Re: Switch-mode Supply For Bug Zapper Fwd

To: High Voltage list Subject: Zap Zone Defender Setup Re: Switch-mode provide for bug zapper (fwd) You need the elements for the steel you intend to make use of. Different types have totally different losses. You get hold of this from the mfgr. Digi-Key has some cheap IR type emitters & detectors. Have the fly crawl a distance, like 4-6 inches inside the tube, after which, he triggers the IR beam which controls the zapper. A small single ended NST works great for this application. The current will burn them proper up. The fly hits the IR beam on the 1/2 mid-manner level which energizes a small grid in each direction. The midpoint has a section 2 inches lengthy with no grid. They develop into trapped and cannot exit both path without getting zapped. You would additionally use a 600 Ohm to 10K audio xmfr. They make nice HV sparks operating in a pulsed mode. If the time duration is short, 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 happens each 5 minutes and is managed by a 555 IC chip --- a small relay controls the ability part. You set 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 periods. The flies will accumulate and then try to exit the charged grid section. The one we have now makes use of a standard laminated iron, 50Hz transformer. I'd like, Zap Zone Defender Setup so I'm taking a look at making a switchmode model. 2) Ditto for sizing the parts 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 appeal to flying bugs with warmth and carbon dioxide, then catch them and prevent them from escaping. For warmth, they use a fluorescent ultra-violet bulb, Zap Zone Defender Testimonial which also emits bug-attracting light. The primary difference is that they don’t use propane to create carbon dioxide (CO2). Instead, they use a particular process. More on that under. Since they don’t use propane, meaning no need to purchase and change cylinders, and better of all, no upkeep issues with clogged traces or failure of the propane to mild-points that bother many other traps. You still have to plug them in, so you’ll need an outdoor outlet and an extension cord in order for you dangle the lure more than 7-10 feet from the outlet. The DT2000XL model is more expensive than the DT1000 model, but it’s bigger, with a stronger fan and brilliant light, and may appeal to bugs from farther away, with coverage up to an acre for the DT2000XL and Zap Zone Defender a half-acre for the DT1000, in line with the producer.



If you’ve undoubtedly determined not to buy a propane mosquito trap, Zap Zone Defender Testimonial that is the subsequent neatest thing. I’ll record the pros and cons of the 2 models collectively, as a result of they’re comparable. Its preliminary price is cheaper than propane traps. It doesn’t require the problem and expense of changing propane tanks. It catches different bugs apart from mosquitoes, though that’s not at all times good if they’re beneficial ones. You can use it indoors or outdoors. The only sound is the quiet humming of the fan and there’s no odor. It’s secure for pets, children and the surroundings, because it uses no insecticides. The large one: it doesn’t necessarily kill mosquitoes specifically, so you might get more moths or different issues instead. You’ll must mount it about 5 to six ft off the ground. One mannequin, the DT1200, comes with its personal hanger, but otherwise, it needs a tree department, post, wall, fence, and many others. to grasp or sit on.



If you use it outdoors, it may need some rain shelter to stop water from getting into the accumulating space. It needs an outlet 7-10 ft away or an extension cord. It’s difficult to empty without letting some bugs escape. The claim that it emits an efficient quantity of CO2 has been questioned. Like all traps, it wants placed in a great location, shady and sheltered, where mosquitoes can discover it, however not where you’ll be bothered by them. The lights in the top of the entice emit warmth and ultraviolet rays, which entice mosquitoes in addition to different insects, significantly 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 escape and die inside a day. Unfortunately, light and warmth are just two of the things that entice mosquitoes, since what they’re primarily on the lookout for are individuals to bite.



Carbon dioxide is what they actually seek, since we and different animals emit it once we exhale. Mosquitoes know that in the event that they follow that vapor trail, there shall be a tasty animal on the other 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 producer claims that when the ultraviolet mild reacts with the TiO2, "a photocatalytic response takes place that produces carbon dioxide." That is the method it uses, 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 mud or lifeless bugs, to ensure that the process to make carbon dioxide. See the evaluate here (scroll all the way down to Dr. Marsteller’s remark).
