Txoj haujlwm no siv CRT vim tias lawv yog cov ntxaij vab tshaus analog, thiab lawv kuj yooj yim hloov pauv mus rau oscilloscope. CRTs sab hauv cov neeg saib pom qub sib txawv ntawm cov tuam txhab mus rau tuam txhab, tab sis lawv txhua tus yuav muaj tib qhov qauv yooj yim. Yuav muaj cov hlua hluav taws xob ua kom pom nyob rau sab xub ntiag ntawm CRT, txuas/xov hlau ua rau lub rooj tsav xwm hauv Circuit Court, thiab hloov pauv hluav taws xob siab. Ceev faj! Thaum CRT tau siv hluav taws xob, lub tshuab hluav taws xob tsim tawm 1, 000-1, 500 volts, qhov no yuav tsis ua rau tuag taus (nws nyob ntawm qhov tam sim no), tab sis nws tseem tuaj yeem zap koj! CRT tau tsim kom cov khoom txaus ntshai tsis raug nthuav tawm, tab sis tseem siv kev nkag siab zoo. Tsim qhov no ntawm koj tus kheej txoj kev pheej hmoo! Ua ntej peb pib tsim lub Circuit Court, peb yuav tsum nrhiav qhov zoo, tsis zoo, thiab kab xev video rau CRT. Txhawm rau nrhiav cov xov hlau hauv av, siv lub ntsuas cua thiab teeb nws mus rau qhov txuas txuas mus. Tom qab ntawd, nrhiav cov hlau casing ntawm lub rooj tsav xwm hauv Circuit (tejzaum lub tsev hloov pauv), kov qhov kev sojntsuam mus rau qhov ntawd, thiab ntsuas txhua lub xovtooj ntawm lub teeb liab txhawm rau txheeb xyuas kev sib txuas. Cov xaim uas txuas nrog cov hlua hlau yog cov xaim av. Tam sim no lub zog thiab cov xov tooj vis dis aus nyuaj me ntsis. Cov xaim hluav taws xob tuaj yeem yog xim, lossis tuaj yeem muaj cov kab hluav taws xob loj ua rau nws. Kuv lub xov tooj hluav taws xob yog xaim xim av uas qhia hauv daim duab. Cov kab yeeb yaj kiab yuav muaj xim lossis nws yuav tsis yog. Koj tuaj yeem pom cov no los ntawm kev sim thiab ua yuam kev (tsis yog txoj hauv kev zoo los ua nws, tab sis kuv tau siv txoj kev ntawd thiab nws ua haujlwm), lossis los ntawm kev saib cov duab ntawm CRT. Yog tias koj muab lub zog rau CRT thiab koj hnov lub suab nrov tab sis lub vijtsam tsis pom kev, koj tau pom lub xov tooj hluav taws xob. Thaum koj tab tom tsim cov phiaj xwm hluav taws xob, cov xov hluav taws xob thiab cov xov hlau txuas tau txuas nrog rau +5v. Thaum koj tuaj yeem tau txais CRT npo teeb, koj npaj mus!

Nco tseg: Lwm CRTs yuav xav tau 12v, yog tias koj li CRT tsis tig txhua lub sijhawm thaum koj muab nws 5v, sim muab nws me ntsis siab dua 5v, tab sis tsis txhob tshaj 12v! Nco ntsoov tias CRT yuav tsis khiav ntawm 5v yog qhov no, vim tias yog tias koj li CRT yeej khiav ntawm 5v tab sis koj sim muab nws ntau dua 5v, koj tuaj yeem kib koj CRT! Yog tias koj pom tias koj CRT ua haujlwm ntawm 12v, koj yuav tsis xav tau tus tswj hluav taws xob thiab koj tuaj yeem txuas nws ncaj qha rau roj teeb.

Tseem ceeb: Ntawm kuv CRT thaum nws tau qhib thiab koj tshem lub ntsaws rau cov coils, koj yuav cia siab tias yuav muaj qhov me ntsis ci ntawm lub vijtsam vim tias lub teeb hluav taws xob tsis tau hloov pauv, tab sis CRT tig lub teeb hluav taws xob. Kuv xav tias nws ua qhov no yog qhov muaj kev nyab xeeb yog li koj tsis hlawv phosphor ntawm lub vijtsam los ntawm qhov nqaj tsuas yog nyob ntawd, tab sis peb tsis xav tau qhov no vim tias peb yuav siv ob lub coils txuas los ntawm pawg thawj coj. Ib txoj hauv kev koj tuaj yeem kho qhov teeb meem no yog tso me me resistor (10Ω) qhov twg cov kab rov tav yuav txuas rau lub rooj tsavxwm. Qhov "dag" no CRT rau hauv kev xav muaj lub nra nyob ntawd, yog li nws hloov qhov ci ci thiab pom qhov nqaj. Hauv cov kauj ruam tom ntej kuv yuav muab tus qauv tsim yuav tsim li cas. Yog tias txhua lub sijhawm koj tab tom tsim qhov no, koj pom lub teeb ci ntsa iab heev ntawm CRT npo, tua tag nrho lub zog rau CRT, yog tias lub tshuab hluav taws xob nyob qis qis ntawm lub vijtsam ntev dhau, phosphor tuaj yeem hlawv thiab rhuav tshem lub vijtsam.

