To: High Voltage list 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 get hold of this from the mfgr. Digi-Key has some cheap IR kind emitters & detectors. Have the fly crawl a distance, like 4-6 inches contained in the tube, after which, 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-approach level which energizes a small grid in each path. The midpoint has a piece 2 inches lengthy with no grid. They change into trapped and can't exit both course without getting zapped. You could also use a 600 Ohm to 10K audio xmfr. They make good HV sparks operating in a pulsed mode. If the time duration is brief, outdoor bug zapper for camping zapper like 1-2 sec, they might also 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 happens every 5 minutes and is controlled by a 555 IC chip --- a small relay controls the power section. You put sugar crystals in 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 try to exit the charged grid section. The one we have uses a conventional laminated iron, 50Hz transformer. I'd like, so I'm taking a look at making a switchmode version. 2) Ditto for sizing the parts for the snubber. HV rectification and that I'd need a string of high-speed diodes.
Dynatrap makes insect zapper traps that work on the identical principle as others. They appeal to flying bugs with warmth and carbon dioxide, then catch them and forestall them from escaping. For warmth, they use a fluorescent ultra-violet bulb, which additionally emits bug zapper for camping-attracting mild. The principle distinction is that they don’t use propane to create carbon dioxide (CO2). Instead, they use a particular process. More on that below. Since they don’t use propane, which means no need to buy bug zapper and alter cylinders, and best of all, no maintenance problems with clogged strains or failure of the propane to mild-issues that bother many different traps. You continue to have to plug them in, so you’ll need an outdoor outlet and an extension cord if you would like cling the trap greater than 7-10 ft from the outlet. The DT2000XL model is more expensive than the DT1000 model, but it’s larger, with a stronger fan and shiny gentle, Zappify mosquito zapper and can appeal to bugs from farther away, with coverage as much as an acre for the DT2000XL and a half-acre for the DT1000, in line with the producer.
If you’ve undoubtedly determined not to buy bug zapper a propane Zappify mosquito zapper entice, this is the next neatest thing. I’ll listing the professionals and cons of the 2 models collectively, as a result of they’re related. Its preliminary cost is cheaper than propane traps. It doesn’t require the problem and expense of changing propane tanks. It catches other bugs besides mosquitoes, though that’s not all the time good if they’re beneficial ones. You should utilize it indoors or outdoors. The one sound is the quiet humming of the fan and there’s no odor. It’s safe for pets, youngsters and the atmosphere, since it uses no insecticides. The massive one: it doesn’t necessarily kill mosquitoes specifically, so you might get extra moths or other issues instead. You’ll need to mount it about 5 to 6 toes off the bottom. One model, the DT1200, comes with its own hanger, however otherwise, it needs a tree branch, submit, wall, fence, outdoor bug zapper and so forth. to hold or sit on.
If you employ it outdoors, it may have some rain shelter to prevent water from moving into the gathering area. It needs an outlet 7-10 toes away or an extension cord. It’s tricky to empty with out letting some bugs escape. The declare that it emits an effective quantity of CO2 has been questioned. Like all traps, it needs placed in a very good location, shady and sheltered, where mosquitoes can find it, but not the place you’ll be bothered by them. The lights in the highest of the trap emit warmth and ultraviolet rays, which entice mosquitoes as well as different insects, particularly moths at night time. There are openings beneath the lights the place bugs can fly in. Once inside, they’re sucked down by the fan’s air currents into the retaining cage under, the place they’re unable to flee and die inside a day. Unfortunately, light and warmth are just two of the things that attract mosquitoes, since what they’re mainly looking for are people to chunk.
Carbon dioxide is what they really search, since we and different animals emit it when we exhale. Mosquitoes know that if they observe that vapor path, there might be a tasty animal on the other finish, able to be bitten. To provide 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." That is the process it makes use of, instead of burning propane like other 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 surface would wish coated with a source of carbon, like dust or lifeless bugs, in order for the process to make carbon dioxide. See the assessment here (scroll right down to Dr. Marsteller’s comment).
