In this article we discuss a simple temperature controlled relay circuit which can be switched ON/OFF depending on the temperature on its temperature sensor. Meaning, when the temperature on its […]
Simple Temperature Indicator using Thermistors
A thermometer may be required for the precise measurement of temperatures. However, in many cases, an absolute value isn’t required and a relative estimate is sufficient. For example, the consumer […]
How to Calculate Heatsinks
Heatsinking is critical for power devices in circuits that are intended to maximize their performance. When heat from the power devices cannot be moved away very quickly, the power devices and its […]
Tap Water Induction Heater Circuit
A tap water heater circuit can be simply built by attaching an iron tube on the mouth of the tap or the faucet, and allow the iron pipe to pass […]
100 °C to 1000 °C Thermocouple Temperature Meter Circuit
The post explains a simple op amp based thermocouple temperature meter circuit which can be used for measuring high temperatures in the range of 100 °C to 1000 °C, in […]
Using Microwave Oven Parts to build a Soldering Iron Heat Controller
In this post we learn how to scavenge discarded microwave oven parts for making a useful soldering iron heat controller circuit which can then be used for maintaining controlled heat […]
