一节1.5v电池供电鼠标改装锂电池供电

原生
用一节五号电池1.5v，经过鼠标内部dcdc升压到3v，方案一是用ldo将3.7v降压成3v直接接在dcdc后端，可以工作，但过一会儿就不工作了，不知道什么原因，方案二使用一颗led发光管串联降压直接接到供电焊点，3.7-1.8约等于2v经过原生dcdc降压后供鼠标工作，连续测试几天没问题，lex灯会在移动鼠标时闪烁，鼠标耗电量直接可视IMG_20211114_214156.jpg

gerrit 认证总是提示输入密码的问题解决

  1. 首先登陆gerrit 注册（激活）自己的账号。
  2. 生成SSH KEY。 run ssh-keygen -t dsa -b 1024 。 提示Enter file in which to save the key： 输入任意一文件名（例如id_dsa）。 提示Enter file in which to save the key， 连续输入两次回车。 ls /home 或者 /.ssh 。 可以发现俩文件。 id_dsa 和 id_dsa.pub. 前者是密钥，后者是公钥.
  3. 添加public key到gerrit。 打开id_isa.pub, 复制内容。进入 gerrit->settings->SSH Publick key->add key， 粘贴公钥内容。点击add。
  4. 修改 id_dsa id_dsa.pub .ssh 的权限. chmod 700

  5. 尝试 ssh -p 29418 @gerrit......com. 如果看到 下面文字表示成功。
    Welcome to Gerrit Code Review **

    Hi xxx, you have successfully connected over SSH.
    Unfortunately, interactive shells are disabled.
    To clone a hosted Git repository, use:
    可能遇到的问题。

  6. 提示 could not create directory .ssh... 原因可能是你的cygwin 环境没有初始化。 从开始菜单打开cygwin， 会看到会有一些初始化的工作。
  7. 如果遇到Permission denied (publickey). 那可能是你没有添加密钥到ssh-agent. 尝试ssh-add id_dsa. 在add的时候如果遇到Could not open a connection to your authentication agent. 尝试ssh-agent bash. 然后再 ssh-add. add 成功后再run ssh -p 29418 @gerrit......com 应该就可以看到 welcome的提示了。
    3、测试了如上方法都不行依然提示 权限错误或者其他错误，看到协议使用ssh 不妨想到 ssh 终端连接 两个协议应该一样，便 使用xshell 使用证书方式连接 果不其然 可以连接上微信截图_20211112105715.png
    但是 。。。无法克隆 遂 再找到sourcetree 添加ppk 证书 再在 gerrit 服务器提交 微信截图_20211112105825.png
    ok 可以下拉了，但是无法上传 应该是审核问题
