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

May 29, 2017August 19, 2017 Peter ScargillAdafruit, General, Python18 Comments on 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

May 27, 2017September 30, 2017 Peter ScargillGeneral12 Comments on 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

May 21, 2017December 23, 2018 Peter ScargillFriendlyArm, K272 Comments on 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

May 19, 2017June 13, 2017 Peter ScargillFriendlyArm, Neo, Neo214 Comments on 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

May 18, 2017June 13, 2017 Peter ScargillGeneral, nextion19 Comments on 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

May 16, 2017June 13, 2017 Peter Scargillhighcharts, node-red, node-red-dashboard, plotly6 Comments on 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

May 10, 2017June 13, 2017 Peter ScargillESP8266, ESP8266 SDK, home control32 Comments on 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

May 7, 2017July 23, 2017 Peter ScargillLithium148 Comments on 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

May 6, 2017June 13, 2017 Peter Scargillgpio20 Comments on 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…

Cheap NodeMCU Boards

May 2, 2017June 13, 2017 Peter ScargillESP8266, nodeMCU32 Comments on Cheap NodeMCU Boards

This could be the shorted blog I’ve ever written! We’ve been talking about ESP8266 recently and as I was running out of boards, I sent off for some of these from AliExpress – my favourite store next to Ebay.  At a total cost of just over £3 they had to…

Thoughts on RAM

May 2, 2017 Peter ScargillFriendlyArm, Log2RAM, power supplies, RamDisk, ramlog, Raspberry Pi36 Comments on Thoughts on RAM

These are just thoughts – hopefully someone is going to write in and tell me I have it all wrong. As regular readers will know I have reviewed (and messed with) MANY small Pi-type boards including the Raspberry Pi, Banana Pi, NanoPi etc etc.  I’ve also had a go with…

ESP32 First Steps

May 1, 2017May 2, 2017 Peter ScargillESP3238 Comments on ESP32 First Steps

I said I would not touch the ESP32 until the price came down and true to form, I just received my first ESP32 from AliExpress. Still a little more expensive than I’d like at £5.35 (inc postage came to £6.67) but I felt it was time to make a start.…
