Nov yog peb thawj qhov haujlwm nrog ATtiny85; lub hnab tshos digital yooj yim (hauv kev koom tes nrog J. Arturo Espejel Báez).
ATtiny85 yog qhov ua tau zoo thiab lub zog qis microcontroller. Nws muaj 8 Kbytes ntawm lub program flash nco. Vim qhov no, qhov kev sib tw hauv txoj haujlwm no yog txhawm rau txo qhov kev zov me nyuam, vim tias kev sib txuas lus tau yooj yim heev, ua tsaug rau I2C raws tu qauv.
Khoom siv
Rau Compass:
- ATtiny85
- HMC5883L Magnetometer
- SSD1306 I2c 0.96 "128x64 OLED Zaub
- Xauv tus kheej lub xwmfab khawm hloov
- 3.7V 300mAh Lipo Li-polymer Roj teeb
- Cov ntaub ntawv luam tawm 3D (2 ntu, thov nrhiav STL txuas)
Rau Charger:
- Ob daim PCB; 17x10mm thiab 13x18mm
- Cov ntaub ntawv luam tawm 3D (2 ntu, thov nrhiav STL txuas)
- Micro USB 5V 1A TP4056 Lithium roj teeb charger module
Kauj Ruam 1: Txoj Haujlwm
Nws yog qhov tsim nyog los thauj cov haujlwm AB.ino mus rau ATtiny85 ua ntej txuas nws hauv kab hluav taws xob. Txog qhov no, koj tuaj yeem ua raws ib qho ntawm cov lus qhia hauv is taws nem, xws li https://www.instructables.com/id/DIY-Attiny-Progr… Txhawm rau sau qhov program, koj yuav tsum teeb tsa lub tsev qiv ntawv ssd1306 los ntawm Alexey Dynda, muaj nyob hauv
Kauj ruam 2: Circuit Court
Kauj Ruam 3: Txuas lub ATtiny85
Nws yog qhov yooj yim los txiav cov pins uas tsis siv ntawm ATtiny ua ntej siv cov khoom siv.
Npaj ob 10-cm khub ntawm xaim los ntawm kev tshem ob 2-mm ntu ib nrab thiab cais los ntawm kwv yees li 5 mm los ntawm ib leeg, raws li qhia hauv daim duab 1 thiab 2. Cov kab laug sab ib seem ntawm thawj kab ntawm kab (A) rau SDA (tus pin 5) thiab lwm ntu rau SCL (tus pin 7) raws li qhia hauv daim duab thib 3. Nrog rau lwm khub ntawm cov xov hlau (B), txuas ib kab rau GND (tus pin 4) thiab lwm tus rau +V (tus pin 8), zoo li hauv daim duab thib 4.
Kauj Ruam 4: Txuas lub OLED Display
Muab plaub txoj xov hlau tso rau ntawm ib sab ntawm ATtiny (SDA, SCL, +V, thiab GND) mus rau qhov sib raug zoo sib xws ntawm OLED zaub thiab muab lo rau hauv rooj plaub. Tiv thaiv lub rooj tsavxwm nrog daim kab xev insulating.
Kauj Ruam 5: Tso Cov Chaw Sib Tham Charger
Siv ob lub xov hlau los ntawm tus txiv neej header tus pin txuas. Quav txhua tus tsim ib tus nuv raws li hauv thawj daim duab. Ntxig ib qho rau sab nraub qaum ntawm rooj plaub, thiab lwm qhov hauv qab lub hau raws li qhia.
Kauj Ruam 6: Txuas HMC5883L
Kaw cov HMC5883L magnetometer rau hauv qab lub hau raws li qhia. Solder SCL thiab SDA cov xov hlau los ntawm ATtiny mus rau qhov sib tiv tauj ntawm lub tshuab nqus hlau, khawm lub xov tooj sib txuas them thiab txuas rau GND tiv tauj. Siv lub +V thiab GND xov hlau los ntawm ATtiny mus rau cov neeg sib tham. Tiv thaiv daim phiaj hlau nplaum nrog daim kab xev insulating.
Kauj Ruam 7: Txuas Lub Roj Teeb
Solder tus ncej tsis zoo ntawm lub roj teeb rau tus pin 4 ntawm ATtiny, thiab qhov zoo rau lub charger tiv tauj nyob rau sab ntawm rooj plaub. Ntxiv xaim los ntawm qhov kev sib cuag no mus rau qhov hloov pauv (saib cov kauj ruam tom ntej).
Kauj Ruam 8: Txuas lub Hloov
Muab cov xaim hluav taws xob los ntawm lub roj teeb txuas mus rau ib qho kev sib cuag, thiab tom qab ntawd lwm tus mus rau +V kev sib cuag ntawm lub tshuab ntsuas hluav taws xob. Tam sim no koj tuaj yeem sim Compass thiab lo lub hau hauv qab.
Kauj ruam 9: Calibrating
Qhov kev zov me nyuam AB.ino muaj qhov ntsuas ntsuas tsis siv neeg. Koj tsuas yog yuav tsum tig thiab tig lub koob yees duab 360º raws li qhia hauv video.
NCO TSEG! Tsis txhob txuas ob qho tib si sab nraud li qhov no yuav ua rau luv luv Circuit Court.
Kauj ruam 10: Charger I
Txiav ob daim PCB ntawm 17 mm x 10 mm thiab 13 mm x18 mm. Laum ib lub qhov me me uas sib phim nrog lub qhov nyob puag ncig 3D luam tawm ib feem, hla cov hlau hla thiab muab nws tso rau. Kaw cov PCB raws li qhia hauv daim duab.
Kauj ruam 11: Charger II
Muab cov xaim xaim tso rau hauv 17x10mm PCB daim thiab hla nws pov rau hauv qhov 3D luam tawm ib feem. Kua nplaum nws raws li qhia.
Kauj Ruam 12: Charger III
Haum thiab lo cov 3D luam tawm ib feem raws li qhia thiab muab cov hlua txuas rau lub roj teeb them nqi hluav taws xob. Cov hlau xaim nyob hauv qab yog qhov tsis zoo. Tam sim no koj tuaj yeem them lub roj teeb ntawm lub roj teeb nrog lub mini USB cable.
