The purpose of this article is to explain how to make a CPU out of rocks and sand as fast as possible without using too many words. As the world of proprietary hardware and software crushes in around us, we risk losing the ability to make things for ourselves as individuals. It is for this reason that I felt compelled…
This article will discuss the setup steps that are required for recording videos at high frame rates on cheap Raspberry Pi cameras. Frame rates up to 660FPS on the V1 camera and up to 1007 on the V2 camera can be achieved. Filming at these extremely high frame rates on a Raspberry Pi is much more challenging and…

The ambient noise of police sirens can be heard in the background: "Ugh, the police are coming... So the instructions for the…
I recently came home to visit with family, but right now as I write this, it's 1:00am and I'm running memtest86+ by myself in the basement.

Indeed, this is probably the answer that I would have given just a couple years ago, but I have since become enlightened as to the…
