Eurorack Synthesizer Power Supply yog dab tsi?

Ua ntej dab tsi yog Eurorack Synthesizer? Eurorack yog ib hom kev hloov kho uas siv los tsim tus kheej Synthesizer. Hauv cov kab ke no suab ua ke tau ua tiav los ntawm kev sib txuas sib txuas ntawm cov cim sib txawv ntawm cov qauv sib txawv. Eurorack tau tshaj tawm thawj zaug los ntawm German hom Doepfer, tam sim no nws tau nthuav tawm tag nrho lwm cov txheej txheem sib xyaw ua ke.

Qhov "patching" (aka thaiv) ntawm cov qauv tso cai rau kev hais lus nyuaj heev, suab hloov pauv thiab ua ntu zus.

Hom kev sib txuas ua ke no tau siv dav hauv cov suab paj nruag ib puag ncig (Mloog Tus Neeg Tsis Txaus Siab Lub Suab Nkauj), hauv suab paj nruag hluav taws xob thiab tsim hluav taws xob (Mloog Colin Benders).

Yuav ua li cas txog lub hwj huam mov?

Hauv Eurorack system lub suab thiab kev hloov kho tau ua tiav ntawm lub vaj huam sib luag pem hauv ntej ntawm chav tsev siv mono lossis tso suab 3.5mm jacks. Txhawm rau ua kom tus neeg siv cuam tshuam los ntawm kev sib tsoo dhau los txhua qhov kev xa hluav taws xob tau ua tiav los ntawm kev txuas tom qab ntawm tus qauv.

Feem ntau lub zog xa los ntawm lub tsheb npav uas muab txhua tus qauv ua ke nrog -12/+12 V, 5V thiab hauv av. Lub tsheb npav tseem tswj hwm cov cim tseem hu ua CV (tswj qhov hluav taws xob) tab sis cov teeb liab no tsis tshua muaj siv. Qhov Eurorack cov qauv tau dav raws li cov khoom siv hluav taws xob sib xws yog li -12/+12 V qhov hluav taws xob. Tab sis raws li cov txheej txheem DSP niaj hnub tau txais ntau thiab nrov dua (Saib Cov Khoom Siv Hloov pauv) qhov xav tau rau qhov zoo 5V kev tsheb nqaj hlau yog qhov tseem ceeb heev.

Vim li cas thiaj ua lub hwj chim DIY?

DIY zej zog ib puag ncig Eurorack Synth yog qhov loj heev. Uas ua rau cov peev txheej tsim muaj rau txhua tus neeg xav nrhiav lawv.

Ua ntej kuv yog tus ua tiav tshiab rau hauv synth modular thiab kuv xav kawm paub ntau ntxiv txog nws. Kuv xam pom tsim ib qho ntawm kuv tus neeg tsim khoom siv kuv tus kheej yuav qhia kuv ntau dua li rub tawm cov vis dis aus Youtube rau lub hnub nyoog tab sis kuv tseem tsis tau npaj los coj kuv txoj hauv kev ntawm kev tsim lub suab ua qauv tsis tau. Tias yog vim li cas kuv thiaj mus rau ntu "yooj yim": lub hwj chim.

Qhov thib ob kuv xav tau cov ntaub ntawv tshwj xeeb nrog lub hwj chim muab kev koom ua ke zoo hauv nws, yog li ua ob rooj plaub thiab PSU yuav ua kom ntseeg tau tias kuv yuav tau txais qhov txiaj ntsig kuv xav tau (feem ntau yuav tsis zoo li tawm ntawm lub txee daws teeb meem, tab sis kuv tsis quav ntsej) ntau dhau kuv tsis yog kws tshaj lij suab paj nruag li cas los xij). Kuv yuav ua rooj plaub sai li sai tau thaum kuv muaj sijhawm (saib rau yav tom ntej qhia).

