Sweet! Yea, I have several panels that have 2 of them for that reason. I have debated making a larger one since the code is open source. It would be great to have one that has more ports, and perhaps the ports combined into less cables.
I agree. I think a good way to solve this problem would be to move the ADC + circuitry to the induction clamp itself; then daisy chain the units together via some bus protocol. It's would allow customers to go from 0-X in terms of logged channels. As well as reduce the size of the sending unit considerably.
