Circuit City will release numerous fun videos every week, and many videos have been welcomed by netizens, so now, now with Xiaobian to uncover the Top10 of the weekly circuit city video leaderboard.
Top10: How to install a new USB3 host firmware on the Raspberry PI 4
Be
In this video, I will show you how to install a new USB3 host firmware on the Raspberry PI 4, which should reduce the temperature of PI 4 1GB 2GB 4GB model 3C - 5C because it saves about 300MW and helps PI4 operation cooling . This will apply to PI 4 1GB PI 4 2GB or Raspberry PI 4 4GB version.

TOP9: turn the BLDC motor of the hard disk into a rotary encoder (with a circuit diagram and source code)
Be
In this video! We will take a closer study of the hard disk's BLDC motor.
We will understand how it works and how we use its structure to determine whether it is clockwise or counterclockwise.
Finally, we connect the motor to Arduino to use it as a rotary encoder.

TOP8: Small to the ultimate, security key SOMU circuit design
Be
Somu is a small FIDO2 security key that you can perform dual-factor authentication on your Google, Twitter, GitHub account, or log in without password on your Microsoft account. Somu is suitable for your USB port, so you will never forget your key.
Somu is a Solo miniature version. We were inspired and made a safe TOMU, so we used its small shape, we added Solo's security microcontrollers and firmware.

TOP7: Using Arduino to make automatic balance robots (attachment code)
Be
In this Arduino Project Tutorial, I used the Arduino microcontroller to make a self-balance root with smartphone control.
This self-balancing robot is a two-wheel robot that implements vertical balance using the closed loop algorithm. The self-balance robot has a variety of modes such as position retention, simple mode, rising mode, and joystick control. This robot can be controlled by smartphone devices or transmitters. Self-balancing robots use accelerometer and gyroscopic data to correct their direction and position.

TOP6: Open source Arduino electronic governor production tutorial (with circuit diagram and source code)
Be
Over the years, I have been trying to do a good ESC.
3 years ago, the first prototype work "very good". It is very large, and BEMF is not so good.
Now, with the final version, I finally got all UP you want. High-speed, good BEMF detection means good torque, PWM control speed and smaller size. Arduino can be programmed using Arduino.

TOP5: Intelligent doorbell (attachment code) based on ESP32 capacitive touch sensor
Be
Video more describes the ESP 32 camera.
This may be the cheapest way for some kind of monitoring camera to install the camera on a small Wi-Fi board. You can use it to do a lot of different things, but what I think is the doorbell, so let me take you to understand how I officially turned this small board to a DIY smart doorbell.
This is a way to turn the M5 Stack ESP32 camera panel into a DIY camera doorbell with a capacitive touch sensor, of course, can also be integrated with ESPHOSTANT.

TOP4: ESP32-based portable non-lossless music player circuit design
Be
MegagRRL is a project for making portable devices that play a VGM file for sound chips used in SEGA MEGA Drive / Genesis and Master System. It uses the high-end chip of famous semiconductor vendors and has focused on the accuracy playback engine, and supports as many VGM file formats as possible, all of which runs Freertos using the ESP-IDF framework.

TOP3: The smart speaker is too expensive, the engineer decided to do itself with the Raspberry, only spent less than $ 30
Be
I am very fascinated by smart speakers. They are like our personal assistant; they can talk to us or control our home appliances.
I want to buy Amazon's Amazon Alexa and Google Home, but they are very expensive, with $ 250.
But my wallet is only 30 dollars. In this video, I showed how I made my own intelligent speaker below $ 30.
I use the Raspberry Pisero W with a $ 10 computer and some SMD components and ICs.

TOP2: Build a smart mirror with a raspberry
Be
In this video, we will show you how to make a simple Raspberry home smart mirror.
It shows the application so that you check the weather and local news when you are ready in the morning.
It is also modular, so if you like, you can easily move it or hang on the wall.
We have created a basic application that can be run on the image, but if you want to write some own code, it can be completely customized.

TOP1: Upgrade! Add AI function for intelligent mirrors based on Raspberry
Be
This video shows you how to add artificial intelligence to a smart mirror based on the hubberber.
We created this Ai and use Wit.ai to make natural language processing. Because the code is open source, no one can help Ai smarter. Unfortunately, artificial intelligence runs some kindness in the Raspberry Party, so now I am now looking forward to further expansion of the Raspberry Pass 4B.
