Force Field


They say small things amuse small minds .... This is a 74-second impression of my latest electronic design. The concept is not new, but this is my own latest embodiment of it. OBSERVATION: Two oscillators run at 1 MHz each (one million cycles per second). Oscillator One feeds a counter, which counts from 0 to 15, over and over. Oscillator Two feeds a counter which kills the first counter, before it reaches 15. So Oscillator One never reaches 15 ... unless one slows down Oscillator Two. Then Oscillator One has a chance to get 15 under the wire -- and trigger an alarm. The presence of body capacitance slows down Oscillator Two.
