LED Clock – Part 2

In part 1 of this series I demonstrated how I created a clock using my 64x32 LED panel. In this blog I will expand upon this experiment and add current weather observations as a scrolling ticker across the bottom of the panel. The first step to add weather observations to the clock is to register … Continue reading LED Clock – Part 2 →

LED Clock – Part 1

Over the Christmas break I had some fun with my MLB LED scoreboard (see that blog for a BOM and specifications). The LED panel doesn't get much use during the offseason, so I decided to learn how to program it as a clock when it wasn't functioning as a scoreboard. The next few blogs will … Continue reading LED Clock – Part 1 →

Blackjack (a.k.a 21) Simulation

Finding none, I decided to use this opportunity to teach myself Python and parse the the MLB dataset to find it myself. MLB publishes a dizzying amount of data (XML) every 20 seconds or … Continue reading My Live MLB Scoreboard →

Levenshtein Distance

A few years ago, while I was doing research for my Similarity Index paper and prototype, I ran across the idea of the Levenshtein Distance. Basically the Levenshtein Distance (LD) is a metric to determine the minimum cost of edits (i.e., insert, delete, or substitute) required to transform one word (or sequence of characters) into … Continue reading Levenshtein Distance →

MLB LED Scoreboard for Opening Day 2019

The GitHub project contains nearly all the information you need: https://github.com/MLB-LED-Scoreboard/mlb-led-scoreboard.  The accompanying WiKi has good info also, including the parts list and … Continue reading MLB LED Scoreboard for Opening Day 2019 →
