/diy/ - Do It Yourself

Going to work on calculating values with the 555 chip tonight. Yes I wanted to add a pot, would that be in place of the voltage divider to the left of pic related?

Also I think 555 chips can take voltages between 4.5-15V, 18 being absolute maximum. Though it'd be pushjing it, I theorize my 12V 7.6A supply won't do harm to the chip.
