Aliexpress: Day 10 (CZ329)


Flight Plan CZ329
Day 10

The day was almost over, when to my surprise, I refreshed the tracking information and .... we have a flight number! Two of the orders now have a reference to CZ329, and when I put that into a flight search website it comes up with:

It seems possible that the first two orders may have arrived in the country now. Now that I have a rough timeline from the first two orders, I have placed another order with the same store to see if there is any consistency. I have also now spent over fifty dollars in the first ten days.

WTH!!: Video production on a desktop



What the      H   E   DOUBLE HOCKEY STICKS!!!

History

In the Week in Review (Week 15) some observant people will notice item #3 where I described writing a quick tool for making custom thumbnails and my desire to post both code and video online for all to see. It is now four days later and I still have not been able to produce a video worth uploading to the interweb. I did not expect to be unable to produce a "simple" video with the tools that are available. I already have a 9 minute timelapse video of myself programming.

Structure of a "simple" video

My thoughts on what is required of a video before I would upload it to YouTube etc, is pretty basic.

  1. The video needs a brief, 5 second, picture at the start with the website address on it.
  2. Speed up the timelapse video so it is only 4 minutes 45 seconds long.
  3. The ending picture, which:
    1. display "Thank you for watching"
    2. again display website url
Thoughts on Audio

You might notice that I have nothing in that list about sound. That is because this video would have no audio attached. You would not hear me narrating, nor the rapid clicks of the keyboard. I do not believe there is even any need for music. Though I did briefly ponder setting the whole video to the music played during Benny Hill's chase scenes
I do not feel the need to waste other peoples internet bandwidth.
The only thing adding audio to this video would do is waste the bandwidth of those who actually watch it. Even though I do not live in a country where I need to be concerned about the bandwidth I use. And it would be quite presumptuous of me to think that there will be enough people watching my videos to make bandwidth a concern.

My First? Mistake

Without thinking, and because I was merely playing with the concept of creating my own thumbnail creation software/tool, the timelapse video is 1280px   X   1024px resolution. I would have saved a lot of time if I had decided to capture the timelapse on my main desktop. Most people now, to my understanding, have 16:9 aspect ratio either 720p or 1080p monitors and tvs. The timelapse video is almost perfectly square.

Wondershare's Filmora

The Positives
  • filmora does allow you to very easily drag and drop elements of your video onto the time line and move them around.
  • Easily able to preview your changes
The Negatives
  • Not enough control over your video's resolutions
  • Does not allow you to overlay one video onto another
  • Only preset positions and sizes for video in video
Lightworks (free version)

The Positives
  • Incredibly options
  • Able to segment off your editing into different rooms
  • Fully production ready
The Negatives
  • You have to make sure the video you are importing is the same frame rate as the final video will be!!!
  • Only exports 1080p directly to Vimeo, and only if you give them access
  • Only 720p if your exporting to YouTube
  • have to have internet access when you start program to use it
  • Huge learning curve
You can solve a lot of the negative issues I had with this software ... for a fee. The cost of which is hard pressed to explain to your significant other just so you can upload a mediocre video. 
  • $24.99 a month
  • or $174.99 a year
  • or $437.99 outright

Conclusion

Unfortunately I am going to post this before I have a solid statement to rap this post up with. Though there is a idea bouncing around in my head which will probably be the content for another post.

Aliexpress: Day 9 (Almost getting the hang of it)


Almost getting the hang of it
Day 9

There are a lot of differences between what Aliexpress tells you about the tracking information, and what different tracking websites display. It is taking much longer to figure out all the co-relations. I probably will not be able to fully explain, and know, which parts line up until after some of the orders start to arrive.

I ordered a single item today. I am thinking that I will move from ordering something everyday, to only ordering items during the work week. I have noticed that the costs can add up quickly:

ie: 1 order a day * 30 days * average cost of order = 30 * average order cost

Or at the rate I'm going approximately $125.00, and I have several larger orders I was planning on placing later on in the process. After running some quick numbers I could possibly spend over $200 in less then 30 days. This could quickly become an expensive "hobby...?"

Aliexpress: Day 8 (1 for me, 1 for her)


1 for Me, 1 for Her
Day 8

Found something I think my significant other will find useful (possibly), but definitely humorous so I had to order it. Oddly enough both products were ordered from stores with the word "Beauty" in their name. Normally I would not find that too odd, but neither item has even a remote inkling to do with fashion.

