This year I decided to revisit the dot-matrix Lego printer that I first built and programmed in 2017. The original design was the result of a lot of iterating, but it still had some significant problems. I wanted to try again, with a focus on eliminating errors and printing very consistent images.
You can download .LXF and .IO models of v3.0 of my LEGO printer, plus Python code for the printer, from the Viper Bots’ GitHub repo.
We were surprised and pleased to learn that the Ferguson Swim Team had arranged to dedicate a tree in Jadzia’s memory at January-Wabash Park. Earlier this summer, they also made a team T-shirt to honor her.
This morning, the Parks and Recreation Department held a short dedication ceremony for three families’ trees at the Ferguson Community Center. Afterward we went with Jadzia’s friends Jossie and Kai to see the tree at January-Wabash. It’s positioned on the hill overlooking the water slide at the pool, not far from where Yoli and I liked to sit with Jadzia when we watched home swim meets. Keep reading to see a short video.
We poured hot water onto the violets, and immediately the water began changing to blue.
This is the final lemonade.
Ludi tells the story:
One of my favorite creations I’ve made so far this year was Violet Lemonade. I first saw it when one of my friends posted about it on social media. It looked really cool and we had all the materials to make it.
To start, I picked enough violets to fill a mason jar. Later I made a violet syrup. Once I mixed the syrup into a pitcher of lemon water, the color changed and it was a pretty purple.
It tasted very good, just like normal lemonade with a hint of… I don’t quite know how to describe it. I almost want to say it had a hint of watery ground pepper.
It was very good, very pretty, and very time-consuming but overall it was very fun to make.
