Coin Acceptor with RecalBox

[IvoLourenco]

Gents,

I’m building a arcade table using Recalbox. My system is fully working. I was thinking on adding a coin acceptor to it for fun. But I could not found any thread on this matter. (Inlight me if already exist)

The current setup has two players and uses a two independent buttons for insert coin on each player. What I want is to replace this buttons by a single coin acceptor?

I know that is possible with retropie in parallel with a zero delay card. However, I want to connect it through GPIO. Probably I would need to have an independent energy source as it is 12v.

Thanks in advance for the support.

Ivo

Hi,

There's a french tutorial for a single coin slot. Dunno if there's english version, but maybe with Google translate...

@kjbstar Thanks for the input. I´m afraid there is no way to use a single coin acceptor to replace both buttons. If there is any other information that someone can have will be welcome.

Hello @tong-man, i noticed that the link mentioned above was developed by you and reference on your youtube channel. I noticed that your bartop as two players. So my question is: When you insert a coin your credits are assumed as 'general credits' and both players can take them?

Thanks in advance for the support.

I put coin acceptor, but I used encoders, it should be the same with gpio buttons. Just necessary to separate 12V from 5V. you find the schematic that I use on my bartop here :
https://forum.recalbox.com/topic/11344/1-bouton-select-branché-sur-2-encodeurs-usb
I switch both select1+2 with one 12Volt button on relay, and I can also choose between freeplay or coin, with illuminated select(s) button in case of activity.
I put also modification to exit the coins behind instead under, more place.

@Dragu I did not fully understood your schematic, i already bought the relay and now I'm planning on getting the PCB to create the interface. I believe i understood the philosophy behind. Basically you insert one token and it flags on both encoders. But in that scenario 1 coin gives always two credits. So if this thinking is correct you would be fine to use @tong-man solution with a split wire at the end, so I can connect to both GPIO pins, no?

As example Neogeo. If you push/insert, he consider 2 players and add everytime 2 coins. For be able to play as 2 you would otherwise need to insert 1 coin/push, but on every Select separate. Its up to you to choose.

Hello @IvoLourenco , into "dips switch options" of the neogeo, mame and fba systems, u can affect the "insert coin" button for the 2 players. U can also affect x coin for x credit for each players etc...
