[Gerry] built his own high stability timebase add-on for his HP 53131 frequency counter. This project started out after [Gerry] built a rubidium 10 MHz standard for his lab. Upon connecting the ...

Have you ever started a project, run into an issue, started a new project to solve the issue, and completely forgot about the original project? [Andy] went down a rabbit hole of needing a tool to ...

An Atmel AT90S2313 is being used on this frequency counter project along with 3 HC TTL chips and 3-digit 7-segment displays. An Atmel AT90S2313 is being used on this frequency counter project along ...

In this project we are building a basic and low cost frequency counter circuit . It can measure from 16Hz to 100Hz signals with a maximum amplitude of 15V. The sensitivity is high, the resolution is 0 ...
