Siv cov xov hluav taws xob, Velostat thiab neoprene, xaws koj tus kheej cov ntaub khoov kho qhov muag. Cov khoov khoov no ua rau muaj kev cuam tshuam (txo qis hauv kev ua haujlwm) rau siab, tsis tshwj xeeb rau khoov. Tab sis vim tias nws tau sib xyaw ntawm ob txheej ntawm neoprene (cov ntaub ruaj khov), lub siab tau ua thaum khoov, yog li tso cai rau ib qho ntsuas ntsuas (kaum sab xis) ntawm kev siab. Ua siab zoo? Saib hauv qab no: Yog li ntawd koj tuaj yeem siv feem ntau qhov ntsuas siab ntsuas ntsuas khoov, tab sis qhov no kuv pom muab rau kuv qhov txiaj ntsig zoo tshaj plaws (rhiab heev) rau ntsuas qhov khoov ntawm tib neeg pob qij txha thaum txuas rau lub cev. Nws yog qhov rhiab txaus rau sau npe txawm tias khoov me ntsis thiab muaj qhov loj txaus kom tseem tau txais cov ntaub ntawv thaum cov ceg tawv tau khoov tag. Qhov ua haujlwm tsis txaus ntawm qhov khoov kho qhov muag no nyob ntawm qhov pib siab. Qhov zoo tshaj koj muaj siab dua 2M ohm tiv thaiv ntawm ob qho kev sib cuag thaum lub ntsuas cua dag ncaj thiab tsis txuas nrog. Tab sis qhov no tuaj yeem sib txawv, nyob ntawm seb lub sensor tau xaws thiab loj npaum li cas ntawm kev sib tshooj ntawm cov nplaim hluav taws uas nyob ib sab. Qhov no yog vim li cas kuv xaiv los xaws cov neeg sib txuas ua kab pheeb ces kaum ntawm cov xov hluav taws xob - kom txo qis kev sib tshooj ntawm cov nplaim hluav taws xob. Tab sis tsuas yog khoov me ntsis lossis kov ntawm tus ntiv tes feem ntau yuav ua rau qhov kev tiv thaiv qis mus rau ob peb Kilo ohm thiab, thaum muaj kev nyuaj siab, nws nqis mus txog 200 ohm. Lub sensor tseem pom qhov sib txawv, sab xis mus txog qhov nyuaj li koj tuaj yeem nias nrog koj cov ntiv tes. Qhov ntau yam tsis yog-kab thiab tau txais me dua li qhov tsis kam txo qis. Qhov ntsuas no yog qhov yooj yim heev, ua tau yooj yim thiab pheej yig piv rau kev yuav ib qho. Kuv kuj tseem pom tias nws ntseeg tau txaus rau kuv cov kev xav tau. Kuv tseem muag cov ntaub xuas tes xaws khoov ntawm Etsy.

Kauj ruam 2: Ua tus Stencil

Vim tias peb tab tom ua khoov khoov nws ua rau nws nkag siab kom ntev nws thiaj tuaj yeem txuas tau yooj yim mus rau qhov twg khoov yuav tsum ntsuas.

Koj tsis tas yuav ua raws cov duab thiab qhov loj me rau lub ntsuas qhov tseeb. Kuv tau khaws nws yooj yim los tham txog lub tswv yim. Tsim ib qho stencil uas suav nrog kos rau cov xaws uas yuav tsum khiav kab pheeb ces kaum. Nws yog qhov zoo kom tso tsawg kawg 5mm qhov chaw nruab nrab ntawm cov xaum thiab cov ntug ntawm neoprene. Cia 1cm qhov chaw nruab nrab ntawm cov xaws. Nws yog hais txog TSIS tsim lub ntsej muag ua haujlwm dhau, yog li lub sensor nyob qis qis. 4-7 kab xev kab xev (nyob ntawm qhov ntev ntawm koj lub ntsuas) zoo ib yam. Tsis tas li, lawv tsis tas yuav tsum ntev. 1, 5cm qhov siab Rau cov ntawv no koj yuav xav tawm thaj tsam li 1-2 cm ntawm txhua qhov kawg ntawm lub ntsuas kom koj tuaj yeem txuas tus popper, uas yuav muaj txiaj ntsig zoo rau txuas nws mus rau hauv cov ntaub npuag tom qab.

Kauj Ruam 3: Npaj Cov Khoom

Thaum koj tau tsim lub stencil, taug qab nws mus rau neoprene kom koj muaj ob daim IDENTICAL (tsis yog mirrored) daim. Ua haujlwm cuam tshuam, fuse ib daim me me ntawm cov ntaub ua kom ncab (saib duab) mus rau qhov kawg ntawm txhua daim ntawm neoprene. Ntawm ib thooj nws yuav tsum yog sab ntsuab (sab hauv) thiab sab nraud ntawm sab grey (sab nraum). Qhov no yog li ntawd tom qab ntawd, thaum lub ntsuas pa tau xaws ua ke, cov ntaub ua hluav taws xob tsuas yog ntsib ib sab (qhov no ntau dua rau qhov laj thawj zoo nkauj, yog li nws tseem yuav ua haujlwm tsis hais qhov twg koj fuse cov ntaub ua kom zoo).

Kauj Ruam 4: Xaws

Tam sim no uas ob sab ntawm koj lub sensor tau npaj, xov ib rab koob nrog qhov zoo ntawm cov xov hluav taws xob. Koj tuaj yeem nqa nws ob lossis ib leeg. Kuv nyiam coj nws ib leeg.

