    Laser Etcher

    My wife got me a laser etcher. I have been playing around with it, but was having trouble with positioning the start of the etching. Finally figured that out. Looking forward to work with etching.

    Napoleon

    I am currently reading Napoleon by Andrew Roberts. He has a lot of detail on the battles, but the maps in the book are not very helpful to me to understand what happened. I found a YouTube channel that does a good job of illustrating the battles (https://www.youtube.com/@EpichistoryTv). If I watch the videos in conjunction…

    Last Pepper Harvest 2024

    Prepped the pepper bed for winter. Poblanos, jalapeños, and datils, with one zulu. The zulus, a black sweet pepper, were interesting, but the flesh was rather thin and the peppers were pretty small. Next year will plant the other peppers but not the zulus. Will try to find another sweet pepper that does well in…

    Raspberry Pi AI Kit

    Mount Washington

    I found this blog interesting. As a kid, we hiked Mount Washington every summer, though we hiked up Tuckerman’s Ravine. Looking forward to hiking up with my grandchildren when they are ready.

    Using AI To Analyze Books

    I asked my son, an excellent writer, for his comments on my blog post “The Comfort Crisis” (https://deangelis.tech/2024/04/15/the-comfort-crisis/), which used AI and my notes and highlights to analyze the book. Our conversation helped clarify my thinking, but raised more questions. My initial concern was that I might be doing the book’s author a disservice by…

    The Comfort Crisis

    To generate the following analysis of The Comfort Crisis by Michael Easter, I read the book on Kindle and highlighted passages and took notes. I read the notes and highlights a short time later. Then I fed these to ChatGPT with a prompt that asked for an analysis that emphasized my highlights and notes. The…

    Wooden Bowl

    I am working on carving a wooden bowl out of a piece of maple with an angle grinder. This is the first time carving, and really the first time using an angle grinder. I did not know that there were grinding and sanding discs for the grinder, and it has been interesting experimenting with them.…
