In the current quarter, three of my colleagues defend their dissertation. As a tradition, after a successful defense they receive a custom graduation cap (Doktorhut). This time I wanted to create something special and used my inspiration from Sven’s Epsilon badge from KTH’s electrical engineering chapter. The result is a blinking version of our logo.
I ordered the PCB from jlcpcb with black solder mask and reduced thickness of 0.6mm. The black PCB looks better than expected :)
