Tom qab siv lub laptop tau ntau tshaj kaum xyoo, kuv rov qab mus siv lub desktop computer ob peb lub hlis dhau los. Lub PC compact ntawm lub tuam txhab yav dhau los thiab lub monitor loj widescreen tau muab tso rau ntawm lub rooj sawv ntsug, nrog rau lub nas tsim nyog thiab lub IBM Model M uas kuv tau pab kuv tau ntau xyoo. Tam sim ntawd, qhov ergonomics ntawm kuv qhov chaw ua haujlwm tau zoo dua vim tias kuv tsis tas yuav khoov me ntsis kom pom lub vijtsam.
Cov khoos phis tawj desktop yav dhau los tau los ntawm lub sijhawm ua ntej. Kuv xav tias nws muaj cov neeg sib tw AMD uas sib tw nrog Pentium 4, thiab yog tias kuv nco qab zoo, nws lub cim xeeb 512 MB suav tias yog qhov tseem ceeb heev. Nyob rau sab nraub qaum, nws muaj ib pawg ntawm cov qhov (sockets) sib txawv kiag li ntawm kuv lub qhov (socket) tshiab, ib pawg ntawm cov chaw nres nkoj serial, ib qho chaw nres nkoj SCSI, thiab ib qho chaw nres nkoj luam ntawv sib luag. Hauv lub chassis, nws cov drives sib txawv tau txais kev pabcuam los ntawm ib pawg ntawm cov xov hlau ribbon. Nws txawm khav txog lub floppy drive. Qhov sib piv, cov xov hlau ntawm nws cov khoom ua tiav yog sib dua, thiab qhov loj ntawm lub connector yog me dua. Ntau lub USB plugs thiab ib lub network cable, nrog rau SATA rau nws cov disk drives. Lub sijhawm dav dav ntawm ntau qhov kev sib txuas tau dhau mus, thiab feem ntau ntawm peb yuav tau txais kev pab.
Qhov teeb meem nrog ntau lub cables yog tias lawv feem ntau kim heev thaum lub sijhawm ntawd, yog li kuv tseem xav tias lawv muaj qee yam nqi. Yog li txawm tias kuv lub SCSI tsav kawg lossis VGA saib xyuas tau tshem tawm cov kauj tuag no, kuv tseem dai ntawm lub cable, koj paub, tsuas yog thaum muaj xwm txheej. Muaj lub thawv bulging zais rau ntawm lub txee qhov twg, lossis yog tias koj nyob hauv kuv qhov chaw ua khoom hauv Milton Keynes, ib pawg ntawm cov thawv bulging. Ua ntej kuv ua tiav kev ntxuav, cia peb saib ze dua ntawm cov khoom cuav no, xav tias koj yuav tsis chim siab los ntawm kev coj lub tshuab txiav mus rau lwm cov cables zoo meej. Luam theej duab ib pawg, thiab feem ntau yog muab faib ua plaub pawg tseem ceeb. Parallel SCSI, VGA, lub tshuab luam ntawv sib luag, thiab vim tias qhov no yog SCART ntau-channel audiovisual cable sau hauv Tebchaws Europe.
Raws li koj xav tau los ntawm qhov sib txuas ua ke, SCSI cable siv daim ntawv ntawm ib pawg ntawm cov xov hlau, tab sis thaum koj saib ze rau sab hauv lub ntsaws, qhov xav tsis thoob yog tias tsis muaj kev tiv thaiv lossis khub sib ntswg ntawm cov xov hlau. Lub cable luam ntawv sib txuas muaj cov qauv zoo sib xws: nws tsuas yog qhov chaw nres nkoj 8-ntsis ntawm tus tswv tsev. Ntawm qhov tod tes, VGA thiab SCART cables muaj cov xov hlau coaxial shielded rau cov teeb liab video thiab qee cov xov hlau rau cov teeb liab tswj.
Thaum kuv xav txog yuav siv cov cables li cas, kuv thiaj li paub tias peb tau ua tiav ntau npaum li cas txij li thaum muaj ntau lub cable interfaces. USB tam sim no npog feem ntau ntawm cov khoom siv desktop uas ib zaug tau txais kev pabcuam los ntawm parallel SCSI, parallel, thiab serial ports, thiab yuav luag txhua qhov kev sib txuas audiovisual tau hloov mus rau HDMI sai sai. Cov serial interfaces ceev no muab cov ntaub ntawv siab dua nrog tsawg dua cov xov tooj liab.
