# Sixth Lichuang Electric Competition# Maker launch vehicle

* 1. Introduction to project functions

Why make a rocket light? During the opening of the training camp, my country's aerospace project made new progress. The Shenzhou-12 spacecraft successfully sent three astronauts to the space station independently designed and built by my country. I just wanted to buy a desktop atmosphere lamp. TB seems to be similar in appearance. The shape is relatively simple and has no freshness, so I got the creative inspiration of the rocket lamp and took advantage of the offline voice training camp.

This is not just a simple ambient light, but also a project that carries the dream of a hardware engineer. The offline voice control solution is realized through Chiplintelli's CL1122 module + main control MCU (STC15W). You can use voice to control a series of controls such as the ignition and launch of the "Maker". See the project demonstration video for details.

*2. Project attributes

This project is the first to be made public to the public, and the appearance of the project is modified based on the design of the Shenzhou 12 manned spacecraft.

* 3. Open source agreement

 GPL 3.0 Agreement

*4. Hardware part

The hardware part is composed of offline voice module + MCU main control + humidifier drive circuit + WS2812 aperture. Details are as follows:

Offline voice module: Qiyingtailun CL1122 module

MCU main control: STC15W4K56S4 (don’t ask me why I chose this chip at this time, go to the inventory design)

Humidifier drive circuit: Humidifier USB spray module

WS2812 aperture: The motherboard comes with WS2812+WS2812 light strip

The hardware part is relatively simple and often used. It is mainly divided into offline voice module, main control MCU module, WS2812 module, relay module and peripheral interface module. I will not describe it too much here.

*5. Software part

The core of the program is Resolve_Messages_Sent_By_The_Server. We can use this code to determine whether it is controlled, then determine which control instruction it is, and finally let the microcontroller perform the corresponding action. Reference code below

*6. BOM list

 3D printing: Print it yourself or create a 3D monkey

Panel printing: Jialichuang panel printing

For a detailed list of other components, please see the automatically generated BOM table below.

*7. Contest LOGO verification
