5 cara migunani kanggo nggunakake Raspberry Pi. Bagian loro

Hey Habr.

В sisih pisanan 5 cara kanggo nggunakake Raspberry Pi dianggep. Topik kasebut dadi cukup menarik, lan dina iki aku bakal ndeleng sawetara opsi liyane babagan carane sampeyan bisa nggunakake mikrokomputer iki.

Kaya ing bagean sadurunge, aku bakal ndeleng cara sing ora mbutuhake pemrograman.
Kanggo sing kasengsem, tutugan ing ngisor potong.

1. kamera ndjogo

Raspberry Pi bisa digunakake karo meh kabeh kamera keamanan.
Ing ngisor iki bisa digunakake karo Raspberry Pi:

• Webcam USB (contone Logitech C910)
• Kamera IP (Axis, lsp) kanthi injektor PoE (daya 48V diwenehake menyang kamera kasebut liwat kabel jaringan, sing ngidini dipindhah menyang njaba bangunan)
• kamera sing nyambung langsung menyang konektor ing RPi (kaya ing foto ndhuwur).

Ana cukup akeh opsi kanggo ngatur piranti lunak ing kene. Sampeyan bisa nggunakake paket Motion, sing nduweni setelan sing cukup fleksibel. Sampeyan bisa nulis langsung saka console nggunakake ffmpeg, utawa pungkasanipun bisa nulis handler dhewe nggunakake Python lan OpenCV. Sampeyan bisa nyiarake stream video, nggunakake deteksi gerakan, ngirim foto liwat email, lsp.

Sing kasengsem bisa nonton tutorial ing ngisor iki:

• medium.com/@gonzalovazquez/raspberry-pi-and-motioneye-setting-up-your-own-video-surveilance-95444e0faad

penting: Iki wis kasebut ing bagean sadurunge, nanging luwih apik kanggo mbaleni. Kanggo tugas apa wae sing intensif sumber daya (kalebu pangolahan video) ing Raspberry Pi, sumber daya 2.5A merek bermutu tinggi dibutuhake lan heatsink pasif ing CPU dikarepake (sampeyan bisa murah ing China kanthi rega $1- 2 kanthi nggoleki heatsink raspberry pi). Yen ora, piranti bisa beku, kesalahan nyalin file bisa katon, lsp.

2. Rekaman audio

Kanthi mikropon USB, Raspberry Pi bisa digunakake minangka bug lan piranti rekaman audio sing cukup kompak. Maneh, ana akeh pilihan kanggo ngatur piranti lunak - sampeyan bisa nulis file lokal menyang kertu SD, sampeyan bisa siaran menyang PC liyane, utawa siaran liwat jaringan.

• www.heidislab.com/tutorials/audio-streaming-with-raspberry-pi-zero-w-and-adafruits-i2s-mic

Miturut cara, yen sampeyan duwe mikropon, Raspberry Pi bisa digunakake karo Amazon Alexa lan gunakake piranti kanggo printah swara.

3. Prof. foto

Aja bingung p3 lan p1. Ing paragraf pisanan kita ngomong bab kamera ndjogo video, nanging Raspberry Pi uga bisa ngontrol kamera profesional saka Canon, Nikon, Sony, etc. Kamera mung kudu disambungake menyang Raspberry Pi liwat USB.

Perpustakaan gphoto2 и libgphoto2 duwe loro kemampuan kanggo bisa saka baris printah lan antarmuka kanggo Python lan C ++, sing ngijini sampeyan nggunakake Raspberry Pi kanggo kontrol "DSLR", Contone, kanggo photography wektu-kelewatan. Dhaptar kamera sing didhukung Iku cukup gedhe lan nyakup meh kabeh model, saka modern nganti lawas saka 10 taun kepungkur. Libgphoto2 wis cukup API majeng, lan ora mung bisa ngontrol rana, nanging uga ngganti setelan, upload file, etc.

Miturut cara, sampeyan bisa nulis gambar ing kertu memori kamera utawa langsung menyang Raspberry Pi, sing ngidini, contone, kanthi otomatis ngunggah menyang "awan". Ana uga perpustakaan kanggo ngontrol ora mung SLR, nanging uga kamera astronomi (contone ZWO ASI), kalebu malah autoguiding.

4. stasiun cuaca

Raspberry Pi "bisa" ora mung mbukak program Linux, nanging uga wis cukup berkembang peripheral - serial, I2C, SPI, GPIO. Iki ndadekake piranti meh cocog kanggo ngumpulake lan ngirim data saka macem-macem sensor - saka sensor suhu lan asor kanggo dosimeter adhedhasar counter Geiger.

Miturut cara, yen sampeyan kesed tenan, sampeyan bisa njupuk data ora mung saka sensor nanging uga saka web, pilihan iki uga duwe hak kanggo ana. Nanging, papan kanthi sensor kanggo Raspberry Pi ora angel tuku dhewe.

5. Game konsol

Nggunakake proyek RetroPie sampeyan bisa nguripake Raspberry Pi menyang "retro" emulator saka macem-macem nyenengake game, saka Atari kanggo Gameboy utawa ZX Spectrum. Sampeyan uga bisa tuku macem-macem kasus, joystick, lsp.

Aku adoh saka game, supaya aku ora bisa ngomong ing liyane rinci, sapa bisa nyoba dhewe. Sawetara tutorial kanggo sinau:

• thewirecutter.com/reviews/raspberry-pi-game-console

kesimpulan

Muga-muga ana cukup gagasan anyar kanggo nindakake akhir minggu iki. Yen rating artikel kasebut positif, bagean katelu bakal dikirim.

Kaya biasane, seneng eksperimen kabeh.
