[sdiy] polarity switcher

[matti]

Why bother with such a (relatively) high-cost device? Wouldn't a simple
opamp suffice? Perhaps with an analog switch for CV control?


enjoy

I finally got to the toilet paper, but couldn't find the end of the roll.
I grabbed at the paper, clawing at it, but it felt like smoke. I
eventually managed to grab a fistful, and looking down at my hand, I
couldn't see anything, but I knew I had the paper. Somehow. I managed to
wipe, somehow, and while glancing down I noticed my legs had disappeared.
Oh, no, it's ok, there they are. No, they've gone again. How the fuck am I
supposed to wipe when my asshole keeps disappearing?
