I needed to test some crystals for a project I was working on. I found lots of testers on the internet, but they all where lacking in one th...

The idea for this crystal tester circuit sprung out of the need of testing a large number of oscillator crystals lying unused in a big hobby...

You cannot use a multimeter to check a crystal. You should have a this circuit, because it can check a crystal 100Khz to 900Mhz, easily to m...

A very useful project of a crystal tester circuit or xtal tester circuit built with only few components the circuit form an oscillator that ...

A crystal tester circuit is very simple, it contains only oscillator and detector inside. This crystal tester circuit uses one transistor fo...

Ql acts as a Colpitis crystal oscillator, and if the crystal under test is operational, the RF signal is rectified by D1 and D2, turning on...

This circuit will check a crystal for activity. Two sections of a 7400 act as an oscillator and its output is rectified and drives an npn t...

Transistor Ql, a 2N3563, and its associated components form an oscillator circuit that will oscillate if, and only if, a good crystal is con...

This is a simple XTal tester circuit. T1 and XTal have formed an oscillator. C1 and C2 are voltage divider for oscillator. if the XTal is sa...
