Hey guys :D
I have a glass table which have a white layer on the bottomside (paint of some sort) LEDs can shine through it.
I'm thinking of making it in to some sort of control surface... so I ex. can tap at one location and then it means start etc.
What is the cheapest way to do this ?
the resolution doesnt need to be more precise than 10x10 cm (surface is 70x120cm)
I have an AtMega32 right now for this project :)
