Heather, Zach and myself created four logic gates out of Legos scrounged from various Lego Technics vehicle model kits. Full information and pictures after the jump…
Here’s an AND gate made using strings:
00 position
01 position
10 position
11 position, output is activated
MOVIE!
Here’s an Inverter created with rods:
0 postion, 1 output
1 postion, 0 output
MOVIE!
We made another Inverter with levers:
0 position, 1 output
1 postion, 0 output
MOVIE!
This is an NAND gate using the differential gearing from one of the vehicles:
MOVIE!
This is a NAND gate created by chaining our inverter to the string AND gate:
