I saw this Rotary Phone in a 2nd hand shop and couldn't resist. Just bought it cause it reminds me of my childhood. it was in my junk box for a while, one day i thought lets hack this to something useful and put it on youtube. Finally i came up with this simple idea, why not making a light? cool ! for study and for work, meanwhile it looks cool to be on the table but now has a different job, not phone but being an LED Light, who cares :) enjoy watching pictures of this project.
