Nov yog qhov haujlwm kuv tab tom ua tam sim no rau kuv lub koom haum sib ntaus sib tua neeg hlau. Nws yog lub teeb ci LED uas yuav teeb liab rau cov tsav tsheb thaum kev sib tw yuav pib. Nov yog cov hom phiaj kuv tau tsom mus rau:- Lub cev zoo ib yam li cov teeb pom kev zoo qub uas ncua nyob nruab nrab ntawm kev sib tshuam.- Tswj tsis muaj microprocessor (piv txwv li tsis muaj Arduino)- Sab hauv lub zog siv uas tuaj yeem ua haujlwm rau ntau qhov hnub.- Tiv thaiv los ntawm shrapnel thiab ya neeg hlau.- Koom nrog lub suab zoo li lub teeb.- Ua kom pom kev zoo nkauj thiab txias txias! Kuaj hauv tsev: Ib qho vis dis aus ntawm nws ua (nrog qhov ci ci ci):

Kauj Ruam 1: Tsim Circuit Court

Ib yam li kuv tau hais ua ntej kuv xav ua kom tiav lub sijhawm tswj hwm yam tsis siv lub microprocessor. Kuv siv lub 555 timer IC raws li nws yooj yim siv thiab kuj tseem pheej yig heev thiab. Qhov Circuit Court tau tsim los kom muaj qhov hloov pauv ib ntus ua rau pom thawj zaug, thiab lub teeb tom ntej tau tshwm sim thaum thawj lub teeb kaw. Rov ua dua raws li qhov tsim nyog. Cov txheej txheem kuv tau hacked ua ke ntawm no (cov khoom siv rau kpsec.freeuk.com) qhia tau hais tias kuv tau xaim liab thiab daj ntu ntawm Circuit Court. Koj yuav tsum tau ntxiv 555 timer 'ntu' rau txhua lub teeb. Kuv siv 100k resistors kom tau kwv yees li ntawm 1.1 vib nas this rau txhua lub voj voog. Yog tias koj hloov R1/R2 nrog lub lauj kaub 1 megaohm koj tuaj yeem yooj yim sib txawv lub sijhawm ntawm koj li Circuit Court. Ua li 555 lub sijhawm teev tuaj yeem poob mus txog 200mA ntawm qhov tam sim no uas ntau tshaj li txaus rau ib txhais tes ntawm LEDs. Hauv kuv qhov xwm txheej kuv siv 36 LEDs rau 555 lub sijhawm uas kos kwv yees li 120mA.

Kauj ruam 2: Tsim Circuit Court

Txhawm rau txuas kuv lub Circuit Court Kuv tau khaws lub rooj sib tham proto los ntawm lub khw muag khoom hluav taws xob hauv zos. Nqi kuv li $ 5 thiab kuv tuaj yeem yuav haum txog 3 ntawm cov kab hluav taws xob no rau nws. Kuv txiav tawm ib qho uas kuv xav tau nrog dremel. Kuv kuaj PCB nrog qee qhov LEDs nkaus xwb thiab nws ua haujlwm tau zoo heev. Qhov ntsuas lub voj voos kos txog 30mA vim nws 'tsis ua haujlwm' uas tsis muaj lub teeb ci.

Kauj Ruam 3: Lub Thawv Tswj

Txhawm rau tsev tswj hwm lub rooj sib tham, hloov pauv, thiab roj teeb Kuv tau khaws lub thawv yas los ntawm lub khw muag khoom hluav taws xob hauv cheeb tsam txog $ 5 ib yam. Qhov sib txawv ntawm qhov koj pom sab hauv: Qhov loj loj "pib" khawm hloov uas yog lub tshuab arcade/pinball. Tau nws los ntawm Electronic Goldmine.11.1V 1000mAh Li-poly roj teeb uas kuv tau txais los ntawm Hobby King.15A toggle hloov uas yuav yog tus tswv lub zog hloov pauv, tau txais los ntawm lub khw pib tsheb hauv ib cheeb tsam. 5kohm lauj kaub uas yuav tsum tau ua raws li kho qhov ci ci. Kuv suav nrog nws raws li kuv muaj ob peb tso nyob ib puag ncig tab sis nws tau dhau los ua qhov tsis muaj txiaj ntsig zoo li tus nqi tau siab dhau. 12V beeper module los ntawm lub khw muag khoom hluav taws xob hauv zos.

Kauj ruam 4: LEDs

Cov LEDs kuv siv yog qhov tshwj xeeb me ntsis. Ib qhov haujlwm qub ntawm kuv tau tsim teeb sab hauv LED rau kuv lub tsheb. Kuv siv 5mm 'super flux' LEDs thiab txawm tias muaj kev cai PCBs ua rau lawv. Kuv tshwj xeeb xaj qee qhov ntsuab thiab daj LED rau txoj haujlwm no thiab muab tag nrho cov teeb pom kev uas kuv xav tau. Qhov pawg thawj coj muaj 9 LEDs. (3 txoj hlua ntawm 3 kab hauv kab) Kev khiav tawm 11-15V thiab muaj cov tswv yim tawm tswv yim (tiv thaiv hluav taws xob rov qab) thiab 3 qhov hluav taws xob tiv thaiv sab saum toj.

Kauj Ruam 5: LED Vaj Tsev

Txhawm rau teeb tsa cov laug cam LED Kuv siv ib feem ntawm 2.5 txhuas tubing uas yog tib yam khoom kuv tau siv hauv kuv li RC Nerf Tank project..

Kauj Ruam 6: Cov Ntaub Ntawv Tiv Thaiv

Txhawm rau kom LEDs nyab xeeb los ntawm kev puas tsuaj Kuv tau kaw lawv hauv lub thawv polycarbonate meej. Qee qhov nws yog 1/8 "thiab qee qhov yog 1/4" tuab. Tapped thiab ntsia hlau ua ke nrog cov ntsia hlau ntsaws.

Kauj Ruam 7: Sib dhos thiab thaiv thiab sim nws tawm

Kuv xaim cov LEDs rau lub thawv tswj ib ntus, kuv yuav tsum ua kom ntev dua cable thaum nws txuas rau ntawm thaj chaw. Nws zoo li ua haujlwm tau zoo tshwj tsis yog kuv yuav tsum tshem lub beeper. Kuv xav tias tej zaum nws yuav kos ntau dhau tam sim no raws li 55 lub sijhawm kawg tuag thaum kuv thawj zaug sim nws. Kuv hloov nws thiab txuas tus beeper thiab tam sim no nws ua haujlwm tau zoo heev.
