To: High Voltage record Subject: Re: Zap Zone Defender Switch-mode supply for bug zapper (fwd) You want the factors for the steel you intend to use. Differing types have totally different losses. You acquire this from the mfgr. Digi-Key has some cheap 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 great for this application. The current will burn them right up. The fly hits the IR beam on the 1/2 mid-manner point which energizes a small grid in every route. The midpoint has a bit 2 inches lengthy with no grid. They become trapped and Zap Zone Defender can't exit both route without getting zapped. You may additionally use a 600 Ohm to 10K audio xmfr. They make nice HV sparks working in a pulsed mode. If the time duration is short, like 1-2 sec, they could 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 in the tube and Zap Zone Defender System at the top of the tube use a small glass test tube so you possibly can see your accumulated flies to regulate the time intervals. The flies will accumulate and then try to go out the charged grid part. The one we have 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 components for the snubber. HV rectification and that I'd want a string of high-velocity diodes.
Dynatrap makes insect traps that work on the identical principle as others. They entice flying bugs with warmth and carbon dioxide, then catch them and stop them from escaping. For warmth, they use a fluorescent extremely-violet bulb, which additionally emits bug-attracting light. The main distinction is that they don’t use propane to create carbon dioxide (CO2). Instead, they use a particular course of. More on that below. Since they don’t use propane, that means no want to purchase and change cylinders, and better of all, no maintenance issues with clogged traces or failure of the propane to gentle-issues that bother many different traps. You continue to have to plug them in, so you’ll need an outside outlet and an extension cord if you need dangle the entice greater than 7-10 toes from the outlet. The DT2000XL mannequin is dearer than the DT1000 mannequin, however it’s larger, with a stronger fan and vibrant light, and Zap Zone Defender can appeal to bugs from farther away, with coverage as much as an acre for the DT2000XL and Zap Zone Defender a half-acre for the DT1000, Zap Zone Defender in response to the producer.
If you’ve undoubtedly determined not to purchase a propane mosquito entice, that is the next smartest thing. I’ll record the professionals and cons of the 2 fashions together, because they’re related. Its preliminary cost is cheaper than propane traps. It doesn’t require the hassle and expense of changing propane tanks. It catches other bugs apart from mosquitoes, although that’s not all the time good if they’re helpful 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 safe for pets, youngsters and Zap Zone Defender the setting, because it makes use of no insecticides. The big one: it doesn’t essentially kill mosquitoes particularly, so you may get more moths or different things as a substitute. You’ll need to mount it about 5 to six feet off the ground. One mannequin, the DT1200, Official Zap Zone Defender comes with its personal hanger, however otherwise, it wants a tree branch, publish, wall, fence, etc. to hold or sit on.
If you employ it outdoors, it may need some rain shelter to stop water from moving into the accumulating space. It needs an outlet 7-10 toes away or Zap Zone Defender an extension cord. It’s difficult to empty without letting some bugs escape. The claim that it emits an effective quantity of CO2 has been questioned. Like all traps, it needs placed in a great location, shady and sheltered, where mosquitoes can find it, however not where you’ll be bothered by them. The lights in the top of the lure emit warmth and ultraviolet rays, which entice mosquitoes in addition to different insects, significantly moths at night time. 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 beneath, the place they’re unable to escape and die within a day. Unfortunately, gentle and warmth are just two of the things that appeal to mosquitoes, since what they’re primarily looking for are folks to chunk.
Carbon dioxide is what they actually seek, since we and other animals emit it after we exhale. Mosquitoes know that if they follow that vapor Zap Zone Defender trail, there will be a tasty animal on the other finish, ready to be bitten. To provide carbon dioxide, the Dynatrap uses a broad kind of funnel above the fan, coated with titanium dioxide (TiO2). The manufacturer claims that when the ultraviolet light reacts with the TiO2, "a photocatalytic reaction takes place that produces carbon dioxide." This is the method it makes use of, indoor-outdoor zapper as a substitute 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 at all. One reviewer identified that the TiO2 floor would need coated with a supply of carbon, like dust or dead bugs, to ensure that the process to make carbon dioxide.
