Txoj haujlwm no tuaj yeem ua los ntawm milling PCB siv cov ntaub ntawv pom ntawm github lossis siv vero board raws li qhov piv txwv.
Qee qhov yuav tsum tau siv yog li cov cuab yeej ib txwm xav tau:
cam khwb cia hlau
sawv ntsug
hlau xaim
taub ntxhua khaub ncaws
hlau txiav
hlau stripper
pab tes
phom phom
Khoom siv:
paj piez
ntsaws ntsaws
qhov (socket)
pawg vero
IC - LM386N
2 x capacitors - 47uf
roj teeb txuas
9 v pin
suab kab
txuas kab
kub kua nplaum
Kauj ruam 1: Hu rau Microphone
Txiav lub xov hlau (coaxial) rau qhov xav tau ntev (Kuv ib txwm sim tsawg kawg 1 meter).
Seem cov rwb thaiv tsev yas los ntawm qhov kawg ntawm txoj hlua, ntswj cov hlau tooj liab thiab tin (qib 3) qhov xaus ntawm ob lub cores.
Ib kawg ntawm cov tub ntxhais nruab nrab ntawm lub suab cable yuav tsum tau muab tso rau qhov txuas ntawm qhov kawg ntawm lub ntsaws ntsaws, lwm qhov kawg rau nruab nrab (grey) siv lead ua ntawm lub piezo disc.
Cov ntaub thaiv npog (cov tub ntxhais sab nrauv) ntawm lub suab cable yuav tsum tau muab txuas rau ntawm lub tes tsho ntawm lub tsho, lwm qhov kawg mus rau ntug (tooj dag) ntawm piezo disc.
Kauj Ruam 2: Amplifier Circuit
Cov lus piv txwv qhia txog Circuit Court los saum toj saud. Cov cim tooj liab ntawm vero board yuav tsum nyob hauv qab.
Npaj lub vero board los ntawm kev txiav kom loj (7 x 11) thiab txiav cov kab hauv qab IC (LM386 amp nti) nrog rab riam ntse los yog tho me ntsis.
Solder IC qhov (socket) rau lub vero board, nco txog txoj haujlwm ntawm kev faib tawm. IC yuav muab tso rau tom qab.
Txheeb xyuas qhov kev taw qhia ntawm cov capacitors kom ntseeg tau tias lawv tau txuas rau hauv Circuit Court nrog qhov ua kom raug. Lawv yuav muaj kab txaij nyob ntawm ib sab ntawm pob ntawv los qhia tias ceg twg tsis zoo. Qhov kab txaij no cuam tshuam nrog qhov grey ntawm lub voj voog liab nyob hauv qhov piv txwv.
Txuas cov xaim txuas hauv cov haujlwm uas tau qhia hauv kab lus.
Solder lub roj teeb txuas, saib xyuas kom phim qhov zoo (liab) thiab tsis zoo (dub) xov hlau mus rau qhov chaw raug.
Cov kab laug sab zoo thiab tsis zoo txuas cov xov hlau rau lub mloog pob ntseg thiab tso zis rau tus hais lus.
Xyuas kom muaj kev sib txuas hauv av tsis zoo ib yam.
Muab lub amplifier IC tso rau hauv lub qhov (socket). Qhov sib faib hauv lub qhov (socket) thiab IC yuav tsum tau ua raws li qhov kev qhia.
NB: hauv qhov piv txwv;
lub voj voos liab nrog rau qhov grey = polarized electrolytic capacitors 47uf
plaub fab plaub hau nrog 2x4 xiav ceg = DIP lub qhov (socket) / tshuab raj IC LM386
dawb xaim = zoo suab tawm tswv yim
txiv kab ntxwv hlau = qhov zoo tso tawm suab
xaim liab = zoo zog 9v
xaim dub = av tsis zoo
Kauj Ruam 3: Kev Xaiv PCB
Kuv tau ua cov ntaub ntawv gerber uas muaj peev xwm siv tau los tsim cov stencil rau kos cov PCB lossis g-code rau CNC tshuab los zeb PCB. Cov ntaub ntawv tuaj yeem rub tawm los ntawm github. Txoj hauv kev kom muaj neeg nyob hauv PCB no yog zoo ib yam nrog cov lus qhia no. Nco ntsoov tias cov cim uas qhia txog kev taw qhia (zoo thiab tsis zoo).
Kauj ruam 4: Caw caw
Yog tias koj ua qhov ntsuas no thiab muaj cov kaw suab los qhia, thov xa lawv mus rau
Txaus siab rau cov lus tawm tswv yim thiab suab nrov.
