BJ is a musician, singer, and composer, and has written the bulk of the theme music you hear on National Public Radio (NPR). His music is hard […]

      African elephants need a lot of water every day for drinking and mud baths . During the dry season, their keen sense of smell allows them to detect water underground in dry riverbeds, where they dig holes with their tusks to reach it. Once the elephants have had their fill, other animals move in to […]
    • S[w]@G: Smart Wicked Aquaponics Garden October 5, 2017
      so I’m building Bostons 1st Kijani Grows 35gallon Wicked Smart aquaponics garden… lets just call it “swag” for short. Swag is definitely getting customized a tad, mostly because it will be both our indoor home garden & transportable demo garden. This means it has to be a bit more rigid to withstand all the vibration […]

      Uchi Mata is considered the “Throw of Kings” and made my good friend Chuma Soita invincible in competitive judo.

      When tasked with converting an antique pump organ—sort of a miniature version of a full-sized pipe organ—into part of an escape room puzzle, hacker Alec Smecher decided to turn it into a vocal MIDI device. To accomplish this, he embedded switches in each of the keys, then wired them into an Arduino Leonardo embedded in the 100-year-old […]

    • Be among the first to try the Arduino IDE 1.9 Beta October 11, 2017
      Today we’re very excited (and a bit nervous) to announce the new development cycle of the Arduino IDE. As you may have noticed, we’ve been continuously removing functionality from the Java package, and migrating them to a collection of external tools.
