I have a long and hard battle with mosquitos. Living in Singapore, I have two choices: open my windows and get bitten by those horrible itch inducing flyimg creatures, or close my windows and steam myself to death. To rub salt into my wounds, the glorious magnanimous town council decided too paint my level brown, you know, to make the stripe on a white apartment block. I guess not everyone, especially in political scene, knows basic physics.
I have tried many methods, from planting mints and rosemaries outside my windows, to vaporising some anti mosquitos, to install fiber screen. The fiber screen helps keeping out the mosquitoes, at the price of not lettinguch air in or out of my room. So, after a few months of internal debates about whether I should do it, I finally made my room ventilator.

Not a fancy contraption, I believe. A simple 2 computer fans ( low noise, high airflow), connected to a PWM motor controller. Power is supplied by an old power supplies I found around my house, rated 15V 1.2A. the whole thing is fitted to the smaller window, so no mosquitoes should be able to fly through.
PWM controller can be found easily on aliexpress:

I salvaged the power supply from my trash, so no link. It is also easy to find something similar on aliexpress for cheap:

As each fan is rated 12V 0.22A, 1A power supply would be more than adequate.
It works perfectly together with the screen by creating positive pressure inside my room. Fresh air from the vent, hot air through screen. And I finally can get my good night rest mosquitoes free.
