Simple Micro Ampere Meter Circuit is like a special tool to measure small electric, normal tools too are strong but are not good for tiny current. But this one uses super sensitive meter microammeter or maybe special setting on multimeter to find very small electric flow like millionth of amp. Also, other parts like resistors […]
Meters and Testers
Simple Electronic Component Tester Circuit
This Simple Electronic Component Tester Circuit works like doctor for ones electronic parts. Before we make any cool thing one can use this tester to check parts like resistor, capacitor, transistor and many more. Furthermore, tester shows if the parts are good or bad, so we do not waste time with broken parts in our […]
Simple Contactless 220V Phase Detector Circuit using IC 4017
In this post we will see how to make Simple Contactless 220V Phase Detector Circuit using IC 4017, as this small tool help to check wire or cable if current is inside or not without touching it. Also, this circuit is very useful for electrician to find problem in big electric system; if current is […]
Wireless RF Network Cable Tester Circuit
Wireless RF Network Cable Tester Circuit is like X-ray for internet wire, which can catch radio signal inside cable like ethernet, modem or satellite TV but there is no need to touch the wire. Also, it is very easy to use for checking cable working or not; for that just hold tester near the wire […]
Simple Temperature Meter Circuit
Simple Temperature Meter Circuit is like small detective for heat, as it use special sensor like thermocouple or thermistor to feel heat near it. Here, the sensor can be small part or smart chip like LM35 or LM34 which change heat into electric signal; then circuit take this signal and confirms how much hot or […]
Simple Fatigue Testing Circuit
This small and simple Fatigue Testing Circuit is a fun way to check whether someone feels tired or not! it makes LED blink very fast and we can change how fast it blink. Also, if we are not tired, we can still see the LED blink even when it flashes fast; however, if we are […]
