 		 #110912 - BC550 & diodes
Responding to: Kai Klaas's previous message
Kai Klaas said:

You could try this:


Yes i would.
But, willing to get few things clarified:

a) Kindly let me know about the use of BC550 and,
b) the purpose of the diodes in the circuit? (one at trigger and the other at reset pin)
