I need some help designing a circuit which runs on a 9v battery and gives moderate shocks. i have a bronze 'round peg' and a bronze 'square hole'. when i try to place the round peg into the square hole, when the two make contact, i want to be given a minor shock. i have found some designs for shocker circuits on the internet and in this forum, but they all require a pushbutton switch and a delay in the delivery of the shock. i need a shock which is delivered at the moment of contact.
