Think heatsink like small radiator for our devices which help keep cool. Heatsink Temperature Protection Circuit is like safety man for that small radiator. It got small sensor by always checking heatsink heat. If too hot like one have got fever then this circuit does something. It maybe a stop power or maybe like start […]
Simple Static Electricity Detector Circuit
Simple Static Electricity Detector Circuit is like alarm for electricity when gathers on things like clothes. This happen when we rub things together. This kind of electricity can break small electronics so detector is useful near them. Detector have special sensor which feels electric change in air. Maybe its wire stick out or maybe flat […]
DC Voltage Doubler Circuit
DC Voltage Doubler Circuit is like small power booster. It takes normal battery power and make almost double. It use smart parts like diodes and capacitors and they work like tiny switch and small electric bucket. Sometimes many also use transistor or tiny chip to help. Imagine electric flow from battery like small stream. This […]
Thermometer Circuit
Thermometer Circuit is like a small detective for heat. It has got special sensor which smells temperature and then show on the screen like digital thermometer. 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 which one […]
Simple TV Remote Tester Circuit
Simple TV Remote Tester Circuit is small tool like A doctor for ones remote. It uses one infrared sensor like eye for light which we cannot see and to check if remote give signal when one presses the button. If signal arrives small light turns ON or buzzer make beep sound which means remote is […]
Simple Heat Sensor Circuit using a Single Transistor
This Simple Heat Sensor Circuit using a Single Transistor and one special resistor like thermometer. When it get hot this resistor changes to how it work because of which the transistor sees this change. Transistor work like door and if temperature changes it opens or closes for electric. So the circuit can detect when something […]
