A parcel turned up for me today – the Sonoff 4CH. You may recall I wrote some time ago about a smaller version they put out and I was quite scathing about the wiring. I turned out as you recall that this was a third party product and they…

The Mint Experiment
Anyone who’s known me for years knows I’m a died in the wool Windows man. Over many years from Windows 3.1 onwards, I’ve done down that road until ultimately all my machines are now Windows 10 – and I have to say that, while it could be argued before Windows…
HTML Canvas Touch Position
I’ve had some great fun the last few days working on my gauge – and as part of that I thought at one time of making it touch-sensitive. Thankfully my senses prevailed in the end but not before coming to terms with a need to understand how the HTML5 Canvas…
Thermometers
Three thermometers in a row for Node-Red (or as many or few as you like really) for Node-Red Dashboard. Another fine example of simple gauges and unlike some it is easy to make multiple gauges on one page – I will demonstrate three. Here is the library source, I grabbed…
Yet Another Gauge
This one has been long in coming because despite my quickly evolving knowledge of Javascript and Canvas, that last leap – getting variable information out of a canvas and back into Node-Red – has kept me on edge for a couple of days now. Dave (DCEEJAY) pointed me to various…
Another LCD
When writing that last blog entry about an LCD with time and date display and programmable temperature for Node-Red Dashboard, it occurred to me that it would be worthwhile making a simple one-liner (6*1) LCD with a 20-character display. At the same time I wanted to simplify it right down…
LCD Display for Node-Red
As must be obvious by now, I’m on a roll here. Having decided that Node-Red Dashboard is the way forward ( would in the past have used BLYNK or Imperihome) I’ve been getting to grips with the dashboard and as you’ll see if you check recent blogs I’ve had a…
SteelSeries and Node-Red
You should read the previous blog entry before this one – as the principles are the same as are some of the details such as the location of your /myjs folder for Node-Red – so read the other article first. This guage IMHO is the best yet! To run the…
RGraph with Node-Red
Having gone from spending countless hours staring at HTML5 CANVAS, I’m now at the “meh” stage as it starts to dawn on my how it works. And so it was that I stumbled on RGraph – or put another way, Christmas for widget-lovers. If you’ve been following these blog entries…
A Thermostat Weekend
As I make changes and I don’t want to bore readers – I’m adding sections at the top of this article and moving earlier versions of the stat down the page. If you are new to this you might want to start at the bottom at the point in this blog…
The Pine 64
Just a quicky this morning as I’m busy working on a LED for the thermostat control (thanks to some help from the author – I’m quite excited) as well as bench-testing some NanoPi 64 and M3 units. So what you see here is the Pine 64 – which, like the…
FriendlyArm NanoPi A64
Don’t you love reviews that tell you all about a new product, print out all the specs then leave you to discover the horrors all on your own because they didn’t ACTUALLY test the thing? Well, this isn’t one of those reviews. But I will give you the spec. Even…
Some Background
Far too often in blogs like this we “assume” that everyone is following along, so for the sake of boring regular readers…. the background to much of what you will see in this blog, revolves around my home control project which started off using an Atmega1284 chip as a controller…
A Fantastic Day
It’s been a good day today. Let me clarify that – a good day considering I’m in the Northeast of England, wishing I was in the south of Spain and currently freezing to death. I got up far too early with ideas in my head about the Thermostat – to…
New Day, New Dial
WHAT a day I’ve had – messing around with a supposed DIY Alexa that isn’t… and getting to grips with dials. I wasted a lot of time on this (sorry Dave) before finally grasping the solution. Here is the LATEST short video (Jan-10-2016) So – in the last blog entry…
Happy New Year 6200+ members
And only days after I wrote that, we’re well over 6,200 of you, registered in here and climbing! Thanks to everyone and especially those who’ve submitted great feedback over the last year. (Update June 2017: That figure is now approaching 7,500!) A quiet New Year’s Eve – out with friends…
