While working on two multicopter drone related projects, I was distracted by the idea of an ultra endurance drone build, inspired by this discussion. There are really three steps to drone efficiency/endurance 1) keeping everything as light as possible 2) using high efficiency power regulators, motor controllers, and motors 3) highly efficient propellers (which is

As you probably have seen, we athletes are always trying to find the little things that can help us get that little bit of extra speed. One of the challenges we face is heat, with our bodies trying to get rid of all the heat it is generating, all while the sun is beating down

I have been racing bikes since my early teens. Cycling is a really fun sport, but having suffered no less than three concussions crashing in criterium racing, and also having been hit twice by cars while training, I have moved away from the sport a bit. I tried triathlons, but don’t like swimming enough to

For several years I have had a To-Do list item to improve my server monitoring setup. The value is to have a quick and easy way to make sure everything appears to be going well inside the network: unexplained spikes in cpu or network usage might suggest that the network has been compromised. It’s also

For the birdnetpi I have setup at home, there’s been a desire for a good microphone that can sit outside and pick up a wide recording of the general soundscape, in particular of the birds singing. So far, I’ve tried a bunch of different microphones and all have worked. Note that this is after turning

The UCI – the international cycling union, publishes a list of bike frames allowed in the World Tour – the series of races that comprise the premier event of professional road cycling. If there’s a premium mass market road bike, it’s on the list. And this list is a great way to analyze the development

Just as we were beginning to lose all hope – our WiFi at the farm was powered by a daisy-chained rig to Verizon 4G, and there were no other options, we suddenly get Fiber Optic connection in!!?! From best to worst, literally over the course of this morning. Furthermore, I happen to be at the

In the cycling world, there is a wealth of data analysis and visualization tools, of which I have experience with Strava and TrainingPeaks. In fact, cycling is probably one of the most data-mature consumer industries, ironic considering at face value cycling brings up images of rugged mountain trails not computers and sensors. The data we

For all three people in the world who are really interested (myself and my parents), the Catlin farm’s newly-established weather/sensor database is difficult to understand just by glancing at the 40 columns of numbers. So I made a dashboard in which to look at, in particular, the trifecta of agriculture: rain, temp, and sun for
