What about using something like this www.emartee.com/product/41928/MP3%20SD%20Card%20Sound%20Module and "hacking" it into the existing sound board?

My plan was to trigger tracks from the Arduino I'm already running inside my 7e, triggered by the switches run through the Arduino. I also figured that I could read the 7e's buzzer output and have that trigger sounds. That would only allow 4 sounds to be triggered by the Devo itself (4 alarms limit).
Unfortunately my board was DOA. I'll get a replacement,..........eventually. The first one took over a month. Slow boat from China.

The only Arduino I'm running right now is on my 250 quad. Its bluetooth and sends flight control info to my cell phone and allows me to make changes without connecting to my laptop. I have only looked inside my Devo8 one time ad that was to re-solder a bad connection. I would be happy with different alarm sounds (not beeps) if that's all I could get. I'm not familiar enough with the electronics of it to actually figure out how to wire a sound board in. I know the Turnigy 9xr has been hacked to fit a sound board. Yeah I try really hard to not buy from china.

The Devo's sound system is pretty much like Arduino's "tone" function. A pulse-driven piezo speaker/buzzer. That pulse could be read and trigger a soundboard playback. Again, limited to only 4, maybe 5 counting the low battery alarm. The piezo "tones" would have to be set unique enough for the Arduino to differentiate.DOONBY4797 wrote: I will crack it open tomorrow and see what I can figure out. Whatever is sending the sound to the speaker hopefully is easy enough for me to find. I'm not familiar with the electronics of these TX or any TX for that matter. Not sure what Taranis is using but seems to me it can be done
Pure speculation here, but I think the Taranis or 9xwhatever mod connects a sound module to SPI or something. If that's the case, one could be added to our radios, but probably limit us to 1 added RF module.

Trouble is, you'll have to disable the RF module in order to have them play a sound. Not clear how well that will work. In particular, can you enable it, start a sound, then disable it as you don't want the RF module disabled for the entire time a sound is playing? If you can do that, then even if disabling a module causes it to drop the RF connection, the MM firmware could probably be tweaked so to at least keep the RF connection up.
Last question is - how do you get audio into the thing? The prospect of having to disassemble my Tx to add a sound file has always kept this as a low priority project for me.

Would it be possible to take power directly from your switches (which ever you choose) and use that to trigger a sound on the sound board? Essentially wiring the board with power and then input from the different switches to trigger that sound? I'm sorry if I sound ignorant but I am not familiar enough with this to sort through the workings of the TX electronics. Would it be possible to wire the Sound board in place of the speaker and add a speaker to the sound board? Seems like a lot of possible programming would have to take place with the sound board. Like I said I'm just not familiar enough. Guess It's time to learn.

If the board has a "switch mode" (the ones linked to do, as well as an Adafruit Sound Fx board I bought for a non-RC project), then yeah, you should be able to do that. Personally, I'm more interested in replacing the alerts with voices, so I don't have to guess whether a beep was because the one of the batteries was getting low, poor signals strength, or something else.
I think I'm going to write something to play the stuff in sounds.ini on my desktop....

That's what I am also interested in, Voice! It looks to me like the main circuit board in the TX is integrated ( like an integrated mother board for a pc). So the challenge would be locating what generates the different (beeps) for the given input or signal, I.E LOW BATTERY, LOST SIGNAL ECT... and tapping into that. Sending those given signals to the FX board and triggering the proper sound (voice) for the given input?
I had initially thought about the sounds.ini file but speculated that because it works on simple numbers (b1=100)and letters that using an mp3 or similar type file would not be feasible due to the type of code it uses. Again I am not familiar enough to write code to make this work and do not pretend to understand how it works. would be nice to have a Taranis to tear into and see what they are doing and have an extra Devo to experiment with.
