To: High Voltage list Subject: Re: ZapZone Switch-mode supply for bug zapper (fwd) You want the elements for Zap Zone Defender the steel you intend to make use of. Differing kinds have different losses. You acquire this from the mfgr. Digi-Key has some inexpensive IR kind emitters & detectors. Have the fly crawl a distance, ZapZone like 4-6 inches inside 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 proper up. The fly hits the IR beam at the 1/2 mid-means level which energizes a small grid in every direction. The midpoint has a bit 2 inches lengthy with no grid. They turn into trapped and can't exit either course with out getting zapped. You could also use a 600 Ohm to 10K audio xmfr. They make good HV sparks working in a pulsed mode. If the time duration is brief, like 1-2 sec, they may also charge 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 ZapZone is controlled by a 555 IC chip --- a small relay controls the power part. You place sugar crystals in the tube and at the tip of the tube use a small glass check tube so you can see your accumulated flies to adjust the time periods. The flies will accumulate and then attempt to go out the charged grid section. The one we've got makes use of a standard laminated iron, 50Hz transformer. I'd like, so I'm taking a look at making a switchmode version. 2) Ditto for sizing the components for the snubber. HV rectification and that I'd need a string of high-speed diodes.

Dynatrap makes insect traps that work on the identical principle as others. They attract flying bugs with warmth and carbon dioxide, then catch them and prevent them from escaping. For warmth, they use a fluorescent ultra-violet bulb, which additionally emits bug-attracting light. The primary difference is that they don’t use propane to create carbon dioxide (CO2). Instead, they use a special course of. More on that under. Since they don’t use propane, meaning no need to purchase and change cylinders, and better of all, no upkeep problems with clogged strains 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 out of doors outlet and an extension cord if you want hang the trap greater than 7-10 ft from the outlet. The DT2000XL mannequin is more expensive than the DT1000 model, but it’s larger, with a stronger fan and vivid gentle, and may attract bugs from farther away, Zap Zone Defender Testimonial with protection as much as an acre for the DT2000XL and ZapZone a half-acre for the DT1000, in response to the producer.

If you’ve undoubtedly determined not to purchase a propane mosquito trap, patio insect zapper this is the subsequent best thing. I’ll record the professionals and cons of the 2 models collectively, because they’re similar. Its preliminary value is cheaper than propane traps. It doesn’t require the trouble and expense of changing propane tanks. It catches different bugs in addition to mosquitoes, although that’s not at all times good if they’re useful 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, children and the setting, since it makes use of no insecticides. The big one: it doesn’t essentially kill mosquitoes specifically, so you might get more moths or other things as a substitute. You’ll need to mount it about 5 to six feet off the ground. One mannequin, the DT1200, comes with its personal hanger, but in any other case, it wants a tree branch, submit, wall, fence, and many others. to dangle or sit on.

If you utilize it outdoors, it may need some rain shelter to forestall water from stepping into the amassing area. It needs an outlet 7-10 feet away or an extension cord. It’s tough to empty with out letting some bugs escape. The claim that it emits an effective amount of CO2 has been questioned. Like all traps, it needs placed in an excellent location, shady and sheltered, the place mosquitoes can discover it, ZapZone however not where you’ll be bothered by them. The lights in the highest of the trap emit warmth and ultraviolet rays, which attract mosquitoes in addition to different insects, significantly moths at night. There are openings beneath the lights where bugs can fly in. Once inside, they’re sucked down by the fan’s air currents into the retaining cage below, ZapZone the place they’re unable to escape and die inside a day. Unfortunately, ZapZone mild and warmth are just two of the issues that entice mosquitoes, since what they’re mainly in search of are individuals to chew.

Carbon dioxide is what they really seek, since we and other animals emit it when we exhale. Mosquitoes know that in the event that they follow that vapor trail, there will likely be a tasty animal on the other finish, able to be bitten. To supply 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 mild reacts with the TiO2, "a photocatalytic reaction takes place that produces carbon dioxide." That is the process it uses, 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 at all. One reviewer pointed out that the TiO2 floor would need coated with a supply of carbon, like dust or lifeless bugs, Zap Zone to ensure that the method to make carbon dioxide.
