Video: Kev Npau Suav ntawm Stylophone Ntsiab Lus: 7 Kauj Ruam (nrog Duab)
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27
Kuv txiav txim siab los ua cov khoom siv suab paj nruas hluav taws xob ua khoom plig Christmas rau kuv tus tub. Kuv tau tshawb xyuas Lub Vev Xaib nrhiav kev tshoov siab thiab pom Stylophone, lub cuab yeej uas kuv ua raws kuv tus kheej tsim. Qhov tseeb, Kuv tau hloov cov yuam sij luv ntawm Stylophone nrog cov ntawv ntev, yog li tsim ib hom ntawv sau. Qhov tseeb, koj tuaj yeem sau cov cim thiab txawm tias lo lus ntawm lub ncoo no, thiab txhua tus cim yuav muaj nws tus kheej 'suab zoo ib yam'. Kuv xav tias nws yuav muaj txiaj ntsig rau cov menyuam uas kawm sau ntawv, ua rau cov txheej txheem kev kawm lom zem.
Kab lus no tseem tau tshaj tawm hnub no (21 Lub Ob Hlis 2019) hauv Ceev thiab Volts, cov ntawv xov xwm rau kev nyiam siv tshuab hluav taws xob zoo.
Kauj ruam 1: Circuit Court
Lub hauv paus tseem ceeb yog qhov ua tau zoo oscillator ua nrog
IC 555; koj tuaj yeem pom cov lus piav qhia yuav ua li cas Circuit Court no ua haujlwm, piv txwv li, ntawm www.electronics-tutorials.com. Qhov zaus ntawm qhov oscillations nyob ntawm qhov muaj nuj nqis ntawm R1, R2 thiab C1, thiab suav raws li:
(1) f = 1.44/(R1 +2*R2)*C1
Yog li, yog tias koj xav hloov pauv zaus, koj yuav tsum hloov pauv R lossis C. Thaum ua si Stylophone koj hloov R2 los hloov qhov zaus ntawm lub suab. Kuv hloov cov qauv (1) cais R2:
(2) R2 = 1/2* {1.44/(f* C1) - R1}
Qhov ntau ntawm kuv lub cuab yeej suav nrog 12 qhov sau tseg - los ntawm C6 (xaiv ntawm qhov xav tau) mus rau C5#/D5b; yog vim li cas qhov no thiaj li yog cov duab geometrical - Kuv siv lub thawv ntoo uas muaj (198 x 98 x 31mm) ua lub thawv rau lub cuab yeej, thiab muaj txhuas kab txaij 7 hli dav; yog li, tsuas yog 12 tus yuam sij haum rau hauv qhov dav ntawm lub npov.

A5 880.00 Nws
A#5/Bb5 932.33
B5 987.77 ib
C6 1046.50
Ib lub rooj tiav tuaj yeem pom ntawm no:
Wb coj R1 = 10 kΩ thiab C1 = 100 nF, tom qab ntawd R2 rau qhov zaus ntawm C6 (1046.50 Hz) suav nrog tus lej (2) yog 1876 ohm (sib npaug rau tus lej tag nrho). Cov txiaj ntsig rau lwm qhov zaus tuaj yeem suav tau tib yam; qhov tsawg zaus, qhov loj dua tus nqi ntawm R2. Cia peb ntxiv cov tshuaj tiv thaiv kab mob (R3, R4, thiab lwm yam) rau R2; tom qab ntawd, thaum koj kov lub ntsiab lus 'Key1' nrog tus stylus, nws yog (R2 + R3) uas txuas nrog rau hauv Circuit Court; thaum koj kov lub ntsiab lus 'Key2', koj txuas (R2 + R3 + R4), thiab ntxiv rau. Yog li, tus nqi R3 yog xam raws li:
(3) R3 = 1/2*{1.44/(f (B5)*C1) - R1} - R2, qhov twg f (B5) - yog qhov sib xws sib xws rau daim ntawv B5
Lwm qhov txiaj ntsig tau suav nrog tib txoj hauv kev, lawv tau qhia hauv daim nqi ntawm cov ntaub ntawv. Yog tias koj xav tau los suav qhov txiaj ntsig tshiab, koj tuaj yeem siv lub laij lej online, piv txwv li, ib qho los ntawm lub xaib no: www.ohmslawcalculator.com. Qhov tseem ceeb ntawm cov resistors tsis yog tus qauv, nws yog qhov tsim nyog los ua ke tus nqi xav tau los ntawm tus qauv; Txawm li cas los xij, koj tuaj yeem hloov cov neeg tiv thaiv mus tas li nrog cov kws txiav plaub hau thiab tsim kom tau qhov txiaj ntsig xav tau siv lub ohmmeter.
