Tam sim no peb tau pom cov 12 volt camper txias txias tig los ntawm cov chaw muag khoom muag thiab cov khw muag khoom lag luam (Kuv pom ib qho rau $ 2.50), ntawm no yog lub tswv yim me me kom hloov nws mus rau hauv lub thawv txias me me uas siv tau los ntawm USB chaw nres nkoj!
Kauj Ruam 1: Tshem Tawm Chav Peltier/Heatsink
Koj tsuas yog xav tau lub phillips lub taub hau ntswj taub hau thiab lub qhov ntsawb nyias los yog rab rab rab rab txhawm rau txhawm rau sib cais lub rhaub dej kub thiab kiv cua, uas yuav tso cai rau koj tshem lub tshuab los ntawm lub tshuab txias. Tam sim no, koj yuav nug yog vim li cas koj thiaj xav ua qhov no thiab tsis yog siv lub txias xwb. Cov lus teb yog vim tias feem ntau ntawm lub sijhawm koj pom ib qho ntawm cov ntaub ntawv no yuav tawg thiab txoj hlua ploj, tab sis qhov ntawd tsis yog teeb meem …
Kauj Ruam 2: Chav Peltier thiab Ntxuav
Sandwiched nyob nruab nrab ntawm cov rhaub dej kub, koj yuav pom chav Peltier, uas loks txog qhov loj thiab tuab tib yam li lub computer CPU. Hauv nruab nrab ntawm txheej saum toj thiab hauv qab, koj yuav pom cov txheej txheem tshwj xeeb uas muaj cov yam ntxwv tshwj xeeb uas ua rau Peltier chav txias ntawm ib sab thaum ua kom sov lwm qhov thaum siv hluav taws xob tam sim no. Yuav muaj, qee zaum, yuav tsum tau tsuag tshuaj tsuag ua npuas dej nyob nruab nrab ntawm ob lub rhaub dej kub, uas yooj yim tawg yooj yim nrog koj tus ntiv tes nkaus xwb. Koj tuaj yeem tshem tawm chav peltier kom ruaj ntseg los ntawm lwm lub rhaub dej kub, vim nws yuav tuav los ntawm cov cua sov sib xyaw. Thaum koj tau ntxuav cov cua sov sab saum toj thiab hauv qab, tso lub peltier rov qab nruab nrab ntawm ob lub rhaub dej kub thiab rov txhim kho lub bolts. Yog tias koj muaj cov cua sov tso tseg los ntawm kev tso ua ke koj tus kheej lub PC, koj tuaj yeem xaiv qhov huv los muab cov qub tso tseg thiab rov thov dua tshiab rau txhua qhov heatsink ib yam li koj xav tau ntawm CPU heatsink/kiv cua sib dhos ua ntej txuas rau CPU.
Kauj ruam 3: Txuas tus USB Cable
Peltier units tau tsim los ua haujlwm ntawm qhov hluav taws xob ntawm 3-12 volts, thiab 5 volts los ntawm koj lub chaw nres nkoj USB ua haujlwm tau zoo. Txawm hais tias qhov amperage tuaj yeem yog qhov siab dua, 500 mw cov zis yog qhov siv tau. Txiav qhov kawg ntawm lub xov tooj USB qub (lossis khaws qhov pheej yig) thiab rov qab ob peb ntiv tes ntawm cov yas npog. Sab hauv koj yuav pom 4 lub xov hlau, feem ntau yog nyob rau hauv cov hlua khi lossis nyias daim hlau. Cov xim hlau yuav dawb, ntsuab, liab, thiab dub. Txiav rov qab cov xov hlau dawb thiab ntsuab, tshem tawm me ntsis ntawm cov xov dub thiab liab, thiab muab lawv txuas rau cov xov hlau liab thiab dub ntawm chav peltier. Qhwv nrog daim kab xev hluav taws xob lossis siv lub raj cua sov. Yog tias koj xav tau cov ntaub ntawv hais txog cov txheej txheem kho kom raug lossis siv heatshrink tubing, muaj ntau ntau Cov Lus Qhia Zoo uas yuav muab txhua yam ntaub ntawv koj xav tau, tsuas yog tshawb nrhiav!
Xaiv tau, koj tuaj yeem txuas 1K txwv cov neeg nyob hauv nruab nrab ntawm cov xov tooj liab thiab dub, txawm hais tias koj muaj kev nyab xeeb heev ntawm qhov hluav taws xob thiab mA tsis xav tau tiag tiag. Tam sim no, ntsaws koj lub USB cable mus rau USB chaw nres nkoj ntawm koj lub PC, thiab hauv li ntawm 30 vib nas this koj yuav tuaj yeem hnov ib lub rhaub dej kub dhau los ua txias heev thaum lwm qhov ua kom sov. Nco tseg uas lub rhaub dej txias dhau, vim qhov ntawd yog yam peb yuav xav tau rau sab hauv lub tub yees txias.
