This DIY LED Binary calculator may seem a little geeky, but if you’re tired of the same old boring calculators that have absolutely no life or character to them, then this tool designed by Instructables should get you pretty excited.

Even if you’re not a lover of math -- such as myself -- maybe the bright blue LED lights will make you take a second look at this nifty little device. More than just a binary calculator, this DIY LED Binary calculator does all the basic functions as well, such as addition, subtraction, multiplication and division. Thumbs up for innovative thought and double thumbs up for making a calculator super-cool.