Zoo li muaj ntau cov cables uas kuv tau pom txhua qhov chaw, thiab lawv tau dhau los ua tsis muaj txiaj ntsig. Tsis zoo li lwm yam kev hloov pauv thev naus laus zis, xws li los ntawm cov raj nqus tsev mus rau transistors, lawv qhov kev siv tau tsis tau txo qis nrog cov thev naus laus zis tshiab, yog li lawv lub neej ua haujlwm tsis tau dhau lawv lub neej ua haujlwm. Ntawm qhov tsis sib xws, thaum lawv cov thev naus laus zis mus txog nws qhov siab tshaj plaws, lawv tam sim ntawd dhau los ua e-pov tseg, qhov twg peb tuaj yeem nrhiav qhov chaw ntawm lawv tus nqi attribution. Yog tias koj muaj ib pawg ntawm SCSI cables qhov twg, koj puas tuav lawv vim koj xav tias koj yuav xav tau lawv dua ib hnub twg?
Hlawv cov xov hlau kom rov qab tau tooj liab, 2018, Accra, Ghana. Muntaka Chasant [CC BY-SA 4.0]. Yog li peb yuav tsum ua li cas? Lawv puas siv tau rau lwm lub hom phiaj? Txawm li cas los xij, leej twg siv cov xov hlau 40-txoj kev lossis ntau cov xov hlau coaxial tsis zoo hnub no? Kuv xav hnov ​​koj lub tswv yim hauv cov lus.
Tib lub sijhawm, kuv muaj ntau cov xov hlau uas yuav tsum tau daws, thiab qhov no yog qhov teeb meem. Cov tooj liab uas lawv muaj muaj nqis, tab sis feem ntau, lawv cov khoom siv rwb thaiv tsev yog PVC. Kev siv rov qab yuav muaj teeb meem. Yog tias qhov ua haujlwm kub hnyiab tsawg, nws yuav tso cov tshuaj lom tawm. Tau ntau xyoo, muaj ntau qhov kev txaj muag uas cuam tshuam txog kev xa tawm cov khib nyiab hluav taws xob los ntawm cov tebchaws tsim kho mus rau cov tebchaws tsim kho. Cov khib nyiab tau hlawv rau hauv qhov qhib kom rho tawm cov hlau. Txawm hais tias muaj kev ntsuas tau ua los xaus qhov kev coj ua no, tseem muaj kev txhawj xeeb txog cov xov hlau raug pov tseg kom raug cai.
Ntawm no, kuv lub nroog muaj cov chaw ua haujlwm rov ua dua tshiab, thiab tom qab ntawd xa cov khoom siv rov ua dua tshiab uas tau xaiv tseg mus rau cov tuam txhab tshwj xeeb rov ua dua tshiab. Rau cov xov hlau PVC-coated, lawv raug txiav kom cais cov tooj liab ntawm cov yas, thiab tom qab ntawd cov yas raug rhuav tshem los tsim cov khoom siv hydrocarbon raw rau kev lag luam tshuaj lom neeg.
Hauv kuv qhov chaw hacking, peb yuav tuav ib pawg neeg ua haujlwm los txo cov cable pile kom tsawg li tsawg tau. Peb tau ntsib dhau los ntawm ib lub sijhawm tsis paub txog nws, txawm tias Brian Benchoff hu ua Hackaday ob peb xyoos dhau los. Inevitably ob peb xyoos tom qab, peb yuav pom SCSI peripheral thiab khuv xim pov tseg cov SCSI cables, tab sis xav txog qhov chaw peb yuav tau txais, kuv xav tias peb yuav pheej hmoo. Lo lus nug yog, koj puas yuav?
Koj yuav tsum tau qhib kuv lub hnab tes 30 xyoo ntawm kuv txhais tes txias tuag ... Kuv tau ua haujlwm hauv AV, POS, tuam txhab thiab kev noj qab haus huv IT thiab kuv tau txais cable ... (nrog Ram, ISA modem lossis 2): P
"Yog li txawm tias kuv lub SCSI drive lossis VGA monitor kawg tau tshem tawm cov kauj tuag no, kuv tseem dai rau ntawm lub cable, koj paub, tsuas yog thaum muaj xwm txheej."
