THIS MAY DAMAGE YOUR iPAD!!!
I AM NOT RECOMMENDING THIS, I RECOMMEND BUYING AN OFFICIAL APPLE SMART CASE!
I AM JUST SHOWING YOU WHAT I DID, IT MAY STILL BREAK MY iPAD !!
Thanks to lilitab.com for finding the locations of the iPad Air Wake/Sleep magnetic switch locations!
I found their article on this after buying a case for the iPad Air and noticed that it did not put the iPad to sleep when closed. Thanks to lilitabs' article (http://www.lilitab.com) i was able to mod the case with a couple of 10mm round neodymium magnets.
Step 1: Locations
The rough locations of these sensors are indicated in this picture.
You need to reverse the magnets so have one north and one south, not sure which one is which but if it doesn't work one way, try the opposite way.
I put the two magnets together and marked the two sides that attracted each other with a pen. I used them marked sides as they were opposite.
Step 2: Magnets
I cut it into 3 x 10mm parts and rounded them off with a pair of cutters.
Step 3: Install Magnets
I also cut the cardboard away to allow the magnets to fit flush.
Step 4: Glue Back Together
Seems to work fine, just hope it doesent kill my iPad!!
