content: Imagine how funny the arduino remark was 4 years ago, when he first published the comic in 2010 and the arduino was relatively new in the maker world.Also, the Alt text refers tothis comicBut surely most people here already know xkcd? Not? Better take a day to read the entire archive then, its the sort of nerdy humor that fits the people here, I am sure.

content: Quote from: Phaedrus on February 27, 2014, 04:05:13 amI would leave this for my students - and now I can blame youThis picture has been on my lecture slides for some years now, but never before I had the idea to look into this circuitYes with a piece of paper and probably after some Delta-Y transformations - it appears to be made for this purpose.But why bother? At least I tried to feed the circuit to Ltspice: 0.748 ohms - give or take some wrong connections...But I got another idea now

content: Here's a better quality link to the polish op ampNational Semiconductor: Polish Op Amp data sheetAnyone have a high resolution photo of the topic circuit?There have been times where I wish I could throw away my switching logic and pay a little midget to do turn off my transistors instead...
