Txhim kho HP Scanjet5 network scanner nrog lub min-itx system thiab GNU/Linux txhawm rau kom ua tiav nrawm dua thiab ntxiv cov txiaj ntsig zoo xws li kev tswj hwm cov ntaub ntawv thiab khaws cov ntaub ntawv thiab server.

Kauj ruam 1: Npaj rau Hack

Lub tshuab luam ntawv tau tsim ua 2 ntu tseem ceeb: lub tshuab luam ntawv, uas yog tus qauv SCSI tiaj tiaj nrog 50 nplooj ntawv nplooj pub rau saum; thiab PC, uas yog AMD 486-dx 66Mhz system nrog IDE tsav, ntawm board scsi rau lub tshuab luam ntawv, thiab 2 ISA qhov qhib, ib qho rau network, ib qho rau cov vis dis aus thaum teeb meem (koj yuav tsum muab koj tus kheej daim npav video ISA). Rau cov uas xav khiav Linux ntawm cov khoom lag luam nrog me ntsis hauv txoj hauv kev ntawm cov yam ntxwv ntxiv, https://berklix.com/scanjet/ muaj qee cov ntaub ntawv zoo, thiab txawm tias ua tiav FreeBSD installer rau lub cuab yeej. Qhov no yog qhov uas kuv tau txais kuv pib hacking cov cuab yeej no. Kuv lub ntsiab lus txhawb rau kev hloov kho mini-itx yog tias lub zog hluav taws xob tawg lub tshuab hluav taws xob thiab ua rau ntau dhau ntawm PSU kom yooj yim kho tau, thiab kuv kuj muaj EPIA 800 lub rooj zaum zaum nyob ib puag ncig tos lub tsev.tools thiab ntu koj yuav xav tau:- soldering hlau- #1 thiab #2 phillips ntsia hlau tsav tsheb- rab koob ntswg qhov ntswg- xaim snips thiab stripper- IDE hard disk ntawm koj xaiv- 50-pin SCSI card (Kuv siv Tekram qub)- PCI txoj cai nce lub kaum, "A" sab, 5Volt. Kuv siv qhov siab 1.03 los ntawm risercardshop.com, tsuas yog Asmeskas lub vev xaib kuv tuaj yeem pom nrog qhov siab ntawd.- mini-itx, lossis me dua, mainboard. Kuv siv EPIA 800, muaj cua sov txaus thiab muaj lub zog txaus txaus.- 1U rackmount fais fab mov (135 Watt zoo li ua haujlwm)- 24 Volt 1.7 amp fais fab mov (Kuv siv 1.9 amp, me ntsis ntxiv tsis ua mob, thiab nco ntsoov nyeem cov ntsiab lus ntawm qhov kawg)- sacraficial AT/X PSU thiab molex rau 3 xaim kiv cua ntsaws rau qhov ntsaws ntxiv thiab xaim lossis txaus siab los txiav tus nqi kim PSU rau txuas cov xov hlau Feem ntau ntawm cov khoom no kuv tau tso ib ncig (Kuv yog me ntsis ntawm pob ntawv) yog li qhov haujlwm no tsuas raug nqi kuv li $ 30 tawm ntawm hnab tshos.

