The Mighty T3

November 30, 2016November 27, 2017 Peter ScargillUncategorized35 Comments on The Mighty T3

Some time ago, I wrote about the FriendlyArm NanoPi M1, a simple, low cost board which seems to hold it’s own against the Raspberry Pi2 in all but GPIO control – that’s not to say there is anything wrong with the GPIO but you have to write your own stuff…

A Little Dashboard Something

November 26, 2016November 26, 2016 Peter ScargillNode Red, node red dashboard5 Comments on A Little Dashboard Something

Something for the weekend sir? How about a simple means to get visual and tactile feedback from node-red-dashboard buttons? Or rather than large buttons – icons you may create or obtain yourself in a node-red-dashboard template. To backtrack: For my own home control endeavours, I’ve been using a number of…

Dazzling LED ESP8266

November 20, 2016November 23, 2016 Peter ScargillESP826631 Comments on Dazzling LED ESP8266

So… the other day, a parcel turned up for me – some samples from Itead. One of the boxes contained 4 strips of LEDS and a controller. The strips are maybe 20mm wide aluminium with staggered SMT LEDs on them – first a warm LED, then a COLD LED then..…

Amazon and the UK

November 16, 2016 Peter ScargillAmazon20 Comments on Amazon and the UK

I thought you might like to see a communication with Amazon and my responses.. I am pretty annoyed as it is not the first time an American company has launch stuff around the world – keen to get sales going but not so keen to provide international customers with the…

New This Weekend

November 13, 2016November 13, 2016 Peter ScargillGeneral20 Comments on New This Weekend

Over the weekend I have added a new MENU item to the blog – COMMENTS – thanks to MrShark for that idea.  Menu top right. The page shows the last 100 comments which will hopefully be useful. I’ve also added an experimental e-newsletter (again on request, several people said they’d…

How Not To Do PCBs

November 11, 2016December 5, 2016 Peter ScargillGeneral12 Comments on How Not To Do PCBs

My usual stance is to be nice to Itead, I’ve been dealing with them for some time and although I have absolutely no commercial or personal tie up with them, they do send product samples from time to time as do many others – and I usually end up writing…

Size Matters… Neo AIR

November 11, 2016December 20, 2016 Peter ScargillGeneral34 Comments on Size Matters… Neo AIR

When it comes to size, this one is as good as any… the FriendlyArm Nano Pi Neo Air. You’ve probably read my blog about the Nano Pi Neo, a device I can only describe as “cute” because of it’s really small size – but powerful non-the-less. Well, the AIR version…

November 11, 2016November 11, 2016 Peter ScargillESP8266, i2c, Raspberry Pi 2, Raspberry Pi 350 Comments on I2C Expansion for Pi and ESP8266

Want 64 GPIO pins on your ESP8266 or Raspberry Pi? Read on. If like me you are not THAT familiar with I2c, you might find the results of my  experiments interesting and perhaps even useful. If like me you are not THAT familiar with I2c, you might find the results…

Toying with HA-BRIDGE

November 10, 2016November 13, 2016 Peter ScargillGeneral29 Comments on Toying with HA-BRIDGE

Thanks to readers in here I’m having a play with HA-Bridge to act as a device gateway between my home control (generally ESP8266) devices and Amazon Echo. I’m only scratching the surface and haven’t gotten past “Alexa, turn X on”, “Alexa turn X off” and “Alexa set X to 30%” …

Netdata

November 6, 2016 Peter ScargillGeneral6 Comments on Netdata

This is NEAT – reader Jay brought this to my attention this afternoon – here’s the link. So Netdata is a system monitoring tool – but better than any I’ve seen up to now – certainly on the Raspberry Pi – so I simply followed the instructions in that link,…

POW, TH16 AND DUAL

November 5, 2016November 13, 2016 Peter ScargillESP8266, itead, sonoff46 Comments on POW, TH16 AND DUAL

Ok, this entry will be in 2 parts – I’ll do some digging soon – but as I’ve had several requests for this… So what you’re looking at above are the Sonoff Pow, TH16 and DUAL mains controllers. These are ESP8266-based low cost controllers to turn things on and off.…

The Light Fantastic

November 4, 2016November 9, 2016 Peter ScargillESP8266, GY-30, home control, i2c10 Comments on The Light Fantastic

This morning, a long-forgotten package turned up for me – a cheap but accurate light level sensor from China – claimed to be around 1 lux accuracy and giving a direct output in lux. A small board is available here in Britain for around £4 or the identical board from…

Fauxmo Alexa Delights

November 3, 2016November 3, 2016 Peter ScargillEcho, MQTT, node-red, Paho49 Comments on Fauxmo Alexa Delights

I’m going to cut a very long story short here.  I’ve been looking at ESP8266 emulations of WEMOs because up to now this seems to be a popular device to emulate when using with your talking Amazon Echo. If anyone wants to come up with something that will take ANY…

Node-Red Objects to File and Back

November 2, 2016September 14, 2017 Peter ScargillNode, Node Red, node-red, node.js29 Comments on Node-Red Objects to File and Back

This is a major re-write of a year-old blog. At the time, I simply wanted to store a global object in a file and retrieve it. Things have changed, I realise the way we did this was awful – hence the re-write. One way is to save the object as…
