Ngiyacabangaabaningi bethu baphupha njengezingane zokuthola ngolunye usuku ilungelo lokukwazi ukuba nalo noma ukundiza irokhethi elizenzele lona noma umkhumbi omncane owenzelwe ukundiza futhi ngaphezu kwakho konke ukuba nomyalo ongasinika inkululeko yokuwuqondisa ngokuthanda.
Namuhla, kanjalo, lelo phupho selifezekile ngabaningi Yebo, kunezinhlobo ezithile zezentengiselwano ongazithenga noma uma kwenzeka ama-drones, nakho okufana nalokho ebesingakufisa njengezingane.
Kodwa masithembeke, iningi lethu belingathanda ukuklama le divayisi ngezandla zethu nangaphezu kwawo wonke amandla okufunda ukuthi ungayihlanganisa kanjani nokuthi ingxenye ngayinye isebenza kanjani.
Futhi kuhle namhlanje ngiza ukuzocobelela ulwazi Ngithole enetheni ngokuthile okufana nalokho engikuchazayo futhi lokho iphrojekthi yeCygnus-X1 ithuthukisa ibhodi lomthombo ovulekile yokulawulwa kwe-jet engine kanye nezinhlelo ezihlobene ebhodini.
Abathandekayo bangasebenzisa ipuleti ukuzinzisa ukundiza kwamarokhethi enziwe ekhaya futhi ngaphezu kwakho konke futhi into ebaluleke kakhulu ngale phrojekthi ukuthi ukuthuthukiswa kwephrojekthi kusatshalaliswa ngaphansi kwelayisense le-GPLv3.
Esingathola ngayo inani elikhulu lemidwebo etholakalayo, ukwakheka kwe-PCB kanye nemininingwane ye-EasyEDA (Electronic Design Automation) simulator.
Esinye isici esivelele kuphrojekthi ukuthi ibhodi lihambisana ngokuphelele nezindawo zokuthuthukiswa kwe-Arduino IDE ne-Platformio.
Ngaphezu kokuthi izingxenye zesoftware zibhalwe ku-C ++ futhi njengesisekelo, i-SAMD51 microcontroller iyasetshenziswa, Isebenza kumvamisa we-120 MHz futhi ine-1 MB yememori ye-Flash eyakhelwe ngaphakathi.
I-Flash yangaphandle noma ikhadi le-SD lingasetshenziselwa ukuqopha i-telemetry ngenkathi indiza. Imininingwane nemiyalo kudluliselwa ngeBluetooth Low Energy (BLE), ekuvumela ukuthi usebenzise i-smartphone ejwayelekile ukulawula.
Kunikezwa iziteshi ezintathu zokulawulwa kwe-servo: ezimbili ukunyakaza kombhobho lapho i-vector yokufaka ishintsha futhi enye yezinye izinhlelo, ngokwesibonelo, ukwenza kusebenze ukuthunyelwa kweparachute. Kukhona futhi ama-pyrochannel amabili we-ignition kanye nama-plug akhanyayo nesiteshi esilawula izimoto ezisebenza ngogesi ukushintsha ikhoyili nge-gyro.
2S noma 3S LiPo amabhethri angasetshenziswa njengomthombo wamandla. Phakathi kwezinzwa ezisetshenzisiwe kukhona i-accelerometer-gyro ehlangene (IMU BOSCH BMI088) ne-altimeter (MS560702). Izixhumi ze-UART ne-I2C ziyatholakala ukuxhuma izinzwa ezengeziwe njengemodyuli ye-GPS.
Ezimpawu ezivelele kuphrojekthi, kukhulunywa ngokulandelayo:
- Ngokuya nge-SAMD51 microcontroller egijima ku-120 MHz ene-1 MB ye-flash. (ATSAMD51J20A-MUT).
- Ilawulwa yi-Bluetooth Low Energy (BLE), lokhu kuvumela idatha ukuthi ithunyelwe futhi yamukelwe phakathi kwerokhethi ne-smartphone.
- Iziteshi ze-Servo ezi-3 (Iziteshi ezimbili zisetshenziselwa ukufaka i-vectoring kanye nesinye sezinto ezinjenge-mechanical parachute ejection system).
- Iziteshi ezi-2 zePyro ezikwazi ukushisa izibani zezimoto nocingo lwe-nichrome. Ilawulwa ngokuphelele yi-PWM ngokulawulwa kwamanje okuguqukayo.
- Isilawuli semoto se-1 DC ngalezo zikhathi lapho udinga khona ukulawula amandla ngevili lokuphendula.
- Isebenza ngamabhethri e-LIPO 2S ne-3S. I-3S ikhetha (11,1V)
- Kubandakanya i-terminal arming ukugwema ukwehluleka eziteshini ze-pyrotechnic.
- I-six-axis IMU (BOSCH BMI088) ne-altimeter (MS560702)
- Imbobo yekhadi le-SD ukuze ugcine idatha yakho.
- 16MB wesitoreji se-flash sangaphandle. Gcina idatha ngesikhathi sendiza (ukuxhumeka kwekhadi le-SD kungahle kwenzeke ngezikhathi zendiza ngenxa yokudlidliza)
- Ama-LED we-Buzzer ne-RGB Neopixel
- Ukuxhumeka okungeziwe kwe-UART ne-I2C uma kwenzeka ufuna ukuxhuma izinzwa zangaphandle njengemodyuli ye-GPS.
Ekugcineni, uma unesifiso sokwazi okwengeziwe ngakho wephrojekthi ungabheka imininingwane, amabhukwana nemidwebo Kulesi sixhumanisi esilandelayo.
