Took a huge step in buying a new car. Mentally I purchased it, but getting preapproved for a car loan sure did edge me closer to buying a car.
Was surprised how easy it was, all over the phone.
Today was my daughters’ final Cross Country Banquet. A fellow parent and friend said it was bittersweet. It sure was.
Finally made the decision to purchase a car.
Didn’t buy it literally, but purchased it mentally.
I am pretty sure I can make it fit in to our finances, been so busy lately though, havent seriously looked at it.
It works, and it works well.
I got it sensing itag info and recording it to a graph via RRD.
I don’t have a complete Bill of Materials but so far it is about $40 and that includes power supply, SD card, clock and case.
I have two set up so far, I think they are going to work well.
Had an maker meetup today, had a new guy there that has a shop in Renton that does 3D printing and other similar projects.
He sounded pretty darn successful.
Hopefully he cant be a cool resource to build stuff in the future.
Here is a screen shot of the chart
It works but I have to add the rrd data as a batch file. I am pretty sure I can figure out how to add it via python instead of some weird bash script.
I was able to add python rrd modules using a simple
apt-get install python3-rrdtool
In centos did
yum install -y python-devel python3-devel rrdtool-devel gcc
Then pip3 –proxy http://proxy:8080 install rrdtool
Looks like I need to find a way to only scan and log specific mac addresses.
Saw I am collecting all this raw bluetooth data, but it is hard to figure out what is going on by just looking at the lines. I need a graph to make sense of things.
Looking at converting csv data in to rrd, then from rrd into a graph.
Hopefully I can get it done tomorrow.
Wow its been a while since I was on the treadmill for 30 minutes.
Workout was good but I am out of shape.
Will need to keep at it, hoping to get my mile to 15 minutes before end of year.
Data collection totally works, and in a manner I like.
Each device writes to a file with a power and time stamp.
Now I need to graph the results are at least parse the info some how to show when the data was last shown.
Got some tags in the mail today, at least they are different colors.
Got the BLE scanner working.
Have it on the a dev/prod system.
Also found a way for a clean headless install on a Raspberry Pi Zero.
Sucks, have to go in to the office to work today.
Bringing a system up online.
Tired, didn’t have a good sleep. Going to feel it tomorrow.
