I am trying to find out how coin accepters work. I understand putting one coin in of a certain value triggers a microswitch adding a credit. ......BUT...how do the coin accepters work that you can put a few difference values of coins in to add up to one credit. For example, if 1 euro is needed for a credit, how can they accept 50 cent, 20 20 and 10 cents to trigger a credit? If you know what I mean. Or do the coin accepters only accept 1 type of coin? Thanks |

sure there is something like that but it might be to much $$ or way over head for a CAB for home. What if they put to much, would you want it to give change too ;D Why not just hack one that accepts any SIZE coins and gives 1 credit. |

In the USA, we pretty much decided long ago that our machines would just take a single kind of coin (usually quarters), and we set the games to require X coins for a game, and that's how the pricing is determined. We also often have bill acceptors (since dollar coins are not in widespread usage) that hook up to the game board via a separate input, and the game knows that the value is different and will award you the appropriate amount of credit. Most bill acceptors can also be programmed to output the appropriate number of "coin pulses" (e.g. 4 for a dollar bill) to simulate the player putting in 4 coins if the game doesn't support bill acceptors directly. In many other countries, the use of other size coins is more widespread, so "credit boards" are common along with a more complicated coin mechanisms. Rather than simply passing coins of a certain type to a switch and rejecting all other coins, these coin mechs determine what kind of coin was inserted and signal some electronics to output a number of pulses that varies with the kind of coin. E.g. putting in a 10 cent coin would give you one credit (by pulsing the coin signal once) but a 1 dollar coin would give 10 credits (by pulsing the coin signal 10 times). This is more complicated and prone to failure than the single coin only system, which is probably why it's only used where lots of different coins are common. I'd say this is probably way more complicated (and expensive) than can be justified for a home system, too. |

Thanks for the replies! I am planning on making another jukebox and cab that I will probably end up selling on, and it would need this type of coin accepter to have any chance of being sold quickly. (which I found out last time I sold my jukebox). I googled and found some that connect through USB/serial and accept 6 different type of coins. The ones I found were about $120. I'm just curious as to how this would register with the PC or jukebox software. Using a keyboard encoder same as the others probably ? Here is one for example http://coin-acceptor.com/ The bit thats confusing me is that as you say if for example it requires 1 euro for a credit, would it pulse for each 10 cent added (smallest denomination) or would it hold off until the full amount had been received before sending the pulse to the PC? Because if it sends pulse for each 10 cents I've no idea how to configure this to MAME or jukebox software. Thanks again |

Under a police investigation, since you built it, you're the responsible party. Certain entities are beginning to pursue people for this so I'd look at other sources for extra income. :angel: |
