2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Nov yog qhov hloov kho tshiab ntawm cov ncauj lus qhia ntxaws los ntawm cov cuab yeej tsim khoom no, Ladyada. Qhov hloov kho tshiab muaj qee yam ntxiv. Cov lus nug txog lub cuab yeej no yuav tsum hais ncaj qha rau Ladyada cov rooj sab laj, thiab qhov phiaj xwm qhov chaw muaj qhov zoo sib xws li cas. Version 1.1 thiab laus dua muaj PCBs ntsuab, thiab version 1.2 yog txhua yam dawb. Tsuas yog qhov sib txawv loj hauv 1.2 yog qhov R5 resistor tso rau. Kauj ruam plaub ntawm resistors muaj cov ntaub ntawv ntau ntxiv txog nws. Tsis tas li ntawd, koj tuaj yeem ua raws cov lus qhia txuas ntxiv yam tsis muaj kev txhawj xeeb. Hauv version 1.2, kev hloov kho tau yooj yim dua. Koj tuaj yeem yuav cov khoom siv v1.2 ntawm MAKE khw. Txhawm rau kawm cov hauv paus ntawm kev siv tshuaj xyuas kos tawm phau ntawv qhia no los ntawm noahw. Tsis tas li, ntawm no yog cov vis dis aus zoo los ntawm MAKE blog.

Kauj Ruam 1: Yam Koj Tau Txais thiab Yam Koj Xav Tau

Cov npe ntawm no yog rau ntu los ntawm cov khoom siv V1.1. Tsuas yog qhov sib txawv tiag tiag yog ob tus tiv thaiv. Koj tau txais cov khoom siv li cas: 1 x IC1 MAX746 nrog Socket2 x C2, C3 Lub Hwj Huam Muab Khoom Capacitor2 x C1, C4 Bypass Capacitor2 x R4, R5 10k.25W Resistor1 x D1 Schottky Diode1 x L1 Fais fab Inductor1 x X1 USB Poj niam Jack 1 x Roj teeb Holder 1 x PCBWhat Cheebtsam koj yuav xav tau: 2 AA roj teebWhat cov cuab yeej koj yuav xav tau. Rosin core, 60/40 solderSoldering Iron vam tias nrog tus xaum zoo li lub taub hauWire clippersA lwm los tuav lub PCB (Koj tuaj yeem tau txais txhua yam khoom no pheej yig tiag tiag ntawm https://www.all-spec.com/ lossis

Kauj Ruam 2: Capacitors, Diodes

Cia ua ntej siv cov xim xiav thiab cov diode. Vim li cas peb thiaj ua cov no ua ntej - vim tias kev taw qhia tseem ceeb. Txheeb tawm cov duab kom pom kuv txhais li cas.

Cov capacitors xiav muaj kab txaij uas yuav tsum tau ua tib yam li cov kab txaij ntawm PCB. Koj tseem tuaj yeem ua raws + ntawm lub rooj tsavxwm. Qhov ntev dua ceg ntawm lub capacitor yog qhov zoo. Lub diode muaj kab txaij ntawm nws ib yam nkaus, thiab nws ib yam nkaus yuav tsum ua kom haum nrog cov ntawv luam tawm ntawm PCB. Muaj ib daim duab super-ze los pab. Khaws cov khoom no tso rau hauv, thiab khoov cov hlua xov nyob ib puag ncig nraub qaum me ntsis kom lawv tsis poob tawm thaum koj tig lub rooj tsavxwm. Muab lawv tso rau hauv zoo thiab txiav cov tails ntau dhau.

Kauj Ruam 3: Cov Cheeb Tsam Ntau

Hauv qhov zoo ib yam ntxiv cov xim daj thiab qhov loj, roj inductor. Ua raws cov duab rau kev tso kawm.

Ib zaug ntxiv, muab cov khoom tso rau hauv pawg thawj coj saib, khoov cov xov hlau rov qab me ntsis, cov laug, thiab txiav cov xov hlau ntau dhau.

