Being able to simply press a button that would add as many credits as you like into the machine would be awesome!
Hey member “stayouttadabunker” did this DIY circuit board for adding credits to machine link here: https://newlifegames.net/nlg/index.php?topic=2044.msg15303#msg15303 (https://newlifegames.net/nlg/index.php?topic=2044.msg15303#msg15303) ever come to fruition?
This would be awesome if this ever made it to the finish line as I would love to rig this up on my S+ machine.
Unfortunately, the thread seemed to die off.
Any of you know about assembling such a board or something similar that would do the same thing?
-
haha...Holy old thread Batman!!
I never bought the gadget, but I did make my own free play for an S+.
It's really easy...you won't be able to use the bill acceptor, or drop any coins but it's pretty simple to do.
What I did was solder two wires ( about 2 feet long) to the Service Credit button on the coin-in optics board, underneath the coin comparitor.
Run two 2 wires to the two normally-open tabs on a button switch.
Remove the Bet One Credit button switch out from underneath the button deck, (let it hang freely) and replace it with the one you made.
Then, disable the door optics by disconnecting the 2-pin harness from the door optic.
Turn on the power switch and close the door.
You can press the Bet One Credit button up to Max bet, and hit the Spin button all night long for free! :rotfl:
Have fun!

Hi Stayouttadabunker,
I was hoping you built the circuit board that member “dupuhini” designed and was building at the time. His circuit board would allow you to issue as many credits into the machine as you wanted with just one press of a momentary button.
All the instructions were available for free download in his post here: https://newlifegames.net/nlg/index.php?topic=2044.msg16402#msg16402
Does this ring any bells?
Many were in a frenzy about it at the time & over 300 people downloaded it! Heck, I downloaded it too yesterday just to see what it was.
I was hoping you followed through with the building of that board so you could share how well it worked.
-
I've made several coin simulators for S2000's and they work very well. I don't see any reason why it wouldn't function in an S-Plus with a harness change.
They are Arduino based, I use UNO's and NANO's.
The code can be modified to pulse for 1 coin, 2 coin, 3 coin and more.
If interested I'll put together a build file.

Hi Stayouttadabunker,

haha...I was wondering what a small bag of PIC16F84A chips were for?
I still have them. :rotfl:
I guess I started to collect the parts needed to build it, but got too busy too finish it.
Life gets in the way! :Tongue_Out:
-
I recently designed and built one for my test fixture for S+. It also simulates the hopper so that it can be removed. I was thinking of building some to sell but it doesn't seem like there is all that much interest.

Just curious guys, my machine is a 2 coin max quarter machine S+, it will only allow for 2 coins to be inserted at one time for 2 credit play. If you use the tiny white service credit button under the coin comparator it will only give 2 credits max as well. So, my questions to both of you are:
1. Will your device override the 2 credit max & let you put in as many credits as you want at one time without restrictions?
2. Example: Can you make it give 80 credits with just one press of the button similar to like putting a $20.00 dollar bill in the validator & it gives you 80 credits?
-
You need a different SP chip to allow that. SP1137? Mine will put a single credit in if you just press and release the change button. If you hold it down it will continue adding credits at about 3 per second. It does not just add 80 credits all at once. The BV will still work as well.

That would be fine too, just don’t know how to go about doing it.
-
Contact RB...he'll have the chips you need...tell him I sent you! lol
That SP1137 is the ol' Montana Credits chip that allows you to drop in all the coins you want.
You still can only MAX bet up to whatever your game allows, but it's fun when playing with coins, to drop in a whole handful and play....lol

Hi Pitts256,
Wow, your machine looks brand new, super shiny!
If I knew your simulator would work on an S+ machine I would ask for a build file, but being there is a high possibility it may not, I wouldn’t want you to go through all the hassle.
-
With the boards I've built you can push what ever button you've chose on the deck to use for the simulator, I use the SPIN button on the S2000's and would use the CHANGE button on the S+. Depending on what your MAX bet is the board can be programmed to pulse for one, two, three or five coins with a single push of the "SPIN" button. As lookes mentioned if you have a specific SP chip the number of times the board will pulse per a single button push is endless...the coin pulses will go directly into credits, like the bill validator but only much slower. I've never set one up with more pulses than what's needed for a MAX bet on a single spin.
-
Thanks on the machine comment. It was a restoration for a local customer.
No problem putting together a build file, I'll post it tomorrow.

