How to Use image effects on Raspberry Pi
Now you can use the Raspberry Pi camera module ("raspi cam") to add a variety of image effects to your photos, just like using a card camera. The raspistill command line tool provides a wide range of image effects options for Raspberry

Implementing a dialogue robot with Raspberry Pi
Recently, we have implemented a robot that can talk to people with Raspberry Pi, a brief introduction.
Raspberry Pi is the world's most popular micro-computer motherboard, is the le
Requirement
Without a network, a keyboard, or a monitor, controlling Raspberry Pi becomes a problem. I accidentally saw an article today.ArticleThat is, you can directly control the Raspberry Pi through the serial port. Give a decisive try. The effect is good. Share it with others!Pai_^ Preparation
Quick fix for the-is-to-add swap space to the Pi and recompile.Raspbian Swap:raspbian uses a script dphys-swapfile to manage Swap. The standard image includes this turned on by default. The configuration files are located at/etc/dphys-swapfile. The only parameter in the file is conf_swapsize=100 which creates a 100MB swapfile in/var/swap. But, putting the Swapfile In/var was not a good idea was that directory was on your SD card. You can change the f
board, some said to buy the PRC 2706 USB DAV sound card, about 50RMB, investment is not small.
Here are 2 proposals
Scenario 1, if you bought a Raspberry Pi 3 motherboard bought HDMI VGA interface line, then you are lucky, directly to the HDMI interface to the Raspberry Pi
.
Pick the Build you want. I got Windows IoT Core insider Preview Image for Raspberry Pi 2.
You'll need to install the older "File Transfer Manager" If you don't have it. If you had Chrome, you'll need to click the ". DLM" file and open it with the file Transfer Manager. You'll also need to accept the EULAs.
Then you'll get a large ZIP file with the image of you want inside. Unzip somewhere.
Here's
the files.Step 3: Install the flight control module
Time: 5 minutes
Install the flight control part (Raspberry Pi Zero + PXFmini) and connect the jst gh line to the power module and PXFmini on the drone. In this way, the power can be supplied to the flight control part.
Next, you need to install the PWM modulation in the flight control system, connect your ESC line to ESC 1 (also connected to No. 1 Motor
Do you have an idle mobile hard drive or Raspberry Pi? You can use these to create a cheap and low-energy NAS. The final effect is definitely not as good as the NAS for $500, such as those produced by Synology DiskStation. But you can build a low-energy network storage platform-and especially suitable for those who are tired of the National Security Agency's data monitoring, you can store the data in this "
The first blog gave me a long course design, that is, the topic "3G wireless router. The development platform used in this development project is the Raspberry Pi Development Board. The following is the question .....
Objective: To set Raspberry Pi as a 3G wireless router and access the Internet through Huawei's e261.
One, I use the various parts:(1) Raspberry Pi(2) SD card(3) Cable(4) Router(5) a notebookSecond, download http://www.raspberrypi.org/downloads from the official website, I download is Raspbian JessieThird, the Raspbian burned to the SD card, I was in Windows under the operation:Download the Win32diskimager and burn the Raspbian image to SD card;Iv.. Insert the SD
/Raspbian does not release the corresponding deb.If Raspberry Pi uses Arch Linux ARM, there is already a pkg of OpenVPN 2.3;If you select Raspbian (Debian), you may need to compile OpenVPN from the source. You have not tried it yourself.
The following example uses Raspbian (my environment does not have IPv6 at the moment). I believe that Arch users must be under no pressure.Arch problems: If hostapd is up,
configuration means the following:// indicates the use of localhost // If there is a network card ech0, then use DHCP to obtain the IP address (this network card is the local network card, not the WiFi network card) // indicates that if there is a WLAN device, use the WLAN0 device name // indicates that the WLAN device can be hot-swappable // If you have a WLAN NIC Wlan0 (which is the WiFi network card), use DHCP to obtain the IP address wpa-ssid "Your WiFi name"// indicates the connection SSID

This project uses Raspberry Pi with ultra-low-cost software radio (SDR) hardware to receive tracking information sent from an airborne S-mode transponder outside millions of miles. The Raspberry Pi is equipped with a smart 3.5-inch TFT display to provide a convenient overview of aircraft activities.

The first time to make Raspberry Pi, because the Raspberry Pi can not directly connect the monitor, so use remote connection, here, I use a network cable to connect the way, notebook and
Raspberry Pi--a card-type machine that is based on the size of a Linux system and has only a credit card size. Raspberry According to the inventor's idea, he was designed to reduce the cost of learning program development. You can understand it as a rudimentary version of the computer. Raspberry
Mac corresponding to the IP on the line (specifically because each router model is different on Baidu bar)If the Mac doesn't know, look in the router's client list.Mac is usually the beginning of b8-.If you don't unplug your cable this time, you should be able to find 2 IP and two Macs.You can switch off the Raspberry Pi to unplug the network
