  • Custom Piano Tickles the Ivories

    This electronic keyboard is completely designed and built from scratch, including the structure of the instrument and the keys themselves. [Balthasar] made each one by hand out of wood and then built an action mechanism for them to register presses. While they don’t detect velocity or pressure, the instrument is capable of defining the waveform and envelope for any note, is able to play multiple notes per key, and is able to change individual octaves. This is thanks to a custom 6×12 matrix connected to a STM32 microcontroller. Part of the reason [Balthasar] chose this microcontroller is that it can do some of the calculations needed to produce music in a single clock cycle, which is an impressive and under-reported feature for the platform.

  • Hacking A Proper Dash Into The Tesla Model 3 | Hackaday

    The build relies on a CANserver, an ESP32-based device specifically built for hooking up to the CAN bus on Tesla vehicles and sharing the data externally. The data can then be piped wirelessly to an Android phone running CANdash to display all the desired information. With the help of an aftermarket dash clip or a 3D printed custom mount, the phone can then be placed behind the steering wheel to display data in the usual location.

  • Firefox Nightly: These Weeks in Firefox: Issue 108
  • Celebrating Data Privacy Day

    Happy International Data Privacy Day! While January 28 marks a day to raise awareness and promote best practices for privacy and data protection around the world, we at Mozilla do this work year-round so our users can celebrate today — and every day — the endless joy the internet has to offer.

    We know that data privacy can feel daunting, and the truth is, no one is perfect when it comes to protecting their data 24/7. At Mozilla though, we want to make data protection feel a bit easier and not like something else on the never-ending life to-do list. We build products that protect people online so they can experience the best of the web without compromising on privacy, performance or convenience. The internet is too good to miss out on — we’ll take care of securing it so you can focus on exploring and enjoying it.

    To accomplish this, we started with square one: our Firefox browser — enhancing its privacy and tracking protections over the past year, while improving its user experience to make surfing the web less dangerous and more carefree.

    Despite how it sounds, you don’t need to be a hacker to make use of an encrypted connection. Whether you’re online shopping or want to make sure your login credentials are safe from attackers, we’re working on ensuring your browsing experience is secure from start to finish. That’s why, when you open up a Private Browsing tab on Firefox, you can be confident that your information is safe thanks to our HTTPS by Default offering, which ensures the data you share with and receive from a website is encrypted and won’t be able to be intercepted, viewed or tampered with by a hacker. To take this one step further, we’re also working with Internet Service Providers like Comcast and other partners through our Trusted Recursive Resolver program, to begin making DNS encryption the default for Firefox users in the US and Canada.

  • Abuse & Sex Crimes at FOSDEM and Open Source tech events

    All these people have conflicts of interest. For example, Molly herself was secretly sleeping with Chris Lamb when he was leader of Debian. Imagine a woman comes to Molly's team to make an abuse complaint about Lamb or one of his close friends.

    [...]

    Women trusting women simply because they are women is not a good choice.

    There are numerous examples of women like Molly who have been sympathetic to or even in cahoots with male abusers.

  • What is MongoDB, and how does it work? | FOSS Linux

    MongoDB is the most common and widely used NoSQL database. It is an open-source document-oriented DB. NoSQL is used to refer to ‘non-relational’. This means that the MongoDB database is not based on tabular relations like RDBMS as it provides a distinct storage and data retrieval mechanism.

    The storage format employed by MongoDB is referred to as BSON. The database is maintained by MongoDB Inc. and is licensed under the Server-Side Public License (SSPL).

So, what if you can convert your system to a Linux-powered retro gaming console using a distribution? Read more

Bambu Lab X1 - A color 3D Printer with LIDAR and AI for improved accuracy, ease of use (Crowdfunding)

3D printing can be time-consuming and challenging, and even today, it’s still not as easy as using a photocopier, but the team at Bambu Lab has taken it upon itself to make a better, easier-to-use 3D printer with the X1 color 3D printer combining LIDAR and AI technology to level the bed, calibrate the prints, and detect anomalies. The Bambu Lab X1 3D printer supports up to 16 colors, is making removing support easier with snap-away material or dissolvable filament, can handle PC and PA-CF filaments beyond the traditional PLA and PETG filaments, manage up to 500 mm/s prints, and provides better prints with features such as active vibration compensation. Oh, and you don’t need to assemble it, since it comes fully assembled and ready to use out of the box. Read more
