I’m anticipating some meals with interesting ingredient combinations: we’re running the freezer down before a trip next week. Cue the song, “Lime Jell-O Marshmallow Cottage Cheese Surprise.”

View From Space
Spent the morning mapping and logging issues for each of eight irrigation zones on a rooftop deck on our building. Used a Google Maps satellite image that shows every garden bed and planter.
Time of Flight
I love the name of this device: Time-of-Flight sensor. It measures distance by bouncing a laser beam off a surface. Today I started figuring out how to use it to measure water depth in a tank for our indoor garden. As always, software is the challenge. I’ve previously used ultrasound for this application, but stray…… Continue reading Time of Flight
A Time To Resist
On a day when women lost a Culture Wars battle, and it was clear people like Dwight and me would be the next target, met lovely people, straight and LGBTQ+, at a Pride gathering in our community room.
Mystical Journey
I sometimes point my bike through this yard where sculptors work. I like the accidental sunlight flare on the lens creating a mystical water effect at the bottom. Continued my ride while imagining interpretations of the sculpture, not knowing if it was unfinished.

As the tumor marker graph (below) shows, it’s working, at least for now: it’s pointing towards zero, which is a good thing. I don’t…… Continue reading Pills and Hot Flashes
River Ride
At the start of our cycle ride, looked across Ft. Snelling State Park towards the airport. Followed the Minnesota River, then Mississippi to downtown St. Paul. Cycled back, mainly on trails on the opposite bank. Click through for an extra photo of a (potentially) high voltage eagles’ nest.
Stale Bread/Magic Ingredient
On the kitchen counter: stale bread we’d been collecting in the freezer. Tonight, one of my favorite salads: Italian bread salad.

Continuously Variable LEGO Pneumatic Control
In previous LEGO robotic arm builds I’ve used servo motors to move each joint in the arm. However, the weight of the motor and related mechanism meant each arm needed to be reinforced to the point it became too bulky and exhibited excessive inertia. By contrast, pneumatic cylinders are light, and can apply significant force…… Continue reading Continuously Variable LEGO Pneumatic Control
