Timing flash circuit driven by field effect transistor

(1) Introduction to the circuit principle The circuit requires only a few components to form a timing control circuit for circulating light. The circuit includes a MOS time base
circuit 7555, a CMOS decimal counter (pulse distributor) 4017 and the final VMOS power field effect Crystal camp composition.

flow is flowing. The frequency of the time base circuit is adjusted by the potentiometer RP (about 10Hz above 0.S). The 9-bit loop r is
controlled by the output signal, so that each output signal becomes high or low. Since the @ foot is connected to the @ braid position llftA,9X, the 10th pulse does not cause the marrow to re-control
