I volunteer at a train, trolley, and subway museum. As a non-authoritative, hobby project combining my love of trains, electronics, mapping, and data, I am building a LiDAR scanner to map and analyze the museum. After designing the initial hardware and software for a GNSS-enabled LiDAR scanner, I built and tested it at the museum.

I volunteer at a train, trolley, and subway museum, including working on restoration of full-sized rail vehicles and maintaining railway infrastructure. As a non-authoritative, hobby project combining my love of trains, electronics, mapping, and data, I am building a LiDAR scanner to create a 3D map of the museum, automatically identify tracks and overhead wire, and compute wire height and track gauge.

GSM-R is the latest secure way for UK train drivers to communicate with signallers (dispatchers) and other drivers. Modern UK trains have a Driver’s Control Panel (DCP) with a display and buttons, but to date, very few simulator builders have succeeded at integrating a functional GSM-R DCP into their simulators. Here’s how I managed it.

With the center console of my train simulator built, I rapidly modeled and fabricated prototypes of the four other panels.

After a cardboard prototype of the center console of my Class 80x simulator, I created a functional hardboard version and took it for a spin.

TPWS is a key safety system in UK trains, so my Class 80x cab needed a precisely replicated TPWS control panel.

My cardboard prototype of the central portion of a Class 80x dashboard allowed me to iterate to a laser-cut hardboard prototype.

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.

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.

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.
