Nov yog ob qho txuas ntxiv thiab hloov pauv los ntawm ob qhov kev qhia ua ntej. Kuv tau tsim lub cev tseem ceeb ntawm lub thawv thiab ua haujlwm tau zoo, Kuv ntxiv psu thiab ua haujlwm tau zoo, tab sis tom qab ntawd kuv tau sim muab cov kab hluav taws xob kuv tau tsim rau hauv lub thawv uas seem thiab lawv tsis haum. Qhov tseeb yog tias kuv ua rau lawv haum, tom qab ntawd tsis muaj chav los suav nrog qhov project. Qhov kev txiav txim siab uas kuv tau ua yog kom tshem tag nrho cov hloov pauv thiab cov khoom siv hluav taws xob mus rau hauv lub thawv loj tawm ntawm lub hau, muab ntau chav rau xaim.

Tag nrho kaw rau hauv ib lub thawv uas tuaj yeem txav tau yooj yim los ntawm qhov chaw mus rau lwm qhov lossis tso tseg rau kev khaws cia. Tsis pom ntawm no, tab sis sab xub ntiag ntawm lub hau muaj lwm lub rooj sib cais uas cov ntawv sib txuas tau txuas thiab tuaj yeem kho nrog velcro. Kuv mam li npaj cov duab ntawm no asap.

Lub hwj chim tseem ceeb tau tsim rau hauv qab ib nrab ntawm lub thawv thiab tau tsim los ntawm kev lag luam tawm ntawm lub txee hloov chaw, txuas nrog ua ke ntawm cov hloov hluav taws xob thiab muab lub zog rau cov khoom siv hluav taws xob hauv lub hau ntawm lub thawv ntawm 40pin ribbon cable thiab txuas. Lub zog tau muab los ntawm ob lub qhov hluav taws xob nkag thiab 12V dc hloov pauv psu, lossis ntawm XLR lub qhov hluav taws xob npaj kom tau txais lub zog los ntawm 12V roj teeb, yog tias siv hauv RV tab sis tuaj yeem yog lub roj teeb nqa hauv lub thawv nws tus kheej. Lub zog los ntawm ib qho ntawm cov no raug xaiv los ntawm peb txoj kev hloov pauv, lub hauv paus, roj teeb lossis chaw tawm ntawm txoj haujlwm.

Lub zog tau hloov los ntawm lub teeb pom kev zoo rocker hloov los qhia lub zog rau. Lub zog tseem ceeb ntawm kev muab lub zog rau lwm qhov hloov pauv thiab rau 12V pob-txhawb kev muab lub zog rau lub hau hluav taws xob. Qhov no tseem pub rau lub tshuab hluav taws xob tsis zoo yooj yim rau cov khoom sib piv hauv cov zaub.

Ib qho 5V buck-boost module tau muab los ntawm lub teeb pom kev zoo rocker hloov thiab muab 5V rau kev siv los ntawm kev tsim hluav taws xob hauv lub hau thiab tau hla ntawm txoj hlua kab.

A +/- 12V pob-txhawb tus qauv tau muab los ntawm lub teeb pom kev zoo rocker hloov thiab muab ob qho tib si +12V thiab -12V cov khoom siv rau kev siv los ntawm cov kab hluav taws xob sib piv thiab tau hla ntawm txoj hlua kab.

Qhov thib plaub phaw-txhawb tus lej tau pub los ntawm qhov hloov pauv kawg los muab lub zog rau USB hub. Lub USB 2.0 lub hub yog tus nqi qis uas muab plaub lub hwj chim hloov pauv nrog rau cov laj thawj los ua lub hauv paus. Ntau ntxiv txog qhov no tom qab.

Txhawm rau kom haum cov txheej txheem hluav taws xob tshiab, cov vaj huam sib luag tshiab xav tau txiav, txheej txheej ntawm cov no yog hauv pdfs, ntxiv rau txuas ntxiv mus rau sab ntawm lub hau kom muab ntau qhov chaw rau cov xov hlau tom qab.

Lub zog hluav taws xob hauv qhov qub yog los ntawm txiv tsawb ntsaws thiab qhov ntsaws, tab sis nrog qhov no muaj ntau yam khoom siv hluav taws xob, kev sib txuas ntawm lub hau thiab lub hauv paus yog dhau ntawm 40 txoj kab hlua kab. Lub qhov (socket) tau muab muag rau ib daim ntawm pawg thawj coj saib uas raug thawb los ntawm lub qhov ua rau nws thiab ntswj rau hauv qhov chaw. Cov qhov (socket) yog qhov tseem ceeb yog li thaum haum lawv rau cov laug cam lawv yuav tsum tau ua kab kom ntseeg tau tias txoj hlua hlua siv tau haum zoo ntawm lawv thiab tsis thim rov qab. Kuv tau siv 20cm ribbon cable uas ntawm kev ntsuas siv tsuas yog quav zoo li lub hau kaw.

Txhawm rau tsim PSU cov kab hluav taws xob, lawv tau sib sau ua ke ntawm lub vaj huam sib luag thiab muab ntsia rau hauv qhov chaw, nrog rau cov kis los yog pcb kaw. Ob qho tib si tau luam tawm ntawm lub tshuab luam ntawv 3D hauv qhov no tab sis qhov ntawd tsis tsim nyog, tsuas yog tias cov laug cam tau nyab xeeb. Kuv tau ntxiv cov ntaub ntawv.stl yog tias leej twg xav ua kom sai.

