SuperHouse Vlog #60: Maker Faire Shenzhen, China

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.

SuperHouse Vlog #57: ESD mat for my electronics work benches

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:

SuperHouse Vlog #56: Internet Vision Technologies is no more

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.

SuperHouse Vlog #55: The T-962C surface mount reflow oven

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.

I wrote up a tutorial about DIY surface mount assembly for Freetronics: you can read it at Surface Mount Soldering With A Toaster Oven.

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 🙂

SuperHouse Vlog #54: Husqvarna Automower scheduling

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.

SuperHouse Vlog #53: Help! The Internet killed my toaster!

A major outage at Amazon Web Services this morning left millions of people with broken home automation devices: door locks, heating, lights, ovens, even doorbells.

Don’t let your home automation system be dependent on external services!

I always keep two principles (or rules) in mind when building my own systems.

Rule #1: No external dependencies.

Rule #2: Mechanical overrides.

SuperHouse Vlog #52: Automower grass quality

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.
