Why can't it be public? Years ago I suggested that if you designed a curve
tracer everyone would want to build it. How about now?

Come to think about it, I also suggested once that you should write a
textbook.

I was thinking the other day about an early-warning monitor for failing PC
power supplies. If the caps start to go, the output will have increased
ripple. Lots of critical systems could benefit from this, and I personally
would build a few to meet my own needs.

A small module could plug into the end of a power cable.

A small board could monitor the voltages on the PCI bus.

Reaching test points for the CPU supply is harder. Not sure if the PCI bus
could be used to monitor that.

Indeed. But several others have already done it, here's just two...

I'm reluctant to use a system to monitor itself. I'd be inclined to
use a battery-powered monitor... just a receptacle/plug in-line with
the power cable to the mother-board, with comparators to measure the
P-P ripple.

(Although my immediate pondering suggests that battery-powered
wouldn't be necessary.)

Then public would still be acceptable? Just providing the opportunity in
case the free client wishes it to remain private rather than, for
instance, posting it here?

I've got a neat diversion to calculate, though it's not really a two hour
problem:
Consider a push-pull Royer oscillator, consisting of two transistors and
an ideal centertapped choke, supplied from a constant voltage source V
with series inductance Ls. Determine all the voltage ratings necessary
(peak voltage on Ls, on the CT choke, transistors). Find the RMS output
voltage (end-to-end, so that a load could be connected across the choke).
Determine the inductance required for a specified ripple in Ls at
operating frequency F.

The ratings are all easy, but the last one is more interesting, as it has
(as far as I know) a transcendental solution.
