London Daim Ntawv Qhia Hauv Paus Sijhawm: 9 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Xyoo 2014, tawm tom qab ntawm kev xyaum ua haujlwm ntawm 3D kev sab laj luam ntawv hauv London thiab kev sim nrog cov xim lithophanes siv lawv cov tshuab Stratasys, Kuv tsim kuv tus kheej mus tam sim no, xim 3D luam tawm ntawm cov raj kab hauv zos mus rau lawv lub chaw haujlwm. Kuv tau txiav txim siab ua ib yam dab tsi los ntawm nws. Lub sijhawm luv 2 xyoos tom qab xyoo 2016 Kuv muaj kuv tus kheej lub tshuab luam ntawv 3D, thiab teeb tsa ua haujlwm ua nws lub moos.

Raws li menyuam yaus kuv txawm hais tias Tokyo Flash digital watches yog qhov zoo tshaj plaws, thiab txiav txim siab tias yuav yog qhov kev tshoov siab rau kev tsim.

Thiab tam sim no nws tsuas yog me me 4 xyoos so kom txog thaum kuv tau txais puag ncig los sau nws!

Thaum cov lus qhia tseeb yuav nyuaj rau rov ua dua, thiab txo tus nqi hauv kev nyiam ua haujlwm PCB tsim khoom hauv ob peb xyoos dhau los tuaj yeem ua rau kuv txoj kev qhia tseeb rau LED tso rau qhov qub. Kuv vam tias cov tswv yim sib qhia yuav ua rau lwm tus ua lub moos txawv txawv los ntawm cov khoom nyias!

Kauj Ruam 1: Pem Hauv Ntej

Raws li tau hais hauv cov lus qhia, qhov no yog xim 3D luam ntawv, Kuv ntseeg lub tshuab Stratasys uas siv lub txaj txaj thiab hloov pauv tus number case cartridge rau phau ntawv thiab xim.

Cov ntaub ntawv poob rau keeb kwm, tab sis txheej no tuaj yeem yog ib yam dab tsi, duab lossis xim ib leeg lithophane yuav ua haujlwm zoo.

Qhov no tau ua hauv 3DS max hauv 2014, tab sis hnub no muaj cov cuab yeej online los hloov cov duab rau hauv SLT raws qhov ci ci

Kauj Ruam 2: Tsim Tus Txheej Txheem Qhia

Nov yog qhov uas peb txiav txim siab qhov nyuaj ntawm txoj haujlwm thiab txoj hauv kev los nyeem lub sijhawm. Cov duab qhia pom 2 lub tswv yim uas kuv tau ua si nrog.

Cov no tau ua los ntawm kev tshuaj xyuas hauv kev tsim thiab kos kab hla nws hauv inkscape.

Qhov no tsis yog lub moos nyeem tau zoo heev, tab sis kuv nyiam lub tswv yim ntawm cov kab sau txhua hnub kom qhov ntawd dhau los ua lub hom phiaj tsim.

Binary suav yog txoj hauv kev siv tau los txo cov suav suav, thiab nws yuav txhim kho kev nyeem tau yog tias binary yog koj li jam, tab sis qhov ntawd ua rau kuv lub tswv yim 'sau kab', yog li tsis yog qhov kev xaiv rau txoj haujlwm no

Nws yog ib qho ntawm Tokyo Flash Watches kom txo qis LED suav tab sis muaj ib ntu suav hauv 3's lossis 5's thiab tom qab ntawv ntxiv rau txhua lub sijhawm uas ntu ua tiav, Kuv siv cov txheej txheem no rau feeb, kom txo lawv los ntawm 60 txog 20 ntxiv rau 2. Kuv tsis tau txhawj xeeb txog qhov tseeb qhov no rau vib nas this.

