- Muab lwm tus xaim txuas rau sab zoo ntawm LED (qhov no yuav yog ib qho kev sojntsuam).
- Siv lub xaim txuas mus rau lwm qhov kawg ntawm tus tiv thaiv (qhov no yuav yog lwm qhov kev sojntsuam).
- Thaum kawg tau xaim xov hlau rau tus emitter ntawm transistor.
Kauj Ruam 3: Xeem Lub Circuit Court
Tam sim no koj muaj lub Circuit Court nws yog lub sijhawm los sim nws!
Cov khoom siv rau theem no:
- CR2032 roj teeb
- Lub voj voog
- Daim kab xev
Lub Circuit Court ua haujlwm li cas?
Yam koj nyuam qhuav tau ua yog lub ntsuas dej yooj yim. Lub transistor ua raws li kev hloov pauv. Thaum twg cov kws tshawb fawb sib cuag nrog dej, tam sim no yuav ntws los ntawm cov neeg soj ntsuam. Qhov no ua rau lub transistor. Thaum lub transistor tau tshwm sim, tam sim no yuav ntws los ntawm LED ua rau nws tso tawm lub teeb.
Cov kauj ruam:
- Siv daim kab xev los txuas cov xaim dawb (GND) rau sab tsis zoo ntawm lub roj teeb.
- Siv lwm daim kab xev txuas rau xaim liab (VCC) mus rau sab zoo ntawm lub roj teeb.
- Nqa ib khob dej thiab sau nws nrog dej. Muab ob qho kev soj ntsuam tso rau hauv dej.
- LOS YOG Txuas ob qhov kev soj ntsuam ua ke
LED yuav tsum teeb. Yog tias qhov no tsis yog ua kom ntseeg tau tias lub Circuit Court ua tau raws li cov hauv qab no:
- Lub roj teeb tsis tas
- Lub transistor yog txuas kom raug
- LED txuas nrog kom raug
- LED tsis muaj teeb meem
- Lub transistor tsis ua yuam kev
- Cov xov hlau tsis tawg
Kauj Ruam 4: 3D Luam Ntawv Hlua Tes
Yog tias koj tau txais lub voj voog npaj nws yog lub sijhawm los luam 3D lub casing!
Cov khoom siv rau theem no:
- 3D tshuab luam ntawv
- Mos PLA filament
Cov chaw luam ntawv:
- Ender 3: kuv
- 1.75mm Mos PLA
- 20% ntxiv
- Tsis muaj kev txhawb nqa
- Tsis muaj lub nkoj
- Nozzle kub = 200 ° C
- Lub txaj sov = 60 ° C
Rub tawm cov ntawv STL thiab pib luam tawm ob qho tib si.
Kauj Ruam 5: Tsim Sab Saum Toj
Hauv theem no peb yuav ua ob qhov kev sojntsuam txuas ntxiv.
Cov khoom siv rau theem no:
- M3 cev
- Hacksaw
- 3D luam tawm sab saum toj (saib cov kauj ruam dhau los)
Peb pib tawm nrog tus ntsia liaj qhov rooj uas peb yuav txiav ua ob qho tib si. Cov ntawv no yuav yog qhov kev sojntsuam txuas ntxiv.
Cov kauj ruam:
- Nqa M3 ntsia liaj qhov rooj thiab kos ob daim ntawm 1cm txhua.
- Siv koj hacksaw thiab txiav tus ntsia liaj qhov rooj ntawm cov cim.
- Lob cov ntawv luam tawm 3D sab saum toj thiab tso ob daim ntawm cov ntsia liaj qhov rooj rau hauv lub qhov ntawm sab laug thiab sab xis.
Tam sim no peb tau npaj los tso txhua yam tseg
Kauj Ruam 6: Tso & Rwb thaiv tsev Circuit Court
Hauv cov kauj ruam no peb yuav muab txhua yam tso rau hauv.
Cov khoom siv rau theem no:
- Lub voj voog
- CR2032 roj teeb
- 3D luam ntawv kauj -toog npab
- 3D luam tawm sab saum toj
- Aluminium daim kab xev
- Daim kab xev
- Soldering hlau & solder
- Kub kua nplaum phom
Cov kauj ruam rau tso lub Circuit Court:
- Nqa ib daim kab xev txhuas thiab txiav tawm ib puag ncig daim loj ntawm CR2032 roj teeb.
- Lob lub voj voos thiab siv daim kab xev puag ncig daim kab xev kom ruaj ntseg liab VCC xaim nyob hauv cov roj teeb ntawm cov hlua tes. (duab 1)
- Muab ob qho tshuaj ntsuam rau qhov txuas txuas ntxiv uas peb tau ua hauv cov kauj ruam dhau los. (duab 2)
- Coj tus LED thiab muab tso rau hauv lub qhov ntawm sab saum toj. (duab 4)
- Lob CR2032 roj teeb thiab muab tso rau saum daim kab xev txhuas. Xyuas kom tseeb tias qhov tsis zoo ntawm lub roj teeb tau ntsib koj.
- Siv qee daim kab xev los txuas cov xov hlau dawb (GND) nrog rau sab tsis zoo ntawm lub roj teeb. Npog lub roj teeb ntau npaum li koj tuaj yeem ua tau.
Rwb thaiv tsev Circuit Court
Lub voj voog yuav sib cuag nrog dej txhua lub sijhawm. Ib qho tseem ceeb yog qhov Circuit Court yuav tsum muaj peev xwm tiv taus dej, QHOV dej. Peb tab tom yuav siv rab phom kub kub los nplaum txhua qhov kev sib txuas. Qhov no yuav tiv thaiv ib qho kev luv luv.
Cov kauj ruam rau Rwb thaiv tsev ntawm Circuit:
- Nqa koj rab phom kub kub thiab lo ob txhais ceg ntawm LED. Xyuas kom txhua yam raug them tag nrho.
- Siv rab yaj phom los npog lub transistor thiab tus tiv thaiv.
- Siv rab phom nplaum los npog cov neeg soj ntsuam. (Tsis yog qhov kev sojntsuam txuas ntxiv rau saum)
Kuv tsis tau insulate qhov kev soj ntsuam tab sis nws zoo dua los ua li ntawd. Thaum twg los tau cov dej hauv lub tsev cov neeg sojntsuam yuav ntes cov dej. Qhov no yuav ua rau muaj LED uas niaj hnub tso lub teeb txawm tias thaum tsis muaj dej nyob ntawm qhov kev sojntsuam txuas ntxiv.
Kauj Ruam 7: Ua kom tiav txoj hlua tes
Peb yuav luag tiav! Tib qho uas peb yuav tsum ua yog muab txhua yam tso rau hauv vaj tsev. Tom qab koj tau ua tiav qhov koj tuaj yeem xaiv xaiv lo rau sab saum toj thiab qhwv tes ua ke lossis khaws nws zoo ib yam li nws yog
Cov khoom siv rau theem no:
Dej
Thaum twg qhov kev sojntsuam txuas ntxiv ua rau muaj kev sib cuag nrog txhua yam kev coj ua LED yuav ci. Raws li koj tuaj yeem pom kuv cov ntiv tes tau ua qee yam. Qhov no feem ntau yuav yog los ntawm hws.
Koj txoj hlua tes thaum kawg ua tiav! Qhia tawm rau koj cov phooj ywg lossis siv nws kom pom kev thaum ua luam dej lossis thaum muaj cua daj cua dub.
Kuv vam tias koj txaus siab rau Kuv Cov Lus Qhia thiab kuv yuav ntsib koj tom ntej!
