Kuv ib txwm xav tau lub nixie moos, tsuas muaj qee yam hais txog cov lej ci ntsa iab uas ua rau kuv nyiam. Yog li thaum kuv pom qee qhov tsis kim heev IN12s ntawm ebay Kuv yuav lawv, xav tsis thoob rau lawv thaum kuv tau txais lawv tab sis tsis ntev pom tias txhawm rau ua lub moos tawm ntawm lawv Kuv xav tau qee yam ntxiv. Raws li kuv tsis tuaj yeem nrhiav tau ib lub rooj tsavxwm uas yuav ua tau raws kuv qhov kev qhia tshwj xeeb thiab xav tau kuv muab cov raj tso rau hauv tub rau khoom thiab txhua yam tab sis tsis nco qab txog lawv.
Nkag mus rau JLC PCB nrog tus nqi tsis txaus ntseeg, thaum kawg kuv txiav txim siab los ua kuv tus kheej.
Khoom siv
6x IN12 nixie raj (lwm tus tuaj yeem ua haujlwm tab sis xav tau kev hloov pauv ntawm PCB)
6x SN74141 lossis K155ID1 BDC-rau-decimal decoder
6 x 1.5 kOhm resistor
4x 180 kOhm resistor
4x MPSA42 high voltage transistor
4x 5mm neon teeb (koj tseem tuaj yeem siv cov txiv kab ntxwv LEDs tab sis qhov ntawd yog hom tiv thaiv tus ntsuj plig ntawm no)
4x 74HC595 hloov npe
2x 470nF ceramic capacitor
1x LM7805 5V tus tswj hwm
1x Step-up HV mov
1x DC lub tog raj kheej
1 x Wemos D1 Mini
Kauj Ruam 1: Tsim PCB
Txij li thaum kuv yog tus kiv cua loj ntawm qhov qhib software kuv siv KiCad EDA los tsim PCB. Kuv tshawb nrhiav ntau yam nixie moos tsim ntawm google thiab txiav txim siab siv Lavxias K155ID1 cov tsav tsheb ua ke nrog 74HC595 hloov npe. Lub hlwb ntawm kev ua haujlwm yog Wi-nkaus muaj peev xwm Wemos D1 mini. Raws li kuv pom tus nqi pheej yig HV nce khoom ntawm ebay Kuv txiav txim siab tsis ua nws ntawm lub rooj tsavxwm kuv tus kheej. Tsis tas li kuv tau muaj feem ntau ntawm cov khoom siv tau ua ke thiab tsim cov kauj ruam hloov pauv yuav txhais tau tias muab qee yam ntxiv. Tej zaum lwm zaus.
Kuv paub tias muaj ntau qhov ua tau txhim kho ob qho tib si hauv cov txheej txheem thiab hauv txheej txheej PCB tab sis qhov no yog kuv thawj zaug ua haujlwm nrog KiCad thiab kuv tau tsom mus ntxiv rau qhov khoom kawg.
Tom qab ua tiav cov txheej txheem thiab sim nws ntawm lub khob cij kuv pib tso tawm PCB. Nov yog kev kos duab rau nws tus kheej thiab lub ncauj lus dav heev yog li kuv tsis mus rau hauv cov ntsiab lus ntau dhau ntawm no. Muaj qee qhov yeeb yaj kiab zoo thiab tob hauv online.
Tag nrho KiCad txoj haujlwm muaj nyob ntawm kuv GitHub.
