Samimy is at it again. And this time, his ingenuity has tackled a clever way to take something old and broken and restore it to something new and useful. What are we talking about? Modding a broken hard drive and some busted cell phones into a useful rechargeable USB / solar-powered light, which also acts as a portable mobile charger.

Parts Needed:

* Broken HDD (1)

* Broken cell phones (3)

* 3V DC voltage regulator

* Solar boards (2) 10cm x 6cm, 1.5V each

* LEDs (10) each 3.4V, 30 mA
