Bitalino has low cost ECG devices with Open Signals or Matlab software. Both OpenSignals software and Matlab does not run on the Pinephone.

Alternatively, Scott Hardens, PhD. Sound Card ECG device could be used. Scott s Sound card ECG is an excellent research grade device, he spend more than years in developing it.

I asked Scott:
Is it possible to integrate your free and open source custom software which is written in C#, which graphs the signal in real time and displays heart rate over time into Python?

Scott s answer:

Check the link in the description to my one opamp ECG circuit video. That project makes a similar graph using Python software and you may find that useful

And here my question to the Pinephone community. Is there a sound card input on the Pinephone which can be used by Python software?

Hi all.
I am using platform.io framework in vs code on PBP and having problem with communication to ESP32 dev kit from USB2 (right) port.
For example when I am running monitoring of ESP32 serial port I get errors:

My current experiences with Mobian, and compiling the kernel:

Brief overview:

- My main objective was to compile ZRAM module in to the kernel of Mobian.

What ended up happening I learned the following:

• uBoot
  
• Kernel
  
• (Mobian had a small partition so I had to modify uBoot to put a new kernel and module system on there)
  
  
• Serial Modules, and converting my raspberry pi connector to a  headphone UART option by cutting both a headphone cable, and a raspberry pi uart cable, and tying the wires together.
  
• Possible cheap option (by uARt, chip on amazon and cut a headphones  that the speakers are broken to make your own.
  12 bucks....max it looks like Canadian
  

• Kernels that images are gzipped  I couldn’t get to work correctly, I had to unzip it to use it within uboot
  
  
• Example working solution using boot.text compile boot.scr
  

• the bootargs environment
  
• ext4load for loading binary files into memory of uboot
  
• help
  
• help command
  
•  booti
  
•  bootm
  
•  boot
  

• Installed docker
  
• Download docker Debian image (latest version) using docker pull
  
• Install the build essentials for Debian
  
• Install the cross compilers needed
  
• Download the kernel using git
  

When I preordered a PineTab I intended to select DHL shipping, but DHL shipping did not get selected(my funble fingers). I live in the US does DHL make a big difference in delivery time and if it does can I change my shipping option?

are there any good docks for the PineTab or any plans for one?

I have just received my Pinebook Pro last week. Being a newbie, I am having some fun times setting up the Pinebook to fit my needs. I am mostly doing machine learning and mathematical optimization so this is an interesting experiment for me to try to achieve it using Pinebook. I am glad that many Python libraries such as numpy, scipy, scikit-learn, pandas are already included to be set up through pacman. But some others are missing.

My question is whether there is a way to set up a deep learning framework such as PyTorch in Pinebook. It is not for actual running purposes but mainly for development. I can find a couple of Keras libraries. There is also OpenCV. However, neither of these pieces are complete to work on a full framework. Any ideas?

Hello,

Having issues with the microphone on my PinePhone BH edition, I contacted Customer Service. After exchanging many emails Pine64 agreed to send me a replacement "daughter / side board", waiving the shipment fees if I pay $9.99 for the spare part. I was to create the order then email them the order number so they can refund the shipping fees (see their message below):

"Reviewed your communication with support team#2. To close the case ticket #XXXX  friendly, you purchase the item: PINEPHONE USB-C SIDE BOARD SKU: PPHONE-SIDEB $9.99, we waive the shipping cost.$11.99.

[...]

Let us know the order ID after you ordered the spare parts.

Have a nice day!

Regards,
Pine64 team"


After a few weeks (15/06), when I was nearly sure the microphone was faulty, I made the order, paid for the spare part plus the shipping fees, then emailed back the "Pine64 team" letting them know the order number so they can refund the shipping fees. I haven't heard back since. Today, after a week, I got an automated message from Pine Store (sales@pine64.org) informing me that my order was completed and shipped. The invoice shows the full amount, including P&P and the final value means that I will be paying custom duties and handling fees to the Post Office.

Not a word from Sales, or Customer Service, and I emailed them nearly every day.

I am a big fan of Open Source, PinePhone, and I really want so support the community but the so called "customer service" experience is hugely disappointing. I am afraid Pine64 is far from being a supplier who cares for their customer.

First, thank you to all involved in developing these solutions.  I could not design and build a Pinebook, and likely couldn't port NetBSD to it.

A few months ago, I dug out an old laptop to use as a portable VNC terminal to operate and administer the various computers (some "headless") that I have, which run NetBSD and Debian/Raspbian Linux. After finding out that the hard drive was quickly dying, I sought out another cheap, used laptop.  I also found out about the Pinebook which seemed more lucrative, since I wouldn't need to buy new obsolete batteries.  I then found out that it would be quicker to get a Pinebook Pro.  So I ordered one.  A few covid months went by but then one day I got a tracking number.  Two days later I had the Pinebook Pro in my hands, all the way from Hong Kong!  I can't get things that quickly from a hundred miles away.  What an amazing machine.  It seems very well engineered and built, especially considering the price.

I thought I would use the Pinebook Pro to download NetBSD.  I quickly discovered an error in my DHCP server.  The Debian that came with the Pinebook Pro would always clobber /etc/resolv.conf, even though I was using a static IP.  Oddly, I have two other machines running Debian Buster, which do not have this problem.  But I fixed the server, and was able to download a NetBSD image.  I could not boot from the SD card though.  When the SD card was inserted, the eMMC would not boot, but neither did the SD card. 

So I took the bottom off the Pinebook and switched off the eMMC, and switched it back on immediately after the SD card started to boot.  This turned out to be pretty straightforward and not as scary as I had read.  The trick is to open the lid 90°, and lay the Pinebook on its keyboard, with the display overhanging the edge of a table, for disassembly.  I carefully stood the Pinebook up on its side to operate it.  Of course, I made sure to remove the plastic standoffs first.  A speaker did fall out, but I pressed it back in.  When picking up the Pinebook to stand it on edge, I picked it up by the display half so as not to put any load on the hinges.

I tried for several days to use sysinst to install with small partitions.  There is something wrong with sysinst, going back to at least version 8, on every platform I've used it on.  The partitioning barely works and does some very bad things.  I never did get it to give me a working, bootable setup on the Pinebook Pro.  I only tried this because I like to have small partitions so that I can quickly make uncompressed images that easily fit on USB memory sticks.  So rather than try to partition and install manually, I put the installation image on the eMMC and let it grow itself.  When doing this, you can link /targetroot to / and still use sysinst to configure the system and install pkgsrc.

I initially did have some hiccups with the wifi.  I used FTP to retrieve the NetBSD image from a local server.  I had the "flood of checksum errors" problem.  But I rebooted and tried again, and did not have the issue again.  In fact, except for sysinst occasionally crashing, I'm finding NetBSD-current to be very stable.  Right now, it's compiling kde4, and has been doing this for over twelve hours.

Are these connected to an unused UART that can be enabled in devicetree? Or something else?

I have just found that my Android phgone is on its way out and I am thinking of really using the Pinephone instead, despite still being in development.

One feature I would like is the ability to backup my phone and SMS records for future reference. I tried to search for them, but have not found where they are stored.

As long as I can transfer the 2 files to my pc, I can find a way to convert them to CSV and then to LibreOffice Calc.

Can someone tell me where this info is stored, please?
