Muaj ntau qhov kev txaus siab hauv cov leeg siv hluav taws xob siv hluav taws xob, vim feem ntau ua tiav ntawm Perpetual TorchPerpetual Torch, tseem hu ua roj teeb-tsawg LED teeb. Lub roj teeb uas tsis muaj roj teeb muaj lub tshuab hluav taws xob tsim hluav taws xob rau LEDs, hluav taws xob hluav taws xob kom zoo thiab khaws cov hluav taws xob tsim los ntawm lub tshuab hluav taws xob hluav taws xob thiab ua haujlwm siab dawb LEDs. Cov leeg hluav taws xob siv hluav taws xob tsim hluav taws xob yog ua raws Faraday txoj cai, suav nrog lub raj nrog cov hlau nplaum cylindrical. Lub raj yog qhov txhab nrog lub kauj ntawm cov hlau nplaum hlau. Raws li lub raj tau tshee hnyo, cov hlau nplaum hla qhov ntev ntawm lub raj rov qab los, yog li hloov pauv cov hlau nplaum los ntawm cov kauj thiab cov kauj thiaj li ua rau AC voltage. Peb yuav rov los rau tom qab no hauv Cov Lus Qhia. Cov Lus Qhia no qhia koj yuav tsim lub tshuab hluav taws xob, tsis siv lub tswb li cas. Ib daim duab ntawm chav tsev ua tau pom hauv qab no. Tab sis ua ntej qee qhov keeb kwm yav dhau -
Kauj Ruam 1: Cov Hluav Taws Xob Hluav Taws Xob
Hloov chaw ntawm ib txwm tsuav, nws yog qhov zoo thiab txias siv cov tsuav hluav taws xob. Feem ntau xws li cov tsuav yuav suav nrog cov khoom siv hluav taws xob thiab cov duab LED. Cov zaub LED tuaj yeem yog xya ntu tso saib uas tuaj yeem tso saib tus lej ntawm 1 thiab 6 raws li pom hauv qab no lossis tej zaum, kom ua raws li cov qauv tsaj ib txwm muaj, nws tuaj yeem suav nrog 7 LEDs teeb tsa raws li qhia hauv daim duab thib ob. Ob lub tsuav tsim muaj qhov hloov pauv, uas tus neeg siv yuav tsum nias thaum nws/nws xav "yob lub tsuav" (lossis "yob lub tuag"?). Qhov hloov pauv ua rau tus lej tsim hluav taws xob tau teeb tsa hauv lub microcontroller thiab tus lej tsis raug yog tom qab tso tawm ntawm xya ntu tso saib lossis tso saib LED. Thaum tus neeg siv xav tau tus lej tshiab, qhov hloov pauv yuav tsum tau nias dua.
Kauj Ruam 2: Lub Hwj Huam Fais Fab rau Tsuav
Ob qho kev tsim qauv qhia hauv cov kauj ruam dhau los xav tau lub zog tsim nyog uas tuaj yeem muab tau los ntawm cov kab mob hauv phab ntsa, kho qhov tsim nyog, kho lub tshuab hluav taws xob kom zoo thiab tsim nyog +5V tus tswj hwm. Yog tias tus neeg siv xav tau kev txav chaw ntawm cov tsuav, tom qab ntawd cov phab ntsa wart hloov pauv yuav tsum tau hloov nrog lub roj teeb uas tsim nyog, hais tias 9V roj teeb. Lwm txoj hauv kev rau lub roj teeb muaj nyob, piv txwv li, kom tuaj yeem ua haujlwm tsuav los ntawm ib leeg AA lossis AAA roj teeb, tus tswj kab ib txwm yuav tsis ua haujlwm. Txhawm rau kom tau txais +5V rau kev ua haujlwm tsuav, yuav tsum siv hom DC-DC hloov pauv kom haum. Daim duab piav qhia txog +5V lub zog xa khoom haum rau kev ua haujlwm tsuav los ntawm phab ntsa 9V roj teeb thiab lwm daim duab qhia pom lub tswv yim rau +5V fais fab mov los ntawm 1.5V AA lossis AAA hom roj teeb siv TPS61070 txhawb DC-DC hloov pauv.
