Hi guys,

It looks like it's going to take more time than expected to get the new sensors... In the meantime, I though it would be nice to focus a little bit on the mechanics. I got some help from to colleagues, Dan and Lee, and here's what they came up with for the drum module's enclosure:

The next figure shows where the soundcard is located, and how it's secured down. It also shows the junction between the left and right parts of the enclosure, that way everything is stable and there's absolutely no play when the two parts are assembled together.

The next figure shows where the Raspberry Pi is located (green rectangle).

As you can see, there's plenty of space for the soundcard, and it's easily accessible. Lee already got a 3D-printed enclosure similar to that one, and it doesn't look bad at all.

Cheers.
