MQTT LED Matrix Display

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 have an LED display at home and that means FUN. LED displays are cool. Your team’s score, your number in the IRS queue, the estimated arrival time for your next commute,… Now that TVs are replacing LED displays (like the later did with the electromechanical ones) they have acquire an almost vintage-status....

Rentalito goes Spark Core

The Rentalito is a never ending project. It began as a funny project at work using an Arduino UNO and an Ethernet Shield, then it got rid of some cables by using a Roving Networks RN-XV WIFI module, after that it supported MQTT by implementing Nick O’Leary’s PubSubClient library and now it leaves the well known Arduino hardware to embrace the powerful Spark Core board. Spark Core powered Rentalito - prototype Spark Core The Spark Core is a development board based on the STM32F103CB, an ARM 32-bit Cortex M3 microcontroller by ST Microelectronics, that integrates Texas Instruments CC3000 WIFI module....