Kauj ruam 2: Tshem lub Scanner

Thov txim kuv tsis muaj lub koob yees duab ke thaum kuv ua qhov no feem ntau, tab sis nws yog cov khoom yooj yim tiag tiag yog li cov duab yuav tsuas yog nthuav tsis muaj txiaj ntsig ntawm qhov no. https://www.dvs1.informatik.tu-darmstadt.de/staff/haul/scanjet/Project_Network_Scanjet_Repair.html muaj qee cov duab zoo ntawm lub siab. Nyob tom qab ntawm lub tshuab luam ntawv muaj 2 tus ntsia hlau, cim nrog cov xub, kom tshem tawm thiab PC ib feem ntawm lub tshuab luam ntawv yuav swb tawm. Cov ntaub ntawv tsim muaj qhov ntxim nyiam latch/kev sib txhuam tsim uas ua rau nws coj txawv txawv kom swb tawm. Tsuas yog siv lub zog ruaj khov thiab rub nws me ntsis thiab nws yuav tawm tau yooj yim txaus. Nco ntsoov saib xyuas cov xov hlau, lub zog ntsaws plaub fab thiab lub xov tooj cua scsi yuav tsum tau muab tshem tawm kom tshem tawm lub tais kom tas. Tam sim no kev lom zem ib feem! tshem txhua yam los ntawm lub tais, yog, txhua yam! tej zaum koj tuaj yeem tso tus kiv cua tso rau hauv qhov chaw, tab sis tus so yuav tsum tau tawm, suav nrog kev faib nruab nrab ntawm thaj chaw PSU thiab thaj chaw tseem ceeb, nws yuav xav tau qee qhov kev txiav ua haujlwm. Thaum txhua yam tawm, koj yuav tsum tshem tawm thaiv qhov twg ISA network txuas rau sab nraub qaum, nws yuav yog txoj hauv kev ntawm ITX pawg thawj coj. Kuv twv koj tuaj yeem hloov kho nws, tab sis tshem nws zoo li yooj yim dua rau kuv. Koj tseem yuav xav tau tshem 2 ntawm lub rooj tsavxwm tseem ceeb. 2 yuav ua kab ntawm ITX, 2 yuav tsis. Kuv siv cov yas sawv ntsug los ntawm kuv lub thawv qub qhov chaw ntawm qhov tshem tawm. Yog tias chav nyob yuav tsum muaj sia nyob thauj khoom koj yuav xav coj mus rhaub ob peb qhov thiab ntxiv qhov sawv ntsug tiag tiag. cov khoom txaus kom tuaj yeem siv teh PSU lub qhov mouning, xav kom kuv muaj. Kuj kais qhov rau qhov kev sawv ntsug rau 24V PSU. (lub tshuab luam ntawv xav tau 24V, yog tias koj xav tsis thoob)

Kauj Ruam 3: Lub Sijhawm Rau Cov Kws Lij Choj

qhov no tuaj yeem nyuaj me ntsis, thiab kuv tsis tau sau ntau npaum li ntawd koj yuav tsum tau them nyiaj mloog mus rau koj cov khoom siv. PSU qub yog kuv qhov kev siv, nws muaj cov cim hluav taws xob cim rau ntawm lub rooj tsavxwm kom koj tuaj yeem ua raws cov xaim hluav taws xob ntsaws rau hauv pawg thawj coj saib seb koj xav tau dab tsi.

Kuv tseem tsis tau sim ua lub zog "vaj huam sib luag" nrog -12v, tsis xav coj mus txuas rau ntawm lub hwj chim atx kom txog thaum kuv paub lub kaw lus ua haujlwm, Kuv tuaj yeem ua qhov no ntxiv. nws zoo li yog tus qauv RS232, txawm hais tias kuv tuaj yeem lees paub tsis raug. Ok, thaiv cov hlua ua lub sijhawm. Ua ntej kuv clipped lub xwmfab scanner lub hwj chim ntsaws los ntawm PSU qub tom qab sau tseg ntawm cov xim muaj dab tsi voltages. Kuv clipped AT fais fab ntsaws rau ntsaws rau hauv 24V psu, yuav tsum tau txiav qee cov tab kom huv huv. Tom qab ntawd kuv txiav tus poj niam Molex tawm ntawm rooj plaub qub kiv cua passthrough lub zog txuas rau 5 volts nws xav tau los ntawm ATX ntawm n HDD molex. Thaum muag nws tag nrho kuv tau siv av los ntawm ATX PSU ib sab ntawm 5V thiab av los ntawm teh 24V ib sab ntawm 24V. Yog lawm, 2 PSU sib txawv ntawm ib lub cuab yeej, phem phem, Kuv paub. Thaum kawg, lawv faib lub zog hloov pauv thiab hauv av, thiab lawv ob leeg hloov khoom siv hluav taws xob, yog li txhua qhov txaus ntshai ntawm no yog qhov tsawg heev. Txog lub zog, Kuv tau txiav lub bracket tawm ntawm tus qub PSU sheild thiab tau teeb tsa thawj qhov ntsaws thiab hloov ntawm rooj plaub (saib daim duab thib ob). Kuv tau ntim lub hwj huam qaum rau ATX PSU thiab muab nws tso rau hauv rooj plaub ntsaws. Rau 24V's 120v sab kuv pom lub ntsaws los ntawm sab hauv lub ntsuas saib tuag (tsis nug) uas haum zoo, tsis muaj lub tswv yim dab tsi ntxiv uas yuav ua haujlwm, dua li siv txoj cai rau ntawm tus ncej. Rau tus kiv cua, tsis txhob siv txuas rau hauv qhov ntsaws qub (Kuv tau mob ntawm qhov muag ntawm qhov no), Kuv siv 3-tus pin kiv cua ntsaws rau 4 tus pin HDD molex adapter thiab tshem tus pin thiab yas "qhov tseem ceeb" yog li nws yuav ntsaws rau hauv tus kiv cua cov khoom ntsaws.

