Amazon Marketplace API Discovery

Now that we have established a bit of an eCommerce Amazon marketplace background in the preceding posts, it is time to roll up our sleeves and try to dive into Amazon's automation APIs. I say try, because I originally found it very difficult to discover where to dive. My Google-Fu failed me.

Amazon Marketplace Seller Processes

A vendor wishing to sell products on Amazon needs to successfully execute a number of processes in a consistent manner. Earlier posts provided a high level overview of the generic sales transaction steps from both the buyer and the sellers perspective. We now want to provide a more in-depth look at the routine seller processes.

Running a Marketplace Storefront

Before we go and automate everything, it makes sense to step back and think about what we as a seller really need to do.

Marketplace seller: Amazon vs eBay vs etc...

This post is intended to provide some additional introductory eCommerce information so that the reader has a more complete appreciation of the Amazon selling experience.

There are many flavours of online stores. I will quickly & arbitrarily group them into the following categories:

So you want to sell on Amazon?

Amazon is well known in North America (and several other parts beyond our shores). Everybody understands that Amazon is one of the online places you go to buy things. Amazon also means a very different thing to computer geeks: AWS - Amazon Web Services. AWS is known for being a cloud computing service. Very different from the original online store, not shopping related at all. I mention this now because it will come up later. It should not, but it does. Sigh...

Quench Controller in use - Part 2

We have already revealed that my home brew Quench controller based upon an recycled SEA & SEA TTL Converter functioned just fine. And I used a few dives to fine tune any mechanical tray / arm issues. Back to the battery power world.

To review: my goal was to accomplish at least a whole day of diving before a required battery change.

For me a minimum length dive is 60 minutes. I want a slush fund of at least 15 minutes pre-dive slack time. I like to dive 3 or 4 times a day. So 4 x 90 minutes would be my daily power target.

Quench Controller in use - Part 1

Before I discuss power issues, lets reveal real world operational results: the Quench controller was an infinite improvement. I am chuffed.

I started the first few dives on my liveaboard trip without using my home brew Quench controller ** and as per prior experience I had to manually adjust the power on each strobe by reaching out to both of the strobes ***.

Strobe Quench Controller Power Supply - Part 3

Due to large amounts of laziness, some procrastination and an infinite list of shiny pebble opportunities on my part, I was about to head off to a liveaboard dive vacation with a mostly unknown battery life on my Arduino based Quench controller.

Strobe Quench Controller Power Supply - Part 2

My current challenge was to provide a suitable power supply for my 5 volt Arduino Pro Mini that I was jamming inside a reclaimed SEA & SEA TTL converter. The converter previously used a CR-2 battery which would not provide enough voltage for my Ardunio.

Strobe Quench Controller Power Supply - Part 1

I had gutted a SEA & SEA TTL C converter and was replacing the innards with a home brew Arduino board that would provide a strobe Quench controller. To review: the Quench Controller would allow me to manually control the power output of my strobes (up to 2 sets of 2) from a single control knob on the TTL converter housing.
