1.127 it’s all a blur

(I’m actually writing this on Wednesday afternoon, because I was sure I had done a blog post yesterday. But I hadn’t. I was remembering the blog post of Monday. The days are all alike in Sequesterville.)

In the morning I did 20 minutes of exercise, using a video that one of my neighbors had passed around weeks ago, when fitness classes were canceled here. It was pretty good, 20 minutes had me sweating anyway.

An email went out today from Angela, saying that due to problems people had experienced holding the door to get their meal distribution, they would be sending someone from facilities to every upgraded unit (floors 6-10) to “adjust” the door closer. That would be the hydraulic door closer that I was fiddling with on Saturday, because it pushed too hard. I can well imagine that some of the feebler people might have had trouble holding against it while reaching for their meal box.

I spent a couple of hours getting started on the Crafting Interpreters project. It looks to be quite fun, basically re-doing in Python what the author displays in the book, written in Java. Java’s an ugly language; I’m glad I never had to use it. But now I have to learn something about it, because I have to figure out what he’s doing and reproduce it. Then I can critique his code, heh heh.

In the evening I put in our 6th floor grocery order, via Instacart to be shopped at Molly Stone. Only three others participated. Maybe we don’t need to do it weekly. Anyway I have to say I am pleased with the Instacart web UI. It is quite easy to find products, to know if they are in stock, to put them in my virtual cart, etc. The order is to be shopped and delivered on Thursday. I installed the Instacart app on my phone so I’ll get timely updates from the shopper.

Late in the day, Mary R. offered an old metronome on the bulletin board. “Sound works, light doesn’t.” I wrote back, if a real musician wants it fine, otherwise, I’d like to try fixing it. Later in the day it appeared outside my door. I went and got my tool box and opened it up. I expected to find a circuit board, maybe discrete transistors. Nope: it’s all analog, based on a nice little spinning A/C motor that rotates a conical drive wheel. Adjusting the rate dial on the front moves a driven wheel along the cone to change its speed. The driven wheel has a lever that tightens and releases a little spring, so every revolution a little metal hammer goes whock against the back of the box. The wheel also has a janky little contact that bridges two copper springs to light a little incandescent bulb on the top.

First job after I got it disassembled was to check continuity through the little bulb. I got out my VOM, which Scott gave me last year and… it was dead. I opened it up, it needs a 9V battery. Of course I don’t have one. So I hustled back to Instacart and added a package of 9V batteries to my grocery order!
