Re: IMPORTANT If You Are Going To Build A ZAPPER!

check this out... this web site I think is pretty informative.

"Clark gives easy-to-follow instructions for zapper construction in a shoe box using $20 worth of Radio Shack parts. There is no soldering or electronics knowledge necessary for construction. She also gives the schematic in " The Cure For All Diseases ",

but it is drawn incorrectly,

with the battery upside down and one of the capacitors shown the wrong value. Following or reading the idiotproof instructions and parts list will indicate the correct value for the capacitor and the polarity of the battery.

The idiotproof instructions are correct.

If one follows the schematic given in the book, the connections for the power and ground on the chip are assumed. One must connect pin 1 to ground and pin 8 to the switched wire. Do not connect pin 8 to the positive terminal of the battery or power will be applied to the chip even when the zapper is off.

Radio Shack once carried 555 CMOS chips but no longer does. The TTL ones are most commonly used, but it is better to use a CMOS 555 since the square waves are sharper, the harmonics richer, and it drains the battery less than a TTL version. Call electronic supply houses to find a CMOS 555 (sometimes called 7555..."
