I didn’t like the picture of the rolling ball sculpture, so I “Photoshopped” it. I removed the power cord form the picture. Here’s the finished sculpture, with mechanical lifting levers/arms, after a bit of work on the image. It’s not the best work I could do, but I…
Continue readingThe latest version of Linkage 2 is available here. New or Different The arrow keys will now step the simulation forwards and backwards. The old [ and ] keys still work. Holding the shift key while pressing a left or right arrow will step the simulation 10 steps…
Continue readingI discovered that my code was using the screen zoom in one of the DXF export calculations, and that the math used to guess at a good connector radius was not quite right. After fixing those two issues, I also made a change to improve the solid link…
Continue readingI need to name these things somehow. I’ve been using the colors to name them, but this one is a sort of muddled blackened steel. This post contains a video of the finished sculpture as well as some historical photos and commentary on the construction of this RBS….
Continue readingThe ball lifter now has a track to go with it: The track screws onto the ball lifter mechanism frame. It can all be disassembled if maintenance is needed on the mechanism. A little oil is all that the mechanism might ever need, but building this as a…
Continue readingThe Linkage program is showing a really weird bug. Bug In the picture, it is obvious that the dotted line that is the arc between two connectors A & C, is not passing through the sliding connector D. This gets worse with time until the triangle shaped link…
Continue readingI love computer games. I try to deny it, but I love them. In a computer game, you can do things that are impossible in real life or even in any non-computer game. In a computer game, you can build an empire, kill lots of bad guys, explore…
Continue readingThe above image is part of a patent. I found this while searching for kinetic sculpture images. It never occurred to me that a person could patent a kinetic sculpture, or any art for that matter. I wonder if my ball lifting mechanism (below) could be patented. I…
Continue readingUPDATE December 30, 2015: I made a new and improved version of the progress ring control. The code is not shown below – that is older code – but you can get a complete Visual Studio project by downloading this zip file: http://www.rectorsquid.com/CircleprogressRing.zip Here’s a picture of the…
Continue readingI don’t often write about computer games, but two iPad games that I recently player seemed outstanding to me. DEVICE 6 by Simogo This was one of the most unusual games that I’ve ever played. The “game” consists of a small number of puzzles wrapped up in an…
