Build A Solar-Powered, Portable Wi-Fi Hotspot

If you'd like to pull down a strong Wi-Fi signal wherever you are, this simple but effective hack turns a router, a solar panel and a cigar box into a portable Wi-Fi hotspot that repeats any open Wi-Fi network it finds.

Essentially, the entire build is just a gutted Linksys router running DD-WRT, friction fit into a cigar box, with its power adaptor cord spliced to a small pack of AA batteries that is trickle-charged by the solar panel. As long as you have the raw parts and are comfortable soldering a few contact points, the build is no sweat.

On activation it continuously scans for open wireless networks, selects the one with the strongest signal, and repeats it locally for your Wi-Fi enabled devices to connect to. Watch the video above for a peek into the guts of the device or visit the link below for more information and a detailed build guide.
