So it’s been about 90 degrees in Brockport, and we have had to resort to closing up the house and turning on the AC. I don’t like setting the thermostat too low, and keep it between 74 and 76; however this is apparently too cold for Gimli:

It’s bath time at the grotto
It looks like the robin and grackle young have fledged. Today there is a marked uptick in bathing activity at the grotto. This youngster (a starling) has been dancing around the waterfall trying to find a spot where it can mimic the older birds. Robins and mature grackles dominate the two ideal bathing spots. The shaky, poor color video is due to me filming this with my SLR through the window.
Creatures of the Grotto
Earlier this summer, I built a waterfall for my garden pond. Almost immediately, it became a traffic hub for a variety of birds (and even a few mammals) in the neighborhood. Here are a few of the critters we’ve been able to photograph.
The start of FeAtHEr-Cm
Today I did some electrochemistry.
OK, that’s not too surprising from a person who earned is PhD doing electrochemistry; however this is different, and it has nothing to do with me avoiding cyclic voltammetry for the last decade of my career. It’s because I built this:
That’s a bare-bones potentiostat built on top of the Adafruit Feather M4 Express and programmed using Circuitpython. There remains a lot of work to be done, but the fact that I could build a functioning scientific instrument for under $30 makes me think that this approach could make it possible one day to have a 1:1 student-to-instrument ratio when teaching voltammetry in analytical chemistry courses.
I’m thinking that it may be possible to build an entire suite of chemistry instrumentation based on the Feather platform, so I’m coining the phrase FeAtHEr-Cm for this project.
One year older
Today I’m silver years old, as informed to me by my periodic table.
