Amblyopia (tub nkeeg qhov muag), teeb meem pom kev uas cuam tshuam kwv yees li 3% ntawm cov pejxeem, feem ntau yog kho los ntawm qhov muag yooj yim lossis atropine tee. Hmoov tsis zoo, cov txheej txheem ntawm kev kho mob ua rau lub qhov muag muaj zog ntev, tsis cuam tshuam lub sijhawm, tsis tso cai rau ob lub qhov muag (qhov tseeb yog lub paj hlwb hauv lub hlwb uas ua cov ntaub ntawv pom kev) ua haujlwm ua ke thiab ua ke. Tsis ntev los no kuv pom ib tsab xov xwm ntawm Wikipedia, uas qhia meej txog lwm txoj hauv kev kho, uas cov kua siv lead ua vaj huam sib luag tau muab tso rau ntawm lub qhov muag thiab thiab lawv qhov tshwm sim tau tsav los ntawm cov xov tooj cua. Cov kev tshawb fawb hauv daim ntawv kho mob no muaj kev cia siab heev, yog li kuv txiav txim siab "hloov kho" cov iav tsom iav zoo ib yam los ntawm 3D TV mus rau Kev Sib Hloov Kev Ua Phem Tsom iav.

Kho: Koj tuaj yeem pom cov iav tshiab dua ntawm no

Kauj ruam 1: Tsis lees paub

Kev siv cov cuab yeej zoo li no tuaj yeem ua rau qaug dab peg lossis lwm yam kev phom sij hauv qhov me me ntawm cov cuab yeej siv. Kev tsim cov cuab yeej zoo li no yuav tsum siv cov cuab yeej phom sij me ntsis thiab yuav ua rau muaj kev puas tsuaj lossis puas tsuaj rau vaj tse. Koj tsim thiab siv cov cuab yeej piav qhia ntawm koj tus kheej txoj kev pheej hmoo.

Txawm li cas los xij, muaj qee qhov chaw uas muaj kev pab kho mob zoo rau cov neeg uas muaj qhov muag tsis pom kev (tsawg kawg daim ntawv qhia WHO no qhia rau kuv). Hmoov zoo, hnub no $ 100 lub xov tooj ntawm tes muaj tib lub zog suav thiab daws teeb meem zoo li kev ua si PC muaj 10 xyoo dhau los, yog li kuv tus kheej ntseeg tias DIY cybernetic implants yuav muaj raws li kev kho mob rau ntau tus neeg hauv tsim teb chaws* sai dua li kev pab kho mob kom raug.

* qee lub nroog tom qab kev lag luam hauv North America muaj qee qhov "zoo" kev pov hwm kev kho mob tsim los ua rau tib neeg lub neej txom nyem ib yam nkaus !!!

Kauj Ruam 3: Siv Lub Tshuab Shutter 3D Tsom iav

Lub hauv paus ntawm cov kua siv lead ua vaj huam sib luag rau peb txoj haujlwm yog tsom iav 3D TV. Cov uas kuv siv raug nqi kuv $ 5 (lawv tau muaj ua ntej). Muaj ob peb hom iav tsom iav kom zoo, yog li nco ntsoov tias cov uas koj siv tau raug thaiv lub teeb pom kev zoo (koj tuaj yeem tshawb xyuas nws los ntawm kev muab cov lim polarizing lossis LCD tso rau ntawm lawv, nws yuav tsum ua haujlwm txawm tias iav tsis pom). Ceev faj tias ib qho ntawm cov yas txuas rau cov kua siv lead ua vaj huam sib luag tuaj yeem cuam tshuam lub teeb pom kev zoo. Thawj lub tsom iav kuv sim hloov kho tsis muaj lub lim polarizing pem hauv ntej teeb tsa rau hauv lawv (yuav tsum muaj 2 ntawm lawv hauv txhua lub vaj huam sib luag ua kua, raws li lawv tau tsim zoo ib yam li LCDs) thiab thaum yuam kom thaiv lub teeb, lawv tshwm xim liab, tsis dub, ntau ntxiv txog qhov no hauv Kauj Ruam kawg.

Active 3D TV tsom iav ib txwm ua haujlwm ntawm 60Hz, thaiv lub teeb sib npaug rau ob lub qhov muag. Lub qhov muag sab laug tau thaiv rau 8.333ms, thiab tom qab ntawd lub qhov muag sab xis raug thaiv rau 8.333ms, tom qab ntawd lub voj voog rov ua nws tus kheej. Qhov muag raug thaiv thaum qhov hluav taws xob tau thov rau LC vaj huam sib luag. Qhov hluav taws xob uas tsav LC panels yog sib npaug 9.2V (ncov-rau-ncov qhov siab tshaj 18.4V).

