So a parcel arrived for me this morning in the post. A Nextion display. And what is that, you may well ask? Think of something like a thermostat or really any home control situation, at some point you have to stop sending text commands from an expensive PC and reduce…

Driving me NUTS
This has been driving me mad and I’ve only just found the answer – thanks to some clues people have given me – but as many of the responses were wrong – you might well find this interesting. I have a an array of 180 bytes – for 60 serial…
More Websockets
In a previous blog item here I covered the use of MQTT, jQuery Mobile and Websockets to make a controller web page for mobile phones/tablets etc. here https://tech.scargill.net/mqttjquerywebsockets-controller/ I showed just a basic and not too pretty page with buttons that would control real items, in my case via Websockets…
Windows 10–the Missing bits
Slight diversion as I’ve just been upgrading my PCs to Windows 10 and a friend of mine pointed me to changes as against previous versions – i.e. what’s missing from Windows 10. Here I’ll take a look and give my comments. Firstly I should say as a hardware-oriented guy I…
MQTT/JQUERY/WEBSOCKETS Controller
I wrote a while ago about using web sockets as against something like NETIO for controlling the home – most folk liked the article but I think part of it was a little complicated – and at the time I’d not really thought it out to make it as simple…
Testing ESP8266 WIFI
Having had mixed results with both the ESP-Arduino environment and the normal SDK (1.3.0 with latest patch) and C, I decided this morning to up the game and do some focussed testing. So – I made a simple loop with ESP-Arduino, connecting to WIFI, connecting to MQTT and publishing a…
EasyTransfer for ESP8266
I’m going to describe here the transmitting side of the EasyTransfer system as used in Arduino – the reason I did this was because I wanted to ship a bunch of binary data from the ESP8266 to the Arduino where I have a nice little wall mounted LCD display –…
ESP8266 Mesh
Here it is – the ESP8266 Mesh English doc – who will be first to get this going? http://bbs.espressif.com/viewtopic.php?f=51&t=929 The Chinese docs have been out for some time as has the mesh SDK but the English docs just came out today – have fun.
Home Control Scheduler
This is a follow-on article from my blog Home Control 2019 which concerns itself with IOT around the home – you might want to read that first. Scheduler is now defunct, replaced by node-red-contrib-bigtimer. Many articles on DIY home control tend to scratch the surface and you don’t find out…
The MIT Boston Trip with Espressif Systems
Some time ago, the CEO of Espressif, makers of the lowest cost WIFI-enabled processor on the planet (a chip I’ve blogged about frequently in here) invited me to come with them to MIT at Boston to the FAB11 conference. As it turns out this was a rather small affair featuring…
ESP8266 Arduino NetIO Server Demo
This week as regular readers know I was far away from our little home in Spain – in fact I was at MIT (Massachusetts Institute of Technology) in Boston, helping promote ESP8266 technology (why? because I could). Along the way I met up with Ivan Grokhotkov who as some of…
Node.IT
Many of you have asked me about the devices I called ESP-210. I’d planned to take a boatload of early production boards with me to Boston this coming week – donated by Pontus Oldberg – but the couriers let us down (there’s a surprise). So – I don’t know how…
FAB11 – Boston
This coming Monday/Tuesday/Wednesday I’ll be working with Espressif CEO Swee-Ann Teo, Jeroen Domburg, Ivan Grokkhotkov and others at FAB11 in Boston – demonstrating how to use the ESP8266 chips in home control and other applications. Heading off from Alicante (Spain) first thing in the morning tomorrow (Sunday) and arriving late…
