| Video Discription | [ENABLE CAPTIONS!] In this video I am showing how to build ultra cheap ultrasound Dictaphone / Microphone jammer to protect your privacy against unauthorized recording or eavesdropping during business meetings etc... Whole device costs less than 30 USD and is very simple. Please notice that commercial solutions giving the same jamming results cost 10-50 times higher and I am giving you this solution for free. So plz reward me with a LIKE at least :-) The ultrasound audio jammer / audio recording blocker - is composed of : - Arduino DIGISPARK ATTINY85 based unit or Arduino Pro / Nano / Mini etc - both versions of solution available (6 USD), - Audio power amplification module PAM8403 (1 USD), - Signal Generator board AD9833 ( 3 USD ) - set of 10-20 ultrasound transducers for 25kHz ( 10 units cost 10 USD). If constructed properly the jamming range is up to 10 meters (conference rooms) in closed areas for most low end chineese surveillance devices. PAM8403 module gives 6 Watt of audio output power on 25kHz but it can be replaced with any other like PAM8610 for 2x10Watt output. No additional programmers are needed ( ARDUINO DIGISPARK is programmed over USB from Arduino framework on Windows/Linux/Mac) Whole project data can be found here : https://github.com/mcore1976/antispy-jammer DIGISPARK version https://raw.githubusercontent.com/mcore1976/antispy-jammer/main/arduino-mic-supresor-ultrasonic-v2.png https://raw.githubusercontent.com/mcore1976/antispy-jammer/main/mic-jammer-ad9833-digispark.ino ARDUINO Nano/Mini/Pro version https://raw.githubusercontent.com/mcore1976/antispy-jammer/main/arduino-mic-supresor-ultrasonic-v2-pro-mini.png https://raw.githubusercontent.com/mcore1976/antispy-jammer/main/mic-jammer-ad9833.ino The ARDUINO with AD8933 generates pulse wave with 25kHZ center frequency which is randomly changed within +/- 2kHz area to achieve white noise. This white noise leaks to hearable frequencies 100-5000Hz and overloads hidden microphones. You may hear this noise in my video.. Please notice that there are some hi-fi microphones that may not be jammed with this device - especially these with several microphones and software echo cancellation. There is never 100% effectiveness but this device may suppress huge range of recording devices (voice assistants, dictaphones, wiretaps, audio recorders, cell phones, tablets, laptops, hidden cameras, gsm bugs, laser microphones, direction microphones etc.) In the video I am showing how the device works for two different phones in the video - cheap and expensive one - you may compare its efficiency. If you are businessman or politician conducting some negotiations this kind of device is must have for you to protect your privacy by protecting your private conversation and secure your business.
