Kuv tsis paub txog koj, tab sis kuv tuaj yeem paub tseeb silicone los ntawm qhov tiag. Nov yog yuav ua li cas pov cov jelly thiab nyem qhov ib txwm siv -caps-thiab-springs ntaus USB keyboard rau hauv OLPC XO laptop. Qhov no yog "theem I" - tau txais cov keyboard rau hauv ib nrab ntawm rooj plaub, tab sis tawm hauv USB cable txuas nrog rau sab nraud USB chaw nres nkoj (Hloov tshiab: Phase II qhia tam sim no tshaj tawm). Kev phais mob rau qis ib nrab ntawm XO yog tsim nyog, yog li koj li OLPC yuav tsis zoo ib yam yog tias koj ua qhov no. Kuv tau ua nws vim tias kuv muaj ntau lub log Dremel ntawm kuv txhais tes thiab kuv XO yog qhov yooj yim dua los txiav qhov hauv dua li kuv tus neeg nyob ze lub tsheb. Leej twg xav cuam tshuam nrog txuas txuas txuas ntxiv thiab muaj peev xwm ua rau huab cua tsis zoo? Tsis tas li vim tias kuv XO cov keyboard ua tsis tiav - Ctrl tus yuam sij tau nyam - tom qab 30 hnub lav lub sijhawm twb tau tas lawm. Yam koj yuav xav tau: 1. Cov keyboard tshiab (saib cov kauj ruam 1) 2. Dremel cuab yeej lossis sib npaug hauv hws thiab mob 3. Cov hniav nyiaj hniav kub loj phillips ntswj ntsia hlau, lossis ib qho ntawm cov khoom pub dawb ob zaug uas lawv siv los muab rau ntawm IT-cuam tshuam nrog cov lus pom zoo4. Ntau daim kab xev cellophane (lossis ntau pua tus neeg pab me me uas tsis quav ntsej raug kaw hauv koj XO mus ib txhis) 5. Ib qho hlau uas tsis xav tau (xaiv tau) 6. XO lub laptop los ntawm OLPC, nyiam dua ib qho uas muaj teeb meem keyboard.
Kauj Ruam 1: Txiav Koj Cov Keyboard Tshiab
Koj kinda hafta xaj cov keyboard ua ntej. Txwv tsis pub, koj yuav cais koj XO, thiab pawg ntawm cov khoom yuav maj mam noj rau hauv koj lub siab tsis nco qab nrog subliminal nagging: "Kuv siv los ua lub khoos phis tawj," thiab "Koj tsis tau ua tiav ib yam dab tsi," thiab thaum kawg "Thov … tua … kuv … "Tej zaum nws tsuas yog kuv cov phiaj xwm uas hais tej yam zoo li ntawd." Super Mini USB Keyboard "ntawm CyberGuys.com suab zoo li kev sib tw raws li kev tshaj tawm kev ntsuas. Thaum lub npov tuaj txog hauv ntawv, pob tau tshaj tawm tias nws yog "ASK-3100 Series Ultra Mini Keyboard," suav nrog "tus tsim ntawm txiab txiab keycaps." Kuv tsis yog kws kes duab vajtse, tab sis ASK-3100 Series Ultra Mini yog ze ze haum zoo thiab zoo nkauj zoo ntawm $ 32 (ntxiv rau xa khoom). Kuv tsis quav ntsej rau npe rau "tus yuav lub club" kom tau txais 5% ntxiv. Sau npe kom tau 5% ntxiv! Nov yog qhov URL:
Kauj ruam 2: Qhib Keyboard
Nws yog lub sijhawm los tshem rooj plaub ntawm ASK-3100 Series Ultra Mini Keyboard. Muaj yim qhov ntsia hlau nyob hauv qab ntawm cov keyboard, tab sis peb ntawm lawv tau nkaum ntawm koj tus ntsia hlau. Ob ntawm cov ntsia hlau tsis zoo no nyob hauv qab cov roj hmab taw mus rau pem hauv ntej ntawm cov keyboard; tev lub taw tawm nrog koj tus ntiv tes xoo lossis tus pas nrig. Lwm qhov yog tom qab daim ntawv lo cim "TSIS TXHOB tshem tawm." Koj paub yuav ua li cas.
