Amplifiers make heat when working. Too much of heat make it work bad and can die soon. This Temperature Controlled Fan Circuit for Audio Amplifiers keep amplifier cool. Fan starts only when amplifier is hot. If volume is low and less heat then fan stays OFF and saves power. The circuit is made with LM311 […]
Heater and Temperature Controllers
Adjustable Thermostat Circuit using IC LM56
Electronic adjustable thermostat control temperature and it is used in heating or cooling system. This Adjustable Thermostat Circuit using IC LM56 is a low power chip which switches temperature in two ways. It controls outside transistor for output load. IC LM56 give reliable, precise temperature control. It is good for many uses like check temperature […]
DIY Temperature-Controlled Fan Circuit with Arduino
Modern devices and homes need good temperature control. It help gadgets live long and make place comfortable. One example is fan with temperature control. Fan change speed by room temperature. This keep temperature okay, save power and with less noise. IC LM35 sensor is used for check the temperature. When it is too hot 5V […]
220V Temperature Controller Circuit
This post talks about 220V Temperature Controller Circuit in easy way. Circuit can turn ON or OFF heater, cooler or other things to keep same temperature. It uses big power like 220V. Has sensor like thermometer to check heat or cold. Has small brain chip or timer to decide when to turn ON or OFF […]
Simple Temperature Controlled DC Fan Circuit
Simple Temperature Controlled DC Fan Circuit is like smart fan. It use special sensor to feel heat around. When place get too hot then circuit makes fan run fast like turning AC high. If the place cools again then fan slow down or stop to save power. This circuit uses parts like thermistor which change […]
Induction Heater Circuit
This article for Induction Heater Circuit teaches us how to make one circuit. This circuit make iron things hot using magnet. We call this thing “induction heating.” WARNING: Making this circuit with big current and voltage is dangerous. Do only with adult watching and use good safety gear. Not good project for new people. What […]
