Hi, first of all thanks Yuriy for a wonderful work!
I've made the dro based on arduino with Igaging Scales.
I would like to supply the scales with a battery but I've some problems.
A new scale draw about 15uA (50uA with original display on).
When I connect the scale to arduino, the current jumps to 600uA (or even more, sometimes 10-20mA).
The scale still works but, also with original display, it draws always 600uA or more.
I've tried with 5 scales...
No errors in the circuit (very simple, just 2 resistor for voltage divider for the clock line).
Anybody have got same problem? Any solution?
Thanks