Kauj Ruam 3: Tsim Cov Txheej Txheem Qhia

Phau ntawv qhia txheej no rau LED's muaj 2 lub hom phiaj, nws tuav cov LEDs nyob rau hauv qhov chaw, thiab nws tiv thaiv kev sib kis ntawm lawv

Nws tau kos ua ib txheej ntawm Inkscape ncaj qha rau saum cov scan uas kuv tau siv rau kev tsim qauv. 1 hli tuab tau ntxiv rau hauv rab ua ntej xa mus rau kuv lub tshuab luam ntawv.

Qhov no yog ib qho nyuaj tshaj plaws uas kuv yuav tsum tau ua ntawm kuv qhov me me Makibox A6, ib feem tau luam tawm hauv abs yog li ib tuj ntawm acetone slurry tau siv los ua kom nws txuas nrog lub platform tsim nrog tsawg kawg warping. Hmoov zoo qhov no tsis pom ntawm cov khoom kawg

Daim duab zaum kawg qhia tias nws tuav lub teeb txhawm rau txheeb xyuas qhov sib nrug.

Hauv qhov pom tom qab, nchuav nruab nrab ntawm cov teeb ntawm kab tuaj yeem ua tau zoo dua rau qhov pom kev, tsis nyuaj rau nyeem, qhov no tuaj yeem ua tiav los ntawm kev ntxiv cov kab lus rau phau ntawv qhia ntawm ob sab luv ntawm txhua lub teeb

Kauj Ruam 4: Txuas cov LEDs

Cov duab nrig qhia pom qhov kev xeem luam ntawv kuv tau ua rau tshuaj xyuas qhov loj me, Kuv tau tsom mus rau LED kom haum rau hauv cov hlua nrog me ntsis quab yuam, qhov tseeb raug tom qab muab tso rau ntawm txhais tes thaum tso cov txheej txheem qhia.

Vim tias qhov ua siab ntev ntawm kuv lub tshuab luam ntawv 3D, qee qhov tau xoob thiab xav tau dab ntawm superglue kom nyob hauv qhov chaw thaum lwm tus tau nruj dhau, tab sis tau txhawb kom nkag mus rau hauv qhov chaw los ntawm kev nias ntawm LED thaum soldering, qhov no yog qhov ua tau zoo dua qhov loj me kom raug, uas muaj qhov xaum xaum tawm ib zaug xaim hauv.

Txhawm rau txo cov xov hlau suav cov LEDs tau muab muag hauv qhov sib piv ntawm 7 los ntawm 8, txhais tau tias tag nrho 55 LEDs tuaj yeem tswj tau los ntawm tsuas yog 13 tus pin, Kuv tau muaj tes rub daim duab qhia chaw ntawm txhua qhov kev sib txuas uas tau ua tsis tiav.

Cov xaim hluav taws xob tau siv yog li cov ntu tuaj yeem nthuav tawm hauv qhov chaw los ntawm cua sov ntu nrog cov hlau thiab tinning ua ntej ua qhov txuas.

Cov txheej txheem no siv sijhawm ntev heev, Kuv xav pom zoo kom tsim PCB

Kauj Ruam 5: Tsim Cov Khoom Siv Hluav Taws Xob

Kuv qhov phiaj xwm pib yog siv Arduino microcontroller nrog RTC, tab sis xaiv rau ESP8266 ntawm Node MCU D1 pawg thawj coj raws li nws tau tso cai rau txuag hnub nruab hnub thiab muaj peev xwm tswj tau WIFI.

Txhawm rau txo tus lej suav ntxiv, Kuv muaj tus lej LEDs zoo tshaj plaws tuaj yeem siv MAX7219 (uas tuaj yeem ua haujlwm tau txog 64 LEDs).

Qhov IC no feem ntau siv los tsav LED 7 Segment cov lus, tab sis nws muaj cov ntaub ntawv siv zoo ib yam rau kuv, teeb pom kev zoo tus lej ntawm LEDs nrog qhov tsawg kawg flickering, nws txawm tias muaj lub teeb ci.

