CatButts | tempting to install, but at same time, waiting for it to mature more | 00:01 |
sixwheeledbeast | indeed | 00:15 |
sicelo | CatButts: or join the effort and help it to mature faster | 02:00 |
Wizzup | :-) | 02:03 |
Maxdamantus | Hmm .. a female type-A to female type-A USB OTG contraption would be crossover, right? | 04:59 |
Maxdamantus | actually, maybe it's straight-through. | 05:11 |
Maxdamantus | Seems to be straight-through. | 06:09 |
Maxdamantus | Hm, wonder if the bq27200 chip doesn't take into account power consumption power drawn from USB, or if my keyboard was just using relatively large amounts of current when my N900 decided to shut down. | 10:07 |
Maxdamantus | (was on VDQ=1 since it had become uncalibrated, and now it only has an LMD of 1247 mAh) | 10:08 |
KotCzarny | or higher current draw results in earlier vdq trigger | 10:12 |
KotCzarny | ie. battery gets old | 10:13 |
Maxdamantus | You mean EDV1 trigger? | 10:15 |
Maxdamantus | and you mean it thinks the battery gets old? | 10:15 |
Maxdamantus | because a higher current draw leads to a lower voltage even though the battery is still in good condition. | 10:15 |
Maxdamantus | (and the EDV1 trigger is only based on voltage, not something to do with likely battery condition) | 10:16 |
KotCzarny | yup | 10:18 |
KotCzarny | so the curve is lower | 10:18 |
KotCzarny | and it gets 'empty' earlier | 10:19 |
KotCzarny | and the older battery gets, the curve is even more lower | 10:19 |
KotCzarny | and usual 20-100mA of usb keyboard is a lot for a device that idles around 10mA | 10:20 |
Maxdamantus | Mm, I had the keyboard plugged in but unused for around 3 hours or so, but happened to be using it when it powered off. | 10:21 |
Maxdamantus | was also running fluidsynth and outputting to alsa, so maybe that also used some power. | 10:22 |
Maxdamantus | well, was outputting to pulseaudio before that, which would probably have used a decent amount. | 10:22 |
