Make Cool Stuff: Digi-Comp II

Nerds! I’m so excited I can barely contain myself!

Why? I’ve been catching up on the various feeds in my reader and finally got to reading a couple weeks worth of Evil Mad Scientist Laboratories posts. The first thing you need to know about these cats (note: not real cats) is that they’re awesome. The second thing to know is roughly 40% of their posts go right over my head – but the ones that don’t are pretty wicked cool.

They just got back from the 2011 Bay Area Maker Faire where they debuted this baby:

To me, this is the definition of nerdy: it’s a large-scale reproduction of a childhood educational toy. IT DOES NOT GET BETTER THAN THIS, PEOPLE!

Okay, I’ll calm down. I’m sorry I yelled.

Normally I wouldn’t link you to something you couldn’t build yourself, but I think it’s safe to assume most of us don’t have loading docks or tons of free space available to build a giant Digi-Comp II. Don’t despair, this does bring to mind a few cool projects:

  1. That is epic geekery at it’s finest. Anyone else happy that they solved that minus about 5minutes and 11seconds – hours sawing, drilling, and gluing – trip to the hardware store – several trips to different sporting goods stores looking for that many 8 balls… that 3×13= SPOILER ALERT! …39!? Maybe it’s just me. 😉

    If they could invent a lavaliere microphone I’d be able to hear them over the parade of 8-balls.

  4. I love EMS Laboratories!

    You also may know them from their “Candy Fab” sugar-based 3D printer and the “Kindling” portable wooden reading device. They are the people who are making the things that no one else is making.
