There was a time in the distant past (in my case this morning) when running I2c natively in Node-Red on anything other than a genuine Raspberry Pi was a nightmare. Not any more. So in a recent blog I’ve covered a pair of Node-Red nodes which allow GPIO access in…

Thermostat
As you do I just happened to be looking through the latest NODE offerings for Node-Red and spotted this little number – a thermostat node. Now I have my own controls for this and I’m happy with them but they’re generally done with code – and I saw this –…
SSD1306 on the NEO Plus2
You might recall some time ago I wrote about using Python on the Orange Pi Zero etc to run the little SSD1306-based displays. Despite that being successful I did have a nagging doubt about the LUMA library because later on – when doing some apt-get upgrades I got a segmentation…
NanoPi Neo PLUS2
No, I’d not heard of this one either until a couple of weeks ago. With a small form factor, 2 USB sockets and a $25 price tag it has to be worth a second glance. I’ve used the NEO and this is definitely an improvement – H5 processor, the Ethernet…
The Script Step By Step
I thought it might be useful for beginners to go through the installation of Raspberry Pi 2 Jessie (July 2017) and “the script” – so here goes… I’m also doing this to help a friend who had issues installing the script on a Pi late last night, most likely due…
Simple Scope
You may have noticed that I’ve been working on my ESP8266 home control software (see the updates elsewhere along with new diagram), specifically upgrading and adding to the number of OLED and LCD displays I can handle, either by I2c or SPI. I’ve been doing a lot of optimising and…
Icons
In case you were wondering – no, I’ve not gone off the boil, I’ve been quietly beavering away on my ESP8266 code since deciding to abandon the old ESP-01 and adding fonts for displays. Right now I’m focussing on the QD-Tech boards – 120×160 but I’ll eventually migrate the use…
The Sonoff 4CH Pro
The 4-channel Sonoff 4CH Pro is a new product from ITEAD, available from them directly or from Amazon in the UK– though you might reasonably question why the UK Amazon price is higher in pounds than the original is in dollars. Essentially the unit is a development of their earlier…
NanoPi M3
This is a July 2017 update to the blog entry about the FriendlyArm NanoPi M3 board. Smaller than a Raspberry Pi but with a boat-load of facilities, the board includes: A3 Octa-Core processor (handy for multimedia) S5P6818 1GB Ram 3.5mm audio jack 1GBPS Ethernet port WIFI Bluetooth MicroUSB for power…