Hey Stayouttadabunker,
That sounds pretty cool too!
I may consider that, thanks!

I've never set one up with more pulses than what's needed for a MAX bet on a single spin.
So, let me get this straight, with “lookes” simulator along with the chip SP1137 the credits advance endlessly as long as you are holding down the button, but will then cease when the button is released. Please correct me if I’m wrong on that assumption.
Now with yours “Pitts256” you can program the simulator to issue any number of credits with one press of the button without having to hold the button down. You’ve just never tried that yet?
How am I doing so far understanding all this?
-
Yep, I've tried multiple ways...it works.
With the main door closed and the machine functioning as if in a "normal" play the coin simulator board will work both ways.
OPTION 1: Push the CHANGE button one time and the board will pulse the MAX coin bet (2, 3, 5 or more coins). The MPU will INHIBIT any more pulses from the board when the MAX bet is reached to avoid a "coin-in tilt" and disables the board while in play.
OPTION 2: With the SP chip change the coin simulator board can be set-up add 1 coin at at a time while the CHANGE button is held down or with one push add what ever number of coins you choose to CREDIT.

Wow Pitts256,
That sounds great and what I’m looking to achieve. I think it would be a great option for any machine to have in a home environment.
I’m looking forward to the posting of your build file; I already have an Arduino sitting in a drawer for a project I never got around to building. Never used it & completely forgot about it until you brought it up in your post. I attached a picture of the one I have & believe it will do the job, let me know. I’m not very familiar with them, but think this will be a fun project I can handle with possibly a little help from your end.
Thanks again!
-
No problem putting together a build file, I'll post it tomorrow.
Hi again Pitts256,
Just wanted to re-open this thread in hopes you haven’t forgotten about it.
I am still very interested in your build file and excited about implementing your project into my machine.
Hope all is well,
Thanks, twinfire

Hello twinfire,
Sorry about the delay.
I've found the S-Plus slightly different than the S2000 with the method of inhibiting the coin comparator, the S-Plus uses an AC voltage as opposed to DC for the S2000. Also the optoisolators I'm using are a bit too slow for the S-Plus. So I've changed the schematic, the Arduino sketch and ordered some parts to build a prototype for testing. Shouldn't be too much longer once the parts arrive.
I was able to make a modified S2000 model work well with several additional components but I need to clean the prototype board up using the new parts and then test.
-
Hello twinfire,
Sorry about the delay.
Wow Pitts256, no apology needed whatsoever!
What you are doing is awesome! I had no idea you were in the process of building a new prototype coin simulator version for the S+.
I am exited & looking forward to this,
Thanks again Pitts256
-
Well I finally got around to working on the S-Plus coin simulator project(s).
I made three prototypes all using a NANO board.
1) Using Darlington transistors
2) Using solid state relays
3) Using mechanical relays
They all worked without issues so the configuration adapts well utilizing different components.
I've attached a build file for the simplest of the three. If you have any questions feel free to ask.

Great Pitts256, Very nice! :cool_thumb_up:
… And yes, I have questions.
1. Does the coin comparitor need to be completely disconnected for this to work, or can it stay connected using something like a Molex Y- splitter cable so you have the ability to still use coins, or choose to use the free play option?
2. Will the door optics still need to be temporarily disconnected for it to work with the door closed?
3. Can you upload pictures of the boards you built so I can get an idea of how the finished product might look and also pics of what it looks like plugged into the machine?
4. Another request I have would be if you could post a YouTube video of your board in action working in an S-Plus machine would be awesome (I think we all would like to see this).
5. Is the Nano sketch you provided something that can be copied & pasted directly into the Nano, or does it need tweaking?
I have little experience programming the Nano so I would need the exact sketch that could be directly pasted into the Arduino IDE that would give 80 credits with one press of the button. I realize I would need to change-out the SP731 to SP1137 for it to accept the additional credits.
Sorry for all the questions, I’m just very excited about this project and getting it implemented on my S-Plus machine.
Thanks again Pitts256, Awesome job! :thank_you:

