Posted May 12, 20204 yr 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!

Yes it's a neat build and the fact that's it's made from lego would make it more interesting for kids & adults! Are you interested in the build instructions?
