Yes, I see where you are going with this, modify the circuit so it can only get one pulse. Well I just soldered the additional parts in place, and guess what happened? Yup, red hot transistor, hardware doesn't fix it either. Sorry to disappoint you but I actually thought for a minute it worked, till I got against the transistor and saw the smoke. Finger will heal, transistor, well lets just say it didn't fair as well.
