AVR-Chat

Hi, Ralph 

>Seems risky to me. Its going to depend a lot on the nature of this wildly
fluctuating supply and short term changes >in voltage. Is the cost of a
$0.50 regulator with 20 volt zener on the input via a resistor really
excessive?

	I am also too worried to try it at something that needs to be fail
proof. I will probably go with a 2 stages shunt supply. A resistor and a
Zener on the first stage and a TL431 on the second one. I will sleep easier
having a "clean" power supply !
 
	But... I will still make some tests with the first board to see what
happens to the poor AVR with the power supply "jumping" all over the place
:-)
