I really did not need the next " Arm for iPad " , but after finishing it , and mounting it to the wall beside my bed , i found it very useful !
you don't need to actually hold the iPad, you can swivel 360 degree , and it`s actually very handy
I used one of my unused Desk light fixture.
Disassembled it`s end , removed the wiring , and assembled some tablet mount i purchased from eBay
Attached it to the wall , and that`s it, i`m ready for some chilling on my bed with the " iBed " :)
