Lub moos no siv kev cai tsim 4-tus lej 7-ntu zaub ua los ntawm UV LEDs. Nyob rau sab xub ntiag ntawm lub vijtsam tso lub vijtsam uas muaj cov phosphorescent ("ci-hauv-qhov-tsaus") lossis cov khoom siv duab. Ib lub laub khawm nyob rau sab saum toj teeb UV teeb uas tom qab ntawd teeb lub vijtsam rau ob peb feeb kom nws pib ci lossis hloov xim uas tom qab ntawd maj mam ploj mus.

Txoj haujlwm no tau tshoov siab los ntawm qhov txaus ntshai Glow-In-The-Dark Plot Clock los ntawm Tucker Shannon. Thaum kuv rov kho nws qhov haujlwm kuv muab nws me ntsis los ntawm kev hloov lub ntsej muag ci-hauv-qhov-tsaus nrog ib qho 3D luam tawm los ntawm photochromic filament uas hloov xim thaum raug rau lub teeb UV. Lub sijhawm ntawd kuv pom tias lwm tus neeg muaj tib lub tswv yim (saib piv txwv ntawm no). Txawm hais tias cov cuab yeej siv phiaj xwm txheej txheem ntawm lub moos yog qhov txaus txaus nws muaj qhov tsis zoo uas cov lej tau tawm los nkhaus me ntsis yog li kuv tau xav txog lwm txoj hauv kev kom cov lej zoo dua. Thaum xub thawj kuv tau sim hloov lub teeb pom kev ntawm lub vijtsam LCD nrog UV LEDs thiab tom qab ntawd muab lub vijtsam duab/ci-hauv-qhov-tsaus nti tso rau saum. Txawm li cas los xij, nws tau muab tawm tias qhov kev sib kis kis tau los ntawm LCD tau qis heev. Tom qab ntawd kuv txiav txim siab los tsim 4-lej 7-ntu zaub siv UV LEDs los teeb lub vijtsam uas muab cov txiaj ntsig tau zoo dua.

Kauj Ruam 1: Luam Ntawv 3D

Cov ntaub ntawv stl hauv qab no yuav tsum luam tawm 3D. Cov tsev nyob tau luam tawm los ntawm PLA dub thaum rau 4digits.stl cov ntaub ntawv Kuv siv PLA dawb. Lub vijtsam tau luam tawm los ntawm violet UV xim hloov filament. Cov laug cam tuaj yeem luam tawm los ntawm ib qho khoom siv.

Kauj Ruam 2: Desoldering 7-ntu Zaub

Tom ntej no kuv txiav tawm ib daim los ntawm cov qauv PCB rau UV LEDs thiab cim cov chaw uas kuv xav tso cov LEDs raws li cov laug cam. Hauv qab hauv qab kuv tom qab txuas tus txiv neej lub taub hau rau txuas rau I2C lub hnab ev ntawv.

Kauj Ruam 4: Soldering LEDs thiab Pin Headers

Ntxiv mus, LEDs tau xaim raws li cov txheej txheem txuas uas luam theej tawm cov txheej txheem ntawm 4-tus lej zaub uas tau desoldered los ntawm I2C rov qab pob. Txog kev sib txuas ntawm cov tib neeg ntawm ib tus lej Kuv tau siv cov tooj liab tooj liab tooj liab thaum lwm qhov kev sib txuas tau ua nrog cov hlau sib cais. Txhua yam zoo li tsis zoo li qhov kawg.

Tom ntej no, Kuv txuas tus qauv PCB mus rau I2C lub hnab ev ntawv. Thaum kuv soldered ob ntu ncaj qha ua ke nws yuav tau ntse siv poj niam lub taub hau ntawm lub hnab ev ntawv kom ob tog tuaj yeem ntsaws thiab tsis ntsaws.

Txog kev sim kuv txuas nrog rov qab mus rau arduino nano thiab tso TM167test piv txwv los ntawm TM1637 lub tsev qiv ntawv.

