Tv-B-Gone Hat: 6 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:30

Nov yog lub kaus mom nrog Tv-B-Gone ua ke thiab ob peb ntxiv cov yam ntxwv xws li hom hluav taws kub ceev uas yuav tua (thiab qhib) cov TV uas nquag siv ntau dua thiab tsis tu ncua ntawm hom uas yuav rov ua dua cov lej rau txhua lub tv tsis tas li.

Kauj Ruam 1: Sau cov Khoom

Cov ntaub ntawv

1 TV-B-Gone 1 Hat 1 555 Timer IC 1 5V Relay 3 IR LED's 2 Micro-Switches 1 0.1uF Capacitor 1 220uF Capacitor 1 10K Resistor 1 100K Potentiometer TOOLS Soldering Hlau Hlau Cutters/Strippers Plyers Xaws Khoom

Kauj Ruam 2: Tsim Timer Circuit

Peb yuav teeb tsa lub sijhawm nyob rau hauv hom kev pom zoo qhov kev xav tau zoo nyob ntawm nplooj 9 ntawm NE555 cov ntawv los ntawm Texas Instruments, muaj nyob ntawm: https://www.ortodoxism.ro/datasheets/texasinstruments/ne555.pdfRa = 100K potRb = 10K resC Nco ntsoov tias tus pin 4 tej zaum yuav tsis txuas nrog thiab kuv tau hloov qhov 0.01uF capacitor hauv qhov ntsuas nrog 0.1uF, ib qho yuav ua haujlwm. Thawj qhov uas yuav tsum tau ua yog tshem tawm cov coj uas peb tsis siv, qhov no pins 4 thiab 5 yuav tsum raug tshem tawm. Tom ntej khoov tus pin 2 hauv qab ntawm lub timer, qhov no yuav txuas nrog tus pin 6. Ua kom cov hlau lead uas seem siv ob peb plyers me me tam sim no tias IC tau npaj cov khoom tuaj yeem ntxiv tau. Nws yog ib qho tseem ceeb kom khaws cov txheej txheem kom tiaj li sai tau vim qhov no yuav raug teeb tsa ntawm daim nqi ntawm lub kaus mom. Thaum tag nrho cov khoom siv tau ntxiv cov xov hlau txuas rau gnd rau tus pin 1, lub zog rau tus pin 8 thiab lub sijhawm tso tawm rau tus pin 3.

Kauj Ruam 3: Txuas Txuas Txuas

Yog tias koj qhov xa tawm tsis tuaj nrog cov ntawv teev tseg lossis cov ntaub ntawv muaj txiaj ntsig koj yuav zaum yuav tsum xam tawm tus pin twg uas yog ntawm koj tus kheej. Txhawm rau ua qhov no siv lub ntsuas ntsuas ntsuas ntawm txhua qhov ua tau ua ke ntawm cov pins kom pom ib khub uas muaj kev tiv thaiv ntawm ob peb K ohms. Qhov no yog lub kauj. Txuas cov hlua mus rau 5v cov khoom siv thiab tshuaj xyuas qhov txuas ntxiv ntawm lwm tus lej sib txuas, thaum koj pom qhov sib txuas ua ntu zus, tshem tawm lub zog los ntawm kev xa tawm. Yog tias ob tus pin tseem niaj hnub saib txuas ntxiv (tseem sim thim rov qab qhov sib txawv ntawm 5v mov). Yog tias qhov kev sib txuas txuas tawg ces cov no yog NO (Feem ntau Qhib) pins, tus pin peb xav tau.

Txuas qhov tso tawm ntawm 555 mus rau + sab ntawm lub kauj thiab txuas cov kauj gnd mus rau tus pin 1 ntawm 555. Tom ntej no ntxiv cov xov hlau rau ob tus pin koj tsuas yog kho kom zoo li TSIS tau hu.

Kauj Ruam 4: Hloov Kho Tv-B-Gone

Qhib rooj plaub thiab tshem tawm lub rooj tsav xwm hauv Circuit. Cov xov tooj cua ntawm Tv-B-Gone yog qhov yooj yim zoo nkauj yog li peb qhov kev hloov kho tsis zoo li qub. Tshem tawm IR LED thiab hloov nws nrog cov xov hlau. Cov kab hluav taws xob txuas tom ntej mus rau sab nraud ntawm lub laub khawm hloov. Txij ntawm no peb tau xaiv los tsuag xim peb lub rooj tsavxwm dub. Tig lub rooj tsavxwm hla thiab txuas rau +6v thiab gnd.

Kauj Ruam 5: Txuas lub Circuitry rau lub kaus mom

Koj tuaj yeem tso qhov no rau txhua qhov chaw koj xav tau tab sis sab hauv qab ntawm daim nqi zoo li qhov chaw txaus nyiam tshaj plaws. Xaws los ntawm daim nqi ntawm lub kaus mom nqus tab sis nws ua haujlwm, txuas hauv av los ntawm 555 mus rau Tv-B-Gone hauv av thiab txuas cov txiaj ntsig los ntawm kev xa mus rau ob sab ntawm lub laub hloov. Tom ntej no khiav cov xaim los ntawm tus lej 8 ntawm 555 (+) thiab 6v cov khoom siv los ntawm Tv-B-Gone mus rau ib qho kev hloov swb thiab ob seem uas ua los ntawm lub laub khawm hloov mus rau qhov swb thib ob. Thaum kawg txuas rau peb IR LED's hauv kab rau LED tso tawm ntawm Tv-B-Gone. Tias nws. Ua tiav

Kauj Ruam 6: Siv Nws

Qhov swb swb uas txuas ncaj qha rau lub laub khawm hloov tso Tv-B-Gone mus rau hauv hom rov ua dua qhov nws rov ua dua 60 lub hlis thib ob tas mus li. Qhov swb swb txuas nrog 555 lub sijhawm ua rau lub kaus mom mus rau qhov hluav taws kub sai uas nws yuav rov ua thawj X vib nas this ntawm tv tawm cov lej (cov no yog cov lej ntau uas tau tso ua ntej). Txhawm rau kho tus naj npawb ntawm vib nas this ua ntej lub voj voog rov ua dua kho 100K lub zog, tus nqi zoo yog li 70K. Nco ntsoov tias yog tias rov hloov pauv ntawm qhov hluav taws kub nrawm yuav tsis muaj kev cuam tshuam.

Txhawm rau sim tawm koj qhov kev tsim siv lub xov tooj ntawm tes nrog lub koob yees duab, muab lub xov tooj ntawm tes rau hauv kev thaij duab thiab taw tes rau ntawm IR LED tom qab ntawd nyem lub pob nyem ntawm Tv-B-Gone. Koj yuav tsum tuaj yeem soj ntsuam LED ntsais ntawm lub vijtsam ntawm lub xov tooj ntawm tes. Thaum koj paub tseeb tias nws ua haujlwm koj yuav tsum siv qee lub sijhawm tsom mus rau LEDs kom raug kom lawv tua tvs koj tab tom saib thiab lawv tsis tau txais kev tiv thaiv los ntawm daim nqi ntawm lub kaus mom.
