⚡️ "Superconductor Drama" with the LK-99 and the first successful replication
For the past week, the social media has been aflutter over a claim for a new superconductor that works not only well above room temperatures, but also at ambient pressure. In a race to getting a Nobel prize, the two scientific articles have been posted, which you can find here and here.
At first, the discovery has not been posted here due to the skepticism in the scientific community, which is pretty much explained in the first video supplied to this post. However, today, more than an hour ago, the first claim of successful replication of LK-99 came from the Huazhong University of Science and Technology. The superconductor they received is shown on the second video.
If more replications to follow, this would mean a new technical revolution in everything that involves electronics and beyond. This technology could allow previously impossible things such as widespread of electricity transmission without loses.

⚡️ DIY Scientists and Institutions Are Racing to Replicate the Room-Temperature Superconductor
All across the world, top labs and citizen scientists alike are racing to replicate the results of a viral study that claimed to have invented a long-sought technology that could revolutionize our daily lives: a room-temperature superconductor.
Sinéad Griffin, a staff scientist at Lawrence Berkeley National Laboratory, presented theoretical evidence that LK-99 has possible pathways for superconductivity in a tantalizing preprint published on Monday. A rush of experimental results is also likely forthcoming, which could help to confirm or deny that LK-99 is a room-temperature superconductor.
For a period on Tuesday, the betting markets implied that the most likely (with 60% chance) result was that the papers would be replicated.

📟 Felini - The Swiss Army Knife of Electronic Debugging Tools
This is a compact device for experts and electronics enthusiasts alike. It is designed with the aim of integrating as many common tools (like a logic analyzer, a JLink programmer, adapters, etc.) as possible into one handheld device. Besides its primary features, Felini offers additional capabilities like a USB CAN bus adapter, USB to UART, SPI, I2C, and RS485 conversions, a system for quick-checking I2C devices, and servo control through PWM. It can also measure and count pulses and signal frequencies.
The source code for Felini, based on ESP32S3, can be easily adapted to create a simplified version without a screen, using readily available and affordable ESP32S3 kits, providing even the most financially challenged students with a sufficient toolset. Furthermore, Felini's PCB, SMT, and 3D printing models are available on Github, making it easy for anyone to create their own Felini.

📰 NY Times: LK-99 Is the Superconductor of the Summer
The new article by New York Times summarizes findings regarding the LK-99.
The story began when a team of South Korean scientists from the Quantum Energy Research Center claimed to have synthesized LK-99 and provided evidence of its superconducting properties, including a video showing levitation over a magnet. However, experts in the field of superconductivity and solid state physics remain skeptical, as the data provided by the Korean scientists is not entirely convincing.
The resistance of LK-99, at the temperature claimed to exhibit superconductivity, is still much higher than what is expected from a true superconductor. Furthermore, the levitation demonstration is not definitive, as non-superconducting materials can also partially levitate in a similar manner.
For more up-to-date information: LK-99's Wikipedia page updates several times a day with the new information from the scientific articles and their outcomes.

🤖 The PolarBear - Open-Source 3D-Printable Multipurpose CNC Machine
Computer numerical control (CNC) is a method for automating control of machine tools through the use of software embedded in a microcomputer attached to the tool.
Nice project of a useful desktop machine that can be used in many ways, from soldering to 3D-printing, depending on the task, tool, and a program.
Thanks to the PolarBear's unique design and kinematics, the limits between the needs of the different functions are more blurred. While it can be as fast as a 3D printer, it can be rigid for use as a CNC milling machine as well. The machine can be build of available off-the-shelf components and has 3D-printable parts.

Archax is a 4-meter-class robot that can be operated by a human pilot. It has two modes: "Robot Mode," where all movable parts are operational, and "Vehicle Mode," where it folds its arms and extends its front legs 60 degrees forward, assuming a lower posture. In each mode, both the operable parts and the movement speed change.
The robot stands between 3.9 meters (in Vehicle Mode) and 4.5 meters (in Robot Mode) tall, with a total weight of 3.5 tons. Its design incorporates a blend of materials, including steel, aluminum alloy, and fiberglass-reinforced plastic.
The cockpit is equipped with four monitors and nine cameras, providing operators with comprehensive visibility and control over the robot's numerous joints and movements. While initially an entertainment-focused prototype, Tsubame Industries envisions expanding Archax's applications beyond entertainment, aiming to develop more versatile and practical robotic systems in the future.
