| arno11 | KREYREN: most of them are in the wiki: https://leste.maemo.org/Nokia_N900 | 00:29 |
|---|---|---|
| KREYREN | and those which ain't? :p | 00:30 |
| KREYREN | i am the kind of guy who would spent weeks of work to get 0.1% improvement | 00:30 |
| arno11 | ah cool same as me lol | 00:30 |
| KREYREN | :D | 00:30 |
| KREYREN | it's passion art and a curse! | 00:31 |
| arno11 | definitely. so to resume, you mainly need to block trackers from $HOME, use 500MHz as min freq, deactivate apt-worker and the important stuff missing is a custom transitions.ini file | 00:36 |
| arno11 | let me find a link | 00:36 |
| arno11 | https://github.com/Arno1103/leste-config/commit/ae3f5db | 00:40 |
| Wizzup | ah yeah let's see if we can get these things in tomorrow, the swap as well, for 6.6 | 00:40 |
| Wizzup | since I think we can put 6.6 in devel this weekend | 00:40 |
| arno11 | ah yes could be really cool | 00:41 |
| Wizzup | my n900 doesn't always boot well still, but this could be home wrt trackers or not havnig 500 as min freq | 00:45 |
| arno11 | KREYREN: other tips: in the wiki there is the old overclock method using uImage: this way you can tweak dts and change voltage and freqs | 00:45 |
| arno11 | Wizzup: ah ok | 00:46 |
| Wizzup | but I also have *both* swaps atm since when I removed the emmc one I didn't get it to boot well at all | 00:47 |
| Wizzup | not sure what's up :D | 00:47 |
| arno11 | emmc is definitely buggy now but boot issue seems an 'unknown' stuff (mine doesn't boot well also) | 00:50 |
| arno11 | i tried to remove everything i can and still have boot troubles | 00:51 |
| KREYREN | why is 500 as min frequency important? won't that hurt the battery life? | 01:12 |
| KREYREN | Wizzup, elaorate on the fails to boot part? Mine sometimes boots without backlight on, but that seems to be due to getting it to boot via plugging in the USB cable instead of doing the power button that seems to be very important to charge capacitors to get proper display initialization | 01:13 |
| arno11 | KREYREN: absolutely no impact on battery life | 01:14 |
| KREYREN | arno11, that sounds like it's breaking the laws of physics O.o | 01:14 |
| arno11 | not really, there is a bias | 01:14 |
| KREYREN | What's the benefit of that? faster overall responsiveness and avoiding the annoying times when the apps loading and maemo seems frozen? | 01:15 |
| arno11 | exactly | 01:15 |
| arno11 | and avoid power draw during unresponsive times | 01:16 |
| arno11 | but other things make it unresponsive: trackers, emmc swap (with kernel 6.6), blur effect in transitions | 01:23 |
| KREYREN | i see | 01:24 |
| arno11 | and slow sd cards ofc | 01:28 |
| KREYREN | yea | 01:29 |
| arno11 | tbh now it is quite easy to improve/solve. the difficult stuff with n900 is power management | 01:30 |
| arno11 | long weeks needed for few mA lol | 01:30 |
| dsc_ | arno11: ok, thanks | 01:31 |
| arno11 | no probs | 01:32 |
| KREYREN | arno11, yea i imagine that NixOS would make things a lot easier for like the deep optimization, but getting hildon packaged will take some time | 01:34 |
| KREYREN | Do you get a good audio for SIP calls btw? mine is currently very unusable i hear like every 4th word and bad at that | 01:35 |
| KREYREN | i noticed that there is a command to change the pulseaudio priority though | 01:35 |
| arno11 | yes it helps most of the time | 01:36 |
| arno11 | and yes i get good audio with sip | 01:36 |
| KREYREN | Do you get more than 2G network? | 01:36 |
| arno11 | yep 3.5g | 01:37 |
| KREYREN | says 2G for me at all times in country which has 3G everywhere | 01:37 |
| KREYREN | calls are much better with that chrt command, but still way too quiet and it seems to be loosing signal a lot | 01:39 |
| arno11 | weird | 01:39 |
| KREYREN | oh it suggests Twinkle i am using the sphone thing | 01:40 |
| arno11 | ??? so you mean you got sound both ways with sphone/sip ? | 01:40 |
| KREYREN | yes | 01:40 |
| arno11 | Wizzup: ^^^ | 01:41 |
| arno11 | great | 01:41 |
| KREYREN | is that not suppose to happen? :D | 01:41 |
| arno11 | yep :D | 01:41 |
| KREYREN | lol | 01:41 |
| KREYREN | was using that for phone calls for last 2 days kinda had to employ talking as if it was a very unreliable radio but it got the message across.. with the chrt it seems much better though | 01:42 |
