2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Cov Lus Qhia no yog kev taug qab mus rau nixie tube tus qauv tsav tsheb (Tshooj I) uas kuv tshaj tawm ntawm no. Nixie pawg thawj coj tsav tsheb tau tsim los kom tau txais cov lus nkag los ntawm lub microcontroller sab nraud (Arduino, thiab lwm yam) thiab tso tawm cov lej zauv thiab txoj hauv kev rau ib khub nixie tub. Cov nixie hlab txuas rau saum nixie lub rooj tsav tsheb uas txhawb nqa ob IN-12A hom nixie hlab hauv ob lub qhov muag phenolic. Qhov xav tau hluav taws xob tsawg kawg yim khub ntawm IN-12A nixie tubes tuaj yeem muab lub zog hluav taws xob siab. Txoj cai kaum tus txiv neej thiab poj niam header pins ntawm nixie tus tsav tsheb tso cai rau ntau khub ntawm nixie hlab kom koom nrog ntug-rau-ntug. Cov txheej txheem ntom ntom ntim no tso cai rau qhov tsawg kawg ntawm qhov nrug thaum sib txuas lub zog thiab cov ntaub ntawv txuas mus rau txhua lub ntsiab lus.

Kauj Ruam 1: Daim Ntawv Teev Npe

1 - nixie tus tsav tsheb luam tawm Circuit Board 2 - K155ID1 (74141) 16 -pin IC 1 - 74HC595 16 -pin IC 3 - 16 -pin IC socket 2 - ncaj 12 -pin poj niam header (1x12) 2 - sab xis -6 -pin txiv neej lub taub hau (1x6) 2 - sab xis 6 -tus pin poj niam lub taub hau (1x6) 2 - 47k 1 watt resistor 1 - 100 uF electrolytic capacitor 1 - 0.1 uF hlau zaj duab xis capacitor

Kauj ruam 2: Pawg Txheej Txheem

Nixie cov tsav tsheb tuaj yeem sib sau ua ke li ntawm 45 feeb. Rau cov tshiab rau kev sib dhos hluav taws xob, ntawm no yog ob qhov txuas rau kev qhia ua haujlwm zoo heev: Sparkfun, thiab Cov Neeg Tsim Txiaj Ntsig. Nco ntsoov ua tib zoo qhia tus nixie tus tsav tsheb luam tawm lub rooj tsav xwm nrog cov ntaub ntawv tso ua ke sib ntsib. Nov yog sab uas yuav tau txais tag nrho cov khoom siv uas tau muab.

Kauj ruam 3: Sib dhos

Ntxig rau txiv neej thiab poj niam txoj cai 6-tus pin headers raws li qhia thiab pib siv cov laug. Cov taub hau no tuaj yeem tuav ntawm qhov hnyav ntawm pawg thawj coj saib. Thauj tog rau nkoj tus pin nrog cov laug ntawm ob qho kawg ua ntej, thiab paub meej tias txoj haujlwm kawg, ua ntej siv tag nrho cov pins.

Kauj Ruam 4: Ntxig rau 16-pin DIP Sockets

Nco tseg qhov indent ntawm txhua ntawm 16-tus pin DIP qhov. Teem qhov kev nkag mus no nrog cov cim hauv lub rooj tsavxwm, tom qab ntawd ntxig thiab txhuam tag nrho peb qhov DIP qhov nyob hauv qhov chaw. Nws nyuaj heev los kho txoj haujlwm ntawm DIP lub qhov (socket) tom qab nws tau muab muag rau lub rooj tsav xwm luam tawm. Ib lub tswv yim zoo yog ua ntej thauj lub qhov (socket) los ntawm kev siv ob lub kaum kaum tus tawm tsam. Ua li no, lub qhov (socket) yuav tsis hloov ua ntej tus pin txuas tau ruaj ntseg. Qhov kev nkag mus ntawm DIP qhov nyob sib xws rau qhov nkag nkag zoo ib yam ntawm ob K155ID1 (74141) ICs thiab ntawm 74HC595 IC. Peb ICs no yuav tsum tau muab tso rau hauv lub qhov (socket) tom qab tag nrho cov khoom siv tas lawm.

Kauj Ruam 5: Ntxig rau 12-pin Poj Niam Headers

Ob qhov ncaj 12-tus pin poj niam lub taub hau tuaj yeem muab ntxiv tom ntej. Koj tuaj yeem siv qhov hnyav ntawm lub rooj tsavxwm los tuav cov no hauv qhov chaw thaum siv cov laug. Ib yam li ntawd, nws yog lub tswv yim zoo los pib nrog cov pins kawg, thiab txheeb xyuas txoj haujlwm kawg, ua ntej yuav siv cov pins ntxiv.

