Is this a "switch"?

That 555 inverter circuit you posted is neat. Do you have any idea what the -12 /volt maximum current output can be ?
Interested for use in an unrelated experiment.

Cheers

Is it just me, or is the most interesting thing discussed on this whole thread so far been the (redacted) that Tek's momma's working on?

Thanks, Hoptoad. You do realize that Rosemary thinks that you are me, or I am you, or something, right? Now she'll say we're both nuts because we talk to ourself.

No, I don't know what its max output is.  I'm still testing it.

As you might know (because it's there in plain sight on the board) I have a 0.3 ohm CVR in the bias circuit at the "FG+" input position, as well as the main CVR in the normal place. Here's a trace across that 0.3R CVR in the bias line, while running on the inverter circuit powered by the main battery, no external supply.
The baseline is indicated by the bright line (the other trace grounded and moved into position as a marker.) Horizontal is 2 microsec/div and vertical is 0.2 v/div.

Note that Rosemary again has claimed in no uncertain terms that the FG cannot put current into the system. This means, of course, that when her FG is set to produce the long-period, negative signal, causing the oscillations for minutes at a time, NO CURRENT flows from or to the FG to or from the circuit.

Right?

This is easily testable. Even Rosemary could test it. If she only had someone to hook it up for her and explain what the numbers mean.

We've already tested it for Tar Baby, haven't we? I can't recall if we did it using the FG alone or just with the external DC power supply. No matter.... we know that the Interstate F43 is a "magic" function generator already. So it shouldn't surprise anyone if it does manage to stuff current up Tar Baby somehow. But of course Ainslie's IsoTech 324.... which nobody can find on the internet anywhere..... can't do this at all, it only makes VOLTAGE.

Right?
