The great thing about building with gates is the crazy speeds you can achieve by using hardware directly (as opposed to working with simple microcontrollers). This 100 MHz frequency counter is a great ...

The project was created to turn a multimeter into a sensitive frequency counter with a wide counting range. An old frequency counter can be upgraded using this project and the range can be extended up ...

The project utilizes an AVR controller that can be used as a counter by being more involved with a PIC which has synchronous counter input. The PIC input can handle frequencies up to 40MHz.

The Model 1856C frequency counter is capable of measuring from 5 Hz to 2.4 GHz and features a special 50½-terminated input for use in with VHF, UHF, microwave, and cellular telephone systems. A ...

Get to really know the fundamentals behind your test equipment. Not only do you reap the most out of your scopes, etc. as well as avoid debugging traps—it can also facilitate a “spec hack.” Everyone ...

Sometimes when you build something it is because you have set out with a clear idea or specification in mind, but it’s not always that way. Take [kodera2t]’s project, he set out to master the ATtiny ...
