用移动电源支持树莓派

一直想要用树莓派做个遥控小车,最先碰到的问题是如何给移动的树莓派供电?网上有很多方案,想找一个简单、便宜、可以长时间供电的解决方案。有文章介绍用移动电源,但是价格都高于100美元并且只提供5v电力输出。我需要一个不但可以给树莓派供电,还可以给L298N至少供7v的电力系统。

L298N是小车上常用的解决方案,网上有很多这方面的介绍,比较适合我这样的新手。它需要至少7v电压来驱动2个马达。我发现小米的移动电源可以支持这个需求。高配版的10000mhA移动电源可以提供12V/1.5A、9V/2A、5V 2A的输出。这个移动电源有一个Micro USB和一个标准USB接口,这样我就可以用一个接口给树莓派供电,另外一个给L298N供电了。10000mhA我觉得怎么滴也能支持整个系统跑一个小时了吧?

这是我打算要做的事情,还需要进一步的验证,希望可行! :-)

Connect-NsxtServer shows "Unable to connect to the remote server"

When you run Connect-NsxtServer in the PowerCLI, it may show "Unable to connect to the remote server".  Because the error message is a little bit confusing with other login issues. It's not easy to troubleshoot. The actual reason is the NSX-T uses a self-signed certificate, and the PowerCLI cannot accept the certificate automatically. The fix is super easy. You need to set the PowerCLI to ignore the invalid certificate with the following command: Set-PowerCLIConfiguration -Scope User -InvalidCertificateAction:Ignore -Confirm:$false

Setup Terraform and Ansible for Windows provisionon CentOS

Provisioning Windows machines with Terraform is easy. Configuring Windows machines with Ansible is also not complex. However, it's a little bit challenging to combine them. The following steps are some ideas about handling a Windows machine from provisioning to post configuration without modifying the winrm configuration on the guest operating system. Install required repos for yum. yum -y install https://repo.ius.io/ius-release-el7.rpm yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm yum -y install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm yum -y install epel-release yum -y install yum-utils yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo Install  Terraform . sudo yum -y install terraform Install  Ansible . sudo yum -y install ansible Install  Kerberos . yum -y install gcc python-devel krb5-devel krb5-libs krb5-workstation

How to List All Users in Terraform Cloud

Terraform has a rich API. However, the API documentation does not mention how to list all users. We can leverage the organization membership API and the PowerShell command  Invoke-RestMethod  to get a user list. 1. Create an organization token in Terraform Cloud. 2. Create the token variable ( $Token ) in PowerShell. $Token = "abcde" 3. Create the API parameters variable in PowerShell. $params = @{ Uri = "https://app.terraform.io/api/v2/organizations/ZHENGWU/organization-memberships?page%5Bsize%5D=100" Authentication = "Bearer" Token = $Token ContentType = "application/vnd.api+json" } Note: You need to replace ZHENGWU with your own organization name. And I used 100 at the end of the URI to retrieve the first 100 users. It can be any number.  4. Retrieve the API return and list the user's email address. $Test = Invoke-RestMethod @params $Test.data.attributes.email
