# Non contact ac detector voltage tester using CD4060

Tools that features equivalent of a professional, easy to use, cheaper, and more importantly, safe for use. For checking to find AC 220 Volt or 120V or call that AC main power in various points have or not? Most use a screwdriver to check the electricity. It is a lightweight,… Read more »

# Simple Non-Contact AC Mains Voltage Detector

This is simple non-contact AC mains voltage detector next one circuit that use all transistor as main. Which many friends like this circuit. It use CD4060 as main,some people say that Can not find it. Today I would like to introduce another interesting cycle, because the transistor. It is certainly… Read more »

# AC wattmeter with power line frequency meter circuit

If you are looking for AC power measurement. To use it just a little, which is not worth it. When we need to buy an expensive tool. Because use little does not need high accuracy. I would like to propose the concept of wattmeter circuit in such a way easy… Read more »

# Simple AC wattmeter circuit

Schematic Diagrams      Comments Off on Simple AC wattmeter circuit

Power line frequency meter This is the meter show the frequency of a power generator, which it has voltage 110V-240V at 10-100HZ. The output sine waves are converted to square waves by the 100k 2 watt resistor and the 6.8V 1watt (1N3829A) zener diode. Then the square wave is transformed… Read more »