Thib peb Kuv muaj daim ntawv tso cai rau Altium tus tsim los ntawm kuv txoj haujlwm thiab kuv tau ua PCBs yav dhau los. Qhov no yuav tsum tsis txhob nyuaj ua kom pawg thawj coj no ua haujlwm.

Plaub thiab thaum kawg, Kuv yog tus txiv neej pheej yig, thiab kuv xav tias vim li cas tsis txuag ib pawg ntawm cov khoom siv hluav taws xob kim. Qhov ntawd tau hais tias kuv xav tias nws yuav xaus mus kim dua qee qhov nrov tshaj plaws Eurorack cov khoom siv hluav taws xob. Tu siab rau kuv.

Kauj ruam 2: Yuav tsum tau ua

Yuav tsum muaj
Yuav tsum muaj

Raws li peb tau pom hauv ntu yav dhau los cov khoom siv hluav taws xob muaj 3 txoj kab hluav taws xob -12/+12V, 5V thiab hauv av (lossis 0V).

Muaj ob lub tswv yim uas nyiam kom ua tiav cov txiaj ntsig zoo ib yam:

  1. lub tshuab hloov pauv raws li tsim nrog lub kais nruab nrab kom tau txais av hauv av, ob qho tib si tau txais kev kho thiab tswj kom tsim tau ob txoj kev tsheb nqaj hlau
  2. DC lub zog tsim khoom tsim uas tom qab ntawd hloov mus rau -12/+12 V nrog kev hloov pauv hom kev tswj hwm

Thawj qhov kev daws teeb meem yog qhov zoo vim txhua yam tau tsim los rau hauv lub zog siv. Nws siv 115/230V AC ua tswv yim. Tab sis koj yuav tsum tau txaus siab ua ib puag ncig nrog lub ntsiab AC, thiab koj yuav xav tau lub zog hloov pauv loj hauv Eurorack rooj plaub. Lossis koj yuav xav tau AC phab ntsa hloov pauv, uas tsis muaj dav siv sai li sai tau thaum koj xav tau lub zog ntau dua ntawm koj lub cev.

Qhov kev daws teeb meem thib ob yog qhov zoo vim nws tuaj yeem siv lub laptop muaj zog zoo li lub zog cib. Tab sis tus hloov pauv kev tswj hwm yuav ua rau muaj suab nrov me ntsis ntau dua li nws cov kab sib piv uas tuaj yeem siv tau hauv kev daws teeb meem dhau los. Tsis tas li OEM fais fab mov cib tuaj yeem kim heev.

Hauv txhua qhov xwm txheej Kuv tsis xav cuam tshuam nrog kev xa cov hloov pauv kom raug lossis kuv tsis xav koom nrog hauv kev sib txuas hluav taws xob hluav taws xob. Yog li cov khoom siv hluav taws xob uas peb yuav ua yuav yog qhov hloov pauv raws li ib qho.

tso tawm ib puag ncig 1A @ -12V, 1A @ +12V thiab 2A @ 5V rau qhov zoo tshaj plaws nyob ib ncig ntawm 34W ntxiv rau qee qhov cua sov (peb yuav zaum txuag hluav taws xob hauv tsev)

  • yuav daisy chainable kom ib lub cib fais fab tuaj yeem siv rau ntau lub zog siv
  • ua tau raws li chav nyob ua ntej lossis teeb tsa sab hauv lub rooj sib hais
  • muaj tus kheej tsim txhua yam ua los ntawm cov laug cam
  • on-off hloov
  • LED qhov ntsuas hluav taws xob qhov xwm txheej
  • tsis tshua muaj suab nrov tawm qhov hluav taws xob yog tias ua tau

Txhawm rau tsim cov phiaj xwm rau lub zog siv hluav taws xob no peb yuav tsum nrhiav kev hloov pauv hom kev tswj hwm muaj peev xwm xa +12V thiab -12V los ntawm ib qho khoom siv. Peb tuaj yeem muaj ob lub IC sib txawv (sib xyaw ua ke) rau qhov zoo thiab tsis zoo tsheb nqaj hlau tab sis muaj tib yam yuav yooj yim rau kev tsim.

