Hi All!
New here but fascinated with electronics, but being a busy Dad and now Grandfather, need some help from this experienced crowd.
I drive a fair amount back and forth to work, mainly country roads and LOTS of wooded areas. I have had my encounters with deer, having one graze my car last year and want to minimize that if possible moving forward. I have a Hornet electronic deer alert http://www.xp3hornet.com/ installed and use it with what I think are good results, but I fear it is not aggressive enough and want more...
I have done lots of research and find that reading several studies that increasing my ultrasonic warning presence would be very beneficial.
My plan is to use two high power piezo tweeters http://www.parts-express.com/grs-pz1142-piezo-bullet-horn-driver-similar-to-ksn1142a--292-448 with a high power amplifier http://www.pyleaudio.com/sku/plam2300 and this IC chip http://myskunkworks.net/index.php?route=product/product&product_id=58
The amp is good to 30kHz and the IC chip has an ultrasonic output that sweeps to 25 kHz. The amo is 75 watts RMS per channel and the tweeters rated to 100W RMS.
The chip has four settings, so I am going to install a non-shorting rotary switch to ground between sound outputs to have some fun along the way. I don't want to use this maliciously, but the ultrasonic animal warning output is exactly what I need.
I have read on many sites that an inductor should be used inline with the tweeters for best protection and to convert the wave from square to sine?
Does anyone have a suggestion on what I should use with these components? I am lost on the inductor suggestion????
Thanks all! Lookout for my next project on my boat: Switching between powered amplifier outputs and speaker level outputs when at anchor to save battery power using 4PDT relay trickery
