目前三种可调焦距镜片

利用两个眼球的注意点来测量物体的距离

顶部有距离感应器,侧片有眼球追踪器,二者综合测量目标距离,再利用自动对焦镜片调焦。

原型很笨重

软路由搭建攻略:从小白到大白

写在最前

本文写于2018123日,其中的硬件软件资讯随时可能更新换代,请阅读本文的同时结合搜索引擎更新相关资讯。

最近突然很流行【软路由】这个关键字,然而在搜索引擎搜索出来的文章大多都相当硬核,让许多想尝试的小白望而止步,所以我就通过自身的经验简单的普及一下软路由的基础知识,以及软路由的搭建教程,因为这方面的文献比较少,多数都是本人自己胡说八道,如果文章中有什么错漏欢迎大家指出来,我会及时修正。

这篇文章接下来会说什么:

  • 软路由的定义
  • 软路由的优缺点
  • 什么人会使用软路由
  • 软路由的挑选
  • 软路由的组建
  • 软路由的设置
  • 硬路由桥接软路由发射WiFi

    这篇文章不会涉及的知识点:

  • 软路由虚拟机多系统(对于新手来说太麻烦而且我个人觉得暂时没有必要)
  • 黑群晖之类的NAS搭建(三大妈已经有其他作者写过啦)

    总的来说就是作者会尽可能的从新手的角度出发,尽量让各位小白都能看懂然后早日打造出自己的软路由


    什么是软路由

    在了解什么是软路由之前,我们先定义一下【硬路由】这个关键词,硬路由就是我们现在随便在京东淘宝搜索【路由器】搜出来的,从一开始就是按照路由器规范设计出来的硬件设备。而相对的【软路由】则是指,利用现有的硬件(可能是电脑或者树莓派之类的)配合软件来实现路由器的功能。

    软路由能做什么

    软路由对比硬路由优势在哪里?

因为关键词审查的问题,这里只放截图:

安装完毕后提示信息类似于:

Requirement already satisfied: shadowsocks in /usr/local/lib/python2.7/dist-packages (2.8.2)

创建的时候注意,配置文件其实可以任意起名,只需要在第4步,第5步时修改为对应的文件名就好。

提示:树莓派使用nano编辑器来创建文件,比如创建名称为 sslocal.json 的文件,则输入: sudo nano /etc/sslocal.json

nano编辑器的使用方法见这个教程:https://www.cnblogs.com/vamei/p/6228499.html


另外,自启动还有个方法:

后台长期启动ss

开机自动启动:

在  exit  之前加上一行:

按  Ctrl+O  并回车保存,按  Ctrl+X  退出编辑器。
