To: High Voltage checklist Subject: Re: Switch-mode supply for bug zapper (fwd) You want the components for the steel you intend to make use of. Differing types have totally 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, Zap Zone Defender 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-means point which energizes a small grid in each route. The midpoint has a piece 2 inches lengthy with no grid. They change into trapped and can't exit both course with out 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 brief, like 1-2 sec, they might additionally cost a cap rectified with a 1/2 wave diode in a short time period. Then the charged cap waits for the fly. The charging cycle occurs each 5 minutes and is managed by a 555 IC chip --- a small relay controls the facility part. You place sugar crystals in the tube and at the top of the tube use a small glass check tube so you'll be able to see your accumulated flies to regulate the time durations. The flies will accumulate and then try to go out the charged grid section. The one we now have uses a standard laminated iron, Zap Zone Defender 50Hz transformer. I'd like, so I'm taking a look at making a switchmode version. 2) Ditto for sizing the elements for the snubber. HV rectification and Zap Zone Defender that I'd need a string of excessive-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 forestall them from escaping. For warmth, they use a fluorescent ultra-violet bulb, which also emits bug-attracting light. The main distinction is that they don’t use propane to create carbon dioxide (CO2). Instead, they use a special course of. More on that beneath. Since they don’t use propane, that means no need to purchase and alter cylinders, and best of all, no maintenance problems with clogged traces or failure of the propane to mild-issues that hassle many different traps. You continue to need to plug them in, so you’ll want an outside outlet and an extension cord if you'd like cling the entice more than 7-10 feet from the outlet. The DT2000XL mannequin is dearer than the DT1000 model, but it’s greater, with a stronger fan and shiny gentle, and might entice bugs from farther away, with coverage up to an acre for the DT2000XL and a half-acre for the DT1000, Zap Zone Defender in accordance with the producer.
If you’ve definitely determined not to purchase a propane mosquito trap, that is the next neatest thing. I’ll list the pros and cons of the 2 models collectively, Zap Zone Defender as a result of they’re similar. Its initial value is cheaper than propane traps. It doesn’t require the problem and expense of replacing propane tanks. It catches other bugs moreover mosquitoes, though that’s not always good if they’re beneficial ones. You need to use it indoors or outdoors. The only sound is the quiet humming of the fan and there’s no odor. It’s safe for pets, children and the setting, since it uses no insecticides. The big one: it doesn’t necessarily kill mosquitoes particularly, so it's possible you'll get more moths or different issues as an alternative. You’ll have to mount it about 5 to six feet off the ground. One mannequin, the DT1200, comes with its personal hanger, however in any other case, it needs a tree branch, put up, wall, fence, and so on. to hang or sit on.
If you use it outdoors, it may have some rain shelter to stop water from stepping into the amassing area. It wants an outlet 7-10 toes away or an extension cord. It’s difficult to empty with out 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, Zap Zone Defender but not where 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 other insects, particularly moths at night. There are openings under the lights the place bugs can fly in. Once inside, they’re sucked down by the fan’s air currents into the retaining cage beneath, where they’re unable to flee and die within a day. Unfortunately, light and warmth are simply two of the things that entice mosquitoes, since what they’re mainly on the lookout for are people to chew.
Carbon dioxide is what they actually search, Zap Zone Defender since we and other animals emit it once we exhale. Mosquitoes know that if they comply with that vapor trail, there can be a tasty animal on the other end, ready to be bitten. To provide 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 response takes place that produces carbon dioxide." This is the process it makes use of, as an alternative 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 pointed out that the TiO2 surface would want coated with a source of carbon, Zap Zone Defender like mud or dead bugs, in order for the process to make carbon dioxide. See the evaluation here (scroll down to Dr. Marsteller’s remark).
