To: High Voltage record Subject: Re: Switch-mode supply for Zap Zone Defender Setup bug zapper (fwd) You need the elements for the steel you intend to make use of. Differing types have completely different losses. You obtain 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 software. The current will burn them right up. The fly hits the IR beam at the 1/2 mid-manner level which energizes a small grid in each path. The midpoint has a piece 2 inches long with no grid. They turn out to be trapped and cannot exit either path without getting zapped. You would additionally use a 600 Ohm to 10K audio xmfr. They make good HV sparks working in a pulsed mode. If the time duration is brief, like 1-2 sec, they might additionally charge 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 happens each 5 minutes and is managed by a 555 IC chip --- a small relay controls the ability part. You place 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 regulate the time intervals. The flies will accumulate after which attempt to go out the charged grid part. The one we've got makes use of a standard laminated iron, 50Hz transformer. I'd like, so I'm looking at making a switchmode version. 2) Ditto for sizing the elements for the snubber. HV rectification and that I'd need a string of high-speed diodes.



Dynatrap makes insect traps that work on the identical principle as others. They appeal to flying bugs with warmth and carbon dioxide, then catch them and prevent them from escaping. For warmth, they use a fluorescent extremely-violet bulb, which additionally emits bug-attracting light. The primary difference is that they don’t use propane to create carbon dioxide (CO2). Instead, they use a special process. More on that under. Since they don’t use propane, meaning no want to purchase and change cylinders, and best of all, no upkeep issues with clogged traces or failure of the propane to mild-issues that bother many different traps. You still need to plug them in, so you’ll need an outdoor outlet and an extension cord if you need grasp the trap more than 7-10 feet from the outlet. The DT2000XL mannequin is costlier than the DT1000 model, however it’s bigger, with a stronger fan and bright light, and can appeal to bugs from farther away, with coverage up to an acre for the DT2000XL and a half-acre for the DT1000, in line with the manufacturer.



If you’ve undoubtedly decided not to buy a propane mosquito entice, this is the next smartest thing. I’ll listing the pros and cons of the 2 models collectively, because they’re related. Its initial value is cheaper than propane traps. It doesn’t require the hassle and expense of changing propane tanks. It catches different bugs in addition to mosquitoes, though that’s not all the time good if they’re beneficial ones. You can use it indoors or outdoors. The one sound is the quiet humming of the fan and there’s no odor. It’s secure for pets, kids and the atmosphere, because it makes use of no insecticides. The big one: it doesn’t necessarily kill mosquitoes specifically, so it's possible you'll get extra moths or other things as a substitute. You’ll have to mount it about 5 to 6 ft off the bottom. One model, the DT1200, comes with its personal hanger, however in any other case, it needs a tree department, post, wall, fence, and so on. to dangle or sit on.



If you employ it outdoors, it may need some rain shelter to stop water from stepping into the gathering space. It wants an outlet 7-10 ft away or an extension cord. It’s tricky to empty without letting some bugs escape. The declare that it emits an efficient amount of CO2 has been questioned. Like all traps, it wants placed in a good location, shady and sheltered, the place mosquitoes can discover it, but not where you’ll be bothered by them. The lights in the top of the lure emit warmth and ultraviolet rays, which entice mosquitoes as well as different insects, notably moths at night. There are openings beneath the lights where bugs can fly in. Once inside, they’re sucked down by the fan’s air currents into the retaining cage below, the place they’re unable to flee and die inside a day. Unfortunately, Zap Zone Defender Setup gentle and warmth are simply two of the issues that appeal to mosquitoes, since what they’re mainly searching for are folks to bite.



Carbon dioxide is what they really seek, since we and other animals emit it when we exhale. Mosquitoes know that if they observe that vapor path, there shall be a tasty animal on the opposite end, ready to be bitten. To supply carbon dioxide, the Dynatrap makes use of a broad type of funnel above the fan, coated with titanium dioxide (TiO2). The producer claims that when the ultraviolet light reacts with the TiO2, "a photocatalytic reaction takes place that produces carbon dioxide." This is the process it uses, instead of burning propane like different traps. However, when the University of Wisconsin tried to measure the amount of carbon dioxide emitted, they reported that they detected none at all. One reviewer identified that the TiO2 floor would need coated with a supply of carbon, like mud or useless bugs, to ensure that the method to make carbon dioxide. See the assessment here (scroll all the way down to Dr. Marsteller’s remark).
