[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.
