Video: Sib nrug ib qho Optical Mouse: 7 Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:30
Dr Destruct-o sib nrug ob peb Microsoft Explorer Optical "IntelleMice", los saib seb puas muaj cov txiaj ntsig zoo nyob hauv.
Kauj Ruam 1: Ntawm no Peb Muaj Ob Tus Tseem Tseem Nyob Ua Ke
Cov no zoo li tshwm nrog qee qhov tsis tu ncua hauv E-pov tseg cov chaw ua haujlwm. Kuv tsis paub yog tias Microsoft nas feem ntau tsis ua hauj lwm ntau dua li nas, tab sis lawv yeej paub ntau dua hauv cov thoob khib nyiab.
Ib qho ntawm no hais tias "version 3" ntawm daim ntawv nplaum hauv qab, thiab lwm qhov tsis yog. Lawv yog USB nas, txawm hais tias pom tseeb lawv yuav tham PS2 ib yam nkaus, siv lub cev hloov pauv nkaus xwb (cov hloov pauv no tsis txhais tau tiag tiag ntawm PS2 thiab USB cov txheej txheem, lawv tsuas yog txuas cov xov hlau sib txawv. ntawm kev txuas tau siv, thiab rov kho nws cov koob raws li qhov tsim nyog.)
Kauj Ruam 2: Nrhiav thiab Tshem Tawm Cov Ntsia Hlau
Ntau yam "cov neeg siv khoom" nrog "tsis muaj cov neeg siv khoom siv tau sab hauv" yuav zais lawv cov ntsia hlau, ob qho tib si kom tsis txhob sib dhos, thiab ua kom cov khoom zoo dua. Hauv qhov no, muaj plaub lub ntsej muag zais hauv qab me me teflon "slider" pads hauv qab ntawm nas. Cov ntaub qhwv tuaj yeem raug txiav tawm nrog rab riam lossis lub taub hau me me, nthuav tawm ib txwm siv lub taub hau philips.
Kauj Ruam 3: Tshem Mouse Guts
Thaum cov ntsia hlau raug tshem tawm, sab saum toj thiab hauv qab ntawm nas cais yooj yim dua. Txij li thaum kuv tsis tau npaj rau muab lawv rov qab ua ke, Kuv tsis tau ua tib zoo mloog; qee zaum muaj cov khoom yas sib cuam tshuam uas koj tsis xav tawg yog tias koj tau sim kho dua li khaws cia …
Ob tus nas, txawm hais tias sab nrauv "zoo ib yam", muaj qhov sib txawv sab hauv. Ib qho ntawm cov duab ntawm no muaj peb daim phiaj xwm txheej, thiab qee qhov ntsia hlau ntxiv los tshem tawm. Lwm tus (laus dua?) Nas tsuas muaj ob lub laug cam, thiab tau muaj nws sab hauv tuav ua ke nkaus los ntawm cov yas tab thiab qhov qhib.
Kauj Ruam 4: Yog li Peb Tau Txais Dab Tsi? Clippable thiab Unpluggable: LEDs thiab Cables
Yog li puas muaj dab tsi sab hauv uas peb siv tau? Thiab ua li cas txog kev nyiag nas kom nws ua qee yam tsis tau xav txog? Txhawm rau pib nrog, muaj cov LEDs.
1) Ob lub ultrabright liab LEDs, nrog cov coj zoo nkauj ntev. Ib qho ntawm cov no yog "Tail" LED, uas tsis muaj lub hom phiaj uas tsis yog "kos duab." Tail LED tuaj yeem hloov nrog lwm cov xim LEDs, lossis LEDs uas ntsais. Lossis koj tuaj yeem tshem nws tawm thiab nas yuav tsum ua haujlwm txuas ntxiv yam tsis muaj nws. Cov LEDs no muaj cov coj ntev txaus uas koj tuaj yeem zaum tsuas yog txiav lawv nrog cov xaim txiav thiab siv lawv mus rau lwm qhov; tsis muaj de-soldering yuav tsum tau. 2) Nws yog qhov tu siab me ntsis, tab sis qhov tseeb, uas qee zaum qhov muaj txiaj ntsig zoo tshaj plaws uas koj tuaj yeem tawm ntawm ib qho ntawm cov khoom siv hluav taws xob niaj hnub no yog me ntsis xaim. Hauv qhov no, nas muaj ib txoj hlua zoo nrog USB txuas ntawm ib kawg thiab me ntsis PCB txuas ntawm lwm qhov. USB ntsaws yog qhov muaj txiaj ntsig zoo ntawm lub hwj chim rau kev siv hluav taws xob, yog li cov kab no, nrog kev hloov kho me ntsis, tej zaum yuav yog ib qho ntawm cov khoom siv tau zoo dua hauv nas. Tshem tawm ntawm nws cov rwb thaiv tsev sab nraud thiab sib cais ua ib tus neeg nyob ib leeg, peb muaj qhov tshwj xeeb uas hloov pauv tau cov hlua uas muaj cov hlua khi, uas muaj txiaj ntsig zoo rau txhua yam ntawm "hnav" cov khoom siv hluav taws xob.