Kuv tau pom qee qhov nrog HDMI / DisplayPort, tab sis txawm tias cov servers tshiab tseem muaj VGA (EG, HP DL380 Gen10). Tsis muaj leej twg xav pov tseg (lub adapter peb yuav) tag nrho cov KVMs uas tseem nyob hauv chav server. (Lossis yog tias koj tsis muaj peev xwm them taus KVM, koj tuaj yeem siv "zaub tso saib nyob ib sab ntawm lub khib nrog lub cable ntev heev"). Txawm li cas los xij, USB tau hloov chaw nres nkoj PS2 tiav lawm, yog li kuv xav tias peb yuav tshem tawm VGA thaum kawg.
Yog tias tus nqi ntawm HDMI adapter tsawg dua $ 5 microcontroller uas koj xav siv nws, ces kuv lees tias VGA tsis siv lawm.
Koj tuaj yeem yuav ib qho ntawm AliExpress rau $ 3.75 nrog kev xa khoom dawb. Kuv xav tias nws yog lub sijhawm rau feem ntau ntawm cov neeg txav mus. https://www.aliexpress.com/item/32947446707.html

Kuv sim txuas HDMI rau kuv lub LCD ntawm lub console uas FreeNAS tsim, tab sis nws tsis ua haujlwm zoo. Yuav tsum tau yuav ib txoj hlua VGA los ntawm lub khw muag khoom hauv zos rau $ 5, thiab tam sim no kuv tuaj yeem mus dua. Ha ha
Cov khoos phis tawj DIY xws li Arduino khoos phis tawj thiab FPGA cov laug cam tseem siv VGA, vim tias ob peb lub resistors tuaj yeem tsim cov teeb liab analog video zoo. Txawm li cas los xij, kuv yuav tsum xav paub seb DVI-A puas sib xws nrog cov cables, lossis tsawg kawg yooj yim li ntawd?
Cov xov hlau VGA tseem siv tau rau kev txuas cov projectors rau cov laptops, vim tias cov xov hlau HDMI ntev tsis yooj yim puas - lawv ua haujlwm lossis tsis ua haujlwm. Lub teeb liab VGA zoo li tsis meej me ntsis, tab sis tsis muaj leej twg yuav pom.
Kuv tau yuav ntau lub EMI VGA extenders ntawm lub khw muag khoom siv tes thaum kawg lub lim tiam, txhua lub rau $ 0.50. Tab sis kuv tsis tau pom lawv cov ntaub ntawv los ntawm kev tshawb nrhiav hauv Is Taws Nem.
"Kev muab ua ke" feem ntau tsis muaj txiaj ntsig. Tab sis cais lawv, thiab koj yuav muaj ntau cov xov hlau "dawb". Cov xov hlau khov kho yog qhov zoo tagnrho rau kev ua cov breadboards lossis cov qauv prototypes tas mus li. Cov cores stranded tsis tshua muaj, thiab feem ntau zoo dua li cov cores khov kho. Nws yog qhov tsim nyog heev rau kev txuas cov kev sib txuas ua ke.
Koj tuaj yeem khi ob peb txoj xov xim sib xyaw ua ke, ntswj lawv ua ib lub voj voog, thiab dov cov kawg kom ua ib lub voj voog zoo li paj. Kwv yees li 4 xyoos dhau los, kuv tau txais ib
Tuaj ntawm no rau qhov no. Nws yog qhov pheej yig tshaj plaws ntawm ntau cov xov hlau sib txuas xim sib txawv. Kuv tsis xav yuav 40 lub spools ntawm cov xim sib txawv, tab sis qee zaum kuv yuav tsum npaj ntau xim rau ib qho project, thiab tom qab ntawd kuv yuav nrhiav ib tus neeg laus no thiab tev nws tawm.
Thaum koj pom ib lub SCSI drive qub, qhov teeb meem yog seb koj lub system puas muaj ib lub controller ua haujlwm, software uas txhawb nqa lub controller ntawd, thiab lub cable kom raug los txuas lawv - qhov kawg SCSI no mus rau lwm qhov kawg SCSI... .
Ob peb xyoos dhau los, thaum kuv pom ib lub hard drive qub uas kuv tej zaum yuav tsis tau siv ntau tshaj 10 xyoo, kuv lub hard drive puas lawm. Kuv siv ib teev lossis ob teev nrhiav cov khoom siv los txuas rau nws, koj paub, tsuas yog xav saib seb muaj dab tsi nyob hauv nws. Tom qab ntawd kuv paub tias kuv tsis tau siv nws ua dab tsi tau ntau xyoo, thiab cov lus teb yog "Kuv tsis quav ntsej"
Kuv pom qee cov xov hlau qub thiab cov chaw zoo ntawm cov xov hlau (yog, kuv paub tias lawv yog ua los ntawm cov khoom siv no, tab sis tsis yog txhua "xov hlau" zoo ib yam).
