[chbot] Multimeter with USB logging

[Mark Beckett]

Not sure about the isolation capabilities.

For a few more dollars I had one of these.

The IR-USB lead is extra on the bottom end models, but comes with the 
top end models.
There is also a bluetooth module so you can get it directly to your phone.