Kuv ib txwm tshawb nrhiav cov khoom siv hluav taws xob siv Digikey lossis Mouser. Ob qho tib si muab cov txheej txheem lim dej muaj zog tiag tiag los nrhiav qhov tshwj xeeb.

Kuv xaiv tus tswj hwm rau -12/+12 V yog LM2576S -12 los ntawm TI.

Feem ntau hais lus yog tus tsim khoom IC xav kom koj siv lawv ib feem lawv yuav muaj cov phiaj xwm zoo nrog txhua yam koj xav tau kom tau txais cov phiaj xwm raug. Hauv cov txheej txheem rau cov khoom siv no tau piav qhia txog cov khoom siv hluav taws xob zoo, cov khoom siv tsis zoo thiab txawm tias siv cov lim tawm.

Rau txoj kab tsheb 5V peb yuav mus nrog LM2576-5 los ntawm TI. Qhov no tsis yog qhov kev xaiv pheej yig tshaj plaws tab sis nws txuag lub sijhawm thaum tsim cov phiaj xwm txij li txhua qhov kev mob siab rau zoo ib yam li rau 12V version. Kuj hneev taw yog tib yam uas txuag ib pawg ntawm lub sijhawm.

Muaj 3 xwm txheej LED uas txhua tus txuas nrog rau txoj kev tsheb nqaj hlau txhawm rau txhawm rau tshaj qhia rau tus neeg siv tias txhua yam ua haujlwm lossis tsis yog.

Tsim cov txheej txheem tsis yooj yim, tab sis nws tsis nyuaj ib yam. Nws ib txwm nyob ntawm qhov txwv.

Kuv lub ntsiab lus tiv thaiv lub sijhawm no yog khaws txhua yam hauv lub duab plaub ntawm 100mm txog 60mm. Yog vim li cas rau qhov tshwj xeeb qhov ntev no yog cov hauv qab no:

  • tsawg dua 100mm qhov ntev vim yog PCB kev tsim cov lus hais rau lub ntim qis uas nyiam ntau qhov loj 100mm (dav lossis ntev) tsim, nco ntsoov, Kuv yog tus txiv neej pheej yig: P
  • tsawg dua 60mm dav txij li kuv xav kom tus qauv haum rau hauv "skiff" Eurorack cov ntaub ntawv uas feem ntau muaj qhov txwv qis heev.

Dav uas nyob hauv siab kuv tuaj yeem taug qab tus txheej txheem ntawm kuv PCB, sau nws thiab ua txhua qhov cim tseg.

Daim ntawv ceeb toom tias nws yog pawg thawj coj saib ob tog, muaj 4 txheej yuav ua rau txheej txheem txheej txheem yooj yim dua tab sis yuav raug nqi ntau dua. Txhawm rau kom tseem tau txais cov av zoo Kuv khaws kuv feem ntau ntawm kuv cov cim rau ntawm txheej txheej saum toj kawg nkaus thiab muab cov av pov rau ntawm ob sab. Ob lub ncuav tau xaws nrog ntau lub vias kom ntseeg tau qhov zoo tshaj hauv av, yog li txo qis suab nrov (vam tias).

Nws ib txwm muaj txiaj ntsig kom nco ntsoov qhov hneev taw 3D ntawm koj cov khoom siv txij li thaum cuam tshuam nrog cov khoom siv hluav taws xob cov khoom ntawd feem ntau zoo nkauj heev.

Thaum cov txheej txheem tiav peb cov poom tam sim no tso tawm cov ntaub ntawv gerber thiab xa cov ntawd rau peb cov chaw tsim khoom nyiam. Hauv kuv qhov xwm txheej kuv xa cov ntawv mus rau PCBWay (Kuv tsis koom nrog, tab sis kuv ib txwm muaj hmoov zoo nrog lawv yav dhau los). Cov txheej txheem xaj yog tuag yooj yim.
