Raspberry Pi Unveils AI Camera Kit at Embedded World 2024
Raspberry Pi unveiled its latest at Embedded World 2024: the AI Camera kit. It pairs a Raspberry Pi Zero 2 W with a 12MP Sony IMX500 sensor, offering a 76-degree field of view for AI computer vision projects. The sensor has onboard processing for neural network models, easing the load on the CPU. It can track people in real-time at 30 fps, showcasing its performance. With 200mm flat flex cables, it's compatible with all Raspberry Pi models, making AI integration accessible for developers.

ONE: Open-Source Self-Balancing Unicycle Robot
ONE is a self-balancing unicycle robot project using IMU technology and STM32 microcontrollers. It's powered by two PWM channels for motor control, two timers for encoder data, and several ADC channels for gyro and accelerometer data. The repository includes STM32 firmware and detailed 3D models. Though lacking circuit board schematics, the circuitry is straightforward for skilled engineers.

Engine check notification does not provide any value!
In the midst of my journey to another city with my kids, a sudden and cryptic “Engine check” notification flashed on the car’s dashboard. To my dismay, no further information or details were provided, leaving me clueless about the severity of the issue.
Faced with a situation, I had three choices:
- Ignore that notification and proceed,...
SiC Technology for Data Center Cooling Applications
While the number of transistors in a chip increases exponentially as our demand for increases so in that trend, power elecronics can't be left out. The Silicon Carbide(SiC) based solutions for power conversion promise higher power handling capacity along with efficiency and lesser need to do active cooling of the power device.

Standoff Results in Robot Dog Disabled by Suspect
In Massachusetts, during a standoff, a suspect disabled a police robot dog. Despite being shot, the robot, SPOT, facilitated the suspect's surrender. This highlights the role of robots in tactical scenarios, reducing human risk. The damaged robot, Roscoe, was sent back to Boston Dynamics for assessment, with a replacement planned for the state police.
