When in college I initially took engineering specializing in electronics then did a course in are and design after that. It is always nice when I can use both disciplines on one job.
I am making a extra special pair of beyerdynamic custom one pro with LED light up earcups. To make it extra special we are making special clear plastic lenses with the name etched onto the back so it looks all 3d inside the perspex and allows the light from the LEDs to shine through in the right places.
Do do this I initially mocked up the design on the computher, then cut masks on our plotter cutter so I knew where everything was going to go as it all neede to line up for the laser engraving to look right. Then hand airbrushed the design in reverse on the back of the lens before sticking them in the laser engraver for a few passes at different heights to get the 3d effect.
Hopefully when they are finished they will look super awesome