Thaum koj tau sau tag nrho koj cov khoom, Kuv xav kom sim tawm lub Circuit Court ua ntej ntawm lub khob cij thiab tom qab ntawd tsim nws. Nco ntsoov tsim lub kauj "ua kom yuam kev" hais hauv kauj ruam 2 yog li koj tuaj yeem pom lub nqaj. Saib tag nrho cov duab ntawm kev tsim hluav taws xob zoo ua ntej koj tsim. Kuv soldered kuv lub Circuit Court ntawm cov laug cam sib txawv (ib lub rooj tsav xwm muaj tus tswj hluav taws xob, lwm tus muaj lub tshuab hluav taws xob daim duab peb sab, thiab lwm yam) Kuv kuj ntxiv kiv cua thiab lub rhaub dej kub rau kuv qhov ntsuas hluav taws xob vim tias nws kub. Yog tias koj xav hloov tus nqi ntawm koj lub tshuab hluav taws xob, koj tuaj yeem hloov pauv qhov hloov pauv ntawm lub pcb thiab nrhiav txoj hauv kev los hloov ntawm cov khoom siv hluav taws xob, lossis koj tuaj yeem ntxiv cov xov hlau ntawm pcb qhov twg koj yuav txuas lub tshuab hluav taws xob, thiab txuas lub tshuab hluav taws xob thiab cov xov hlau mus rau daim ntawv qhia zaub mov. Muaj peb lub tswv yim uas yuav hloov kho thaum koj siv oscilloscope (ob lub hwj chim thiab lub zog hloov pauv). Ib lub hwj chim hloov kho qhov oscillation zaus, lwm qhov hloov qhov dav ntawm daim duab peb sab yoj, thiab qhov hloov pauv thiab tawm ntawm CRT screen.

Tus "Khawv Koob" Tiv Thaiv: Hauv ib qho ntawm cov duab koj yuav pom tus tiv thaiv daim ntawv lo "Magic Resistor". Thaum kuv sim kuv daim duab peb sab lub tshuab hluav taws xob nws tsis ruaj khov, yog li qee qhov laj thawj coj txawv txawv kuv txiav txim siab muab 10KΩ resistor hla lwm 10KΩ resistor (saib daim duab) thiab oscillator ua haujlwm zoo kawg! Yog tias koj lub tshuab hluav taws xob daim duab peb sab tsis ua haujlwm, sim siv "Magic Resistor" thiab saib yog qhov ntawd pab tau. Tsis tas li, thaum kuv tsim, kuv yuav tsum sim ob peb yam sib txawv ntawm daim duab peb sab yoj oscillator tsim. Yog tias koj li tsis ua haujlwm thiab koj muaj qee qhov kev paub hluav taws xob, koj tuaj yeem sim qee qhov qauv sib txawv thiab saib seb lawv puas ua haujlwm.

Ceeb toom! Ntawm kuv thawj qhov kev sim, kuv tsis ntxiv lub zog hloov pauv, yog li thaum kuv mus sim lub tshuab hluav taws xob daim duab peb sab kuv txuas lub roj teeb rov qab thiab kib kuv oscillator. Tsis txhob cia qhov no tshwm sim rau koj! Thaum siv, CRT lub vijtsam yuav tsum zoo li nws ua hauv daim duab (yog tias koj txuas koj lub voos xwmfab tshuab hluav taws xob daim duab peb sab tso rau kab rov tav), yog tias nws tsis yog, muaj ob peb nqe lus nug koj tuaj yeem nug koj tus kheej:

1. Txheeb xyuas kom ntseeg tau tias koj tau txuas txhua yam kom raug. Puas yog cov roj teeb rov qab? Puas yog txhua yam tau txais lub zog?

2. Puas yog daim duab peb sab lub tshuab hluav taws xob ua haujlwm? Koj puas tuaj yeem hnov lub suab tsis tu ncua yog tias koj txuas tus neeg hais lus rau cov xov hluav taws xob?

3. Puas yog CRT coil "dag" Circuit ua haujlwm? Sim thiab qoj cov xov hlau me ntsis. Puas yog qhov screen qhib?

4. Puas yog qhov ntsuas hluav taws xob ua haujlwm?

5. Koj puas tuaj yeem tsoo qee yam?