Kauj ruam 5: Yooj yim Desolderable
Qee cov khoom siv tau yooj yim dua los ntawm PCB dua li lwm yam. Qhov hla qhov nrog peb tus pin lossis tsawg dua yog qhov yooj yim tshem tawm siv cov kab laug sab, piv txwv.
1) Txhua ntawm cov nas no muaj tsib qhov kev hloov pauv me me; zoo heev SPDT cov uas yuav muaj txiaj ntsig 2) Lub tshuab xa hluav taws xob thiab "ntsuas lub ntsuas" ua ib feem ntawm lub log nas. Hauv lub log nas, uas tseem yog kho qhov muag, muaj ob txoj hauv kev ua ib qho infrared LED, thiab plaub-ntu ntu uas yog ob daim duab-transistor lossis (tej zaum) ntau txoj hauv kev nyuaj uas tso tawm cov teeb meem nyuaj rau microcontroller qhia txoj kev twg uas lub log log (tig nrog lub log nas) tig. Qhov no yog txhua yam ntawm pawg cais zoo; nrog kev txawj siv tshuab me ntsis koj yuav tuaj yeem siv lub log cais los ntawm tus nas tas li. 3) Tus tshiab version ntawm tus nas muaj peb tus pin 6MHz (ib qho nrawm rau USB yam) ceramic resonator zais hauv qab cov hlau tuaj yeem ua tau. (Peb tus pin resonator hloov pauv siv lead ua thiab ob lub kaus mom hauv feem ntau microcontroller circuits.) Cov laus dua muaj ob 2-pin resonators (qee yam tsis tshua muaj txiaj ntsig IMO.)
Kauj Ruam 6: Nyuaj Tshaj Kom Tau Txais: Chips thiab SMT Cheebtsam?
Qhov ntawd tawm ntawm cov khoom nyuaj nyuaj rau tshem tawm. SMT cov khoom thiab cov khoom uas muaj ntau tus pin. Koj tuaj yeem nres ntawm qhov no, tshwj tsis yog muaj qee yam koj xav tau tiag tiag.
Muaj qee cov chips nthuav, tab sis lawv tsis muaj txiaj ntsig zoo li cov chips rau cov nyiam ua haujlwm. Cov cuab yeej kho qhov muag tau hais tias yuav siv tau raws li lub koob yees duab daws teeb meem qis (32x32 pixels?), Tab sis hauv qhov tshiab ntawm nas, lub koob yees duab thiab microprocessor tau muab tso ua ke tib yam "nas ntawm lub nti", yog li tej zaum lub koob yees duab yog nkag tsis tau ntxiv lawm. USB microcontroller ntawm tus nas laus zoo li yog tus qauv Cypress me ntsis, tab sis tej zaum tsis tuaj yeem rov tsim dua. Cov ntim tau meej "Mouse on a Chip" zoo nkauj heev li cov chips mus. Nws yuav ua kom nthuav cov hniav nyiaj hniav kub. Kuv tswj kom tau nws tawm ntawm lub rooj tsavxwm los ntawm kev ua kom sov tag nrho txhua yam hla cov pa taws ntawm sab nraub qaum ntawm lub rooj tsavxwm kom txog thaum txhua yam tau kub hnyiab thiab cov laug tau yaj, thiab tom qab ntawd THWACKing ntawm qhov tawv tawv. Lub tsev tsis hnov tsw phem rau ib lub lim tiam, txawm tias lub tshuab ntxhua khaub ncaws; yam khoom no yuav tsum tau ua sab nraud yog tias koj yuav ua nws.
Kauj Ruam 7: Xaus…
Ua tiav! Vam tias kuv tuaj yeem xav txog qee yam muaj txiaj ntsig ntxiv los hais.
