Thaum koj tau sau txhua yam koj xav tau, koj tuaj yeem ua raws cov theem hauv qab no kom pib sib sau ua ke koj tus kheej UV tshuaj tua kab mob:

Kauj Ruam 1: Rub tawm thiab Luam Cov Phiaj Xwm

Txoj haujlwm no suav nrog 3 cais Cov Ntawv Luam Circuit Court (PCBs) uas tau tsim los siv KiCAD thiab luam tawm siv BotFactory's SV2 hauv HomeLab. PCB hauv plawv ntawm qhov kev tsim qauv no tsis tsuas yog txuas lub zog, pib khawm, 7-ntu tso saib, thiab LEDs, tab sis nws kuj tseem nyob hauv 'lub hlwb' uas tswj hwm lub cuab yeej. Txawm hais tias peb lub rooj sib tham tam sim no txuas nrog cov xov hlau hloov pauv tau, nws tuaj yeem rov tsim nws siv cov PCBs hloov pauv tau!

Lub rooj tsavxwm tseem ceeb yuav suav nrog ATTINY85, thaum ob qho ntxiv yuav muaj ob lub UV LEDs. Kev tsim qauv tag nrho yog siv los ntawm 9V 2A chim lub qhov ncauj, rau qhov AC adapters muaj dav.

Luam peb lub laug cam thiab txiav lawv kom haum rau qhov loj me. Koj tuaj yeem siv cov ntaub ntawv peb tau muab hauv cov kauj ruam no! Txij li thaum peb tsis tuaj yeem tso cov ntaub ntawv rau pawg thawj coj ntawm no, koj tuaj yeem rub tawm lawv dawb los ntawm BotFactory lub vev xaib tam sim no. Thaum luam tawm, siv lub ntsuas ntsuas kom ntseeg tau tias tsis muaj luv lossis tawg ib qho. Yog tias koj tsis muaj lub multimeter ces kev tshuaj xyuas qhov muag yuav txaus.

Kauj ruam 2: Rub tawm thiab Luam Tawm Cov Ntaub Ntawv

Peb tau siv Autodesk Fusion 360 los tsim lub clamshell enclosure, thiab luam tawm rooj plaub siv peb tus kheej 3D Tshuab Luam Ntawv. Siv cov ntaub ntawv.stl uas tau muab hauv qib no luam tawm tib lub thawv rau tsev rau koj cov khoom siv hluav taws xob. Lub qhov rau lub khawm tau ua los ntawm tus kheej siv lub zog laum thiab 8mm laum ntsis, tab sis tuaj yeem yooj yim ntxiv siv CAD software ua ntej luam ntawv. Yog tias koj tab tom ua lub qhov, nws yuav tsum tau muab tso rau ntawm sab xis raws li cim los ntawm xub xub xiav hauv daim duab thib peb. Nco ntsoov kom loj thiab kho qhov qhib raws li qhov ntev ntawm koj cov khoom.

Sib dhos pob khawm ntawm lub thawv los ntawm kev tso ib nrab ntawm clamshell ua ke thiab xov nws siv 1.75mm 3D luam ntawv filament, lossis tus pas me me ntawm qhov ntev sib xws. Xyuas kom lub qhov rooj qhib tau thiab kaw yam tsis muaj teeb meem.

Kauj Ruam 3: Sib Sau Cov Tshuaj Ntxhua Khaub Ncaws

Thaum tag nrho koj cov khoom luam tawm, koj tuaj yeem pib sib sau ua UV tshuaj ntxuav tes. Pib los ntawm kev siv tag nrho cov khoom siv rau hauv lawv qhov chaw tshwj xeeb ntawm cov laug cam. Peb siv cov ntsuas kub kub ruaj khov tsis kub, uas peb rov ua kom sov li 150 ℃. Peb siv rab phom rov qab los rau qhov xub pib tso tag nrho cov khoom me me, thiab tom qab ntawd rov ua kom tag nrho ntawm lub rooj tsavxwm ntawm lub tshav kub ntawm SV2 kom ntseeg tau tias cov khoom siv nrog cov pawm loj, xws li cov transistors, rov ua kom raug. Peb tau muab cov phiaj xwm siv thiab teeb tsa kom koj tuaj yeem pom dab tsi mus qhov twg. Cov duab saum toj no kuj tseem tuaj yeem siv ua qhov zoo siv.

Kauj Ruam 4: Ua Haujlwm ATTINY85

Program ATTINY85 siv Sparkfun Tiny AVR Programmer thiab Arduino IDE. Peb tau muab cov cai rau program ATTINY85 hauv qab no. Koj tuaj yeem txuas rau nws ntawm 6-tus pin header, raws li tau hais tseg hauv Sparkfun's Tiny AVR Programmer Hookup Guide.

Lub microcontroller tos rau cov neeg siv tswv yim ntawm lub laub-khawm. Thaum nws pom cov lus tawm tswv yim, nws xa lub teeb liab mus rau ob lub zog hluav taws xob ua haujlwm siab transistors, tig rau 4 UV LEDs. Nyob rau tib lub sijhawm, suav suav suav yog pib los ntawm microcontroller. Qhov 7-ntu tso saib qhia pom pes tsawg vib nas this. Thaum lub sijhawm teem mus txog 0, LEDs tua, tso cai rau tus neeg siv qhib lub clamshell enclosure thiab khaws cov khoom huv.

