It's Hip to be Square-Wave
  Posted by: AceBHound on Apr 19th, 2011 7:55 PM
A little bit of oscilloscope humor. I'm new to the world of oscilloscopes but always wanted to play around with one. Finally ponied up some cash for an oscilloscope and wired up a quick square wave generator as found on the Stern SB-100 Pinball Sound Board -- an LM324 quad op amp, 4 resistors, 0.1uf capacitor and a potentiometer. It's pretty cool seeing a "square wave" for the first time, especially one that you created out of some electronic components. This electronic stuff is a bit like playing Frankenstein -- wire it all up and hope that in the end you can shout "IT'S ALIIIIIIVE!!" instead of seeing it go up in flames. So join me in welcoming my square wave into the world, even if he won't get much love for being so square!
