Brake Air
In this day in 1872, George Westinghouse patents the air brake.
In the air brake’s simplest form, referred to as a straight air system, compressed air is directed to a brake cylinder, causing its piston to apply force to mechanical linkage, which linkage is conventionally referred to as the brake rigging. The brake rigging, in turn, is connected to brake shoes that are pressed against the car’s wheel treads (some types of passenger cars instead use disc brakes). The resulting friction slows the car by dissipating its kinetic energy as heat.
The brake rigging is often quite elaborate, as it is designed to evenly distribute the brake cylinder’s force to multiple wheels.
Tapo Switch
TP-Link is a Chinese technology company that manufactures network equipment and smart home products. The company was established in 1996 in Shenzhen. It has subsidiaries operating globally and owns several brands, including Deco, Tapo, Omada, Omada Pro, VIGI, Aginet, Kasa Smart, and Mercusys.
The company has been investigated by the governments of India and the United States, citing national security risks.
In a first start into home automation, I got this plug. It allows me to schedule my electric blanket to always come on at a prescribed times
The setting up was simple, and within 20 minutes I had it turning on and off with the phone.

HarmonyOS
HarmonyOS is a computer operating system developed by Huawei for smartphones, tablets, smart TVs, smart watches, personal computers and other smart devices.
It has a microkernel design with a single framework: the operating system selects suitable kernels from the abstraction layer in the case of devices that use diverse resources. The latest version is HarmonyOS 6, released on 22 October 2025.
Strandberg
Founded by Ola Strandberg in 2007. These guitars are known for their ergonomic characteristics.
The headless design makes a more balanced instrument. The two scoops on the downside make it easy to rest the guitar on the upper leg, either in a horizontal alignment or at an angle.
And at only 42mm deep, the instrument can be kept close to the body, as explained by Tim Pierce.
But my issue is that this could have been a good opportunity to make a symmetrical guitar that could be strung for left or right-handed players.
Axial Flux
An axial flux motor is a geometry of electric motor construction where the magnetic flux is aligned parallel with the axis of rotation, rather than radially as with the concentric cylindrical geometry of the radial flux motor.
Advanatges:
Compact and Lightweight Design:
Axial flux motors have a disc-like structure that reduces their axial length, often making them about 50% smaller and lighter than traditional radial flux motors. This compactness allows for greater installation flexibility, especially in space-constrained applications.
High Torque and Power Density:
These motors can deliver up to four times the torque density compared to similar-sized radial motors. The effective magnetic surface area on the rotor’s surface enhances torque production, making axial flux motors particularly suitable for high-performance applications like electric vehicles.
Improved Efficiency:
Axial flux motors achieve efficiency levels exceeding 96%, thanks to their shorter magnetic flux path. This design leads to reduced energy losses and allows for sustained peak power output, which is crucial for applications requiring high efficiency.
Effective Cooling:
The flat structure of axial flux motors facilitates better cooling compared to traditional designs. This is particularly beneficial in high-load operations, where effective heat dissipation is essential for maintaining performance and longevity.
Flexibility in Design:
The design of axial flux motors is adaptable, allowing for customization to meet specific application requirements. This flexibility makes them suitable for a wide range of uses, from electric vehicles to robotics and industrial machinery.
Low Noise and Vibration:
Due to the even distribution of the magnetic field, axial flux motors operate more quietly and smoothly, making them ideal for noise-sensitive applications.
Disadvantages
Manufacturing Complexity:
The disk-shaped design of axial flux motors requires high-precision manufacturing processes. Proper alignment and intricate assembly are crucial, making the production more complex compared to traditional radial flux motors.
Thermal Management Challenges:
Axial flux motors often face difficulties in dissipating heat due to their compact structure. The sandwich design can complicate thermal management, necessitating advanced cooling methods such as immersion oil cooling or liquid nitrogen cooling to prevent overheating.
Higher Costs:
The use of rare-earth magnets and high-performance materials increases the overall cost of axial flux motors. Additionally, the specialized manufacturing processes required can further drive up expenses, making them less economically viable for some applications.
Mechanical Stress:
The wide rotors in axial flux motors may be prone to mechanical deformation under excessive loads. This can lead to reliability issues and necessitate careful design considerations to ensure structural integrity.
Precision Requirements:
Maintaining a uniform air gap between the rotor and stator is critical for performance. This requirement adds to the manufacturing challenges, as any deviation can significantly impact the motor’s efficiency and effectiveness.
Immature Manufacturing Equipment:
The industry lacks sufficient knowledge and equipment for the mass production of axial flux motors, which can hinder widespread adoption and scalability.
