To: High Voltage record Subject: mosquito-free patio Re: Switch-mode supply for bug zapper (fwd) You want the factors for the steel you intend to use. Differing types have 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 contained in the tube, and then, he triggers the IR beam which controls the zapper. A small single ended NST works great for this application. The present will burn them proper up. The fly hits the IR beam on the 1/2 mid-method level which energizes a small grid in every course. The midpoint has a bit 2 inches lengthy with no grid. They develop into trapped and mosquito-free patio cannot exit both course without getting zapped. You could possibly additionally use a 600 Ohm to 10K audio xmfr. They make nice HV sparks operating in a pulsed mode. If the time duration is short, like 1-2 sec, mosquito-free patio they might also charge a cap rectified with a 1/2 wave diode in a short time interval. Then the charged cap waits for the fly. The charging cycle occurs every 5 minutes and is managed by a 555 IC chip --- a small relay controls the power section. You set sugar crystals within the tube and at the end of the tube use a small glass check tube so you'll be able to see your accumulated flies to adjust the time periods. The flies will accumulate and then attempt to go out the charged grid section. The one now we have makes use of a conventional laminated iron, 50Hz transformer. I'd like, so I'm taking a look 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-velocity diodes.
Dynatrap makes insect traps that work on the same principle as others. They attract flying bugs with warmth and carbon dioxide, then catch them and fly zapper stop them from escaping. For insect zapper warmth, they use a fluorescent extremely-violet bulb, which also emits bug-attracting mild. The main distinction is that they don’t use propane to create carbon dioxide (CO2). Instead, mosquito-free patio they use a special course of. More on that beneath. Since they don’t use propane, that means no need to buy and change cylinders, and mosquito-free patio better of all, no maintenance issues with clogged lines or failure of the propane to light-issues that bother many other traps. You still need to plug them in, so you’ll need an outdoor outlet and an extension cord if you want cling the trap more than 7-10 feet from the outlet. The DT2000XL model is dearer than the DT1000 mannequin, mosquito-free patio however it’s greater, with a stronger fan and brilliant gentle, and might entice bugs from farther away, with coverage up to an acre for the DT2000XL and a half-acre for the DT1000, in accordance with the manufacturer.
If you’ve positively decided not to buy a propane mosquito trap, that is the next neatest thing. I’ll list the pros and cons of the two fashions collectively, as a result of they’re comparable. Its preliminary cost is cheaper than propane traps.