Kauj ruam 5: Kho System

Kuv xaiv Ubuntu, tab sis zoo nkauj npaum li cas linux distro yuav tsum ua haujlwm ib yam nkaus. Yuav tsum tau ntxiv "sg" rau /etc /modules txhawm rau kom muaj scsi scanner txhawb nqa ntawm khau raj, txhua yam ntxiv ua haujlwm tau zoo ntawm lub thawv! Txhim kho Sane los ua lub tshuab luam ntawv ua haujlwm, Samba rau cov ntaub ntawv siv, thiab Apache thiab "PHP Sane Frontend "rau cov ntaub ntawv yooj yim archival system. Kuv yuav tawm ntawm qhov teeb tsa ntawm cov haujlwm no raws li lawv txhua tus tau teev tseg zoo thiab tsom iav. Thaum kuv tau ncig los siv lub vaj huam sib luag thiab LCD, Kuv yuav siv tsab ntawv bash los ntawm https://berklix.com/scanjet / thiab tej zaum hloov nws me ntsis rau kev khaws cov ntaub ntawv hauv zos thiab xws li. Txog thaum ntawd, Kuv tab tom siv Genovation cov xov tooj tseem ceeb ntaus los ntawm qhov haujlwm qub uas yog lub ntsej muag loj, zoo li ghetto heev (tsis yog, kuv yuav tsis thaij nws: P). Kuv tau sau tsab ntawv ruby thiab tsab ntawv php (uas kuv yuav muab qhov chaw nres nkoj mus rau ruby thaum kuv kawm nws zoo dua, xa email yam tsis muaj MTA zoo li nyuaj rau ruby) txhawm rau ua haujlwm zoo ib yam li luam theej tawm rau hauv network sib koom lossis email chaw nyob. Cov ntawv ruby ua haujlwm ntawm cov keyboard, thiab php plhaub tsab ntawv ua haujlwm luam theej duab thiab xa email thiab smb cia. Kuv tau txuas cov ntawv sau, txaus siab!

Kauj Ruam 6: Xaus

Zoo, txhua qhov kuv zoo siab nrog qhov no. Qhov no yog qhov deb tshaj plaws txoj haujlwm kho vajtse uas kuv tau ua tas los thiab nws tau tawg! Kuv tau npaj meej rau kev ua ntau dua!

Yam kuv yuav ua txawv: - Ua ntej tshaj, Kuv yuav mus rau ib leeg hloov PSU dua li tuaj yeem muab txhua qhov sib txawv ntawm qhov kuv xav tau thiab txhawb txhua yam los ntawm nws. Ua qhov kev cai ATX ntsaws yuav tsis qis ntawm qhov ntsuas qhov mob, tab sis nws yuav ua kom huv dua thaum kawg. - siv sijhawm ntau nrog Ruby. nws damned haib haib scripting lang. siv me ntsis los qhwv koj lub taub hau ib puag ncig, tab sis cov syntax yog qhov huv dua li perl. - siv lub laptop disk, lossis khau raj los ntawm Compact Flash thiab muaj RAM tsav rau thaj chaw ua haujlwm. Qhov no txhais tau tias kev khaws cia yuav txwv, tab sis nws yuav nyob ze thiab ntsiag to me ntsis. Yog li nws puas tsim nyog nws? Hell yog! peb niaj hnub tshuaj xyuas cov pawg ntawm 40-50 nplooj ntawv rau PDF rau kev khaws cov ntawv digital, piv rau FreeBSD distro ntawm 486 nrog 8Meg ram qhov no yog tag nrho cov cuab yeej tshiab! pawg tau siv sijhawm ntev txog 20 feeb los hloov pauv thiab qee zaum khiav tawm ntawm RAM thiab tsuas yog ua tsis tiav, tam sim no txawm tias 50 nplooj ntawv siv sijhawm tsawg dua li ib feeb los ua PDF.