Kuv txiav txim siab siv protoboard rau txoj hlua, tab sis dav dawb hau tau pab rau kev tso chaw ib feem thiab nkag siab txog cov thaiv

Kuv tau txuas kuv cov ntaub ntawv hauv pawg thawj coj, tab sis qhov no yog kuv thawj zaug siv dav dawb hau (thiab ib qho dhau los ntawm tam sim no) yog li lawv tsuas yog siv rau xwb

Kauj Ruam 6: Txuas Hluav Taws Xob

Qhov no yog cov kauj ruam yooj yim rov ua dua, ua raws li Eagle schematic, siv lub taub hau rau ESP thiab LED matrix tau pab ntau heev hauv kev sib dhos.

Tus Pin 1 ntawm Anode & Cathode LED lub taub hau tau cim nrog lub ntsej muag nyiaj, lawv tuaj yeem sib txawv ntawm qhov zoo li 7 yog lwm 8.

Kauj ruam 7: Programming

Raws li peb cov zaub tsis yog cov cim ib txwm muaj, kuv yuav tsum nrhiav txoj hauv kev los saib seb cov khoom twg tig rau qhov twg nws xa mus rau MAX IC hauv HEX. Hmoov zoo kuv paub tsuas yog txaus kom tau txais teeb meem thiab ua tus 'Hex wizard' los coj kuv txawm tias tus qauv kuv xav tso tawm, txhais tes tso lub npov tag nrho.

Qhov no tuaj nrog kev tshuaj xyuas qhov hex rau kuv teev, feeb thiab vib nas this tuaj yeem ua ke siv me ntsis LOSSIS los tsim qhov kawg hex hais kom xa mus rau max7219, suav nrog cov tsiaj me me kuv ntxiv rau vib nas this yog li kuv tuaj yeem paub tseeb tias pawg thawj coj saib tsis tau; tsis khov.

Yog li, yuav luag thaum kawg. thiab sijhawm rau lwm qhov kev txiav txim siab uas tseem tsis tau muaj hnub nyoog zoo.

Cov cai rau ESP yog hauv LUA, Hnub no kuv xav kom siv cov arduino IDE rau nws cov ntaub ntawv zoo dua thiab cov tsev qiv ntawv muaj zog, thaum lub sijhawm ESP zej zog tseem loj hlob thiab kuv tau xaiv LUA ua lus rau txoj haujlwm no.

Kuv tau txiav txim siab qhov lus nug tsis tu ncua ping google servers los nyeem lub sijhawm. Qhov no tau nyob ib puag ncig xav tau RTC kom txo qis, qhov no ua haujlwm, tab sis koj; yuav tsum zoo dua siv lub sijhawm tseeb API.

Tam sim no yog koj lub sijhawm los qhia tawm koj cov txuj ci tsis txaus ntseeg thiab ua haujlwm hauv tsev.

Ib qho ntawd lossis lob pob amazon tawm ntawm kev rov ua dua tshiab thiab ua lub tsev nyob ib ntus uas tseem siv niaj hnub no.

Cov txiaj ntsig ntawm kev siv txoj hauv kev no yog tias txhua txheej ntawm txoj haujlwm yuav luag zoo ib yam nrog cov tuab ntawm cov duab los qhia, yog li cov qhaub cij tuaj yeem teeb tsa thiab kaw ua ke. Cov hwm hwm zoo ib yam tuaj yeem siv acrylic

Ua tsaug rau kev nyeem ntawv, Raws li ntau ntawm koj paub sau cov phiaj xwm tuaj yeem nyuaj li ua nws. muaj cov seem ntawm cov vis dis aus nrog kuv tham uas thaum kawg yuav pom lub teeb ntawm hnub.

Hauv lub xyoo ntawm kev ua txoj haujlwm no thiab sau nws Kuv xav tias yuav pom ntau tus piv txwv ntawm kev xav tsis zoo ntawm LED qhia siv 3D luam ntawv, tab sis kev txo qis hauv RGB kab ntawv feem ntau tshem tawm qhov xav tau rau lwm txoj hauv kev.

Kuv vam tias qhov no tau muab xov xwm, thiab thov nug cov lus raws li kuv yuav sim qhia ntxaws ntxiv ntawm ntu uas tsis txaus siab.
