Video: Roj teeb mus rau DC Tsav Hloov Chaw, Teeb Pom Kev Zoo (lossis Zoo Li Txhua Yam): 5 Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27
Qhov no tej zaum yog txoj hauv kev yooj yim tshaj plaws los hloov lub nrawm los ntawm roj teeb mus rau DC lub zog xa hluav taws xob.
Qhov Yongnuo YN560IV no xav tau qee zaum hauv peb lub rooj muag khoom duab, kom pom lub phab ntsa tom qab thiab tshem tawm qhov ntxoov ntxoo los ntawm qhov kev kawm.
Muaj ntau cov ntaub ntawv kom pom nyob hauv cov rooj sib tham txog qhov kev hloov pauv no, thiab tsuas yog ob peb daim diy yeeb yaj kiab. Kuv xav qhia kuv cov kev paub nrog txoj haujlwm no vim tias muaj qee qhov teeb meem uas tsis muaj leej twg tau hais lossis piav qhia ntau npaum li kuv tau pom.
Muaj kev tshaj lij ua cov roj teeb dummy rau dc lub zog hloov khoom siv hloov pauv uas tau muag. Koj tuaj yeem pom lawv online yog tias koj tsis xav tinker nrog cov xov hlau thiab cov laug.
Kauj ruam 1: Converter
Kuv xaiv tus 6V 2A AC/DC hloov pauv. Lawv tau yooj yim kis los ntawm eBay. Qhov no raug nqi kuv tsawg dua 10 Euro. Lub 5V hloov pauv tej zaum yuav ua haujlwm ib yam nkaus.
Koj xaiv tus hloov pauv raws li daim ntawv thov. Tus speedlite yuav muaj sijhawm luv lossis luv luv nyob ntawm Amperage. Kuv xam tias 2A yuav txaus rau kuv, tab sis txog li 4A lub peev xwm tuaj yeem tsim nyog dua nyob ntawm koj xav tau.
Tus hloov pauv tuaj nrog 5, 5/2, 1mm tus qauv DC txiv neej ntsaws, tseem hu ua LED txuas. Kuv tau yav dhau los yuav poj niam thiab txiv neej txuas nrog cov ntsia hlau clamps rau xov rau lwm txoj haujlwm. Cov no tseem muaj nyob hauv eBay.
Qhov txuas yog ntawm kev xaiv raws li koj tuaj yeem hle thiab muab cov hlua txuas ua ke tas li, lossis siv lwm qhov txuas uas tsim nyog. Tsuas yog taug qab koj + thiab -
Kauj Ruam 2: Mus Los Ntawm Qhov Chaw Roj Teeb
Txoj hauv kev no koj tau txais kev kho kom huv thiab huv si yam tsis tas yuav qhib sab hauv ntawm koj lub cuab yeej thiab cuam tshuam nrog cov khoom siv hluav taws xob. Feem ntau qhov kev hloov kho me me rau lub hau lossis lub tsev yuav tso cai rau xaim tawm kom pom zoo..
Qhov kev nrawm no khiav tawm ntawm 4 AA hlwb uas txuas nrog ua ke kom tsim tau txog 5-6V tag nrho.
Tam sim no koj tuaj yeem npaj qhov no hauv ob txoj hauv kev:
1. Tog twg los tsim 3 dummies uas tsuas yog luv luv ob qho ua ke, thiab 1 dummy uas txuas nrog rau + thiab - ntawm cov khoom siv hluav taws xob (cov kev daws teeb meem feem ntau zoo li no).
2. Tsim tsuas yog 2 dummies, ib qho rau + thiab ib qho rau -… tab sis koj yuav tsum txiav txim siab thiab qee qhov nco qab uas nkag mus rau lub qhov (socket). Kuv tau xaiv qhov kev daws teeb meem no vim nws zoo li yooj yim kom haum cov xov hlau hauv chav. Cov dummy dub (xaim xiav) txuas nrog "-" thiab cov nyiaj dummy tau txuas nrog "+"
Siv koj lub tswv yim thiab txhua yam koj muaj ntawm tes. Kuv siv daim ntoo ib puag ncig thiab daim xaum, thiab qee daim kab xev eletrical thiab kab xev. Cov ntsia hlau ua haujlwm li tus ncej txuas. Cov xov hlau tau raug mob ib puag ncig cov ntsia hlau thiab zais hauv qab cov kab xev nyob ib ncig ntawm tus neeg dag.
Kauj Ruam 3: Tam Sim No Txwv Tiv Thaiv
Nov yog qhov tseem ceeb ntawm txoj haujlwm no.
