Ua Seismometer txhawm rau txheeb xyuas qhov av qeeg muaj zog thoob ntiaj teb rau qis dua $ 100! Slinky, qee cov hlau nplaum, thiab Arduino board yog cov khoom tseem ceeb ntawm no.

Kauj Ruam 1: Nws Ua Haujlwm Li Cas?

Qhov seismometer no pom cov lus tsa suab hauv av nrog cov hlau nplaum dai ntawm ib qho slinky. Cov hlau nplaum tsis pub thaws nce thiab nqis. Cov hlua hlau nyob ruaj ruaj tau muab tso rau ib puag ncig cov hlau nplaum. Txhua qhov kev txav ntawm cov hlau nplaum ua rau muaj cov dej me me hauv cov hlau, uas tuaj yeem ntsuas tau.

Tus so ntawm lub cuab yeej yog qhov tseem ceeb ntawm cov cuab yeej siv hluav taws xob los ntsuas cov dej me me hauv cov xaim thiab hloov pauv mus rau hauv cov ntaub ntawv peb tuaj yeem nyeem tau. Cov duab kos nrawm tau qhia.

1a: Caij Nplooj Ntoos Hlav (Slinky, Jr.), 1b: Hlau nplaum (ob lub RC44 lub nplhaib hlau nplaum)

2. Coil of Magnet Wire (MW42-4) Amplifier, hloov lub teeb liab tsis muaj zog mus rau qhov muaj zog

3. Analog-to-Digital Converter (Arduino), hloov cov teeb liab analog mus rau hauv cov kwj digital ntawm cov lej

4. Cov Ntawv Sau (PC), siv software los sau thiab tso saib cov ntaub ntawv

Kauj Ruam 2: Coil Qee Cov Hlau

Thawj qhov peb tau ua yog ua kom peb cov hlua hlau. Hauv peb thawj tus qauv, peb siv PVC lub kaus mom kawg nias rau ntawm qhov kawg ntawm ntu luv ntawm cov yeeb nkab los tsim phab ntsa ntawm ob sab ntawm cov xaim qhwv. Peb txiav cov qhov xaus kom qhib nws rov qab. Peb txiav ib ntu ntawm 1 PVC Yeeb Nkab thiab qhwv txog 2, 500 tig siv 42 gauge hlau nplaum hlau.

Cov yeeb nkab yog ib txoj hauv kev zoo los ua nws los ntawm qhov pheej yig, cov khoom siv tau yooj yim. Peb siv PVC lub hau kawg nias ntawm ob qho kawg ntawm ntu luv ntawm cov yeeb nkab los tsim cov phab ntsa ntawm ob sab ntawm cov xaim qhwv. Peb txiav cov qhov xaus kom qhib nws rov qab.

Peb tau ua qhov zoo nkauj ntawm cov xov hlau siv qee qhov luam tawm 3D. Qhov no tau yooj yim dua los qhwv, vim tias nws tau txuas nrog lub tshuab xaws-winding ntawm lub tshuab xaws qub. Hauv cov vis dis aus luv luv, koj tuaj yeem pom tias peb raug mob li cas. Yog tias koj tau nkag mus rau 3D Tshuab Luam Ntawv thiab xav siv peb cov qauv, qhia rau peb paub thiab peb tuaj yeem xa koj cov ntaub ntawv! Kuj nco ntsoov cov xov hlau loj hauv cov duab. Peb tau siv qhov kawg ntawm cov hlau nplaum hlau mus rau cov xaim tuab, uas yog qhov yooj yim dua los ua haujlwm nrog.

Kauj ruam 3: Dai/Calibrate Koj Slinky

Peb siv Slinky Jr uas muaj txoj kab uas hla me dua li qhov loj me me. Hauv qab, peb tau teeb tsa ob lub RC44 lub nplhaib hlau nplaum sib sau ua ke rau ntawm 6 qhov ntev ntawm #4-40 threaded rod.

Nyob rau sab saum toj ntawm slinky, peb tau teeb tsa lwm lub hlau nplaum rau ntawm lub phaj hlau rau qhov ntxig kom nqes mus. Hauv cov vis dis aus, peb qhia yuav ua li cas ntsuas koj li slinky ua 1 Hz. Qhov no yog kauj ruam tseem ceeb kom tau txais cov zaus kom raug. Cov slinky yuav tsum thaws nce thiab nqis ib zaug, hauv ib pliag.

Kuj tseem muaj R848 lub nplhaib hlau nplaum nyob hauv qab ntawm tus pas nrig. Cov hlau nplaum no nyob sab hauv ntawm ntu me me ntawm cov yeeb nkab tooj liab. Qhov no pab ua kom cov lus tsa suab qis, txo qis suab nrov, thiab pom tias qhov slinky tsuas yog thaws thaum muaj qhov tshee txaus!

Kauj Ruam 4: Tshaj Tawm Tam Sim No

Cov hlau nplaum txav sab hauv ntawm cov kauj hlau ua rau muaj cov dej me me heev, yog li peb yuav tsum ua kom nrov nrov ntxiv kom peb tuaj yeem pom lub teeb liab me me. Muaj ntau qhov zoo ntawm lub tshuab hluav taws xob zoo nyob rau ntawd, peb nyam mus rau hauv Circuit Court siv hauv TC1 seismometer peb pom hauv online. Hauv daim duab, koj tuaj yeem pom cov phiaj xwm rau amp Circuit. Peb tsuas yog siv daim ntawv qhia zaub mov!

Kauj Ruam 5: Npaum Qhov Teeb Meem Analog Rau Hauv Digital Digital ntawm Numbers

Arduino yog lub me me, pheej yig microprocessor uas nrov heev. Yog tias koj tsis muaj kev paub dhau los nrog qhov no, peb pom zoo kom pib nrog ib qho ntawm cov khoom siv qhia uas muaj.

Pawg tswj hwm Arduino siv lub teeb liab sib piv los ntawm lub tshuab hluav taws xob thiab txhais qhov ntawd mus rau hauv cov kwj ntawm cov lej, cov lej. Txhawm rau ua qhov no, Arduino tau teeb tsa txoj haujlwm los ntawm TC1 Seismometer qhov haujlwm uas tau hais hauv qhov pib ntawm Cov Lus Qhia no. Nov yog qhov txuas rau txoj haujlwm ntawd dua, uas tuaj yeem pab koj teeb tsa koj li Arduino!
