Need to find or build touch sensitive LED lights

[superskid]

My question isn't directly related to building a MAME cabinet, but this community has taught me a ton just from reading and I think can help me with this project.

I have invented this game we play every New Years called Drinko (it's a Plinko board with different shot on the bottom instead of $)  Every year we try to make it a little bit better, and this year I want to add LED lights.  I would like the PEG to light up when the chip hits it so you will see the light trail of it in the dark. 

If anyone good help me out on building this it would be greatly appreciated.

Thanks,

can you post pictures of said drink board so that we can blatantly rip off your idea help you.

It seems a simple answer would be to use regular switches to turn the lights on as the plinko thingy passes by.  If you wanted to just light up the drinks at the bottom that would be easy.  How many lights we talking about here?  Do you want the lights to turn each peg on after the plinker hits them?

I will get a picture up shortly.

Do you mean switches that the chip passes over as it is dropped down?

The board is 8 pegs wide by about 16 pegs tall.  So a total of 128 pegs that I would like to light up as the chip hits them.

Thanks,

You are probably thinking of some sort of capacitive or touch sensing.  That would require 128 units for 128 pegs and the plinko might not carry enough capacitance to trigger it.   I think you really have to think outside the box for this to work.   How about the  pegs being made out of metal and being insulated from the board or base.   When a metal plinko hits it the circuit is completed and power from the board or base goes to the peg that has the LED and resitor in it.  Shazzam we have a blinking peg.

This is an interesting idea, but I would need some help designing such a board.

not sure if you are still looking towards making your idea work but maybe finding a way to use kaytrim's 'bling' effect (button lights when pressed) would help you along the way.. maybe not but its a start..
