Getting my kicks asking electrical engineers to explain, verbally, how the Dual LED Flasher works; devilishly simplepic.twitter.com/av462BoDfU

@starsandrobots it's been amusing as well to see which circuit simulators can and cannot model it functioning. Depends on analog effects so
@starsandrobots simulators that treat every transistor as being perfectly identical fail to be able to model the behavior of this one
@starsandrobots so a ton of simulators model relaxation oscillators as having no output & you have to kickstart 'em with a brief transient
@starsandrobots I guess the people writing them forgot to add in the photoelectric effect. :P
@bofh453 well in this case the two transistors race to turn on and if they're perfectly identical, neither wins and you never get started
@bofh453 which is never the case IRL
