Paul:

Excellent work man!  This is a very good beginning to our understanding of these b-cap properties.  Thank you again.

@MrMag,

Repair radios, TV's, you name it, from a very early age. I remember when I was around 8 yrs. old building my cat whisker receiver. Probably have a hell of a time doing it now.

Another early starter, beautiful 

@ IST,
Could you please post the same image as the one on thread page 18, but put 2 side by side.
I have a reason, and will explain it when I see them.
I would do this myself but don't know how.

jim yes i will post some scope shots ...

i have better ones to discribe this in great deatail ..

i can post if you like and we can walk through it ...

perhaps it deserves it own topic...


if some one will make it i will post there might  be better to put it ..

as this is important truth ...

@ Paul,

A good result I see, well done sir.

Hi,

Here's the circuits. Hopefully there's no mistakes in the drawings.

Remember, the pins shown in the parallel port photo are as it appears directly from your computer, *not* from the cable. So you'll have to do some mirroring to figure out the correct pins.

The top circuit is what I used to measure the voltage directly across the UC. The 2nd circuit I used to measure the UC current during the charging phase. The 3rd circuit I used to measure the UC current during the discharging phase.

You can place the op-amp resistors to meet your requirements, depending how much gain you would like. Or if only need a 1-1 input from 0 to +5V, then you don't need to op-amps and you can go directly to the ADC chip.

You can use your favorite op-amps. I have a zillion op-amps, and it's funny to me because the LM741 worked just fine.

I used 12V for V+, and -12V for V-.  And +5V for the ADC0809 and 555 timer. BTW, you could easily get a much much better ADC for probably the same price, but this is the only one I could find at home. Somewhere around here I have a very expensive 170MHz 12bit ADC, but can't find it.

People can request the software exe file via email. That way I can always email them an update if there's a bug or additions. Give me a day to make sure it works on non MS Visual Studio PC's who might not have the required DLL's since it's not a static DLL build.

Regards,
Paul
