Ua Tus Neeg Kho Tshuab Numpad: 4 Kauj Ruam

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:28

Kuv muaj IBM USB tus lej qub zaum ib puag ncig khaws cov hmoov av thiab thaum tseem siv tau, nws muaj cov roj hmab dome membrane tuav. Thaum tsis yog kev cuam tshuam-cuam tshuam, Kuv tau xav kom nkag mus rau kev cai cov twj siv hluav taws xob thiab qhov no yog kev qhia zoo.

Cov Khoom Siv:

1 Pub tus lej USB

17 Cherry hloov pauv hloov ntawm koj xaiv (Kuv siv Kailh Box Whites)

17 1N4148 dhau ntawm qhov diode

1 3D rooj plaub luam ntawv (Kuv siv tus qauv no nrog qee qhov kev hloov pauv me me:

1 Teeb ntawm keycaps (Kuv siv cov no)

1 Teeb ntawm phaj-mount stabilizers. Koj yuav xav tau 32u stabilizers.

4m3 cev

Kauj Ruam 1: Dissasemble thiab Reverse Engineer the Matrix

Tshem tawm cov tswj hwm pawg thiab cov lej los ntawm tus lej lej thiab saib seb cov khoom raug teeb tsa li cas.

Roj hmab dome qhov tseem ceeb hloov pauv ua haujlwm los ntawm kev sib txuas lus ntawm txhua txheej ntawm matrix ua ke. Lub hom phiaj hauv qhov kev tsim no yog rov ua dua cov qauv qub no tab sis nrog cov khoom siv sib hloov.

Cais peb daim ntawm cov lej thiab pov tseg qhov khoob, nruab nrab daim.

Txhua tus dot ntawm lub matrix sawv cev rau kev hloov pauv, ntawm tus lej lej nws yooj yim zoo nkauj los taug qab seb yog dab tsi.

Kuv tau hla mus thiab sau cov kab twg/kab ntawv mus rau tus pin ntawm tus tswj hwm pawg thawj coj saib. Qhov no tuaj yeem ua tiav tsuas yog ua raws cov kab rov qab mus rau lub ntsaws ntawm lub rooj tsavxwm thiab sib piv lawv.

Kauj Ruam 2: Pib Txuas/soldering

• Ntxig cov hloov pauv hauv lub phaj (nws yooj yim dua rau nruab koj cov khoom ruaj khov tam sim no tab sis ntawm kev siv tes ua zoo li qhov no nws tsis tseem ceeb, koj tuaj yeem ua haujlwm tom qab)
• Kuv pom nws yooj yim dua los ua lub voj ntawm ib qho kawg ntawm diode ua ntej tso nws hla tus pin hloov raws li qhov no tau muab tso rau qhov chaw rau tus neeg muag khoom ua raws.
• Pib los ntawm kev siv lub diodes rau tus pin koj npaj siab siv rau koj kab (nws tsis muaj teeb meem dab tsi uas ntev li koj nyob zoo ib yam). Qhov no tuaj yeem pom hauv daim duab thib ob.
• Koj yuav pom yog tias koj piv cov duab thib peb rau txheej kab los ntawm cov lej uas lawv sib phim. Koj lub hom phiaj yog kom phim lub matrix raws nraim.
• Khoov lwm cov hlau lead los ntawm diodes thiab tso ib daim hlau hla lawv. Koj yuav tsum tau tshem tawm ib feem ntawm cov xaim kom muaj qhov khoob hauv qhov rwb thaiv tsev.
• Thaum cov kab tiav, rov ua qhov no nrog kab (tsis xav tau diodes rau kab)

NCO TSEG: Lub polarity ntawm diodes yog qhov tseem ceeb! Yog tias koj xaim lawv rov qab los ntawm qhov sib txawv ntawm koj lub rooj tsav xwm tswj hwm (zoo li kuv tau ua thaum xub thawj), nws yuav tsis ua haujlwm. Txoj hauv kev yooj yim tshaj plaws los txheeb xyuas qhov no yog nrog lub ntsuas hluav taws xob teeb tsa rau DC voltage. Txuas mus rau ib kab davhlau ya nyob twg thiab ib kab ntawv dav dav thiab saib seb qhov ntsuas yog tus lej zoo lossis tsis zoo. Siv qhov no qhia koj qhov kev txiav txim siab ntawm diode kev taw qhia.

Kauj Ruam 3: Txhim Kho Cov Teeb Kab

• Desolder cov ntsaws los ntawm lub rooj tswj hwm qhov twg matrix txuas nrog thiab hloov nrog xaim koj yuav siv los txuas rau koj lub ci ci tshiab cov tshuab hloov matrix.
• Siv phau ntawv qhia uas koj sau tawm ntawm tus pin mus rau kab twg/kab twg koj tau tsim hauv Kauj Ruam 1.

Kauj ruam 4: Ua tiav

• Nruab koj lub stabilizers rau hauv koj lub phaj (yog tias koj tsis tau ua hauv Kauj Ruam 2)
• Sib dhos cov rooj plaub thiab cov ntsia hlau ua ke siv koj cov M3 ntsia hlau.
• Nruab keycaps thiab koj ua tiav!
