Digirule2

The Digirule2 is what you get when you cross a 1975 computer with a ruler. It is quite literally a computer on a ruler. Unlike what we are used to seen now, there was a time when binary was the only way to program a computer. Sometimes, as in the case of the Altair 8800, all you had to interact with and program a computer were nothing more than some switches and LEDs. Amazing to thing how far we have come.

This is something you could have some fun with if you re into this sort of thing, I must warn you though, it does not come with batteries, so you will hve to find your own.