Xaws rau hauv neoprene los ntawm sab nraub qaum/sab nraum (hauv qhov no yog sab grey). Pib ntawm qhov kawg deb deb ntawm thaj ntawm cov ntaub ua hluav taws xob. Plooj rov qab thiab tawm mus raws li qhia hauv cov duab. Thaum koj mus txog qhov kawg, xaws cov xov rau cov ntaub ua hluav taws xob. Ua yam tsawg kawg 6 txoj hlua los txuas ob. Ua qhov xaws no rau ob daim ntawm neoprene, tshwj tsis yog tias ib zaug cov ntaub ntawv siv tau yog nyob rau lwm sab ntawm cov khoom siv xaws. Tseem koj xav txuas cov xov hluav taws xob mus rau cov ntaub npog uas muaj tsawg kawg 6 txoj hlua. Yog vim li cas qhov kev xaws ntawm ob sab yuav tsum zoo ib yam yog li ntawd thaum lawv pw saum ib leeg (ntsib ib leeg) cov hlua sib tsoo hla thiab sib tshooj hauv ib qho. Qhov no muaj ob qhov zoo. Ua ntej ntawd nws tsis zoo li tias cov hlua yuav tsis ua kab thiab tsis ua ib qho kev sib txuas sib tshooj. Thiab qhov thib ob tias qhov kev sib txuas saum npoo tsis loj heev. Kuv tau pom tias yog tias cov nplaim hluav taws xob loj dhau uas qhov kev nkag siab ntawm lub ntsuas hluav taws xob tsis zoo rau qhov kuv xav tau.

Kauj ruam 5: Kaw lub Sensor

Ua ntej kaw lub ntsuas koj yuav xav txiav tawm ib qho ntawm Velostat uas tsuas yog me me me dua li koj daim neoprene. Daim Velostat no yuav nyob nruab nrab ntawm koj ob txoj hlua ua haujlwm. Thiab qhov no yog dab tsi tsim lub siab hloov pauv hauv kev ua haujlwm. Velostat tso hluav taws xob ntau dhau, nyuab dua koj nias ob txheej txheej ua ke, nrog Velostat nyob nruab nrab. Kuv tsis paub tseeb tias yog vim li cas qhov no, tab sis kuv xav tias nws yog vim muaj cov pa roj carbon particle hauv Velostat uas ua hluav taws xob thiab muaj kev kub siab ntau ntxiv rau lawv kom lawv los ze zog ua ke thiab ua tau zoo dua lossis zoo ib yam (???) Yog li, tso daim Velostat nyob nruab nrab thiab xaws lub sensor ua ke raws li qhia hauv daim duab. Tsis txhob xaws nruj heev, txwv tsis pub koj yuav muaj qhov pib qhov siab uas yuav ua rau koj lub sensor tsis nkag siab.

Kauj Ruam 6: Poppers

Nyeem cov lus qhia uas tuaj nrog koj lub tshuab popper. Kuv tau txuas ob lub poppers sib txawv (poj niam thiab txiv neej) rau ob sab ntawm kuv lub sensor, tab sis qhov no yog nyob ntawm koj. Kuv tau txuas rau sab xub ntiag ntawm txhua tus popper (ntu popper) rau sab nrog lub thaj ntawm cov ntaub ua kom zoo, yog li ob qho tib si poppers txuas ntawm tib sab.

Yog tias koj ua yuam kev nrog poppers, cov cuab yeej zoo tshaj plaws los thim lawv yog ib rab phom thiab nyem ua ke ib feem tsis muaj zog, uas ib txwm yog sab nraub qaum (feem ntau tsuas yog lub nplhaib). Thiab tom qab ntawd fiddle kom txog thaum nws los xoob. Qhov no feem ntau puas cov ntaub tab sis.

Kauj Ruam 7: Kev ntsuas Multimeter

Tam sim no koj lub sensor tiav lawm! Nqe ob qho kawg mus rau lub ntsuas cua thiab teeb nws los ntsuas qhov tsis kam. Txhua lub ntsuas yuav muaj qhov sib txawv ntawm kev tiv thaiv tab sis tsuav nws tsis me me thiab ua haujlwm rau koj lub hom phiaj, txhua yam zoo. Lub sensor kuv ua tau muaj cov hauv qab no: Dag tiaj: 240 K Ohm Nias nrog ntiv tes: 1 K Ohm Dag ntawm sab: 400 K Ohm Bent: 1, 5 K Ohm

Kauj Ruam 8: Kev Pom Duab Software

Txhawm rau pom kev hloov pauv hauv kev tiv thaiv hauv qhov khoov koj tau ua koj tseem tuaj yeem txuas nws mus rau koj lub khoos phis tawj ntawm lub microcontroller (Arduino) thiab siv me ntsis ntawm cov lej (Ua) kom pom nws. Txog Arduino microcontroller code thiab Ua kom pom kev pom tus lej thov saib ntawm no >> https://www.kobakant.at/DIY/?cat=347 Saib cov kab txiv kab ntxwv hauv cov duab. Nws nyob ntawm sab xis ntawm lub computer screen li cas thaum lub dab teg khoov. Thiab ntawm sab laug heev thaum lub dab teg ncaj !! Muaj kev lom zem thiab ua tsaug rau kev nyeem ntawv. Qhia rau kuv paub koj xav li cas.
