Personal Projects & Interests is my sandbox for life outside the office—where spreadsheets, sensors, and code tackle real-world chores and passions. Here you’ll see data models guiding gear buys, DIY automations that make the house (and gate) smarter, endurance training logged like an experiment, and reflections that tie it all together.
[mathjax] Motivation I had to upgrade the Lego table I made when my kids were much smaller. It needed to be higher and include storage options. Since I’m short on time, I used several existing automation tools to both teach my daughter the power of programming and explore our decision space. The goals were to […] read more
Tonight, I just finished Francis Collins’ book “The Language of God” where he lays out the basic facts of genetics and the human genome, denounces Creationism and rejects Intelligent Design theory, rebukes Richard Dawkins, and generally sets a tone for reasonableness between Christians and scientists. This is a lot of disjoint topics, and while he […] read more

Updating every 90 days isn’t too long to correct mistakes and remember purchases, but it also allows for the busy multi-week sprints that life presents us. While we have used every financial management program available, I’ve found the most straightforward and flexible solution is to […] read more

But when […] read more
I, for one, am tired of arguing. I’m tired of trying to defend evangelicalism when its leaders behave indefensibly. Is there a problem with hypocrisy in the modern church? Yes, just as there was in the ancient, medieval and renaissance churches. Fortunately, Christian doctrine and practice accounts for the fact that all of the churches […] read more
Using my Vera Lite and Z-wave home energy monitor I was able to record a week’s worth of electricity consumption at 30 second intervals. I was surprised how hard it was to use the data to do anything, but amazed with how my behavior changed when I knew our household consumption was being tracked. Again, […] read more
I decided to look at my home energy usage. Below are notes on how I’m approaching it. I wish I could get insight from the MIOS graphing plugin, but it is pretty basic and can’t throw out outliers and has terrible zoom capability. I also never figured out how to set the y-axis.
