The author designed this robotic actuator to be a powerful, easy-to-build, and relatively inexpensive solution to creating dynamic robots. Robots like Spot, Atlas, and the MIT mini cheetah easily impress the eye with their agility, speed, and overall ability to mimic natural motion. With OpenQDD, creating high-performing actuators at an affordable price is possible.
Specifications of the project:
The actuator uses a 90KV Eagle Power BLDC Motor as well as an ODrive S1 FOC controller. In closed-loop control mode, the S1 allows you to control the position, velocity, and torque of a brushless motor.

📰 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.
