2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Hauv cov lus qhia no, peb tau ua lub roj teeb siv RGB LED lub voos xwmfab. Nws tau hloov pauv los ntawm cov xim nrog kev pab los ntawm kev tsim hauv microcontroler.

Hauv qab ib nrab ntawm lub voos xwmfab yog txiav laser thiab ib nrab sab saum toj yog 3D luam tawm. Lub voos xwmfab muaj lub laub khawm nyob rau sab xub ntiag thiab ntawm sab yog DC chim rau them. Sab hauv yog lub roj teeb uas suav nrog peb lub roj teeb li-ion ua kom lub zog 3W LED ntxiv rau ATTINY85 thiab lub tshuab tsav tsheb.

Lub hom phiaj ntawm lub teeb no yog qhov zoo nkauj ua ntej, tab sis tom qab thawj qhov kev sim nws muab tawm tias lub voos xwmfab tau teeb pom qhov tsaus ntuj zoo heev. Kuv yuav nco ntsoov ntim qhov no rau kuv qhov kev mus pw tom ntej thiab saib seb nws ua haujlwm zoo li cas.

Nco tseg: Txoj haujlwm no yog kev koom tes ntawm kuv thiab MatejHantabal. Nws tau ua qhov tsim feem ntau thiab kuv tau ua cov khoom siv hluav taws xob.

Kauj Ruam 1: Qhov Chaw

Rau qhov haujlwm no, koj yuav xav tau cov hauv qab no:

3W RGB lub hnub qub LED

digispark ATTINY85

TIAB SA 2803

BC327

3x 18650 roj teeb

tus tuav rau 3 18650 li-ion roj teeb

3x dub 12mm laub khawm

perfboard

PCB ntsia hlau terminals

3 x 1K resistors

qee cov txiv ntseej M4 thiab ntsia liaj qhov rooj

ob peb kab

Kwv yees kwv yees tus nqi: 40 €/45 $

Kauj Ruam 2: Cov Cuab Yeej

Rau txoj haujlwm no, koj yuav xav tau cov cuab yeej hauv qab no:

3D Tshuab Luam Ntawv - Qhov no yuav luam tawm sab saum toj ntawm lub voos xwmfab

Laser Cutter - Qhov no yuav txiav hauv qab ntawm lub voos xwmfab los ntawm plexiglass

Soldering Iron - Txhawm rau txuas cov khoom siv hluav taws xob

Rab Phom Kub Kub - Cov kua nplaum yuav tuav tag nrho cov khoom siv hluav taws xob thiab rooj plaub ua ke

Kauj Ruam 3: Luam Ntawv 3D

Ua ntej tshaj plaws, cia peb sau rau saum. Koj tuaj yeem siv txhua hom filament uas koj nyiam rau qhov no, tsuav lub teeb tuaj yeem hla dhau. Peb siv pob tshab PLA-D. Peb siv Prusa i3 MK2 los luam tawm ntu no. Cov ntawv luam tawm tau suav nrog hauv cov theem no.

Kauj Ruam 4: Txiav Qhov Case

Koj yuav tsum tau siv lub tshuab txiav laser los ua rooj plaub. Peb siv GCC SLS 80. Yog tias koj tsis muaj lub tshuab txiav laser muaj ntau qhov kev pabcuam hauv cheeb tsam, uas koj tuaj yeem muab cov duab vector no rau, thiab lawv yuav txiav nws rau koj rau tus nqi pheej yig. Koj tuaj yeem siv cov khoom siv rau qhov no. Peb txiav qhov no los ntawm acrylic tab sis txhua yam yuav ua haujlwm tau zoo thiab ua rau muaj kev sib xyaw ua ke nrog lub teeb. Txhua cov ntaub ntawv xav tau suav nrog hauv cov theem no.

Nco tseg: Cov ntaub ntawv no tau kos rau 3mm (1/8 ") cov khoom tuab. Nco ntsoov tias koj muaj cov tuab no

Kauj Ruam 5: Perf-board Circuit

Vim tias lub tshuab tsav tsheb rau lub voos xwmfab suav nrog ntau yam khoom siv hluav taws xob xws li transistors, resistors thiab ib qho kev sib txuas ua ke, Kuv txiav txim siab mus nrog lub vaj huam sib luag tsis siv breadboard lossis cov ntsia hlau. Koj tsuas yog yuav tsum tau txhuam tag nrho cov khoom tsim nyog ntawm lub perfboard raws li cov phiaj xwm suav nrog. Kuv siv PCB cov ntsia hlau txuas txuas lub rooj tsavxwm rau lub roj teeb thiab rau RGB LED.

