Lub hom phiaj ntawm cov lus qhia no yog los qhia seb koj tuaj yeem ua DUAL DECAY Circuit rau koj li modular synthesizer li cas. Qhov no yog qhov taw tes-rau-taw tes Circuit Court dawb ntawm ib qho pcb thiab qhia tau lwm txoj hauv kev los tsim kev ua haujlwm sib txuas hluav taws xob sib txuas nrog qhov tsawg kawg nkaus thiab tus nqi qis. Nws kuj tseem tuaj yeem yog txoj hauv kev lom zem kom paub ntau ntxiv txog kev siv hluav taws xob thiab nws ua haujlwm li cas.
Kuv tsis siv credit rau qhov kev tsim hluav taws xob no. Nws yog qhov tseeb 1/2 ntawm BMC043 4x Kev lwj. Koj tuaj yeem kawm paub ntau ntxiv txog qhov tsim thawj thiab nws ua dab tsi ntawm no. Barton Musical Circuits yog cov peev txheej zoo rau kev kawm paub ntau ntxiv txog cov qauv tsim hluav taws xob vim tias txhua qhov haujlwm muaj cov lej uas muaj cov lus piav qhia txog yam tshwm sim hauv lub voj voog.
Kuv coj ib nrab ntawm qhov kev sib tw no los ua 2 chav sib cais los ntawm ib qho TL074 hauv qhov taw tes-rau-taw qhia version. Cov nqi them tsawg dua $ 5.00 rau qhov kawg uas kuv tau ua nrog lub tshuab txiav laser.
Kuv sau cov ntawv qhia no ua ib daim ntawv rau kuv tus kheej txoj kev kawm thiab txoj haujlwm no xav kom koj muaj qee qhov kev nkag siab ntawm cov khoom siv hluav taws xob thiab yuav siv cov hlau txuas li cas. Tsuas muaj ib tus neeg uas kuv paub tam sim no ua hom kev tsim kho cov qauv siv hluav taws xob. Koj tuaj yeem pom nws cov lus qhia ntawm no.
Yog tias koj yog game txaus los tso qhov no ua ke, qhia rau kuv paub tias nws tshwm sim li cas. Khiav mus rau ib qho teeb meem, pom qhov ua yuam kev, qee yam kuv tau sau tsis muaj kev nkag siab txhua? Ntaus kuv kom kuv tuaj yeem tshuaj xyuas thiab kho kom txhim kho cov lus qhia.

Txoj haujlwm no tuaj yeem hloov kho kom haum rau koj cov kev xav tau thiab hom synth.
Zoo rau ob lub voj voos thiab plaub fab.
Kauj Ruam 2: Tus Potentiometers
INFO: Koj cov cim taw qhia tuaj yeem yog lub qhov rooj qhib, lfo, lub hauv paus suab, txhua yam uas koj pub rau nws thiab tsuav yog nws muab tawm tsawg kawg 1v, kev lwj yuav koom nrog.
Txog qhov kev tsim no, peb tus lej nkag ntawm TL074 yog tus pin 3 thiab 12.
- Cap cov tswv yim no los ntawm kev tso lub. 01uF (100nF / 104) ceramic capacitor ntawm tus pin 3 thiab lwm.01uF cap ntawm tus pin 12. Saib cov duab 1, 2, 3, 4. Lwm qhov xaus tuaj yeem dai dawb rau tam sim no. Cov ntsiab lus ntawd yuav txuas rau koj cov tswv yim jacks tom qab.
- Tom ntej twist 2 100k resistors khi lawv ob txhais ceg ua ke. Ob txhais ceg sib tw txuas rau hauv av. Lwm qhov xaus ntawm 100k resistors yuav txuas rau tus pin 3 thiab 12. Cov laug nyob hauv qhov chaw thiab txiav tawm qhov ua dhau. Saib cov duab 5,6 rau kev siv.
NCO TSEG:.01uF 100nF yog ob txoj hauv kev sib txawv los siv tib tus nqi capacitor thiab cov disc ceramic feem ntau yog cim nrog tus lej lej kom yooj yim txheeb xyuas. Tus lej capacitor rau 100nF yog 104.
Kauj Ruam 7: Tam sim no txwv cov tiv thaiv rau LEDs
Tom ntej no peb yuav ntxiv 1k tam sim no txwv kev tiv thaiv uas yuav tiv thaiv LEDs ntawm txhua lub channel.
