Lub Octave Up guitar pedal yog lub suab nrov zoo li tus ko taw uas tsa koj cov ntawv sau ib qho octave. Qhov no tsis yog lub hom phiaj dav dav uas koj xav siv rau kev ntaus suab paj nruag, tab sis ib qho uas koj xav koom nrog thaum koj tab tom yuav tsoo lub ntsiab lus ib leeg. Tus pedal no nrov me ntsis thiab ntxhi, tab sis tuaj yeem siv tau zoo thaum siv tau zoo. Nov yog lub pedal yooj yim los tsim, thiab twv yuav raug hu yog txoj haujlwm lom zem lis xaus (txawm tias koj tsis tau txais ib tuj ntawm kev siv tawm ntawm nws).

Kauj ruam 2: Txog Circuit Court

Txog Circuit Court
Txog Circuit Court

Lub voj voog no yog ua raws Gus Smalley Txoj Kev Yooj Yim Octave Up pedal thiab Scott Swartz's Octave Screamer, uas tig los raws li ib feem ntawm cov Tube Tube Screamer tus qub. Hauv kuv cov ntawv, Kuv tau coj cov ntsiab lus ntawm txhua peb lub pedals thiab tsim qee yam tshiab-ish. Cov tswv yim rau hauv Circuit Court muaj lub tso suab tso suab uas ua lub luag haujlwm hloov pauv thiab qhib lub zog. Txhawm rau kawm paub ntau ntxiv txog qhov ntawd, txheeb xyuas kuv DIY Guitar Pedal qhia tau. Lub teeb liab los ntawm kev tawm tswv yim ces mus rau DPDT hloov pauv uas ua haujlwm raws li qhov hloov pauv hla qhov tseeb. Qhov no txhais tau tias lub teeb liab huv yuav hla txhua qhov kev sib tham thaum hloov pauv to taub. Yog tias lub Circuit Court tsis hla dhau, lub teeb liab tom qab ntawd dhau los ntawm 0.01uF (C2) lub tshuab hluav taws xob uas ua haujlwm raws li tus qauv nkag nkag. Lub suab tom qab ntawd dhau mus rau qhov tsis hloov pauv ntawm op amp. Kuj txuas nrog rau qhov tsis hloov pauv tswv yim ntawm op amp yog qhov sib faib kev tsheb nqaj hlau virtual. Muab lwm txoj hauv kev, 10K resistors (R1 thiab R2) tsim qhov faib hluav taws xob yooj yim thiab tsim cov av virtual ntawm qhov nruab nrab txuas ntawm qhov faib hluav taws xob. Txhawm rau piav qhia qhov muaj nyob ntawm no xav tau cov ntaub ntawv ntau ntxiv txog op amps dua li kuv xav muab rau ntawm qhov kev sib tham no, tab sis ntseeg kuv tias nws yog tus qauv ncaj ncees. 100uF (C1) thiab 0.1uF (C3) cov khoom siv sib txuas nrog qhov faib hluav taws xob no tsuas yog cov lim hluav taws xob tau npaj los ua kom lub zog hluav taws xob qis. Qhov nruab nrab ntawm qhov faib hluav taws xob tom qab ntawd dhau los ntawm 100K (R3) resistor ntawm nws txoj hauv kev rau qhov tsis hloov pauv tswv yim. Kuv pom tias tus nqi ntawm tus tiv thaiv no tsis tseem ceeb rau lub suab (kom deb li kuv tuaj yeem qhia). Hais ncaj kuv tsis yog 100% paub tseeb tias nws tab tom ua dab tsi, tab sis kuv paub tseeb tias nws xav tau tus tiv thaiv nyob ntawd (vim tias lub Circuit tsis txaus siab thaum kuv tshem nws tawm). Op Op theem tau teeb tsa raws li qhov hloov pauv tau nce tsis hloov pauv qhov siab dhau lub suab nrov. Lub 4.7K (R4) thiab 22uF (C4) txuas nrog rau op amp's inverting input tsim cov lim siab dhau. Lub lim dej no tsuas tso cai rau ntau zaus dhau ntawm qhov pib tshwj xeeb kom dhau thiab tau nce ntxiv. Los ntawm kev kho qhov tseem ceeb ntawm R4 thiab C4, koj tuaj yeem hloov qhov pib txiav tawm. 47K (R5) resistor thiab 1M (R6) potentiometer txuas nrog ntawm qhov tsis hloov pauv tswv yim thiab cov zis hloov kho qhov nce ntawm lub teeb liab. Kuj tseem txuas nrog ntawm qhov hloov pauv tus lej nkag thiab tus pin tso tawm yog ob qho 1N4001 diodes (D1 thiab D2) npaj ua ntej rau tom qab. Cov no ua haujlwm raws li lub ntsej muag clipping diodes uas txhais tau tias lawv pab ua kom qhov txiaj ntsig ntawm lub teeb liab raug txwv rau qhov txwv tsis pub dhau thiab hloov mus rau sab saum toj. Qhov tseem ceeb ntawm cov no tsis yog qhov tseem ceeb tshaj plaws yog tias lawv yog tus qauv silicon diodes. Koj tuaj yeem nyeem ntxiv txog op amp Circuit hauv qab "clipping stage" ntawm Technology ntawm Tube Screamer. Tom qab op amp theem, lub teeb liab dhau los ntawm 22uF (C5) tso tawm tsis thiab tom qab ntawd 1K (R7) resistor. Tus tiv thaiv kab mob no ua haujlwm kom yooj yim qis qib ntawm lub teeb liab me ntsis. Tus hloov pauv (T1) thiab 1N34A germanium diodes (D3, D4) suav nrog kev hloov pauv yoj tag nrho. Qhov rectifier no yog qhov ua haujlwm octave tshwm sim. Yog vim li cas qhov hloov pauv yoj ob npaug ntawm lub octave yog vim nws coj txhua qhov tsis zoo ntawm AC lub teeb liab thiab tig nws hla txoj kab tsheb ciav hlau nruab nrab kom ua ob zaug nws zoo li DC teeb liab. Hauv lwm lo lus, qhov yoj yoj ntawm kev ceeb toom tshwm sim ob zaug ntau zaus. Yog li, txij li muaj ob zaug ntau dua ntawm lub teeb liab, qhov zaus ntawm lub teeb liab nce mus txog ib qho octave. Nws yuav tsum tau sau tseg tias tsis muaj teeb meem koj ua dab tsi hauv seem ntawm lub Circuit Court, vim tias yuav ua li cas tag nrho yoj rectifier ua haujlwm, nws tsuas yog ib txwm nce lub teeb liab ib zaug xwb octave. Thaum kawg, lub teeb liab dhau los ntawm 100K (R8) lub lauj kaub ntim, rov qab los ntawm qhov hloov pauv thiab mus rau lub qhov tso tawm.
