9V power? can we modify the circuit to use 5V instead?
can you make one so you can adjust the speed with a potentiometer?
Could I hook this up to an led array I have?
can you use another resistor instead of the two 220???
yes you can :-) but increasing the resistance will make the led flash slower, and decreasing the resistance will make the led flash quicker
you should use a potentiometer instead then, so you can adjust the flash speed ;)
