Objective:Raspberry Pi has a variety of networked ways, either via a wired network or via a wireless network. Through the wired network connection is relatively simple, in the DHCP-enabled router, directly plug in the network cable can be networked, this article introduces the way of the Raspberry Pi wireless networking. Without the network, if there is no screen

Daoteng aircraft, remote control toy car, controlled home appliances, control access, make super computer and so on. The main thing is to be interested. And I was trying to get
What's this?"Roomblock" is a robot platform consists of a Roomba, a Raspberry Pi 2, a laser sensor (RPLIDAR) and a mobile battery.The mounting frame can be made by 3D printers. ROS navigation system enable to make a maps of rooms and use it to reach to the goal autonomously.Who need this?Anyone want to learn the cutting-edge technologies of robotic navigation, mapping, and autonomous driving. This robot can
another host. It can be used with the default settings by just specifying a hostname (e.g. ping raspberrypi.org ) or an IP address (e.g. ping 8.8.8.8 ). It can specify the number of packets to send with the -c flag.Nmapnmapis a network exploration and scanning tool. It can return port and OS information about a host or a range of hosts. Running just would display the options available as well as nmap example usage.HOSTNAMEThe hostname command displays the current hostname of the system. A privi

If you want a bit more advanced-how do you do it directly on the drone and automate the shooting process? In fact, the visual tracking has been in some high-end consumer-class UAV has the application, but

Raspberry Pi backup
We strongly recommend that you regularly back up important files. Backup is usually not limited to user files, but also configuration files, databases, installed software, settings, and even system snapshots.
Here we will guide you through some backup technologies to back up your Raspberry Pi system

You can skip a Playing Song and play the next song.
After installing my system, you can use Raspberry Pi as a server, send broadcasts, play popular songs or listen in English (or something that is permitted by law), and tell friends and family a website, then they can play songs on it. Friends who haven't passed cet6 can add cet6 to simulate the real test environment. Or put it