Kauj Ruam 4: Disassembly ntawm Active Shutter 3D Tsom iav

Siv tus ntsia hlau los tshem tawm cov ntsia hlau uas tuav tsom iav ua ke. Nws yuav yog lub tswv yim zoo los tso qee qhov kev tiv thaiv hla LC panels (Kuv yuav tsum tau ua tiav ua ntej kuv tshem cov ntsia hlau). Tom qab ntawd siv rab riam hluav taws xob (lossis lub thawv txiav) txiav qhov sib koom ntawm ob feem ntawm tus ncej. Tom qab ntawd siv lub tiaj tus ntsia hlau ntsia hlau los ntsaws qhib qhov sib koom ua ke. Prying nws qhib tej zaum yuav nyuaj me ntsis, tab sis nws yuav tsum muaj peev xwm ua tau (ceev faj kom tsis txhob puas cov iav iav!). Tom qab koj ua tiav txoj haujlwm ntawd, tshem tawm cov khoom siv hluav taws xob los ntawm tsom iav thiab desolder LC panels los ntawm PCB.

Kauj Ruam 5: Muab tsom iav ua ke

Cuab yeej 4 xov hlau rau LC vaj huam sib luag (lawv xav tau me ntsis ntev dua li cov uas tau qhia hauv daim duab). Siv cov kab xev thaiv kom ruaj ntseg daim kab xev nyias nyias uas los ntawm LC vaj huam sib luag thiab muab txuas rau cov xov hlau. Tom qab ntawd muab LC vaj huam sib luag rov qab rau hauv daim iav tsom iav, kho cov ntsia hlau. Koj tuaj yeem siv cov kua nplaum cyanoacrylate los koom nrog sab nraub qaum ntawm tus ncej. Roj teeb npog tsis xav tau thiab kuv tsis muab nws rov qab rau hauv nws qhov chaw.

Kauj Ruam 6: Programing ATtiny Microcontroller

Txuas ATtiny13 rau koj cov programmer uas koj nyiam, qhib qhov koj nyiam AVR dev cuab yeej thiab sau tsom iav.hex rau microcontroller FLASH nco. Khaws cov khoom siv fuse tsis raug (H: FF, L: 6A).

Kuv siv USBasp thiab AVRDUDE, yog li tom qab txuas VCC, GND, RESET, SCK, MISO, MOSI pins ntawm ATtiny13 rau programmer Kuv tsuas xav tau los ua ib qho lus txib yooj yim rau upload tsom iav.hex:

avrdude -c usbasp -p t13 -B 8 -U nyem: w: tsom iav.hex

Kuv tau pom tias Arduino cov laug cam tau nrov heev ntawm Cov Ntawv Qhia, yog li ntawm no yog qhov txuas rau kev qhia, uas piav qhia yuav hloov pauv Arduino rau tus programmer li cas. Koj tuaj yeem hla cov kauj ruam 5 txog 7 uas cuam tshuam nrog kev suav sau cov lej sau hauv C.

Kauj ruam 7: Soldering

Muab tag nrho cov khoom siv hluav taws xob tso rau hauv prefboard. Ntawm daim duab ntawm cov laug cam 1N4148 diode ploj lawm, Kuv txuas nws tom qab rau xaim-xiav xaim. Twisted xov hlau yuav tom qab txuas nrog cov roj teeb thiab tuav tau zoo nyob hauv qhov chaw los ntawm daim kab xev cais. Tsis txhob hnov qab txuas LC vaj huam sib luag xov rau PB0, PB1 thiab PB2 pins ntawm ATtiny13.

Kauj Ruam 8: Rooj Sib Tham Kawg

Siv daim kab xev cais kom cais sab hauv qab ntawm prefboard los ntawm lub cev ntawm cov neeg siv tsom iav. Txuas cov iav tsom iav ua ntej los ntawm daim kab xev nplaum uas koj xaiv.

Tom ntej no koj yuav tsum tau txuas 2 khawm hlwb (CR2025 lossis CR2032) rau lub cuab yeej. Hmoov tsis zoo thaum lawv tshiab, lawv qhov hluav taws xob tuaj yeem siab dua 3.3V. Ob ntawm cov hlwb tau txuas nrog ua ke, yog li txawm tias tom qab qhov hluav taws xob poob ntawm 1N4148 diode (tsawg tshaj li 0.7V), ATtiny tuaj yeem me dua nws qhov Kev Ua Haujlwm Siab Tshaj ntawm 6.0V. Kuv pom zoo kom tshem tawm cov roj teeb tshiab tag me ntsis, ua ntej muab tso rau hauv lub cuab yeej.

Cov cuab yeej siv kwv yees li 1 mA.

Kauj Ruam 9: Siv Qhov Tsom iav Qhov Kev Kawm Cuam Tshuam

Khawm txuas nrog PB3 hloov pauv cov khoom siv zaus (2.5Hz, 5.0Hz, 7.5Hz, 10.0Hz, 12.5Hz), thiab khawm txuas nrog PB4 hloov pauv ntev npaum li cas txhua lub qhov muag tau tshwm sim (L-10%: R-90%, L- 30%: R-70%, L-50%: R-50%, L-70%: R-30%, L-90%: R-10%). Tom qab koj teeb tsa, koj yuav tsum tau tos txog 10 vib nas this (10s ntawm tsis kov ib qho nyees khawm) kom lawv khaws cia hauv EEPROM thiab thauj khoom tom qab lub zog poob, ntawm lub cuab yeej tom ntej tso tawm. Nias ob lub nyees khawm tib lub sijhawm teeb tsa qhov txiaj ntsig.

