2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27
Hauv cov lus qhia no kuv yuav qhia koj li cas koj tuaj yeem ua rau koj tus kheej lub txhab nyiaj siv tau yooj yim muaj thiab cov khoom pheej yig. Lub roj teeb thaub qab no muaj 18650 li-ion roj teeb los ntawm lub khoos phis tawj qub lossis koj tuaj yeem yuav cov tshiab. Tom qab ntawd kuv tau ua cov ntoo ntoo nrog txias saib Plexiglas teeb kom muaj qhov txias zoo nkauj dua. Kuv yuav taug koj txhua qhov thiab txhua kauj ruam hauv kev tsim qhov no.
Saib cov vis dis aus kom nkag siab yooj yim
Cov lus qhia tshwj xeeb yog:
Peev Xwm: 6600mAh (nthuav tau)
Cov zis hluav taws xob: 5V
Kauj Ruam 1: Cov Ntaub Ntawv Yuav Tsum Tau
18650 li-ion roj teeb
TP 4056 roj teeb tiv thaiv module
6009 Boost Converter module
LED
330 ohm tiv thaiv
USB poj niam qhov (socket)
Cov khoom siv Soldering
Hloov
Plywood (3/4 "thiab 1/4" thickness)
Qee cov cuab yeej siv ntoo yooj yim xws li Laum, hacksaw, Chisel, thiab lwm yam
Kauj Ruam 2: Ua Lub Roj Teeb
Lub davhlau ya nyob twg ntawm 18650 roj teeb raug ntxuav siv IPA daws.
Ua ntawv thov me ntsis ntawm cov dej ntws thiab siv Cov Hlau Soldering tin saum npoo ntawm cov roj teeb dav hlau.
Tsis tas li hle lub rwb thaiv tsev ntawm cov xaim ntawm qhov kawg thiab tin lawv. Cov Roj Teeb yuav tsum txuas nrog hauv kev teeb tsa ua ke. Muab cov xov hlau txuas rau lub roj teeb thiab tsis txhob ua kom sov lub roj teeb ntau dua thaum siv cov laug.
Kuv lub roj teeb yog thawj Samsung ICR18650-22 tus qauv thiab kuv qhia koj kom siv cov roj teeb zoo kom ntev rau lub neej thiab kev nyab xeeb.
Kuv tab tom siv 3 lub roj teeb ua ke kom tau tag nrho Peev Xwm ntawm 6600 mAh. Koj yuav xav ntxiv roj teeb ntau dua ua ke kom muaj peev xwm ntxiv.
Tom qab khi cov roj teeb uas siv Hluav Taws Xob lossis kab xev kapton.
Nco tseg: Nws yog ib qho tseem ceeb kom them lub roj teeb rau tib theem hluav taws xob ua ntej sib txuas ua ke. Lwm lub roj teeb uas muaj peev xwm siab dua yuav tso tawm kom qis dua cov roj teeb thiab cov dej ntws loj dhau los ntawm lawv uas ua rau muaj cua sov ntau dhau.
Kauj Ruam 3: Roj Teeb Tiv Thaiv Circuit
Lub davhlau ya nyob twg ntawm cov roj teeb tiv thaiv module TP4056 tau qhia nrog cov cim.
Lub roj teeb yuav tsum txuas nrog B+ thiab B-terminals.
Cov zis tau txuas nrog Out+ thiab Out-terminals. Txhua lub xov tooj ntawm tes them nrog USB mini tuaj yeem siv los them lub roj teeb.
TP4056 module tiv thaiv lub roj teeb los ntawm kev them nyiaj ntau dua, tshaj tawm thiab luv Circuit Court. Cov roj teeb lithium yuav tsum tau ua tib zoo. Cov theem hluav taws xob yuav tsum nyob ntawm thaj tsam ntawm 2.7V txog 4.2V*. 2.7 V qhia 0% lub xeev them nyiaj thiab 4.2 V 100% lub xeev them.
Cov LEDs ntawm lub rooj tsav xwm qhia txog tus nqi ntawm lub roj teeb.
Liab LED - Them
GREEN LED - Them Tiav.
* qhov ntau tau hais yog rau roj teeb lithium ion thiab tuaj yeem sib txawv rau lwm hom roj teeb lithium.
Kauj ruam 4: Boost Converter Circuit
Xa cov duab rau kev sib txuas hauv Circuit lossis saib cov vis dis aus kom nkag siab yooj yim.
Txuas cov txiaj ntsig ntawm TP4056 module rau IN + thiab IN- ntawm kev txhawb nqa hloov pauv.
Ntxiv Kev Hloov Ua Ntej IN - davhlau ya nyob twg hauv series.
