Nov yog phiaj xwm los ua lub moos-thiab hauv kuv qhov xwm txheej, cov ntshav qab zib tso tawm los ntawm lub vintage 1966 HP 5532A zaus ntsuas. Hauv kuv rooj plaub, lub txee tsis ua haujlwm, thiab kuv yuav tsum tau kho qee yam. Cov duab pib no yog qee qhov kev kho. Cov lus qhia no yuav xav tias koj li ua haujlwm, thiab tseem tias koj muaj lub peev xwm thiab muaj lub siab xav teeb tsa thiab teeb tsa Raspberry Pi thiab ua qee qhov coding. Lub peev xwm los tiv thaiv kom nyab xeeb kuj yog qhov yuav tsum tau ua. Vim tias qhov hluav taws xob siab yuav tsum tau tua cov nixies, yuav tsum tau ceev faj heev, thiab lub cuab yeej yuav tsum tsis txhob ua haujlwm thaum txuas nrog lub zog.

Khoom siv

Zaus txee

Soldering hlau/laug

Raspberry PI xoom W.

120VAC 5V USB them nyiaj (yuav lossis tsis xav tau nyob ntawm tus qauv qauv)

Optocoupled solid state relays rau tuav lub nixie voltages (tej zaum lossis yuav tsis xav tau nyob ntawm lub txee)

Python moos chaws

Cov hlau me me

Kauj Ruam 1: Xam Tawm Yuav Ua Li Cas Thiaj Li Ua Rau Lub Counter nce ntxiv

Cov kauj ruam no yuav txawv nyob ntawm lub txee koj muaj. Tej zaum koj tseem tuaj yeem siv lub ntsuas qub qub lossis qee yam khoom siv "digital" qub rau lub moos. Lawv qhov tseem ceeb yog txhawm rau txheeb xyuas seb cov zaub ua haujlwm li cas. Hauv kuv qhov xwm txheej, kuv muaj peev xwm rub tawm phau ntawv qhia txuj ci los ntawm Artek phau ntawv qhia. Kev tshuaj xyuas cov txheej txheem yog dhau qhov uas tau qhia tseg no, tab sis xav tau kev paub txog txuj ci hluav taws xob/khoom siv hluav taws xob. Hauv qhov no, Kuv tau siv lub xaim txuas rau cov hlau lead nkag thiab txuas rau lwm qhov kawg rau GPIO ntawm raspberry pi. Kuv siv Python code txhawm rau hloov GPIO siab thiab qis thiab sim ua kom pom qhov ua haujlwm zoo tshaj plaws. Kuv tau siv lub tshuab rub tawm (10K, kuv xav) los ntawm tus pin GPIO rau hauv av kom tiv thaiv 'ntab'. Kuv kuj txiav qhov txuas los ntawm tus thib kaum xyoo txee mus rau 4, thiab txuas rau lwm tus GPIO tus pin kom kuv tuaj yeem nce tus lej thib 1 3 tus lej sib txawv.

Kuv txiav qhib lub qub 120VAC USB them nyiaj thiab txuas nws mus rau qhov hloov pauv AC cov tswv yim ntawm lub txee, thiab siv lub micro USB qaum rau lub charger tso tawm. Tsis tas li, hauv qhov no, Kuv xav tswj lub teeb zauv los qhia cov ntshav qabzib hloov pauv. Lawv siv 150VDC kom tua hluav taws, yog li kuv yuav tsum tau siv optocoupled solid state relays soldered to the Pi. Lawv tau txuas ncaj qha (nrog txwv cov neeg tawm tsam) rau lub headerless GPIO pawm, uas kuv tau siv los teeb liab qhov xa tawm.

Kauj ruam 3: Teeb Pi

Teem Pi
Teem Pi

Koj yuav tsum teeb tsa koj li Raspberry Pi txuas rau koj li WiFi, thiab thauj Python moos tsab ntawv. Tom qab ntawd koj yuav tsum teeb tsa nws kom pib ntawm khau raj, los ntawm kev tsim cov ntaub ntawv.service. Hauv kuv qhov xwm txheej, kuv muaj kuv tus tub cov ntshav qab zib tso tawm kom pom, nqa cov ntaub ntawv los ntawm lub vev xaib hauv cheeb tsam los tso saib tus nqi thiab kev hloov pauv. Koj tuaj yeem hloov kho nws kom rub cov ntaub ntawv ntsuas kub hauv cheeb tsam (lossis kis las ncaws pob, lossis txhua yam koj xav tau) thiab tso tawm ib yam. Koj yuav tau hloov kho tsab ntawv kom pom lub moos yog tias qhov koj xav tau. Koj tuaj yeem pom hauv tsab ntawv yuav ua li cas nws nce ntxiv ntawm 59 txog 100 thaum xav tau, thiab tig mus rau tus lej tom ntej mus rau sab laug yog tias tsim nyog. Koj kuj tseem yuav tsum tau sim nrog lub sijhawm ntawm cov cim qhia kom suav suav raug; Kuv pom tias cov cuab yeej no tsuas suav tau raug yog tias thawj 5 txoj hauv kev los yog li ntawd muaj qhov me me (.01 thib ob nyob rau hi/qis mem tes) ncua. Tom qab ntawd, lub tshuab tuaj yeem suav tau Pi cycles kom nrawm raws li nws tuaj yeem tsim lawv. Hauv suav thawj 3 tus lej, siv lub oscilloscope, Kuv pom tias kev caij tsheb kauj vab nkag los ntawm -35V lub tsheb npav mus rau hauv av, nrog rau 10K rub -up resistor rau hauv av (rub tawm vim tias nws tau rub los ntawm -35V) yuav tsim kom raug waveform kom nce 10^4 tus lej los ntawm ib qho ntawm txhua lub voj voog. 2 ntawm lub xeev tau tshaj tawm tau siv rau lub hom phiaj ntawd.
