Ok, firstly I was daft enough to think I could jump back into electronics after 10 years!

<p>I have the circuit mentioned above, it's being used on a "buzzing wire" game to make a long buzz every time the wire is touched.<p>The trigger (pin 2) is held high by way of a 100pF capacitor, the voltage is 9V. It's triggered by touching the wire and allowing the capacitor to discharge through you.<p>
![Surprised :eek:](./images/smilies/icon_surprised.gif)
The problem is that is goes off all the time by bizarre acts such as walking past it - must be static.<p>

The question - how can I desensitise this circuit? Any help is greatly accepted.<p>I have tried using a resistor (1K) in series with the trigger, but this stopped it working completely.
