NES Classic Game Console

I saw the Nintendo announced that NES Classic Edition will return to stores on June 29. When it is first launched in November 2016, I think it is a good idea to have one. I can tell my kids, how I like the home game when I am at their age. It is sold out so fast in 2016. It is reported that about 2.3 million NES Classic Editions were sold from November 2016 to April 2017 worldwide. Nintendo announced they were discontinuing the product. I thought I may not have one.


When I traveled to San Francisco, I learned this news. NES Classic will be back on June 29, 2018. At last, I bought one at Walmart Burnaby store.

Let me copy and paste some information from Wikipedia page.

Upgrade my Kindle Paperwhite 7th

There is a new, free software update available for your Kindle Paperwhite (7th Generation). This update automatically downloads and installs on your Kindle Paperwhite when connected wirelessly; however, you can also manually download the software and transfer the update to your device via USB cable.

Of course, I always download the firmware from the official site and transfer the bin file of the new firmware to the root of the Kindle Paperwhite 7th generation.

Before the upgrade, the current version of my Kindle is v5.9.6.1

Upgrade D-Link DIR-880L Firmware

I have my D-Link DIR-880L router for almost one and half years. I flashed the firmware to use DD-WRT one. Later I flashed back to D-Link firmware.

The latest version is 1.08 on D-Link Canadian website. I upgraded it long time ago.

On the D-Link support forum, it shows an updated version of firmware is available for EU users.  I am not sure if they are any difference between Canada edition and EU edition, on the hardware basis.

I believe the USA and Canada may use the same hardware. So I go to USA D-Link website.

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

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 site:

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