In learning how to use Node-Red I’ve changed my coding countless times as I’ve found better ways to do things. Please note that in 2017, the way I use global variables here is out of date. It still works but for example context.global.fred=1 is now written as global.set(“fred”,1). Read this…

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…
Node-Red Madness
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
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…
Raspberry Pi Processor Monitoring Widget
Don’t you just love it when people produce really useful tools for free!! And so it was that I got up early this morning to get a little Arduino/ESP-01 research done and got side-tracked by Google+ And the result – this baby. This is a tiny piece of software that…
A Node-Red Websockets Web Page
Updated 26/04/2015 I’ve been after this ever since I discovered Node-Red.. and right up until this yesterday I was tearing my hair out – having settled for NETIO as my interface of choice and constantly being annoyed by the slow pace of progress with this interface. So what is this…
The Raspberry Pi SD Wear Issue
Reading around the web it is easy to see that SD memory and lifespan are very poorly understood. There are conflicting explanations of lifespan, there are solutions which don’t work because someone didn’t actually test them before writing up … what a mess. So here’s the deal. SD memory (the…
Slimmer Raspberry Pi 2
In the process this week of producing a new new Raspberry Pi2 with just the stuff I needed on it I thought I’d have a go at removing unnecessary programs from the Pi – that is the ones that come with it – after all the Debian installation from the…
Bringing the Pi into the PC world
So you have your sparkly new Raspberry Pi and the first thing you need to do is remotely access it from the PC… and so you install TIGHTVNC… and put that on the PC and they talk to each other and…. no clipboard… This link got me out of a…