I have also spent a lot of time today trying to document, organize, and relate the information I get from the tracking software with what the Aliexpress application is telling me. That information will be for a post another day.

ESP8266: An introduction to the family



The ESP8266
The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack andmicrocontroller capability produced by Shanghai-based Chinese manufacturer, Espressif.
Wikipedia


Core Features
  • Processor
    Tensilica Xtensa LX106 running at 80 MHz (32-bit RISC)
  • Memory
    Code Memory:   64 KiB
    Data Memory:    96 Kib
  • Storage
    External QSPI flash
  • WIFI
    802.11 b/g/n WEP or WPA/WPA2
  • GPIO
    16 pins
    1 10-bit ADC
  • Interfaces
    SPII²C
    I²S interfaces with DMA

The Family
Starting in 2014 several modules based on the ESP8266 chip have been produced. Initially most of the modules were developed by AI-Thinker. With its low cost, there have been an abundance of manufactures creating modules which loosely follow several patterns.

AI-Thinker has produced at least 14 different modules based on the ESP8266 to date. With there being at least 15 other modules produced by the likes of Adafruit, SparkFun, ESPert, and NodeMcu.

Which Module Do I Need?
  1. Do you need GPIO?
    1. NO
      • ESP-05
    2. YES - Do you need built in USB-To-Serial?
      1. YES
        • NodeMcu
      2. NO - Are you going to use a breadboard?
        1. YES
          • ESP-201
        2. NO - Do yo need more then 2 GPIO pins?
          1. YES
            • ESP-12
            • Testboard
          2. NO
            • ESP-01
If you need FCC approved equipment your only real choices seem to be the ESP-12 & NodeMcu modules.

Aliexpress: Day 7 (1 Ordered, 1 Paid, 1 Shipped)



1 Ordered, 1 Paid, 1 Shipped
Day 7

The day started out with me receiving a email saying another of my orders has been shipped. Making my orders up to date.

Then I realized according to Aliexpress there is actually more then one stage from being sent to being received. It would appear that receiving an "order is shipped" email just means that the store has processed your order, but your order has not left the warehouse. Aliexpress does not consider the date your item is shipped until your package has been picked up from the warehouse.

After realizing the "Order is shipped" email was not the one to be most interested in, I combed through my current orders to realize that as of today there has only been three of my orders actually shipped. The orders that have been shipped are orders #1,2,3,4, and 8.

Julian Ilett: Postbag Summary (1-10)


Julian Ilett

What can I say about a man I have never met: Actually quite a lot seeing as that man is Julian Ilett, and he has uploaded a considerable number of videos to YouTube.  Instead of my ramblings though, I am going to leave you with a brief excerpt of how he describes himself on YouTube.

I buy the cheapest electronic modules and components I can find, direct from China, and try to do interesting and useful things with them.  Currently playing with: ESP8266 WiFi modules, Arduino microcontrollers, nRF24L01+ wireless data transceivers, OLED LCD LED displays and sensors... 
Absolutely won't touch: Unbranded cheap mains powered devices.

Week in Review (Week 15)


Monday April 11, 2016 - Sunday April 17, 2016

According to ISO-8601 standard, weeks start on Monday. The first week of each year is the week which contains that year's first Thursday. This oddly gives the capability for the year to have 53 weeks instead of the school taught 52.

Week 16's Hardware Review

Here I am going to try to document all "projects" that I have started, continued, or ended in the previous week.

1. DigiStump and DigiSpark. After examining the ATTiny86 micro lines, and stumbling upon the DigiStump family of products, it has peaked my interest in experimenting with their DigiSpark products.

2. Aliexpress, the retail side of Alibaba: Watching several YouTube electronics videos, I noticed how a lot of the people referred to purchasing cheap Chinese reproductions. After looking into it further I noticed a considerable number of them were making their purchases either from eBay or from Aliexpress.
Briefly researching Aliexpress I noticed there are a lot of people wondering if Aliexpress is a scam, or can be trusted. So I started a project to document my experiences with Aliexpress.
3. Thumbnail Creator: Wanting to have custom images for each of my Aliexpress experiences I decided to quickly program (and I use this term loosely) a simple tool to help automate the process. Using GitHub's Electron, and a little bit of javascript, the basics of a simple tool has emerged.
Over the next week I hope to have edited the time lapse video, and upload the code to GitHub.

4. Flipboard. I was pleasantly surprised to find that somebody had featured one of my posts, and this drove plenty of new traffic from the Flipboard application. I now have a new way to consume tech news on the go.
