Kuv yog tus kiv cua loj ntawm cov khoom siv suab. Txij li qee lub sijhawm kuv tab tom nrhiav qee qhov pheej yig lub tso suab tso suab me me, uas kuv tuaj yeem siv rau kev sim ntawm kuv lwm txoj haujlwm, mloog nkauj los ntawm kuv lub xov tooj thiab lwm yam. Qhov kev xaiv zoo tshaj yuav yog DIY cov khoom siv - suav tag nrho, yooj yim thiab nrawm rau sib sau ua ke. Tshawb nrhiav hauv internet Kuv tau pom qhov no. Qhov ntawd yog qhov kuv xav tau. Nws yog lub tso suab, raws li lub npe nrov thiab yeej tsis tuag LM386 nti. Ib qho ntxiv, nws muaj qhov sib npaug ntawm qhov ntim rau ob txoj hauv kev thiab txhawb nqa ntses bass thaj tsam. Qhov zoo tshaj plaws - nws muaj qhov hloov pauv AC/DC suav nrog - kuv tsis tas yuav tshawb nrhiav qhov tsim nyog thaiv lub zog. Yog li.. Kuv tau hu rau tus muag khoom thiab xaj cov khoom. Nws tuaj nrawm heev - tsuas yog 4 hnub (Lub Tebchaws Yelemees - Switzerland). Lwm qhov zoo - cov khoom siv tsis muaj cov ntawv hauv Circuit Court - txhua lub cuab yeej thiab lawv cov txiaj ntsig tau luam tawm ntawm PCB dub. Hauv cov lus qhia no kuv yuav qhia koj cov txheej txheem sib dhos. Feem ntau hauv cov duab:-)

Kauj Ruam 1: Siv Lub Hwj Huam Fais Fab

Thaum xub thawj kuv tau txiav txim siab muab cov khoom siv hluav taws xob tso rau thiab xyuas seb nws ua haujlwm li cas. Kuv tau muab cov AC/DC hloov pauv, cov fuse tuav, lub taub lim dej, txhaws, qhov taw qhia lub zog LED thiab nws txwv kev tiv thaiv. Kuv kuj tau siv lub tshuab fais fab AC. Nov yog lub sijhawm zoo tshaj tawm:

Muaj qhov txaus ntshai hluav taws xob tam sim no ntawm lub rooj tsavxwm - 220V hauv kuv li (110V tej zaum hauv koj li) Kuv tau theej/tso cov lus qhia kev nyab xeeb ncaj qha los ntawm qhov chaw. THOV NYEEM NYEEM NTAWV THOV:

Ntawm PCB muaj qhov phom sij rau koj lub neej muaj hluav taws xob ntau! Ua tib zoo saib xyuas thaum ua haujlwm nrog lub tshuab ua kom nrov nrov! Lub rooj tsavxwm yuav tsum tau muab tso rau ntawm qhov chaw tiv thaiv hluav taws xob - Tsis txhob tso nws rau ntawm lub rooj hlau tsis muaj yas lossis rwb thaiv cov duab los qhia tuab. Tsis txhob kov lub rooj tsavxwm hauv cheeb tsam cim rau ntawm daim duab. Nws raug pom zoo tias lub rooj tsav xwm hais lus tau teeb tsa hauv cov yas lossis cov ntoo. (Kuv npaj siab yuav muab lub thawv tsim nyog luam tawm 3D los ntawm kuv sai sai ntawm lub xaib no). Yog tias koj xav siv lub tsev hlau - teeb tsa board ntawm qee qhov deb ntawm hauv qab ntawm lub thawv siv spacers

Ua raws li cov lus qhia kev nyab xeeb Kuv tau muab lub rooj tsavxwm tso rau ntawm lub ncoo uas siv roj hmab. Kuv ntsuas cov khoom siv hluav taws xob, uas yog 12V.

Kauj Ruam 2: Soldering Resitors

Kauj Ruam 3: Soldering Ceramic Capacitors

Kauj Ruam 4: Soldering Electrolyte Caps

Tom qab lawv kuv tau soldered IC qhov (socket) - cov yam ntxwv zoo - yog tias lub tshuab hluav taws xob nti kub hnyiab - yooj yim los hloov.

Kauj ruam 5: Soldering cov Connectors

Lub suab tawm tswv yim thiab RCA cov khoom txuas txuas txuas tom ntej.

Kauj Ruam 6: Potentiometers…

Kauj Ruam 7: LM386 Ntxig rau hauv Qhov Ntsuas

Kauj Ruam 8: Cov pob

Cov khoom siv tau los nrog cov pob qhov taub yas rau kev tswj hwm lub zog, tab sis kuv muaj cov txhuas tsim nyog thiab kuv tau hloov lawv.

Kauj Ruam 9: Sib Sau Ua Ke

Kuv coj kuv 25 feeb los ua ke tag nrho cov khoom siv. Kuv sim nws nrog cov hais lus nruab nrab band yooj yim. Txawm nrog lawv lub suab zoo yog qhov zoo. Siv lub tso suab sib npaug potentiometer qhov ntim ntawm ob txoj hauv kev tuaj yeem teeb tsa raws li koj xav tau. Kev txhawb nqa ntses bass thaj tsam kuj zoo. Kuv zoo siab nrog cov khoom siv no - qhov tsuas yog qhov uas kuv yuav tsum tau ua yog nrhiav lub thawv tsim nyog rau lub amp. Tej zaum yog kuv yuav luam tawm los ntawm 3D tshuab luam ntawv. Kuv yuav tsum nrhiav sijhawm los tsim nws hauv OpenSCAD.
