Espressif Leaks RISC-V Powered ESP8266 Pin-Compatible ESP32-C3
https://www.electronics-lab.com/espressif-leaks-risc-v-powered-esp8266-pin-compatible-esp32-c3/
The ESP32-C3 is a WiFi SoC that contains a RISC-V core in place of the Tensilica core in the ESP32 we are all familiar with. It uses the ESP8266 pin-out. As with other ESP32 family members, this one delivers b/g/n WiFi and Bluetooth LE 5, where it differs is the RISC-V 32 Single-core processor with […]

Have you ever wanted an indicator of how much the internet is being used at a particular time? You may want to know if your roomies are making it too slow for you to use, or just for the sole purpose of fun. For some reason, the router manufacturers usually do not include an indicator […]
Wifi Gate Controller is Arduino Compatible

After years of using weak garage door openers and trying to position them just right so my solar powered gate 400′ away would open when needed I decided it was time to make a wireless controller of my own. 802.11 is a ubiquitous choice and with the right antenna range is not a problem. Two […]
Wireless SD Card Reader using ESP8266
https://www.electronics-lab.com/wireless-sd-card-reader/
One of the good things about being a maker is the power it gives you to create your own stuff. Believing USB devices have not lived up to their designation of truly being universal and working irrespective of the kind of ports they are plugged into, Hackaday user, Neutrino, recently embarked on a mission to […]
Top 10 Popular Microcontrollers Among Makers
https://www.electronics-lab.com/top-10-popular-microcontrollers-among-makers/
At the heart of any embedded electronics device, either on a DIY or professional product level is a microcontroller. They run the codes/firmware that helps developers obtain inputs from sensors and tie it to actions executed through actuators. While they are usually developed as general-purpose components, MCUs are built with certain features and functionalities that […]
Masterkey – USB WiFi Keylogger
https://www.electronics-lab.com/masterkey-usb-wifi-keylogger/
A Keylogger, a short form for keystroke logger, is a type of monitoring or digital surveillance tool (software or hardware) that is primarily used to record (log) keyboard keystrokes made by the user of the host computer. They are more advanced in recent times and are sometimes also used to log mouse clicks, touches, etc., […]
Elektor Article: DCF77 Emulator with ESP8266
https://www.electronics-lab.com/elektor-article-dcf77-emulator-esp8266/
Replace over-air time by Internet time About twenty years ago I recycled and modernised a vintage clock with Nixie tubes built by my father in the nineteen seventies. I replaced the digital logic by a microcontroller and used a DCF77 receiver module instead of the original 50-Hz derived timebase. Over many years the clock has […]

This is an ESP8266 based coronavirus tracking project from “Volkan Unal” on github.com. The tracker can be configured to display the details of your own country. Instructions 1- Change your wifi information from WifiConnect.h file char ssid[32] = "yourssid"; char password[64] = "yourpass"; 2- Define your country code from corona.ino file #define country_code "yourcountrycode" GET […]
Temper: Sleek temperature sensor built on ESP8266
https://www.electronics-lab.com/temper-sleek-temperature-sensor-built-esp8266/
Meet Temper, a compact, low power temperature sensor based on ESP8266 and SHT30 with a large 13×7 pixel led display. It accesses WiFi periodically to display temperature and humidity data as well as battery percentage via the MQTT protocol. The device’s display uses three 74HC595 + 7 n-fets, TP4054 to handle battery charging through a […]
Network Clock using ESP8266 and OLED display
https://www.electronics-lab.com/network-clock-using-esp8266-oled-display/
There are several situations where using an RTC could adversely affect your project by increasing cost, size, time accuracy or IO requirements. To prevent this, especially in ESP/WiFi-based or other clock-reliant projects, makers usually turn to obtain time information from NTP servers. I recently came across a project by BitsandBlobs which used standalone NTP Servers […]
