How much science is too much?

How much science is too much?

We’re working on a long list for the Em4 model that now includes problems of color and chroma (relative brightness). Another branch of science to explore. Here’s a possible media combination, and the technology involves color and human perception. We want...

Beautiful spring Sunday, with two kinds of worms.

Beautiful spring Sunday, with two kinds of worms.

I went into work early and finished testing our valve and metering array for the Em4. It’s working, and at least conceptually finished. We may have figured out our media color scheme as well, we’ll see. Here’s the ugliest combination for fun. Spring...

Earthquake video fun, Em4 testing.

Earthquake video fun, Em4 testing.

Don’t miss this video of a weather broadcast from Evansville, Indiana at around 4:30am last Friday, as an earthquake occurred. Weather cameras mounted on towers and tall buildings turn out to be good seismometers. Evansville’s about 40 miles from the...

It all started with the arugula.

Kate wanted to go out for dinner last night but I insisted on making a specialty of mine, wood smoked pizza on the grill. Somewhere in there I froze three beers, and what I thought was spinach was arugula (photo). This evil weed did not make it onto the pizza, but I...

An Emriver out, Em4 design/build, more spring.

An Emriver out, Em4 design/build, more spring.

Jessie and I cranked on Em4 pump testing, electronics, flow measurement, and the dye injection system. We are getting some hard lessons in hydraulics. The piped and centrifugal pump version has important differences from the open-channel kind I know well. Today it was...
