Do you need such a single payer?
The purpose of the post is to review an alternative direction for the development of mobile devices under free axes (And it is not a PostmarketOS review, but in general it would not hurt for Habr)
At the moment, in the world of user mobile devices, the paradigm reigns – mono devices. Not the last contribution to the cost of which they owe to the display.
Life without display
What happens if the display fails?
Replacement ? Device replacement?
Is it possible to use a device without a screen?
WiFi left? – Quite.
Is the processor working? – Definitely.
Are the RAM and flash drive working? – Yes!
A possible solution would be to install Postmarket OS
There are nuances – a list of supported devices is on the official website.
Installation is not difficult. There are also precompiled images.
Concept
In my humble opinion, the way of repeating a mono device, for the giants, of course, is the place to be. UbPorts and various graphical shells for PMOS are quite usable.
But, what if you divide the wearable device into 2 parts?
Part is “Mobile Server” without screen
Part is a lower performance device with a screen through which work is done on a mobile server.
Or any smartphone (or PC or Laptop)
This makes it possible to change the viewing device, without replacing the main one – which is devoid of such a fragile part as the display.
Already today, a cloud IDE in docker can be installed on a device with PMOS
and the backpack will have its own development server or various office solutions.
And in the current conditions, careful attention to the available capacities is more than justified.
The working name of such an OS, I decided to choose as – Polu OS.
Not so simple
Yes, there are questions
Although the device looks like a mobile device, it is no longer so)
in terms of energy efficiency, it is supposed to be enough for 4-5 hours
Alpine Linux is not as optimized as for example Android in terms of consumption.
But, the paths are open and the possibilities of optimization are not limited.
And yes, such a mobile server is a geeky project, but it can be a pretty good solution.
For example, there are all the prerequisites for what would “give a call” could be by saying the password from the access point on the server and the domain.
On which you can dial a number and make a voice call using the web interface.
(Well, or be hacked))
What about iron?
7z benchmark ( 7z b )
Asus A53C on i7 – 13566
—> Samsung A5 – 3157 <---
Orange Pi+ 2 – 2144
Asus EEEPC901-1245
(If anyone has Orange \ Rasberry share the results of this benchmark)
Someone will rightly ask, what about GPIO?
Up to this point, NodeMCU on ESP8266 was enough for me)
But, seriously, a full-fledged single-payer is already a different category.
What does this server look like live?
At the end
I would like to express my deep gratitude to everyone who sawed and sawed PMOS,
thanks to you, I have the opportunity to use such a budget single-payer.
