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 As seen at downtown Los Angeles (DTLA) Mini Maker Faire 2018, it is an implementation of a 4-bit This run fills up the queues on the gates (AND,XOR) and collects the left over marbles when adding several 1bits. Here we just ... The video presents a device based on cams and strings that can compute the sum of three bits, providing a two bit result. Only running the clock. So that means 0+0=0. Making this using the earlier logic gates didnt
