Caterham Sevens · Motorsport & telemetry · Embedded electronics · Practical engineering
Real builds. Real track days. Real data.
Caterham7Diaries brings together the engineering projects behind Caterham 7 Diaries, an independent enthusiast website documenting Caterham Seven ownership, builds, upgrades and time on the road and track.
Alongside the stories and technical write-ups are the software and electronics projects: instrument displays, ECU and CAN-bus investigations, lap and session timing, GNSS, microcontrollers, connected sensors and 3D-printable hardware. This is the place for the code, wiring, prototypes and development notes behind those ideas.
Built for the Seven. Engineered for the drive.
| 🏎️ Caterham & vehicle data | ⏱️ Motorsport & GNSS | 🛠️ Hardware & fabrication |
|---|---|---|
| Caterham ECU communication, CAN-bus captures, dashboards and vehicle telemetry | Session countdown systems, standalone GPS timing, GNSS diagnostics and IMU integration | Raspberry Pi / ESP32 / Pico projects, sensor dashboards, connected devices and OpenSCAD parts |
|
A standalone track-day timing and GNSS lap-time project with an AMOLED display, IMU data and session logging. Hardware testing is in progress. 
|
The original MicroPython-based track-session timer, designed around high-visibility countdowns and information you can read at a glance. 
|
|
CAN-bus captures and protocol analysis tooling for understanding MBE ECU communications on Caterham Seven models. 
|
An experimental Caterham dashboard for Raspberry Pi, visualising vehicle information received from the ECU over a network connection. 
|
🛰️ NEO-M9N CLILinux diagnostics for the u-blox NEO-M9N GNSS receiver, including live navigation data and connectivity troubleshooting. 
|
🏎️ F1DashAn earlier Raspberry Pi telemetry display experiment using the F1 2016 game’s UDP data stream. An archive-style project illustrating where the dashboard ideas began. 
|
| Project | What it explores |
|---|---|
| Zigbee Border Gateway Env | Local-first Zigbee coordinator, API and dashboard using ESP32 and Linux |
| Pico Sense Environment | Pico WH-based environmental sensing, display and web API |
| 3D Printing SCAD | Parametric OpenSCAD models, printable parts and fabrication notes |
| Pond Pico Controller | Network-accessible temperature monitoring and control for a pond |
The Caterham 7 Diaries website tells the other half of the story: building and maintaining the car, making modifications, documenting lessons learned and enjoying the roads and circuits. You'll also find occasional writing about other enthusiast cars.
