Project Brief: Stealth-Modified Automatic Parking Disc (Certified for Public Road Use in Germany) Project Goal: I want to technically modify a certified electronic parking disc approved for use in Germany (must have an official certification number and ECE approval), so that it continues to automatically update the displayed parking time even after the vehicle has been parked. This modification must be invisible and undetectable from the outside, meaning the device must look and behave like the original product to any observer or parking enforcement officer. Background: Standard electronic parking discs are designed to detect when a vehicle is turned off and then freeze the display at the next permissible half-hour mark. This allows parking enforcement to determine how long the car has b...
