Magnets, they're not fixed to the back of the pad tray yet only as I want to bed down all the major work first.
Basically glue a strip of magnets at the back and it won't move an inch.
Glad this is providing inspiration to others.
Okay so it takes a lot of work and you could pay someone a heap of cash, but this is so much more rewarding.
Any magnets in particular? I thought of that by buying an ipad mini case with the magnetic strip for the front cover in the hope of using that, but it doesnt attract to the phone, maybe iphones are made of different material?
