No...the whole circuit is powered through the 90 ohm resistor.....Is the rest of the circuit connected directly to the supply (not through the resistor)?

I suspected as much when you saw no improvement.No...the whole circuit is powered through the 90 ohm resistor.....
Good detective work on that.I suspected as much when you saw no improvement.
The purpose of the resistor is to help isolate the 555 from the rest of the circuit.
The resistor must go only to the 555 circuit with everything else being powered directly from the supply.