Kauj Ruam 4: Resistors & Cov Lus Cim Tshwj Xeeb

Version 1.2 (dawb PCB) ua rau teeb tsa Minty Boost rau cov cuab yeej tshiab yooj yim dua, txij li R5 resistor muaj ob txoj kev xaiv tso rau. (Saib cov duab) Tus tsim qauv qhia kom tso tus tiv thaiv rau hauv "rub tawm" txoj haujlwm (daim duab kawg) kom zoo tshaj plaws. Txawm li cas los xij, yog tias qhov ntawd tsis ua haujlwm koj ib txwm tuaj yeem kaw qhov xaim thiab sim qhov "pulldown" txoj haujlwm. Kev tiv thaiv tus tiv thaiv raws li pom hauv thawj daim duab, thiab lo lawv rau hauv lawv qhov chaw nruj, R4, R5. Ua raws cov txheej txheem txheej txheem siv hauv lwm cov kauj ruam. Nco ntsoov, ua raws R5 txoj haujlwm rub tawm ua ntej tshwj xeeb tshaj yog tias koj muaj iPod tshiab (qhov no tau sau thaum Lub Caij Nplooj Ntoos Zeeg 2007). NOTE rau V1.1: Yog tias koj muaj lub tshuab MP3 tshiab zoo li iPod nano 2G (cov hlau me me), Shuffle 2G (hlau clip), Zune player, lossis yog tias koj tsis tau txais koj lub cuab yeej los them nyiaj thaum koj ua tiav kev tsim qhov no, koj yuav tsum hloov kho cov khoom tiv thaiv me ntsis. Nws yooj yim zoo nkauj tiag. Ib ceg ntawm R5 resistor tuaj yeem muab txuas rau + zog sib cuag. Saib cov duab kawg kom paub meej.

Kauj ruam 5: USB thiab IC

Tom ntej no, USB nkaus yuav tsum mus ntxiv. Kuv ua tau clip hauv yog li koj tsis tas yuav txhawj txog nws poob. Khaws nws rau thiab muab tshuaj txhuam. Tus neeg siv LasVegas qhia tias txawm tias muab cov kauv tso rau hauv: "Txhawm rau kom ruaj khov rau USB-B txuas, Kuv xav kom" klaws "raug muab tso rau hauv qhov ib yam. xoob thiab ua rau muaj kev sib txuas tsis zoo. " Tom qab ntawd, ua raws nrog IC qhov (socket), uas xav tau kab nrog U ntawm PCB. Saib daim duab kom ntxaws, thiab txoj cai tib yam no siv rau IC nws tus kheej, uas tseem muaj U me ntsis kos rau ntawm nws.

Kauj Ruam 6: Lub Hwj Chim Tau Los

Thaum kawg, cov xaim hluav taws xob yuav tsum tau muab tso rau hauv qhov chaw. RED = +BLACK = -Again, ua raws cov duab. Yuav luag tiav! Nco ntsoov tias yog koj xav hloov kho qhov no los ua haujlwm nrog cov neeg ua si tshiab, koj yuav tsum txuas R5 tus tiv thaiv tam sim no ib yam nkaus.

Kauj Ruam 7: Xeem Nws

Yog tias koj muaj lub multimeter ua ke: Muaj qhov sim yooj yim kom ntseeg tau tias nws ua haujlwm. Ladyada piav qhia nws kom ntxaws hauv cov lus qhia qub. Cov hauv paus yog: tau txais lub multimeter teeb nws los ntsuas qhov ntsuas hluav taws xob (V nrog kab ncaj) kov ob tus neeg ntawm USB nkaus. Kev nyeem ntawv yuav tsum yog 5V. Kos daim duab hauv qab no. Koj yuav tsum thawb cov neeg sib cuag nrog qee lub zog.

Kauj Ruam 8: Txiav lub Tin

Tiav lawm! Thawj qhov kev qhia qhia yuav ua li cas txiav cov tin hauv ntau yam. Yog li koj yuav tsum tau mus tam sim no. Thiab tseem muaj lwm txoj hauv kev uas ua rau chav nyob ruaj khov ntawm no.
