Patrik Thalin writes: This device is installed in my home to monitor the usage of electricity. It counts the pulses from the meter and produces a log file with number of pulses and a time stamp that can later be analyzed. The hardware is quite simple. The NodeMCU development kit board with an ESP8266 running […]

WIFI-based appliance module using the ESP8266 (ESP12) and a latching relay
Steve writes, “This is an WIFI-based appliance module using the ESP8266 (ESP12) and a latching relay. The appliance module is powered from the AC line using an inexpensive 5V 1AMP universal input power supply which is attached to the board. There are provisions for local control using a pushbutton switch, and there is an option […]
Dual port serial terminal
Piotr writes, “When developing communication between Arduino and ESP8266, I wanted to spy both lines of serial port. I was unable to find the right program on the web, so I made one myself.” The task is simple. I want to the spy serial communication at both lines at the same time. The hardware is […]

@PixelatedPic tweeted, “IoT with ESP8266 + NodeMCU firmware and couple of Lua :) its alive!”
ESP8266 Wifi information LCD
Renze shares his ESP8266 Wifi information LCD in the project log forum: This is a little project I did in about 2 hours. It uses an LCD display I got from an old ISDN phone and shows text sent to it over WiFi. The ESP8266 runs a webserver which shows a form that can be used to […]
Graphic equalizer display using ESP8266-12, MSGEQ7 and WS2812
Amir Avni made a graphic equalizer display using ESP8266-12, MSGEQ7 and WS2812: Finally, I’ve created a this project: An equalizer display controlled by ESP8266 with the NodeMCU firmware, where the equalizer colors are controlled via WiFi Project info at whatimadetoday site. Check out the video after the break.
ESP8266 relay board

DIY ESP8266 Development Board
A DIY ESP8266 Development Board from Electro-Labs: In this project, we are building an ESP8266 Development Board which lets the user make connection to ESP8266 from a PIC microcontroller and a PC. The board also provides all the needs to be used as microcontroller peripherals such as LCD display, pusbuttons, indicator LEDs and GPIO extension. The PC […]
ESP8266 WiFi LED dimmer Part 8 of X: Version 2 of the PCB design
Quindor blogged about his ESP8266 WiFi LED dimmer project with DirtyPCBs: With the help of kind internet folks I was able to get a fritzing part for the new voltage converter I wanted to use to try and make a smaller board. A few weeks ago I sent my new ‘panalized’ design to dirtypcb’s and I got […]
Use ESP8266 module as a wireless switcher
Razvan Dubau over at Extragsm posted a how-to on using an ESP8266 module as a wireless switcher: A custom firmware to transform the ESP8266 wifi module into a wifi http based switcher GPIO02 is used as an output pin. You can connect a led or a relay and controll it by a button added to GPIO00. Also the […]
Home Control 2015
Peter Scargill writes: If you’ve read my early blogs you’ll know I do a lot of work with a pal of mine, Aidan Ruff. We had an R&D company for years and one of our products was a home control system which was plastered all over the UK tech press at the time and loads […]
ESP8266: Arduino compatible $5 MCU with WiFi
MAKE has posted Alasdair Allan’s three part series concerning the ESP8266 MCU. Alasdair highlights the capabilities and limitations of this chip, the installation and use of a supporting version of the Arduino IDE, and how to create a breadboard adapter for the ESP-01 breakout board (pictured above.) Via MAKE.
Introducing ESPToy 1.2 (with Lua Firmware)
Ray Wang from RaysHobby has written an article on his ESPToy 1.2, a ESP8266 development board based on the Lua firmware: A little while back I released the very first version of ESPToy — a ESP8266 Development Board with a few useful on-board components like color LED, button, and temperature sensor. It has a built-in […]
ESP8266 running NodeMCU as a controller
jscottb over at LetsMakeRobots writes: My goal for this mini project is to create A simple autonomous rover with just the ESP and NodeMCU. In looking at the specs for node most of the supporting libraries already written. GPIO, PWM and Timer libraries are included in the Lua interpreter. After flashing the board my next up […]
Arduino IDE released for ESP8266
Richard over at ESP8266 CommunityForum writes, “I have setup a new section for ESP8266 Arduino as IGRR and myself have successfully ported the Arduino IDE over to the ESP8266 and have it all working very nicely now. ESP8266 Arduino and the code is on github, we have also set up a compilation server and executables will also […]
ESP-03 modules with the Bus Pirate
Tim Jagenberg writes: Today I received the ESP-03 modules I had ordered from Shanghai. A nice little breakout for the ESP8266EX with ceramic antenna. Due to the 2mm spacing between the contacts on the sides, I had to bend the headers into shape before soldering them to the module. As an initial function test I used […]
WiFi thermostat with weekly scheduler
A WiFi thermostat with weekly scheduler project by Martin Harizanov: As additional feature, I’ve added thermostat function based on Trystan Lea’s Open Thermostat Scheduler, only my code runs entirely off the ESP8266 SoC. The UI is touch-friendly and works great on mobile devices I’ve also added broadcasting functionality, allowing the board to send its state to third […]
