2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Oshman Engineering Design Kitchen (OEDK) yog lub chaw tsim khoom loj tshaj plaws ntawm Tsev Kawm Qib Siab Rice, muab chaw rau txhua tus tub ntxhais kawm los tsim thiab ua qauv qauv daws teeb meem rau ntiaj teb tiag. Txhawm rau ua lub hom phiaj no, OEDK muaj tsev cov cuab yeej siv hluav taws xob thiab cov tshuab loj uas ua rau nrov nrov, muaj suab nrov tsis nyab xeeb. Thaum OEDK tau ua tiav kev coj noj coj ua ntawm kev nyab xeeb nyob ib puag ncig kev tiv thaiv qhov muag thiab hnab looj tes, nws tsis tuaj yeem tsim kom muaj kev coj noj coj ua zoo ib yam nyob ib puag ncig kev tiv thaiv kev hnov lus, vim qhov tseeb tias cov neeg siv tsis paub meej thaum yuav tsum muaj kev tiv thaiv lub ntsej muag.

Peb pab neeg, Ntiv Nplhaib Decibels, lub hom phiaj los daws qhov teeb meem no los ntawm kev tsim qauv, tsim, thiab siv lub kaw lus ceeb toom uas qhia rau OEDK cov neeg siv kom tiv thaiv kev hnov lus tsim nyog ntawm qib suab tsis nyab xeeb.

Kauj ruam 1: Txheej txheem cej luam

Cov cuab yeej no siv Arduino Uno microcontroller. Cov ntaub ntawv suab zoo sib xws tau txais los ntawm Gravity Sound Level Meter, qhov nruab nrab, thiab tom qab ntawd siv los ua kom pom cov kab hluav taws xob LED. Cov duab pom pom suav nrog cov gradient uas nthuav qhia qhov nruab nrab decibel qib thiab txheej ntawm lub mloog pob ntseg uas ua rau liab liab thaum lub sijhawm txiav txim siab decibel tau pib ua ntej.

Lub casing yog tsim los ntawm ob daim ntawv plywood sib cais los ntawm ob daim plywood daim phiaj cais los ntawm aluminium standoffs. Cov gradient thiab lub mloog pob ntseg qhia tau tsim nrog frosted acrylic Txhua yam khoom siv hluav taws xob tau teeb tsa rau sab nraub qaum.

Los ntawm cov ntaub ntawv raw mus rau ntawm phab ntsa, cov cuab yeej no tsuas siv sijhawm tsawg dua 2 teev los ua kom tiav. Peb tau kawm ntau yam txog cov ntaub ntawv du thiab tswj cov hlua LED los ntawm txoj haujlwm no thiab peb vam tias koj muaj kev lom zem los tsim nws!

Kauj Ruam 2: Cheeb Tsam & Cov Cuab Yeej Xav Tau

Tus nqi tag nrho rau cov khoom siv rau lub cuab yeej no qis dua $ 100. Txij li thaum peb pab neeg tab tom tsim cov cuab yeej no ntau, peb muaj peev xwm yuav qee cov ntaub ntawv hauv ntau kom txo tus nqi. Tsis tas li, txij li peb tab tom tsim cov cuab yeej no rau thiab hauv chaw tsim khoom siv tshuab, peb tau nkag mus rau ntau yam ntawm cov khoom siv thiab cov cuab yeej twb tau ua lawm.

Hloov lub Circuit Court mus rau Perf Board (yeem)

Txhawm rau khaws tag nrho cov khoom siv hluav taws xob nyob hauv qhov chaw ntev dua, peb pab neeg tau txiav txim siab txav peb lub Circuit Court mus rau lub rooj tsav tsheb. Peb lub rooj sib tham tsis nyuaj heev, yog li peb siv lub hacksaw los txiav 4cm x 6cm perf board rau hauv 4cm x 3cm board thiab drilled qhov tshiab mounting qhov rau nws nrog 1/8 ntsis.

Kauj Ruam 5: Hloov kho thiab Tshaj Tawm Txoj Cai

Rub tawm cov cai thiab qhib nws hauv Arduino IDE.

Txheeb xyuas tias tus nqi tau teev tseg rau tus lej ntawm LEDs ntawm txhua kab (NUM_LEDS_1 thiab NUM_LEDS_2) sib phim tus lej ntawm LEDs koj txiav rau thawj LED kab txaij (gradient) thiab kab thib ob LED (lub mloog pob ntseg). Yog tias cov txiaj ntsig no tsis sib xws, hloov tus lej ntawm tus lej.

Txheeb xyuas thiab xa cov cai rau koj pawg Arduino.

Kauj Ruam 6: Npaj Ntoo Casing

Rub tawm cov ntawv ntoo txiav ntoo.

Laser-txiav cov phaj pem hauv ntej thiab sab nraub qaum thiab 6 LED txhawb nqa los ntawm 1/4 plywood siv cov chaw tsim nyog ntawm koj lub tshuab txiav laser. Xav tias hloov pauv lub logo uas tau muab tso rau ntawm lub phaj pem hauv ntej rau hauv cov qauv uas koj xav tau.

