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 ...

We’ve covered plenty of persistence of vision (POV) displays before, but this one from [Vadim] is rather fun: it’s built on top of a PC fan. He’s participating in a robot building competition soon and ...

Noctua already makes some of the best PC fans out there, and now its arsenal is about to receive what seems to be a huge boost. As revealed during Computex, Noctua is working on a 140mm fan that’s ...

The Frore Systems AirJet Mini and AirJet Pro are active cooling chips that enable devices to become even thinner, quieter, cooler, and more powerful. The technology has the potential to replace ...

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 ...
