Pump Up The (Windows) Volume With Physical Sliders

For as long as we can remember, Windows has provided a mixer that breaks out the volume level of every applicable application into its own slider-controlled lane. But navigating to these controls is non-trivial, especially if you’re in a hurry to silence someone on team speak. You have to stop what you’re doing, click the speaker, go into the mixer, and then go find the appropriate slider. Windows won’t respect resizes between mixer visits, so you’ll almost always have some horizontal scrolling to do.

So why on Earth would you put yourself through all of this when you could be pushing physical sliders on the fly like a DJ? A slider is just a potentiometer in a straight line, after all.

These are wired up to an Arduino Nano, which sends the serial data to a Python script on the PC that changes the volume values accordingly for whatever five programs are in the config file. Thanks to a little bit of Visual Basic, the Python script can run in the background.

[Aithorn]’s got everything you need to replicate this, so slide on over and grab the STL files and code. If you get to point where these sliders are too small, just build some bigger ones.