Yes the coin comparitor, coin optics and coin diverter solenoid will be completely disconnected. In fact I've removed the entire assembly from the machine and replaced it with the simulator. A Molex splitter will not work.
2. Will the door optics still need to be temporarily disconnected for it to work with the door closed?
The door optics will not need to be disconnected. In fact they should remain fully functional as in the original condition.
3. Can you upload pictures of the boards you built so I can get an idea of how the finished product might look and also pics of what it looks like plugged into the machine?I've attached three photos, the first prototype board is fully functional with the inhibit function and mini relays, the second with just the Darlington transistors. I also installed a socket on the second board to try some Darlington array chips, which worked well too. And the third photo is the board installed in the machine.
4. Another request I have would be if you could post a YouTube video of your board in action working in an S-Plus machine would be awesome (I think we all would like to see this).I'll give it a shot.
5. Is the Nano sketch you provided something that can be copied & pasted directly into the Nano, or does it need tweaking?The sketch must be copied and pasted exactly as shown otherwise you'll get a compiling error. The sketch can be tweaked later if you'd like to experiment with the number of pulses.
I have little experience programming the Nano so I would need the exact sketch that could be directly pasted into the Arduino IDE that would give 80 credits with one press of the button. I realize I would need to change-out the SP731 to SP1137 for it to accept the additional credits.You will need to change to the SP1137 otherwise any pulses more than the game maximum coins permitted to play will result in an error. The sketch is currently set for 3 coin pulses.
Sorry for all the questions, I’m just very excited about this project and getting it implemented on my S-Plus machine.
Thanks again Pitts256, Awesome job! :thank_you:
-
Pitts256, Thanks for the pics, hope the video is soon to come.
The sketch must be copied and pasted exactly as shown otherwise you'll get a compiling error.
I have tried to upload your sketch in the IDE exactly as you wrote it. I simply copied it from the PDF & pasted it in the IDE. Unfortunately I get a compilation error.
Since I’m new to Arduino, I no doubt am doing something wrong, although I have confirmed the Nano is good by uploading some very basic code that works.
Any ideas?
-
Copy and paste changes the format.
Here's a copy of the sketch for the S-Plus Darlington version.

Hi Pitts256,
I downloaded and opened the zip, clicked on the INO file you provided, hit the verify button and same result, compilation error.

-
Download the Bounce2 library.
-
Hi again Pitts256,
Downloaded the library and worked like a charm!! Thanks again.
Now I just need to round up your BOM, however you didn’t include the PCB. Which one do you recommend that best suits this project?
Is there a specific vendor you prefer ordering your parts from?
Thanks
-
The prototype boards off of eBay, the rest from Mouser.
-
Appreciate all your help Pitts256,
Looking forward to getting this all assembled.
I’ll report back to this thread as I move along with the project.
:yourock:

Hi again Pitts256,
You probably knew this was coming… yes I have more questions :sillyme: With my inexperience I’m sure you will find my questions amusing.
I realize you are using NANO’S for the simulators, but I’m a little concerned that the schematic you provided shows an Arduino Pro Mini which has a different pinout arrangement than the Nano. I just want to be sure to get the connections correct.
Questions on the schematic:
1. Is it safe to assume although they are different that the pin numbering 2 through 13 on the mini is equivalent to pins D2 through D13 on the Nano?
2. The pin terminal “RAW” on the mini I assume is equivalent to pin terminal VIN on the Nano?
The 12 pin Molex connector pinout:
Here is where I need some clarification. Your schematic is indicating terminal 7 is an ORANGE-BLUE wire that connects to Diode D1.
My S-Plus machines both indicate pin 7 is an ORANGE-GREEN wire; however, pin 8 is an ORANGE-BLUE wire, this is true on both machines.
3. Could you please verify the pin terminal and wire color code that connects to Diode D1?
Chasing the Parts:
This is where I’m having difficulty. One would think that with part numbers it would be a no-brainer to locate parts. Unfortunately, when the part is discontinued, or updated the part numbers change along with the electrical specifications, tolerances etc.
Since I am a complete novice this is where I get lost.
I have little experience with these components and with all the different variations, electrical specifications and tolerances of virtually the same component I’m not sure how to recognize a suitable substitution for a particular application.
Pitts256 this is where I need your experience and expertise.
At this point I’m just looking up the parts. The LM7808 shows up outdated, out of stock, or obsolete. From what I have found, the L7808CV seems to be a close equivalent and readily available through Mouser, DigiKey etc.
4. Do you think the L7808CV would make a good replacement for the LM7808?
According to Mouser, the EL817 is “Non-Stocked” and Lead-Time is 14 Weeks with a minimum purchase of 300 (no thanks).
5. Will a PC817 work in place of the EL817?
6. If neither the L7808CV nor the PC817 will satisfy the requirements of this project could you please recommend a substitution that is easily available?
7. As for the resistors, ¼ watt ½ watt, or does it matter?
Sorry again Pitts256 for all the questions, I just don’t want to screw this up.
Thank you.