Cov xov hlau hauv SCSI cable hauv daim duab no muaj txiaj ntsig zoo heev - nws yuav yog tus neeg hlau tooj liab tiag tiag nrog kev rwb thaiv tsev zoo hauv ntau xim - tsim nyog heev rau kev ua tej yam, thiab zoo dua li cov ntawv ci tooj liab ntawm nylon core, zoo li niaj hnub no Zoo li ntau cov xov hlau.
Txawm li ntawd los, koj xav tau ntau npaum li cas? Tsis ntev los no, kuv tau dhau los ntawm kuv lub thawv cable thiab thaum kawg tau txais ob peb lub xov hlau zoo sib txuas (uas tuaj yeem sib cais ua cov xov hlau ib leeg tom qab tshem lub hnab). Tus so yeej tsis haum rau kev kho dua tshiab. Qhov ntau ntawm qhov chaw tom qab tshem tawm 3, 4, lossis 5 lub thawv nyiaj puv nrog cov xov hlau yog qhov rov qab zoo.
"Ces kuv mam li nco dheev tias kuv tsis tau siv nws ua dab tsi tau ntau xyoo, thiab cov lus teb yog qhov tseeb tias 'Kuv tsis quav ntsej'." "
Kuv muaj li rau lub IDE drives tos kuv nrhiav lawv. Kuv ntseeg tias muaj qee cov duab digital (qee cov) uas tsim nyog rov qab tau.
Txawm li cas los xij, ntau yam khoom siv tshwj xeeb (xws li cov khoom siv kho mob) feem ntau xav tau cov khoom qub kom khiav tau. Kwv yees li 15 xyoo dhau los, kuv tus neeg paub tau nug kuv tias nws puas paub tias nws yuav tau txais 20 Meg hard drive qhov twg. (IIRC, nws xav tau ST-225)
Muaj ntau lub cuab yeej synthesizer qub uas siv SCSI. RaSCSI zoo heev, tab sis kom nws ua haujlwm tau, kuv xav tau _yuav_ ib txoj hlua SCSI. 2018!
(Qhov tseeb, lawv tsis yog qhov phem. Lawv muaj nyob rau ntawm lub khw online hauv zos rau $ 10 thiab yuav xa tuaj rau ob peb hnub. Tsis muaj laj thawj yuav tsum khaws cov xov hlau.)
Kuv tseem muaj qee cov ST-225 thiab ST-251 (40MB!) nyob hauv 286 qub. Lub suab ntawm lawv tig ua rau kuv nco txog yav dhau los.
Tom qab kuv khaws kuv cov khoom SCSI qub rau 1 txog 2 xyoos, thaum kawg kuv muab pov tseg, tab sis yeej tsis tau siv nws tiag tiag, thiab tom qab ntawd tsis yog 2 lub hlis tom qab, ib tug neeg tau muab daim npav SCSI thiab lub hard drive A2000 rau kuv.
Nov yog kuv zaj dab neeg. Txhua zaus uas kuv kov yeej kuv tus kheej thiab muab pov tseg yam uas kuv tau khaws cia rau ntau xyoo (lossis ntau xyoo) hauv 6 lub hlis, thaum kawg kuv pom nws siv tau thiab tsis muaj nws lawm.
Kuv muab lub Zip drive kawg pov rau hauv lub thoob khib nyiab, thiab hnub tom qab kuv tau txais kev thov kom theej cov ntaub ntawv los ntawm lub thawv puv nrog Zip disks. Ua ib txoj haujlwm them nyiaj, kuv tau los ua tus neeg dhia dej hauv kuv lub thoob khib nyiab.
Cov keyboard thiab nas tau dhau los ua wireless, ib yam li Is Taws Nem, thiab koj yuav pom ib lub system uas tsuas muaj cov video thiab cov xov hluav taws xob xwb! (Hauv Mac, cov no tej zaum yuav yog tib lub cable)
Ua ntej tiam 3, M.2 hard drives yog tus qauv teeb tsa ntawm lub motherboard, thiab lawv tau ntxig zoo li daim npav wifi hauv lub laptop. Lwm txoj hlua tsis muaj lawm.
