Greetings.
I built this circuit on a bread board and it worked with my power supply (no battery test as I assumed it would work). So then I built 3 identical circuits on solder board, see picture attached, and they all work with my little bench top power supply but not with a battery. Each unit does the same thing [including the bread board now that I've tried it], it works as desired on the P.S. (5-9VDC) continuously... but when I put it on a battery the flashes speed up until they are constant on.
Can anyone please tell me:
(1) why my circuit works with a 9VDC power supply and not with a 9VDC battery, and
(2) how can I make this work with a standard 9VDC battery?
Thank you
