Old Fasion DIY Calculator

Aaron from Arron Adding Machines.Com makes and sells "antique calculators" He hand makes each of them using old wood that he finds from various places and gives them a nice antique stain. Then he drills holes in it and adds buttons from Radio Shack which hook up to a circuit board that goes to a red led display. Although this wouldn't be too hard to make it's still a great idea so good job Aaron!
