This weekend I tried the time lapse mode on my GoPro HD Hero. The
weather wasn't great but the results were fairly impressive. On the 60s
interval mode the video was a little bit jerky but on the 10s mode it
came out really smooth. The battery life was good enough for several
hours of filming but it would have been nice if it was longer.
The other issue was in dealing with the sunset which caused the camera
to completely wash out the bright details.
Apart from these minor issues I'm overall still very impressed with the
GoPro HD Hero in both video mode and time-lapse mode.
My photo collection now has over 150,000 photos taken around the world and close to home. Most recently I've been shooting with a Sony A9. Prior to that most photos were taken with a Canon 5D III
Digital Twin are an online representation of a real world object, a copy of its properties in the digital world and a way to send updated and commands to it. In effect I've been making them for years but now they have a trendy name.
Why automated learning is hard for a smart home. The perils of over-fitting, under-fitting and how the general unpredictable nature of life makes it hard to build a system that learns your behavior.
One way to reduce the volume of sensor data is to remove redundant points. In a system with timestamped data recorded on an irregular interval we can achieve this by removing co-linear points.
Home automation systems need to respond to events in the real world. Sometimes it's an analog value, sometimes it's binary, rarely is it clean and not susceptible to problems. Let's discuss some of the ways to convert these inputs into actions.
Another super useful function for handling sensor data and converting to probabilities is the logistic function 1/(1+e^-x). Using this you can easily map values onto a 0.0-1.0 probability range.
In a home automation system we often want to convert a measurement into a probability. The ATAN curve is one of my favorite curves for this as it's easy to map overything onto a 0.0-1.0 range.
Several years ago we did a major remodel. I did all of the finish electrical myself and supervised all of the rough-in electrical. I also put in all of the electrical system and water in our barn. I have opinions ...
