Scott Wiedemann | LEGO Logic Gates - Half Adder @lemmingapex | Uploaded 10 years ago | Updated 3 hours ago
A half adder I built from LEGOs. The half adder is built form only OR and NOT gates. The amount of mechanical imprecision and friction in the half adder suggests that a full adder with a similar design would have issues functioning.
If you are interested in building one, here's where I ordered the parts from: http://www.bricklink.com/store.asp?p=ToyBrickBrigade
