To: High Voltage list Subject: Re: Switch-mode provide for bug zapper (fwd) You need the elements for the steel you intend to use. Differing kinds have totally different losses. You receive this from the mfgr. Digi-Key has some inexpensive IR sort emitters & detectors. Have the fly crawl a distance, like 4-6 inches inside the tube, and then, Official Zap Zone Defender he triggers the IR beam which controls the zapper. A small single ended NST works great for this software. The present will burn them right up. The fly hits the IR beam on the 1/2 mid-approach point which energizes a small grid in each route. The midpoint has a bit 2 inches lengthy with no grid. They turn into trapped and can't exit both direction without getting zapped. You could also use a 600 Ohm to 10K audio xmfr. They make nice HV sparks operating in a pulsed mode. If the time duration is brief, like 1-2 sec, they may also charge a cap rectified with a 1/2 wave diode in a short while interval. Then the charged cap waits for the fly. The charging cycle occurs each 5 minutes and is controlled by a 555 IC chip --- a small relay controls the ability section. You place sugar crystals within the tube and Official Zap Zone Defender at the end of the tube use a small glass take a look at tube so you'll be able to see your accumulated flies to adjust the time durations. The flies will accumulate and then attempt to go out the charged grid part. The one we've uses a traditional laminated iron, 50Hz transformer. I'd like, so I'm looking at making a switchmode version. 2) Ditto for Zap Zone sizing the parts for the snubber. HV rectification and that I'd need a string of excessive-pace diodes.
