Okay!  So apparently there is some interest in power line communication
for GSoC.  But, what we would want to do is already have a safe way of
connecting the USRP in to the wall socket for the student(s), and for
the future of GNU Radio and USRP power line communications development.

So, as a goal of this thread I'd like to get some feedback on how we can
make this possible.  Ideally, something off-the-shelf would be great,
providing the highest amount of safety for those experimenting with it.

Here's a very simple approach:


There was a bunch of discussion about this on the time-nuts mailing list, and some folks suggested changes for increased safety (including putting two resistors in series so that if one fails short -- which is a very unusual occurrence -- there's an extra layer of protection. But in general, with large value resistors the current is limited to a very safe level -- and it's current that kills, not voltage.
