Got a web page addy for more info on this?ThanksThanks for your kind words. I take a lot of pride in making my car truly mine. Sadly, sometimes too much pride -- it's an expensive addiction.I'll do the best I can to explain my two repellent devices. ● Deer Alert - This was the first one I purchased. It ran about $29.99 + S&H from a catalog called AutoSport (
http://www.autosportcatalog.com). It's made by Maxsa Innovations (
http://www.maxsainnovations.com/). It's a bit of a chore to work with though. Installation is pretty easy. It has your traditional two-wire setup: +12 and ground. The manufacturer recommends simply wiring the device directly to both terminals of the battery. More on that in a second... The device has 2 modes. "Ultrasonic" and "audible." The ultrasonic mode allegedly pulses ultrasonic tones to make smaller animals (though I'm told not deer, but I can't say that for sure) in the vicinity aware of the presence of your car. Theoretically, that should scare them off. I say allegedly because ultrasonic sounds are not audible by human ears - so I have no real way of verifying that it does what it says. You can tell when ultrasonic mode is on (which is all the time) because you hear a clicking, similar to that of a relay. But that is the device (once again, allegedly) sending out ultrasonic pulses. The second mode, audible, is not automatic, and has to be engaged each time you want to use it. How it engages is what makes this device a bit of a nuisance. Built into the device is a circuit that detects changes in voltage. When you connect the device to the battery, this internal circuitry detects changes in the voltage in the electrical system when the car goes from off to on (a car that is off has a charge of approximately 11-12V in it's system. A car that is running can have a voltage range anywhere from 12-14V flowing). To activate audible mode, what you do is turn the car on once. The device makes a whistle noise that signals it is alive and running. When you hear that noise, you shut your engine off. The device makes a downward whistle that signals the voltage decreased. Then you immediately start the car AGAIN, and if you time it right, audible mode kicks in. Audible mode is simply a repeated upward chirping noise. I've linked to an audio MP3 file so you can hear the whole process, from start to audible mode activation. (CLICK FOR AUDIO)You'll note it took me two times in this file to get it into audible mode. Usually you can get it the first time. It's all about timing.Now I tried to be creative and design my own circuit where I could trick the device and create a voltage drop without driving my engine nuts with the on/off approach. I used a few parts from Radio Shack, one of which was a 7812 voltage regulator. It takes the approximately 14V input of a running engine and outputs a steady 12V. I had a SPDT momentary pushbutton, which when pressed, activated the regulated circuity, and when released, switched back to regular car power. The circuit was shoddy, but worked for a while, though it crapped out after only a month or so.Here's my circuit installed inside my dashboard:The schematic:Once the circuit crapped out, and I became sick and tired of the whole engine stop/restart procedure, I just connected the alert to +12 directly, and settled for using it only in ultrasonic mode.● The Hornet - After I got aggrevated with the first device, I decided to continue my quest for a proven, reliable deer repellent device. I stumbled upon a device called "The Hornet," made by a company called XP3 Corporation. (
http://www.xp3hornet.com). I bought it from them directly via their website. This one looks, um, non-traditional. LOL! I call it my deer cannon:That's it installed under my car. This one was even easier to install than the first one because it's idiot proof. It comes prewired, with a weatherproof connector (looks just like a headphone jack and plug), as well as an inline fuse, and long enough wiring to run into the passenger cabin for wiring a switch (also included!) It could easily be installed in under 20 minutes. Of course, I did a bit of customization on that as well. This one has to be mounted in a specific manner. It must be installed at an angle of 45° to the road surface. The reason why is the Hornet relies on the road surface to reflect the sound waves and help carry the sound longer distances. It can be mounted behind a grille, but you need to make sure the grille is "open" enough to allow the sound to pass through unrestricted. If the grille slats are too close together, the sound will simply get refracted by the plastics and make the device ineffective. In that picture, I had it mounted under my bumper. However, after a few close calls with curbs while parking, I decided to move it at the ohio meet. It now resides next to my license plate. This device emits a steady tone that is audible by human ears. It sounds just like your typical off-the-shelf piezo buzzer, but it works from what I can tell. The idea behind it is not to scare deer off, but merely making them aware of your car's presence and stop before running into the road. Between the two of these, something seems to work. I rarely have deer darting in front of me anymore, and when I see them on the side of the road and slow down, instead of running into the road like they used to, they watch me very carefully. I usually pass by without them even moving.
YES!I still visit GenVibe periodically. I have not forgotten about my "original" family over here!