Kev ua haujlwm ntawm 6009 txhawb kev hloov pauv hloov pauv yog nce qib ntawm lub roj teeb (3.7 v nominal) kom ruaj khov 5 V.
Potentiometer (trimmer) ntawm qhov hloov pauv tau hloov pauv los teeb tsa qhov hluav taws xob rau 5V. Muab cov ntsuas ntsuas ntau lub meter tso rau qhov ntsuas kom ntsuas qhov hluav taws xob. Nco ntsoov tias qhov hluav taws xob tso tawm yog 5V ua ntej txuas lub xov tooj ntawm tes.
Nco tseg: Qhov tso tawm ntawm Boost Converter yuav tsum tsis txhob tshaj 5V.
Kauj Ruam 5: Kev Sib Txuas USB Tso Tawm
Cov zis ntawm kev hloov pauv tau txuas nrog USB poj niam lub mloog pob ntseg. Cov duab qhia pom tus pin teeb ntawm USB qhov (socket).
Kuv soldered USB mus rau ib qho ntawm pref-board thiab txuas cov xov hluav taws xob los ntawm qhov hloov pauv. Kuv kuj txuas ob lub Blue LEDS ua ke mus rau qhov tso tawm thiab nws tig ON thaum twg lub txhab nyiaj tau qhib. Daim duab qhia chaw yog nyob hauv cov duab txuas saum toj no.
Kuv de-soldered tus nqi taw qhia taw qhia SMD LEDs ntawm TP4056 tus qauv thiab siv qee qhov txuas txuas txuas thiab xaim RED thiab GREEN 5mm LEDs uas yuav raug teeb tsa ntawm rooj plaub.
Ua ntej mus rau kauj ruam tom ntej kuv tau sim yog tias lub Circuit Court ua haujlwm tau zoo los ntawm kev txuas lub Circuit Court rau kuv lub xov tooj ntawm USB Cable thiab nws Ua Haujlwm!
Kauj Ruam 6: Ua Ntoo Ntoo
Kuv tau sau tag nrho cov ntoo uas xav tau. Lub tswv yim yog kom khawb ib lub qhov rau ntawm 3/4 ply ntoo nrog 1 cm phab ntsa ntawm txhua sab.
Tom qab ntawd ib daim ntawv nyias ntawm plywood tau npog rau ob sab kom nws zoo li lub thawv.
Lub qhov kom teeb tsa coj thiab txuas USB tau ua tiav ntawm 3/4 plywood. Raws li ib feem ntawm kev zoo nkauj xav tias kuv xav ntxiv cov ntawv acrylic rau ntawm ib puag ncig ntawm lub npov thiab coj teeb nws thaum twg los xij hloov. Yog li kuv txiav txim siab txiav 4 daim ntawm 1 cm txhua thiab lo rau ntawm ntoo.
Yog tias koj xav tau kuv lub thawv me me yog 11cm*9.5cm. Qhov no yuav txawv raws li koj tsim thiab pes tsawg lub roj teeb.
Tom qab ntawd kuv tau txhuam cov ntoo siv 100 daim ntawv xuab zeb thiab siv 2 lub tsho ntawm cov ntoo txhuam siv cov ntaub qhwv los ua kom zoo nkauj.
Kauj Ruam 7: Sib dhos
Kuv tau sim yog tias lub Circuit Court ua haujlwm thiab tau kaw tag nrho cov khoom siv hauv cov ntoo siv cov kua nplaum kub.
Tom qab ntawd kuv siv qee cov kua nplaum ntoo los txuas rau lwm daim plywood kom ua tiav kev sib dhos thiab kaw nws kom txog thaum cov kua nplaum tau qhuav. Koj tuaj yeem xa cov duab ntawm yuav ua li cas kuv tau teeb tsa lub Circuit Court.
Kuv tau siv lub txhab nyiaj fais fab no rau 2 lub lis piam tam sim no thiab kuv tau siv nws zoo Kuv tuaj yeem them kuv lub xov tooj ib zaug. Kuv xav tias qhov no tuaj yeem txhim kho yog tias siv cov roj teeb tshiab.
Kuv kuj qhia kom siv cov khoom siv fais fab uas tau npaj ua yog tias koj xav cawm koj tus kheej los ntawm Kev Siv Tshuaj thiab qhov los nrog cov ntaub ntawv zoo ib yam li kev lag luam. Tab sis kuv xav tau hom kev cai ua lub txhab nyiaj uas tsis tsuas yog ua haujlwm tau zoo tab sis kuj zoo li txias!
Thov tawm lus yog tias koj hla qhov kev ua xyem xyav lossis koj muaj lus qhia.
