The Trip: As regular readers may know, early in 2016 I worked in Spain on a contract with some great guys to analyse information from ESP8266 chips. Without going into any commercial detail, this is what I brought back from that trip as well as other lessons learned since then.…

Terminal Login
I made this as a continuation of my current work with the NEO2 but there is no reason why this could not be adapted to other boards. There are also many ways to achieve the same thing i.e. colourful terminal login – this is merely a what I chose to…
NEO2 NAS Part Two
I’ve separated this off as it has gained a life of it’s own. When I originally opened up the NAS box from FriendlyArm and plugged in my NEO2 (same company) I’d just planned on trying out the free NAS software. Little did I know how far this would develop…
Coloured Terminal Prompt
We live in a world of colour and most of us have colour monitors. Why then should we put up with boring terminals? Check out this coloured prompt code.
NEO2 NAS Part One
This started off as a simple bit of fun to see if the FriendlyArm NAS box was any good – I had no idea it would turn out to be so much fun.. read on… My first NAS was the NetGear ReadyNAS duo – some of you may recall this…
NanoPi K2
What, not ANOTHER board from FriendlyArm? And yes, you’d be right to wonder why I’m doing a bunch of articles on them right now – well, it just so happens I got a box of stuff all at once so I thought I’d get them all out of the way…
NEO REBOOT
I have covered the FriendlyArm NEO and NEO2 boards here before now and generally been in favour – but for one little item in common with many other boards – little or no IO support – well, that just changed. Read on… With no apparent way to get to the…
Big Nextion
Quite a while ago now I did a project based on the little Nextion displays, resistive touch-LCD displays which run on serial commands and come with an editor to make simply touch displays for even the simplest of micros. Well, that project has proven to capture a lot of interest…
A Quick Plotly
Some time ago I wrote about HighCharts – a wonderful set of Javascript tools for doing graphs – and I gave an example of getting the graphs into Node-Red. I’ll not repeat that as you have the link above. At the time I’d not added in databases, I’ve since made…
ESP8266 Code Update
The code that forms a series of articles on this blog has now not been updated for some time – simply because it “just works” and has been doing so reliably for many months. However, I’ve been wanting to add bits to it and my problem was I was running…
Uninterruptible Supplies
Need a power supply with battery backup that shuts off your PI or similar gracefully when the battery gets low and starts up when the battery recovers? I’m sure most of us who play with the likes of Raspberry Pis and other SBC boards as well as other devices, have…
GPIO the Hard Way
I struggled with the title for this one as I figured if I put /sys/class/anything in the title – everyone would run away as I usually do. This entry came about because of my utter annoyance that so many little Linux SBCs out there come with ZERO or very little…
