Appreciation of single chip microcomputer DIY works, beginners come in to worship

Single chip microcomputer diy Appreciation of works , Beginners come in to worship

As Arduino Community moderator , It's my bounden duty to show my skills ！

The following projects are completed by individuals independently , Because there are too many works , The following will be divided into hardware and software and hardware combination

Hardware

It mainly includes robots 、 Smart hardware 、 Board class 、 And indescribable mystery works ... The following is arranged according to the implementation difficulty from low to high ：

/// Insert a ： At the beginning of this year, I recorded a set of systematic introductory single chip microcomputer tutorial , If you want, just ask me for it. It's free , I can send a private message ~ Click on my avatar in black font and I can also get it . I've been relatively idle recently , Take me to finish the design , Take students to provincial or above competitions ///

3. The smallest self balancing robot in the old hemisphere Nano（ It's hard to make ***）

Super mini, super cute self balancing robot , It is also the second generation of egg yolk series , Autonomous balance and motion are realized by gyroscope and accelerometer , Covered in sensors , Cute and powerful .

The platforms and technologies involved mainly include ：Arduino、3D Print 、IMU Data fusion 、PID control

Less than height 10cm Self balancing robot Nano Although the robot is small , Five zang organs

Details of the project , Demo videos and production tutorials are here ：

6. Coin size “ Raspberry pie ” Veneer  -- MiniPi & MiniPi Plus（ It's hard to make *****）

And low end Arduino equally , Raspberry pie is a star product in the open source world , But because individuals are not satisfied with their “ Huge ” Body shape , So he devoted himself to research and development “ Raspberry pie compression technology ”, So get super mini powerful MiniPi.6 layer PCB Design , The size is similar to that of a coin , On the performance Cortex-A53 Quad core processor , Bring their own WiFi, function Android perhaps Linux System , Ask who else has a smaller card computer ？？ Anyone who has used raspberry pie knows its power .

The most difficult part of this project is , stay MiniPi The first edition of , I use four layers PCB Conduct layout Come out ... Halfway through, I found that it was almost a dead end , So I was going to spend money to find a professional team to help me layout, The answer is DDR3 I'm sure you can't do four layers of boards , then ...... God knows how I got through it , And the board works normally when it comes out ！（ Of course, such extreme operation will bring some hidden dangers of stability , So the following versions are added to 6 layer , The cost of proofing has doubled ）. In addition, the following uboot transplant 、 Kernel tailoring and porting 、root-fs Customization is also troublesome , There are many pits .

Technology involved ： Precision multilayer PCB Design 、Uboot transplant 、Linux kernel transplant 、 Lanxiang welder skill

The production process of the project is here , This project is not open source for the time being due to the great difficulty of production ：

Combination of software and hardware

The following works are relatively complex systematic projects , A combination of technologies in multiple fields , Therefore, the difficulty will be relatively higher .

1. Desktop intelligent housekeeper robot  -- Little krypton （ It's hard to make ****）

2. Science fiction reality system  O-World（ It's hard to make ****）

This is a fusion CV/AI、3D、IoT、 Smart home 、 And the software and hardware systems of many technologies such as robots , It shows the short-term future I understand , For the above dazzling technical terms, the most likely way to be applied , The whole project planning 、 Design 、 Developed for a long time , See the video demonstration for the effect .

O-World Science fiction reality system

3. Table tennis robot based on high-speed binocular camera system （ It's hard to make *****）

I like playing table tennis very much , This robot is a project I tried to challenge when I was in school , All the technologies involved are from the circuit 、 Some mechanical structures 、 industrial design 、 Software programming 、 Algorithm implementation and so on are basically completed by one person , I've been tossing around for nearly a year . The whole system can be said to use all the knowledge I can and can't , It's also one of the projects I've been working on for the longest time .

rendering A physical picture

These are some interesting projects I have done for the time being .

Of course , These are just a small part of what I have done in my tossing career in recent years , I have loved electronics since I was a child （ Bring your own demolition property ）, Also love tossing , There are often some strange brain holes thinking about whether they can realize it with their own hands , For me, making robots is the pleasure of God making people , And although I call myself a geek , Also accumulated a lot of knowledge in the continuous toss , But the more you touch , I feel that what I have to learn is far from enough .

in addition , Personal learning path and technical direction are actually very confused （ The main reason is that there are too many points of interest ）, From hardware to software development, and then to pure algorithm , At present, the main research direction is deep learning in CV Applications in the field , So actually in the direction of software , I also have many interesting projects to share , However, the problem limited by the subject is open source hardware , Other projects will be saved and will come slowly later ~
