  • Anbox on the Librem 5

  • Optical drive plays large wooden discs

    Optical media normally contains information in the form of 1s and 0s that are much too small to be seen by the human eye. This can make understanding their operation less than straightforward. To solve this problem, Jon Bumstead constructed an Arduino Nano-controlled player that uses wooden discs, with holes and solid sections large enough to clearly show what’s going on.

  • KAUDA is a low-cost, highly-efficient robotic arm

    Would you like your own industrial robot arm, but don’t have tens of thousands of dollars to spend? You could instead build Giovanni Lerda’s KAUDA, a five-axis device that uses under 800g of PLA, an Arduino Mega, and other off-the-shelf parts.

    KAUDA utilizes servos to actuate the two wrist joints, along with a NEMA 17 motor for the elbow. A single stepper rotates the base in the horizontal direction, while dual steppers provide lifting force at this joint.

    The gripper is a three-fingered linkage assembly, controlled by a small DC motor. The arm’s construction is outlined on its official website, and instructions can be found in Lerda’s write-up here. As seen in the video below, KAUDA looks great and appears to work quite well!

  • GNU Taler operational at Bern University of Applied Sciences

The system is expected to expand to allow payments at other places in the future. Various faculty members and students are involved various aspects of the project. Students interested in working on projects or theses related to the subject should contact Prof. Grothoff.

Single Points of Failure and Proprietary Entrapment (Microsoft GitHub)

  • Ahmad Haghighi: GitLab blocked Iranians’ access.

    On 3rd Oct. 2020 GitLab blocked Iranians’ access (based on IP) without any prior notice! and five days later (8th Oct.) my friend’s account blocked and still he doesn’t have any access to his projects! even after creating a ticket and asks for a temporary access to only export his projects! GitLab refused to unblock him! (screenshot in appendix). My friend is not the only one who blocked by GitLab, with a simple search on the web you can find a growing list of blocked accounts. So I decided to move from GtiLab and EVERY Free Software based/hosted/managed on/in USA. When it comes to USA policies, Free Software is a Joke :) GitLab is not the only actor in this discrimination against Persian/Iranian people, we also blocked by GitHub, Docker, NPM, Google Developer, Android, AWS, Go, Kubernetes and etc.

  • ‘youtube-dl’ downloading software removed from GitHub by RIAA takedown notice

    This takedown notice does not necessarily spell the permanent end of youtube-dl. GitHub always immediately takes down any source code project that receives a DMCA notice like this, but the project’s creators will have an opportunity to file a counterclaim in the hopes of restoring youtube-dl’s status on GitHub. We’ll be keeping an eye on the situation as it develops.

  • RIAA DMCAs GitHub into nuking popular YouTube video download tool, says it can be used to slurp music

    YouTube-DL is pretty simple to use: you give the command-line program the URL of any YouTube video, and it will fetch the material and save it to your computer for future playback.

  • Recording Industry Association of America Gets Youtube-dl Kicked Off GitHub

    Microsoft GitHub has removed all traces of the very useful youtube-dl utility for downloading videos from YouTube and other websites, including this one, following a questionable DMCA request from the Recording Industry Association of America.

    youtube-dl is a simple command-line utility that lets you easily download audio adn videos from just about any website with a file file embedded in it. It works on sites like this one. A lot of software, including the popular video player mpv, can use it to download video fragments on the fly so videos embedded in web pages can be opened and played as if they were local files.

    The Recording Industry Association of America submitted a DMCA request to Microsoft GitHub demanding that youtube-dl gets removed from the Internet on October 23rd, 2020. The complaint contains this rather misleading claim: [...]

    Chrome has support for multiple profiles. What differentiates one profile from the other is the Google account that is (or isn’t) connected to a profile. Users can create a new Chrome profile and sync it with their Google account, or they can skip adding an account and keep everything local. What a user cannot do is create a profile that has no name.

Audiocasts/Shows: Noodlings, Python Bytes, Going Linux, Linux in the Ham Shack and Hackaday

  • Noodlings | Inspiration Is Around You – CubicleNate's Techpad

    This is the 21st hot-pocket-sized podcast that won’t scorch roof of your mouth. I have a small collection of vintage or near vintage gaming consoles. I lean mostly in the Nintendo party as I think they have a great grasp on what is fun. I don’t always agree with many of their business practices but the entertainment they have provided is multi-generationally successful. In order to lower the wasted time of hooking these systems up to enjoy and better organize their presentation, I built a Gaming Rack that was inspired by watching a YouTube channel called Retro Recipes. Seeing how nicely laid out and easily enjoyed they were set up, I made the decision that I must adapt this idea to my little world.

  • Hackaday Podcast 090: DIY Linux SBC, HDMI CEC, Fake Bluepills, And SCARA Arms | Hackaday

    Hackaday editors Elliot Williams and Mike Szczys chat about our favourite hacks from the past week. We start off with a bit of news of the Bennu asteroid and the new Raspberry Pi Compute Module. We drive ourselves crazy trying to understand how bobbin holders on sewing machines work, all while drooling over the mechanical brilliance of a bobbin-winding build. SCARA is the belt and pulley champion of robot arms and this week’s example cleverly uses redundant bearings for better precision. And we wrap up the show looking in on longform articles about the peppering of microcontrollers found on the Bluepill and wondering what breakthroughs are left to be found for internal combustion.