| KREYREN | i just sometimes get the phone vibrating in my pocket and wont stop unless i reboot it though | 01:43 |
| KREYREN | without like anything on the display | 01:43 |
| arno11 | ok that's an old bug being back | 01:44 |
| arno11 | and when you say phone calls, you mean sip calls through sphone, right ? | 01:45 |
| KREYREN | yes | 01:46 |
| arno11 | ok let's see what Wizzup and uvos think about that. | 01:47 |
| KREYREN | also with those tweaks the phone feels like a modern flagship in terms of responsiveness :D | 01:48 |
| arno11 | yes :D | 01:49 |
| arno11 | did you try boost mode btw ? | 01:49 |
| KREYREN | nope how to enable it? though i kinda prefer the battery life | 01:50 |
| arno11 | oh no worries, almost no impact (well...just a bit) | 01:50 |
| arno11 | see overclock in the wiki | 01:51 |
| arno11 | just 2 command lines to use boost mode | 01:51 |
| KREYREN | will do though i should probably wait for the new battery as the one i am using is kinda really old and i fear that it won't be able to pull a lot of watts out of it | 01:52 |
| arno11 | yeah ok | 01:52 |
| KREYREN | bought paxona branded one but it didn't arrive yet | 01:52 |
| arno11 | ok | 01:53 |
| arno11 | zzz time here | 01:54 |
| arno11 | gn | 01:54 |
| KREYREN | woah that boost is fast :D | 01:54 |
| KREYREN | good night thanks for helps <3 | 01:54 |
| KREYREN | now i just need a functional web browser and i am happy :D | 01:54 |
| arno11 | you're welcome | 01:55 |
| Wizzup | Interesting to hear that KREYREN gets audio in sip calls in voicecall manager | 11:15 |
| Wizzup | that would be super welcome news, then we just need to figure out how he got it to work and what we need to change :) | 13:09 |
| arno11 | Wizzup: i can confirm it works on my device as well. but only in one way (but with a very bad connection btw) | 14:01 |
| arno11 | i'll try again when back to home | 14:01 |
| Wizzup | ok, it might be time to rnu gabble with additional debug and compare our config/settings | 14:02 |
| arno11 | ok | 14:08 |
| Wizzup | back in a few hours :) | 14:08 |
| arno11 | me too | 14:08 |
| arno11 | ttyl | 14:08 |
| KREYREN | So i turned the boost mode on and it actually killed the battery xD Won't charge anymore | 15:56 |
| KREYREN | good thing the replacement that should have much better health arrived today | 15:56 |
| sicelo | that shouldn't happen | 16:03 |
| sicelo | the won't charge anymore part, that is | 16:03 |
| KREYREN | sicelo, the battery is very old it was barelly hanging by, it seems that the increase of 0.2A is too much for it | 16:08 |
| sicelo | i think that shouldn't prevent charging | 16:09 |
| sicelo | anyway, you have a battery on the way ... | 16:09 |
| KREYREN | it's effectively charging at 1.4W atm and afaik the BMS cut out is 1.5W bcs it has too much of internal resistance now? | 16:12 |
| KREYREN | and it was at 1.58W charging before | 16:13 |
| KREYREN | took like 14h to get full charge | 16:13 |
| KREYREN | also heats up a lot | 16:14 |
| sicelo | ok | 16:14 |
| KREYREN | Did anyone tried to make a DIY battery for N900 before btw? | 16:17 |
| KREYREN | was thinking about reverse-engineering the BMS and putting a lipo on it | 16:17 |
| sicelo | i think you asked in #maemo the other day, or was it someone else? yes people have run the N900 on 18650 in 2S config for example | 16:19 |
| KREYREN | wasn't me | 16:19 |
| KREYREN | oh there is a whole forum post about it on maemo website :D | 16:19 |
| KREYREN | cool | 16:19 |
| KREYREN | The diagram is kinda sketch | 16:20 |
| KREYREN | hmm it has 3 pins right do you need anything special sent on the 3rd pin for the data> | 16:20 |
| sicelo | iirc it's meant to be a thermistor, whose resistance feeds an ADC in the phone. it's used to estimate the battery capacitance | 16:22 |
| KREYREN | i see | 16:23 |
| sicelo | there should be information about the average resistance you can put it (so no necessarily a thermistor) | 16:23 |
| KREYREN | so basically it tells the N900 when to stop charging when the battery is too hot right | 16:24 |
| sicelo | not really @ getting hot | 16:25 |
