Making a GOOGOL:1 Reduction with Lego Gears

Building a long gear train using 186 Lego gears. Many different types of Lego gears are used. Enjoy!

Inspired by Daniel de Bruin's "universe's biggest gear reduction":


The finished gear ratio:
10341796308487334800992832804222885104773611498499997696000000000000000000000000000000000000000000000:1
or 1.0342e100:1
or 1.034 GOOGOL:1

Rotation time for the last gear:
52433879932503535381614991275498187972589101825233846406570841889117043121149897330595482546 years
or 5.2434e91 years

Formula for the gear ratio:
24/8 * 40/8 * 40/8 * 40/8 * 60/1 * 12/1 * 168/1 * (140 / 8 + 1) * 141 * 20/12 * (40/8)^20 * 20/12 * (24/1)^20 * 56/16 * (36/1)^10 * (40/1)^18 * 15/9 * 56/1