Cov kab hluav taws xob tau teeb tsa ntawm lub phaj perforated, kev sib txuas tau ua nrog cov xov hlau hloov pauv tau. Kuv qhia kom muab cov khoom tso rau ntawm phaj raws nraim li lawv tau teeb tsa hauv daim duab kos.
Kauj Ruam 2: Nqi Khoom
IC1 = NE555
R1 = 10 kΩ, R2 = 1876Ω, R3 = 411Ω, R4 = 438Ω, R5 = 456Ω, R6 = 482Ω, R7 = 520Ω, R8 = 546Ω, R9 = 570Ω, R10 = 626Ω, R11 = 650Ω, R12 = 690Ω, R13 = 730 hli; txhua tus tiv thaiv muaj lub zog ntsuas ntawm 0.125W
C1 = 100 nF, tej hub; C2 = 10 mF x 10V, electrolytic
LS1 - tus hais lus nrog qhov tsis txaus ntseeg ntawm 8 ohm.
SW1 - me me toggle swb hloov
B1 = 4 x 1.5 V roj teeb hom AA
Kauj Ruam 3: Kev Npaj Lub Cev
Koj pom sab nraud thiab sab hauv ntawm lub cuab yeej ntawm cov duab; koj muaj kev ywj pheej xaiv koj tus kheej txoj hauv kev los teeb tsa cov khoom hauv lub npov.
Kauj ruam 4: Cov yuam sij
Kuv ua rau lawv los ntawm cov kab hlau txhuas ntawm ntu ntu 7x1mm. Ib txheej nyias ntawm aluminium oxide uas tau tsim nyob rau saum npoo ntawm cov yawm sij tiv thaiv lawv los ntawm kev ntxiv oxidation tab sis tsis tiv thaiv hluav taws xob sib txuas ntawm cov yuam sij thiab cov stylus. Cov duab qhia pom daim duab ntawm tus yuam sij thiab tseem piav qhia yuav ua li cas txuas cov xov hlau rau cov yuam sij thiab kho cov yuam sij rau lub thawv. Nws yog ib qho tseem ceeb uas ob sab ntawm cov yuam sij tsis muaj chamfers, txwv tsis pub cov stylus yuav tsis txav mus los ntawm qhov chaw.
Kauj ruam 5: Stylus
Kuv ua tus stylus los ntawm tus cwj mem pob uas ua tiav nws cov kev pabcuam. Qhov kev sib cuag uas kov cov yuam sij yog, qhov tseeb, tus pin ntawm qhov txuas hluav taws xob; Kuv tau siv cov xaim hloov pauv tau rau nws, muab tus pin tso rau hauv tus cwj mem thiab sau qhov chaw ib puag ncig tus pin nrog pob tshab pob tshab. Muaj qhov yuav tsum tau ua: qhov kawg ntawm tus pin yuav tsum yog ib nrab puag ncig thiab muaj lub ntsej muag du, nws tsim nyog kom tsis txhob khawb cov yuam sij.
Kauj Ruam 6: Cov Cuab Yeej thiab Cov Cuab Yeej
Koj yuav tsum xav tau lub ntsuas hluav taws xob, yog tias koj siv lub tshuab txiav los tsim qhov xav tau ntawm R3, R4, thiab lwm yam; yog tias koj xav tau txais cov ntawv sau meej, koj tuaj yeem siv kamerton los kho lub cuab yeej. Yuav tsum tau siv cov hlau txuas thiab lub tshuab txiav hlau los sib dhos ua ke; me me hacksaw, laum thiab cov ntaub ntawv - los ua tus yuam sij. Txawm li cas los xij, koj qhov kev xaiv ntawm lwm cov cuab yeej nyob ntawm qhov feem ntau nyob ntawm qhov thaiv uas koj yuav ua rau koj lub cuab yeej; Kuv tsis suav tias muaj leej twg yuav 3D-luam nws.
Kauj ruam 7: Yees duab
Daim vis dis aus no qhia koj yuav tsim lub suab zoo li cas 'ntawm tus ua cim.
