Morse pulse generator based on Monostable 555 circuit

[Miriax]

I drew inspiration for this project from this topic and this site.
This is my circuit diagram:

The pulse length varies as T = 1.1 × R1 × C1.
T = time period in seconds (s)
R1 = resistance in ohms
C1 = capacitance in farads (F)

I'm going for approximately a 0.125s cycle, probably less, so .125 ~> 1.1(20000)(0.0000047). I'll be using a 15k resistor with a 0-5k pot. I'm also allowing +/-20% because the 4.7uF capacitor is electrolytic.

I'm just starting out in electronics, but can anyone tell me if this circuit will do what I think it will? I want it to send a brief, timed pulse every time the key (trigger) is depressed. I think I've got the timing down, but who knows? I may not have the battery wired correctly.

Thanks, and I'll let everyone know how the circuit works once I put it together.

from what i knew the 7 and 6 pins should be hooked up to eachother.

the batery is wired wright.
Does it work properly now??
