This board has been in development for quite some time. One of the holdups was finding suitable MP3 playback modules. The ones we used take a standard SD card and play files in the .MP3 format. You simply record the sounds you want onto 2 x standard SD memory cards and plug the cards into the players.
This board has two players that are both stereo and have seperate volume controls. The outputs are mixed together and fed to both line out sockets (to enable the use of an external amplifier) and the onboard stereo amplifier chip.
The board can be powered by almost any secondary voltage found in most EM machines (20~50V AC or DC) ar a 12V plug pack.
It has eight inputs to trigger seperate short sounds and four to trigger longer background music. This allows a background theme or longer sound file to be run while seperate sounds for bumpers or gun shots are superimposed over the background music - both with their own volume control.
The inputs are designed to be wired directly across a coil (solenoid or relay) with any voltage from 5V~50V AC or DC being suitable. They can also be configured to be triggered from a normally open switch.
Here is the first prototype nearly assembled:

I have parts for these in my current container due in port late next week so, allowing some shipping time to Cairns and then assembly time, I should have finished units ready in about a month. Price is as yet unknown but they won't be cheap....I plan to have them available in single and dual player models to make a cheaper option available.
Here is the prototype working:

I have been looking for something like this for a while, but need a simpler version to basically start a song on start button and to finish at end of game.
I am asking you if it can be triggered to shut off the looping song at the end of a game?
Nice work @@*
Do you have a BALL PARK $ as yet?
-
The single player version would do your job perfectly. Use one of the inputs to trigger the start and use another to trigger a second file - this stops the first one straight away and starts the second one (which is just a file name but no music) so it effectively stops playing.
I could probably build a much cut down version for your application as it would save a lot of connectors, 1 x vol pot, 2 x opto chips etc etc???
Price - always a problem - not sure yet.....

Love your enthusiasm for trying something NEW. I’m up for one. #*#
Quote ‘price won’t be cheap’; I can foresee me spending many hours finding funky sound effects. That will be more fun, than worrying about any initial outlay.
-
great work, interested to see any updates including cost
-
Very interesting, nice work again Mike *%*
-
Imagine the surprise on a players face if they didn't know the sound board was in the machine when they went to play it :lol
Great initative Mike ^^^

I see the main use for this board in EM Arcade games that had an 8 track player for sounds. The 8 tracks are pretty well all stuffed and unrepairable now so this would wire straight in.
I will only have a fairly limited run of them when the bits arrive so anyone who is keen on one needs to keep an eye on the website in a few weeks time.
-
Awesome stuff Mike.. brilliant @@* @@*
Had there been something like this available when i built my home made 'Vortex' pin all those yrs ago i would've been all over it!
Maybe its time i started another home brew pin project #@# #@#
-
Any more update? My holy grail is getting closer and I REALLY want her to play The a Beach Boys over those beautifull chimes.

I stopped development on the power supply side of this board so they must be run from a 12V DC supply. A Jaycar plugpack would do the job.
Several were used in Daniels brilliant "The Block" builds with great success.
I have been told by a few people that they are too expensive so I haven't offered them on the website and I stopped making them up.
In fact my sell price is below my cost with NO time factored in......some projects simply aren't worth the effort.
I have 2 in stock ready to go at $260 each and that will likely be the last of them.
-
Well ill take one.. you know that
-
Thanks for the info, I was hoping for a much SIMPLER version as per earlier post.
Shame this didn't take off for you/ us.
While the price is fair enough, too rich for what I want it to do. The old iPod will have to do the trick and headphones!
Cheers Andy

Nooooooooooooo don't stop making them up the price stuff the tight asses there worth every cent
-
Not aimed at you Andy just bad timing
-
SPACE GUN just begs for this..

Ha ha ha , it's all good. ^^^
Better suited to early SS machines or custom jobbies I think, Chimes rock!
I like simple, just like me.

SPACE GUN just begs for this..
Yes would be perfect in an Em shooter if only I had one :(
-
SPACE GUN just begs for this..
I know it does - all the input circuitry and MP3 stuff and amplifiers work a treat but you need to find 12V DC and the thing that stopped me progressing it was the spiraling cost of it??? Several people who inquired and I mention a price LESS than the price in my earlier post had heart failure so I gave up on it.....the simple fact is short runs of anything like this require minimum size orders.
I am having the exact problem every day here in China - I wanted some table top hinges today for the Hankin tables - no problem, cheap as chips BUT minimum order size 5000 pieces (I need two per table).
I actually started on this project originally for arcade SS machines such as Gavins Space Gun......

Depends.. ive just re read Mikes post. We did trial one in Space Gun but it needed further work.. if it needs a 12v trigger then im out of luck as coils work on 28VAC
-
Ive got some great space noises to put on this if it can work on an AC EM game.. its surprising how a bit of sound can make a good game into a bloody great game
-
Want to know one of my little secrets to getting these sound boards to work on the block (system 11)??
Because system 11 use the relay so the same transistor can either drive a flasher or a relay we couldn't get them to work because the sounds would be firing every 30 seconds instead of just when the coil or whichever single item we wanted to trigger a sound. Took me a bloody long time to work this out and ended up being a very simple solution...

The inputs all work fine with coil voltage as triggers (they are isolated with optos) it is ONLY the power supply that is an issue....perhaps Daniel can tell us how he connected his units??
-
Then in that case power supply is not an issue.. I already have a 12VDC supply installed as I put RGB modules in the front of the cabinet to shine colour changing dots on the floor when the machine was on.. simple enough solution.. a 30W 12VDC LED supply taken from the mains input gives you 2.5A to work with.. plenty to run lights and sound

It should work perfectly in your machine BUT ask Daniel how he triggered his boards just to be sure (unless he has already said and I missed it?).

$260 was deemed too expensive? Wow.... We spend so much money on pinball mods. I didn't think it sounded too bad for the possibilities.

So you took the trigger off the coil that fired?
-
No we couldn't use the coils as triggers on the system 11 coils worked fine on our Custom Rocky pinball running from the coils but for the Block wi ended up mounting micro switches all daisy chained to the coil voltages and back to mikes board that way I could basically trigger a sound anywhere I wanted even ran two in series to activate the multiball sound
-

One of the issues for me is that it isn't just plug-N-play and requires a fair bit of 'nous by the installer.
This then creates a massive amount of work for me on an individual board install basis and I simply don't have the time.

Seems it would work OK for the gun game as these sit high at all times till sunk to ground.. no phantom switching. For an EM game, trigger can be taken off the coil firing or direct from a leaf switch closing. That's nothing that an EM person wouldn't be able to work out as you know, no different to fixing one. I can see that this could get complicated of someone was trying to expand the sound on an SS game and wanted to come from the boards.. but for an EM?.. is nice and simple... where do I sign up?
-
Yes nothing you couldn't handle even early solid state are an easy hook up even wpc wouldn't be an issue just system 11 with there alternating flasher/coil relays have given me grief
-
These would have been great as a replacement for chimes. Nothing beats the sound of chimes, but this would come close.
