Kale_3D has posted this instructable about his build of an Arduino-based calculator with a laser cut wooden enclosure.

In this Instructable I will show you how to make an Arduino calculator that is just as good as any other calculator (well… sort of). Even though it’s probably not practical due to it’s size, repetitive use of the equals button (due to the lack of keys), and cost (You can probably buy a calculator that does the same thing for $2), It is really fun and adds a few skills to your inventory. Let me tell you how I got started on this project. It all starts at school where the original calculator was made by my friend/teacher Gabe. If your curious how the old version looked click here. Soon enough students began to play with it and soon broke it. I was the only student who knew how to fix it so I decided I might as well try. In the process I basically took the whole thing apart and started from scratch. I also rewrote most of the code. I learned alot, spent lots of time debugging, and added many new features. In the end it was a project definitely worth doing. The good thing is that now that I figured it out you don’t have to. Let’s get started.
