Informal. any microorganism, especially a virus: He was laid up for a week by an intestinal bug. Informal. a defect or imperfection, as in a…

I found a major memory leak in the Linkage program. Fortunately, the leak only added up to large amounts of memory if a simulation was running for a while. The leak was caused by my forgetting to create a virtual destructor for a C++ class. One of the…

I have a new contract job that involves the Windows Phone and I can’t make any changes to the Linkage program for a few months. Since I have some interesting features in the latest version, I wanted to share it. This new version, available here, has some recent…

It took me a while but I now totally understand the DXF format. It wasn’t until I needed to change a bit of the output from the free source code I used, that I needed up getting the details I needed to not be confused. The format is…

The code was fairly simple to write and I had a few minutes to spare today while running some long tests on other code. The video shows a few variations of the multiple slider mechanisms. The sliding connectors must have the exact same sliding radius for these to…

Link That Slides on Curve I am attempting to make a link slide on a curve. When I started writing the code to handle this, I thought that maybe there is a better way. There must be a way to write the simulation code so that there are…

While testing the sliding link feature to make sure that I had not missed something when programming the curved path handling, I have been making interesting mechanisms. Although some configurations are still not handled in the code, things like this work fine. Interesting Mechanism Video

A typo in my post a moment ago made me wonder if I should just add a letter to the word “linkage” and use that as the new name of the program. “Linkjage” has a certain ring to it. Oscillating input is something that I have thought about…

I moved the pink entry to a later position in the color table. Linkage should now have pink links only after there are more than 15 or 20 links in the mechanism. I started to notice that all of the images  that I was posting were a bit…

Curved Sliding Connector Paths are working! There is a type of configuration that is not handled by the simulator but the simpler situations are now handled. Valid Sliding Connector Curved Paths   Invalid Curved Paths   I am planning on improving the simulator so that it can handle…
