Nyob zoo!
Ntawm no kuv xav qhia koj yuav ua li cas thiaj ua rau koj tus kheej lub mloog pob ntseg bluetooth wireless. Kuv qhov kev mob siab rau ua txoj haujlwm no yog qhov tseeb tias muaj ntau qhov tsis zoo bluetooth lub mloog pob ntseg uas kuv tau yuav tsis ntev los no, yog li los ntawm kev ua kuv tus kheej kuv tuaj yeem hloov kho thiab txhim kho txhua yam uas kuv xav kom nws ua. Dhau li, kuv kuj muaj tus kheej lub tshuab luam ntawv 3D uas ua rau txoj haujlwm no zoo siab dua thiab tuaj yeem kho tau ntau dua.
Lub mloog pob ntseg no (BK8000L Chip) nta bluetooth 2.1+ EDR ua raws, A2DP v1.2, AVRCP v1.0 thiab HFP v1.5 uas tsis zoo li kuv xav tsis thoob los ntawm kev saib lwm cov qauv hauv online uas txhawb nqa bluetooth 4.+ xws li cov txuj ci CSR chips. Tab sis qhov kawg ua rau kuv txaus siab vim tias nws tsuas yog txuas nrawm, ua haujlwm zoo li ntxim nyiam, siv tau, thiab tau kawg qhov tseem ceeb tshaj plaws, suab zoo dua li kuv tau yuav yav tas los. Txaus siab rau cov yeeb yaj kiab kuj tseem ua tau vim tias lub latency ntawm lub bluetooth no yog kwv yees li qis dua 100ms. Qee qhov kev ntsuas ntsuas yuav txuas nrog hauv qab no
Muab qhov tseeb tias txoj haujlwm no nyuaj rau cov pib, kuv qhia koj kom ua siab ntev thaum ua qhov no vim tias qhov no xav tau kev paub zoo li 3d luam ntawv, pcb ua, siv tshuaj txhuam, thiab ua qauv 3D. Cia peb dhia dej hauv!
Kauj Ruam 1: Npaj Cov Khoom
Cov Cuab Yeej:
- 3D Tshuab Luam Ntawv
- Laserjet Tshuab Luam Ntawv
- Ntsia Hlau (-)
- Solder
- Txiab
- Hlau
- Multimeter
Cov ntaub ntawv:
- BK8000L Chip (Los ntawm Aliexpress, thiab lwm yam)
- Wired Headset/Earphone (Tau qhov zoo tshaj plaws uas koj tuaj yeem them taus)
- Lipo Roj teeb 260mah (tuaj yeem kho tau)
- TP4056
- Laub Khawm (smd)
- Toggle Hloov (smd)
- Resistor 110 ohm loj 1206 (3x 330 ohm paralleled)
- Resistor 10k rau TP4056 treshold tam sim no
- Daim ntawv yees duab
- PCB Board (1 hli tuab)
- Soldering tin thiab flux
- PLA Filament
Kauj Ruam 2: Ua Koj Li PCB Board
- Nruab qhov software wizard software thiab ua raws cov lus qhia
- teeb koj cov ntawv rau iav (SMD)
- Luam cov txheej txheem PCB saum toj no (BK8000L Module 3.cwz)
- Txiav koj lub Rooj Tswjhwm Saib PCB raws li qhov tsim ntawm PCB tsim
- Kho koj cov hlau kub me ntsis hauv qab qhov siab tshaj plaws thiab pib ironing lub rooj rau kwv yees. 5-8 feeb (ceeb toom: ua ntej, tso daim duab duab thiab ua kom sov nws los ntawm ob sab mus rau qhov kev pab them nqi tag nrho, tom qab ntawv siv qee qhov siab thaum koj hlau nws (nrog lub ntsis) hauv kab ntsug, kab rov tav, thiab kab pheeb ces kaum. thaum koj iron, tus number case yuav tawg)
- Tsau PCB hauv dej li 2-3 feeb
- Rub daim ntawv kom txog thaum pom tus number case, tseem qhuav nws kom pom tias muaj qee cov ntawv seem
- Siv ferric chloride (FeCl3) daws kom txog thaum PCB tsim.