Txuas 7-ntu cov zaub thiab UV LEDs cov laug cam siv cov xov hluav taws xob txuas rau tus pin txuas. Cov LEDs yuav ci thaum lub khawm qhib/tua raug nias yog tias ATTINY85 tau ua haujlwm tau zoo thiab txuas nrog.

Kauj Ruam 5: Ntxig Cov Txheej Txheem Kub-Teeb

Teem lub qhov thaiv los ntawm kev tso cov cua sov teeb teeb. Muab 3mm tso rau hauv ob lub qhov ntawm cov hauv qab clamshell, hauv qab qhov uas daim npog ntsej muag yuav mus. Nias lawv mus rau hauv qhov chaw nrog cov hlau txuas ntawm 250 ℃. Cov ntxig yuav tsum tau muab tso me ntsis hauv qab lub ntug ntawm lub qhov. Ua kom ntseeg tau tias cov ntxig ua haujlwm los ntawm ntsia hlau rau ntawm lub ntsej muag raws li qhov ntsuas haum. Lub timer zaub yuav nyob hauv qab lub ntsej muag.

Kauj Ruam 6: Muab Cov Khoom Siv Hluav Taws Xob

Muab lub rooj tsavxwm tseem ceeb tso rau sab xis ntawm daim thaiv, qhov twg yuav muaj daim npog ntsej muag. Txuas lub pob thiab ntxig nws hla lub qhov ntawm sab. Qhov no yuav tsum yog lub qhov rau khawm uas koj tau ua lossis ntxiv siv cov ntaub ntawv CAD muab. Txuas cov xov hlau sab hauv raws li tau teev tseg hauv kab lus.

Kauj Ruam 7: Muab UV Boards

UV LED cov laug cam yuav raug muab tso rau hauv lawv qhov sib txawv ntawm sab hauv ntawm sab saum toj thiab hauv qab lub plhaub ntawm lub thawv ntawv. Qhov no yuav yog nyob rau hauv cov duab plaub extrusions. Xa mus rau daim duab saum toj no rau kev qhia kom raug ntawm pawg thawj coj. Pib los ntawm kev thov ob qho me me ntawm cov kua nplaum super ntawm txhua qhov kawg ntawm sab nraum qab ntawm PCB thiab tom qab ntawd ntxig lawv sai. Nias maj mam ua kom lawv nyob hauv qhov chaw thiab tso cov kua nplaum kom qhuav.

Kauj Ruam 8: Lub Hwj Chim Loj

Txuas ob lub laug cam mus rau lub rooj tsav xwm loj uas siv cov xov hlau hla los ntawm sab hauv ntawm daim thaiv. Muaj qhov qhib rau cov xov hlau hla mus. Pawg thawj coj ntawm lub plhaub sab saum toj yuav muaj nws cov xov hlau hla los ntawm lub qhov ntawm sab thiab rov qab mus rau hauv lub qhov me me nyob rau sab ntawm lub plhaub hauv qab. Qhov loj dua ntawm sab yuav raug siv los txhawb lub rooj tsav xwm loj.

Siv lub thoob me me txuas txuas hlau txhawm rau muab lub zog rau lub rooj tsav xwm loj. Ua qhov no los ntawm kev txuas koj 9V AC/DC fais fab mov rau lub tog raj txuas. Thaum txhua yam tau txuas nrog kom raug, ntsia hlau rau ntawm lub ntsej muag.

Kauj Ruam 9: Muab Cov iav

Ib qho iav me me tau siv los xyuas kom cov khoom tsis kov PCB hauv qab yog li nws tuaj yeem raug tshuaj kom raug. Cov iav no yuav muab tso rau hauv txoj kab uas hla siab dua hauv qab plhaub kom nws tsis txhob kov hauv qab PCB. Ruaj lub iav siv plaub qhov me me ntawm cov kua nplaum super ntawm txhua lub ces kaum thiab tom qab ntawd muab nws tso rau hauv qhov nrawm. Maj mam nias ntawm cov ces kaum thiab tso cov kua nplaum kom qhuav.

Kauj Ruam 10: Kuaj Cov Tshuaj Ntxhua Khaub Ncaws

Kuaj koj lub tshuaj ntxuav tes kom paub tseeb tias nws ua haujlwm tau zoo. Muab ib yam khoom tso rau hauv lub tshuaj ntxuav tes thiab kaw lub hau. Thaum koj nias lub pob, suav suav yuav tsum pib los ntawm 300 vib nas this thiab tom qab ntawv tua. Thaum koj tau ua kom ntseeg tau tias koj lub tshuaj ntxuav UV tau ua haujlwm tiav, siv raws li xav tau! Koj tuaj yeem nyeem ntxiv txog yuav ua li cas thiab vim li cas peb thiaj tsim cov tshuaj ntxhua khaub ncaws ntawm peb UV Sanitizer Design blog ncej.

[Nco ntsoov ua raws li kev tiv thaiv kev nyab xeeb thaum tsim cov cuab yeej no. Thov nco ntsoov tias kev siv tsis raug thiab raug UV lub teeb tuaj yeem ua rau muaj kev phom sij rau koj thiab lwm tus. Thov siv koj li tshuaj ntxuav tes kom raug thiab ua lub luag haujlwm.]
