- I'll look to see if I still have the schematic or an article reference,
- but I built one of these once from an RE article, I believe. It used
- a real brute force approach: It was basically a small DC power supply,
- a 555 oscillator driving a nice big switching transistor, and an auto-
- mobile spark coil with high-voltage rectifier and capacitor. It worked,
- too. However, it generated a fair amount of heat, and was capable of
- delivering some hefty current, as I demonstrated when I put my fingers
- on the heat sink to see how warm it was and brushed against the output.
- Watched some fat, hot sparks dancing from my fingertips before I got
- away. In contrast, the little tower ion generator I got from DAK is
- high voltage but very low current and no shocks. Will post again if
- I actually find the circuit.
