Dog Repellent Ultrasonic Circuit
When we hear the word “Ultrasonic" we often refer it to bats and dolphins communication. Technically, “Ultrasonic" applies to sound that is anything above the frequencies of audible sound, and includes anything over 20kHz. Frequencies used for medical diagnostic ultrasound scans extend to 10 MHz and beyond. This dog repellent ultrasonic circuit will chase away angry dogs. It comprises of a 555 timer IC, a speaker/piezoelectric and a little ferrite transformer.
The main part of this circuit is a 555 timer IC. A 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package. You can use the 555 effectively without understanding the function of each pin in detail. Frequently, the 555 is used in astable mode to generate a continuous series of pulses, but you can also use the 555 to make a one-shot or monostable circuit. The 555 can source or sink 200 mA of output current, and is capable of driving wide range of output devices.
To use this circuit adjust R3 at resonance frequency of the piezo transducer for maximum amplitude of the repeller ultrasonic sound. At 30 KHz this can reach a value of 108 Vpp. Without the piezo the output voltage is around 200 Vpp.

Note: Ultrasonic frequency must be set with a dog nearby.

ReplyDeleteI am very pleased with the help CYBER CREDIT GURU rendered in restoring my credits. I am a disabled Veteran who over the past 2 years had to let my credit go due to health priorities that were not covered by VA & other insurance, my credit scores were 514 Experian, 515 Equifax, and 518 TransUnion. No public records, only 3 open Accts but several collection Accts with Zero Balances, few Weeks ago, I ran into some Credit blogs on the net which led me to CYBER CREDIT GURU the most talked about US based Russian hacker, who tremendously repaired and upgraded my credit score to 784, 789, and 802 within the 3 Bureaus in just a Week after I contacted him. If faced with similar challenge, connect with him via: C Y B E R C R E D I T G U R U (AT) G M A I L (DOT) C O M or Call / Text: +1(650) 239 7249 you too can be helped, I recommend him without hesitation.
