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…
Project Boxes
For those few of us left in the world who don’t have 3d printers… boxes for our projects are always an issue… I’ve decided I want to use DIN rail enclosures because in Spain, the large household Din rail mains boxes are dirt cheap – just need some enclosures for…
Customising Node-Red Dashboard Buttons
This entry is about creating custom buttons for Node-Red Dashboard. If you’re looking in for the first time – this simple cyan rectangle on the right is what Node-Red Dashboard buttons currently look like. Without some effort, the cyan background colour can be changed as can the text colour but…
The Ongoing Knob
I refer you to this article if you’re new in here – https://techspecialsdaily.store/more-dashboard-goodness/ – we’ve been having a lively discussion and lots of exciting new possibilities coming out of a chance discovery of the JQUERY KNOB and what is now our ability to integrate that with Node-Red. The purpose of…
The Orange Pi Zero
Those of you who read my stuff will know that I’ve never been impressed by the Orange Pi boards – the utter lack of communication from the company really is stunning and initially the boards used to get very hot – but then came Armbian and all that changed –…
More from Sonoff
Today I got a couple of new(ish) gadgets from Sonoff – one being a UK version of their WIFI mains adaptor. So the point of this if you don’t know Sonoff is that their stuff is solid and inexpensive – not two words you normally find in the same sentence.…
Merry Christmas
Some of you may be heading off home to see family so we might not hear from you for a little while. Others will be settling down at home for a Christmas of gadgets… Either way, by Christmas there’s a good chance there will be 6,000 of you signed up…
Virtual Pi
Every time I screw up badly, I end up having to go through to the house, swap SDs on the Raspberry Pi and start another backup. AND I’m told by our friend from Raspbian that I should not be doing this as live backups are asking for problems. Now, to…
More Dashboard Goodness
Last week, I got as far as some new buttons on Node-Red Dashboard along with fancy colour change and vibrate – you’ll see some new buttons if you head off back to that entry. So, what’s those round things with numbers in them? No, not more gauges – but CONTROLS…
