podcasts/vidcasts are enjoying tremendous growth through itunes podcast directory, youtube channels and similar services. it is now easy to get overwhelmed under the amount of quality content mostly available for free. Some people overconsume a lot of podcast/vidcast/youtube channels/series. I'm one of them. There is just never enough time, so find a few tips to cope with the overload:
The state of the Internet of Things is bleak and it is looking to get a lot worse.
Sure, we are getting more connected devices at home: laptops, tablets, smartphones, fitness trackers... But the applications and services being used are gradually based on more and more sharing with third-party advertisers and aggregators to lock you in their ecosystem to make it more likely you will buy more of their stuff. And these devices only get more powerful with time, more apps, more complexity, more potential for adware, spyware and malware...
The top of line Withings scale smart body analyzer was released in April 2013. However to this day, 8 months later, it is still impossible to extract the CO2 and temperature data through the API or download these as CSV file. Their customer support just keep tossing the issue under the carpet labeled "forwarded to engineering department", meanwhile they are just busy releasing other botched products.
So I had to figure out a way to get MY data, here is how you can get yours using just firefox:
In order to verify my arduino based prototype, by the end of 2011, I decided to use the depth infrared camera from a kinect to verify "visually" that it works.
I am not going to watch 8 hours of someone sleeping, I'll just get a computer to do that, so I learned some basics for "computer vision" in R. Here I am using frame subtracting by importing each greyscale frame from the depth camera and subtracting it to the next frame. This way I can identify changes and how small/large are these changes between each frame. Here is a sample,
ePlease check out the first part of my sleep monitors series first. Back in May 2011, unsatisfied with the "software" solution I developed with the first prototype, I started developing a "hardware" based solution to develop a contactless sleep actigraph monitor.
And that's what I came up with:
Under the mess of wires, there is an arduino controlling: .an annoying buzzer for the alarm
A few years ago, I was looking to improve my sleep. Measuring it would be a start. However I was not satisfied with any sleep monitors on the market.
I needed a non invasive, no "additional daily routine" solution, ready to trade accuracy for maximum convenience. So back in late 2010 I started work on my first prototype, contactless sleep monitor based on actigraphy.
I found the device great to quantify meditation/mindfulness sessions. However the software is really limited, so I started to look around the harddrive for the data.It turns out you can find your emwave results stored in a sqlite database file in My Documents\emWave\emwave.emdb.
This week I received the Withings Smart Body Analyser or WS-50. I already had their original wifi scale so it was able to integrate my previous weight/fat history with the new scale. The WS-50 in addition to weight and body fat measure adds resting heart rate, temperature and CO2 measurements.
