I recently purchased a Roland Rubix22 USB audio interface second-hand for my PC, and being that it has XLR and 1/4 inch mic jacks, I thought it would be fun to have my hand at making a microphone. While looking into the different types of microphones that exist, I chose to try making a ribbon mic.

At my PC I usually use headphones and an FX-Audio DAC to listen to audio, but occasionally I will hook up my JBL partybox to play music with a speaker. The issue I was having was that the line level output from the DAC was at a fixed volume. So as a small, simple, 1 hour project, I made a stereo volume knob for the line level output.
