Yesterday I referred to using DELAY in Node-Red to slow down one of the Blynk controls. To backtrack a little…  We’re talking here about controlling devices such as ESP8266 boards using MQTTT – which I maintain is the best way to have a boatload of devices around the place and…

A Better Day

October 29, 2015October 29, 2015 Peter ScargillBlynk, Blynk App, ESP8266, Node Red2 Comments on A Better Day

A better day today. After switching my WIFI to a separate access point, up to now the WIFI is holding – I’m not convinced but for now all seems well. That has allowed me to spend a little more time with Blynk – and after chatting to the Node-Red node…

Orange Pi, BAIDU and foreigners

October 26, 2015October 26, 2015 Peter Scargillbaidu4 Comments on Orange Pi, BAIDU and foreigners

Updated: Do they just have it in for me or is this typical? I’ve been trying to get an account with Baidu for some time as some of the Chinese suppliers often put firmware up there. So, armed with Google translate, I went off to get an account, filled in…

The new ESP

October 23, 2015 Peter ScargillESP82664 Comments on The new ESP

In case you missed it – extracts from forum conversation with Swee Ann Teo, CEO of Espressif about the new chip – which I understand will have Bluetooth as well as WIFI and be a lot more powerful. Also in that discussion is a promise to support the existing chip…

Blynk App

October 22, 2015October 22, 2015 Peter ScargillBlynk, Blynk App17 Comments on Blynk App

I’ve re-written this blog today – as the people at Blynk have been quite useful – promising to fix some items I’ve griped about/commented on. I hope they don’t mind me pinching some of their imagery. One of the problems with home control – is making a nice web interface…

Pion One

Nextion Talking Thermostat

October 13, 2015March 20, 2017 Peter Scargillnextion, Raspberry Pi 2, Scargill24 Comments on Nextion Talking Thermostat

Yes, I changed the title. As often happens with these things, I got carried away. The Nextion display is a touch-sensitive intelligent display.  Essentially, you buy the display and you program it with a free editor serially – which lets you easily place icons, buttons, images, text, gauges and more…

Raspberry Pi Serial and Node-Red issues

October 8, 2015October 9, 2015 Peter Scargillnextion, node-red, node.js, Uncategorized3 Comments on Raspberry Pi Serial and Node-Red issues

SOLVED: Node-Red serial I/O Looks simple doesn’t it – tie RX and TX together on your Raspberry Pi and press the button – text comes out of the other end – except that it doesn’t. More likely the Pi will CRASH (not something you see every day). Serial out seems…

Talking Raspberry

Updated 21/DEC/2015 This entry is now DEAD. Google have changed the goalposts and removed the API access for their language translation and text to speech system so that the base program behind this work – a program called Normit – is no dead in the water. I’m doing an update…

As of right now – this is page one of my node-red setup – today I managed to get text to speech running on the Raspberry Pi (not on the Orange Pi as that’s not having sound at all) and note at the bottom right – my latest additions ready…

Raspberry Pi Monster Script Part 3

October 4, 2015August 19, 2017 Peter ScargillRaspberry Pi, Raspberry Pi 244 Comments on Raspberry Pi Monster Script Part 3

I’ve updated the script – gotten rid of MYSQL – too many questions about SD life – and I have to say, SQLITE3 – though slightly different takes mininal modification of SQL assuming you’re doing things like logging of data and relatively straight-forward queries – it really is worthwhile. Apart…

You Big Jessie

October 3, 2015 Peter ScargillRaspberry Pi 22 Comments on You Big Jessie

While waiting for inspiration as to why the new ESP8266-based controller OTA coding is crashing the boards, I thought I’d have another go at rescuing my ill-fated Orange Pi.  After much time spend putting operating systems onto microSD and failing to get ANYWHERE, I gave up. Having short of SDs…
