Hello \
I am brainstorming about a project that involves a statistical count to calculate the number pi. The problem is consisted of a flat surface with 2 very thin parallel lines separated from each other distance "s". I now release a matchstick like piece on this surface that also has length "s". All I need to be able to do is to detect a hit if the matchstick is in contact with one of the lines on this surface.
I though of a simple switch as the surface could be differently charged than the parallel lines and the stick could be simply wire acting as a conductor, however, As the medium is water or oil the conduction property will fail...
I am open to any suggestions from image processing to capacitor/resistance sensors. really anything that is out there that can help.
Thank you in advance!
I d appreciate any help/ pointers on this.
