📰 The Flipper Zero gets an App Store
An updated mobile app now makes it possible to find and install free apps on the stock Flipper Zero firmware.
The Flipper Zero — a dolphin-themed digital multitool — now has a mobile app store, which makes it much easier to browse and install third-party tools and plug-ins right from your phone. Now, the marketplace is built into the latest version of Flipper’s official app. All the available apps are reviewed by the Flipper team.
At launch, the Flipper app store isn't exposed on the web; instead, apps are made available on the Flipper Zero's companion mobile app. Thus far, there's no way for a developer to monetize their contributions: everything in the app is downloadable free of charge, and automatically sent to the linked Flipper via Bluetooth.

📃 Mechanical Pencil Solder Feeder Hack
The soldering hack involves creating an ultra cheap solder feeder using a mechanical pencil and solder of matching diameter. The idea is to use a mechanical pencil with the feeder button located on the side, which allows for easier extension of the solder wire.
The process includes opening the lead compartment of the pencil, removing the cap, eraser, and lead rods, and then inserting the straightened solder wire in place of the lead rods. By holding down the "extend lead" button, the solder wire is threaded through the pencil's tip, creating a simple and effective solder feeder.
This DIY solution not only helps manage solder wire but also provides greater stability during soldering, particularly when working with small components like SMD chips. The project is cost-effective and easy to execute, making it a valuable addition to any soldering toolkit.

⚡️ "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.
