Ntawm no kuv qhia koj yuav ua li cas Ntxiv Mute Button rau koj Auna Mic 900. Auna tab tom siv CM6327A USB audio Interface chip uas muaj kev ua haujlwm tsis sib xws uas lawv txiav txim siab tsis txuas yog li peb yuav tsum ua qhov no los ntawm peb tus kheej.
Tsis teb los tau koj tuaj yeem txuas LED ntawm koj auna rau LED3 Pin. Yog tias koj ua li ntawd LED tom qab tsis txaus ntseeg tias Mic tau ntsiag to.
Rau qhov mod koj xav tau cov hauv qab no:
- 1 x 1 k Resistor
- 1x khawm me me (tsis kom tuab oatherwise nws yuav tsis yooj yim kom tau rooj plaub rov qab dua)
- qee cov xov hlau nyias
- Hotglue
- ib rab hlau nrog ib qho taw tes heev thiab me ntsis
- qee qhov kev paub nrog smd soldering
Yog tias koj xav tau qee cov ntaub ntawv ntau ntxiv txog cov nti koj tuaj yeem nrhiav cov ntawv teev tseg ntawm no.
Kauj ruam 1: Teardown
Ua ntej koj yuav tsum Tear lub Mic kom txog thaum koj tuaj yeem nkag mus rau lub nti. Cov PCB uas tsis muaj cov cim tsuas yog shilding thiab tsis txuas rau ib qho twg thiab sofore tuaj yeem tsuas yog ntswj.
Rau Cov Kauj Ruam tom ntej no koj yuav tam sim no npaj qee cov xov hlau tiag tiag. Kuv siv tsuas yog ib txoj hlua tooj liab tawm ntawm cov xaim tooj liab tso tseg.
Kauj ruam 2: Soldering
Qhov no yog qhov feem ntau triky ntawm tag nrho Project.
Kuv ua ntej tinned tooj liab strands thiab muab sume flux rau ntawm tus pin ntawm nti. Tom qab ntawd kuv hloov cov hlau nrog qee tus tweezers thiab tom qab ntawd nrawm nrawm lawv nrog kuv cov hlau ntawm 300 ° C.
Nco ntsoov soldering xaim rau LED yog nyob ntawm yeem.
Kauj Ruam 3: Ntxiv 1k Resistor thiab Khawm
Rau cov kauj ruam no kuv tau siv 1k resistor rau kuv cov tooj liab. Aferwards kuv ruaj ntseg txhua yam nrog cov xaim hluav taws xob ua shure cov tooj liab liab liab tsis muaj dab tsi luv. Tom qab ntawd kuv muab cov xaim txuas mus rau lwm sab ntawm tus tiv thaiv thiab tseem ruaj ntseg nws nrog cov nplaum. Tsis tas li koj tuaj yeem txuas lub khawm tam sim no tab sis tso kom txaus nyob hauv Cov Hlau kom koj tuaj yeem haum rooj plaub nrog khawm rov qab.
Kauj Ruam 4: Mount Khawm thiab Reasamble Mic
Lwm cov xaim los ntawm khawm yuav tsum tau txuas nrog hauv av. Txog qhov ntawd koj tau muab nws tso rau ntawm txhua qhov hauv paus ntawm PCB tab sis kuv tsuas yog xaim cov xaim thiab ua rau nws nyob ib ncig ntawm cov ntsia hlau thaum rov ua nws dua. Wich Txuas lub pob khawm rau hauv av.
Rau kev teeb tsa lub pob kuv tsuas yog drilled lub qhov me me thiab ruaj nws nrog cov nplaum.
Tam sim no koj tuaj yeem rov hais dua lub mic!
Tab sis nco ntsoov tuav lub mic clamp ua ntej yuav kaw nws, vim tias koj yuav tsis tuaj yeem xaub nws hla lub khawm yam tsis ua rau nws puas tsuaj
Kauj Ruam 5: LED Mod (xaiv tau)
Rau LED mod koj yuav tsum txiav ib txoj kab nrog rab riam stanly raws li sown hauv daim duab. Qhov no yog txoj hauv kev txhawb nqa LED nrog 5v. Tom qab ntawd txuas lub mic thiab txheeb xyuas qhov LED tsis pom kev ntxiv lawm. Tam sim no koj tuaj yeem txuas cov hlau coj mus rau Pad dawb raws li qhia hauv daim duab.
Yeem tau koj tam sim no hloov pauv LED mus rau ib qho liab. Tsis tas li ntawd LED yuav tsis pom kev tam sim no vim tias lub nti tsuas yog tawm 3.3V thiab ntawm qhov tsis zoo ntawm LED yog 450 Ohm Resister txuas nrog. Kom tau txais ib puag ncig uas kuv woud tsuas yog txiav cov negativ xaim ntawm tus coj thiab ntxiv tus nqi qis dua tus tiv thaiv thiab txuas nws ncaj qha mus rau qhov siab.