- Txuas 1k resistor rau tus pin 6 thiab 7 thiab lwm 1k resistor rau tus pin 8 thiab 9 ntawm sab nraud. Lwm qhov kawg ntawm cov neeg tawm tsam tuaj yeem dai ib pliag.
NCO TSEG: Cov ceg tiv thaiv kab rov tav tuaj yeem tsau rau tam sim no. Lawv yuav txuas nrog anodes ntawm LEDs sai sai no.
Kauj Ruam 8: Ua kom tiav av
Peb tau ze heev, tab sis ua ntej peb mus ntxiv peb ua kom tiav cov kev sib txuas hauv av rau lub zog thiab lub zog. Nrog cov seem hlau, cov kab sib txuas ntawm cov pins koom nrog 2 thiab 3 rau txhua lub hwj chim thiab khiav cov xaim mus rau qhov chaw hauv nruab nrab taw tes rau lub tsho thiab LEDs.
Kauj Ruam 9: Kab Kab Koom Nrog Vaj Huam Sib Luag
Cia peb pib nyab xeeb TL074 rau lub vaj huam sib luag tam sim no. Taw qhia cov nti saum toj no channel 2 potentiometer yog li hauv av "tail" hovers saum lub qhov (socket). Kev koom ua ke los ntawm cov khoom siv hluav taws xob txuas hluav taws xob txuas rau txhua lub hwj chim tuaj yeem txuas nrog tom ntej. Lub lauj kaub saum toj yog channel 1 thiab lub lauj kaub hauv qab yog channel 2.
Lub diode ntawm channel 2 lauj kaub txuas rau tus pin 14. Cov ceg sib tw los ntawm channel 2 lauj kaub mus rau tus pin 10 raws li qhia hauv (daim duab 1). Muab cov hlua sib tw coj los ntawm lub lauj kaub 2 mus rau lub diode txuas ntawm tus pin 14 vim tias cov no yog nyob ze ze lawm.
Txij li cov channel 1 lauj kaub nyob deb dua, Kuv yuav siv cov xaim kom ua tiav cov kev sib txuas raws li tau hais hauv (daim duab 2). Cov ceg sib tw los ntawm channel 1 lauj kaub mus rau tus pin 5. Lub diode ntawm channel 1 lauj kaub txuas rau tus pin 1.
Ua kom tiav qhov kev sib txuas hauv av los ntawm tus Tsov tus tw ntawm cov kab tuag mus rau lub hauv paus hauv paus ntawm lub tsho thiab LEDs zoo li koj tuaj yeem pom hauv (daim duab 3).
Kauj Ruam 10: Txuas cov LEDs
Cov ceg uas tsis zoo ntawm qhov txwv tam sim no 1k resistors tam sim no tuaj yeem txuas nrog LEDs.
1k resistor los ntawm tus pin 6 thiab 7 ntawm TL074 mus rau qhov anode ntawm LED rau channel 1. Saib (daim duab 1).
1k resistor los ntawm tus pin 8 thiab 9 ntawm TL074 mus rau qhov anode ntawm LED rau channel 2 thiab txij li nws nyob deb dua kuv tau siv ib daim xaim xaim. Saib "ib nrab" hauv (daim duab 2).
Kauj Ruam 11: Qhov Tso Tawm Voltage Divider
Pair li 2.7k nrog 2.2k resistor thiab ntswj ib sab ntawm lawv ob txhais ceg ua ke. Ua qhov no rau txhua khub.
Channel 1. Ob txhais ceg ntawm 2.7k resistor yuav txuas ncaj qha rau tus pin 7 rau channel 1 tso tawm thiab ceg ntawm 2.2k resistor mus rau hauv av tsheb nqaj hlau "tus Tsov tus tw". Cov ceg sib tw ntawm ob qho tib si yuav txuas rau qhov ntxeev ntawm channel 1 tso tawm jack.
Channel 2. Ob txhais ceg ntawm 2.7k resistor yuav txuas ncaj qha rau tus pin 8 rau channel 2 tso tawm thiab ceg ntawm 2.2k resistor mus rau hauv av tsheb nqaj hlau "tus Tsov tus tw". Cov ceg sib tw ntawm ob qho tib si yuav txuas rau qhov ntxeev ntawm channel 2 tso tawm jack. Thov txim rau qhov muag plooj, ntu no tau qhia hauv (daim duab 2) nrog cov xaim ntsuab mus los ntawm ob txhais ceg ntswj mus rau qhov tso tawm.
