0.5 - 2048Hz 5VDC Pulse Generator

A digital pulse generator for testing digital circuits, especially digital clocks.
Very useful combined with a 5VDC power supply.
Update: Discarded "D3" from output while it gave interference at testing CMOS IC's, the output could pick up noise while it was low. A resistor (10k) to ground wil also solve that problem. Added R16 (10k) between SW1/13 and ground, to prevent "racing" between two positions when switching over.
