Amazon Basics AA High-Capacity Rechargeable Batteries (4-Pack) Pre-Charged

February 22, 2018
0 Comments

I bought regular Duracell Alkaline battery at Costco. It is AA size. I used it on the clock, radio, remote controller etc. And at the same time, I would like to use the rechargeable battery for other devices. Such as Xbox wireless controller. My son and I play the game very often. The shacking function makes the battery run faster.

So I online ordered the Amazon Basics AA High-Capacity Rechargeable Batteries (4-Pack) Pre-Charged. Look at the prices.

There are two type of packs. One is 4 batteries, $12.99. The other one is 8 batteries, $26.99.

It doesn’t make sense. I can buy two boxes of 4-pack. The total is $12.99×2 = $25.98. It is cheaper thant the 8-pack.

  • Improved low self discharge
  • Improved high recovery type
  • High Capacity
  • Hundreds of Cycles
  • Excellent Over-discharge Performance
  • Made in Japan
  • Pre-Charged using Solar Energy

Some pictures from Amazon.ca site:

When I received the packages, it looks like above. Protected very well.

Replace OBi110 by OBi200

I have a OBi 110 for many years. I used it for my Google Voice and another SIP provider. But last year, the OBi is not working with Google Voice anymore. Even I flashed the firmware. It extended the life a few months.

I have a brand new OBi200. I bought it in June 2017. Cost me  US$47.46 plus tax.

The old OBi110 is much cheaper than before. I paid US$66 in 2012.

Toner Replacement for Samsung ML-1915

I have a laser printer, Samsung ML-1915. I got it about six years ago. Early January, my daughter found the prints are not clear. I checked it and found the toner is almost gone. I need to buy new toners.

First I did the search on the Internet. Checked the Staples and other stores online, it is so expensive. Over $100 each. I kept looking for the replacement.

At the last, I ordered 2pk toners from Toner4U through Amazon.ca. Two toners total $33.85, including tax, free shipping. I ordered on Jan 28. Received on Feb 2.

Amazon CloudFront adds new edge locations in Montreal and Toronto, our first in Canada

We are pleased to announce the launch of our newest edge locations in Toronto and Montreal, our first edge locations in Canada. Adding locations in Canada has been frequently requested by our customers so we are excited to add these two locations to our global network.

These new edge locations help improve performance and availability to end users of your applications and support all Amazon CloudFront features at no additional cost. Pricing for the new edge locations in Canada is the same as that in the US.

We have also added a second edge location in Sao Paolo, Brazil, our third edge location in Brazil.

3-Port HDMI Switch

January 16, 2015

Got this 3Port HDMI Switch on Amazon from the third party seller. Cost $5.97.

3-port-hdmi

It took about one month for shipping from China Mainland.

I tested it with my XBOX, but the screen is blinking and also tried with my Xiaomi Box, failed.

I read the reviews on Amazon. Found the following:

Beware… This thing is not HDCP compliant so, it is unusable with the PS3 and PS4. On my PS4, it kinda works for a few minutes and then the screen starts to blink on and off. On my PS3 there is “snow” in the display and since it is not 1983 anymore….

My Roku and my AppleTv are always on (no off option on those devices) the automatic switching does not work for these devices, so it does not really offer a big plus over unplugging and re-plugging HDMI cables…

I guess it could work to split HDMI in between a PVR and a standard Blu-Ray player, but it is of no use for game consoles and for Roku/AppleTv users.

Go back to Amazon AWS CloudFront

March 12, 2014

I start to use CDN from April 2010, with MaxCDN. Later, I moved to Amazon, FrontCloud in August, 2010.
For some reason, I move back to MaxCDN. I start to use MaxCDN again from June 2012. In April 2013, I started to use CDN77.
A few days ago, in March 2014, I go back to Amazon AWS CloudFront. It is a reliable CDN service provider. The price is pay as you go. Based on my network volume, I prefer this price structure.

I setup CloudFront with custom origin server. Add CNAME on it. One of the CDN rules is to use two CDN host name, not one, not three. Two is the perfect number and best performance.

I tested my new CloudFront CDN ping value through CA ping tool. There are over 30 monitoring stations worldwide. My testing result is:

  • AWS CloudFront CDN,

Average: 48.29
Median: 3.05

  • CDN77 CDN

Average: 51.69
Median: 20.15

It shows that CloudFront has better ping value.
