It's always fun to go looking at some of the gadgets our Asian
counterparts dream up. Here's a small sample of ones I've come across
recently that elicited a 'that's cool' or a 'that's crazy' reaction:
This novelty is a USB flash memory card with a twist: it has a digital
display built right into it so you can show your photos right off the
card without a computer. Seems a little confused to me - if I wanted a
small player there are other options that use more of the surface area
for the screen. If I wanted a USB memory card I'd go for something more
compact. Still, it's a neat idea and it looks like it could almost fit
in a wallet. \
This HD camera is designed to mount in your car, it looks like it can
record in loop mode, so if you are ever involved in an accident you have
all the proof you need. There's some sample video on YouTube showing it
in action and the video quality is pretty impressive.
It would be a neat device to take along on a driving vacation, or maybe
on one of the more scenic drives around here like Mt. Rainier or the
Olympic peninsula.
If you bought four of them your could make your own Google street view
car!
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 ...
