Qee qhov nws coj ib lub block nrog ib qho hluav taws xob ruaj ruaj nyob rau hauv ntau cov khoom siv. Nws yog qhov nyuaj ua qhov no nrog kev hloov kho kom haum, thiab txawm kom muab kev sib hloov ntawm lub potentiometer lis txhua lub sijhawm qhov tsim nyog voltage tsis yog yooj yim. Tom qab ntawd kuv txiav txim siab los ua qhov yooj yim nrog peb tso tawm voltages 5v, 9B, thiab 12v ntawm cov nti sib xyaw-stabilizers.

Kev Siv Hluav Taws Xob Rau 3 Hluav Taws Xob
Lub hauv paus tau npaj tau ua rau muaj 12 v. Yog tias koj xav tau txais 5 lossis 9, lub tes hloov tawm cov zis los ntawm cov chips sib tov. Leds tsom rau cov voltage.
Cov ntaub ntawv ntau lawm rau kev thaiv
Lub thaiv lub cev yog ua los ntawm cov kav dej phwj. Yuav ua li cas qhov no tau piav qhia nyob rau hauv kev nthuav dav ntawm no -
PVC Yas yog txiav rau hauv kev sau qoob loo ntawm rooj plaub:
Tom qab ntawd, nrog kev pab ntawm lub superconcepcepcepcepception, ob sab tau lo rau ib leeg.
Lub tsev nyob yog drilled los ntawm opupings rau cov xa tawm thiab cov xov hlau tawm, coj, hloov.
Pob ntseg yog glued nyob rau hauv cov ces kaum kom nws txias rau lub hau.
Lub hau kos yog ntaus ntawv nrog cov kab xev thiab tho cov qhov ntawm cov fab, tho qhov hau thiab pob ntseg nws tus kheej.
Thov Vajtswv cov khoom ntawm ib sab.
Sib dhos cov fais fab yooj yim rau 3 volfages
Mus rau cov kev sib txoos ntawm lub block. Peb hla cov xov xwm network thiab kho cov nylon screed.
Peb disassemble lub block nrog lub voltage ruaj khov thiab nqa lub rooj tsavxwm.
Cov thawj coj yog ntxig rau hauv lub tsev tshiab ntawm ob tog sedded adhesion. Kuj zoo qhov chaw rau cov chips.
Rau peb coj peb solder tiv thiab insulating lub tshav kub ntsws.
Ntxig cov leds rau hauv vaj tse thiab hloov.
Txog kev ntseeg tau, txhua yam tuaj yeem pouring kub kua nplaum. Kev xa tawm ntawm cov coj raws li cov txheej txheem.
Peb ham hlau thiab diodes rau microchliuits.
Microcircuits raug teeb tsa rau cov radiators, ntsia hlau mus rau lub xaib. Tawm cov solder li hauv cov phiaj xwm.
Peb kaw lub nraub qaum thiab kho cov screws.
Lub hauv paus yog npaj los siv.
Qhov tseeb uas chips yog muab zais rau sab hauv tsis ntshai. Txhua yam nti no muaj kev tiv thaiv tam sim no thiab ntsuas kub. Nrog tshaj 70 degrees Celsius, nws yuav muab tua nws txias.
