Simple Integrator Multiplies 555 Delay Circuit Diagram

This is a Simple Integrator Multiplies 555 Delay Circuit Diagram. Long delay times can be derived from a 555 timer with reasonably sized capacitors if an integrator circuit is used.The capacitor's charging time with an integrator circuit can be much longer than with a conventional 555-timer configuration. See below circuit diagram.
