The 3M 7″ Capacitive touch overlay finally arrived.

All I can say is I’m sure 90% of the cost of shipping went into the ridiculously large packing, but its in one piece and is sweet.

So here is a mock-up So we have VGA to composite powered by USB. Composite to a 7″ LCD Screen (spare from another project) and then the 3M USB capacitive touch overlay on the monitor. After installing the 3M calibration software it works perfectly. Now to get a LCD bezel to modify.
