To: High Voltage list Subject: Re: Switch-mode provide for Zappify Bug Zapper shop zapper (fwd) You want the elements for the steel you intend to use. Different types have completely different losses. You get hold of this from the mfgr. Digi-Key has some inexpensive IR kind emitters & detectors. Have the fly crawl a distance, like 4-6 inches inside the tube, and then, he triggers the IR beam which controls the zapper. A small single ended NST works nice for this utility. The present will burn them proper up. The fly hits the IR beam on the 1/2 mid-means point which energizes a small grid in each path. The midpoint has a bit 2 inches lengthy with no grid. They turn out to be trapped and can't exit either direction without getting zapped. You could also use a 600 Ohm to 10K audio xmfr. They make nice HV sparks working in a pulsed mode. If the time duration is short, like 1-2 sec, they could additionally cost a cap rectified with a 1/2 wave diode in a short while period. 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 part. You place sugar crystals in the tube and at the tip of the tube use a small glass take a look at tube so you'll be able to see your accumulated flies to regulate the time periods. The flies will accumulate and then try to exit the charged grid section. The one we've uses a conventional laminated iron, 50Hz transformer. I'd like, so I'm looking at making a switchmode model. 2) Ditto for sizing the elements for the snubber. HV rectification and that I'd need a string of high-speed diodes.
