To: High Voltage checklist Subject: Re: Switch-mode supply for bug zapper (fwd) You need the components for the steel you intend to make use of. Differing kinds have totally different losses. You acquire 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 current will burn them right up. The fly hits the IR beam at the 1/2 mid-way level which energizes a small grid in each path. The midpoint has a bit 2 inches long with no grid. They turn into trapped and Zap Zone cannot exit either path with out getting zapped. You might additionally use a 600 Ohm to 10K audio xmfr. They make nice HV sparks working in a pulsed mode. If the time duration is brief, like 1-2 sec, 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 happens each 5 minutes and is managed by a 555 IC chip --- a small relay controls the ability part. You put sugar crystals within the tube and at the top of the tube use a small glass test tube so you'll be able to see your accumulated flies to adjust the time intervals. The flies will accumulate and then try to go out the charged grid section. The one we've makes use of a standard laminated iron, 50Hz transformer. I'd like, insect zapper so I'm taking a look at making a switchmode model. 2) Ditto for sizing the parts for the snubber. HV rectification and Zap Zone Defender System that I'd need a string of excessive-pace diodes.

Dynatrap makes insect traps that work on the identical principle as others. They attract flying bugs with warmth and Zap Zone Defender System carbon dioxide, then catch them and stop them from escaping. For warmth, they use a fluorescent extremely-violet bulb, which additionally emits bug-attracting mild. The principle difference is that they don’t use propane to create carbon dioxide (CO2). Instead, they use a particular course of. More on that under. Since they don’t use propane, meaning no need to purchase and alter cylinders, and better of all, no maintenance issues with clogged traces or failure of the propane to gentle-issues that hassle many other traps. You still have to plug them in, so you’ll need an outdoor outlet and Zap Zone Defender System an extension cord if you would like hold the trap greater than 7-10 toes from the outlet. The DT2000XL model is more expensive than the DT1000 model, Zap Zone Defender System however it’s larger, with a stronger fan and Zap Zone Defender bright mild, and can attract bugs from farther away, with protection as much as an acre for the DT2000XL and a half-acre for the DT1000, according to the producer.

If you’ve definitely determined not to buy a propane mosquito entice, that is the subsequent neatest thing. I’ll checklist the professionals and cons of the 2 fashions collectively, because they’re related. Its initial price is cheaper than propane traps. It doesn’t require the problem and expense of changing propane tanks. It catches different bugs in addition to mosquitoes, though that’s not at all times good if they’re useful ones. You should utilize it indoors or outdoors. The only sound is the quiet humming of the fan and there’s no odor. It’s protected for pets, chemical-free bug control kids and the environment, since it makes use of no insecticides. The large one: it doesn’t essentially kill mosquitoes specifically, so you might get extra moths or different things as an alternative. You’ll must mount it about 5 to six ft off the ground. One mannequin, the DT1200, comes with its own hanger, however in any other case, it needs a tree department, post, wall, fence, and many others. to hang or sit on.

If you use it outdoors, it may have some rain shelter to stop water from stepping into the collecting space. It wants an outlet 7-10 feet away or an extension cord. It’s difficult to empty without letting some bugs escape. The claim that it emits an efficient amount of CO2 has been questioned. Like all traps, it wants positioned in a good location, shady and sheltered, where mosquitoes can discover it, however not where you’ll be bothered by them. The lights in the highest of the lure emit warmth and ultraviolet rays, which attract mosquitoes in addition to other insects, notably moths at evening. There are openings below the lights the place bugs can fly in. Once inside, they’re sucked down by the fan’s air currents into the retaining cage below, where they’re unable to flee and die within a day. Unfortunately, light and warmth are just two of the issues that appeal to mosquitoes, Defender by Zap Zone since what they’re mainly looking for are individuals to chew.

Carbon dioxide is what they really seek, since we and other animals emit it when we exhale. Mosquitoes know that if they comply with that vapor trail, there might be a tasty animal on the opposite end, ready to be bitten. To supply carbon dioxide, the Dynatrap uses a broad sort of funnel above the fan, coated with titanium dioxide (TiO2). The manufacturer claims that when the ultraviolet mild reacts with the TiO2, "a photocatalytic reaction takes place that produces carbon dioxide." This is the method it makes use of, as an alternative of burning propane like different traps. However, when the University of Wisconsin tried to measure the quantity of carbon dioxide emitted, they reported that they detected none in any respect. One reviewer identified that the TiO2 floor would need coated with a source of carbon, like dust or useless bugs, to ensure that the method to make carbon dioxide. See the assessment right here (scroll down to Dr. Marsteller’s comment).
