Attention lapses due to sleep deprivation due to flushing fluid from brain
An MIT study reveals what happens in the brain as lapses of attention occur following sleep deprivation. During these lapses, a wave of cerebrospinal fluid flows out of the brain — a process that typically occurs during sleep and helps to wash away waste products that have built up during the day.

Why I Keep a Research Blog
Before I started taking writing seriously, I had a loose grasp of many mathematical and technical concepts; and I was not sure how to tackle open-ended problems. Maintaining this research blog has clarified my thoughts and improved how I approach research problems. The goal of this post is to explain why I have found…

How to make a CPU – a simple picture-based explanation
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…

A new replication crisis: Research that is less likely to be true is cited more
Papers in leading psychology, economic and science journals that fail to replicate and therefore are less likely to be true are often the most cited papers in academic research, according to a new study by the University of California San Diego’s Rady School of Management.

Why does a spray bottle work?
Exploring a simple machine I took apart a simple spray bottle to see how it kept fluid flowing only in one direction from the reservoir to the nozzle. It does so with simple check valves made of two pieces of plastic, a spring, and a small sphere. It’s a simple way to solve a tricky problem. A simple spray bottle One…

Phased Array Microphone (2023)
A 192-channel phased array microphone, with FPGA data acquisition and beamforming/visualization on the GPU. Phased arrays allow for applications not possible with traditional directional microphones, as the directionality can be changed instantly, after the recording is made, or even be focused at hundreds of…

AWS Ground Station – Ingest and Process Data from Orbiting Satellites
Did you know that there are currently thousands of satellites orbiting the Earth? I certainly did not, and would have guessed a few hundred at most. Today, high school and college students design, fabricate, and launch nano-, pico-, and even femto-satellites such as CubeSats, PocketQubes, and SunCubes. On the…
