Special kind of power analysis: wall power


I wanted to share this little hack with you. I am trying to use the CW to find a broken cable in my house.

it is called wall whisperer youtu.be/wIX1ZVHkrfk


Interesting, if the CW is the only MCU you have.

You can achieve the same thing with a $3 MCU board like the STM32F103C8 from eBay, and the Arduino IDE, as that can generate a 36Mhz or 18MHz signal etc
