wow !! so it s like a pinsound project but for gottlieb pinball

i love it !

could be so nice on pinball like stargate... ( system 3 )

Hello

I thought back to your project.

concept (resized).png

If I understand correctly the difficulty is to do the mapping of the 8 A6P1 inputs to an arduino mega 2560 (and then drive a wav trigger. like https://www.sparkfun.com/products/13660)

I may also be doing a test since I have all the tools on hand.

Did you manage to understand how is coded the 8 inputs A6P1?
I suppose there must be a matrix to define the coding to pass to the map 'S4 ribbon'?
Or the coding remains simple with a single pin to 0 and the switch is in operation of a clock?

good luck and if you can share the matrix I could try too

++

could you share with us what is the logic of the 9 pin plz ?

thank u

see you

Hello

here is some first quick test i just did with an arduino to "read" the matrice sound :

we can see on the second line the inpit value change from 0 to 1....

the big work part is ( for the software ) to "define" the matrice ( 0001001001 = what wav file ) and the rules between musix & voice & fx ( repeat / pause / replace / interrupt )

i suppose the hardware part is the easyer of the project... ?

see ya

Yo

so i success replace the sound board.

Have still some tuning to do but it works.

Now i just have to replace the original wav file in the sd card. And put some logic for random sfx some time

I got all wav sound using Pinname with stargate Roms.

recording and cloning protype :

the one that replace the sound board :

video coming for last prototype.

i am unsing and arduino mega and a wav trigger.

the raspberry is use only for remote setup & monitoring.

at least i hope replace the arduino mega by a nano one and maybe find a wav trigger cheaper

So for information the sound code is code on 8 bit.
If you put the bit in the good order and convert the binary to dec you got the same number of track you extract from Piname.

then you have two binary number for control :
0 = stop
126= ( or 128 d'ont remember ) = cross fade.

Music track call replace each other.

that s all...

Sorry man, I thought the project was abandoned.

Since I had no response from you in mp...

If not in the end I finalized the concept and I will do another post as requested.
Good luck

sorry again. my intention was only to share ideas between passionate people.
I absolutely did not want to do any harm.

And as the subject was similar I thought I was in the right place ...

sorry again, i hope you will succeed
