So.... I use automatic feeders to provide the deer with a steady supply of food, which helps keep them in the area. The problem is, that the raccoons have also discovered my feeders, and are doing a great deal of damage to them, trying to get the corn out faster than the pre-programmed rate I have the feeders set for. One feeder is now inoperable, and will cost nearly half it's original purchase price to repair. Let me be clear - I like Raccoons. As omnivores, I feel they serve an important function in the local ecology, and I don't want to hurt them. Alas, however, they are crafty, greedy by nature, and also destructive. I just want to teach them to leave my feeder alone. There's plenty spilled on the ground they can have, without trashing hundreds of dollars of equipment. There is something called a "Varmint Buster" on the market, which operates like an electric fence, or shock collar, but is the size of a deck of playing cards, and intended to protect only the vital workings on the feeder. If I understand correctly, it delivers a momentary shock, then resets. Unfortunately, it is proprietary, and no such device is available for the brand of feeders I own. I have dabbled in circuit design in the past, but that was all 12 volt, automotive applications. The Varmint Buster boasts a 2000 volt charge, and I THINK it is AC current, but I can not find information to verify that. It's power source IS a 6 volt DC battery. The biggest problem for me is that it does NOT say what amperage the device puts out, on any webpage I have found, so I am lacking some critical design specs. In fact, while every website selling them shows the control-pack, and 4 wires sticking out of it, I can not even find an example of it in use. Now, I am pretty sure that I could figure out how to design a workable 6 volt, solar recharged system, if only I had some clue what amperage I needed to target. After several hours of researching this product, dog collars, and electric fences, I am simply not finding any answers to my questions. So my main question is, "Does anyone know from experience or calculation how many amps, and/or which type of output current (AC vs. DC) I should be incorporating into the design?" Keep in mind that I want to surprise the Raccoons with a little sting, but not do any lasting harm. On the other hand, I'm probably not the first guy to consider a DIY project like this. Does anyone have a favorite website that might offer ready-made plans, that I could adopt, or modify to suit my purposes? If I don't have to reinvent the wheel, that would be just fine with me - I will get plenty of satisfaction from wiring and soldering it together from loose pieces. Here is something I found on Youtube, that serves a similar purpose, to keep squirrels out of bird feeders...It's kinda funny... Finally, please forgive me if I have used incorrect terminologies. I am entirely self-taught, and have not had any formal education in electronics. I understand the basics, and can learn what I need to accomplish a goal. Feel free to correct my errors, however. If I intend to play in your sandbox, I might just as well learn the language. Thank you for your patience. P.S. - anyone know the amperage on an electric flyswatter like the ones sold at Harbor Freight?