Vim tias kuv muaj lub zog 2A, nws tsis ua haujlwm! Kuv txuas lub hwj huam hluav taws xob rau sab xis ntawm lub roj teeb, tab sis Speedlite tsis qhib. Tab sis muaj lub suab nyem nyem thaum kuv tuav lub hwj chim khawm rau.
Nws hloov tawm tias thaum Speedlite tau qhib, nws sim kos ntau dua 2Amps. Thiab thaum nws ua, tus hloov pauv nkag mus rau "hom hiccup". Nws tig rau thiab tawm thiab tawm thiab tawm… txhawm rau tiv thaiv nws tus kheej los ntawm kev dhau mus.
Los ntawm kev tso tus tiv thaiv tam sim no txwv rau + ntawm tus hloov pauv thiab lub nrawm nrawm, nws muaj peev xwm ua rau lub nrawm nrawm pib txawm tias tsuas yog 2Amps, tab sis nws yuav siv ob peb feeb ntev dua.
Siv Ohms txoj cai los xam seb koj xav tau kev tiv thaiv ntau npaum li cas. Tus hloov pauv tuaj yeem muab ntau tshaj 2Amps, thiab nws tsav 6Volts.
6/2 = 3 AWM
Kuv tsis muaj 3 Ohm resistor yog li kuv yuav tsum tsim kuv tus kheej xaim qhov txhab tiv thaiv. Txhawm rau ua li ntawd kuv siv ob txoj hlua ntawm cov hlau hlau tsim, ntev txog 30cm. Cov hlua hlau hlau no tau raug mob nyob ib puag ncig ntawm tus cwj mem xaum ntawm lub roj teeb dummy hauv peb txheej, sib cais los ntawm kab xev hluav taws xob thiab lub raj nqaim.
Nco tseg! NiChrome hlau feem ntau yog siv los tsim lub zog tiv taus. Txawm li cas los xij cov khoom siv hlau no (tej zaum yog som chrome-hlau alloy), ua haujlwm tau zoo heev thiab, thiab tej zaum yuav yooj yim dua tau (thiab yuav pheej yig dua?). Koj tuaj yeem sim nrog txhua yam hlau hlau uas koj muaj hauv tsev. Qhov thinner nws yog qhov ua haujlwm ntau dua nws ua.
Ceeb toom! Ib txoj hlua hlau nyias tau dhau los ua kub heev hauv qhov hnyav, kub dhau los kov. Li no los ntawm kev siv ob txoj hlua ntev dua qhov kev tiv thaiv tau khaws cia zoo ib yam tab sis tsis muaj qhov teeb meem overheating.
Tswv yim! Txhim kho cov hlua hlau hlau kom ua rau nws muaj pliabel ntau dua thiab yooj yim rau ua haujlwm nrog. Anneal nws siv tsuas yog lub teeb nrig lossis tswm ciab.
Kuv zais cov xaim tiv thaiv sab hauv cov roj teeb dummy. Nws tsuas yog ntsuas 2 Ohms ntawm kev tawm tsam, thiab tsis yog tag nrho 3 ohms uas tau suav. Tus speedlite tseem tig rau, hiccupy me ntsis thaum xub thawj, tab sis tom qab ntawd nws tau ua haujlwm du.
Kauj Ruam 4: Qhov Ua Kom Zoo Nkauj?
Koj xav li cas? Kinda zoo li kev koom ua ke.
Kauj Ruam 5: Cov ntsiab lus, Cov ntsiab lus tseem ceeb
Siv cov roj teeb dummy los muab lub zog rau lub nrawm lossis lwm yam khoom siv. Kuv lub koob yees duab digital tseem siv 4 lub roj teeb thiab nws ua haujlwm rau cov dummies no ib yam.
Nco ntsoov xaiv lub hwj huam txaus. Nrog 2Amps lub sijhawm hloov pauv rau kuv qhov nrawm tom qab tawg 1/1 yog 9 vib nas this. Kuv tsuas yog siv cov speelite rau 1/32 lossis 1/64 yog li rau kuv uas tsis muaj teeb meem.
Nco ntsoov tias speedlites tsis muaj cua sov sib txawv zoo, yog li tsis txhob cia siab tias nws yuav ua haujlwm txuas ntxiv thaum nruab hnub thaij duab tsuas yog vim nws txuas nrog lub hauv paus. Speedlites tuaj yeem ua kom sov!.
Nws yog ib qho tseem ceeb uas yuav tsum tau siv lub zog tiv thaiv tam sim no yog tias lub cuab yeej tuaj yeem kos ib amperage ntau dua li qhov hloov pauv tau ntsuas rau. Kuv tus hloov pauv tau muaj kev tiv thaiv tam sim no, hmoov zoo rau kuv, txwv tsis pub kuv xav tias tej zaum yuav hlawv nws thawj zaug.
