hello,
my basic idea is to have a case for my iPhone, with a layer of antistatic conductive foam stood off of it about an half an inch. Then, I will have an array of linear actuators press down on the foam to simulate a press...
I know it's not the most practical thing, and the resolution of the presses would be great... but it still might be fun.
the thing is, linear actuators seem awfully expensive, and big...
is there something else I should be looking for instead?
