September 25, 2023 A Long Distance Drive in the Atto 3 We drove our BYD Atto 3 from Auckland to Wellington, and this was the first long distance trip we have taken it on. So how was the charging and how much did it cost? Categories Electric Vehicles Comments: 0
August 20, 2023 Adding a Dashcam to our BYD Atto 3 Installing a front and rear dashcam in a BYD Atto 3. Although the Atto 3 has a dashcam, it doesn’t record when parked. Dash cameras are great, and I like having them in all of our cars. The first one i installed was around 9 years ago and they have saved us a few times when involved in a fender-bender that wasn’t our fault, and really helped a couple of times when there has been a carpark ding.

August 6, 2023 Appliance Completion Notification with Node Red Use of Node Red and Javascript to monitor power to an appliance and notify when complete.

August 4, 2023 Tasmota Rule Examples Below are some rules for Tasmota that I’ve used over the years, including doing basic standalone automations (no Home Assistant, no Node Red, or other additional tools). Standalone automation can be handy, and in simple cases you don’t need any working wireless for basic functions. If you install smart devices, you can safely disconnect your networking (eg if you sell your house) and still have some basic smart functions. Categories Home Automation Comments: 0
April 28, 2023 Cheaper Sodastreaming with bulk CO2 We like our bubbly water, and although you can get fridges that carbonate… they are horrendously expensive. The next best thing is a sodastream machine, but again… this can be a huge cost if you stick to the sodastream brand cartridges. So, what options are there to DIY ?

October 14, 2022 30 Years, and my Digital Mobile Tour It seemed like I’d owned a few mobile devices in my lifetime and a while back I gradually built up a list. The list showed that it was around one per year starting in the early ’90s, although there were times I had a work and personal phone or tablet at the same time. I thought I’d jog my own nostalgia a bit more by writing a bit of history of the cellphones in particular, and why I had them. Categories Mobile Phones & Android Comments: 0
October 6, 2022 NZ Retro Caravan Awning Guide In 2016, we had a custom awning manufactured for our New Zealand made, 15″ 1965 Zephyr Deluxe caravan. A few people have asked about it, so I have documented a bit of the process. Categories Retro Caravans Comments: 0
September 29, 2022 Zemismart KS-811 with OpenBK7231N/OpenBeken Recently a friend bought some Zemismart wall switches and they have a BK7231N chip rather than an ESP8266.

July 8, 2022 WB3S replacement for Home Automation devices More and more home automation devices from China are coming with no ESP8266 module, especially the TUYA based ones. Some are coming with a WB3S (which is different to the TYWB3S), but this can easily be removed and replaced with a cheap ESP12F (or similar) module. Categories Electronics/Home Automation Comments: 4
June 27, 2022 Used EV Payback (Part 2, Was it worth it?) How much to you save buying a used EV, and is it worth it? How long is the payback? This is my actual calculations about four years later and close to 100kkms on the odometer of the 2014 Nissan Leaf I purchased. Cutting to the chase, it was a LOT better than my estimates, and I wish we’d bought two of them. Categories Electric Vehicles/Home Automation/Opinion Comment: 1

November 9, 2021 Xiaomi 10T Pro Updating (2021) This is the method I followed for my Xiaomi Mi 10T Pro to get from my previously installed AOSP ROM to a stock based ROM (I’ll change to a modified stock ROM later). It includes Root so a bunch of useful things can be installed. I had a nice AOSP ROM previous to this, but the camera was a stumbling block – the Xiaomi stock camera is so much better.
