Bicycle lights are everyday safety devices – yet they are frequently stolen or inconvenient to remove and remount. KEEP.IT develops an innovative, theft-resistant bicycle light that combines a robust mechanical concept with smart electronics. The product already exists as a prototype; mechanical components are available and the focus of this thesis is entirely on electronics and embedded software.
The goal is to design an energy-efficient, robust, and series-ready electronic platform (PCB) including firmware for a rechargeable bicycle light: bright, reliable, and secure. The thesis is a paid company project with flexible working location and close technical exchange with the startup founder and university supervisors.
