In general the idea behind lowtechmagazine.com is to understand technologies and techniques of the past and combine them with the knowledge of today. Not in order to be able to 'do more with the same', but rather 'to do the same with less'.
In this particular case it means that all the optimizations and increases in efficiency do not go towards making a website which is faster at delivering even more megabytes. Rather it is a website which uses all the advances in technological efficiency, combined with specific hardware and software choices, to radically and drastically cut resource usage. At the same time for us a sustainable web site means ensuring support for older hardware, slower networks and improving the portability and archiveablilty of the blog's content.

This meant making a website and server which could be hosted from the off-grid solar system used in the lowtechmagazine.com's home-office in Barcelona.

### Server
The server itself is an [Olimex Olinuxino A20 Lime 2](https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2/) single board computer.
We chose it because of the quality of the (open source) hardware[^olimex], the low power consumption and useful extra compnents such as the charging circuit based on the [AXP209 power managment chip](http://dl.linux-sunxi.org/AXP/AXP209_Datasheet_v1.0en.pdf).

This chip makes it possible to query power statistics such as current voltage and amperage both from the DC-barrel jack connection and the battery. The maintainers of [Armbian](https://www.armbian.com/olimex-lime-2/) exposed these statistics via `sysfs` bindings in their OS.
