DIY Smart Multipurpose Battery Tester
Green Energy Oct 14,2024
In recent years, the market has been flooded with low-cost batteries, many of which originate from unregulated manufacturers. A significant concern with these batteries, is the inaccurate labeling of capacity. Often, these batteries claim to have high capacities sometimes exceeding 10,000mAh at prices that seem too good to be true. In reality, many of these batteries fall far short of their advertised capacity, providing poor performance and posing potential safety risks due to overcharging or o...

Arduino 3D Printed self Balancing Cube
Pavleski Oct 10,2024
 Self-balancing devices are electronic devices that use sensors and motors to keep themselves balanced while in use. They uses gyroscopic sensors and accelerometers to detect the movement of the balanced object and adjust the speed and direction of the wheels accordingly, allowing to control the device through shifts in their weight. This time I will present you a project in which the balanced object is a 3D printed plastic cube, inside which the reaction wheels and control electronics...
