I’ve heard from a few people that they’ve tried making purchases from my new online store, but haven’t been able to complete checkout. A couple of people have reported that they couldn’t checkout, then tried again later and it worked – even though I hadn’t changed anything.
My theory is that the problem is with the Australia Post shipping calculation plugin that I’m using with WooCommerce. When you get to the part of the checkout where you enter your address, it uses the size and weight of your order to look up the shipping cost with Australia Post before you can complete the checkout. For some people this doesn’t seem to work, so it just sits there and goes nowhere.
Obviously this is really frustrating and I’d like to make sure it’s fixed, so if you have any problems with the online store please email me at email@example.com. Having more information about exactly when the problem shows up would be a big help.
I’ve checked that all the products have weights and dimensions specified, but perhaps it has problems with some countries or specific destinations.
I finally, FINALLY, got around to putting the parts for my home automation light switches up on the new SuperHouse online store. I thought it would be easy: just put up four products, with 1, 2, 3, or 4 buttons. But then I realised that Australian wall plates don’t suit many people, so I have to make them available as kits to fit into different types of wall plates. Then I realised that people may want different colour buttons, so I have to separate the breakouts from the buttons.
I’m in China visiting electronics parts suppliers and factories as part of the HardworX Shenzhen Innovation Tour, but today I left the famous Huaqiangbei electronics markets to spend some time at Maker Faire Shenzhen, the second largest Maker Faire in the world. This video shows a few of the makers exhibiting their projects. The faire itself stretches across a huge area and uses many buildings, and the basketball courts shown in this video are just one tiny corner of the event.
I’ve now arrived in Shenzhen, China, which is the electronics capital of the world. I’m busy recording video and taking photos so that I can show everyone what it’s like here in the most high-tech city in the world.
This was the view from my hotel room window when I arrived last night:

The octagonal building you can see to the left that disappears above the top of the photo is SEG Plaza, the heart and soul of the electronics industry here. Every other commercial building you can see in that photo (and going out many blocks in every direction) is directly related to electronics manufacturing. There are entire buildings full of nothing but LED vendors. Buildings for case manufacturers. Buildings for cell phone parts. Buildings for LCD panels, both bare (OEM) and retail ready, and every stage in between.
If you’re interested in electronics and you haven’t heard of Shenzhen or the Huaqiangbei markets before, the next few videos that I upload will be eye-opening.
For many years now my friend Karl von Moller has been interviewing people within the Australian electronics industry to build a picture of the state of the industry, and to report on where it’s going.
The latest chapter is now up on YouTube. It features many local engineers and Makers, including myself, so you can see what I looked like when I briefly had the start of a beard! Karl will be travelling to Shenzhen, China with me at the end of next week, and this episode is a prelude to what will be reported back after that trip. The video thumbnail is actually me watching my DIY pick-and-place machine populating an ESP-8266 based PCB, and much of the background footage (including footage of Angus from Espressif working on that same board) was recorded in my lab.
I’m finally taking the step of adding an online store to the SuperHouse site to make it easier to share parts for my projects. I often have people ask where they can buy boards I’ve designed for the projects in SuperHouse, so now I’ll be able to list them for sale.
My home automation light switches have gone through a series of versions, starting with very complicated switches that all had Ethernet built in. Over time I’ve simplified the system so now the light switches themselves are electrically very simple: they’re just illuminated buttons on a breakout board with an RJ45 connector, and absolutely nothing else in them.
The switches connect to a pair of centralised light switch controllers over Cat-5 cable, so that it can detect when the buttons have been pressed and report events to MQTT.
In this episode I show some of the previous versions of my light switches, and then show how I built an Arduino based light switch controller.
There’s also a general introduction to the I/O breakout schema that I use at I/O Breakout. I’ll probably cover this in detail in a future episode because the same breakout shield will be used in other projects.
The light switches themselves are just illuminated buttons on a breakout board, mounted on a standard wall plate. The 4-button panel uses all 4 available data lines. The 3 and 2 button panels simply use fewer data lines. Click on the schematic for a larger version:
I didn’t spend much time in this episode explaining the current version of my light switches because I’m going to cover it in much more detail in the future. This episode is mostly about the controller.
