Lingan SWA1 Plug in Wi-Fi Socket with MQTT (ESP8266)

This is another cheap plug in Wi-Fi mains socket that uses the ESP8266, comparable to the Sonoff S20. Cost was £8.34 + £2.34 shipping to the UK from TVC-Mall. It is also available from Banggood for a little more and is starting to show up on eBay now too. I didn’t try the standard software/firmware […]

Ai-Light RGBW LED Wi-Fi Light Bulbs with MQTT (ESP8266)

I already had most of my lights converted to RGBW but couldn’t resist getting one of these when I heard they contained the ESP8266 and could be reprogrammed, I eventually ended up with three after buying a second to verify the first was not at fault and then a third to check it was the […]

H801 Wi-Fi RGBW LED Controller with MQTT (ESP8266)

I picked a couple of these up from Aliexpress earlier in the year, I had been planning to DIY something similar but when I spotted these Aiboo H801 RGBWW units for only £8.35 each there didn’t seem much point.  They support the three RGB channels as well as two white channels, up to 96W per channel and […]

Itead Sonoff S20 Plug In Wi-Fi Sockets with MQTT (ESP8266)

Itead have expanded their Sonoff range a lot since I wrote about the original Sonoff module over a year ago. That module has been in use since then and has been rock solid although I did switch from the ESPEasy firmware to Theo Arends’ Sonoff specific firmware, now called TASMOTA which has seen a lot of development. […]

ESP8266 Relay Modules from Itead and Electrodragon

Here are two similar but also rather different WiFi controlled mains switching relay modules that both use the ESP8266 WiFi SoC. Both come with a nice case, can be reprogrammed with your own firmware and are exceedingly cheap for what you get. I’m using these with MQTT and Node-RED so that they seamlessly integrate with the […]

Orvibo S20 WiFi Mains Socket with Node-RED

For years I used X10 for all my remote controlled sockets but the unreliability eventually drove me to RF based sockets, the Home Easy ones in particular as you can’t beat the price, often available for circa £20 for a pack of 3 with a remote control and easily integrated into Node-RED and the likes with […]

Background Radiation Monitoring

A little Saturday afternoon project last weekend was putting together this geiger counter kit from RH Electronics in Israel, paired with a soviet SBM-20 Geiger-Müller tube sourced from an eBay seller in the Ukraine. Total cost was £32 which seems very reasonable to me. The RH Electronics kit comes with all the components apart from the […]

3D Printed Cases For TinyTX and Tiny328

Another post I’ve been meaning to write for a long time. I finally got my Rigidbot 3D printer in August 2014 some 9 months later than the estimate but I was one of the lucky ones, many had to wait a lot longer and some have even had to pay extra for delivery, having already paid it once as the company […]
