Kuv thiab kuv pab neeg tau teeb tsa los teeb lub levitate LED. Tom qab lub sijhawm luv luv googling ncig, Kuv tau hla cov vis dis aus los ntawm SparkFun Electronics, uas tuaj yeem pom ntawm no, uas peb ua raws li peb tsim tawm ntawm. Peb lub teeb levitates nrog ib lub tshuab hluav taws xob saum lub teeb. Peb xaiv qhov kev tsim no vim tias nws tsuas yog xav tau ib lub tshuab hluav taws xob los levitate LED. Txhawm rau ua tiav qhov hloov pauv hluav taws xob wireless peb tau siv lub hauv paus txuas txuas rau hauv qab ntawm lub tshuab hluav taws xob levitation thiab lub kauj thib ob txuas rau lub LED. Cov qauv LED muaj cov xim dawb LED, cov kauj thib ob, thiab cov hlau nplaum ruaj khov. Kuv tsim cov qauv thiab luam tawm 3D txhua qhov.

Kauj Ruam 1: Tsim Tus Qauv

Kuv siv Solidworks los tsim cov qauv. Lub hauv paus yog txhais tau tias yuav tsev luam tawm lub rooj tsav xwm hluav taws xob. Muaj cov qhov hla los ntawm lub hauv paus, ob txhais ceg, thiab cov ntu sab saum toj rau txoj hauv kev xov hlau. Peb tsis muaj sijhawm los luam tawm lub rooj tsav xwm hauv Circuit Circuit, yog li kev txiav tawm ntawm lub rooj tsavxwm tsis siv.

Kauj Ruam 2: Winding Electromagnet

Txhawm rau tshuab cua tshuab hluav taws xob, peb siv lub zog ntsuas kom tig lub ntsia liaj qhov rooj nrog lub tshuab ntxhua khaub ncaws ua qhov teeb meem. Peb tau mus qeeb heev kom ntseeg tau tias cov hlau tsis sib tshooj nws tus kheej. Ua nws li no tau siv sijhawm ntev. Kuv xav tias nws yuav zoo los txuag sijhawm ntau thiab tsis ceev faj nrog kev sib tshooj thaum cua. Peb kwv yees muaj 1500 tig hauv lub tshuab hluav taws xob.

Kauj Ruam 3: Cov Khoom Siv Hluav Taws Xob

Rau kev sim, peb siv qhov hloov pauv DC fais fab mov. Tom qab txhua yam tau ua haujlwm, Kuv siv lub qub 19V lub laptop them nyiaj thiab lub zog tswj hluav taws xob 12V kom muab lub zog rau 12V tsheb nqaj hlau. Kuv siv 5V tus tswj hwm los ntawm qhov tso tawm ntawm 12V tus tswj hwm los muab lub zog rau 5V kev tsheb nqaj hlau. Nws yog ib qho tseem ceeb heev los txuas tag nrho koj thaj chaw ua ke. Peb muaj teeb meem nrog peb cov circuits ua ntej peb ua qhov no. Peb siv cov khoom siv hluav taws xob hla 12V thiab 5V cov khoom siv hluav taws xob los txo cov suab nrov hauv cov kab hluav taws xob ntawm lub rooj tsavxwm.

Kauj Ruam 4: Kev Siv Hluav Taws Xob

Lub vojvoog levitation yog qhov nyuaj tshaj plaws ntawm txoj haujlwm no. Kev sib nqus levitation tau ua tiav siv lub suab ntsuas qhov ntsuas kom txiav txim siab nrug ntawm cov hlau nplaum ruaj khov mus rau lub tshuab hluav taws xob thiab sib piv Circuit kom hloov lub tshuab hluav taws xob qhib lossis tua. Raws li lub sensor tau txais lub zog sib nqus zoo dua lub sensor tso tawm qhov qis dua. Qhov ntsuas hluav taws xob no piv rau qhov ntsuas hluav taws xob tuaj ntawm lub hwj chim. Peb siv op-amp los sib piv ob qhov hluav taws xob. Cov zis ntawm op amp hloov tus N-channel mosfet rau lossis tawm kom tso cai tam sim no ntws los ntawm lub tshuab hluav taws xob. Thaum cov hlau nplaum ruaj khov (txuas rau LED) ze rau ntawm lub tshuab hluav taws xob, qhov uas nws yuav nqus mus rau lub tshuab hluav taws xob, lub tshuab hluav taws xob tua hluav taws, thiab thaum nws nyob deb dhau, qhov twg nws yuav poob tawm ntawm kev nce, lub tshuab hluav taws xob tig rau Thaum pom qhov sib npaug, lub tshuab hluav taws xob qhib thiab tawm sai heev, ntes thiab tso cov hlau nplaum, tso cai rau nws levitate. Lub potentiometer tuaj yeem siv los kho qhov kev ncua deb uas cov hlau nplaum yuav yuj.

