For reasons I won't bore you with, I'm interested in building a cheap,
simple data logger to monitor mains voltage, ideally two channels (live
to earth and neutral to earth). In the dim and distant past I have
designed and built such things more or less from scratch, but surely
someone has already done this.
I havn't used either Arduino or Pi before, but I assume one or other
would be the obvious starting point.
However ATM google isn't giving me a strong lead. Thoughts?
A quick google came up with:

Thanks, that second one looks like a good basis.
Won't the capacitor smooth out any transients you might want to observe?