- Tso koj cov khoom siv nrog cov laug (BK8000L Chip, tus tiv thaiv, tus poj niam tus pin lub taub hau, toggle hloov, laub khawm, Lipo Roj teeb)
- Kuaj rau txhua txoj kab luv nrog w/ multimeter
Kauj Ruam 3: Kho Koj Lub Pob Ntseg
Ntu no, koj xav tau AutoCAD software rau rov tsim kho kuv lub (wireless 3.dwg). Kuv kuj muab koj cov stl. cov ntaub ntawv (3a thiab 3b) saum toj no. Koj tuaj yeem hloov kho qhov dav, sib xws ntawm koj cov khoom siv, thiab lwm yam. Tom qab koj npaj nrog koj tsim, 3D Luam nws
Kauj Ruam 4: Muab Nws Txhua Qhov Ua Ke
Thawj daim duab qhia pom 3D Luam Ntawv (2 daim) rau sab saum toj thiab hauv qab kaw, tom qab ntawv daim duab tom ntej qhia txog cov roj teeb ua tiav thiab cov khoom siv raws li qhia ua ntej. Kaw ob qho tib si ntawm 3D Luam tawm daim thiab lub mloog pob ntseg zoo li tau hais los saum no. Nws yog qhov tsim nyog yog li koj cov khoom siv thiab cable yuav tsis poob tawm. Daim duab kawg qhia pom hauv qab kaw nrog them chaw nres nkoj (+ & -). YUAV TSUM tsis thim rov qab thaum koj tsub nqi tam sim no hloov kho TP4056.
Kauj Ruam 5: Ntsuas thiab Xeem
- Kev ntsuas suab los ntawm kev sib piv cov ntaub ntawv mp3 tiag tiag thiab kaw qhov tshwm sim ntawm lub mloog pob ntseg bluetooth (lub xov tooj raws li lub kaw lus yog li qhov tshwm sim yuav cuam tshuam los ntawm lub xov tooj mic lossis ib puag ncig)
- Kev ntsuas latency los ntawm kev kaw cov vis dis aus thiab bluetooth ntawm tus xa mus ib txhij nrog lub vijtsam kaw thiab kaw lub kaw lus (Cov txiaj ntsig: qeeb latency <100ms)
-
Amperage ntsuas los laij lub roj teeb lub neej:
- Bluetooth sniffing: 30-50mA
- Bluetooth ua suab: 55-60mA Sib npaug rau 0.222 Watt
- Bluetooth ncua: 25mA
- Bluetooth tsis ua haujlwm: tsis muaj qhov tshwj xeeb
- 260mah 3.7v Roj teeb sib npaug rau 0.962 Watt Teev
- Theoretical Battery Life: 0.962/0.222 = 4.33.. teev suab paj nruag ua si ntawm qhov ntim siab tsis tu ncua
Kauj Ruam 6: Kev Txhim Kho Yav Tom Ntej
Yog lawm nws yog! vam tias koj nyiam kuv qhov bluetooth headset project.
- Rau kev txhim kho yav tom ntej kuv xav txhim kho qhov zoo thiab roj teeb los ntawm kev siv cov khoom tsim nyog tau txais txiaj ntsig zoo: CSR86xx
- Kuv kuj zoo siab txog fitbit-zoo ib yam them nyiaj dock rau txoj haujlwm yav tom ntej rau kev ntseeg siab hauv kev them nyiaj
Hloov tshiab >> Them nyiaj dock yog tam sim no ua tau!
5/13/19
Tsuas yog hloov tshiab sai rau lub fitbit zoo ib yam li lub charger uas kuv tau tsim lub lim tiam no. Qhov kev tsim no tig tawm zoo heev thiab ua rau lub mloog pob ntseg bluetooth them txhua lub sijhawm. Raws li koj tuaj yeem pom los ntawm cov duab saum toj no, tsuas muaj 2 ntu: Lub cev thiab lub nraub qaum. TP4056 yooj yim haum rau hauv lub cev thiab tsuas yog xav tau me ntsis soldering rau tus pin them thiab npaj kom nkag los ntawm lub nraub qaum.
Qhov xwm txheej, kuv tau tsim lub cev sab saum toj kawg nkaus nyias thiaj li pom lub teeb pom kev los ntawm TP4056 dhau los thiab muab nws qhov taw qhia zoo txawm tias nws tau them lossis tsis. Ntsuab kom puv/tsis thauj khoom thiab Liab rau them.
