In the era of the Great Visitor, the rise of open source hardware, let everyone try to design some projects themselves, although there is still a little higher, if you are enough, enough fever, really should buy a few Raspberry Pi (Raspberry Party) Or Arduino is going to play. Maybe you still don't know what the Raspberry Party is, and what the Raspberry Pist can be used. Let us come slowly, one step by step and find its fun.
What is open source hardware?
Open source hardware refers to a computer and electronic hardware design with free and open source software. Open source hardware begins to consider opening sources other than software, and is part of open source culture.
This word is mainly used to reflect the hardware design of free release details, such as circuit diagrams, materials list, and board layout data, usually using open source software to drive hardware.
Raspberry Party is one of open source hardware, which is equipped with ARM architectural processor, 256MB memory (B type has been upgraded to 512MB). The Raspberry Pi only has a credit card size, which is probably a match size, which can perform games like Raythene III Arena and playing 1080P movies. The purpose of the Raspberry Part is to stimulate the basic computer science education in the school at low price hardware and free software. It is intention to design to learn computers to children, not give you these Geek to toss.
Like Watercolorbot, there is still relatively small, but in the spirit of "Tian Xingjian, Emirator is tossed", we can still do a lot of interesting things with Raspberry. Many Extreme passengers have realized a lot of fun, after you see it, do you have a desire to try? Let us look at what is interesting to do with the Raspberry Pist.
Raspberry Transformation Weibo Robot
The biggest point in the Raspberry Pie is a strong scalability, and the user can add various sensors on this basis. For example, using a temperature sensor to achieve monitoring temperatures, the simple detection temperature is boring. Let us transform, turn the temperature monitoring result to the microblog, the Raspberry Pass Transformed Weibo robot, send a Weibo every time a period of time. Maybe you may not write code, don't know how to configure Weibo interface. It doesn't matter, some people have already done some work, as long as you can do it, you will google, you can also realize it.
In addition to the temperature sensor, you can try other sensors to achieve new gameplay, waiting for your attempt.
Raspberry Party Makes Real Douban FM
The Douban FM is really made into an FM launch station, listening to the radio. Although it seems to be more, it is very cool when it is tossing, and it feels cool. When I heard this concept, I didn't start with it. In fact, I think is more simple, and the Raspberry Pivot can be networked. It can be loaded into the operating system extension function, which is more convenient for us to toss. It is only necessary to download the MP3 music code stream from the Douban FM with the Raspberry FM, and the audio signal is modulated into a frequency modulation signal. You can use a radio or a mobile phone. The specific code achieves good use of Github, can also be found.
If you have a more fever, you can try this method, add your Raspberry version of the Douban FM plus a display.
See video
Just add a display module, an infrared remote control, an infrared sensor, and of course, the difficulty is difficult to improve, and a certain programming basis is required.
Raspberry Pie Realizes Remote Opener
When you arrive in the company, send a directive with your mobile phone, the door is automatically opened. Maybe it will be more science fiction before, very passenger, and the difficulty of production will be high. It is not very difficult to use the Raspberry Psef, you need to study the door lock, brush the operating system, configure the network, connect the hardware, and write a small Web Server with the code. Then enter the correct password, you can unlock it. If you are higher, you can write an Android and iOS program, check in with your mobile phone, so every time I forget the door card, use the mobile phone to remotely open the door.
Kindle + Raspberry Pi = PC
How can PCs can be assembled? As long as you have a Kindle and Raspberry Pie, it can be transformed into a small PC. This is difficult for this difficulty, but the more challenges, the greater the fun. A jailbreak's Kindle plus an external keyboard, the Raspberry Pie as a processing center, Kindle as a display, it looks like a small PC, although only ancient command line mode, in Kindle's HACK, at least Improve a lot of hardships.
Homemade Raspberry Piece
Using Raspberry PC-controlled rotor aircraft, you can equip the micro-camera for smartphones, a combination of aerial photographing relative to ordinary rotor aircraft + cameras, not only cost, but also achieve more complex features, such as aerial photography or real-time aerial photography Image wireless transmission, aircraft controlled by mobile phone compared to simple buying mobile phones, this own modified Raspberry Fair can also expand the function, is it cool.
