Battery Powered Frequency Meter (0 to 20kHz)
The circuit is a simple digital frequency meter that is made of a frequency-to-voltage converter and an analog-to-digital display converter that can be operatedfrom a single 9-volt battery. The TC7126 ADC generates the voltage required by the TC9400 FVC with internal regulators. The...

100MHZ Frequency Counter with PIC16F628A
This project shows how to build a very simple yet very useful tool that every DIY enthusiast should have in his lab: a 100MHz+ frequency counter. The schematic is fairly simple and straightforward and uses a PIC16F628A microcontroller for measuring frequency and a high speed...

Ovenized crystal oscillator frequency stability
E. Schrama @ ejo60.wordpress.com uses an Arduino and a DCF77 time signal receiver to test the stability of an ovenized crystal oscillator running at 1 MHz. In this experiment I will use an Arduino and a DCF77 time signal radio receiver to measure the stability of an ovenized crystal...