| sicelo | unfortunately n900 charging & fuel gauge circuitry is a bit of a hack. tldr; the chip that does temp sensing for the battery is actually located in the phone, not in the battery | 16:26 |
| KREYREN | i see | 16:27 |
| arno11 | KREYREN: 14h to get full charge ?...wow something went really wrong lol | 17:03 |
| arno11 | usually boost mode has almost no real impact on a good battery (no excessive heat or high power usage) | 17:05 |
| arno11 | at least on my device | 17:05 |
| arno11 | btw 600 and 805MHz use the same voltage actually | 17:09 |
| KREYREN | arno11, it seems to have increased the power draw by 0.2 A which apparently was enough to finish it :D | 17:15 |
| arno11 | 200mA seems a lot | 17:17 |
| arno11 | 0.2A @idle ? or doing something specific ? | 17:18 |
| KREYREN | arno11, how's the power consumption on your end? the pcb that i have in it atm was very hugged up when i got it so it's possible that somethign does too much resistance | 17:18 |
| arno11 | pretty sure something is really wrong | 17:18 |
| arno11 | most of the time with boost mode, it stays @500 600MHz as usual | 17:19 |
| arno11 | and i've never seen such a power draw with higher freqs | 17:20 |
| KREYREN | arno11, would it be too much trouble for you to take the PCB out of the device and report to me the resistance on the test pads using a consistent ground? Would help me a lot to fix the other N900 which basically has a black spots over the PCB and lithography sparks on the antenna on the case | 17:20 |
| KREYREN | ideally the ground on the hackerbus | 17:21 |
| * KREYREN 's both N900 were saved from e-recycling service and he basically had to rework the whole PCB to get the device to work | 17:22 | |
| arno11 | sorry too much trouble for me: already have damaging parts on it :( | 17:22 |
| arno11 | ah ok i see | 17:23 |
| KREYREN | yea i ideally need this from a device that is in mint condition :D | 17:23 |
| KREYREN | i will be open-sourcing the PCB so that should fix these issues after though | 17:23 |
| arno11 | really ? | 17:25 |
| KREYREN | yep :p | 17:25 |
| KREYREN | i have plans to put a riscv SoC on it as well, but first i need to figure out the SOM solution https://git.dotya.ml/kreyren/OSHW-System-On-Module | 17:26 |
| KREYREN | (not up to date there is more work that i am putting together into a sensible standard) | 17:27 |
| arno11 | ok, really cool btw | 17:28 |
| KREYREN | ^^ | 17:29 |
| KREYREN | there is still like 2 weeks of work so hopefully in a month the SOM will be handled and then making the PCB is like 8 days of work | 17:30 |
| KREYREN | bcs just making exact copy would be too expensive to fabricate | 17:31 |
| arno11 | ok, ofc | 17:32 |
| KREYREN | the SOM fixes that by utilizing that lot of PCB fabricators will do up to 8 layer pcbs for 2 EUR and you get 5 of them, but they have to be below 50mm2 so putting that on a 2 layer board with spread out pins to be able to route it | 17:33 |
| sicelo | you're the one that asked for Neo900 files (gerber)? I've been asking myself where I remember your nick from | 17:39 |
| arno11 | really interesting stuff | 17:40 |
| KREYREN | sicelo, ye | 17:41 |
| KREYREN | sicelo, h | 17:42 |
| KREYREN | sicelo, guy from the hackerspace that cooperated on the neo900 project was at our hackerspace yesterday even :D | 17:42 |
| Wizzup | KREYREN: which hackerspace? | 18:59 |
| KREYREN | Wizzup, Ours is Base48 and the german one is ChaosZone | 18:59 |
| Wizzup | Ah in brno | 19:04 |
| KREYREN | Ye | 19:05 |
| Wizzup | btw, I think the PA change for shm also fixed ringtone for me | 23:27 |
| arno11 | it works again for me as well | 23:30 |
| Wizzup | maybe we should try the 4? (or 8?) that FMG suggested | 23:32 |
| Wizzup | I think I am still on 32 or 16 | 23:32 |
| arno11 | i tried 4 | 23:33 |
| Wizzup | works well? | 23:33 |
| arno11 | performances with emulators decreased | 23:33 |
| arno11 | otherwise, no change | 23:34 |
| Wizzup | interesting | 23:34 |
| arno11 | yep | 23:34 |
| arno11 | example: | 23:34 |
| Wizzup | I will set 8 for now | 23:34 |
| arno11 | with 64, picodrive can't run @60 fps + audio 44100 and need a bit of frameskip | 23:35 |
| arno11 | with 32, works fine | 23:35 |
| arno11 | with 4, same as 64 | 23:36 |
| Wizzup | strange | 23:37 |
| arno11 | yep | 23:37 |
| arno11 | maybe that's just a weird stuff with pico | 23:37 |
