Parody Circuits

I ran across this most excellent xkcd comic the other day:

Circuit Diagram
A funny circuit diagram parody

It’s just so funny on so many levels, if you’re a EE.  Let’s just go clockwise around the page, starting at the top left.

  • I love that the battery voltage is a square root.  Just so obscure and mathematically nerdy.
  • Gluing open the switch?  Ha!
  • That PNP transistor has two emitters, look out!  Crashing electrons!
  • I like that the printed value of the resistor isn’t explicit; just the color code is written.  Priceless.
  • Solder blob, yes!  Any engineer worth his salt relies on solder blobs during prototyping. It’s especially funny that this blob is shorting out a bunch of parts.
  • 666 timer.  Why didn’t I think of that one?  The 555 timer has had too much fun for too many years.
  • Magic smoke bottle.  Again, just so funny.
  • Just try to do some nodal analysis on that resistor network!
  • Holy water, tear collectors, and sandals… wow.
  • “Hire someone to open and close switch real fast.”  I laugh out loud each time I read that.
  • Most expensive chip available — I used one of those in my senior design project!
  • Arduino for blog cred.  That’s so trending now.
  • I’m afraid that 50V battery isn’t going to last long.
  • Hot glue.  Man, if I had a nickel for every time I whipped out the hot glue gun…

Insider parodies like these really crack me up.  I’m reminding of the Death Waltz musical score, also comically brilliant in its absurd complexity.  My wife reminded me of some music that her choir performed by ” PDQ Bach” {1}.  Here’s a delightful such performance:

In the professional world, it’s always good to have a sense of humor with regard to your work, whether it be circuit design or classical music.

Footnotes:

  1. P. D. Q. Bach is a fictitious composer invented by musical satirist “Professor” Peter Schickele. In a gag that Schickele has developed over a five-decade-long career, he performs “discovered” works of the “only forgotten son” of the Bach family. []
