Claimed OU circuit of Rosemary Ainslie

Have a good one Hoppy!

I hope that on my return that this Ainslie COP17 Heater fiasco will be cooling off.

lol, ever the optimist

the "s-plane transfer function" for a given analog circuit has "poles" that lie in "the right half of the s-plane."

Indeed, I know it as the Z-plane coming from digital. Right hand poles introduce energy feedback leading to overdrive and often chaotic behaviour like the 555 instability problem. If all poles of every system node are plotted then usually left hand poles carry more weight and so it is lossy. If right poles dominate (when ALL system nodes are considered) then it is OU.

@TK,

To get a better measure on system COP (with regard to it being a heater) have you thought about having the FET in the calorimeter as well as the load?

@jibbguy: build the circuit for yourself and play around with it. You just "possibly" might learn something new about 555s. Never seen a partial failure? I have, many times. That's why I buy them by the dozen. Never seen anything but shorts to ground or Vcc, and just not working? I've seen much different failure modes than that. See the pic above for a fairly common one.
But we all know that I'm incompetent, so pay no attention to the evidence before your eyes.

so you poke fun when the "others" let the smoke out, but you admit to doing it all the time and that's fine with you and your sycophants. you "consume them like candy" as so noted by you "early on". more hypocrisy and cherry picking from the magnanimous ones.
