Now the main problems with coin comparitors/acceptors that I have gathered from different sources is that they jam up, the only way it would work is if the coins fall single file.
I took apart my coin counter which is the same model as this one...

When the coin rotates around the disc the coins fall into the hole that it fits in and there is a sensor in the hole that counts the coin. Ive played around with the senors in the holes and it seems very accurate. I rapidily moved my finger in and out of the holes as fast as I can and it seems to track every movement... also, It doesnt seem to get confused when I stick 4 fingers in 4 different denomination holes as fast as I can, it still keeps up. I'm assuming this sensor technology is cheap and available, since it is just tracking movement, not coin size or material.
Now, what I want to do is, get these sensors and a read out display connected to tubes that would be connected to a Klopp coin sorter, since it sorts each denomination and puts them in its own bin.

Do, you know where I can get these sensors and a digital number count display?
Secretly I'm hoping my counter breaks down, so I can rip it apart and use the sensors.

I would be willing to pay someone to build these tube sensors with the LED read out. I don't need these things on a commercial scale, just 1 unit, possibly another 1 in the future.
I was wanting 6 tubes (each coin), with a small motion sensor in each one with wires about 5 - 8 inches between each tube and extra wire for the LED so I can figure out how I need to mount everything.
I will have a delivery system for the coins, I'll probally use that "Klopp" coin sorter, so the coins will have some control. Each denomination will go into its own tube.
I live in Vancouver Canada.

If you know anyone or company that could help me out with this project, please let me know.
Thanks,
