Fitbit Surge HR review


So today I had to take a stress test and get fitted for a heart rate monitor. It was the first time ever doing these things so I was nervous but also geeked out. When you see all that tech and then they are showing you pictures of your heart before and after exercise it’s pretty cool. Anyway…

People talk about the “accuracy” of all the consumer based HR monitors for exercise. I decided to wear my Surge for all these tests, and sneak a peak at the EKG machines, which are really calibrated.

Resting HR:
FB Surge: 56-60, EKG 58-61
Exercise HR – At 8 min. 10% incline, jogging
FB Surge: 140-154, EKG 151-155

So, while they didnt match up exactly I have to say that I am very impressed with the outcome. The Fitbit Surge is darn accurate, even more amazing as the EKG benifits from all the different direct connections for optimal readouts.

The obvious difference being the EKG is giving realtime where the FitBit Surge changes are a little bit slower. But that is to be expected.

Rest assured, if you are looking to see if the HR monitor of the Surge is accurate know that its close enough for exercise.

Thanks for tuning into another episode of Geek Life with me, Adrian

GORT – The day the earth DID NOT stand still

If you are a Sci-fi fan then you are probably familiar with the lovable Gort from “The Day the Earth Stood Still.”  Well, this post has nothing to do with that Gort. Instead, it has to do with this Gort, a command line tool for RobotOps.

I have been trying to work with CylonJS and various pieces of hardware lately, and I ran across the GORT software on their Arduino page.  It seemed pretty cool, a simple download and unzip and you are ready to rock some device scanning from the command line.  I would say that this tool is pretty useful, and easy to use.  Here are a couple of things I have used it for, as well as a tip.

Install – you download their package and unzip.  Then you have this gort directory sitting wherever it was unzipped to.  I recommend, for Mac, that you copy that folder to /usr/local, then set up your .bashrc or .bash-profile to have a path to it, something like this:

export PATH=/usr/local/bin:/usr/local/gort_0.2.2_darwin_amd64:$PATH

Now you will be able to run the gort command anywhere in your system, which is useful.

The two main things I use it for are to scan for ports ( gort scan serial ) and to upload firmata to an Arduino without using the Aruino IDE.

That’s all I have for you on this topic, so go ahead and check out the site mentioned above and hang with Gort.
