Re: Led + Video Probes

Thanks for the update.  It does look interesting but I guess I, as
others, would be nervous messing with the powerline!  I guess the
components are pretty simple but it would really have to put together
in a properly insulated / earthed unit.

I'll certainly watch your progress as I was quite interested in the
rest of the probe project too.

All the best

Richard

as to do so would require that i should have the device tested for
safety and it would not be financially viable.......So your
Electrician would have to put the sensing led /resistor/ diode
together as well as connecting it to the load side of the ld11....