Kauj Ruam 7: Ua tiav 4-tus lej Zaub

Tom ntej no 3D luam tawm 4digits.stl ib feem tau txuas rau saum cov LEDs. Txhawm rau nthuav lub teeb ntawm LEDs kuv tau ntim cov ntu nrog cov kua nplaum kub thiab kaw lawv nrog kab xev Kapton kom txog thaum cov kua nplaum tau tawv. Qhov no tshuav kuv nrog kev cai zoo 4-tus lej 7-ntu zaub.

Kauj Ruam 8: Glow-in-the-Dark Screen

Thaum xub thawj kuv tau sim kuj luam 3D lub vijtsam no los ntawm Glow-in-the-Dark filament. Txawm li cas los xij, nws muab tawm tias nws nthuav lub teeb ntau dhau, yog li cov lej zoo li raug ntxuav tawm. Yog li ntawd, kuv txiav txim siab siv daim ntawv nplaum uas tau txuas nrog lub vijtsam yas pob tshab. Cov yas feem ntau tseem muaj pob tshab txaus rau ~ 400 nm lub teeb ntawm LEDs.

Thaum kawg cov khoom tuaj yeem raug teeb tsa mus rau hauv 3D luam tsev nyob siv ntau ntau cov kua nplaum kub.

Ua ntej siv tus qauv DS3231 nws yog qhov ntse kom kaw lub roj teeb rov ua haujlwm Circuit. Tsuas yog tom qab tau tsim ntau lub moos nrog tus qauv no kuv tau dawm ntawm txoj xov piav qhia tias VCC txuas nrog lub roj teeb ntawm tes. Qhov ntawd txhais tau tias thaum koj ua lub zog hloov pauv ntawm VCC qhov hluav taws xob tas li siv rau lub roj teeb. Txij li thaum tus qauv tuaj nrog cov roj teeb CR2032 uas tsis tuaj yeem them rov qab tau qhov no tsis yog lub tswv yim zoo. Koj tuaj yeem yooj yim cuam tshuam rau kev rov ua haujlwm Circuit Court los ntawm desoldering diode lossis cov resistor cim hauv daim duab txuas.

Ntxiv mus, cov khoom siv tau txuas nrog siv Dupont cables raws li cov txheej txheem txuas nrog. Cov kauj ruam nce qib tau siv los nce qhov hluav taws xob muab rau I2C lub hnab ev rau 7 V txij li kuv xav ua UV LEDs kom ci li sai tau. Qhov ntsuas hluav taws xob tau thov rau LEDs yog VCC-2 V, piv txwv li 5 V, thaum qhov no siab dua qhov pom zoo rau pem hauv ntej ntawm LEDs (3 V) lawv yuav tsum muaj peev xwm tswj tau nws vim lawv yuav tsis taws teeb tas li.

Kauj ruam 11: Upload Code

Thaum xub thawj, kuv teeb tsa lub sijhawm tam sim no hauv RTC module. Txog qhov no kuv nyuam qhuav tso qhov SetTime piv txwv ntawm DS1307RTC lub tsev qiv ntawv. Tom qab ntawd, cov kab ntawv txuas rau lub moos tuaj yeem rub tawm. Thaum nias lub pob, cov zaub yuav ci rau 5 vib nas this thiab qhia lub sijhawm tam sim no.

Nov yog qee cov duab ntxiv ntawm lub moos tiav. Thaum nruab hnub cov duab thaij duab tuaj yeem siv thaum hmo ntuj nws tuaj yeem sib pauv nrog Glow-in-the-Dark screen.

Zuag qhia tag nrho kuv zoo siab nrog qhov tshwm sim txawm hais tias tus lej ntawm ob qho screesn tseem tuaj yeem ci dua. Lwm qhov muaj peev xwm kuv yuav xav sim yog sib tov ci-hauv-qhov-tsaus cov hmoov nrog epoxy thiab tom qab ntawd siv nws los sau cov ntu ntu siv cov kua nplaum kub. Tsis tas li nws yuav yog qhov zoo los siv PCB kev tshaj lij nrog SMD LEDs hloov ntawm 5 hli LEDs.