Thaum koj muaj lub plhaub tawm, koj yuav tsum tau txuas txoj hlua hlua ntawm cov keyboard thiab nws daim npav tswj. Tab sis tos! Tshwj tsis yog tias koj tuaj yeem tsim cov duab origami thawj hauv koj lub taub hau, koj yuav tsum nqa tus cwj mem thiab cim ob lub xov tooj thiab txuas nrog lub cim asymmetrical, zoo li tsab ntawv "F," nyob qhov twg lawv tuaj ntsib. Qhov ntawd yuav pab koj tom qab thaum koj yuav tsum tso lawv rov qab ua ke ib yam li lawv tau pib tawm. Lub rooj sib tham me me nrog lub kaus mom xauv, tus lej xauv, thiab xauv xauv LEDs ntawm nws yog daim npav tswj hwm. Ribbon cable tab tom yuav muaj hnub tsis zoo, yog li rub nws maj mam rov qab los ntawm qhov txuas.
Kauj Ruam 3: Tsis Rhuav Tawm? Yog! Muab pov tseg
Kuv yuav tsum tau xav txog qee yam txhawm rau txhawm rau nkag siab qhov haujlwm ntawm tes. 1. Koj nyeem tau. 2. Koj tuaj yeem tshawb xyuas wiki.laptop.org. Assuming 1. thiab 2., koj yuav tsum muaj peev xwm mus rau https://wiki.laptop.org/go/Disassembly thiab nyeem cov ncauj lus kom ntxaws thiab ua tiav cov lus qhia ntawm kev cais koj XO. Rau Phase I ntawm txoj haujlwm no, koj tsis tas yuav siv ib nrab ntawm koj XO sib nrug, tsuas yog siv cov keyboard. Thaum koj ua tiav txhua yam sib nrug, koj yuav muaj XO "taub hau" ntsaws ob txoj hlua. Lub taub hau tseem yuav ua haujlwm ntawm AC lub zog, raws li pom hauv thawj daim duab, tab sis hauv qab ntu zoo nkauj npaum li tsis ua dab tsi ntawm qhov no. Ntawm no kuv ua kom ntseeg tau tias cov keyboard ua haujlwm. Kuv tsis nco qab ua qhov ntawd ua ntej kuv hais nws qhov kev lees paub, tab sis hmoov zoo nws tsis muaj teeb meem.
Kauj Ruam 4: Tsis muaj dab tsi hloov tsis tau
Piv txwv tias koj tsis tau ua txhaum ib qho ntawm koj lub khoos phis tawj sim ua kom nws sib nrug, cov kauj ruam tom ntej no yuav yog thawj qhov kev puas tsuaj tiag rau koj XO. Yog tias koj nres tam sim no thiab tso koj XO rov qab ua ke, koj tus dev yuav tsis xav txog koj tsawg dua, tab sis qee tus ntawm peb cov tsiaj nyaum yuav ua rau nrov nrov nrov feem ntau cuam tshuam nrog kev thuam. Mus tu koj tus dev, koj yuav zoo dua.
Nco ntsoov tias thawj cov keyboard ntawm kab xov kab hluav taws xob raug cais los ntawm nws lub rooj sib tham, thiab ntawm no peb mus: ua haujlwm koj cov rau tes (lossis ntiv tes taw) hauv qab txhua peb txheej ntawm cov keyboard, tom qab ntawd tev nws rov qab. Nws yuav tsum tuaj nyob rau hauv ib daim ntawv, tawm tsuas yog cov nplaum nplaum ntawm qhov tsis pub hnav lub cev pob txha ntawm koj XO. Kuv tau ua kuv li thaum lub cev tsis muaj lub taub hau ntawm kuv XO saib hauv kev ntshai. Muahahaha. Ha ha haaaaaaaa. Ha. Muab cov keyboard tshiab tso rau qhov qub. Koj yuav pom daim kab xev yuav luag nyob ntawm qhov chaw raug kom dhau los ntawm tib qhov zoo ib yam li cov keyboard qub tau ua - tab sis tsis zoo li.
