Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Found this good product for monitoring USB charging phones, tablets etc
less than $3 on ebay and has internal 4 x 7 segment display that toggles every couple of seconds between current and voltage

I have one and I tapped across the current resistor (0.05 ohms) so that I could monitor the current with an external meter. I find that better when looking for pulses.

Eventually, I intend to make it into a current logger (with a micromite naturally).
