The Em2x nears completion.

Last week was eventful, with bad news from NSF on a proposal and an anthropogenic flood event in our lab.  And many good things; we now have quite a waiting list for what we call the Em2x–our new version of the Emriver Em2.

I’ve worked many days straight, just a few photos for now.

Starting from the top, our old-school oscilloscope (I love this thing) which is getting a good workout; Lily gathering data, a prototyping layout, and various components we’re working on for the Em2x’s electronic pump control/data collection system.

I’ve had a lot of help, especially over the weekend as we closed in on hardware and software design, which is based on the open-source Arduino board.  Thanks again to Chris Alix, Chris Krumm.  And also to Henry Chan at .
