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’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.
After years of using cheap lino cutting mats from the $2 shop, I’ve finally put proper ESD mat down on my electronics benches.
I wanted to use a nice blue mat, but Dave Jones (@eevblog) had a bad experience with discoloration so I decided to try plain grey instead. Hopefully this won’t end up going a strange green colour like Dave’s.
I got the mat from Oritech in Sydney. Their full range is listed here:
The last few months have been an emotional roller coaster as my wife and I complete the sale of a business that I began in a spare room at my mother’s house more than 20 years ago. This hasn’t left much time (or emotional capacity!) to produce SuperHouse videos.
This is a big change in my personal circumstances, so hopefully I will be able to make more progress on SuperHouse now.
While working on new SuperHouse episodes I’ve upgraded my surface mount reflow oven. Most things I design are assembled in factories, but about 8 years ago I set up a toaster oven with a temperature sensor so I could do quick reflow at home for prototypes and small production runs.
Some years ago I upgraded the toaster oven by fitting an Arduino based automatic temperature controller, and since then I’ve baked several thousand circuit boards in that little oven. However, the time has finally come to replace it with a proper semi-professional reflow oven.
The T-962A is currently the most common cheap desktop reflow oven, but I need something a bit bigger so that I can run a few dozen boards at a time. I decided to go for its big brother, the T-962C.
Yes, I know the camerawork is terrible! Normally I’d re-film anything that looks as bad as some parts of this vlog, but TBH I can’t be bothered for a quick update 🙂
Grass grows at different rates depending on the time of year, so sometimes it’s necessary to change the Automower schedule to suit the growing conditions. Now it’s winter here in Melbourne and my grass is growing very slowly (and even dying off in patches) so I need to reduce the mowing time.
Husqvarna have made it very easy to change the settings directly on the mower, allowing me to change it from 2 hours of mowing per day to 1 hour.
The main sales pitch for robot lawnmowers like the Husqvarna Automower is that you don’t have to mow your grass, ever again. It always looks neat. But there’s a second claim: that trimming the grass just a tiny amount each day also results in healthier grass. Time for a direct comparison of the main lawn area maintained by the Automower, versus a patch of grass that I have been mowing manually.
