RECESSIM explains how to safely power a smart meter from 12V instead of 240V by injecting a sine wave to enable JTAG debugging.
*BECOME A PATREON!* patreon.com/RECESSIM In this episode I figure out how to power the smart meter from 12V instead of 240V so we can safely connect a JTAG port to the computer over USB. There is danger in blowing up the smart meter, JTAG adaptor or computer if we power the meter from 240V and plug it all together. I had to inject a small sine wave into the meter to make it think it's connect to a 240V AC power source.