Ntawm peb lub tshuab txiav laser (EPILOG Fusion M2 40), peb siv cov chaw hauv qab no:

• 4 nrawm, 100 lub zog, 10 zaus rau vector-txiav
• 50 nrawm, 100 lub zog, 300 DPI rau raster-engrave

Peb siv lub tshuab txiav laser vim tias peb tau nkag mus rau ib qho ntawm OEDK, tab sis koj tseem tuaj yeem rub tawm cov ntaub ntawv los siv ua tus qauv los txiav cov ntu nrog CNC router lossis bandsaw.

Laum 3 qhov nrog 5/32 "ntsis rau hauv cov phaj pem hauv ntej hauv qhov chaw pom los ntawm Xs liab hauv daim duab. cov qhov no los ntawm sab xub ntiag. Cov qhov no yuav yog rau 2 "kev sawv ntsug.

Muab cov phaj pem hauv ntej tso rau sab saum toj ntawm lub phaj rov qab xws li lawv ob leeg tau taw qhia raws li pom hauv cov ntawv txiav laser. Nrog tus xaum, maj mam taug qab tus txheej txheem ntawm qhov gradient thiab lub mloog pob ntseg, lub qhov microphone thiab 3 qhov tsuas yog drilled hauv phaj pem hauv ntej mus rau phaj tom qab.

Laum 3 qhov nrog 5/32 ntsis rau sab nraub qaum hauv cov chaw uas nyuam qhuav pauv los ntawm phaj pem hauv ntej.

Kauj Ruam 7: Npaj cov Acrylic Pieces

Rub tawm 1/4 "acrylic laser-cutting file thiab 1/8" laser-cutting file.

Laser-txiav lub hauv ntej-ntxig daim los ntawm 1/4 "acrylic thiab daim thim rov qab los ntawm 1/8" acrylic siv cov chaw tsim nyog ntawm koj lub tshuab txiav laser. Ntawm peb lub tshuab txiav laser (EPILOG Fusion M2 40), peb siv cov chaw hauv qab no:

• 2 nrawm, 100 lub zog, 100 zaus rau 1/4 "acrylic
• 4 nrawm, 100 lub zog, 100 zaus rau 1/8 "acrylic

Ib qho ntxiv, daim thim rov qab tuaj yeem txiav los ntawm acrylic ntawm txhua qhov dav, tab sis peb pom 1/8 lossis thinner ua haujlwm zoo txaus rau txuas rau ntoo thaum txo qhov hnyav.

Kua nplaum txhua daim acrylic thim rov qab rau nws qhov sib thooj nkag rau sab nrog cov kua nplaum acrylic xws li thaum cov khoom tso rau pem hauv ntej tau muab tso rau hauv lub phaj pem hauv ntej, cov tab ntawm cov thooj ntawv thim rov qab nrog lub ntsej muag pem hauv ntej.

Tom qab cov kua nplaum tau teeb tsa (tsawg kawg 30 feeb), ua rau sab pem hauv ntej thiab nraub qaum ntawm cov khoom sib xyaw ua ke kom pom lub teeb zoo dua. Peb siv cov xuab zeb blaster rau qhov no, tab sis nplua-cov ntawv xuab zeb (600 pob zeb lossis siab dua) thiab qee lub luj tshib roj yuav ua haujlwm ib yam.

Kauj Ruam 8: Txuas cov Acrylic Pieces rau Ntoo Casing

Teem lub phaj pem hauv ntej lub ntsej muag thiab ua kom qhuav haum cov khoom acrylic rau hauv lawv qhov chaw sib xws. Yog tias cov khoom siv acrylic muaj qee qhov teeb meem haum, xuab zeb sab hauv ntawm lub phaj pem hauv ntej kom txog thaum daim acrylic haum.

Thaum ua tiav qhov ua tau zoo, tshem cov acrylic daim ntawm cov phaj pem hauv ntej thiab siv ob-ntu epoxy rau lub ntsej muag ntawm cov tab ntawm cov thaub qab uas kov ntoo. Muab cov ntawv acrylic tso rau hauv lawv qhov chaw, nias qis, thiab cia cov epoxy qhuav tag.

Kauj Ruam 9: Mount Cov Khoom Siv Hluav Taws Xob rau Ntoo Casing

Siv cov txheej txheem taug qab ntawm lub microphone lub qhov nyob rau sab nraub qaum, tso lub Gravity Sound Level Meter rau sab nraub qaum xws li lub microphone haum nrog nws cov qauv. Kos rau qhov twg plaub qhov sib dhos ntawm Lub Rooj Tsav Xwm Gravity nyob ntawm daim phaj nraub qaum.

Tawm Hauv Lub Ntiaj Teb Lub Suab Qib Siab ntawm lub phaj rov qab, teeb tsa Arduino board thiab perf board nyob rau sab nraub qaum. Taw qhia Adruino pawg thawj coj xws li lub qhov hluav taws xob yuav taw tes qis thiab tawm tsawg kawg yog 1/4 ntawm qhov chaw nruab nrab ntawm txhua lub rooj tsavxwm. cov txheej txheem ntawm cov gradient thiab lub mloog pob ntseg. Peb tau xaiv muab Arduino board rau sab laug ntawm Pawg Gravity thiab daim phiaj perf saum toj ntawm Pawg Gravity.

Kos rau qhov twg qhov kev teeb tsa yog rau Arduino thiab cov laug cam nyob rau sab nraub qaum.

Tshem tawm cov khoom siv hluav taws xob los ntawm daim phiaj rov qab thiab laum txhua lub qhov tsuas yog cim nrog 1/8 laum ntsis. laum xovxwm.