2. The pin terminal “RAW” on the mini I assume is equivalent to pin terminal VIN on the Nano? Yes

Pitts256, thank you for the clarification, I feel confident now on getting the correct parts ordered.
I will update as things progress.
:thankyou:
-
Sounds good!
Let me know if ya need more info.
Also I've been beta testing a Darlington array chip that consolidates some parts. I'll put together a schematic and send your way if interested.

Let me know if ya need more info.
Thanks, I appreciate that immensely.
Pitts256, since you've been creating several different ways to build a better coin simulator, I think you would be very much interested to read about what member ersk3 discovered about the hidden 3pin connector inside the door of the S-Plus machines. Apparently with his research and experimenting he was able to add credits to the machine by simply sending 50ms pulses between the purple and green wire of this mysterious 3pin connector.
Unfortunately, all the pictures and videos he posted are long gone, but you can still make out the basic idea of how it works.
Just for kicks I checked my machines to see if the 3pin connector was there and it is! It is tucked back in the wiring and hard to see/find.
Pitts256, with your knowledge and expertise I’m sure you would be able to very easily figure out how to deliver the 50ms pulses between the purple and green wire. Maybe by using the Nano the pulses could be delivered into the machine more efficiently adding up the credits quicker similar to how the bill validator does it.
Check it out and see what you think, here is the link: https://newlifegames.com/nlg/index.php?topic=15051.0

Awesome work ! !
Anyone know if this will work on a PE+ with Superboard?
-
Yes it will.
The J/P 301 plug configuration is the same.
-Pitts256
-
Great !
Thanks for all your hard work on this!
-
How are the projects going?
-
Hi Pitts256, well, for me I simply got caught up in life. My slots and the project have been put aside for the time being, but do still however plan on implementing the coin simulator as time permits.
The thought of using that 3pin connector for adding credits to the machine is very intriguing since the coin mechanism could stay operational.
Have you given any thought to that?
-
I've checked into it.
I traced it back to the CPU board, it's labeled "IR DET M+ (SERV/CHG) S" on the schematic. The plug is a live input to the CPU and I'm assuming it is for an input device mounted in the place of the SERV/CHG switch. Sending pulses from the plug to the CPU did nothing.
-
How are the projects going?
Life also has me distracted from working on this. Not enough hours in the day!! Still plan to put this together when I have a chance.
Does anybody out there have one of these already assembled and working they'd like to part with??

Pitts256, I’m surprised you got nothing from sending the pulses. The only thing I can think of is you didn’t have the correct chip in place when you did the test?
According to member ersk3 at the time of his post (March 09, 2017) either chip SP585 or SP1168 were the only chips he was aware of that would accept the 50ms pulses that convert to credits.
Now it seems as of (2021) ersk3 has listed these chips: SP585, SP618, SP655, SP667, SP674, SP714, SP 742, SP765, SP876, SP1041, SP1138 & SP1168 as being compatible to work with the 50ms pulses. These chips are found in the list here, you will however have to download the list: https://newlifegames.com/nlg/index.php?topic=33460.msg177252#msg177252.
ONLY the chips identified with (Yes) in column “NRI coin acceptor according to PSR” are the likely candidates that will work. Notice that SP585/SP1168 are among the list & are the ones that ersk3 experimented with and were found to work. NOTE that SP1137 (Montana chip) is not listed.
I’m guessing your test was conducted with the SP1137 chip as this would be a logical choice not knowing about the SP chips for external coin acceptor (NRI) that administrator knagl mentioned here: https://newlifegames.com/nlg/index.php?topic=15051.msg80738#msg80738
How are the pulses to be delivered to the purple & green wire, not sure I understand exactly how this should be done? Maybe you could elaborate?
