Hola colegas, alguien tendra el circuito de un ahuyentador ultrasonico de perros que funcione con pilas?
Gracias desde ya

This device utilizes ultrasonic sound waves to create a feeling of nauseousness in any humans within auditory range. It uses a high frequency oscillator to produce ultrasonic electrical waves that are amplified by transistors and converted to sound waves by a high frequency responsive speaker powered by only a 9 Volt battery. The basic kit and plans are available from http://www.amazing1.com for a mere $20 with shipping and i plan to purchase it very soon. It has a standard effective range of approximately 10 meters and I plan to put more transistors in my model so it at least doubles the range and effects on those within range.
The reason it works is very simple. The ultrasonic waves travel through the ear canal and pass through a region very close to the human equilibrium. The waves are such a high frequency that they cause resonance in the ear canal and it begins to severely vibrate the equilibrium, causing the sediment-filled liquid to slosh around a bit. It is this that causes a feeling of disorientation and quickly makes the victim(s) feel the sudden urge to vomit. It also causes dizziness, temporary vision problems, and possible mental disorders after prolonged exposure.
I hope to investigate infrasonic sounds as well, since certain frequencies are capable of causing death, bowel evacuation, and other interesting effects. To generate infrasonic sound, it is best to play two sounds at sonic frequencies that interfere, and create a net sound that is infrasonic. This allows you to use speakers that aren't infeasibly large to output decent amounts of infrasonic sound.
