When I was a kid, I read a schemetic in a magazine that showed how to make a shock machine out of a transformer, a capacitor, a 9V battery and a push/release switch. At age 12 I was able to build one and had a great time shocking my friends (small but still startling). At age 14, I built an electric chair (a living room chair with foil wrapped on the arms, with a push button to deliver the shock) for halloween. At age 30, I'm trying to recall how I did it as a kid, and am having tons of trouble Any electrician minded people willing to help me with this halloween project? If I remember correctly, I hooked the leads of the 9V battery to the transformer (120V / 12.6V 1.2A transformer) and then hooked the leads on the other end of the transformer to a small capacitor (pinky tip sized cylinder). From the capacitor I hooked one lead through a push button switch and the other lead on an open circuit. Each lead terminated in a standard kitchen knife. The net effect is that you'd hold the kitchen knives as easy-grip conductors and then push the button. The current from the capacitor would be released into your body offering a small but shocking jolt. When I did it as an electric chair when I was a kid it was so much fun on Halloween! If anybody might be able to give me some pointers for refreshing my memory on this, I'd be much obliged! Andrew CC reply to edmond at aravia.com!
