It came down to the wire but I did manage to finish a Week One PineNote video: https://makertube.net/w/cSDcWZVjFksZsxpPx5yo8j

@PINE64 has created an excellent device and the community around it is awesome, kind, and super helpful. There are rough edges for sure but it is totally usable out of the box and I'll go into application specific configuration in future posts/videos as long as people find this useful. Let me know what you'd like to see!

I'm seeing an uptick in video essays under the guise of "just asking questions" attempting to claim there is a conspiracy to destroy #OpenSource, #OpenHardware, #FOSS projects and culture by Far-Left Extremists, #Wokeism, and the #DEI agenda.

None of this is new. They only exploit a new sense of entitlement to more openly speak and act as they long have, emboldened by the spread of anti-democratic, authoritarian, irrational, emotion-driven, ethnocentric rhetoric and assaults on liberty by #Trump and the #TrumpRegime

Made an outline for the PineNote video. I'm going to put together a "good enough" video so it actually gets done and I can make more videos to cover different aspects later.

I'm surprised by the amount of interest but I'm so excited to see that. I want to do my part of the Community Edition contribution by sharing all the info I can. Software development isn't the only way to contribute to FOSS!

La #LibreIncu ya está funcionando en 8 proyectos productivos de #Córdoba!
El viernes se entregaron las incubadoras avícolas pensadas y desarrolladas a escala y necesidades de la #AgriculturaFamiliar 🐣
Y con la entrega hubo encuentro, capacitación y muchas manos poniendo en práctica lo aprendido.
Fue un día especial para todo el equipo de #AlterMundi
Fue la conclusión de un trabajo constante que venimos desarrollando hace más de un año junto a la Traslasierra Cto y con el apoyo de Agroecology Fund y Ministerio de Bioagroindustria

PineNote Fedi Q&A

Thanks for the interest. There were some overlapping questions, I'm reviewing by category. I don't have answers for every question but I'll do my best and some of it will have to come later out of necessity. I'll be adding a link to a full blog post here soon™.

Linux Experience

This is a first-class Linux device, full on Debian Trixie with a full Gnome desktop with Pine specific packages that are pinned so they're not overridden by generic packages. The on-screen keyboard has been the only source of frustration. The display runs at 200% and the keyboard isn't optimized for that.

Display Rendering Modes

There's a handy widget to change the current display rendering modes based on what you're doing.

  • Grayscale: 16 levels of gray for best quality, slowest refresh, good for graphics.
  • DU4: 4 levels of grey, great for reading (text is very crisp).
  • B&W + Dither: best for fast refresh needs, writing, terminal, etc. still easy to read but display will feel lower res.
    B&W and B&W invert: these exist but I haven't found them to be that useful for me yet.

Backlight

Wonderfully configurable from very dim to burn your retina. The white and the warm backlights can be controlled individually from the quick access, so you can create your own perfect color temperature. Genuinely delighted by this!

Applications

  • Terminal: Gnome Terminal, everything works great, touch typing hampered by on-screen keyboard but entirely good experience as a terminal with B&W + Dither mode.
  • Browser: Firefox, full install, works with plugins (only tried uBlock Origin).
  • Reader: KO Reader (more utilitarian) and Foliate (more UX polish) but both work great with epub and mobi, didn't try pdf much but it works. I will test annotation, marking, etc. later. It's a good eBook experience, I'm happy to say but as long you realize that it's not that small but definitely not heavy for its size and build quality.
  • Note-taking: Xournal++, works fine out of the box but can be improved with some community config. Haven't used the writing much, more on that in the future. Without config, totally usable but not a dream.
  • App Sources: Anything available in Debian Trixie and Flatpaks cab be enabled. I plan to test and use Flatpaks, will report back.
  • Sync: Syncthing built-in but I read people are also using NextCloud with it. Will test both in the future, might need a test NextCloud instance (if you want answers sooner).

