Hi Jack,
I have double checked and quadruple checked. I can get the circuits to work fine on a bread board. As soon as I transfer them, one component at a time, to the circuit board the circuit no longer functions properly. Tonight must have been my eighth attempt. You would think I would get it right just by chance. I know the circuit so well I can almost do it without looking at the schematic. My only guess is that there seems to be some kind of voltage issue with the components soldered onto the board. I actually removed all of the components one by one, off of a circuit board and transferred them back to the bread board. Everything again worked just like it should.
I Also checked for shorts in my soldering. Everything OK there too.
Go Figure????

Check you solder connections closely sometimes a solder connection will become intermittent. Are you using a circuit board?

Blood Electrifier Problem:
My LM358 IC chips arrived in the mail and I was finally able to complete my blood electrifier.
My construction followed Beck's solid state schematic without alterations. It seemed to work
fine initially, how ever an hour into the first treatment the LED quite fluctuating between red
and green and seemed to stay solid red.
What seems to be happening is that the polarity is changing so fast that the eye can't see the
change and the LED appears to be solid red. However If I wave the LED back and forth in front
of my eyes, both a green and a red light can be seen.
It would appear that somehow the timing has gone screwy. I'm wondering if maybe the
ceramic capacitor is faulty. I tried using another IC chip and that did not make a difference.
The batteries are new.
Ideas Anyone?
Thanks
