2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Phaser guitar pedal yog cov suab paj nruas uas faib cov teeb liab, xa ib txoj hauv kev los ntawm Circuit kom huv thiab hloov theem thib ob. Ob lub cim qhia tom qab sib xyaw ua ke thiab thaum tawm ntawm theem, rho tawm ib leeg tawm. Qhov no tsim lub suab me ntsis zoo ib yam li flanger lossis pib-wah.

Cov nyhuv no ua rau tus neeg xub ntaus lub scene nyuaj heev hauv xyoo 1970 thiab ntxiv ib lub npe tshwj xeeb ntawm outerspaciness mus rau kaum xyoo lom zem heev. Nrhiav kom rov muaj lub suab qub qub qub, Kuv tau tsim qhov qub 4-theem phaser. Cov pedal tshwj xeeb no yog qhov yooj yim heev thiab tso cai rau koj los kho qhov tob thiab tus nqi ntawm cov theem. Thaum cov tswj tsis tau liab qab, koj tseem tuaj yeem hu nws los tsim qhov hloov pauv maj mam rau lub guitar, lossis crank cov xov tooj txhua txoj hauv kev kom puv-nplua nplua suab.

Kauj ruam 1: Cov ntaub ntawv

(x5) LM741 (x4) 2N5457 FET (x3) 2N3904 transistor (x1) 100K trim potentiometer (x1) Lub hom phiaj PCB (x1) DPDT pushbutton (x2) Aluminium pob qhov rooj (x2) 50K potentiometers (x2) 510K resistors * (x1) 390K resistor (x2) 150K resistors * (x11) 100K resistors * (x1) 47K resistors * (x1) 43K resistor (x4) 22K resistors * (x2) 10K resistors * (x1) 5.1K resistor * (x2) 2.2K resistors * (x1) 220uF capacitor ** (x1) 22uF capacitor ** (x1) 10uF capacitor ** (x1) 0.33uF capacitor (x3) 0.15uF capacitors (x1) 0.022uF capacitor *** (x4) 0.01uF capacitors * ** (x1) 0.001uF capacitor *** (x1) 7.5V Zener Diode (x2) Lub tso suab tso suab (x1) 9V roj teeb snap (x1) 9V roj teeb (x1)

* Cov pa roj carbon zaj duab xis resistor cov khoom. Tsuas yog cov khoom siv tsim nyog rau txhua qhov cim npe. ** Cov khoom siv hluav taws xob hluav taws xob. Tsuas yog ib pob khoom tsim nyog rau txhua qhov cim npe *** Cov khoom siv hluav taws xob ua hluav taws xob. Tsuas yog ib pob khoom tsim nyog rau txhua daim ntawv lo.

Thov nco ntsoov tias qee qhov txuas ntawm nplooj ntawv no muaj Amazon cov koom nrog txuas. Qhov no tsis hloov tus nqi ntawm ib yam ntawm cov khoom muag. Txawm li cas los xij, Kuv khwv tau nyiaj me me yog tias koj nyem rau ntawm ib qho ntawm cov txuas thiab yuav dab tsi. Kuv rov nqis peev cov nyiaj no rau hauv cov ntaub ntawv thiab cov cuab yeej rau cov phiaj xwm yav tom ntej. Yog tias koj xav tau lwm txoj kev tawm tswv yim rau tus xa khoom ntawm ib qho ntawm cov khoom, thov qhia rau kuv paub.

Kauj ruam 2: Phaser Schematic

Tsim lub Circuit Court raws li tau teev tseg hauv schematic. Tsis txhob txhawj xeeb txog qhov muaj zog, lub suab sib txuas, lossis hloov pauv rau lub sijhawm tam sim no. Cov no yuav raug teeb tsa tom qab.

Nco ntsoov tias koj tab tom nyem ntau cov khoom siv rau hauv qhov chaw me me, yog li nteg cov khoom tawm thiab npaj ua tib zoo ua ntej koj pib siv cov laug.

Txawm hais tias qhov no yuav zoo li muaj kev cuam tshuam loj heev ntawm cov khoom siv hluav taws xob sib piv, lub Circuit Court yog qhov yooj yim me ntsis. Lub teeb liab guitar xub nkag mus rau theem preamp. Nws yog tom qab ntawd sib cais xws li lub teeb liab huv mus ncaj mus rau lub qhov tso tawm thiab lub teeb liab mus rau theem hloov pauv mus rau ntu 4 LM741 op-amps uas tsim cov lim tag nrho. Lub lim dej no yog qhov tseem ceeb uas hloov pauv theem raws li lub teeb liab los ntawm LFO (zaus qis oscillator).

LFO yog suav nrog tus thib 5 LM741 op-amp hauv Circuit (thiab ib puag ncig Circuitry). Tus nqi ntawm LFO raug tswj los ntawm 50K lub zog ntsuas hluav taws xob. LFO tom qab ntawd muab CV (tswj qhov ntsuas hluav taws xob) mus rau txhua qhov dhau los lim los ntawm 2N5457 FETs. Qhov kev hloov pauv no ua rau lub teeb liab hauv lub lim hloov mus rau theem ntawm LFO.

Lub suab teeb liab los ntawm txhua lub lim lim tom qab ntawd mus rau taw taw. Yog tias qhov hloov pauv qhib, tsuas yog lub teeb liab huv ua rau nws mus rau lub qhov tso tawm. Yog tias qhov kev hloov pauv raug kaw theem hloov pauv lub teeb liab tau tso cai hla mus rau qhov tso tawm thiab sib xyaw nrog lub teeb liab huv. Txawm li cas los xij, ua ntej lub teeb liab hloov pauv tau sib xyaw nrog lub teeb liab huv nws dhau los ntawm 50K lub zog ntsuas uas txiav txim siab ntau npaum li cas ntawm cov cim qhia tau sib xyaw ua ke.

Los ntawm qhov ntawd, nws tawm mus rau amp thiab tus so yog keeb kwm.

Kauj Ruam 3: Txuas Hlau

Txuas 6 xov hlau rau ob lub hwj chim txuas rau lub rooj tsav xwm hauv Circuit.

Tsis tas li, txuas 6 xov hlau mus rau lub rooj tsav xwm hluav taws xob rau lub suab ntsaws.

Thaum kawg, txuas cov hlua hluav taws xob liab los ntawm lub hwj chim txuas mus rau qhov chaw tsim nyog ntawm daim phiaj hluav taws xob.

Kauj Ruam 9: Hlau Nws

Hlau txuas lub rooj tsav xwm hluav taws xob mus rau lub suab tso suab, lub zog loj, hloov taw thiab lub roj teeb 9V raws li tau hais tseg hauv cov txheej txheem.

Kauj ruam 10: Suab

Mount lub suab tso rau hauv lub cev ntawm rooj plaub.

Kauj ruam 11: Lub zog

Txuas lub roj teeb mus rau 9V roj teeb snap.

Kauj Ruam 12: Kaw Qhov Case

Kaw lub qhov rooj uas siv cov cuab yeej tsim nyog.

Kauj Ruam 13: Cov pob qhov rooj

Nias lub pob qhov rooj mus rau lub zog potentiometer.

Kauj ruam 14: Plug thiab Ua Si

Txuas lub guitar mus rau hauv lub suab-hauv lub suab thiab lub amp rau hauv lub suab tawm jack.

Tam sim no koj yuav tsum npaj kom pob zeb tawm.

Koj puas pom qhov no muaj txiaj ntsig, lom zem, lossis lom zem? Ua raws @madeineuphoria kom pom kuv cov phiaj xwm tshiab kawg.
