Does this tutorial by RJD2 about how to build a modular synthesizer turn you on? No? What if I told you he's the guy who made the Mad Men theme song? Like, already there's that and then this song that I think is even better, plus the fact that he's from Ohio, but then he says stuff like, "On the left those are trimpots (the "pot" is short for potentiometer). They're like the exact same thing as the volume knob on your stereo. It's a variable resistor. If you have a 10K trimpot, that means if you turn it all the way one way it'll provide 10 K-ohms of resistance; if you turn it all the way the other way, it'll provide zero." Zero ohms of resistance.
