What's stopping you from daily driving the PPP? |

For those who have a PPP gathering dust in a drawer somewhere, what's stopping you from daily driving it? When I got mine earlier this year, I tried it out and made a list of things that stopped me from ditching my Android for it, which was:
- Need physical protection (cover). I looked around for other phone covers that could work for the PPP, but eventually got the PPP TPU cover. I wish it had the corner bumpers as well as extending over the front screen for better protection, so I'll keep looking for alternative covers.
- The biggest issue was battery life. Using Mobian, suspend worked, which helped, but I could barely browse the web for 1 hour before the battery meter dropped from 100% to less than 30%. YouTube went from 100% to 5% in under 30 mins! Luckily I discovered this is a software problem rather than hardware, hence my efforts to patch the kernel to fix the battery meter (see other threads), which is now working quite reasonably for me.
- A semi-working camera so I can document things or scan QR codes (not worried too much about quality). This is working now.
- Less of an issue: an offline GPS app for my camping/hiking trips. There are some options now (not all mobile optimized yet) like Organic Maps.
After the battery fix (still WIP), I've been able to daily drive the PPP for more than 2 weeks now without once reaching for my Android. I am surprised at how many things I use that works great:
- Calls and SMS
- Bluetooth audio playback
- Bluetooth keyboard for some terminal usage
- Software updates (and some great apps on Flathub like Foliate, Cozy, Papers, Telegram, Delta Chat)
- Web browsing with Firefox + uBlock Origin
- Media playback (videos, audiobooks, podcasts)
- Reading e-books
- Contacts/Calendar sync with my Nextcloud
- Alarms work even when the phone is suspended
- General reliability, i.e. phone doesn't randomly reboot or heat up in my pocket, etc.
There are still a few bugs I'm logging and hoping to either file an issue or fix myself, but nothing too serious. So the PPP might be discontinued, but I feel like it's just come alive for me! I ordered a USB-C dock so I can try out the convergence feature (there's a YouTube video of a guy doing web dev on this PPP like this and it has me excited!)
So if you've got a PPP and you aren't using it, what's stopping you?

| Multiple NEMA 17 stepper motors with the Teensy 4.0 |
|
Posted by: Harry - 08-22-2025, 12:24 AM - Forum: General

Good afternoon everyone,
I'm working on a project that requires six NEMA 17 stepper motors. I can use the standard A4988 or the more powerful DRV8825 driver, but both are 5V devices, while the Teensy 4.0 is a 3.3V device.
Can these drivers be used directly with the Teensy without damaging it?
Do they require a logic level converter?
Are there other compatible 3.3V stepper drivers?

| Giving away a Pinebook Pro for free (with a broken hinge) |

Hey!
The hinge on my Pinebook Pro has broken and I don't feel like fixing it. And since I'd hate to throw this thing away for just that reason, I'm willing to give it away for free.
I'm shipping from Germany near Hamburg, just send me a message here or on IRC (same username as here) if you're interested. You would however have to pay for shipment, after successfully receiving the Pinebook Pro.
Fixing that hinge apparenly involves gluing it, for more info post a message in the #pinebook channel on the Pine64 IRC, it appears to be pretty repairable using the correct type of glue.
Tell me what you're going to use the PBP for!
This is how I'm going to rank this:
1. Developers - reputable developers in the Pinebook Pro community who need some extra hardware to play with and don't necessarily need a working hinge.
2. Newbies - people interested in buying a Pinebook Pro and in fixing that hinge.
3. Enthusiasts - existing Pinebook Pro users interested in spare parts and willing to distribute remaining spare parts further.
If you're a developer, send me a link of some sort to a list of previous contributions.

| fixing the ppkb mainboard rather than replacing... |

Dear all,
I was hoping to brain storm the community on how to fix the pinephone keyboard mainboard rather than just replacing it when the charging chip overheats and gets fried as it seems to do every 4-9 months for me.
I must have at least 6-7 mainboards in my possession now (only one of which is working sadly).
I have never soldered before, but would be willing to learn, particularly if the replacement charging chip could be bought for very cheap and it just needed desoldering the old one and soldering on the new one. This would be a good reason to start my soldering journey...
Glad for anyone's tips on this.
BW

Pinephone pro stuck while booting |

So i have a pinephone pro and i have tried every thing provided here https://forum.pine64.org/showthread.php?tid=18216 and gotten assistanve on discord which still did not help. Ive charged for approximately 10 hours on Maskrom, tried using a sd card, flashed directly to EMMC, attempted to reinstall Towboot, Used a gui tool and dd, and still it will not work. Whenever i turn it on with a working os installed it will flash red then yellow then stay stuck, the screen wont even show anything. If i try without an os on the phone it reboots as the it knows there no os installed. Sometimes too when i turn it on it will stay red and just vibrate as soon as it is turned on. It will not even boot to an SD card if i use either the RE button or the volume down button. I can however boot into mass storage mode by holding volume up and connect it to the computer, im not sure how much this can help but if anyone can help pls do.

| Compatible U.S. carriers with web voicemail access? |
|

Anyone know of U.S. carriers compatible with the Pinephone that have access to voicemail via a computer using a web browser? So far the only one I've come up with is T-Mobile which is a bit pricey. (T-Mobile does have inexpensive pay-as-you go plans but it looks like you can't bring over your existing phone number. I've had my cell phone number since 1992 and don't really want to change it.)
The reason: Just a few days ago my carrier AT&T discontinued their voicemail notification feature which I have used for decades - it notified an external device (pager) when a new voicemail arrived. This was a legacy feature from the early 1990s that probably nobody provides any more. However I would still like a way to check for voicemail that does not involve turning on and using the phone. (I leave the phone off most of the time for privacy as I have no wish to be tracked 24/7). Although possible to retrieve voicemail from a land line that is an increasingly rare thing to find when not at home.

| Long dialpad keypress to retrieve voicemail |
|
Posted by: Zebulon Walton - 08-15-2025, 01:35 PM - Forum: Mobian on PinePhone
- Replies (3)

AT&T has made some unwelcome (at least to me) changes to its basic voicemail service. Now the simplest way to check voicemail from one's phone is to hold down the "1" key on the dialpad to issue a long tone. However this does not work on the Pinephone, at least not running Mobian Bookworm+Phosh.
It is not clear whether this long tone triggers something proprietary in a phone provided by AT&T or whether just sending the tone out over the phone network is sufficient. (It does work if I put my SIM back in the flip phone AT&T sent me when 3G service was discontinued in the U.S. but I did that just for test purposes, I don't want to actually use that stupid Google-infested thing.)
Anyone know if this can be made to work on the Pinephone? I can still retrieve voicemail by dialing my own number so am not dead in the water but it's necessary to enter a security code each time which is a bit of a PITA.)

Heyy
New to this but
How does one find a manufacturer for something like a mind link or else something to be used in conjunction with a prosthetic limb or anything else like that
Nerve related or cranial but not surgically implanted
Topical?
Also love pine64
I'm here. Would like to build new things and learn to better networking systems .
