Temperature Controllers

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 operating elements could be damaged. You may calculate how hot your semiconductors could become while operating, using a couple of easy formulas. Using formulas gets rid of guesswork and […]

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 through an induction heater coil. The induction heater will heat up the iron pipe and hence water passing through the the pipe will also heat […]

In this post I have explained 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 heaters, furnaces, kilns tec. What is a Thermocouple A thermocouple is a simplest and the cheapest form of temperature sensor device, built […]

In this post I have explained 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 over a connected soldering iron tip ensuring safe soldering operations, that may be quite crucial and handy if you are working with SMD parts. […]

In this post I have explained how to make small homemade induction heater circuit for laboratories and shops for carrying out small scale heating jobs such as melting ornaments, or boiling small quantity of liquids using electricity or battery The idea was requested by Mr. Suni and Mr. naeem Circuit Objectives and Requirements Our challenge […]

In this post I have explained a simple food warmer lamp timer circuit for restaurants and hotels which can be used for automatically switching OFF the lamps after a predetermined time whenever the food under the lamps are idle or in the absence of an interaction under the lamps, thus saving precious electricity. The idea […]