Kauj Ruam 3: Lub Hwj Chim Dawb: Siv Koj Cov Ncauj …
Cov kauj ruam no piav qhia cov leeg siv hluav taws xob tsim hluav taws xob. Lub tshuab hluav taws xob muaj lub raj Perspex ntawm 6 nti ntev thiab sab nrauv 15 mm. Sab hauv txoj kab uas hla yog 12 hli. Ib qhov zawj txog 1 hli tob thiab 2 ntiv tes ntev yog tshuab rau sab nrauv ntawm lub raj. Qhov zawj no yog qhov txhab nrog txog 1500 tig nrog 30 SWG hlau nplaum hlau. Ib txheej ntawm peb lub ntiaj teb tsis tshua muaj hlau nplaum cylindrical tau muab tso rau hauv lub raj. Cov hlau nplaum yog 10 hli txoj kab uas hla thiab 10 hli ntev. Tom qab tso cov hlau nplaum hauv lub raj, qhov kawg ntawm lub raj tau ntim nrog cov khoom ib puag ncig ntawm cov khoom siv liab qab PCB thiab lo nrog ob ntu epoxy thiab nrog qee qhov poob siab nqus cov pawm hauv (Kuv siv IC ntim ua npuas ncauj). Cov raj zoo li no muaj los ntawm McMaster (mcmaster.com), tus lej naj npawb: 8532K15. Cov hlau nplaum tuaj yeem yuav los ntawm amazingmagnets.com. Tshooj # D375D.
Kauj Ruam 4: Kev Siv Hluav Taws Xob Hluav Taws Xob
Cov leeg nqaij lub zog hluav taws xob ua haujlwm tau zoo npaum li cas? Nov yog qee qhov kev tshuaj ntsuam oscilloscope. Nrog maj mam co, lub tshuab hluav taws xob muab txog 15V qhov siab tshaj plaws. Qhov luv luv tam sim no yog li 680mA. Txaus txaus rau txoj haujlwm no.
Kauj ruam 5: Tsuav Schematic
Cov kauj ruam no qhia txog daim duab qhia chaw rau lub tsuav. Nws suav nrog lub kho hluav taws xob txuas hluav taws xob txuas hluav taws xob txhawm rau txhim kho AC voltage tsim los ntawm Faraday lub tshuab hluav taws xob thiab lim nrog 4700uF/25V electrolytic capacitor. Lub zog hluav taws xob tau tswj hwm nrog LDO, LP-2950 nrog rau 5V tso zis hluav taws xob, uas yog siv los muab hluav taws xob xa mus rau qhov seem ntawm lub Circuit Court, suav nrog microcontroller thiab LEDs. Kuv siv 7 qhov ua tau zoo 3-hli xiav LEDs hauv pob tshab pob tshab, teeb tsa hauv daim ntawv "tsuav". Cov LEDs raug tswj los ntawm 8-pin AVR microcontroller, ATTiny13. Qhov hluav taws xob tso tawm los ntawm lub tshuab hluav taws xob faraday yog lub zog tso tawm. Qhov kev tso tawm pulse no tau kho nrog kev pab ntawm tus tiv thaiv (1.2KOhm) thiab Zener diode (4.7V). Qhov ntsuas qhov ntsuas hluav taws xob tau hnov los ntawm lub microcontroller los txiav txim siab yog tias lub raj raug tshee. Tsuav yog lub raj tau tshee, lub microcontroller tos. Thaum tus neeg siv nres lub raj, lub microcontroller tsim tus lej tsis raug, siv tus lej sab hauv 8-ntsis ua haujlwm nyob rau hauv hom khiav dawb thiab tso tawm tus lej tsis sib xws ntawm 1 thiab 6, ntawm cov LEDs tso tawm. Lub microcontroller tom qab ntawd tos rau tus neeg siv kom co lub raj dua. Thaum cov LEDs tso saib tus lej tsis raug, tus nqi them ntawm lub capacitor txaus los teeb lub LEDs rau lub sijhawm nruab nrab li ntawm 10 vib nas this. Txhawm rau kom tau tus lej tsis raug tshiab, tus neeg siv yuav tsum co lub raj ob peb zaug ntxiv.
Kauj Ruam 6: Programming Microcontroller
Tiny13 microcontroller ua haujlwm nrog sab hauv RC oscillator programmed los tsim kom muaj 128KHz moos teeb liab. Qhov no yog lub moos qis tshaj plaws uas Tiny13 tuaj yeem tsim tau sab hauv thiab raug xaiv los txo qhov kev siv tam sim no los ntawm lub microcontroller. Qhov kev tswj hwm tau teeb tsa hauv C siv AVRGCC tus neeg sau thiab daim ntawv qhia ntws tau pom ntawm no. pom ntawm no. Kuv siv STK500 los ua haujlwm rau kuv Qhov Me Me, tab sis koj tuaj yeem xa mus rau Cov Lus Qhia no yog tias koj nyiam AVR Dragon programmer: https://www.instructables.com/id/Help%3a-An-Absolute-Beginner_s-Guide- rau-8-ntsis-AVR-Pr/
