Ua ntej peb saib ntawm kev npaj Arduino/Freeduino microcontroller rau kev txuas mus rau nixie raj tsav tus qauv piav qhia hauv Tshooj I thiab Ntu II, koj tuaj yeem tsim lub zog siv hluav taws xob no kom muab qhov hluav taws xob hluav taws xob siab xav tau los ntawm cov hlab nixie. Qhov kev hloov pauv lub zog siv hluav taws xob tau yooj yim tso tawm 50 mA, uas yog ntau dua, thiab muab qhov hloov pauv tau los ntawm 150 txog 220 VDC, thaum tsav los ntawm 9 mus rau 16 VDC qhov chaw.

Kauj ruam 1: Txog Circuit Court

Ib qhov 12 volt ntawm ib lub amp yuav yooj yim tsav lub raj nixie no. Muaj lub zog txaus tsim los ntawm qhov kev hloov pauv hom no kom tsav yam tsawg kawg yim ntawm nixie tube tsav tsheb modules (Kuv tau muaj 12 ntawm nixie tube tsav tus qauv khiav tawm ntawm ib ntawm cov laug cam, uas yog 24 IN-12A nixie hlab!). Ib qho nixie raj fais fab mov muab 170 rau 250 VDC ntawm 10 txog 50 mA. Kev hloov pauv lub zog siv hluav taws xob yog qhov xav tau vim tias nws me me thiab ua haujlwm tau zoo. Koj tuaj yeem haum nws hauv koj lub moos thiab nws yuav tsis sov. Cov txheej txheem rau txoj haujlwm tau coj ncaj qha los ntawm MAX1771 cov ntawv teev tseg, txawm li cas los xij, vim tias qhov hluav taws xob loj dhia los ntawm cov tswv yim mus rau cov zis, kev teeb tsa pawg thawj coj thiab yam tsawg ESR yam khoom yog qhov tseem ceeb.

Cov ntu no Kuv Ieave rau qhov ua kom zoo tom qab kuv tau txais txhua qhov me me saum npoo ntu ntawm lub rooj tsavxwm.

Kauj Ruam 4: Cub Qhov Cub

Nov yog cov ntu me me uas peb yuav siv rau lub rooj sib tham luam tawm nrog cov kua nplaum, thiab tom qab ntawd ci hauv peb lub qhov cub.

Kauj Ruam 5: Muab Tshuaj Txhuam

Tau nrog cov khoom gooey. Rub cov tshuaj txhuam hniav tawm ntawm koj lub tub yees thiab muab sijhawm rau kom sov. Tom qab ntawd nws tsis tawv heev thaum koj sim yuam nws tawm ntawm lub raj. Qhov zoo tshaj plaws yog tias yog koj lub rooj tsavxwm muaj lub npog ntsej muag zoo, koj tsis tas yuav yog qhov tseeb. Thaum cov tshuaj txhuam tsoo lub qhov cub nws yuav ntws mus rau qhov koj xav tau (feem ntau - saib cov kauj ruam 9).

Kauj Ruam 6: Daim Ntawv Thov Muab Tshuaj Txhuam

Teeb tsa thiab tuav cov caffeine vim tias koj xav tau txhais tes khov kho rau txoj haujlwm no. Muab koj tus ntiv tes xoo hla lub plunger thiab maj mam nyem qhov muab tshuaj txhuam rau hauv cov pawm. Tsis txhob txhawj ntau yog tias koj tsis tas li ntawm lub cim. Kev muab tshuaj ntau dhau yuav txhaws qhov zoo, yog li mus yooj yim.

Kauj Ruam 7: Pre-Heat Cub

Thaum koj paub tias cov khoom siv mus qhov twg, nws tau nrawm siv cov nyiaj muab tshuaj txhuam no rau hauv pawg thawj coj saib me. Qhov no yog hais txog qhov tsim nyog muab tshuaj txhuam kom ua tiav ci. Tawm koj cov cuab yeej tuaj tos thiab tso rau ntawm SMDs.

Kauj Ruam 8: Lub Rooj Sib Tham Hauv Cov Paste - thiab Toast

Cov tshuaj txhuam hniav siv ntawm no yog tsis muaj hmoov txhuas, thiab txawm hais tias nws zoo li npub thiab tsaus ntuj tam sim no, tsuas yog tos kom txog thaum nws tawm hauv qhov cub. Tus qauv teeb meem toaster qhov cub Kuv siv Kuv tau txais rau $ 20. Nws tau txais 3/8 dav quartz cua sov saum toj thiab hauv qab lub qhov cub. Kuv tuaj yeem ci rau ntawm cov laug cam no ib zaug. board rau hauv lub qhov cub thiab tuav nws ntawm 200 deg F rau 4 feeb 2. Nqa qhov kub kom txog 325 deg F rau 2 feeb 3. Tuav ntawm 450 deg F rau li 30 vib nas this kom txog thaum lub tshuab ci tawm tuaj, tom qab ntawd tos 30 feeb ntxiv 4. Kais sab ntawm lub qhov cub, thiab txo qhov kub kom 300 degrees F rau 1 feeb 5. Cia kom txias, tab sis tsis nrawm heev.

Kauj Ruam 9: Kev Tshawb Xyuas Tom Qab Toast

Tom qab lub rooj tsavxwm tau txias, tshuaj xyuas nws rau qhov hloov pauv thiab cov laug txuas. Koj tuaj yeem pom qee cov hlaws dai ntawm qhov chaw uas lawv yuav ntsib teeb meem. Maj mam coj lawv tawm thiab tawm ntawm lub rooj tsavxwm. Ua oh. Nws zoo li peb tau txais ob txoj hlua txuas ntawm sab xis ntawm 8-pin IC.