Kauj Ruam 6: Ntxig rau De-coupling Capacitors

Muaj ob lub de-coupling capacitors ntawm txhua tus neeg tsav tsheb nixie. Nrhiav C1 ntawm lub rooj tsavxwm, thiab ntxig rau cov hlau uas tsis muaj lub ncov qaumteb qabteb zaj duab xis (hauv qab daim duab liab). Muab nws tso rau hauv qhov chaw thiab txiav cov hlau lead. C2 nyob ntawm qhov kawg ntawm lub rooj tsavxwm thiab muaj qhov sib txawv. Qhov tsis zoo ntawm C2 yog mus rau sab nrauv ntawm lub rooj tsavxwm; qhov ua tsis zoo ntawm lub capacitor no tau cim nrog cov qhab dawb. Ntxig C2 raws li qhia, muab nws tso rau hauv qhov chaw thiab txiav cov hlau lead.

Kauj Ruam 7: Ntxig rau Resistors R2 thiab R3

Ob qhov kawg ntawm nixie pawg thawj coj tsav tsheb yog tam sim no txwv cov neeg tawm tsam rau ob lub raj nixie. R2 thiab R3 yuav tsum tau npaj rau qhov siab tsawg kawg ntawm lub rooj tsavxwm; ua li ntawd yuav ua kom lub rooj zaum zoo rau nixie tube board saum toj no. Tig hla ib txoj hauv kev ntawm txhua tus tiv thaiv thiab ntxig lawv ntsug rau hauv txoj haujlwm rau kev siv tshuaj txhuam. Tuav thiab luas cov coj ntawm sab nraub qaum.

Kauj Ruam 8: Ntxig rau Resistors R2 thiab R3 - Xaiv

Nyob ntawm qhov loj me ntawm tus tiv thaiv R2 thiab R3 uas koj muaj, koj yuav pom tias nws nyuaj rau nruab lawv kom lub nixie tube board yuav tso ncaj ncaj saum nixie board board. Koj kuj tseem tuaj yeem xaiv, yog li, nce R2 thiab R3 kab rov tav raws li qhia. Muab hais tias cov tshuaj tiv thaiv no tau ntsuas ntawm ib watt, koj kuj tseem tuaj yeem xaiv los hloov lawv nrog 1/2 watt rated resistors (me dua qhov loj me), nyob ntawm nixie hlab raug tsav. (Qhov no yog qhov xwm txheej txaus rau IN-12A hom nixie tubes.)

Kauj Ruam 9: Ntxig ICs rau hauv Qhov Ncauj

Peb ICs tam sim no tuaj yeem tso rau hauv lawv lub qhov (socket) kom nyab xeeb. Tsis yog ib qho ntawm ICs no yog ntawm CMOS ntau yam, thiab tsis tshwj xeeb tshaj yog cuam tshuam rau hluav taws xob zoo li qub. Nco ntsoov tias ICs los ntawm lub Hoobkas muaj tus pin teeb ntawm lub kaum sab xis dav dua li yuav haum rau hauv IC qhov (socket). Koj tuaj yeem maj mam yob IC ntawm nws sab kom zoo ib yam khoov hauv txhua kab ntawm tus pin kom nws thiaj li tuaj yeem tso rau hauv nws lub qhov (socket). Qhov no yuav tsum tau ua nrog kev saib xyuas, txawm li cas los xij, ib zaug IC pins tau tsom mus rau hauv lub qhov (socket), yuav siv lub zog loj los zaum rau IC.

Kauj Ruam 10: Muab R2 thiab R3

Thaum txuas lub nixie raj board saum toj no nixie tus tsav tsheb, ncaj qha rau sab saum toj ntawm R3, raws li qhia, nkag mus rau hauv lub qhov hauv lub rooj tsavxwm saum toj no. Qhov no tiv thaiv kev sib cuag nrog lub nixie raj pins. Tsis tas li, khoov me ntsis hauv R2 kom tso cai ob lub rooj zaum zaum ncaj.

Kauj Ruam 11: Arduino lossis Freeduino Interface

Pawg thawj coj tsav tsheb nixie tso cai rau microcontroller (Arduino, thiab lwm yam) los hais txog ob lub nixie raj tus lej, thiab ntawm kev hloov pauv rau npe saw, ntau khub ntawm nixie raj lej. Daim ntawv teev npe 74HC595 hloov pauv tau siv ntawm no txhawm rau txuas ntxiv cov kev tswj hwm microcontroller. 74141s yog qhov tshwj xeeb hauv qhov uas lawv tau ua kom tiv taus qhov hluav taws xob siab uas lub nixie tubes ua haujlwm. Koj yuav pom cov lej ntsuas rau Arduino microcontrollers hauv qhov txuas, thiab cov txheej txheem thiab cov txheej txheem txheej txheem txheej txheem rau nixie tsav tsheb tswj hwm ntawm no. cov haujlwm zoo, tseem pom Freeduino qhov chaw qhib qhov chaws.
