Adafruit Mini Sound FX Board Wiring Diagram

I have worked out a wiring scheme (above) for the mini Adafruit 2MB Sound FX Board for supplying power to the board, wiring up the momentary buttons that activate the sound FX on the board and the audio out jack.

The power supply is simple, I'm basically using the same 12V to 5V step-down converter (right) or transformer model that I used for my GPS screen, I solder the 5V output wires onto the Adafruit board. I may introduce an on/off switch into the wiring scheme to have further control over if the board is powered or not. If I do I'll probably do that on the 12V input side of the step-down converter module. A simple switch to Relay should work well for that.

The momentary buttons to activate the various sound FX on the Adafruit board I will hook up to both my Lower Console's Space Matt buttons and my Switch Pod buttons. So far on the sound FX board I have:

1. Knight Rider Theme (Narrated)
2. Knight Rider Theme (Un-Narrated)
3. File Open Sound FX
4. File Close Sound FX
5. Scanner Sound (Loop)
6. Radar Sound (Loop)
7. Turboboost
8. K.I.T.T. Introduction
9. Surveillance Mode FX

I have a little room to add more if I like but I think for anything more complex I will get the 16MB version of the same board in order to use more sound if I find I need more. But for now these should do for simple things.

The Knight Rider themes I have set on the board to play in next order so when you press the button the first theme plays and at the end of the theme when you press the button again the other version of the them plays.

The File Open sound FX I have sent to just play when the button is pressed, my thought is that I will have those sounds play when I turn on the LCD Screen or GPS Screen.

File Close sound FX will play when I turn off either monitor.

Scanner sound FX loop I have set as a "Latching" function on the Adafruit board, the sound plays until the button is pressed again, so looping sounds are best for the boards "Latching" function.

Same set up for the Radar and Surveillance sound FX loops. 

Turboboost FX is set as just a single play on button press same as K.I.T.T.s introduction. I could very easily add other introductions and have those play in a random order as the Adafruit sound FX board has a very nice feature for playing random sound files too, but for now I'm just using the classic K.I.T.T. introduction ;)

Here is a little additional work done on the diagram to include a power on off switch and to use the option of either a Relay or Optocoupler as switch option for the momentary button to activate the board sounds.

Adafruit Mini 2MB Sound FX Board Test

So I finally got around to testing out the Adafruit 2MB Flash Sound FX board I had picked up quite some time ago, I had been meaning to get around to it but was constantly getting side tracked with so many other projects. Today I hooked up the USB cord and plugged in the mini board and copied over the WAV and OGG files with the correct naming convention as per the instructions on the Adafruit web site. The board works like a charm and is very simple to use just like they say. This will be perfect for some sound FX that I know will get used a lot and I think should be built right into my K.I.T.T. project. I have a demo video here, I do apologize for the focus though but it's gets the point across as to what is going on and how easy it will be to hook up these contacts that activate the sounds on the board very easily to some of my Switch Pod and Space Matt buttons.

Received The Adafruit 2MB Audio FX Sound Board

I received the 2MB Audio FX Sound Board by Adafruit, it was dropped off late yesterday by UPS. Now all I need is the step down transformer to convert 12V DC to what this little board needs. Once I get that I can begin working on how I want to incorporate this into my dash to work with the switch pods. I know for sure I want it to reproduce the Turbo Boost sound when that button is pressed. Some other sound effects too that I'll see if I can work into my K.I.T.T.s Voice Projection System. It's going to take some figuring out but this tiny little board which was designed for props is small enough to stash just about anywhere.

Switch Pods To Sound FX Plan

I found this really cool little Adafruit Audio FX Sound Board WAV/OGG Trigger with 2MB Flash that I figure I could use in conjunction with my Switch Pods to make them play certain sound effects, like for instance if I press the "Turbo Boost" button I should be able to have the sound effect play through either the car's internal speakers or even through the Voice Projection unit loudspeaker mounted into the front nose.

I found this very cool little sound FX board after watching a very cool video by James Bruton of XRobots on YouTube. Check out this cool video and you may begin to see where I am going with this ;)

As you can see from watching the video it's a very easy board to use for props and you can put a lot of sounds on it. The board looks to be small enough to easily stash just about anywhere.

Now one of my concerns was about how the board is powered, for props as you can see it is just a matter of hooking it up to a small battery pack as the board runs off of a 3 - 5 V DC current. Now the car electronics run on a 12V DC Current.... So I remembered that there is a little thing out there called a "Step Down transformer" so I thought to myself;

"OK, before I go and shell out the Frog Skins for this cool little board let me see if there is such a thing as a Step Down Transformer that will convert from 12V DC to 5V DC?"

And guess what? There is! I popped onto Google and did a search and sure enough I found this little gem on eBay for a great price and best of all it's even made to work with the Arduino boards. 

Check out this very cool video that also shows how this Adafruit board can be used.