Kauj Ruam 10: Solder Wick Yog Koj Tus Phooj Ywg

Nov yog qhov chaw ua haujlwm deft tiag tiag tshwm sim. Kiv cua qhib qhov kawg ntawm cov hlua khwb khiab khiab khiab khiab khiab kom nws yuav tuaj nqa cov khoom siv yaj. Muab nws tso rau ntawm qhov chaw txuas kab txuas, thiab nias nrog cov hlau kub. Siv cua sov tsis pub ntev tshaj 5 txog 7 vib nas this. Qhov no feem ntau yog txhua yam koj yuav tsum tau ua kom tshem tus choj txuas. Yog tias nws tsis ua haujlwm rau koj thawj zaug, tej zaum sim ua kom lub rooj tsavxwm los ntawm lwm lub kaum sab xis.

Kauj Ruam 11: Cov Khoom Siv Tseem Tshwm Rau Cov Luam Ntawv Circuit Board

Ok, rub mus rau koj lub chaw nres tsheb solder, thiab nrhiav cov khoom sib koom ua ke nyob rau theem 3. Peb yuav luag tiav. Ob txoj hlua txuas txuas ntawm cov kauj ruam hloov pauv tau raug tshem tawm nrog cov laug cam, thiab lub rooj tsavxwm tau ua tiav tam sim no.

Kauj Ruam 12: Txuas HV Hwjchim rau Nixie Tube Tsav Qauv

Yog tias koj tab tom txuas qhov hluav taws xob siab nixie raj fais fab mov rau lub nixie raj tsav tsheb module, ntawm no yog qhov kev sim yooj yim teeb tsa. Xa mus rau cov cim ntawm ib sab ntawm lub dav hlau ntsuab ntawm daim phiaj hluav taws xob luam tawm. Rau lub ntsiab PWR cov tswv yim hluav taws xob muab rau lub nixie raj lub zog siv hluav taws xob uas qis dua 15 volts DC, koj tuaj yeem txuas PWR thiab Vcc cov dav hlau ua ke. Rau lub ntsiab PWR cov tswv yim hluav taws xob muab rau nixie tube lub zog siv hluav taws xob uas siab dua 15 volts DC, koj yuav tsum tau ntxig tus tswj hwm (7812) txhawm rau muab 12 volts DC rau Vcc lub davhlau ya nyob twg. Yog tias siv lub tshuab hluav taws xob 12 volt AC, piv txwv li, PWR lub davhlau ya nyob twg thiab Vcc lub davhlau ya nyob twg yuav tsum txuas nrog lub xaim jumper luv. Rau kev ua haujlwm ib txwm, tseem txuas Shdn lub davhlau ya nyob twg rau GND nrog cov xaim xaim hluav taws xob. Qhov no yuav ua rau lub nixie raj fais fab mov los tsim cov khoom tawm thaum lub zog nkag tau muab.

Kauj Ruam 13: Lub Hwj Chim Tawm Tswv Yim

HV+ thiab HV- cov ntawv lo rau ntawm lub nixie tube lub zog xa khoom sib xws nrog HV thiab gnd ntawm nixie raj tsav tsheb module. HV- txhuas txuas rau tus pin 1 ntawm SV1 (gnd), thiab HV txhuas txuas rau tus pin 4 ntawm SV1. Rau SV1 thiab SV4, tus pin 1, 2, 5, thiab 6 txhua tus txuas nrog gnd. Tsuas yog tus pin 3 thiab 4 ntawm SV1 thiab SV2 nqa qhov hluav taws xob siab xav tau los ntawm cov hlab nixie.

Kauj Ruam 14: Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Thoob Hauv Cov Qauv

Tam sim no koj muaj lub hwj chim muab rau lub nixie raj tsav tsheb modules, koj yuav tsum pom tag nrho cov ntsiab lus hauv ob lub nixie raj tus lej teeb pom kev zoo. Siv kev ceev faj tsis txhob kov lub siab tso zis rau lub nixie raj tsav modules. Muaj peev xwm txaus lub zog ntawm no kom ua rau muaj kev poob siab loj. Thaum nixie raj tsav tus qauv tau txuas nrog ntug-rau-ntug, sab laug-rau-sab xis, ob lub zog hluav taws xob siab thiab cov ntaub ntawv txuas los ntawm cov microcontroller sab nraud tau sib txuas mus rau txhua lub laug cam. tsav tsheb ua haujlwm hloov pauv cov npe saw. Lub nixie raj tsav tus qauv tso cai rau lub microcontroller (Arduino, thiab lwm yam) los hais txog ob tus nixie raj tus lej, thiab ntawm qhov kev hloov pauv no sau npe saw, ntau khub ntawm nixie raj tus lej. Rau ib qho piv txwv ntawm yuav ua li cas nixie tube tus qauv tsav tsheb tuaj yeem txhawb nqa los ntawm tus tswj hwm sab nraud, saib tus qauv Arduino tus lej tus lej tsav tsheb. Ntau tus nixie raj tsav tus qauv tau pom ua haujlwm ua ke hauv nixie tube tsav tsheb module. Nyob ntawm qhov ci ntsa iab koj xav kom koj lub raj nixie ci ntsa iab, koj tuaj yeem hloov kho VR1 los tsim cov zis ntawm 170 thiab 250 volts DC. Ua kom lub zog tso tawm tseem yuav tso cai rau koj tsav ntau lub nixie hlab ib txhij. Lub sijhawm nyob rau ntu IV, qhov twg peb yuav txuas tus Arduino Diecimila, thiab ua qee tus lej ntev heev. Ua tsaug tshwj xeeb ntxiv rau Nick de Smith. Saib qhov no zoo me ntsis ntawm kev ua haujlwm los ntawm Marc Pelletreau. Whew!
