Sonoff 4CH 4 Channel Mains Control

January 31, 2017 Peter Scargillitead, sonoff, sonoff 4CH68 Comments on Sonoff 4CH 4 Channel Mains Control

  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

January 31, 2017March 20, 2017 Peter ScargillGeneral15 Comments on 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

January 28, 2017February 1, 2017 Peter ScargillCanvas, HTML5 Canvas7 Comments on 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

January 25, 2017January 25, 2017 Peter ScargillGauges, Node Red, node red dashboard, node-red, node-red-dashboard16 Comments on 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

January 25, 2017January 25, 2017 Peter ScargillGauges, node-red, node-red-dashboard2 Comments on 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

January 23, 2017May 31, 2020 Peter ScargillLCD, Node, Node Red, node red ui, node-red, node-red-dashboard4 Comments on 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

January 22, 2017January 23, 2017 Peter ScargillLCD, Node, Node Red, node red dashboard, node-red-dashboard, node.js66 Comments on 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

January 21, 2017January 22, 2017 Peter Scargillno, node red dashboard, node-red, Steel Series Gauges27 Comments on 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

January 20, 2017January 21, 2017 Peter ScargillGauges, General, Node, Node Red, node-red, node-red-dashboard, node.js, RGraph10 Comments on 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

January 19, 2017January 19, 2017 Peter ScargillGeneral, Pine 6410 Comments on 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

January 12, 2017January 16, 2017 Peter ScargillFriendlyArm, NanoPi A6483 Comments on 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

January 12, 2017January 21, 2017 Peter ScargillGeneral

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

January 11, 2017January 13, 2017 Peter ScargillA64, FriendlyArm, Sol, solar power, Xenial

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

January 10, 2017January 13, 2017 Peter ScargillNode, Node Red39 Comments on 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…
