Ahoj,

I just had a "high power" soldering job with my Pinecil V2 (power supply: 65W USB C PD; soldering task: Thin steel surface) where I had the pinecil set to maximum temperature and constantliy heating the piece where I wanted to solder.

After some time (2 minutes or so) I heard some noises from inside the pinecil. It did sound a bit crippling, like boiling stuff escaping some enclosure, or so.

I immediately disconnected power supply.

Outside of the pinecil, I felt not anywhere hotness; after disassembling (which took some time where parts can cool down) neither.

Has anyone observed similar things? Is the Pinecil safe to use long time at high power (will safe-protect if too long)? Any thoughts on what I have observed?

I now did re-test without or with thermal load, and in both cases there are two types of noises:

* Some regular noise which sounds like coming from driving the power output FET (PWM noise),
* rarely, some irregular noise as described above.

The second one _may_ also be some noise related to regular operation, emitted by the small inductor on the PCB, but I cannot discern.

Does the regulation sometimes involve "very irregular" pulses through the power FET/ the inductor?

Regards!

I can add my Nextcloud Account in Prefs, and I will see my files in Dolphin or in Konqueror. But Phonebook will not sync any contacts. And in Merkuro Calendar and Merkuro Contacts I can set up DAV connectivity but it will throw an error.
Are there methods to make Nextcloud connectivity a little more useful, or is DAV mostly disfunctional these days?

every other day, Manjaro KDE plasma mobile's screen brightness gets stuck at a rather low level and the slider will flip back to it's before position. Is there any fix known?

Hello there,
I am just wondering if Pinebook Pro can handle 256GB emmc?
Has anyone try that?

I tried using the new 2.1 minimal image on the Star64, and I see that a lot of progress has been made, which is great.

However when I installed xserver-xorg and xorg-minimal-fonts and a bunch of other stuff to run the X server, I found that every single basic X program was unable to locate its fonts.

Xterm, rxvt, twm, everything failed to load any fonts. The only program that was able to find any fonts was Firefox (which was unusable for a different reason--slowness).

Is there a quick fix for this font issue? I'd like to go ahead and start using the X server.

UPDATE 1:
I've now also tried the Weston and Plasma variants.

1. Weston worked the best, insofar as X works and I could launch the terminal.
Weston has a bug where, if I log in as pine64, it logs me out and logs me in automatically as the user weston.
Also, there is very little by way of menus e.g. there is no mechanism to log the user out.

2. Plasma was (as expected) very slow and I think unsuitable for this type of computer. Plasma is better on gaming rigs. Plasma failed to launch the Terminal, so it was useless.

UPDATE 2:
I tried Minimal again and now, there are no packages related to X Windows available.

When voice call starts, only first 5 secs is with audio, then sound stops, while call is still active.

After this audio is in "Invalid state" as i can see in plasma mobile audio settings, when trying to play test sound.

This "Invalid state" can be fixed by switching audio profile of output from "hi-fi" to "phone call" and vice versa, as i noticed.

Any ideas how to fix? There is no errors in dmesg, but as for me it looks like some buffer issue, or another overflow.

pinephone with lte-m chip and volte.

i'm not seriously proposing anything based on lte-m at this point. putting new model is already a design problem.

because battery life is bad as something in pinephone (pro). could lte-m based chip alleviate power usage? of course volte (voice over lte) needs to work for this case. lte-m data speeds are somewhere around 1Mbit/s, meaning that there are slow. frequency band support might be reduced as well. do people have some knowledge on this issue?

what i know, cpu is the biggest waster of battery for pinephone and pro. modem chip is the second waster. so the reduction of power usage is probably not big.

Using Manjaro-ARM-plasma-mobile-pinephone-beta15-rc4.img. Booting stops and reports

"rcu: blocking rcu_node structures (internal RCU debug):"

Other OS'es boot successfully.

Any suggestions?

Hello

On the pinebook pro, where to buy a new TFT and how to replace it?

the display was white for several hours and now it looks damaged.

Thanks / kind regards

What if we could prototype and test Touchscreen Apps in the Web Browser, before running on a real device like PinePhone?

In this presentation we explain how we compiled the LVGL Graphics Library to WebAssembly with Zig Compiler. We created a Feature Phone App in the Zig Programming Language that runs in the Web Browser, calling the LVGL Library in WebAssembly.

The same app also runs on PinePhone with NuttX. We hope that this will someday enable NuttX Apps to be created and tested easily in the Web Browser.