NCO TSEG: Ntawm qhov no ib zaug ntab ntab TL074 yuav tsum tam sim no xav tias muaj kev nyab xeeb nyob hauv qhov chaw. ** Kuv yuav sim qhov kev qhia no los ntawm kev tsim nws thiab xyuas kom tau txais cov duab zoo ntawm cov no los suav nrog hauv cov kauj ruam no.
Kauj Ruam 12: Hwj chim thiab Ua Si
Yog li, qhov kev sib tw no tau ua tiav thaum koj ua lub zog. Ib feem no nyob ntawm koj daim ntawv thov tshwj xeeb. Kuv tsim hauv Eurorack hom ntawv thiab siv cov taub hau npog thiab cov hlua txuas txuas rau lub rooj faib hluav taws xob uas tau txais lub zog los ntawm AC hloov pauv lub zog siv. Txhua tus neeg tuaj yeem ua qhov no sib txawv me ntsis tab sis dab tsi tseem zoo ib yam rau kev ua haujlwm hauv lub zog yog txhawb lub zog zoo thiab tsis zoo nrog +/- 12v thiab txuas hauv av.
Koj kuj tseem yuav xav ntxiv tus nqi qis tus tiv thaiv (10r) los ntawm lub zog siv rau txoj kab zoo thiab tsis zoo thiab qee lub tshuab hluav taws xob txhawm rau lim lub suab nrov los ntawm cov ntsia hluav taws xob.
Rau txoj kev tsheb nqaj hlau zoo +12v, siv 10uF electrolytic capacitor. Qhov anode ntawm lub hau mus rau txoj kev tsheb nqaj hlau zoo thiab cathode mus rau hauv av. Tsis tas li, tso ib.01 (100nf / 104) ua ntu zus los ntawm txoj kev tsheb nqaj hlau mus rau hauv av.
Rau qhov tsis zoo -12v, siv 10uF electrolytic capacitor. Lub cathode ntawm lub hau mus rau txoj kev tsis zoo thiab cov anode mus rau hauv av. Tsis tas li ntawd, tso ib.01 (100nf / 104) ua ntu zus los ntawm txoj kev tsheb ciav hlau tsis zoo mus rau hauv av.
Qhov no tau qhia hauv cov txheej txheem tseem ceeb rau lub zog.
ZOO TSHAJ PLAWS:
- Kuv tau suav cov duab los ntawm 2 qhov sib txawv ntawm qhov kev sib tw no los qhia qhov ua haujlwm zaum kawg. Daim ntawv ceeb toom lawv txhua tus tau hloov me ntsis sib txawv raws li kuv tau hloov kho kom nruj qhov tsim thiab pom txoj hauv kev zoo dua los tso cov khoom. Yog li thov nco ntsoov, yog tias koj tsis tau txais nws los ua haujlwm thawj zaug, tsuas yog sim ua. Nws yeej tsis raug nqi ntau npaum li qhov ua tsis tau ob peb zaug. Koj yuav tau txais nws thaum kawg thiab koj yuav pom txoj hauv kev zoo dua txhua lub sijhawm.
- Ib qho module no zoo nkauj tsis muaj txiaj ntsig ntawm nws tus kheej. Kuv npaj yuav ua ntau yam ntawm Cov Lus Qhia rau lwm hom kev hloov pauv yog li qhov no tuaj yeem muaj phooj ywg thiab lawv txhua tus tuaj yeem ua si ua ke. Lub sijhawm no, tsuas muaj ib tus neeg uas kuv paub ua tus taw qhia-rau-taw qhia Qhia rau cov qauv sib txuas. Modular rau pawg (M4TM). Juanito zoo nkauj heev thiab muaj lub luag haujlwm ua rau kuv xav paub hauv P2P lub tsev tsim hluav taws xob. Yog li txheeb xyuas nws nplooj ntawv uas muaj ntau qhov txias tshaj Qhia rau tsim P2P modular synth modules. Cov haujlwm no yuav ua ke zoo nrog qhov no. Juanito's nplooj ntawv nyob ntawm no.
