[IDEA] Power Draw Widget

---

Could someone build a widget to loop the "cat sys/class/power_supply/battery/current_now" script every 30 seconds or so and display the results in the widget? This could give you an accurate idea of how much power your phone is using regularly.

UPDATE

rm9 has made a widget off this idea, he has posted it to the market.

Gotta bump this while noting I'd pay for such a widget.

+1 for payage

EDIT: Or, even better, a graphical history widget like SeePU++

I have never done programming before, but this might be enough for me to look into and see if I can learn enough to put something together.

What are the units for current_now ?

Microamps, Probably would be best for the widget to display in Milliamps.

It displays total current to/from the battery, - means it is discharging the battery, + means it is charging the battery, so if you have a - while charging it means you are pulling more power then your power supply can provide.
