First prototype of the solar powered server that runs the new website. The solar charge controller (on the right) is powering the server (on the left) through a USB-cable.

Battery meter

The background of this website is a battery meter, designed to always display the relationship of the energy powering the website and the visitor traffic consuming it. At the moment, we are running the website on a 24 Wh Li-Po battery (3.7 V, 6.6 A). That’s enough energy to run the site for 12 to 24 hours, depending on visitor traffic. We will add more energy storage as the days get shorter.
