CyberPower UPS

Finally, I decided to invest in a UPS! I decided to put my money down on a UPS to protect my NAS and web server from power outage. Which could happen anytime. I decided to invest in Cyberpowerv model number: CP900EPFCLCD. 

Why now?

I decided to get a UPS after a recent power outage that made my one drive fail on my QNAP NAS. I could not access the drive until it rebuilds the RAID. In my case it was RAID 5. As you might already know, RAID 5 has distributed parity data across the drives you have. In my case, I have 5 3 Terabytes drives, thus parity data is distributed across the 5 of them. When one drive failed, the data is reconstructed from the other drives.

The rebuild could take days depends on the size of the drives. In my case, it took 16 hours, and then it went into optimisation mode which took 2~3 days.

It went into optimisation because some of block data went corrupt.

Why CyberPower?

In any case, I decided to invest in a UPS. I picked CyberPower because the price was right compared to APC. However, the price is one factor, the other is the fact that it has a True Sine Wave inverter inside. It means that once the power is out, the power that comes from the battery is inverted into a power similar to the one that you get from a wall outlet.

Other cheaper UPSs use simulated sine wave  (also called, modified sine wave) which looks squarish in shape. This might cause issues with some of the equipments. In my experience, modified sine wave inverter causes much heat when it runs. It also waste much energy when it runs. So I decided to just get a true sine wave UPS and have a peace of mind.

UPS uses:

It you are planning to run a web server from home, then get a UPS. You need one to prevent your website from going down. It is also true if you are planning to host your own personal cloud storage. I do not plan to plug the monitor to the UPS. It would waste battery power. I will only plug my server and NAS. TV, printers, and my gaming consoles will not be plugged.

Since the server is accessible from remotely, I can just shut it down remotely when I learn that there is a power outage at home.

The other important thing to be aware of is getting another UPS for your home internet connection. You don’t want your computer to stay on without being able to reach it. Especially if you plan to run a server from home.

Unboxing: 

The UPS comes with a USB cable, telephone cable, power cable, and a UPS cable. Plus the Unit itself. I expected the unit to be huge, but to my surprise, it turned out to be small.

Extra cables: 

I decided to invest in extra cables. Since computers and other devices uses regular cables, do yourself a favour and invest in some extra cables. I decided to get extra UPS cables, plus I got many other kinds of cables for devices that I plan to plug into the UPS.

I got the following:

1- C 14 to C7

2- C 14 to C 5

61aVQ7ckWIL._SX522_

3- C 14 to C 13

Overall, I am satisfied with the purchase. The quality is good. It does its job. It has a small LCD that displays current load, how long will it last, and other figures.

Second Experiment with Solar Panels

I like to keep myself busy with projects during my weekends. I also like to use junk that might be useful. This post is about my second experiment with solar panels, but this time I used it with lighting.

Why I decided to work on this project. 

I recently installed a home shade n my front yard so that I can park my car in a cool shady place. Away from the sun. However, this shade blocked the sun rays, and even during the night, it was dark. So i decided to install 4 lights to light up the area under the shade that I installed.

I had two solar panels laying around, each with 100 watts. I decided to connect the panels in series to generate 24v. I decided to go this route because I did my calculations and found out that I would need much less Amr/Hour per battery than a 12V system. With 24v system, a load 60 watts that needs to run for 8 hours would require 46 AH. But for a 12v system with the same requirement would require almost the double ~94. Source

How is the system wired?

I placed the panels just above the shade, so that I gets exposed to the sun most of the day. Then I salvaged two used car batteries that I had laying around being unused for few years. Surprisingly working fine. As long as they are being pushed half of their capacity, they would be fine. I keep the timer and the rest of parts inside a solar box. A sturdy box that is made of plastic. It is able to withstand heat, and would protect the system component from dust or rain.

