Max. Range: 9,950 meters with two digits slip it in pants’ pocket For walking and jogging This circuit measures the distance covered during a walk. Hardware is located in a small box slipped in pants’ ...

Designed a 4-bit counter using a J-K flip-flop that has a clocked input with reset. Performed simulations of various output parameters like rise time and fall time. The design is done using cadence ...

This is an oldie, but oh, man is this ever good. It’s a Nixie clock made without a microcontroller. In fact, there aren’t any logic chips in this circuit, either. As far as we can tell, the logic in ...