Hauv lub vijtsam oscilloscope, koj tuaj yeem pom lub teeb liab los ntawm cov cuab yeej ua kom pom lub ntsej muag thiab cov hlau nplaum hloov pauv thiab tawm. Raws li lub LED tau los ze dua rau lub ntsuas cua, kab daj nce. Thaum cov hlau nplaum nyob ntawm kab ntsuab tsawg. Thaum nws tawm ntawm txoj kab ntsuab yog siab.

Nyob ntawm qhov ib puag ncig thiab yam koj siv ua lub tshuab tsim hluav taws xob, koj yuav xav tau ntxiv lub zog me me los ntawm lub ntsuas hluav taws xob tso rau hauv av. Qhov no yuav tso cai rau feem ntau ntawm cov suab nrov mus ncaj rau hauv av thiab lub teeb pom kev huv los ntawm lub ntsuas kom siv los ntawm op-amp.

Kauj Ruam 5: Wireless Circuit Circuit

Txhawm rau daws qhov hloov pauv lub zog hluav taws xob, peb qhwv thawj lub kauj ntawm 25 tig nrog 24 gauge hlau nplaum hlau nyob ib puag ncig tus tuav lub ntsuas. Peb tom qab ntawd ua cov theem thib ob los ntawm kev qhwv 32 gauge hlau nplaum hlau nyob ib ncig ntawm lub raj ntawv ntawm 25 kab. Thaum nws tau qhwv, peb swb lub kauj tawm ntawm daim ntawv thiab muab nws pauv mus rau ib qho LED. Nco ntsoov tshem cov xim txha hniav laus ntawm cov hlau nplaum hlau uas koj tab tom siv.

Peb siv lub tshuab hluav taws xob ib puag ncig ntawm 1 MHz hloov MOSFET rau thiab tawm uas tso cai rau tam sim no ntws los ntawm thawj kauj los ntawm 0 txog 12V ntawm 1 MHz. Rau kev sim, peb siv Analog Discovery rau lub tshuab hluav taws xob ua haujlwm. Qhov kawg tau siv lub 555 timer square wave generator Circuit los hloov MOSFET. Txawm li cas los xij, lub voj voog no tau tsim cov suab nrov uas cuam tshuam nrog txoj kab hluav taws xob. Kuv tau ua ib lub thawv ntawv txhuas txheej uas muaj qhov faib cais cais lub tshuab hluav taws xob thiab lub vojvoog levitation. Qhov no txo qis cov suab nrov.

Kauj Ruam 6: Sib dhos

Kuv siv Chroma Strand Labs ABS rau 3D luam tawm lub hauv paus thiab txhais ceg. Cov ceg ua rau ntau dhau thaum luam ntawv, yog li kuv rov luam nrog Chroma Strand Labs PETg. PETg warp tsawg heev. Txhua qhov ntu haum ua ke yam tsis siv kua nplaum. Peb yuav tsum tau txiav ob peb qhov thais hauv nws txhawm rau ntxiv kev tshem tawm rau cov xov hlau. Tej zaum koj yuav tsum tau xuab zeb nqes mus rau thaj chaw uas tiv tauj lwm daim kom tso cai kom haum.

Peb tab tom npaj kom tau txais lub rooj tsav xwm hluav taws xob luam tawm thiab muab cov khoom sib txuas rau nws kom nws txhua qhov haum rau sab hauv lub rooj tsav xwm txiav tawm.