All is lift was to connect panels to the charge controller, and then the controller to the batteries. The batteries to the timer and the timer to the lights. Light were connected in parallel to avoid interrupting the circuit in case one of the lights got burned.

 

 

How did it go?

Very well. The system worked great for 3 weeks before one of the batteries went bad. It might got over drained. But I was satisfied with what I learned from this project. The fact that I used junk batteries to build this system was cool.

What’s next?

There few videos on YouTube on how to fix dry car batteries. I already looked at them and understood what I need to do in order for me to revive the batteries. I will do that next and update this post with a photo of working lights.

Until then,  farewell.

Panasonic ES7112 Battery Replacement

It is much easier to go out and buy a replacement for anything that breaks down in your house. Especially the small electronics such as shavers.

For me, I have the tendency to tinker with things before I decide to replace them.

This happens to my 6 years old Panasonic shaver. The battery would not hold a charge for more than 10 minutes. I do have to charge it every time I need to use it which is inconvenient.

So I decided to open it up and replace the batteries myself. I started by removing the bottom screws. Fast forward, I managed to remove the shells that cover the inside parts. img_9111-1img_9110-1

 

The batteries that I found were small AA and thus the battery compartment. I had few Energizer rechargeable batteries laying around but they wouldn’t fit inside the battery compartment. So I decided to use AAA batteries that I bought for Ikea. They hold 1000 mili Amps. Much less than the batteries that are inside the shaver, but they will do.

Since I am going to use a smaller batteries, I had to use wires and solder them. Since the batteries  were small, so  I also needed to use double sided tape to stick them inside the battery compartment.

In the end, I reassembled it and it works great and holds the charge for much longer the 6 years old batteries. Also saved myself a trip to the electric store and 50$!

 

Qatar, the Fat Nation.

The trigger I was reading an article on the mail online saying that Qatar is the world’s fattest nation on the world where half of the adult population are obese. After reading this, as usual, I started to think about it, doubt a little and then discuss it with few friends. What do I mean […]

Having a Viarity of people is Wonderful

Why Having Different People Around is Fun.
Just happened to me last week when I was running some personal errands. While I was running these errands, I meet few people that I really liked and appreciated the fact that I am fortunate enough to meet them. They happen to be from different parts of the world.

I am lucky because I live in a multicultural society. You will find unique people from across the world. Which made me say wow. In addition to their look, personality differs too, which is really interesting.

Benefits?

Having the chance to meet people from different parts of the world exposes you to different way of thinking. People who came from different parts of the world bring with them their own culture and thoughts. Interacting with them might expose you to a whole new prospect about of life itself. It might even show you new ways of doing things that you do everyday.

They might try to change how you see the world.

It gives you new prospective on life. Make you appreciate life for its bad and the worst.

The case of people in the Gulf region 
Some people here in the Gulf region dislike the idea of having a multicultural community. People tend to be conserving when adopting change. People from the west for example, think that anything that looks different from how they do it is backward. This pushes local people away from them.

Also people from the Gulf region tend to be superstitious, while people from the western world are less superstitious which causes misunderstanding.

Education and Qatar

Today while looking at the daily newspaper that I read everyday, I found one article that caught my attention. I will attach it here and then translate the jest of it. It says that most of the youth of Qatar prefer not to continue their higher education and prefer to join the work force. I […]

The Funny and Yet Sad Fact About the World

The chances of having something amazing happening to you are rare. In fact rarer than what we all can imagine. Not taking advantage of the chances you get in life could render you life useless to a degree. Missing on the great chances means you’re gonna settle for a lesser valued one and it might not be as close to the missed one. However, you’re just taking it just so that you’re not so late and missing on life.

I want to say whenever you see an opportunity out there, by all means grab it and never let go of it. It could change you’re life for the better. Also be optimistic about it. Take it in a good faith. You never know, something huge might come out of it and change your life for the better.

Even if it didn’t work out, still be proud of yourself as you tried and never settled or caved for hesitation and did what you can do at the moment.
