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 […]
Sensors and Detectors
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 Radiation Sensor Circuit
Simple Radiation Sensor Circuit is like small spy for rays which one cannot see, it can smell different radiation like from light bulb, electromagnetic, or X-ray (ionizing one) etc. Furthermore, this circuit have special sensor when radiation detects sensor feels it and send signal. The circuit then uses that signal to modify things such as […]
Simple Temperature Controlled DC Fan Circuit
Simple Temperature Controlled DC Fan Circuit is like smart fan, which uses special sensor to feel heat around; so when place, it get too hot then circuit makes fan run fast like turning AC high. Therefore, if the place cools again then fan slow down or stop to save power, hence, this circuit uses parts […]
Simple Static Electricity Detector Circuit
Simple Static Electricity Detector Circuit is like alarm for electricity when gathers on things like clothes and this happen when we rub things together. Also, this kind of electricity can break small electronics, so detector is useful near them; also detector have special sensor which feels electric change in air. Maybe its wire stick out […]
Thermometer Circuit
Thermometer Circuit is like a small detective for heat, as it has got special sensor which smells temperature and then show on the screen like digital thermometer. Also, these circuits come in many shape and size for the use in different way to feel temperature, but no matter which one all of them will indicate […]
