This projects is a mix of two of my main passions, Arduino and Wind. Here is a simple project that I used this OLD PC fan as a small wind generator to sense the wind speed. Here we are using modified PC fan as a wind speed sensor using Arduino and showing the results on a smartphone running the […]

The popular UGOOS brand has announced the launch of a TV Box powered by Amlogic S922X SoC called UGOOS AM6. Ugoos AM6, in contrast with older model, will include a fan for active cooling, providing optimal performance for the new Amlogic processor. While there are no available photos of the enclosure so far, Ugoos share some pictures of the board and

As summer is coming, I bought a USB fan from HuaQiangBei, Shenzhen. However, when I focus myself on work(or game), I could hardly notice its existence. If I can teach it how to think and execute its duty without my order, that will be more practical and fun! So roll your sleeves and follow me

I published this schematic long ago in this article: Adjustable power supply and since then I made some improvements in PCB to make the board as small as possible. The idea is to be easy to attach the whole board to the heat sink which we want to monitor. The board is only 27mm x

Still more noise and vibrations and in extreme case even a total malfunction – this is a typical “end” of the fan after a long-time operation in a dusty or corrosive environment. In a usual dry and relatively clean environment, this scenario is not that dramatic and high-quality fans hold on to work for many
Have you ever seen a fan resistant to dust and water Continue Reading
Here we are going to make a temperature controlled DC fan. DHT22 sensor is used to sense the room temperature and then we adjust speed of a DC fan/motor accordingly using PWM (Pulse Width Modulation). Arduino Uno is the heart of this project and a L293D driver IC is used to drive the DC fan/motor. Components Required

A hideaway cat litter box is a great way to make your apartment look like a residence for adults instead of crazy cat ladies. A hidden litter box in a cabinet, under a sink, or built in to some other furniture does a lot for appearances, but what about the smell? Here’s how you can

Most desk fans I have come across have three speeds: Full Speed, Almost Full Speed, and Off – useless if you want just a gentle air movement, and far too noisy if you are trying to get to sleep (in your bedroom of course, not at your work desk!). The squirrel cage induction motors they

I saw these POV(Persistence of Vision) devices on other Instructables and thought I would like to make one and I have always wanted my own “APPLAUSE” sign. Next improvement will be to make it go on whenever I enter the room. 🙂 Maybe have it say, “And here’s Charlie !” But that is for another
Arduino + LEDs + fan = POV “APPLAUSE” sign Continue Reading
Oscar Gonzalez gives us a simple tutorial for speed controlling a PC FAN and reading a LM35 temperature sensor with an Arduino microcontroller. He covers the use of an optocoupler, PWM (Pulse Width Modulation) and reading analog voltages with the Arduino. He even has a video showing the fan speed control in action. This article
