jeelabs @ github.com has written a firmware for ESP8266 that enables it to talk to RS232 of your mcu via WiFi and also programm your mcu via WiFi. He writes: This firmware connects an attached micro-controller to the internet using a ESP8266 Wifi module. It implements a number of features: transparent bridge between Wifi and […]
Sit.Up – alerts the user if sitting to long
https://www.electronics-lab.com/sit-up-alerts-the-user-if-sitting-to-long/
electrobob.com has build a device that alerts you if sitting to long: Sitting for long periods has become more common in today’s jobs causing serious health issues. Unfortunately the plethora of activity trackers fail to address the issue: being rather active while sitting does not provide a good picture of the amount of time spent […]

https://www.electronics-lab.com/esp8266-touchscreen-wifi-light-controller-and-clock/
Spiros Papadimitriou has build a WiFi light controller and clock based on ESP8266: A couple of months ago I picked up cheap WiFi-controlled LED bulbs (one among dozens of very similar devices), after seeing them at a friend’s place. This turned out to be an excuse to play with the ESP8266, which has inspired several […]

How to Make Two ESP8266 Talk
https://www.electronics-lab.com/how-to-make-two-esp8266-talk/
Rui Santos shows us how to make two ESP8266 to talk: In this project you’re going to make two ESP8266 talk with each other. How it works? You’re going to set one ESP as an Access Point (Server) and another ESP as a Station (Client). Then they’ll establish a wireless communication and the Client sends […]

Horacio Bouzas published a 4 way WiFi antenna switch: I started playing with electronics back when I was 10 years old in Argentina, where I grew up. Then I got my ham radio operator license when I was 16 years old and I was very active in the ham club and on the air. It […]
How to Control Your ESP8266 From Anywhere in the World
https://www.electronics-lab.com/how-to-control-your-esp8266-from-anywhere-in-the-world/
by Rui Santos @ randomnerdtutorials.com: The most common questions I get about the ESP8266 WiFi Modules are: “Is it possible to control my ESP8266 from anywhere in the world?” and “How can I control my ESP8266 from anywhere?”. I’m happy to announce today that I have a solution for that problem. With the new version of […]
WiFi smoke detector
https://www.electronics-lab.com/wifi-smoke-detector/
by Proto G @ instructables.com: This is a simple WiFI Smoke Detector that texts me when it senses smoke. I made this for my battery storage area in case of a lithium polymer fire. I still have all of my regular smoke detectors installed and I don’t suggest relying only on this, but rather as […]
ESP8266 MQTT battery monitor project
https://www.electronics-lab.com/esp8266-mqtt-battery-monitor-project/
Steve’s latest project, a wireless MQTT battery monitor: This board uses an ESP8266 (ESP12), a Texas Instruments INA226 I2C voltage and current monitor, and a Texas Instruments LMR12010X buck converter. This board is designed to wirelessly monitor 12 volt batteries and power supplies using an external current shunt resistor. The voltage across the shunt resistor […]
