My cardboard prototype of the central portion of a Class 80x dashboard allowed me to iterate to a laser-cut hardboard prototype.| Christopher Mitchell, Ph.D.
After sourcing rough measurements of the dashboard of a Class 80x train, I began creating a cardboard prototype, plus associated CAD designs to get the design fabricated.| Christopher Mitchell, Ph.D.
Graph3CE is a 3D graphing application for the TI-84 Plus CE. Inspired by my previous 3D graphing tools for graphing calculators, and adapted from my Casio Prizm tool Graph3DP, this project lets TI-84 Plus CE users graph up to six equations in 3D, examine their values via trace, and rotate and zoom them. Here’s how I created it.| Project Blog on Christopher Mitchell, Ph.D.
My several iterations over a CAN bus controller for my Train Simulator physical dashboard has made it simple to add new controls. Here’s how I used it plus a joystick to add UK horn control to my virtual train.| Christopher Mitchell, Ph.D.
In my ongoing quest to build a physical cab dashboard to control Train Simulator, an important set of components are the gauges that tell me what’s going on with the train. As I build the dashboard into which to embed my gauges, I realized I needed to better modularize my air pressure gauge, moving the control circuit board outside the gauge. Here’s how I did it.| Christopher Mitchell, Ph.D.
Having sporadically built controls and gauges to interface with Train Simulator over the course of a year, in April 2024 I began to figure out how to design the dashboard they would all fit into.| Christopher Mitchell, Ph.D.
For quite a few years now, I have been an avid Train Simulator player, operating virtual trains from the United States, the UK, and beyond. I’ve played Dovetail Games’ Train Simulator 2015 to 2022 and now “Train Simulator Classic”, FIFA-style annual upgrades that have incrementally improved the core game - and I’ve spent a decent amount of money on the much-memed Train Simulator DLC. The game is pretty immersive, but since part of my life also includes running real-life rail vehicle...| Christopher Mitchell, Ph.D.
