    Arduino Yùn Rev.2 is here!

    Massimo Banzi — March 29th, 2018

    Since its launch in 2013, the Yùn–a small Linux machine and a microcontroller in a small Arduino form factor–found its way into hundreds of thousands of projects and professional applications. Last year, we decided that it was time for a refresh and began working hard to develop a true open-source design, with more compelling features and better overall software support.

    The new board, which is expected to hit the market in the second half of April, will include enhanced functionality and compatibility with its predecessor.

    Why a New Yùn

    The Yùn enjoyed tremendous success; however, it ended up being affected by the internal issues we dealt with over the past couple of years and support has been quite intermittent.

    For example, the board was never really an open-source product and the software had some challenges that we wanted to fix, especially from a security point of view.

    What’s New in Rev.2

    Hardware:  

    • Much better, more robust power supply
    • New Ethernet connector with a clever mounting solution that enables the use of all possible shields with no risk for accidental short circuits
    • Horizontal USB connector to save vertical space
    • Improved USB hub

    Software: 

    • Software stack updated to OpenWRT latest version, including all patches
    • SSL support on the bridge Arduino / Linux bridge

    Yùn Rev.2 is scheduled to begin shipping in April. Until then, you can stay up-to-date by clicking “NOTIFY ME” on our store.

    Let an Arduino notify you when the coffee is ready

    Arduino Team — February 23rd, 2018

    Hacker “wesgood,” apparently not satisfied with randomly checking the office coffee pot to see if a fresh brew was available, decided to make his own notification system.

    His device uses a current sensor to monitor power usage of the coffee pot, and after some observation, he was able to pick out its brewing pattern—7A at 10 minutes, then quick cycling to keep the pot warm.

    The system features an Arduino Yún for brew tracking and sends an alert via his office communication tool to let everyone know that a fresh pot is ready. As with many projects, the first iteration started life on a breadboard, but now exists on a manufactured PCB as a shield. It even has a second channel that is slated for use with the office kettle.

    Once the Arduino side of the Yún detects the brew cycle is complete, it triggers a shell script under Linux that sends a notification to our office communication tool Hipchat. It also records the data about date and cycle stage so that Hipchat can query the database (on a webserver) and request things like what stage the brew cycle is on and when it brewed last.

    You can find additional build details on Imgur.
