How to create a task tracking plan, this problem has been troubling me, recently because of life encountered things, many previously established learning task plans are now postponed, so they are looking for a solution, how to arrange their own plans, whether it is a project or learning to have a deadline, not because of other things, and the original defined deadline delayed to an unpredictable State, do a matter, draft a plan, read a book, we all need to establish a good plan in advance, make…

Recently I needed to make my own mounting parts because I needed to install an Intel Realsense D435i for Vision SLAM on my Robomaster EP, so I decided to get my hands dirty and use 3D printing to do it. Although I have an overlord pro on hand that I purchased five years ago, due to the age of the machine, I need to manually optimize and tweak the performance of this printer, and considering the cost of time, I decided to purchase a new 3D printer for the printing of accessories, this overlord…

The earliest project to run MPICH on a Raspberry Pi cluster would be Raspberry Pi at Southampton, in which professor Simon Cox and his son together to build an MPI cluster consisting of 64 Raspberry Constructs and Legos. This project is already 10 years old, and at that time the raspberry pi 1 B+ was used, and due to the limitations of the performance of the 1st generation, the whole cluster could only be used for MPI learning, which is still under-utilized in high-performance computing.…

The system of raspberry pi zero w is currently raspberry pi official os image is armv6hf debian 11, and ROS2 official support only ubuntu debian aarch64, not support arm32, so to use ROS2 on raspberry pi zero w must be built from source. So the problem is that if you compile directly on zero w, obviously because of the hardware (cpu: 1 core, memory: 512M), the compilation will be extremely slow, I also tried to use armhf cross-compiler toolchain to compile the ROS source code on aarch64 system,…

At the beginning of the year I planned to spend six months researching autonomous driving, and computer graphics, so I started researching hardware for developing autonomous driving systems. The first thing I considered was the jetbot that was open when nvidia released the jetson nano platform in 2019, which is basically a toy car equipped with a 3D printed body, two small wheels, and a jetson nano developer kit, a camera, and official project address, considering the cost needed to build the…

I was introduced to a small foreign company by a friend in July last year, and I decided to leave my job after six months to start my freelance career. I hope to devote more time to the fields I am interested in, such as art, film, music, and computer, and to enrich my knowledge by exploring new fields. When I was in college, I liked to tinker with computers, and after I graduated, I worked in the IT company. When I first started to work, my knowledge was very narrow and I stayed in my area of…
