July 31, 2016April 9, 2017 Peter ScargillArduino, ESP12, ESP12E, ESP12F, ESP8266, i2c, LCD, OLED59 Comments on I2C Continuum

Updated August 07. 2016: This article which started off discussing the “new addition” of i2c to the home control software, is now NOT ONLY about an I2c  2/4 line LCD display facility recently added to the ESP8266 boards – but there’s a PARALLEL version as well, making use of GPIO…

Node-Red on a Phone

July 30, 2016July 31, 2016 Peter ScargillNode, Node Red, node-red, node-red-dashboard, node.js37 Comments on Node-Red on a Phone

I have to hand ALL the credit to Dave at the Node-Red Google Groups for this – and you might want to pop any questions in that direction because I know even less about running Android at the command prompt than I do Debian! Running Node-Red on your Android phone…

I2C Conundrums

July 28, 2016July 28, 2016 Peter Scargilli2c52 Comments on I2C Conundrums

Resolved  – working though still don’t know why Arduino single write was causing problems – however – got a way around it. Firstly why am I doing this i2c thing? Well, the little ESP8266 is a wonderful thing but there are some chips out there that are really neat and…

Node Red Dashboard

July 27, 2016July 27, 2016 Peter Scargillnode-red, node-red-dashboard25 Comments on Node Red Dashboard

As regular readers and fans of node-red will know, I’ve been a fan of node-red-contrib-ui for some time – I wrote about adding security to it some time ago and until Imperihome came to my attention I was developing pages based on this.  But, sadly the fellow developing it ran…

WIFI Smart Socket

July 18, 2016 Peter Scargillitead, sonoff, wall socket, wifi wall socket36 Comments on WIFI Smart Socket

It looks like Itead have done it again – another winner – well that’s all down to the price and I’ll leave you to look that one up…the site says £9.76 for the unit which is reasonable – but I didn’t check postage. The first modern WIFI wall socket I…

ESP8266 Meets Arduino via I2C

July 17, 2016 Peter Scargill1284, Arduino, ESP-12, ESP-12E, ESP-12F, ESP82662 Comments on ESP8266 Meets Arduino via I2C

If you’ve been reading the blog regularly you’ll know I added I2c to the ESP8266 code some time ago – that is, the ability to send an I2c message either to read or write – originally intended and still working with cheap I/O expanders – so you lose 2 wires…

Sunday Morning Experimenting

July 17, 2016July 17, 2016 Peter ScargillESP32, ESP8266, i2c21 Comments on Sunday Morning Experimenting

I figured after a couple of horrendous days figuring out what was wrong with my ROMS, it was time for a morning’s relaxing.  Some time ago I added I2c to the Home Control software but never actually got around to doing anything with it.  The i2c parallel expansion modules I…

ESP SDK and RBoot Woes

July 16, 2016July 17, 2016 Peter ScargillGeneral20 Comments on ESP SDK and RBoot Woes

Remember I did an article entitles Serial Woes? Well that’s been changed to serial success as we found bugs in tools and gained an understanding of the USB FTDI handshaking lines – which altogether led to improvements in the Node-Red Arduino node and a completely working solution for USB Serial…

NanoPi M2

July 15, 2016 Peter ScargillUncategorized5 Comments on NanoPi M2

More from FriendlyArm – this time the NanoPi M2.  I’ve had this board running both Debian and Android – but first – a little about the boards. Like the M1 these are small – around 65mm by 60mm so much smaller than Raspberry Pi. They are also cheaper than the…

Raspberry Pi Node Red Serial Delight

July 15, 2016September 23, 2016 Peter ScargillRaspberry Pi 237 Comments on Raspberry Pi Node Red Serial Delight

Or – how to get USB serial ports working on the Raspberry Pi This originally was a cry for help – I wanted a second serial port on the Raspberry Pi AND I made the mistake of trying out Firmata on the Arduino at the same time – resulting collection…

Apologies if you’ve been checking the blog today and noticed it appear in a smorgasbord of colour. I’ve been trying to fix an issue with login and menus – and in the end, started from scratch. Hopefully now all is working well.  This all started with a note to ask…

A Good Gadget Day

July 9, 2016October 10, 2020 Peter ScargillESP826621 Comments on A Good Gadget Day

Today has been a good day. After a great Saturday down at Castril (waterfalls etc – fantastic weather) in Southern Spain, Aidan Ruff and I sat down with some wine to test his new movement sensor/smoke detector board. As is often the case, the first iteration has some issues but…

Home Control Updates

July 8, 2016 Peter ScargillESP-12, ESP8266, home control6 Comments on Home Control Updates

For those following the home control project including the ROMS for ESP8266, I’ve made several changes in the last few days including a new uptime command {uptime?} returning a string of the time since last reset/power-cycle. Also added that to the debug output – also fixed a couple of minor…

Lua Revisited

July 8, 2016July 11, 2016 Peter ScargillnodeMCU12 Comments on Lua Revisited

I like to revisit things I’ve looked at in the past just to see if anything has changed. And so it was that I went off to the NODEMCU site to take a look at how it is coming on. NodeMCU is software for the ESP8266 which runs an interpreted…

32Mb ESP01 and Sonoff

July 6, 2016July 11, 2016 Peter ScargillESP-01, sonoff68 Comments on 32Mb ESP01 and Sonoff

Some time ago I passed comment in here about converting an ESP-01 to 32Mb  (or 4MB).  And here it is in the flesh – a 32Mb ESP-01 – and also – at last – Sonoff Upgrades. Now, why would you want to do all of that? I would suggest only…

A5 V11 Router

July 4, 2016July 7, 2016 Peter Scargillmodem, MQTT, router64 Comments on A5 V11 Router

Or – the cheapest router on the planet – probably. I should say at the outset this experiment did not end too well – currently waiting for another unit to arrive – but worth a read in case you’re about to embark on using this unit. I had to pick…
