555 Sound Transmitter. Unusual Design 2

Not satisfied with IC 555 design. Now I am going to exploit its Control voltage pin 5. This pin is used to give a controlled voltage to control the working of the Flip-Flop inside the IC. But if it is not used, it will be connected to the ground through a 0.01 disc capacitor. I am going to give a minute voltage into this pin. Let us see what happens.

Timer with a difference. Unusual Design 1

You know the working of 555 Timer and a number of circuits using the IC 555 are available. But I am experimenting with this unusual design. It will give more time delay than the usual 555 Monostable design which gives only maximum 3 minutes. See the trick.
