In my last post on audio recording latency, I was left with a bit of a mystery. My loopback test had an uncompensated latency of 20 ms that I couldn't explain. I paused and came back to the problem with fresh ears. Since I knew I'd
Over the past year, I've been making a concerted effort to learn more about digital audio production and explore some new musical horizons. It's been a steep learning curve, but I've enjoyed being a novice again. As with any endeavor to learn, the path
During my first post on motion-activated lighting, I showed how a PSIR sensor paired with some LED strips can make for very nice lighting that turns on and off without any intervention. Here, I'll describe how integrating these devices with a home automation orchestrator can make them complement
Background My 3D printing hobby started during residency. The work I did for this (see our unpublished paper) occurred around 2013-2014. At the time, 3D printing was becoming very popular, and many institutions were looking for novel ways to apply it in medicine. Once that project concluded and I gave
When I first installed our Theater LED Lighting, I set it to mostly default to a rainbow effect available on the ESPHome. It gives a pleasing effect that looks like this. This is described by the following relationship: \[ h=\frac{n}{N} + \frac{t}{P} \% 1 \] where \( h \) is the
The last couple of posts described adding recessed lighting to our home. In this effort, I'll use a custom PCB as well as a 3D printed enclosure to make recessed lighting for the bathroom. Anyone who's stubbed their toe trying to fumble to the bathroom in
In my last post, I described a new circuit board to add IR motion detection to our kitchen to control some recessed lights. The IR motion sensors are compact little components, but they need to be mounted permanently. Over the past few days, I designed and fabricated a mount for
One of the improvements to our new home has been to replace recessed lighting. In our home theater, there is a recessed area in the ceiling that had some old tube lights. We replaced those with WS2811 strips controlled by an Electrodragon controller. This looked great. Next, we replaced the
A few years ago, Trang gave me a Samsung Gear S3 watch. It's been great, but I'm not a watch person, so I really only use it for exercise. Lately, the battery has been failing. I couldn't run for more than about 20 minutes
Brewing Since I'm resurrecting the brewery for a Halloween one off, I thought the title appropriate. I haven't brewed anything for years. With two kids, another project taking priority, and my brewery in shambles, it hasn't been in the cards. However, one of Trang&
3D Printing We decided to start work on the Halloween costumes early this year because we have an ambitious goal. We'll need the extra time if we're going to get there! We plan to do a Halloween video, so that'll be up when the