Kauj Ruam 5: Ua Lub Qhov
Peb nyob qhov twg? Auj, txoj cai; ua ib lub qhov rau cable kom dhau mus.
Tej zaum nws tsis yog qhov kev xaiv zoo tshaj plaws, tab sis kuv txiav txim siab kom yooj yim nthuav dav cov kab uas twb muaj lawm los ntawm kev koom nrog nws nrog qhov nyob ze. Lub qhov ntawd dhau los ua qhov twg yog qhov sib txuas zoo li tus pegs nyob hauv qab lub touchpad latch rau, yog li ua raws li kuv qhov piv txwv yuav tawm ntawm koj thaj tsam touchpad nyo hau (saib daim duab kawg). Tawm los Dremel cov cuab yeej, thiab ntawm 15k RPM, kev txiav tau ua nrawm. Koj puas nco tau koj lub tsom iav kev nyab xeeb? Koj yuav xav tau daim npog ntsej muag ib yam, yog tias koj nyiam koj lub ntsws. Ua li cas los xij, khaws tej yam zoo li koj lub qhov muag tawm ntawm txoj kev ntawm lub txim taws; yog tias lub disk tawg lossis nws ncaws tawm qee yam ntau dua li lub teeb zoo nkauj, koj yeej tsis xav kom muaj kev pheej hmoo pom koj. Koj kuj tseem yuav tsum ua kom cov hlua hlua tsawg dua qhov hnyav; txiav tawm cov yas ntshiab ntau dhau tom qab khoov hauv cov neeg ua haujlwm. Tsis txhob txiav hla ib qho ntawm cov xov ci ci! Tom qab koj muab lub cable zoo dua lub luj tshib, koj yuav xav txhawb qhov tob tshaj plaws ntawm kev txiav nrog qee daim kab xev cellophane kom nws tsis txhob los kua muag. Txawm tias koj tus dev yuav luag yog tias koj yuav tsum tau yuav lwm tus $ 30 cov keyboard vim tias koj tau yaim ob peb tus neeg ua haujlwm hauv cov hlua kab. Thaum kawg, hloov mus rau koj qhov khawb me ntsis ntawm koj Dremel thiab nibble tam sim ntawm tus ncej uas xav tias yuav hla lub qhov uas koj cov hlua txuas tam sim no. Txwv tsis pub, tej yam tsis zoo tuaj yeem tshwm sim thaum koj muab rooj plaub rov qab los ua ke. Koj yeej tsis tas yuav rov kho cov kab xev punched ua ib feem ntawm txoj haujlwm no. Koj kuj tseem yuav xav kom tshem cov yas yas dub rau saum cov keyboard, kom tso cov yas dawb tso rau saum cov keyboard kom haum rau hauv nws lub qhov.
Kauj Ruam 6: Keyboard Controller Nrog Txhua Qhov Txiav
Koj yuav tsum tau txiav cov keyboard tswj tshiab. Kuv tuaj yeem txaus siab rau koj li vib nas this nrog cov dab neeg ntawm ntau txoj hauv kev kuv nrhiav kom haum tus tswj hwm rau XO cov ntaub ntawv yam tsis tau ua cov no, tab sis thaum nws yuav zoo siab rau koj lub siab, nws yuav ua rau kuv los kua muag, yog li cia peb hla nws.
Koj yuav tsum tau tshem ntawm qhov taw qhia LED teeb ntawm tus tswj; lawv siab dhau lawm. Kuv tau mus rau qhov teeb meem ntawm desoldering lawv, tab sis koj tuaj yeem zaum tsuas yog siv ob txoj hlua hlau txiav thiab snip los ntawm lawv. Koj kuj tseem tuaj yeem de-solder thiab txav cov khoom ntawm lub rooj tsavxwm kom lawv txhua tus nyob ib sab, lossis txiav tawm qee qhov ntxiv ntawm PC board thiab txuas tsev. Kuv kuj tau txiav tag nrho cov ntsiab lus (qhov ntse kawg ntawm cov xov hlau tawm sab hauv qab ntawm lub rooj tsavxwm) Kuv tuaj yeem ua tau. Thaum kawg, npuaj ib yam dab tsi uas tsis yog tus coj (ntawm no kuv tau siv qee daim kab xev phom) hla daim npav txhawm rau tiv thaiv nws los ntawm kev ua luv luv.
