Many large companies choose to keep their hardware closed-source, creating technological barriers and patent copyrights that hinder the development of small-scale innovators. Open source hardware allows entrepreneurs to more easily turn their ideas into reality. From left to right: Arduino Uno, BeagleBone, Raspberry Pi Arduino Uno is very common in the Maker community. Arduino comes … Read more
This year during the New Year, I brought back a DIY small server and set it up at home to create a resource sharing service, allowing family members to store and share some photos and videos taken with their mobile phones. However, since I’m not usually at home, if any issues or failures arise, I … Read more
First, unplug the Raspberry Pi’s power supply to ensure it is powered off while connecting external devices. If you have the operating system installed on a microSD card, you can now insert it into the Raspberry Pi. Next, plug in other external devices such as a mouse, keyboard, and monitor. Finally, connect the power supply … Read more
2024.05.07 1. Overview of Vehicle Detectors Vehicle detectors primarily target motor vehicles and are used to detect data related to vehicle passage or parking, providing sufficient information for smart parking systems to make optimal decisions. Magnetic detection is a new vehicle detection technology that primarily uses magnetic resistance sensors (xMR) to sense the magnetic field … Read more
1. Introduction This article attempts to briefly outline the development history of ARM processors, the evolution of their architecture, including the application directions of different processors. However, we will focus on the Cortex-A series and also introduce the inheritance relationships between different microarchitectures, as well as which design teams they originated from. This will likely … Read more
Click the card above to follow and learn more What is Freeduino? It is an Arduino UNO board without any circuit board. It uses a technology called freeform to interconnect components using wires or copper instead of a circuit board. It looks minimalistic and beautiful! Why did I make this? I often find it hard … Read more
