All our days are interesting, but today was extra special. We sold our first Em2 model in Europe. We tested ice structures in a model and it was a huge success. Here Lily adds dye to a chunk of ice. We began full scale production of the new Emriver Em2. And by far...
Today we completed hardware and software for an electronic flow controller for our redesigned Em2. The little box you see here connects to the Em2’s pump and controls flow in the model. And it automatically runs hydrographs! Teachers and students can run...
We’re wrapping up the pumping part of our redesigned Em2. The new model will use electronics to control a 12-volt pump and send flow rate data to an LCD display (and also to a PC via USB and possibly wireless connections). We’re using an Arduino board as...
Lily and I’ve been kicking around different ways to digitally sense flow for the last week, including making our own little propeller/turbine sensor. Today as we cranked on finishing a proposal we’re working on with NCED and Winona State, I glanced at a...
A big day. Lily hooked up her first electronic circuit, and hacked some microprocessor code. My work was interrupted by exclamations of “YES!” and “COOL!” from the lab. Lab sounds I like to hear. Lily has strong skills in biology, chemistry,...
