cash, you can build your own HAL 9000 for less than $100. It does require a fair bit of technical and soldering know-how, not to mention a laser cutter and plenty of patience, but this craft project is well worth it. Adding sound to your own HAL 9000 requires an Arduino Uno and Adafruit Wave Shield, but both can be had for around $50 and really, what good is a murderous computer without that calm voice telling you something can't be done?
Head on over to the source to see everything involved with getting your own HAL 9000 up and running. Remember, if it starts singing "Daisy Bell," find a spacesuit.
