Quoted from docquest:
Is this sound card mod a one off for your project or is it something that can be purchased?
We are thinking of selling them. Jeremy designed the circuitry - and programmed them . there’s a fair bit to them as you can see. Basically a small computer and an MP3 player merged together, and made to accept 6v AC inputs to change the tracks.
The way we have set it up ...
4x inputs for player tunes.
- player tunes will play continuously- well, as long as your ball lasts.
1x game over tune
- plays only once
1x tilt tune
- plays only once. I’m going to record some funny speech for my one.
All the tracks are MP3 and can be changed to whatever you want.
They have a built in amp (low power) and an Aux out so you can run it to an amp, or something like a Bluetooth/Aux player. Terry at PBL has Marshall Bluetooths on the top of his KISS and Nugent and they look pretty cool.
These are designed specifically for EM machines, just to play background music. Like I’ve said elsewhere in the thread, I don’t want my EM to make sound effects when the ball hits switches - that’s what the chimes are for. Chimes are the essence of an EM machine, in my opinion. If you don’t want chimes - don’t get an EM.
We did some preliminary pricing - to make it worthwhile making them, they’d have to be around 125-145 bucks - every one is made by hand. Obviously they’d be cheaper if you got a company to make 100 of them, but I don’t think we would need that many.
Any interest around that price?
