Thanks for some of the links in this thread. I'll try a few of them out. Do you guys know if they're a constant drain on the battery? Especially if you set the refresh interval to every second, wouldn't this drain battery much quicker?
On my recycled android, i have a custom rom ... so i have decrease to 206MHz (instead of 1200MHz) and check the "always ON when USB connected" (developper section).
The picture is static on the widget, it refresh every minutes (i use the 1 hour display option for this refresh).
