Here is something I am currently working on. I plan on making the sound board and speaker use the wireless transmitter system I currently use on my servo kit, I will also be adding an amplifier. Thanks to Bcurtis for the sound files.
I am going to try to configure one of my wireless transmitters to fit inside my EE-3 with 4 small external pushbuttons to trigger the sound effects. I am hoping to have a working prototype by the end of this week.
I did the CAD layout of the circuit board. It's around 2 inches by 4 inches. I found a small speaker that should fit the ab plate really nice, I will be ordering that speaker and doing some mod to the prototype so the entire kit will fit under the ab plate. I will post some vids once I have it ready.
Is this something that anyone would be interested in? I have been working on the circuit board design and I am fairly happy with it. the board will be about 3"x3" and have an onboard 2.5W amp and a external plug for an Aker. The prototype I have has about 10 sound clips and there is still a lot of memory space for more (the sound board has 16MB on board storage). I am planning on designing an enclosure since the board is bigger than the one I use for the beacon and servo kit.
