Finally, the Universal MP3 Sound Board Has Arrived

I like it!

Looks good! I had questions, but the document answered them.

Very nice!  I've got recordings of a flat wheel car and flange squeal that I used for Microsoft train simulator, they're already MP3. I also plan on using something like this for ambient sounds for a Diesel facility.

Nice job, John.

Cool!  I was wondering if someone was working on something like this, guess it makes sense that it was @gunrunnerjohn.  I bought an old MTH "Freight Sounds" card that plays "Christmas music and Santa Sounds" on a random pattern.  The trigger is a little pendulum weight centered in a circular cutout of the PCB with a ring conductor.  It takes up the entirety of the boxcar interior and the sounds are...um...nominally Christmas-ey.

Using the trigger and speaker from the MTH board, this seems like it would open up a lot of extra options!

The wheel speed sensor was something I was going to ask about, but saw it mentioned in the documentation.

Looking forward to see how it plays out! (get it...plays out??)

Thanks guys, it's been a long time coming.  I'm still working on the wheel speed sensing board, that will be an add-on when it's ready.  I actually have the completed boards, but the software that looked great in the breadboard seems to have issues in the actual hardware, need time to see what's going on there.  I hope to have that ready in a couple of weeks, the holidays have kinda' infringed on my development time.

Looks pretty slick!!

Nicely done John.  The PDF file provided valuable insight into the capabilities of your product.  Maybe a future YouTube video demonstrating the application of the board would be a great way of getting the word out and generating sales.

Thank you so much for making this. I wish it existed when I was doing some of my prior projects but this will make future ones easier. Sign me up!  Would love to be an early buyer!

A video might be cool when I get the wheel speed sensor board working, that would really showcase what you can do with the unit.

I'm working on the "final" assembly of some boards.  While they come in with the basic components soldering, I still have to integrate the MP3 player and RF receiver after they arrive.  I also have to get all the cables sorted out, but I'm close.

I have more to add to the documentation, but I figured I'd get it out and let people have a peek at it, and maybe even make a suggestion or two about making it better.

Will this need a choke for use with DCS?

Very nice job John!!!  One of my sons-in-law will help me with the MP3 audio.

John,

I've been messing with something like this for two years, off and on.  Actually made a board that I used for another MP3 project (lightning and thunder) and added an RF receiver.  Never had the time, energy or interest to take to completion.  Procrastination has it's benefits!!!!  I'll be stocking up on some for use in cars and around the layout.  Great work delivering a much needed tool/toy/innovation.

John when you get mine ready as we discussed i would like the speaker you showed me  me with the baffle cover over the speaker if you can tell me the part number and where you purchase it! believe the small speaker will, fit in a box car possibly!

Joe, all my products, including this one. have the 22uh choke for DCS compatibility.

Joe, we should all know by now that John thinks of everything! 

Well, that's a little generous Mark, but I did think of that issue.

I like being a generous guy!

Hmmm.  Almost bout a Bluetooth device for a project but might rethink that.
