Neon Pixels Matrix Display Clock
https://www.electronics-lab.com/neon-pixels-matrix-display-clock/
Pierre @pierremuth.wordpress.com shares his latest project with us. It’s a neon lamp dot matrix clock based on INS-1 tubes. He writes: As a big enthusiast of glowing neon, I had to do something with the INS-1 (ИНC-1) tubes. Disclaimer: this project is inefficient in many aspects, fortunately plenty of time was available during the 2020 […]

64×16 MQTT LED Matrix Display
https://www.electronics-lab.com/64x16-mqtt-led-matrix-display/
Xose Pérez @ tinkerman.cat build a MQTT LED matrix display to get notification messages. My MQTT network at home moves up and down a lot of messages: sensor values, triggers, notifications, device statuses,… I use Node-RED to forward the important ones to PushOver and some others to a Blynk application. But I also happen to […]

https://www.electronics-lab.com/16x32-rgb-matrix-panel-driver-arduino-shield/
Raj @ embedded-lab.com has revised his RGB Matrix Display Shield to an improved version. The shield now also carries the DS1307 RTC chip on board along with a CR1220 coin cell battery holder on the back. It is applicable for driving popular 16×32 RGB matrix panels with HUB75 (8×2 IDC) connectors. Row and column driver circuits are […]
ESP8266 Wifi enabled 8×64 pixel LED matrix display
https://www.electronics-lab.com/esp8266-wifi-enabled-8x64-pixel-led-matrix-display/
Raj @ embedded-lab.com build an ESP8266 based led matrix display. This matrix is a modification of his previous bluetooth version and uses an ESP8266 as a web server to setup the display message. No other microcontroller is used to control the display so things are kept simple and easy to build your own. This project […]