Kauj Ruam 7: Ua Lub Qhov Ntshai Loj
Tom qab koj tau txais koj cov keyboard tswj tshiab kom loj, qhov khoom phem tiag tiag pib tshwm sim rau koj XO. Daim npav tswj hwm tau yuag txaus kom haum rau lub quarter-inch tuab cov ntaub ntawv keyboard uas koj tau muab pov rau hauv cov kauj ruam 2, tab sis XO lub hauv paus yog qhov zoo kawg (nyuaj siab!) Nyias. Tsis txhob poob siab, tsuas yog ua lwm qhov.
Lub sijhawm no nws yuav yog cov keyboard-tswj qhov loj me hauv cov phaj hlau cov keyboard tau zaum. Lub qhov yuav offset qee qhov tuab ntawm tus tswj kom XO cov ntaub ntawv yuav raug kaw dua. Yay. Teem daim npav ntau dua lossis tsawg dua nrog cov hlua kab, taug ib puag ncig nws, tom qab ntawd txiav raws kab kab. Ntxiv qhov qhib ntxiv rau kab xov kab xev kom nws tsis txhob tawg tawm tsam daim npav. Kuv siv plaub lub log Dremel txiav kuv tus kheej. Vam tias koj tuaj yeem ua tau zoo dua. Nco ntsoov tias koj de-burr cov npoo, tshwj xeeb tshaj yog nyob ib puag ncig qhov chaw ntxiv uas koj tau muab rau kab, yog li kev sib cuag nrog nws nrog cov hlau yog qhov zoo thiab du. Yog tias koj xav kom muaj kev nyab xeeb ntxiv, npog cov hlau nrog ib daim kab xev cello. Dremel tshem tawm "cov tav" khiav nrog sab hauv ntawm rooj plaub uas tsis sib xws ntawm daim npav tswj hwm, yog li daim npav yuav muaj chav me me ntxiv ntawm sab ntawd, ib yam nkaus. Khiav lub USB cable nce thiab tawm ntawm rooj plaub, ua raws cov kab txuas trackpad, thiab lo txhua yam rov qab rau hauv qhov chaw. Kuv siv ntau daim kab xev cello. Tsis ntxim nyiam? Luckily tsis muaj leej twg yuav pom qhov no ntxiv. Koj txoj haujlwm tiav lawm! Hu rau koj tus kws phais neeg kaw kom rov sau dua XO. Nco ntsoov koj cov npoj yaig tias cov xaum yuav tsum tuav kom nruj, vim tias tus neeg mob muaj lub siab tshiab thiab loj dua. Kuv xav pom zoo kom pub USB cable nyob ib ncig ntawm pob khawm thiab tawm ntawm lub pob khawm npog tam sim no.
Kauj Ruam 8: Txuas Nws
Coj tus USB cable dai tawm ntawm pob khawm ntawm koj XO thiab ntsaws rau hauv, zoo, koj XO. Tau kawg, koj tseem tuaj yeem ntsaws nws rau hauv koj tus phooj ywg lub computer thiab ua piv txwv tias koj tsis paub dab tsi txog plaub-tsab ntawv cov lus tshwm ntawm nws lub vijtsam, thiab rau quaj nrov nrov vim li cas nws thiaj tsis tuaj yeem cia koj ua haujlwm koj lub khoos phis tawj nyob nyab xeeb? Qhov ntawd yog tam sim no. Thaum kuv tau txais lub sijhawm kuv yuav sim ua qhov no mus rau cov kauj ruam tom ntej; theem II yuav suav nrog kev siv USB cable rau hauv XO lub taub hau thiab txuas nws mus rau ib qho ntawm USB chaw nres nkoj ncaj qha.
