December

25th

Got some 12V dc colour-changing LED pond lights for Christmas, to go in our smart pond. These come with an infra-red remote control, which will replaced by an IP gateway.

November

18th

My smart pond project is complete and the pond prepared for winter.

4th

My 150W pond heater arrived today, just in time as the weather is turning more wintery. This is part of my smart pond project and will be intelligently controlled by my contextual smart home based on ambient temperature.

October

Been recovering from COVID19 for the last few weeks :-( Slowly getting back into my various smart home projects.

7th

Interesting challenge today, encapsulating the LED strips in clear expoxy resin. I did an initial pour to about 3mm depth and will re-test the strips to ensure this hasn't affected them.

3rd

The smart garden lounge composite decking is complete!

September

28th

Second day installing the composite decking and the smart garden lounge decking is nearly complete. Rain stopped us and I have also run out of T-clips. Some more have been ordered.

26th

The composite support joists are installed for my smart garden lounge project

25th

The concrete foundations are complete for my smart garden lounge project

17th

Installed the composite fencing behind the smart pond.

9th

My composite decking and fencing was delivered today, for my smart 'garden lounge' project. About £1700 and weighing 850Kg!

Completed the installation of my 'Shed Path Light'. This LED strip is under full contextual smart home control and is a zero touch user experience.

8th

Finally finished digging the last bit of trench! This takes the power and networks into my shed, to be connected up with power and networking already installed there. The next job was to run the rest of the cables through the ducting and bury it all.

The patio catches the morning sun but, it looks like my recent digging may have killed the grape vine :-(

7th

I'm now finishing the final stage of trench work, to get the network and power cables into my shed.

6th

It's been a big job but, the patio is finally completed! It's fair to say that my hands and arms are suffering a bit will the daily manual labour involved.

5th

The new smart pond is pretty much complete :-) The grass seed has taken well. I've got new composite fencing arriving, which will allow me to finish the back of the pond.

August

25th

This is the 45cm deep trench along the back of the patio. 25mm conduit is being used to run both mains power cables and 4 Ethernet networking cables. I'm using armoured power cables and these run about 30cm below the network cables.

24th

As I started to lift up some of the patio stones, I realised a lot of them had already moved due to roots from the plants next door. This basically meant I had to lift up the whole thing and will have to re-lay it all :-( With the patio lifted up, the scale of the root problem can be seen. Some are over 30mm thick and run into the lawn.

20th

The marked out area here shows my planned smart 'garden lounge'. Knowing the shape and size, I can now order the composite decking required.

July

11th

These last few days, I've also been working on a project to enable voice announcements.

8th

Spend this morning digging trenches for this 25mm conduit. 70m of it in total, to contain network cables and armoured power cable. This is for my patio, smart pond, garden lounge and future hot tub.

7th

I'm still busy 3D printing the brackets to allow me to start fixing my cables trays in place. I'm currently 3D printing three every day, since they take just over 3 hours to print each one.

2nd

I've been doing some more research on hardware for voice announcements. The objective is to build an IP-networked 'active' device that can be installed at various points around my home and can be sent an event, causing it to speak out the requested text, with no dependencies on cloud services (i.e. it's all local and inside my home). I've got the basic concept working well, using an Arduino but the audio quality is simply not good enough, so I'm now looking to use a Raspberry Pi instead.

28th

Lots of 3D printing of the brackets for my loft network cable tray project this week. I've had to order a lot more PLA.

25rd

I have designed and started 3D printing the brackets for my loft network cable tray project.

23rd

Ordered a load of cable tray hardware to tidy up the network cables in my loft. The goal is to tidy up the current cables and install a few more. This is just half of the eight 3m × 100mm trays and I also have some 90 couplings. This is a practice run for my next, self-build smart home. Hardware costs were about £140 including delivery. More on this project.

21st

And this is the 3D printed for the GJD Opal XL PIR sensor. It works perfectly.

20th

I order to mount the GJD Opal XL PIR sensor better into vertical corners, I designed a new sensor module mount for 3D printing.

19th

16th

This week, I've been doing some more data analysis on my hot water system.

14th

Work on my new smart pond has been halted by lots of rain.

May

27th

Spent most of today coding in Java, updating and training neural nets as part of my smart home's artificial intelligence. The focus of today's work was on better detection of when a question has been asked.

22th

Today, I'm evaluating this non-contact liquid sensor.

15th

The focus of my work this week has been on my robotic lawn mowers and a project to integrate a robotic lawn mower with my contextual smart home.

7th

The focus of my work this week has been on my smart home diagnostics. This is a number of 'views' that give real insight as to how well my smart home is working.

2nd

Although, I generally avoid Wi-Fi for smart home sensors and devices, sometimes it is handy to be able to add a wireless multi-sensor in a room. To achieve this, I've developed my own temperature, humidity and light level projectbased upon the NodeMCU ESP8266.

April

23th

I have 3D printed a mount for the proximity sensor for the reactive smart mirror in our ensuite bathroom.

10th

My project to build a reactive smart mirror for our ensuite bathroom is progressing really well.

9th

My 3D printer activity monitoring project is tested and complete :-)

2nd

This Moorebot Scout caught my eye recently. It's an AI-powered autonomous home robot with 1080p camera and night vision. I have backed this project on Kickstarter.

March

25th

I've been updating my 3D printer activity monitoring project, to allow my contextual smart home to better detect when my Ender 3 Pro 3D printer has finished printing.

23rd

I'm working with a friend on an Arduino module to support Power over Ethernet (PoE) for smart home applications. We hope to have the first prototype off to manufacturing very soon. This will work with other boards such as my Arduino Mega2560Pro project.

20th

This is my PIR sensor and new 3D printed mount.

19th

I wasn't happy with the supplied mount that came with an external PIR sensor, so I designed my own to be 3D printed.

17th

This morning, I've been doing even more work with Apple iOS shortcuts on my iPhone. You don't have to be embedded in the Apple eco-system to be able to do really powerful things in the contextual smart home. You don't even need to use HomeKit.

16th

More testing on my Arduino Mega2560Pro project to make this another of my smart home smart home building blocks.

15th

I'm doing more work on my lighting smart switches this week.

9th

I've designed an enclosure for my cycle USB charger circuit, to be 3D printed.

9th

The PCB and parts arrived, to allow me to build up my new cycle USB charger circuit and test it.

2nd

This week, I've been working on a project I've been meaning to do for ages. It's a sensor to detect my washing machine playing a tune, which signals the end of the washing cycle.

This is now working really well!

February

18th

This week, I've been doing more on my connected vehicle project. The objective is simply to use my cars to provide additional useful context to my contextual smart home.

9th

The object of this 5V relay board project is simply to provide a cheap and reliable way to control high-current, mains-powered (240Vac and up to 10A) appliances and lighting, fully integrating them into my smart home and allowing intelligently control.

January

1st

I've been evaluating and reviewing the RCWL-0516 microwave motion sensor and I've been really impressed with it. This is a big step forward in smart home occupancy detection.