Battery

Definitely not enough data to say. I've been poking and prodding the device most of the day and it has used about 30% of charge so that is very encouraging. Closing the folio case and opening it up again is almost instant response, which I love (was a big fear).
Speculation: The device must be doing some good battery management it seems since first launch of app after inactivity takes a bit to startup but is responsive after launch.

Peripherals

I have not connected Bluetooth devices yet, I plan to test it with Bluetooth mouse, keyboard, and headphones and report back in the utnext couple days.
Disclaimer based on very quick research: There's no USB-C dock functionality, the chip supports USB 3 PCIe,but the actual circuit out to USB-C connector is USB 2.0. There is no physical way for display mirroring (as in act as a external display) or multi-monitor support (as in extend/duplicate screen). But there are Gnome tools to achieve this, I'll play with them at some point.

@PINE64 I haven't tagged you on every single reply/post but I did want to make you aware in case I misrepresented anything, I'd be happy to correct any factual errors.

I have been really hoping the warm front light was decent. It is fantastic! That's about halfway up the brightness scale. The regular (white/blue) and warm front lights are separate sliders both in the quick access menu (white is totally off).

Garmin watch is still showing a bit more blue than white. I adjusted the color balance to correct for the camera and get it to a close as what I see in a pitch black room.

More updates later, send any questions you have. Quick (pine) note 🥁, the plastic back feels good but it's a fingerprint magnet but the folio cover is very nice.

The PineNote is here! I'm planning on making a hands on video to share my experience. Let me know if you have any questions you want me to try and answer. I don't plan to do technical tests but open to collaborating on it.

First impression, feels like a quality and sturdy device. Feels good in the hand, the texture is a kinda soft grippy plastic. Pen felt good, the writing friction seems ok, I don't want to make any software qualifications until I update the device but still happy with the out-of-box experience. The wake from sleep time is essentially instant.

@PINE64 great work on the PineNote, I'm very impressed with the hardware!

Edit: Link to blog post with thoughts after day one. Since I'm on a single user instance most people may not see the thread with info that hasn't been boosted, the post has all of it.

I finished assembling the TriacControl github.com/profdc9/TriacControl speed controller, which phase controls a universal motor based on an analog or PWM signal. It is to control the router spindle speed for a 2.5D CNC machine using the PWM output of a CNC controller. It could also be used with the PWM of a microcontroller, as the input can be configured for 3.3V-24V. The control signal and motor are opto-isolated. #diy #electronics #openhardware #hardware #opensourcehardware

I'm looking for an #NFC reader to use under #Fedora #Linux. Preferably without the need to manually install (proprietary) drivers.

I saw this recommendation:

reddit.com/r/nfctools/comments

So some options are:
ACR1252U
HID OMNIKEY 5022CL

Do you have any experience or recommendations? I prefer #openhardware and #opensource over proprietary.

What is the difference between #libnfc and #PCSC?

My use case is to log in at the #Belastingdienst (@belastingdienst) with #DigiD.

China plans to issue a policy to encourage the use of RISC-V chips nationwide for the first time. The policy is being drafted by eight government bodies, including the Cyberspace Administration of China and the Ministry of Industry and Information Technology. China has been embracing RISC-V in recent years due to its lower costs and geopolitical neutrality.

And a final constraint to spice things up a bit, I'd like to design a single project and make it "resizeable" in some way: the same set of PCBs should be usable for switching between 2, 3, 4, 5 or 6 amps (maybe more, we'll see) into a single cabinet.

Ideally one will just have to "cut" the PCBs to the appropriate size and/or populate the components needed for the chosen number of amplifiers.

Finally, this project will of course be 100% #OpenHardware, so stay tuned for more details 😉

The latest release of the #AirGradient firmware removed the code that phones home to the company servers even when you check the to to explicitly tell it not to do so. This is a big win for #privacy and #SelfHosting!

I plan on flashing this onto my device and testing it to verify nothing was missed. #tcpdump and #wireshark are my friends. 😄
