With a Wi-Fi hotspot, you can remain connected to the cloud from anywhere. Even then, a Wi-Fi router needs electricity to operate. To cut this umbilical cord, you can power it with the help of the sun or the wind just like this portable, solar powered Wi-Fi repeater.
A solar panel powers a Linksys WRT54G v8 router with 7.5 volts at 500 milliamps in direct sunlight. For sunless times, you have a backup of 5 AA batteries that get charged up thanks to the solar panel. The solar-powered repeater is packed neatly into a cigar box for easy portability.
What’s even neater is that the self built Wi-Fi repeater has a custom firmware called DD-WRT that scans and connects to the strongest signal automatically and then repeats it. You just need to switch on your laptop and connect to the web. See how it works and download the instructions as a PDF.
