It's a much better match for the amplifier board, and the enclosure should also add some necessary acoustical space for better volume and sound (which I would have had to add as part of the enclosure design with the other speaker). In order to connect this, I got some 90-degree JST connector which I'll try to fit on the amplifier board - so that the speaker can be easily connected (or disconnected for repairs or replacement). I still need to to additional testing for the camera and lighting setup in order to decide which of the two Raspberry Pi camera modules - the normal or the 'NoIR'-one - is better for this application. I also plan to test if the basic imaging results can be improved by using additional LED lighting or not (since normal, low power LEDs don't reach as far as a camera flash or a high power LED).
For the tests, I want to compare the results without additional lighting with the results using the Bright Pi board from Pi-Supply as well as the results using the.
