The Challenge of Upgrading Vintage Gauges with Modern Circuitry

Retrofitting Classic Gauges with Modern Electronics
The team at Bad Obsession Motorsport faced a unique challenge with the Austin Mini GT4’s original dashboard. Their goal was to maintain the classic appearance of the vintage gauges while upgrading the electronics to ensure reliable, modern functionality. This required careful planning to blend old components with new circuit elements in a way that retained the car’s vintage charm without compromising on performance.

Creative PCB Design
To overcome the limitations of outdated wiring, the team designed a custom circuit board tailored to fit behind the existing gauge setup. This DIY PCB not only replaced the old wiring but also ensured compatibility with the car’s vintage layout. The intricate work allowed the team to modernize the dashboard’s function, paving the way for improved reliability and functionality while keeping the original design intact.

The Ingenious 3D Printer Soldering Solution

Finding a DIY Solution for Circuit Tracing
When it came to creating traces for their custom PCB, the team encountered a roadblock. Instead of outsourcing the task to a fabrication service, they devised an in-house solution by repurposing a 3D printer to lay down solder traces. Noting the similar melting points of 3D printer filament and solder, they experimented with using the printer to place the solder directly, allowing them to complete the circuit board in a creative, cost-effective manner.

Benefits of the 3D Printing Approach
This innovative use of a 3D printer provided several advantages, from saving costs to enabling greater control over the project. The approach allowed the team to make on-the-fly adjustments, resulting in a clean and functional PCB with well-adhered solder traces. This method highlights the team’s resourcefulness and ability to find practical solutions, showcasing an inventive approach to DIY electronics.
