Hauv tsev kuv siv ob lub khoos phis tawj txuas ua ke rau ib tus saib, ib lub keyboard thiab ib tus nas hla KVM hloov. Ntawm lub rooj kuv tseem muaj lub tshuab luam ntawv, uas kuv faib nruab nrab ntawm ob lub khoos phis tawj. Hmoov tsis zoo KVM hloov tsis txhawb nqa USB ntau ntxiv thiab txhua lub sijhawm thaum kuv luam tawm, kuv yuav tsum rov txuas lub tshuab luam ntawv ua si nrog USB txuas. Txhawm rau ua kuv lub neej yooj yim Kuv txiav txim siab yuav qee qhov hloov pauv USB pheej yig. Kuv pom qhov no hauv Aliexpress. Kuv tau txaus siab txheeb xyuas dab tsi yog sab hauv thiab kuv pom tias nws yog txhua yam tshuab. Qhov ntawd txhais tau tias nws yog ob txoj kev - tuaj yeem siv rau lub hom phiaj sib txawv:
- Qhov uas kuv xav tau - txuas ib lub tshuab luam ntawv rau ob lub khoos phis tawj
- Txhawm rau hloov ntawm ob lub cuab yeej USB txuas nrog ib lub khoos phis tawj. Hauv qhov no kuj yuav tsum tau siv USB tshwj xeeb tshwj xeeb - ob tog txiv neej rau txiv neej txuas hom. Qhov kev siv no tuaj yeem tso cai piv txwv ob Arduinos txuas nrog lub khoos phis tawj thiab sib txuas nrawm lossis ob daim npav USB sab nraud….etc.
Nws tuaj yeem pom ntawm daim duab uas kev sib pauv ntawm ob lub USB B-hom chaw nres nkoj tau ua los ntawm kev siv ob txoj haujlwm yooj yim hloov. Muaj ib daim duab qhia qhov chaw nres nkoj twg ua haujlwm thaum hloov pauv tau nias thiab tsis yog.
Txhawm rau hloov pauv me ntsis yooj yim dua rau siv Kuv txiav txim siab teeb tsa ob lub LED qhia (rau thawj zaug siv, uas ntawm ob lub khoos phis tawj yog ON tam sim no thiab USB ntaus ntawv twg txuas nrog lub khoos phis tawj thib ob ntawm kev siv)
Cov lus qhia no piav qhia luv luv tias qhov no tuaj yeem ua tau li cas.
Kauj ruam 1: Dissembling thiab tshuaj xyuas ntawm USB Hloov
Hauv qab ntawm lub thawv tuaj yeem pom ob tus ntsia hlau. Thaum tshem rooj plaub tuaj yeem qhib tau. Txheeb xyuas lub rooj tsavxwm Kuv pom tias cov khoom siv thiab cov xov hlau hauv av kuj tseem sib txawv - qhov ntawd yog qhov kuv xav tau.
Kauj Ruam 2: Qhov Yuav Tsum Tau
- ob lub LED - Kuv xaiv 5mm nrog cov xim sib txawv - kom paub qhov txawv ntawm qhov tsaus ntuj
- ib qho 330 Ohm rau 1.5 kOhm resistor
- qee cov xov hluav taws xob
- ib daim ntawm thermo-shrinking tube.
- ob tus tuav LED (xaiv tau)
Kauj ruam 3: Mounting ntawm LEDs
Kuv drilled ob qhov rau diodes nyob rau sab saum toj ntawm rooj plaub. Lub qhov tau ua tiav hauv cov haujlwm zoo li no uas cov teeb tsa LED tau nyob hauv qhov chaw pub dawb ntawm USB qhov nyob thiab qhov hloov pauv. Kuv tau teeb tsa cov tuav LED thiab tso lub LED; nyob ntawd. Txhawm rau txhim kho ces kuv tau siv rab phom kub kub.
Kauj Ruam 4: Kev Sib Txuas Hluav Taws Xob - Kev Muag Khoom
Kuv txuas cov LED; s cathodes ua ke. Ua qhov sib koom ua ke kuv tau siv lub zog tiv thaiv nrog cov xaim xaim hluav taws xob (xiav ib qho) ntawm lwm lub davhlau ya nyob twg. Kuv muab lub raj thetmo-shrinking hla tus resistor thiab rhaub nws. Ntawm LED tus anode pins kuv tau siv ob lub xov hlau liab. Cov xov hlau liab no kuv tau muab txuas ncaj qha rau cov khoom siv ntawm qhov sib txuas USB sib txuas (saib daim duab nyob qhov twg). Kuv tau xaim xaim xaim (tsis zoo) los ntawm lub qhov uas twb muaj lawm ntawm PCB, tso lub rooj tsavxwm rau ntawm nws txoj haujlwm raug thiab muab cov xaim xaim txuas rau GND tus pin ntawm tus poj niam A-hom USB qhov (socket). Tom qab ntawd kuv kaw rooj plaub thiab kho nws dua nrog cov ntsia hlau.
Kauj ruam 5: Npaj
Kuv txuas qhov hloov mus rau kuv lub tshuab luam ntawv thiab khoos phis tawj los ntawm kev siv luv USB B hom cable. Kuv luam tawm nplooj ntawv xeem yam tsis muaj teeb meem. Txhua yam ua haujlwm tau zoo thiab kuv tsis tas yuav khawb hauv cov kab sib txuas los xyuas seb kab ntawv twg los qhov twg.
Thiab qhov zoo yog qhov zoo dua - Kuv nyiam teeb xim thaum tsaus ntuj, thaum kuv zaum ntawm kuv lub rooj feem ntau.
Ua tsaug rau koj nyeem.
