  • Detect vandalism using audio classification on the Nano 33 BLE Sense
    by Arduino Team on 1 December 2022 at 20:36

    Having something broken into and/or destroyed is an act that most people hope to avoid altogether or at least catch the perpetrator in the act when it does occur. And as Nekhil R. notes in his project write-up, traditional deterrence/detection methods often fail, meaning that a newer type of solution was necessary. Unlike other glass The post Detect vandalism using audio classification on the Nano 33 BLE Sense appeared first on Arduino Blog.

  • Binbot 9000 moves to where the trash is
    by Arduino Team on 1 December 2022 at 20:13

    Our modern societies create a lot of garbage, which we can fortunately remove from our homes thanks to local waste management services. But the garbage people won’t come sift through your house for refuse, which forces you to utilize trash bins. Those bins never seem to be nearby when you need them, which is why The post Binbot 9000 moves to where the trash is appeared first on Arduino Blog.

  • This health belt can provide early warning of heart failure
    by Arduino Team on 30 November 2022 at 20:07

    Heart disease is the most common cause of death — not just in industrialized countries, but for the world as a whole. Many deaths caused by heart failure could be prevented if the patient received medical care sooner, but people are often unaware of impending heart failure until it actually occurs. However, there are physiological The post This health belt can provide early warning of heart failure appeared first on Arduino Blog.

  • Fully automated desktop weaving machine controlled by Arduino
    by Arduino Team on 29 November 2022 at 19:31

    Automated weaving machines are one of the most important (and underappreciated) advancements to come from the industrial revolution. Prior to their invention, most people only owned a few garments that were woven and maintained by the family. With the introduction of machines able to churn out textiles, affordable clothing suddenly became available.

    Peter Balch visited a robot exhibit at his local museum and noticed that one of the most popular pieces was a robot head that would track and mimic visitors’ faces. That was so interesting that Balch decided to replicate the project in order to learn how it was done. To do that, he first needed The post This skull-like android head was made to mimic human expressions appeared first on Arduino Blog.

  • See how Ben Eater reverse engineered an ’80s TV-censoring device
    by Arduino Team on 28 November 2022 at 14:55

    Back in the 1980s, there existed a piece of hardware called the “TVGuardian,” which would attempt to censor incoming video in real-time. As recently covered by the wonderful YouTube channel Technology Connections, the TVGuardian reads captioning data as it’s sent and then replaces the bad word(s) with an alternative phrase and also mutes the audio.

Instead, this new version would closely mimic the layout and functionality of an actual Formula 1 wheel, complete with all of the The post Wesley Kagan’s PorscheKart project returns with a new Arduino-powered F1 steering wheel appeared first on Arduino Blog.

  • Designing a 3D-printed EMG bionic hand as a low-cost alternative to prosthetic limbs
    by Arduino Team on 25 November 2022 at 19:52

    The cost of a new prosthetic arm can range from several thousand dollars to tens of thousands, putting them out of reach for many people. Ahmad Ikram recognized this need and decided to design and build a far cheaper, open source version that has myoelectric capabilities. To begin this project, Ikram decided upon using the InMoov 3D-printed arm The post Designing a 3D-printed EMG bionic hand as a low-cost alternative to prosthetic limbs appeared first on Arduino Blog.
