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.

Home EV Wallcharger Setup & Installation Tips

Having had electric vehicles for a few years now, I thought I’d share a few tips and photos regarding our current EV charging setup. We currently have 2 EVs (both that live outside) and 2 charging points, one beside the other.

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.

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 ?

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.

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.

Zemismart KS-811 with OpenBK7231N/OpenBeken

Recently a friend bought some Zemismart wall switches and they have a BK7231N chip rather than an ESP8266. This outines the OpenBeken project and how it can be used in the switch in a similar way to Tasmota/ESPHome.

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.

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.

Jaycar Duinotech ESP32 Wearable Board Fix

I couldn’t wait for some cheap ESP32 Dev boards from China, and Jaycar happened to have some half price ESP32 boards (Duinotech wearable ESP32 Development Board) so I grabbed a couple to play with. Unfortunately I had a couple of issues flashing them and keeping them stable so had to find a solution.

I have a low cost WH1080 USB Weather station, connected by USB to an intel NUC running docker (x86). These weather stations have a bug in that they occasionally lock up and stop sending data. I implemented an automated way to reset it.

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.

Caravans at Beach Hop, 2021

Beach Hop rolled around quickly for 2021 as the last one was just in November. Some awesome new vans on view, and the usual suspects back with there fantastic renovations, displays and creations. I’m looking forward to next year’s Caravans & Classics sponsored light show – it was organised at short notice this year and not a lot of vans…
