It may be 2013, but 2001 will forever hold a special place in our hearts, in no small part due to the that lovable, red-eyed supercomputer known as HAL 9000. ThinkGeek has given us a couple ways to purchase HAL for our homes, but for folks who'd rather build their own, Adafruit's got you covered. User Phillip Burgess has posted the full instructions on how to craft one, provided you've got access to a laser cutter and the requisite soldering, spray painting and sanding chops to complete the task. Adafruit's version will have you making HAL out of an oversized arcade button and a sheet of acrylic -- and if you want your HAL to talk (and really, why wouldn't you), you'll need to build a voice box from an Arduino Uno board and an Adafruit Wave Shield. Total cost: just shy of $100. Check out the video of it in action after the break, and head on down to the source link for the full how-to. Oh, and feel free to whistle Sprach Zarathustra while you work.
