Hi
the one that was a tech electronics, the way that it was show, and fully exlained, they saw the meters readings for them selves and another did the calculations, so there was no hidden smoke and mirrors. well yes they were a little short on words.
When you can see the cam and with out a shadow of doubt that the power can only be on for that short period and off for the rest, it was a good idea to show with out and funny electronics.
