Electronic Dazer:  The Electronic Dazer is a modern, portable, personal-protection appliance. It generates hight potential energy to ward off vicious animals or other attackers. It is an aid to help exape from a potentially dangerous situation. the device develops about 2,000 volts. Higher voltages mabe be attained by adding aditional multiplier stages, but it should be noted that those stage will also increase the overal size of the unit.
The Dazer is very compact, being built into a small plastic case. It is powered by a single 9-volt battery, either NiCad or alkaline. (Editor's Note: the so-called 9-V NiCad actually provides only about 7.5V. Why? NiCad cells only give 1.25 per cell. 6 cells in a 9volt battery gives it 7.5V and so the Alkaline type would be a better choice).   (electronic construction project added 10/05)

Fun and Games with Transistor Astables:  This project is all about fiddling with devices. Often people jump into electronics at the integrated circuit (IC) level, wiring IC's up without much knowledge of what's going on underneath. This project doesn't involve any IC's, just a few discrete components. That doesn't mean it's boring as there's plenty to be gained by building this circuit and having a look at how it works.