DisplayPort yog qhov chaw siv rau kev yees duab. Thunderbolt tab tom ntes tau. Koj tuaj yeem xaiv xa cov ntaub ntawv qhov chaw nres nkoj tso saib lossis PCIe, thiab nruab rau lub vijtsam lossis GPU sab nraud.
Ib qho me ntsis tawm ntawm lub ncauj lus: Kuv muaj qee qhov luv nqi rau cov qauv Lenovo Tiny qub, M72e M92p M93p M900 M700, thiab lwm yam. Yog tias koj xav mus vwm, P320 P300 muaj daim npav PCIe tiag tiag nrog 4x video tso zis (+2 onboard los ntawm iGPU)
Kwv yees li ntawm 7"x7"x1.5" thiab siv cov processors desktop tiag tiag. Zoo kawg nkaus! (Kuv paub tias lawv yog cov processors tsawg tsawg uas tsis tshua muaj zog thaum xub thawj, tab sis kuv ntseeg tias cov processors ib txwm tuaj yeem ua haujlwm, tej zaum siv throttle stop lossis Intel XTU los txo qhov voltage. Kuv lub 4570t low-power chip siv 40 watts ntawm turbocharger, txawm tias nws yog me ntsis ntawm 35w chip. Yog li kuv nce turbo tdp mus rau 40 thiab txo nws los ntawm 60 millivolts, ua kom nws yog 36-watt turbo nce Pressure. Yog tias koj xav tau lub kaw lus pheej yig, kuv ntseeg tias koj tuaj yeem nce 51w desktop chip mus rau 40-45w, lossis siv lub non-turbo low-speed chip)
Tsis yog...tsis yog txhua lub keyboards thiab nas yog wireless. Yog lawm, muaj cov keyboards thiab nas wireless rau cov neeg uas xav tau lawv...tab sis ntau lub yog wired, thiab nyob ntawm seb daim ntawv thov, wired keyboards/mouses zoo dua ntau txoj kev.
Tsis yog vim lawv txuas nrog USB lawm, vim nws txwv qhov refresh rate rau 125 Hz, thiab koj tsis tuaj yeem ua n-key rollover lawm. Qhov laj thawj yog vim PS/2 xa cov code on/off, thaum USB hloov kho tus nqi key uas hloov pauv, thiab tsuas muaj rau tus yuam sij uas tuaj yeem hloov kho rau ib lub thav duab.
Qhov sib piv, qhov chaw nres nkoj PS/2 yog qhov chaw nres nkoj serial ua haujlwm ntawm tus nqi "refresh" ntawm kwv yees li 1500 Hz, vim qhov no yog lub sijhawm ntev npaum li cas rau kev hloov kho code kom dhau mus. Tus tswv tsev khaws cia cov nyees khawm twg raug nias lossis tsis raug nias.
Yog li ntawd, txhua lub keyboards (thiab nas) niaj hnub no raug qeeb qeeb los ntawm USB thiab tsis muaj qhov zoo dua li cov qauv wireless zoo.
Rau kuv, qhov zoo tshaj plaws ntawm cov keyboard thiab nas uas muaj xov hlau yog tias tsis muaj roj teeb los rov them lossis hloov.
Kuv tus nas uas muaj xov hlau qee zaum mob thiab plam tawm ntawm sab nraub qaum ntawm lub tais keyboard. Tab sis qhov no yeej zoo dua li cia kuv tus ntxhais coj tus nas uas tsis muaj xov hlau, vim nws poob nws!
Rau tus nas, qhov sib txawv tsis ntau, vim tias txoj kev uas lub khoos phis tawj nyeem tus nas PS / 2 txawv me ntsis. Nws xa cov kev cuam tshuam ntawm qhov zaus ntawm 200 Hz, yog li tus nas USB wired tsis qeeb heev, thiab vim yog cov chav kawm HID sib txawv, nws tuaj yeem teeb tsa rau qhov refresh rate ntawm 1000 Hz.
Kuv tau hloov mus siv lub nas wireless thaum xyoo 1990s lig, lossis tej zaum nws tseem ntxov heev. Vim tias kuv lub roj teeb nas tuag lawm, kuv tau foom thiab ua yuam kev rau ntawm cov yuam sij luv luv rau ob peb xyoos. Tom qab kuv loj hlob tuaj, kuv txiav tawm qhov ntawd. Tam sim no kuv tsuas yog siv lub nas wireless ntawm cov khoom siv portable xws li xov tooj ntawm tes lossis ntsiav tshuaj.
