ELAB is an electronics laboratory for students of Electrical Engineering at the Technical University of Aachen. In the ELAB, the students have many high-quality measuring devices, tools, a 3D printer and the LPKF ProtoMat E44 circuit board plotter at their disposal.

Recently, the students equipped an old train conductor’s lamp with the latest technology. The ProtoMat E44 has successfully contributed to one of the main components of the revised lamp: The new circuit board.

The original bulb itself was replaced with an LED bulb, and the battery was replaced with a lithium-ion battery that can be charged by either a micro-USB socket or by the solar module mounted on the back.
