If you do not need RT signal analysis, consider spitting data acquisition
and data analysis. Most loggers today have large memory or at least async
data communication
repetitive small spikes, but
rather more to protect your phidgets.

Thanks Arnaud.
The goal of the diodes is to protect the board - it cost more than the
resistors did. But yeah, I know.
Your point is especially true because those 1N5400s are odd - they list a
forward voltage around 1.2v, rather than 0.6v as you
.

I have wondered the same thing. I guess the Phidgets folks are somewhat in
this space - if you look at the prices of the modules here, for example:

green blocks, that's going to add up if you try to configure a system

Hi Jeff,
Good work! You could also consider this (
https://www.sparkfun.com/products/9028) for use with your A/D converter.
I'm using something like this with an IOIO board connected to an Android
device. This will give you both current and voltage.
Take care,
Jack
