It’s a no-brainer that you can live off the grid with the help of DIY free energy sources such as wind and solar. And as our How to: Run Your Gadgets on 100% Green Energy proved, you do not have to ditch your electronic devices either. So if you happen to be living off the grid, or just want to build a fun, green way to expand the range of your internet, keep reading. This system is powered entirely using a battery which is charged from a solar panel and a wind turbine.
The eco-friendly rig also supports a VOIP phone in addition to the wifi repeater. To keep the supply stable, the electricity from the wind turbine and solar panel is checked remotely using a hall-effect sensor and microcontroller. The idea behind the project was to setup a low cost communications node in a location which does not have any infrastructure.
