Simple Storm Detector Circuit is like small weather magic in box. It can feel lightnings electric noise which shows storm is coming near. This circuit uses one antenna to catch small signal in air like small radio. But signal being weak it uses amplifier to make signal strong. Sometimes it also uses special filter to […]
Sensors and Detectors
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. 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 showing […]
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 […]
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 […]
Touch Controlled Potentiometer Circuit
This Touch Controlled Potentiometer Circuit one just need to tap it and it will start to work. No need to turn knob or move the slider it just touches the sensor and it changes the resistance or voltage. It uses capacitive sensing which means that when one contacts it, the body will act as a […]
Thunder Lightning Detector Circuit
This Thunder Lightning Detector Circuit teaches us how to make lightning detector, a tool used by storm chasers! Lightning makes special energy in sky. When storm come this circuit find that energy and give alert by light or sound. So person can go safe place before rain start. Circuit Working: Parts List: Category Item Quantity […]
