A storm detector circuit is like a tiny weather genie in a bottle. It can sense the electrical crackle of lightning a telltale sign of a brewing storm nearby. This circuit uses an antenna to pick up these faint electromagnetic signals, kind of like a tiny radio. Since the signals are weak the circuit often […]
Sensors and Detectors
Simple Radiation Sensor Circuit
A radiation sensor circuit is like a tiny spy for invisible rays. It can sniff out different types of radiation, like the kind from light bulbs electromagnetic or even X rays ionizing. This circuit uses a special sensor that reacts to the radiation and sends a signal. The circuit then takes that signal and turns […]
Simple Static Electricity Detector Circuit
A static electricity detector is like an alarm for electricity that builds up on objects like your clothes. This can happen when you rub things together. This kind of electricity can damage delicate electronics, so this detector is helpful around them. The detector has a special sensor that can feel these electrical changes in the […]
Simple Heat Sensor Circuit using a Single Transistor
This simple heat sensor circuit uses just one transistor and a special resistor that acts like a thermometer. As things heat up, this resistor changes its behavior, which the transistor picks up on. Depending on the temperature, the transistor acts like a gatekeeper letting electricity flow through or blocking it completely. This way, the circuit […]
Simple Touch Controlled Potentiometer Circuit
This touch controlled potentiometer circuit lets you control things with just a tap. Forget fiddling with knobs or sliders simply touch a sensor to adjust resistance or voltage. It uses something called “capacitive sensing” which basically means your body acts like a switch when you touch the sensor. Pretty cool, right? Circuit Working: Parts List: […]
Simple Thunder Lightning Detector Circuit
This circuit shows you how to build a storm chasers tool a lightning detector! Lightning makes a special kind of electricity in the sky. This circuit can sense that electricity and light up or make a sound to warn you when a storm is nearby. This can give you extra time to get inside before […]