Muaj tsawg kawg yog ib kis ntawm stereopsis rov ua tiav thaum saib cov khoom 3D. Yog tias koj xav siv Qhov Sib Txawv Sib Txawv Kev Kawm Tsom iav los saib cov ntaub ntawv 3D thaum hnav lwm khub ntawm cov iav zoo ib yam (tsuas yog tsis hloov pauv), koj yuav tsum tau txuas ib daim o yas meej rau sab nraub qaum ntawm lawv cov vaj huam sib luag LC, zoo li ib qho daim duab hauv Kauj Ruam 3 (lossis koj tuaj yeem siv daim kab xev scotch). Hauv qhov teeb tsa uas tsis hloov kho tsom iav zaum ze dua los tso saib. Los yog lwm txoj hauv kev koj tuaj yeem tso sab laug LC vaj huam sib luag tso rau sab xis thiab rov ua dua. Uas tig LC panels polarization, ntau dua ntawm qhov no hauv Kauj Ruam kawg. Txawm li cas los xij, ua li ntawd yuav ua rau koj tsis tuaj yeem saib koj cov zaub yam tsis muaj tsom iav qhov muag hloov pauv.

Kauj Ruam 10: Cov Haujlwm Zoo sib xws

Dichoptic e-phau ntawv nyeem: Thawj zaug rov ua dua ntawm kuv lub iav yuav tsum tau siv sab nrauv polarization lim. Kuv txuas nws tsuas yog rau sab xub ntiag ntawm sab xis LC vaj huam sib luag. Qhov ntawd tso cai rau kuv tso ob peb lwm yam lim dej polarization nyob rau sab saum toj ntawm e-ntawv zaub (uas tso tawm lub teeb uas tsis muaj lub teeb) thiab thaiv ib feem ntawm nplooj ntawv rau sab xis qhov muag tag (cov ntawv tom qab lim tam sim no flickering rau sab laug lub qhov muag, vim tam sim no yog polarized). Nws yuam kom kuv nyeem qhov thaiv nrog lub qhov muag sab laug thiab muab cov duab los ntawm ob lub qhov muag ua ke. Thiab muaj cov kev tshawb fawb hais, uas saib cov khoom dihoptic yog qhov muaj txiaj ntsig zoo rau cov neeg uas muaj amblyopia. Koj tuaj yeem ua qhov zoo sib xws nrog lwm cov lus qhia uas tso tawm lub teeb tsis zoo ib yam li CRTs. Tseem tseem muaj kev cia siab rau X-Ray qub tso tawm, lawv tuaj yeem siv tau ib zaug ntxiv!

Cybernetic monocle: Hmoov tsis zoo, kuv 3D TV lub polarization tau tig ntawm 90 degrees los ntawm polarization ntawm kuv lub PC saib. Kuv daws qhov teeb meem no los ntawm kev tso sab laug LC vaj huam sib luag tso rau ntawm txoj cai. Cov vaj huam sib luag hauv LC muaj 2 lub lim dej hloov pauv ntawm 90 degrees, yog li saib los ntawm lawv los ntawm lwm sab tig lub teeb pom kev zoo uas tau "txais" los ntawm LC vaj huam sib luag. Kuv kuj tau nce qhov hluav taws xob tsav LC panels rau 9V (ncov-rau-ncov qhov siab 18V) los ntawm kev siv H choj. Nws ua rau LC vaj huam sib luag ntau dua qhov muag thaum lub qhov muag. Tsis tas li kuv ntxiv LEDs uas nyem thaum lub sijhawm kaw, ntxiv "dig muag" lub qhov muag thiab tsis pub nws loj hlob mus rau qhov tsaus ntuj. Qhov "dig muag" cov txiaj ntsig yog qhov tshwj xeeb pom thaum kuv tso anaglyph 3D tsom iav nruab nrab ntawm kuv lub qhov muag LC vaj huam sib luag (xim lim dej nthuav tawm lub teeb). Raws li kuv tau hais ua ntej, saib cov ntaub ntawv 3D yuav zoo rau kev rov qab mloog zoo thiab kuv lub PCs saib tsis txhawb 3D thev naus laus zis uas tsis yog anaglyph, yog li kuv xav tias raug yuam kom qhia GZ3Doom (ViveDoom), tus qauv rau Doom classic ua si ua '90s. Nws tso cai rau koj siv ob hom iav anaglyph (ntsuab-magenta thiab liab-cyan), yog li koj tsis siv koj lub qhov muag ntau dhau los hnav cov xim lim dej ib yam.
