Hi, I have built the 2hz oscillator below, but using the mc14060b 14 bit counter, and my Vcc is 5V, not 12V.
I got the schematic here: http://www.reuk.co.uk/Making-Very-Accurate-Timers.htm
I connected it exactly as in the schematic on a breadboard, but noticed that my LED at the output is blinking faster than 2hz. I began to try things to fix it, and noticed that if I take the crystal and capacitors out of the circuit the LED is still blinking the same way. Turn power off and back on, still blinking. What the heck is going on LOL?
I think it might be noise going to the clock input of the counter that is causing this. The crystal seems to be doing nothing. Our own member retched has connected this circuit before and said he got it to work. I don't understand why its not working. Please help guys.
