How are most people connecting the ground wire to the magnetic pin? Solder? Beside the alligator clip, there were no other connectors provided.
If you are asking about DIY touch plates: I made mine with aluminium business card 
I drilled hole in one of the corners and crimped connector to the cable. Then just used small screw/nut to attach.
Then on the other end I used the same connector to attach cable to round magnet, with hole like this:
It works pretty good
I purchased the V1 kit and think I’ve figured out a decent way to connect the magnet to the wire. I’ll test and find out.
