I’m busy compiling MongoDB for the Pi and it’s going to take hours apparently – so I figured I’d give you some updates while I’m waiting. I’ve made some progress with my little ESP8266 board (ESP-12) in terms of deciding how to handle MQTT. Initially I had a bunch of…
ESP201
Many thanks to readers in here for the comments – I can’t believe how keen people are to help. Ok, so you may recall that some time ago I bought an ESP-201 board and the baseboard to with it – the whole lot was about a tenner on Ebay, a…
Webmin for Pi
A friend of mine put me onto this link tonight – a nice web admin panel for the Raspberry Pi… and no I didn’t get around to soldering the ESP-12 module – that’s a writeup for the weekend – and yes, my ESP201 module definitely does NOT have the internal…
Monday Morning at the Lab
Just in case anyone in the UK or EU is even remotely interested, I just put up my little pocket scope on Ebay. http://www.ebay.co.uk/itm/231492939705 Meanwhile talking of Ebay, the Raspberry Pi is currently working a treat on THIS little number…. a cheap WIFI dongle. http://www.ebay.co.uk/itm/331400872324 – it’s been running overnight…
Raspberry Pi WIFI
Today is going well up to now – I purchased a WIFI dongle for around £4 from EBAY, supposedly specifically for Pi (yeah right) market simply “802.11n”. Plugged it in, rebooted the Pi 2, nothing. I scoured the web and discovered you can look to see what’s happening with: dmesg…
ESP8266 MQTT and the UART
I wonder… those of you who have used the excellent MQTT software (stand-alone – not the LUA version)… I need to do two things – one of them is giving me problems but is no doubt trivial – the other I’m hoping someone has already solved. Ok, so I’m using…
FTDI Bricked Chips Fix
I odn’t know if I’ve been in a cave for the last few months – I certainly have for the last couple of weeks (literally), but when I came to program my little ESP8266 boards using the only trusty FTDI chip I have here in Spain (and as you can…
So Many Things to Do Video
I’ve been meaning to update the blog – and I just keep getting sidetracked with the many interesting possibilities of Node-Red…. so – I put a short video together here. Should be something of interest in it. https://www.youtube.com/watch?v=xoQ_Fs31xtM Pete Node-Red on The Raspberry Pi
Graphing Wonders
Tonight I’ve been building on my earlier work on graphing, if you read a few blogs back you’ll know I got some basic graphing running on the Raspberry Pi 2, taking MQTT data from a sensor and storing it in MYSQL. Well that was fine apart from the graphs having…
Pi 2 Pocket Control
Update July 2015: Hard to believe it is months since I wrote this – anyway a few of you have had trouble with this so I’m making some changes. Those of you who’ve been following my exploits for some time will know that initially I started using Arduino to control…
Pi Graphing Progress
Making great progress with the Raspberry Pi despite not knowing Linux from a hole in the ground a week ago. We’re at our place in Spain for a short break with limited facilities (I’ve ordered a USB scope for the next time we’re here). As of this morning, I’ve managed…
Node-Red Strangeness
THIS ONE HAS BEEN SOLVED – SEE “SOLUTION”. I freely admit to being utterly stumped. Having spent the day getting node-red on the Blackberry Pi2 I’ve made this simple page… an MQTT message coming in is passed out… and also goes to GPIO 0. This works – send a 1…
apt-get WHAT?
If like me you are a reluctant Linux user, dragged in merely because you want to make use of the new Raspberry Pi 2 in your projects (and I bought mine as a hub for my Arduino/ESP8266 projects) – you’ll be slowly coming to grips with meaningful terms like SUDO…
NodeMCU Broken?
For now I’m concentrating on achieving reliability with MQTT using the original library and C – and interfacing it to the likes of the Raspberry Pi 2, but it came to my attention for those of you using Lua right now that there seems to be a problem with the…
Domain Issues on Pi 2
So a little while ago, one of you helpful people in here gave me a tip when my Raspberry Pi 2 based CRON JOB started up and failed to send emails. I added MAILTO: pete@scargill.org to whatever I was working on and lo and behold the emails worked. But now…
Pi 2 Memory Boost
Or: How to get back that missing quarter gigabyte of RAM. I must admit, though I’m very pleased with my new Raspberry Pi as a potential controller for my various Arduino and ESP8266 boards, I was a bit bemused given the claim of 1GB of main memory to realise on…
Enter Bluefish for Pi and PC
If you’ve read my blog you will know I have a near pathological aversion to the command line – reminds me too much of DOS and the 90s. So when I got my new spiffy Raspberry Pi 2 (which I am really impressed with and which will almost definitely form…
Thanks
Just a quick note to those of you who come in here, are constructive and offer help and hopefully sometimes take away information… thanks for taking the time – and thanks for putting up with the name change of the blog – which got me away from reliance on WordPress.com. …
Cloud Security
Cloud security is as likely not something the average Internet of Things enthusiast thinks about on a daily basis but here we all are, embarking on a future where our houses and perhaps offices will be connected to the Internet to a degree never seen before. Many are already connected…
Flashing Lights on Raspberry Pi 2
So – having managed to get WordPress up and running on the P2 I thought it might be nice to step back toward the original plan and get some home control running. I like PHP so I thought that it might be nice to have a PHP page with some…
