This is another special case. It seems like the sliding connectors have many special cases. I thought that there were three but now, with this one, there are four. The good news is that I have the two more normal cases working. They are the cases where there…
Continue readingI did some work on the linkage simulator last night. I think I’ve narrowed down the sliding connector issue in the linkage program. There are essentially three situations I need to handle. Consider these images: Figure 1. In figure 1, A and E are fixed. F will be…
Continue readingI am making progress with the linkage simulator. I now have a guess as to how to write the code for the sliding connectors. Waiting a while before trying to write code sometimes lets it work itself out in the back of my head somehow. The boat didn’t…
Continue readingWe tested the boat yesterday. It smokes a little bit and leaks a little but seems seaworthy. We’re heading to the boat-in campground tonight. I need to pull the breaker on the bilge-pump so it doesn’t pump all night and run down the battery. I have jumper cables…
Continue readingThe new hoses for the hydraulic trim on the boat just arrived. Too bad we’ve decided not to keep it (the boat). We’ll have it for a month but once it’s time to store it for winter, we’re going to either sell it or pass it along to…
Continue readingAs expected, I have tired of blog writing after a few days. More importantly, I’ve run out of things to write. So much for “blog therapy.” The boat outdrive trim hydraulics uses motor oil, as far as I can tell and from what my brother tells me. That’s…
Continue readingA title of “Nothing to Write” is an oxymoron or some such thing. The simple act of writing that title means that there was something to write. I rebuilt the trailer brake master cylinder. That involved replacing the replaceable parts in it. it took about 15 minutes and…
Continue readingI ordered hydraulic hoses for the outdrive trim. There are four of them and two looked ok. Still, they are old and who knows what might happen. Hoses are available at a variety of prices. Some websites seem to double the price of everything hoping you won’t shop…
Continue readingI wrote a small PHP script last night to do image processing. I was surprised that it works. I needed to accept a file name, rotation angle, and color. The script opens the PNG file, enlarges it a few pixels to ensure that the rotation doesn’t cause edge…

The program usually runs a few minutes with optimizations, etc…,…
