Question: how do the coin mechanism and the payout hopper tie in with each other?

Hi all,

Later in the year I'm looking at building an MFME cabinet that will accept money and pay money out.

I have quite a few questions about this (which I'll put in separate threads to keep them 'on topic').

I've been doing some research on how to implement a "pay in" and found these two coin mechanisms...

I'm quite confident I can get the pay in side to work but I've no idea how to get the "pay out" side working.

Am I correct that in a real fruit machine the money falls into a "hopper"?

Does anyone know how the hopper receives signals and how it knows how much to pay out? Is it serially through comms or just pulses on different pins that fires out a £1 etc?

Also, does anyone know what I would be searching for on eBay to get something that would perform this function in my own cabinet (basically pay out based on a signal sent from MFME) ?

Any info you have on this side of things at all would be really useful to me as, at the moment, I have no idea.

Cheers :-)
