Fun with magnets

Got fed up losng my phone under stuff on my desk, so I wanted to be able to have it attached somehow to a vertical surface...

I thought of using a car grabber thing, but then I thought of magnets....

Ordered a bundle of super string doughnut magnets from Amazon. Glued 4 to a spare phone back that I had for my Galaxy S3. et voila, my phone sticks to any metal surface - Fridge, metal plate, etc...
At work I have a metal plate intended for use with magnets to hold papers : I inclined it at about 70deg and it holds my phone up out of the mess and visible at all times...

I'd take a photo, but I'd need my phone for that...

So, I still had some magnets left.... and when we got a new micro video projector at work, it didn't have a way to mount it onto a tripod (to hold it up off the desk to be able to project on the wall easily).... solution: a metal plate (a server 19" rack mounting ear...) attached to the tripod screw, and 4 magnets glued to the bottom of the VP...
Holds it perfectly, and allows easy manipulation!

Now I'm thinking that it should be possible to make my own 'magsafe' type power connector with these things...
