[Scott] built this frequency counter using less than $10 in parts. It’s set up to meter frequencies in megahertz which is fitting since he’s planning to use it with his radio hardware experimentation.

Everyone loves a bargain. Who doesn’t love a hacked oscilloscope? Well, it would be unusual for an oscilloscope company to teach you how to hack your own hardware. Besides, that’s already been done ...

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.

In my previous design idea, a design for a simple GPS disciplined oscillator (GPSDO) 10 MHz reference was presented. A note at the end of that article describes the realization that a frequency ...

Hackaday Editors Elliot Williams and Mike Szczys work their way through a fantastic week of hacks. From a rideable tank tread to spoofing radio time servers and from tune-playing vacuum cleaners to an ...

In frequency counters, the gating time allotted for counting is often too short to resolve low frequencies. A phase-locked loop could be used to multiply the input frequency. But in some cases, the ...
