Ob Qhov Chaw Tshaj Tawm Cov Hluav Taws Xob rau Guitar: 10 Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Txoj haujlwm no yog ib qho yooj yim los tsim, tsim thawj rau dual channel Signal Generator rau guitar thiab lwm yam siv. Nws npog tag nrho ntau ntawm cov ntawv sau guitar (rau koj cov kws ntaus kis las, los ntawm qhib Qis E txoj hlua - 83 Hertz, txog rau 24th kev ntxhov siab ntawm txoj hlua E siab). Nws muaj ob txoj kev sib cais txhua tus tuaj yeem teeb tsa sib cais, thiab koj tuaj yeem hloov pauv tau yooj yim ntawm lawv.

Qhov no yuav muaj txiaj ntsig zoo los pab koj txheeb xyuas cov teeb meem nrog guitar pedals thiab nrog koj lub guitar amp, yam tsis siv koj lub guitar nws tus kheej. Yog tias koj nyiam tsim cov teebmeem guitar no yuav muaj txiaj ntsig kom muaj thaum lub sijhawm tsim tsev- thiab ntsuas theem ntawm koj cov txiaj ntsig guitar.

Nws muaj ob qhov kev tawm:

• 1/4 inch guitar ntxiv rau yog li koj tuaj yeem txuas lub cuab yeej rau lub tshuab ntaus suab paj nruag lossis ob lub tshuab ntaus suab paj nruag
• Ib khub ntawm cov ntawv liab thiab dub khi, uas koj tuaj yeem ncaj qha txuas rau cov xov ntawm cov txiaj ntsig guitar koj tuaj yeem tsim, lossis tuaj yeem txuas rau hauv ib khub ntawm kev xeem ua.

Kuv tsim qhov no nrog cov kev txwv hauv qab no hauv siab:

• Yuav tsum yog thawj. Kuv yuav tsis mus yuav qee lub rooj tsav xwm ua ntej los ntawm aliexpress, npuaj nws hauv rooj plaub, thiab hu nws "Maker project" rau koj.
• Tsim los rau tus pib kom tuaj yeem tsim nws yam tsis muaj kua muag.
• Npog tag nrho ntau ntawm cov ntawv sau guitar thiab tom qab ntawd qee qhov
• Tus neeg ua haujlwm tsis zoo nkauj. Tsis yog qhov no tsis yog li cas kuv $ 150 txog $ 200 kev cai ntaus nrig kuv muag zoo. Lol
• Yooj yim, ua haujlwm tau yooj yim: peb lub pob tswj thiab hloov. Guitarists yuav paub tam sim ntawd yuav siv nws li cas.
• Cov lej tsawg heev suav thiab txhua ntu yog ib qho yooj yim thiab tau txais. Ob peb resistors thiab capacitors thiab ib tus nti.
• Foolproof tsim, tsawg heev uas tuaj yeem mus tsis raug. Muaj zog.
• Ua haujlwm roj teeb ntsiag to Ua haujlwm ntawm (2) cov roj teeb AA ntau; tsis tas yuav ntsaws dab tsi rau ntawm phab ntsa.
• Ob txoj hauv kev sib cais yog li koj tuaj yeem teeb tsa ob daim ntawv sib txawv lossis suab nrov, thiab hloov ntawm lawv
• Tsis muaj microcontrollers, tsis muaj Arduino, tsis muaj programming, tsis muaj software. Kuv nyiam hom lus programming yog laug.
• Kos cov microwatts ntawm qhov tam sim no. (2) AA roj teeb yuav tsum nyob ntev ntau lub hlis txog rau xyoo, txawm tias koj tsis hnov qab kaw nws. Tus qauv tsuas yog thim 33 microamps ntawm tam sim no.
• Npog qhov hluav taws xob tso tawm ntau ntawm txhua qhov tsis sib xws ib puag ncig thiab khaws cov khoom khaws cia los ntawm cov kws tsim khoom siv suab paj nruag (Fender, Gibson thiab lwm yam), dhau los ntawm cov khoom tuaj tom qab muaj zog tshaj plaws.
• Peak voltage kwv yees li 1.5 Volts AC (RMS) uas suav nrog cov khoom nqa tuaj ib yam nkaus. Yuav tsis ua mob rau koj lub guitar amp lossis guitar pedals.
• Ceev kom ua. Kwv yees li 1-2 teev tej zaum tsawg dua.

Cia peb pib tsim nws.

Kauj Ruam 1: Me Me Me ntawm Acoustics (xaiv tau)

Tus ntaus guitar yog ib qho cuab yeej uas npog tsib lub suab paj nruas. Q qhib qis E txoj hlua (hu ua E2 ntawm daim duab) muaj qhov siv zaus ntawm 82 Hertz (cyles per second). Qhib siab E hlua (E4 ntawm daim duab) yog kwv yees li 330 Hz. Kev ntxhov siab 24th ntawm txoj hlua E siab (E6 ntawm daim duab, siab npaum li cov guitars feem ntau mus) peb 1, 319 Hertz.

Ntawm lub npov qauv kuv tsim los qhia rau koj Kuv tau cim tseg qee qhov ntawm cov zaus no nrog Sharpie ntawm lub ntsej muag ntawm lub vaj huam sib luag tswj

Txoj haujlwm koj tab tom tsim los npog ntau zaus txog li 82 Hz txog 4, 500 Hertz, lossis ib thiab ib nrab octaves saum toj saud siab tshaj ntawm tus ntaus guitar - txawm li cas los xij qhov siv tau ntawm cov cuab yeej no yog txog E6.

Ib lub kauj qub passive guitar tuaj tos zoo li koj yuav pom ntawm Fender Telecaster lossis Stratocaster tso tawm txog 100 millivolts (millivolt yog 1/1, 000 ntawm volt). Qee lub khw muag khoom tom qab kub tau tso tawm txog 190 txog 300 milivolts (mV). Lub suab nrov zoo li Gibson pib ntawm 200 mV. Kev khaws khoom tom qab tuaj yeem nce mus txog 400-500 mV ntau piv txwv li qhov kub tshaj plaws DiMarzio lossis Seymour Duncan tuaj tos yog nyob ntawm thaj tsam ntawd rau lub humbucker. Lub tshuab hluav taws xob teeb liab no npog thaj tsam ntawd. Yog tias koj saib daim duab ntawm lub npov qauv uas kuv ua, kuv tau cim lub ntim tswj hauv 100 mV nce ntxiv. Yog peb txhua tus paub yog tias koj tsoo cov hlua nyuaj heev koj tuaj yeem tsim qhov siab tshaj tam sim ntawd txog 1, 000 mV (ib Volt) tab sis rau lub tshuab hluav taws xob teeb liab koj xav siv ntau yam.

Koj tau tso cai los tsim ib qho ntawm no rau koj tus kheej tsis yog lag luam siv thiab kuv ntseeg tias koj yuav pom nws muaj txiaj ntsig; tseem kuv khaws cov cai tshwj xeeb rau kev lag luam muag cov no los ua ke lossis hauv cov khoom siv, hauv qee lub sijhawm tom qab raws li kuv xav tau,

Kauj Ruam 2: Nov yog Lub Rooj Tswjhwm Saib Xyuas Circuit, Daim Ntawv Teev Npe Tshooj thiab Daim Duab Daim Duab (txheej txheem) rau Txoj Haujlwm no
