A MOC modular binary counter is presented and used to measure the RPM of a large Technic motor. The counter is constructed of a series of 4 sides reels each representing 2 bits. These are held at neat 90 degree angle multiples by a micro stepper mechanism. The overflow bits are carried to the next reel using a 4 knob wheel pushed by a small lever arm from the previous reel. The design is modular such that multiple modules can be combined to create a larger counter. The counter demonstrated is made from 3 modules and can count from 0 to 4095 in binary. Enjoy! -
This Pi Day model demonstrates how to approximate a gearing ratio of Pi by representing Pi as a binary number and using differentials arranged in a chain formation to create the binary representation. Each differential implements 1 binary digit. If the binary digit is zero the differential can be replaced by a gearing ratio of a half to reduce the number of differentials required. This model has 23 binary digits and approximates Pi to 7 significant figures, uses 202 gears and is driven by a median PF motor.

Hi Everyone, Here are the instructions on Rebrickable for the modular binary counter MOC I made a while ago. https://rebrickable.com/mocs/MOC-43585/TechnicBrickPower/modular-binary-counter/ Thanks to 1963Maniac for creating the instructions - great work as always and much appreciated. This is the youtube video showing how the model works:
