One of my (too many) hobbies is also fiddling with electronics and audio stuff. I built a gamma2 DAC kit from AMB a while ago and soon I’m going to build tube headphone amp too. In the mean time I got an idea to make amplifier knobs, because there didn’t seem to be very many options to choose from. Mostly factory made aluminium knobs. What if I wanted titanium, stainless or bronze knobs? Didn’t find them anywhere.

So I made some myself.

Here is short video of how the engraving of that map knob was like. Source for engraving was some old simplified version of Earth’s map.
