Most of us using desktop computers, and plenty of us on laptops, have some sort of fan or pump installed in our computer to remove heat and keep our machines running at the most optimum temperature.

From the lazy-but-totally-awesome files: Here are two solutions for making your fan automatically turn on once the air reaches a certain temperature, so you don’t have to move a muscle. Instructables ...

We all love the sound of a new exhaust system, the thump of a hot camshaft, and the thrust of added torque, but all too often we ignore those sub systems that our hot rods depend on to get from point ...

If you love fooling around with electronics, building devices, and generally just tinkering with circuits and boards to find out what they can do, then you undoubtedly know — and likely love — Arduino ...

Now that summer is coming, it’s time to break out the Air Conditioners! There are some old AC units out there that still work just fine, but nowadays we are used to everything being remotely ...

Orion Fans has developed a new, low-cost AC three-position short fan tray with an energy-efficient smart thermal control. Orion Fans has developed a new, low-cost AC three-position short fan tray with ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...
