Project Log 5: Portable cooling fan exploration
Project description
In this project, I share a simple cooling fan circuit that operates with a USB power bank or the USB of an ordinary laptop. The fan speed can also be adjusted to provide the level of air flow the user desires.

Here is the 1-minute video of the build process. You will also see the operation using a USB power bank as well as a laptop computer.
Why did I undertake this project?
I believe “simple is beautiful” and this applies to the electronic circuit projects I undertake regularly. Though simple is beautiful, “simple” still requires careful planning to be successful, and therefore there are challenges in such projects that keep me motivated. In this project, another thing that motivated me was the hot summer days and the need to have a simple cooling solution that did not take up too much space on my tiny study table already filled with lots of work-related items. Traditional desktop fans were not a viable option in my case.
