Activity Watch is an open source time tracker for your computer. It automatically tracks how you spend your time on your computer. It is a modular system. There are different modules to track different things so that you can correlate different activities. For example, some people have created different modules to track and import spotify usage into the tracker. Others have used it to track the height of a height-adjustable table. Each of these modules are called “watchers” since they “watch” something and report it to the Activity Watch server that runs locally and privately.

I wrote a blog post about the basics of Machine learning for SageMotion. It is geared towards biomechanics and biomechanists.

For the Euler angle blog post that was posted recently, I thought that it would be cool to have a way to experience Euler angles more interactively. To this end, I made a little widget with javascript and three.js to animate a cube with Euler angles. It does a pretty good job of explaining the different axes and the difference between body and global rotations. You can find the source code here on github and a more full screen version of it here.

I realized that with onshape I could share direct links to some of my designs. Below are a few special ones:

I recently wrote another blog post for the company that I work for. You can find it here: Why You Should Switch to Python from Matlab.

I realized that I could add links to a few of the blog posts that I wrote for SageMotion. You can find them below:

How does an IMU Work?

What is an Open Algorithm (This was a joint blog by Peter Shull and I)

How Does IMU Sensor Fusion Work?

I’ll try to add more links as I write more posts.
