Hi All,

I have been lurking and absorbing much from all who contribute... Thanks to All.

I have an ap that would require sending commands over the low voltage (existing) power lines.

I have seen it done on some commercial control systems, but couldn't get access to the guts to see how it was done.

Has anyone else seen this done?

Just to make this appropriate, the destination is a 16f628 and the comm is one way.

I have been toying with using the comparator across a shunt on the power line and a healthy cap to hold the micro on while the data comes through.

Thanks
Bo
