Nyob zoo sawv daws!
Zoo siab txais tos rau kuv cov lus qhia nyob qhov twg hauv qhov kev qhia no kuv yuav qhia koj li cas kuv ua qhov no me me tab sis muaj zog 1 watt lub tshuab tso suab uas yooj yim heev los ua, yuav tsum muaj ob peb yam sab nraud sab nraud thiab ntim rau hauv ntau lub zog rau qhov loj ntawm nws!
Yog li cia peb pib!
Khoom siv
- IC 8002 suab lub zog ua kom nrov IC
- 10k resistors - 2
- 22k resistor - 1
- 0.1uF ceramic capacitor - 2
- Txiv neej header pins
- Veroboard lossis protoboard (lossis kev cai ua PCB rau txoj haujlwm no uas kuv tau tham tom qab hauv qhov kev qhia no)
- 5V fais fab mov (them lub xov tooj ntawm tes ua haujlwm zoo xwb)
- 4 Ohm tus hais lus impedance
- 3.5 hli lub mloog pob ntseg (rau lub suab kom yooj yim ntsaws rau hauv)
- Cov khoom siv Soldering, ntau lub 'meter' thiab cov khoom siv ntxiv.
Kauj Ruam 1: Sib Sau Txhua Qhov
Raws li koj tuaj yeem pom tias txoj haujlwm tsim kho tau yooj yim heev thiab cov naj npawb ntawm cov khoom siv xav tau los ua qhov no yog qhov tsawg heev thiab tuaj yeem yooj yim heev muaj nyob ntawm koj lub khw hluav taws xob hauv nroog lossis tso ib puag ncig hauv koj lub rooj ua haujlwm!
Cia peb txav mus rau qhov kev tsim lub Circuit Court.
Kauj ruam 2: Ua Circuit Court
8002 lub tshuab ua kom nrov yog 8 tus pin IC muaj nyob hauv pob SMD thiab yog li ua rau lub Circuit Court ntawm veroboard yog qhov nyuaj me ntsis. Kuv txiav txim siab los ua qhov teeb tsa hauv Circuit Court thiab tom qab ntawd tsim cov ntaub ntawv gerber tsim nyog thiaj li tuaj yeem tsim cov khoom siv tau yooj yim.
Ntawm no kuv tau txuas daim duab qhia chaw thiab kuv li PCB txheej thaum koj xav siv tib yam.
Nov yog qhov txuas rau daim ntawv teev npe ntawm IC kom yooj yim siv:

Kauj Ruam 3: Tsim PCB
Tom qab tsim cov phiaj xwm, xa tawm cov ntaub ntawv Gerber thiab tsim cov ntaub ntawv tsim nyog rau CNC tshuab, nws yog lub sijhawm kawg los tsim PCB siv cov txheej txheem cais tawm.
Kuv muaj hmoo tau muaj lub tshuab CNC uas ua rau kuv txoj haujlwm yooj yim heev thiab kuv tau txais PCB sai sai. Koj ib txwm tuaj yeem ua koj tus kheej PCB thiab ua rau lawv los ntawm txheej txheej ntawm kev xaj lawv los ntawm lub tsev tsim khoom lossis txawm tias xaj lawv online online niaj hnub no.
Kuv tau ua 2 lub rooj sib txig sib luag zoo ib yam yog tias kuv cuam tshuam cov txheej txheem soldering vim tias cov khoom siv SMD ib txwm yog qhov nyuaj thiab peb yuav tsum ua kom ntseeg tau tias tsis muaj qhov luv luv lossis tsis siv qhov tsis zoo yog zam.
Kuv tau ntxiv cov yeeb yaj kiab ntawm CNC milling hauv kev nqis tes hauv cov vis dis aus qhia hauv qab no. Nco ntsoov xyuas nws kom paub meej ntxiv!
Kauj Ruam 4: Ua Kom tiav Cov Txheej Txheem Txheej Txheem
Thawj kauj ruam yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau lub peev xwm ntawm cov khoom sib txuas.
Cov duab hauv qab no qhia tias kuv qhov kev sib tw thaum kawg zoo li cas.
Kauj Ruam 5: Kev Xeem Ntawm Qhov Ua Phem lossis Tsis Xav Tau Kev Sib Txuas
Tom qab txhua txoj haujlwm soldering tau ua tiav, nws yog ib qho tseem ceeb kom ntseeg tau tias peb lub Circuit tsis muaj teeb meem. Txhawm rau ua li ntawd peb tuaj yeem siv lub ntsuas ntsuas nyob rau hauv hom txuas mus txuas ntxiv thiab ntsuas tawm txhua txoj hauv kev uas raug thiab ua kom ntseeg tau tias muaj kev sib txuas zoo. Ib qho luv luv yuav tsum raug kho los ntawm kev tshem cov laug ntau dhau ntawm cov ntsiab lus thiab ntxuav lawv kom huv si txhawm rau tshem tawm cov khoom tsis huv thiab cov dej ntws tawm.
Kauj Ruam 6: Xaiv Cov Hais Lus
Raws li cov ntawv teev tseg, qhov tsis txaus ntseeg ntawm tus hais lus yuav tsum yog 3 ohms, 4 ohms lossis 8 ohms, siv uas peb tuaj yeem tau txais lub zog tso tawm raws li 3 Watts, 2.65 Watts thiab 1.8 Watts feem. Kuv muaj ob peb ntawm lawv pw ib ncig thiab sim lawv nrog lub amp thiab txhua tus ntawm lawv ua haujlwm zoo xwb.
Txog qhov demo zaum kawg kuv siv tus neeg hais lus qub los ntawm lub kaw lus tso suab.
Kauj Ruam 7: Ua Cov Txuas Txuas ntawm Amp
Txhawm rau txuas tus qauv no mus rau lub zog, lub suab thiab tus hais lus, Kuv tau ua cov xov hlau no, ib sab uas tau txuas rau tus poj niam lub taub hau uas haum rau hauv lub taub hau pins ntawm tus qauv. Nrog rau qhov no peb teeb tsa tam sim no ua tiav thiab npaj los sim:)
Kauj Ruam 8: Saib Kawg
Nov yog kuv qhov project tiav. Nws yog qhov me me thiab muaj zog tib lub sijhawm. Hauv kev sib piv, nws yuav luag zoo ib yam li daim npav Indian 2 rupee npib. Koj kuj tseem tuaj yeem siv lub voj voog no siv 3.7 V lithium ion roj teeb raws li IC txhawb nqa qhov ua haujlwm tau zoo. Nco ntsoov tsis pub tshaj qhov siab tshaj qhov pom zoo los ntawm cov ntawv teev npe.
Kuv vam tias koj nyiam qhov kev tsim no!
Zoo siab qhia koj cov lus tawm tswv yim, kev tawm tswv yim thiab kev ua xyem xyav hauv cov lus hauv qab no thiab tsis txhob hnov qab saib cov vis dis aus hauv cov kauj ruam tom ntej, thiab yog tias koj nyob ntawd, txiav txim siab koom nrog kuv li channel thiab.
Txog rau lwm lub sijhawm:)
