Binary Calculator

oooh, love those blue LEDs

[Syst3mX] emailed us about his Binary Calculator earlier this week and it almost slipped into the depths of our inbox. Luckily We noticed it in there today and thought we’d share.

He wanted to be able to calculate binary values without having to jump through hoops or boot up his computer, so he built his own binary calculator. For the brains, he chose an ATTiny2313. He can do basic operations like NOT, AND, OR, XOR, addition, subtraction, multiplication, division and modulo. It isn’t too bad looking either. You can catch a video of it in action after the break.

Shovel…guitar?

We didn’t believe this hack at all when we saw it, or rather heard it. Surly a guitar made out of a shovel couldn’t sound decent. But the video (after the jump, skip to 2:40 for the jam) to our untrained ears sounded pretty rad. Could be the supremely well done wood work, proper use of tools, high tech pickups, or maybe Russian magic, we don’t know.

In fact, if you continue the video it doesn’t stop there. The creators also made a 2 string bass and a few other instruments from shovels. Do I smell a new shovel hero?
