Atmel Tiny85v draws about 4 uA at 3 V in deep sleep waiting for a watch dog timer. With a 4300 uF capacitor, it will run for many minutes (the voltage decreases by about 150 mV per minute). I'm hoping that a 4 Farad supercap will let it run all day.
The RC is still at 8 MHz; dividing by 256 to run at 31.25 KHz will probably help with power consumption as well.
I took this picture in 2011,when, just before the end of the three year extended warranty I had this TV went kaput. The technician replaced the power board, which probably solved the problem, then went on to replace the other two boards. He benefited with increased warranty payment from Samsung. i benefited with an extended life for the TV. Still works six years later.
And still works six more years later ... December 2023.
Day four. "Vegetable sheep" at Travers Saddle.
Funny thing about this place is that I felt quite comfortable. But you can tell by the surrounding vegetation that very little can actually live here. I would not have visited without sensible gear, shelter, and extra food and water, "just in case". And I would not have bothered at all if the weather report hadn't been good.
