Just realized its april fools day. got to prank some one today. or get pranked? My spelling is a joke.

George: I tried the cap and also using NPN. Unfortunately neither helped. I am going to try using a 741 opp amp to see if this will work. I believe that my very small voltage gain from the receiver will make the opp amp flip and trigger the 555. thats my guess and iam sticking with it...

George: I tried a cap and that did not work because there are no AC type signals involved with this circuit. The wireless receiver has a 1K circuit resistance that drops to 0 ohms when triggered. When hooked to the 555 at pin 2, the circuit pulls the voltage on pin 2 below trigger point and...

Trying to hook a receiver to my mono 555 circuit and i will not drop the voltage to trigger. the timer. Any ideas on how to drop the voltage on pin 2 from a electronic grounding pulse that will start the timer?
