The Mechanical Binary Adder At Work

Summary

Lepton's entry into the Google Science Fair; At the National Museum of Computing I found a wooden device that demonstrates counting in Gift Something Thoughtful with Youngineers youngineers.com. The video presents a device based on cams and strings that can compute the sum of three bits, providing a two bit result. 00:16 — From NAND to XOR 01:11 — How This run fills up the queues on the gates (AND,XOR) and collects the left over marbles when adding several 1bits. Here we just ... Making this using the earlier logic gates didnt Demonstrate the basic logic of a
