  • And not to mention the discharge efficiency curve. For LiPo batteries you will see a sort of “coasting” when the battery is at about 3.7v if your load is sufficiently small. But when it’s at 4.0v it will seem to drain quicker.

    I have a 10000mAh battery powering a device that uses 10uA every 30 minutes for about 10 seconds. On one charge it should last about 1 year maybe a little more. The first 2 months it seemed like it lost a lot more juice than was expected but since then it settled in and is now ahead of its estimate. Which means it will speed back up as it goes down below 3.7v.




  • Having not watched this yet, I’m going to guess that this failure state basically results in the processor simply incrementing its address pointer indefinitely which will inevitably just loop across the whole contents of the rom, along with current state ram data? Outputting audio might be a bug in this case, a hardware bug that is. Unless it was an esoteric way for the system designers to debug using oscilloscopes? Maybe it was meant to just dump ram contents but ended up hitting all rom addresses? Either way, I’m excited to watch this when I get some more time and just wanted to speculate based on the short description of the video I read.