Txhua txoj hlua hluav taws xob ntawm lub vaj huam sib luag tau muab muag, tshwj tsis yog kev sib txuas mus rau lub hauv paus PSU kev sib txuas kom pab tau lub hau kom tshem tau yooj yim thiab hloov pauv.

Cov ntsuas hluav taws xob tiv thaiv thiab cov ntsuas hluav taws xob ntsuas hluav taws xob siv cov khoom siv tsis zoo uas xav tau ob qho khoom siv zoo thiab tsis zoo. Qhov khoom siv tau zoo yog tau los ntawm kev nce/nqis phaus hloov pauv uas muab qhov ruaj khov +12V nws tus kheej ntawm cov khoom siv sab nraud. Qhov no pub cov kab hluav taws xob npog thiab cov tshuab hluav taws xob tsis zoo. Keeb xeeb qhov no tau suav nrog hauv tib lub rooj sib txig sib luag li lwm cov khoom siv hluav taws xob tab sis tau raug txiav tawm kom muab tso rau hauv lub hauv paus. Lub Circuit Court rau qhov no tau qhia thiab yog ib txwm muaj 555 timer Circuit rau lub hom phiaj no. Nws tsuas yog muab cov khoom siv tam sim no txaus los ua kom lub suab tsis zoo thiab tsis xav tau rau lwm yam.

Thawj qhov khoom siv USB yog ib khub ntawm lub qhov (socket) hauv lub hau pub los ntawm qhov sib cais 5V thiab muab lub zog nkaus xwb. Vim tias kuv xav kom qhov no txav tau yooj yim li sai tau, Kuv txiav txim siab muab lub USB hub tso rau hauv kev tsim, tsau rau hauv lub hauv paus, thiab nrog hloov kho lub zog pub los ntawm 5V hloov pauv. Lub hub no tseem tuaj yeem siv nrog lub khoos phis tawj ua lub USB hub ua kom yooj yim sib txuas.

Lub hauv paus ntawm USB lub hauv paus tau txais txiaj ntsig zoo thiab cov kev sib txuas uas pom tau muab tso rau ntawm lub rooj tsavxwm. Cov hlau lead tau hloov pauv los ntawm USB hom B lub qhov (socket) nrog tsuas yog lub teeb liab thiab 0V txuas txuas mus rau USB hub Circuit board. Tsis muaj ib txoj hauv kev raug txiav hauv qhov kev hloov kho no, tsuas yog 5V cov khoom siv tau txhim kho los ntawm cov xaim tuab mus rau USB lub zog hloov pauv hauv lub hub thiab xaim txuas ntxiv siv lub zog ncaj qha rau cov pins ntawm lub qhov (socket), hla dhau cov kab hluav taws xob.

Qhov no txhais tau tias cov khoom siv tam sim no txwv rau 3A hloov pauv li ib txwm 500mA, tab sis yuav ua kom muaj zog Raspberry Pi.

Txhawm rau kom haum rau sab saum toj ntawm PSU vaj huam sib luag, lub hauv paus ntawm lub hauv paus tau ntsia hlau nrog lub qhov tso rau cov xov hlau kom hla mus thiab lub hub tau rov ua dua tshiab.

Lub vaj huam sib luag PSU ua tiav tau qhia hauv daim duab.

Cov khoom siv hluav taws xob thiab cov cai Arduino tau them rau hauv ntu kawg tab sis rau kev tsim kho lub tsev yog ib nrab tau qhia ntawm no los qhia qhov twg yuav mus. Lawv tuaj yeem tsim kho sib cais thiab tsis siv nyob rau hauv ib qhov project zoo li no.

Lub zog rau lub vaj huam sib luag zaub tau txuas nrog ntawm 40 txoj hauv kev header lub qhov (socket) uas tau ua kab nrog lub qhov (socket) hauv lub hauv paus kom ntseeg tau tias txoj hlua hlua khi tau zoo.

Hauv qab nws yog khawm rov pib dua rau Arduino, nws yog qhov yooj yim ntxiv thiab raws li tag nrho cov kev cia siab tias yuav yog txoj haujlwm txuas mus ntxiv tuaj yeem xav tau ib ntus.

Hauv nruab nrab yog cov khoom siv hluav taws xob, los ntawm sab saum toj uas yog +12V, -12V, +5V thiab 0V

Hauv qab cov zaub yog ntau yam kev nkag mus rau hauv cov kab hluav taws xob, cov tswv yim digital, cov tswv yim hluav taws xob, tam sim no, txuas thiab I2C pins

Saum toj no cov zaub yog lub caij nplooj ntoo hlav txuas rau qhov ntsuas tsis kam.

Cov zaub muaj qhov yooj yim bezel muab tso rau ib puag ncig nws, tam sim no dawb tab sis yuav hloov pauv yog tias kuv muaj cov yas los ua ib qho.

Kuj pom nyob hauv cov duab yog ob daim ntoo ntoo thiab ib daim yov muab tso rau ntawm lub hau. Tag nrho ntawm lub vaj huam sib luag yuav tsum tau txav mus rau tom ntej kom haum rau cov hlua tom qab. Cov lus qhia txiav rau cov no yog hauv PDFs txuas.

Kauj Ruam 6: Stl Cov Ntaub Ntawv rau Mounts thiab Bezels

Nov yog cov ntaub ntawv stl rau txhua tus neeg uas xav ua, lossis tau ua, ntau yam sawv-tawm, PCB mounts thiab bezel.
