Network storage and backup

November 28th, 2014 No comments

I lost a HD the other day and whatever data was on it. I think I had most things backued up but there was still some data that is gone forever. This got me thinking about how to better protect ALL devices in my house.

Storage is cheap, but I don’t want 2 HD in every machine. And some machines like the laptops can’t use 2 HDs.

At the same time I need to re-evaluate the NAS solution in my house. I’m currently managing two systems. An UnRaid computer for archival storage and a Nas4Free machine for a faster access of data.

Steps:

1. Add an SSD drive to UnRaid as a cache drive to speed up write functions on the UnRaid system, and compare network read/write speeds with the Nas4Free box. See how different the two really are.

2a. If speeds are very close, take apart the Nas4Free array and move the two 2TB drives to the UnRaid system.

2b. If speeds are not close buy two 2TB drives and replace the two 1TB drives in the UnRaid system. This will increase the array capacity by 2TB.

3. For all computers set up some software that will backup the working files of all computers to a backup folder on the UnRaid system. Have this backup be done once a day (probably at night). A scheduled rsync operation (that also mirrors deleted files) should suffice. I don’t want an ever growing amount of data. Just a mirror copy of the machine’s HD in case it fails.

Splitting up large objects

November 28th, 2014 No comments

To print large objects, they need to be split up into smaller pieces that fit within the 3d printer’s build volume.

Some useful links:

Stratasys page for bonding parts together.

Interesting plugin for SW, Inventor and AutoCad that will split up a large object and break it into smaller build volume sized chunks. Find it HERE.

Blood glucose meter research

November 26th, 2014 No comments

Looking for a blood glucose meter.
Best 10 glucometers as lsorted by Men’s health
http://www.menshealth.com/spotlight/diabetes/top-blood-glucose-meters.php
It looks like not all blood sugar meters are equally accurate. List of a bunch of meters on this page.
http://www.diabetesdaily.com/voices/2013/07/blood-glucose-meter-accuracy-comparison-chart/
Same data sorted by total accuracy from lowest to highest (total accuracy = the sum of all the entries for each unit)
(table at the bottom of post)

Some recommendations for the Accu-Chek Active since it’s accurate and test strips are least expensive.
Excellent article on the technical challenges of getting accurate readings from glucometers:

Variable Pitch Quad rotor cont’d

November 16th, 2014 No comments

The previous post about the align 500 heli tail being useful was not correct. I am looking for a tail shaft of 5mm so I need to move to the 600 size heli.

Variable Pitch Quad rotor cont’d

November 11th, 2014 No comments

I got searching the other night for ideas on bulding a VP quad again.

One of the issues i had last time was finding a decent pitch slider mechanism. Well I found a few reasonably priced:

http://www.flying-hobby.com/500esp-metal-tail-pitch-assembly-p-10400.html

http://www.helipal.com/h50189-500metal-tail-pitch-assembly.html

It seems the align trex500 heli pitch slider p/n is either h50189 or H50190. Should find out what the difference between them is.

Tracking Productivity

October 8th, 2014 No comments

Remembered the tracking that Devine does to measure his in/out productivity.
Thinking about starting my own tracking system soon.

Maybe pay someone to develop the web app for me. I will have to think about how I want it to work.

Day 12

It was quiet last night. No raccoons issues, no loud neighbors, no people staying up late.
Got a good nights sleep again.

The morning was cool and a fire and tea was welcome.IMG_20140808_085854

Day 10 (tuesday)

I had a hard time sleeping last night. I felt like I was awake quote a bit and could not fall asleep many times, though my sleep tracking app showed lots of deep sleep. Loosing faith in that sleep tracking app.

Fire and tea. Again.

It was quiet on the camp ground last night. In our area, there is only one other camp site that is occupied. Three young adults in tents.