Kauj Ruam 2: Tau Txais PCB Tsim
Tom qab ob thiab triple tshuaj xyuas koj tus qauv nws yog lub sijhawm los tsim nws. Kuv siv los ua nws hauv tsev nrog hloov pauv tus lej cua sov thiab Fe3Cl tab sis cov txheej txheem ntawd tsis meej, xav tau kev npaj ntau thiab muaj, hauv kuv qhov kev paub dhau los, tsis tuaj yeem kwv yees tau thiab tsis sib xws. Yog li raws li tau hais tseg kuv xaiv rau lub tsev tswj hwm kev ua haujlwm. JLC PCB (tsis txhawb nqa) muab tus nqi zoo thiab yog tias koj txaus siab tos lub sijhawm xa khoom ntev (lossis them 10 zaug ntau dua rau kev xa khoom dua li cov laug cam) koj tuaj yeem tau txais cov khoom lag luam uas tsis tawg koj lub txhab nyiaj. Lub rooj tsavxwm muab cov lus qhia ib qib zuj zus hais txog yuav ua li cas xa thiab xa cov ntaub ntawv gerber thiab ua ntej ua, koj tuaj yeem rov tshuaj xyuas koj tus qauv hauv online saib gerber. Tam sim no txhua yam koj yuav tsum ua yog tos kom PCBs raug tsim thiab tshem tawm. Nov yog kev tshuaj xyuas zoo ntawm cov txheej txheem tsim khoom. Yog tias koj tab tom ua ib yam nkaus, koj tuaj yeem xav txog yuav ua li cas nrog 4 sab laug-dhau PCBs raws li qhov tsawg kawg uas koj tuaj yeem xaj yog 5.
Kauj ruam 3: Soldering
Thaum cov PCBs raug xa mus nws yog lub sijhawm ua qee qhov txuas, pib los ntawm qhov tsawg tshaj plaws (lossis qis dua profile) cov khoom ua raws los ntawm qhov loj dua.
Yog tias ua ib yam dab tsi loj dua li ob peb yam kuv ib txwm siv daim nqi ntawm cov ntaub ntawv (BOM), KiCad txawm muaj lub plugin zoo los xa tawm BOM sib tham.
Kauj Ruam 4: Programming ESP
Kuv tau ua cov phiaj xwm hauv VS Code thiab sim ua kom lub firmware hloov pauv tau yooj yim. Tam sim no nws ua haujlwm tab sis muaj ntau chav rau kev txhim kho thiab ntau yam ntxiv.
Cov lej tag nrho muaj nyob ntawm github:
Kauj Ruam 5: Ua Kev Ruaj Ntseg
Kuv pib tsim tsuas yog lub npov yooj yim kom luam tawm 3D raws li lub thawv ntawv tab sis kuv vam tias yuav ua kom cov ntoo zoo dua qub nyob rau qee lub sijhawm yav tom ntej.
Zoo, feem ntau cov kev daws teeb meem ib ntus dhau mus tas li …
Kauj ruam 6: Debugging
Yog li Lub rooj tsavxwm tau npaj tiav, khoos phis tawj tau rub tawm thiab nws yog lub sijhawm los ntsaws lub microcontroller rau hauv thiab muab tso rau ntawm phab ntsa!
Tsuas yog ob lub raj tsis pom kev. Tom qab qee qhov kev tshawb nrhiav thiab tshuaj xyuas zoo dua ntawm pawg thawj coj saib kuv pom tias qee cov ntaub qhwv ntawm cov ntawv hloov pauv tau nyuam qhuav ntab txawm tias lawv tau txuas nrog lub dav hlau hauv av. Nws hloov tawm tias kuv tau nrawm thiab xa cov ntaub ntawv yam tsis tau ua ib qho DRC zaum kawg (Tsim Kev Cai Txheeb Xyuas) tom qab qhov hloov thib ob zaum kawg (Cu sau) yog li qee qhov chaw tau ua tiav tab sis tsis txuas nrog ib yam dab tsi. Kuv kuj tsis nco qab kho HV cov khoom noj thaum txav cov qhov sib dhos …
Zoo, raws li cov ntawd tsuas yog qee qhov kev kho me me kuv tau rub qee cov hlua hlau thiab txuas nrog cov khoom ntab.
Nws ib txwm yog lub tswv yim zoo los ceeb toom ntawm HW kab thiab kho nws hauv PCB tsim, yog tias tsuas yog siv rau yav tom ntej siv.