Kauj Ruam 4: Tsim Lub Txias
Kuv siv foamboard vim tias nws yooj yim hauv kev txiav nrog xacto riam thiab nws cov khoom tsis zoo, thiab ib puag ncig tsim lub thawv nyob ib puag ncig lub rhaub dej kub siv rab phom kub kub txhawm rau txuas ob sab thiab sab saum toj, thiab tom qab ntawd tau khiav kab ntawm cov kua nplaum kub raws cov nqaws mus rau xyuas kom muaj qhov cua nkag. Cov hauv qab yog txiav ua ob ntu, nrog ntu plaub fab txiav tawm hauv plawv kom ua chav rau chav peltier. Tom qab ntawd kuv tau txuas ob lub kaum rau sab hauv qab ntawm lub rhaub dej txias, tom qab ntawd sab laug, nraub qaum, thiab sab xis ntawm lub tub yees, thiab thaum kawg sab saum toj. Saib daim duab hauv qab no:
Kauj Ruam 5: Kev Sib Ntsib zaum kawg thiab Kov Ntxiv
Kuv siv daim kab xev yas dawb los khawm lub qhov rooj, txawm hais tias koj tuaj yeem siv cov hinges me me los ntawm lub khw muag khoom kho vajtse thiab yooj yim lo lawv rau hauv qhov chaw nrog lub qhov rooj haum rau hauv ntej kom tsim nyog qhib thiab kaw. Kuv glued qhov ntev me me ntawm foamboard sab hauv lub tub yees sib dhos thiab tom qab ntawd glued txiav ib qho ntawm cov hlau nplaum hloov pauv hloov pauv ntawm ob sab hauv ntawm lub qhov rooj thiab lub foamboard ntev kom ua sib nqus "ntes" tuav lub qhov rooj kaw. Kuv kuj tau pov rau hauv lub roj teeb uas siv hluav taws xob dawb LED thiab siv cov nplooj hloov los tig lub teeb thaum lub qhov rooj qhib. Kuv tau khiav txoj hlua ntawm cov nplooj hloov mus rau sab hauv thiab dhau los ntawm lub qhov me me nyob rau sab nraum qab kom txuas rau AA lub roj teeb tuav rau sab nraud sab nraum qab ntawm lub tub yees, tom qab ntawd siv cov yas yas dawb ua raws cov xaim khiav, txuas rau sab hauv sab.
Rau tus kov kuv siv cov khoom lag luam pheej yig cov tub rau khoom tub rau khoom rub. Raws li koj tuaj yeem pom ntawm lub qhov rooj, Kuv xav kom qhov no zoo li lub khw "txias dua" uas koj pom rau cov dej haus, yog li kuv txiav lub qhov rais thiab kub glued ib ntu ntawm plexiglass hauv lub qhov rais.
Kauj Ruam 6: Qhov Kawg
Raws li koj tuaj yeem pom los ntawm cov duab, lub tshuab txias no yuav tuav cov fwj dej loj, lossis lub siab 20 oz yas yas fwj, txawm hais tias kuv cov dej haus uas kuv xaiv yog Starbucks Vanilla Frappucino! Lub txias yuav khaws cov dej haus li ntawm 45-50 degrees thiab ua haujlwm tau zoo tshaj plaws thaum koj haus dej twb txias lawm vim qhov pom tseeb. Xaiv tau, koj tuaj yeem siv 1 amp 7.5 volt DC adapter, uas yuav txo qhov ntsuas kub kom tsis tas ua kom lub rhaub dej kub qis dhau rau qhov tso rau ntawm qhov chaw ib txwm muaj. Hauv qhov piv txwv no, Kuv xav pom zoo kom koj ntxiv 1K limiting resistor txhawm rau ua kom DC adapter tsis txhob kub.
Kauj Ruam 7: Rhuav Tawm
Tam sim no, ntxiv cov duab los ntawm koj cov kev ua si nyiam lossis lub vev xaib thiab ua rau koj lub tub yees txias txias yog ib qho kev tsim zoo. Kuv tau luam tawm ntawm ib daim ntawv ntawm zaj duab xis pob tshab pob tshab los tsim cov pom los ntawm cov duab koj pom ntawm no. Muaj kev lom zem, thiab saib cov vis dis aus rau qhov xaus zoo …;)
