Cov lus qhia no yuav qhia koj yuav ua li cas thiaj tsim tau Vario pheej yig, uas tuaj yeem hais lus qhov siab thiab tau kawg xa ntau lub suab nrov thaum hloov qhov siab ntawm koj lub dav hlau. Qee qhov tshwj xeeb: - lub suab thiab lub suab - siv koj tus kheej (yoj-) piv txwv hauv koj cov lus - yoj -piv txwv khaws cia ntawm sd -card - hloov ntawm rc ntawm qhov siab -lub suab/vario -tone/tawm - tsis siv neeg tshaj tawm ntawm qhov siab hauv ib puas meter cov kauj ruam - tso tawm suab ntau zaus, koj tuaj yeem siv koj tus kheej lub xov tooj cua, PMR, FRS, tus saib xyuas menyuam lossis ib yam dab tsi - Microcontroller yuav hloov lub xov tooj cua thiab "nias" TX -khawm - siv 5 Volt los ntawm rc -receiver Ntawm no yog kuv thawj Video, lub suab tso tawm yog hauv German tsis tau, tab sis kuv yuav tso cov suab lus Askiv ua piv txwv

Kauj Ruam 1: Yam Koj Xav Tau

Koj xav tau dab tsi: - Parallax Propeller Microcontroller (-board) kuv siv Crouu's CpuBlade vim tias nws yog pawg thawj coj saib me tshaj thiab lub teeb: https://www.clusos.com/home/1994.html - (Micro-) SD Card + Socket - Siab Sensor Modul MS5611 ntawm Breakoutboard - qee lub kaus mom thiab cov neeg tawm tsam, saib cov phiaj xwm - koj tuaj yeem siv kab txaij lossis kuv txheej rau PCB - rau xov tooj cua txuas: kuv siv PMR/FMR Walkie Talkie (15-20 $/Euro rau Ebay) txog 5 km nrug - Programmer FTDI USB -TTL (piv txwv li cov xav tau rau Arduino) - nthwv dej piv txwv thiab firmware, saib cov kauj ruam tom ntej

Kauj Ruam 2: PCB lossis Stripboard

Yog tias koj xav siv kab txaij los yog cov zoo li ntawm no yog daim duab qhia chaw thiab koj tuaj yeem hla cov kauj ruam tom ntej txog PCB. Thaum siv kuv li PCB ntawm no yog cov lus qhia zoo

Kauj Ruam 3: PCB

-PCB-Layout yog 1Bit-BMP-Dimension: 51mm x 28mm-qhov kev xaiv zoo tshaj plaws rau SD-Socket yog lub micro-version, thaum siv lub qhov (socket) "loj" koj yuav tsum sib dhos nrog qhov chaw me ntsis ntawm qhov (socket) thiab pcb. - Cov ntaub qhwv rau smd lossis cov hlua khawm thiab cov tiv thaiv, siv sab hauv qab rau qhov txuas txuas- tsis txhob hnov qab txuas 3, 3 V ncoo los ntawm sd-socket rau 3, 3 V tus tswj hwm los ntawm MS5611-board (saib cov khoom sib dhos/cov phiaj xwm)

Kauj ruam 4: Programming Vario thiab Npaj SD-daim npav

Yog tias kho vajtse tiav peb tau nyem Eeprom ntawm lub tshuab hluav taws xob microcontroller. Koj yuav xav tau cov cuab yeej kiv cua. Tom qab teeb tsa pib lub cuab yeej, txuas FTDI programmer rau usb thiab pcb, qhib lub binary kuv ntxiv thiab ntsaws rau hauv Eeprom. Cov Cuab Yeej Siv Hluav Taws Xob tau siv yooj yim heev, cov chaw nres nkoj com yuav cia li luam theej duab rau txuas nrog lub tshuab hluav taws xob sib txuas. Tam sim no nws yog lub sijhawm los npaj SD-daim npav nrog cov ntawv ua piv txwv. - Ua daim npav nrog FAT. - Txhua qhov piv txwv yuav tsum tau muab tso rau hauv cov hauv paus ntawv - Kuv ntxiv cov lus hais ua lus Askiv zoo, saib zip file - Koj tuaj yeem rub cov qauv zoo los ntawm no lossis ntawm no - 8 ntsis lossis 16 ntsis txog 44, 1khz xav tau - thaum siv koj tus kheej lub npe hloov pauv hauv 1.wav, 2.wav …….. (saib zip file) - SD -card max. loj 2GB !!! -Thaum siv lub pcb nrog lub qhov (socket) ib txwm tsis siv micro-sd-lub qhov (socket) koj xav tau lwm lub khoos phis tawj vim tias lwm tus pin-pin rau DI tau siv!

Kauj Ruam 5: Txuas Vario Nrog Xov Tooj Cua

Nov yog qhov piv txwv ntawm yuav txuas Vario li cas rau Walkie-Talkie pheej yig kuv yuav ntawm ebay rau 15 $. Muaj tsib qhov kev sib txuas ua tiav: - 5V muab hluav taws xob rau lub roj teeb tiv tauj los ntawm xov tooj cua, tseem hauv av - tshem lub tshuab electret microphone los ntawm xov tooj cua thiab txuas "tus pin kub" rau mic los ntawm vario - kub pins los ntawm lub zog- thiab ptt- khawm (xov tooj cua) rau vario-pins lub zog thiab ptt (qhov no xav tau rau kev hloov pauv ntawm xov tooj cua) saib kuj ntawm daim duab txuas

Kauj Ruam 6: Cov Lus Qhia Kawg

Kev Xeem:-txuas cov channel dawb los ntawm koj rc-receiver mus rau vario, siv lub fuse (0, 5 A) kom tsis txhob muaj kev pheej hmoo ntawm kev luv, qhov hloov pauv tau los ntawm rc-txais! -rc-transmitter xav tau 3 txoj haujlwm hloov pauv: Pos1 (tawm): PropVario xa tsis muaj xov xwm, xov tooj cua-xa tawm yog tawm Pos2 (nruab nrab): PropVario xa suab qis/siab dua thaum lub dav hlau poob/nce Pos3 (ntawm): PropVario xa qhov siab tiag tiag hauv 'meter' Thaum siv lub dav hlau lub zog hloov pauv hauv xov tooj cua thiab yuav zoo siab tos txais koj nrog kev hais "ok". Tam sim no koj tuaj yeem sim cov suab sib txawv los ntawm kev tsa tus qauv hauv koj txhais tes. Tsis tas li qhov siab teb yuav tsum tau sim. Tej zaum tus rudder txwv los ntawm koj li 3 txoj haujlwm hloov pauv yuav tsum raug hloov kho. Pos 1: 0-20% Pos2: 21-79% Pos3: 80-100% kuv xav tias yuav ntsuas lub meter-meter-kauj ruam tsuas tuaj yeem ntsuas hauv huab cua:-) lawv yuav cia li hais txhua txhua tsib caug meters ntsuas Kev ntsuas yog tias siv xov tooj cua /zaus tau tso cai hauv koj lub tebchaws, qhov no tsuas yog qhov piv txwv piv txwv rau qhov txuas qis. Kuv vam tias koj yuav txaus siab thiab zoo siab los nug koj cov lus nug !!!