Kauj ruam 6: Lub zog

Vim tias peb siv 3W RGB LED uas kos ib puag ncig 0.7A ntawm lub zog tag nrho peb xav tau cov roj teeb muaj zog zoo los ua lub zog ntaus ntawv no. Peb txiav txim siab siv peb lub 18650 3.7 2600 mAh li-ion roj teeb. Lawv hnyav dua me ntsis thiab loj dua li-po roj teeb tab sis lawv kuj pheej yig me ntsis kom haum rau hauv rooj plaub ib yam. Koj yuav tsum tau ua lub roj teeb pob. Qhov kev xaiv zoo tshaj plaws yog siv lub tshuab roj teeb pom kev tab sis txij li lawv zoo nkauj heev peb tau txiav txim siab tsuas yog lo peb 18650 tus neeg tuav roj teeb ua ke thiab txuas lawv ua ke. Peb siv 5.5/2.1mm DC chim li them txuas tab sis koj tuaj yeem siv lwm qhov txuas. Tsuas yog nco ntsoov tias lub adapter uas koj yuav tau ntsaws rau hauv qhov txuas no yuav tsum muaj 5V 2A tso tawm.

Tam sim no cia ua qee qhov lej yooj yim. Lub peev xwm ntim roj teeb tag nrho yuav tsum nyob ib puag ncig 7800 mAh. Muaj qhov hloov pauv hloov hluav taws xob ntawm qhov tso tawm ntawm lub roj teeb pob uas ua peb zaug tso zis hluav taws xob los ntawm 4V txog 12V. Qhov hloov pauv hluav taws xob no yuav tsum txo qis lub roj teeb pob ntau tshaj tawm tam sim no mus rau 2600 mAh. Tam sim no, kev sib tw kos ib puag ncig 700 mA thiab 2600 mAh faib los ntawm 700 mA yog 3, 7. Qhov ntawd ua rau peb lub roj teeb tag nrho nyob ib puag ncig 3 thiab 3/4 teev. Tab sis nco ntsoov tias qhov no ua haujlwm tsuas yog hauv kev tshawb xav thiab lub roj teeb tiag tiag tsuas yog ncig 3 teev. Lub roj teeb pob yuav tsum tau them rov qab txog 3 teev. Koj tseem tuaj yeem txuas nws txuas nrog lub zog thiab tsis muaj lub roj teeb siv.

Kauj ruam 7: Code

Nov yog tus lej rau Attiny85. Koj tuaj yeem tso nws siv Arduino IDE.

Kauj Ruam 8: Muab Nws Txhua Qhov Ua Ke

Npaj hauv qab ntawm lub thawv npaj, thiab peb tuaj yeem pib tso cov khoom siv hluav taws xob sab hauv. Peb muab cov roj teeb Li-ION tso rau hauv qab heev. Tau kawg koj tuaj yeem tso cov khoom nyob txhua qhov chaw koj xav tau, tab sis qhov no ua haujlwm zoo tshaj plaws rau peb. Tam sim no pib muab ob sab tso rau hauv lawv qhov chaw. Muab lub pob rau sab xub ntiag thiab DC chim rau sab. Koj tuaj yeem pib muab cov kua nplaum kub tso rau sab hauv los tuav ob sab thiab roj teeb nyob rau hauv.

Kauj ruam 9: Ua tau

Yog li ntawd koj muaj nws, nqa tau, muaj ntau yam thiab muaj kuab heev RGB teeb. Yog tias koj ua raws txhua qib, koj yuav tsum tau ua nws tam sim no. Yog tias koj muaj lus nug lossis lus pom zoo, peb yuav zoo siab tau hnov lawv hauv kab lus hauv qab no. Txaus siab rau!

Yog tias koj nyiam cov lus qhia no, thov pov npav rau nws hauv Kev Ua Nws Glow Contest. Ua tsaug.
