--- Yes, of course, if only to elicit the fun-ness of it through its utility.
A joke, for instance, is useful to its teller in eliciting laughter from an audience and sharing in the fun.
But, since you didn't flag your circuit as being a toy and you generally seem to want your stuff to be considered bulletproof, why are you surprised that the responses to your post were critical?

Oh, don't be do rigid. Build one of these and play with it. It does impressive things.

Which of your products is this "design" in ?:-)

Less fun, but here's a circuit I just laid out:-
The inverter is microscopic single-gate Schmitt trigger type and the p-channel MOSFET is half a dual.
Vin o------+-------+-------+-------+----+ | | | | | .-. | | | | R | | | | | | | | | | S | | '-' | ||-+ | / --- | |\\ ||-> - --- +------| >O--||-+ / ^ | | |/ | D | | .-. | | | | R | | | | | | | | ----------------+----+ '-' | | | | .-. | / | | | - .------. | | / ^ | | '-' | | LOAD | | | | | | === '------' === GND | GND | | === GND

My rule is... never use a floating gate! (Few exceptions.)
However ...I don't use IGBTs and don't know their gate dynamics.

That's just an n-ch mosfet. That's the way I draw them.
Um, what sort of machine are you using to connect to the internet? What sort of memory does it have? Sounds like roughly 10 billion "exceptions" right there.
Hmmm, what can we do with an spdt switch?
John
The circuit amused me for a while. What could be more important than that?
John
Them that are willing, yes.
John
Indeed!

Those are special floating gates designed to float in an IC :)
A floating wire connected to the gate of bigo mosfets (TO92 TO220) can act like an electrostatic antenna. No only that...but maybe..just maybe some circuit parasitics might do just the right phase shifting for all out oscillation.
Oh yeah... I draw my mosfets as 3 pin boxes...seems quicker.. D from BC

Clever :-) Keep button pressed for half on?
Aha. "It's not a bug, it's a feature!".
I like the mosfet symbol - I can't seem to keep the proper ones straight either :) I might start using it myself...
That's the symbol I use for IGBTs.

I think I've ssen it as an "April's Fool" circuit in Elektor eons ago.
robert
Yup, too busy and the arrow direction is annoying.
The emitter would be angled for an IGBT, I guess.
John
Oh, this works. And does interesting things.
John
Yup. Now, how does one get back to full on/off?
