Txoj haujlwm no tau ua tiav los ntawm Donovan New uas yog ib feem ntawm nws daim ntawv kawm tiav qib siab hauv Pomona College hauv chav haujlwm physics thiab astronomy. Cov ntaub ntawv no tau hloov kho zaum kawg Tsib Hlis 3, 2019.

Cov lus qhia no muab cov ntaub ntawv luam tawm 3D thiab cov lej arduino siv los tsim lub zog siv hluav taws xob uas siv tau uas nws lub zog tso tawm tau saib xyuas los ntawm cov ntaub ntawv logger. Qhov no tso cai rau ib qho los ntsuas lub zog uas tau sau los ntawm tib neeg cov lus tsa suab siv piezoelectricity. Tus qauv tsim suav nrog onboard Arduino nrog SD daim npav cov ntaub ntawv logger. Tus neeg hais lus tuaj yeem suav nrog rau kev tawm suab lub sijhawm tiag tiag ntxiv rau kev sib sau cov ntaub ntawv ntawm tus nqi hluav taws xob tsim hauv txhua qhov kev sim.

Kauj Ruam 1: Qhov Chaw

Txoj haujlwm no yog tsim los rau hauv qab no piezoelectric bimorph transducer:

Nruab nrab PPA-2011 ($ 274)

Rau Arduino, peb siv Uno Rev3:

Arduino ($ 22) Cov.

Txhawm rau txiav cov ntaub ntawv, peb siv Adafruit SD daim npav sau ntawv:

Cov ntaub thaiv npog cov ntaub ntawv ($ 17 suav nrog lub taub hau)

Ib qho tseem xav tau cov ntu ntxiv (SD daim npav, thauj khoom tiv thaiv, ua kom lub zog hloov pauv, txhim kho choj, 9 V roj teeb rau ua kom lub zog arduino, cov txiv ntoo me me thiab ntsia liaj qhov rooj, thiab cov xov txuas txuas/txuas).

Kauj Ruam 2: Cov Kuaj Cov Kuaj Lab

Cov ntaub ntawv txuas ntawm no tuaj yeem siv rau 3D luam tawm lub clamp uas tuav lub tshuab hluav taws xob nyob rau sab saum toj ntawm cov lus oscillating.

Kauj Ruam 3: Cov Kuaj Cov Khoom Siv

Ob.stl cov ntaub ntawv txuas ntawm no tuaj yeem siv rau 3D luam tawm rooj plaub rau tuav lub tshuab hluav taws xob thiab cov ntaub ntawv teev npe.

Cov ntaub ntawv.iso txuas nrog ntawm no muaj cov qauv duab arduino siv rau kev khaws cov ntaub ntawv.

Ib daim duab ntawm peb qhov kev sib tw zaum kawg tau pom.

Piv txwv cov ntaub ntawv tau qhia rau qhov tso tawm (hauv volts hla 20 kOhm load resistor tom qab kho, nrog 10 microFarad smoothing capacitor) rau ntau yam haujlwm.
