Weather Station

2022-12-22

Raspberry Pi Zero W As the holidays fell, I forgot that I failed to put a weather station on my list. I had been wanting one for quite some time now, mostly just to check the pressure for fishing. Well, I realized that I could just build a mini on-line weather station using an old Raspberry Pi Zero W I had taking up space in my drawer. So I set forth to build it.…

Network Analysis

2022-10-24

This plot is a network of co-authors for MIS-C published studies from PubMed. MIS-C is an inflammatory disease related to Kawasaki’s disease that affects children who have been infected with COVID-19. I have plotted this to demonstrate how publically available data can be used to perform a network analysis. To get started, search for MIS-C over at PubMed. Download the full dataset as a CSV file. This will be formatted in a typically citation style export.…

TRS-80_Model_100 I recently acquired one of the worlds first truly portable computers that is laptop sized, the Tandy TRS-80 Model 100. This computer was released around 1983. It contains a full keyboard, runs MS BASIC, and can be powered off 4 AA batteries for roughly 20 hours. At its core is a 2.4 MHz 8085 microprocessor with 24K RAM. That’s about 55X the compute power and 1/3 the memory that the Apollo program used to send men to the moon!…

Automata

2022-08-24

For awhile now I have had more than a passing interest in a computer science phenomenon known as cellular automata. These are computations that follow a set of rules (aka algorithms) to produce “cells” of that morph overtime and can make elaborate and often complex structures from relatively simple rules. While these were discovered in the 1940’s, the classic example of cellular automata is Conway’s Game of Life (https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life) .…
