556 problems



Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Fucian-at-aol-dot-com>

Hi all, i am having some freaky 556 timer problems.I am using a standard 556 
and using one timer to pulse the second timer.They both are in 50% duty cycle 
mode.It seems to work fine when on the solderless breadboard but once i 
solder it all too a Radio Shack IC board, it doesnt work right.The voltage is 
like 8 volts out with a 14volt regulated supply.WHY!??Both timers use bare 
miniumum components.A pot and a timing capacitor each.The output of the 
staccato one goes to the reset pin of the second timer.The output from the 
second timer goes to a totem pole transistor pair.What could be wrong?Ive 
triple checked EVERYTHING.Ive built and rebuilt the circuit several times on 
a new board each time.Maybe evil radio shack spirits?

Thanks,
Matt
