CGO 08 Mic Power Supply CW Multiplier

Procrastinitis struck THRICE in the making of this video. First, when getting around to filming it. Next, when getting around to editing it together. And FINALLY when getting around to finally uploading it. LOL.

I talk about the Cockcroft-Walton voltage multiplier in my microphone's phantom power supply in this video, and explore a few experimental variations of it to see how it gets its interesting output voltage!

EEVBlog also has a pretty good video about CW multipliers: https://www.youtube.com/watch?v=ep3D_LC2UzU
And relevant Wikipedia article: https://en.wikipedia.org/wiki/Cockcroft%E2%80%93Walton_generator
And a another relevant article I used on the web to help me understand CW multipliers just a bit better as well: http://blazelabs.com/e-exp15.asp

CW multipliers are just a little bit of electrical black magic to me, at least in terms of how they actually work. But they somehow work. And I'm impressed that such a simple power supply circuit is what powers my condenser mic.

And in the background of the sidenote at the end you can hear our pet noisemaker Ruffles. He likes attention and when he doesn't get enough of it he makes sure the entire house knows about it. lol

Also, the reason my oscope couldn't track a steady signal in the sidenote is because I didn't know at the time that the trigger was set to source from channel 1 which wasn't even in use at the time, so it couldn't get a steady fix on the AC waveform. Gotta make sure your trigger is set to source from the channel you want to get a fix on! Otherwise you just get jittery, jumpy, useless rubbish on the screen!
