Realtime Video Effects Nrog Suab Reactive Psychedelic Visuals. Tshawb nrhiav hauv is taws nem koj tuaj yeem pom ntau lub suab siv hluav taws xob tab sis analogvideo effect circuits tsis tshua muaj. Vim li cas?

Puas muaj kev txaus siab? Visualist yog qhov haujlwm tawm xyoo 2011 tab sis kuv tsis tau tshaj tawm qhov no ntawm Instructables, txog tam sim no. Lub sijhawm tiag tiag cov cuab yeej yees duab tsis raug rau VJ's, DJ's thiab lwm tus kws ua yeeb yam zoo rau kev ua yeeb yam.

Cov vis dis aus tau tshaj tawm thawj zaug hauv German Funkschau cov ntawv xov xwm ntev dhau los. Lub Circuit Court yog pheej yig. MC1377P tsuas yog ib feem uas tsis yog ib txwm muaj. Suab- thiab video Circuit tuaj yeem tsim rau kwv yees li 60 daus las.

Saib xyuas, tsuas yog cov neeg uas muaj txuj ci hluav taws xob txaus thiab nrog oscilloscope tuaj yeem coj txoj haujlwm no mus rau qhov kawg. Thov txim.

Kauj ruam 1: Yees duab

Kauj Ruam 2: Thaiv Daim Duab Video Effects Controller

Thawj daim duab qhia txog daim duab thaiv ntawm pawg thawj coj saib video; ib yam ntawm daim duab ntws. Hauv lub voj voos no cov vis dis aus xim tso tawm tau ua rau hauv b/w teeb liab los ntawm kev txiav tawm cov xim tawg uas siv lub ntsej muag lim (10.7Mhz). Nws tsis zoo tag nrho tab sis nws txaus.

Lub teeb liab tau faib ua 2 txoj kev:

1- Via tus sib piv IC1a qhov sib txuas ua ke tau dhau mus rau oscillator IC4c/d (31250khz) los ua ib nrab ib txwm PAL-sync-sib xyaw rau IC9, "nto moo" MC1377P RGB rau PAL/NTSC encoder.

2- Txoj hauv kev los ntawm xya tus neeg sib piv IC1 thiab IC2. With rau tus tiv thaiv nruab nrab ntawm IC3a/b peb tuaj yeem tswj hwm qhov siab thiab qis dua thiab qhov pib rau txhua qhov teeb pom kev zoo nyob nruab nrab. Hauv lwm lo lus, lub teeb liab yuav "hlais" mus rau 7 qib kev ci ntsa iab. Txhua qib yuav tsim xim tawm ntawm ntau qhov kev sib xyaw ua ke xaiv los ntawm IC6 thiab IC7. Cov sib piv potmeters zoo rau sim nrog. Hauv video koj tuaj yeem pom cov txiaj ntsig zoo.

Qhov tseeb yog lub tshuab hluav taws xob xim "cuav". Tom qab tus neeg sib piv lub teeb liab dhau los ntawm tus lej nkag ua ntej IC5 uas ua rau 3-ntsis-lo lus. IC6 thiab IC7 (1 ntawm 4 qhov hloov pauv sib xws) tab tom hloov xim. 2-ntsis tswj lub teeb liab yog tsim los ntawm IC10 thiab IC4a/b.

Nias lub pob "xaiv xim" luv luv ua rau hloov xim; tuav lub pob kom ua qhov hloov xim tas li. Cov teebmeem ntau yog tsim los ntawm RGB inverter keyboards; lawv ntxeev cov xim txheej.

Kauj Ruam 3: Soundboard

Daim duab thaiv ntawm lub rooj tsav xwm suab qhia pom qhov hloov pauv ntawm lub microphone built-in thiab cov kab nkag. Tom qab ntawd los txog lub ntim ntim tsis siv neeg. Qhov thib peb yog lim rau ntses bass thaj tsam, nruab nrab thiab lub suab nrov. Kawg yog cov tsav tsheb LED rau Lub Teeb Pom Kev Tiv Thaiv. Lawv tswj lub RGB xim saturation hauv cov zis video teeb liab.

Daim duab thib ob qhia txog lub suab hluav taws xob. Qhov duab thib peb yog daim duab ntawm lub suab suab ua los ntawm ib lub rooj tsav nkoj.

Daim duab plaub qhia txog 3 qhov ntsuas hluav taws xob nyob rau sab saum toj thiab tus choj LED/LDR nyob hauv qab.

Hloov peb 560ohm resistors los ntawm 470ohm potentiometers ntawm daim vis dis aus, thiab sib luag rau qhov no lub teeb pom kev tiv thaiv ua rau cov xim ntawm VISUALIST reacts ntawm lub suab ntawm lub microphone lossis lub suab kab-nkag. Yog li, peb tau txais tes- thiab tswj suab ua ke. Lub suab hluav taws xob yog Elektor tsim thiab yog lub cev xim LED. Kev tswj ntim tsis siv neeg ua rau kev tswj tes tsis tsim nyog los ntawm kev hloov pauv ib puag ncig lub suab. Koj tuaj yeem pom cov ntawv luam tawm Circuit thiab teeb tsa ntawm Elektor tsim hauv daim duab tsib thiab rau.

Qhov tseem ceeb yog kev siv lub teeb pom kev tiv thaiv kab mob hauv daim vis dis aus. Lawv sib koom ua suab hauv cov vis dis aus.

Kauj Ruam 4: Tsim Videoboard

Daim duab ib qho qhia txog lub rooj tsav xwm luam tawm. Daim duab ob qhia txog kev tso cov khoom tso rau ntawm lub rooj tsavxwm.

Saib xyuas; ua kom zoo sib txuas. Ua ntej txhua txoj hlua hlau; tom qab qhov chaw IC pins. Ua haujlwm huv. Daim duab peb qhia cov cim oscilloscope rau kev ntsuas ntawm cov ntsiab lus ntsuas. Daim duab plaub qhia txog cov khoom ntawm daim vis dis aus. Lub teeb liab cabling ntawm cov keyboards, potmeters thiab audio/video board yuav tsum yog qhov zoo. Kev sib txuas feem ntau yog ua tiav nrog cov xov hlau coax.

Txhawm rau ua kom tiav cov vis dis aus txuas ntxiv yuav tsum muaj oscilloscope. Ib daim ntawv teev cov xeem thiab cov cim koj tuaj yeem pom hauv daim duab peb.

Kauj ruam 5: Lay-out ntawm lub Controllerbox

Kuv tsim Visualist hauv lub thawv microphone. Tsis tas li lub ntsuas me me yog tsim-hauv. Koj muaj txoj hauv kev tso cov nyees khawm thiab cov lauj kaub hauv qhov uas zoo rau koj. Cov tswv yim ntawm Visualist tuaj yeem los ntawm PAL lossis NTSC lub koob yees duab, cov vis dis aus lossis computer. Koj yuav tsum hloov pauv ntawm lub rooj tsavxwm mus rau cov vis dis aus uas koj xaiv. Cov zis tuaj yeem yog videocreen lossis beamer.

Tseem ceeb heev yog txoj kev uas koj pom cov khoom nyob rau ntawm xub ntiag ntawm lub koob yees duab. Qhov no cuam tshuam cov duab ntawm xya lub teeb ci ci. Nov yog daim vis dis aus nrog cov cim qub thiab ua tiav nrog tsuas yog ob peb qib teeb ci:

Kev ua yeeb yaj kiab cuam tshuam
