Thawj qhov ntawm lub moos yuav tso saib lub sijhawm ib zaug raws li tau piav qhia hauv daim duab kawg. Kuv tau hloov kho nws kom nws muaj peev xwm mus rau hauv ib txwm nyob ntawm hom los ntawm kev ua kom lub sensor npog ntev dua.

Kauj Ruam 3: Pawg Tsim

Kuv yuav tsis nkag mus ntau dhau yuav ua li cas thiaj ua tau PCB vim tias twb muaj ntau cov ntaub ntawv ntawm qhov ntawd. Qee qhov muaj txiaj ntsig Nixie Tube hneev taw muaj nyob ntawm no.

Thaum kuv tsim kuv tus PCB Kuv tau teeb tsa ob lub rooj me me los txo qhov hneev taw nws yuav muaj thaum khuam rau kuv lub dab teg. Kuv pom tias nws muaj txiaj ntsig los luam tawm thiab txiav tawm ib daim ntawv theej ntawm PCB kom paub tseeb tias txhua qhov kuv hneev taw hneev taw thiab cov khoom sib txuas tau sib dhos. Qhov chaw tso cai sim tawm ntawm cov ntaub so ntswg tawg rau i2C thiab lwm cov ntaub ntawv kab los sojntsuam lossis ua haujlwm ib yam nkaus thaum lub sijhawm ntsuas.

Dav dawb hau muaj qhov tshwj xeeb uas tso cai rau koj muab tus qauv 3D rau ib feem, tom qab ntawd xa tus qauv 3D ntawm koj lub rooj tsav xwm mus rau lwm qhov haujlwm. Nws yog kab laum thaum kuv tau siv nws tab sis tseem muaj txiaj ntsig zoo kom paub tseeb tias tsis muaj ib feem cuam tshuam nrog ib leeg.

Txhawm rau txuag chaw kuv tsis suav nrog lub roj teeb them hauv lub moos. Hloov chaw kuv muaj qee tus poj niam DuPont txuas ntawm ib sab ntawm lub moos. Cov duab kawg ntawm cov teeb no qhia txog cov thaiv kuv tau siv. Sab laug yog sab hauv saib, sab xis yog sab nraud. Txhawm rau them lub moos koj txuas cov xov hluav taws xob sab nraud mus rau lub charger sab nraud. Cov kab xiav nyob ze ntawm lub roj teeb tsis zoo nruab nrab yog lub qhov yuam kev txhawm rau tiv thaiv kev ntsaws lub charger rov qab. Txhawm rau tig lub saib koj siv lub jumper cable me me (ntsuab) txhawm rau txuas lub roj teeb + rau VCC ntawm qhov Circuit tiag. Qhov no muab kev yoo mov tsis ruaj ntseg thaum muaj teeb meem. Vim tias qhov teeb tsa koj tsis tuaj yeem ua yuam kev luv lossis txuas rau hauv Circuit Court rov qab.

Kauj Ruam 4: PCB Los Ua Ke

Kuv xaj kuv cov laug cam los ntawm OSHPark vim tias lawv tau nrawm heev, pheej yig thiab muaj xim zoo nkauj: D

Tsis tas li koj tau txais 3 ntawm txhua lub rooj tsavxwm, yog li koj tuaj yeem ua 2 lub sijhawm saib thiab muaj pawg thawj coj thib peb rau kev sim.

Ua QFN cov pob nrog cua kub ua ntej, tom qab ntawv txhuam txhua yam ntxiv pib nrog cov khoom me me. Tsis txhob xaim koj lub raj Nixie lossis HVPS. Yog tias koj muaj lub lauj kaub tais diav thiab lub toaster qhov cub ces koj ua tau zoo heev. Siv lub ntsuas cua ohm los tshuaj xyuas luv ntawm koj li PCB. Yog tias koj ntsuas qhov nruab nrab-siab tiv thaiv luv luv koj yuav muaj cov dej ntws ntau dhau ntawm lub rooj tsavxwm. HV5523 muaj tus pin zoo heev thiab koj tsis tuaj yeem pom yog tias lawv tau txuas rau hauv qab IC. Muab sijhawm rau koj pawg tswj hwm kom txias yog tias koj rov ua haujlwm nws ntev.

Thaum cov khoom siv hluav taws xob qis tau sib sau ua ke, ua haujlwm ib qho program uas yuav hloov pauv txhua tus lej ntawm kev hloov npe. Siv lub logic analyzer lossis multimeter kom paub tseeb tias cov pins raug rub qis thaum xav tau. Kuj xyuas kom koj RTC thiab lwm yam khoom siv tau teb raws li qhov xav tau.

Solder HVPS, tom qab ntawd nixie tubes. Rau Nixie Tubes solder 1 ceg ntawm ib lub sijhawm thiab tsis txhob tso cua sov ntev ntev. Yog tias nws muaj peev xwm tuav tau ob txhais ceg nruab nrab ntawm PCB thiab iav nrog pliers los ua lub rhaub dej kub. Muab sijhawm rau cov raj kom txias tawm ntawm qhov sib txhuam ntawm txhua ceg.

Yog tias koj muaj teeb meem nrog ib feem tsis ua haujlwm thiab koj tsis paub tias nws yog qhov sib koom ua ke, koj tuaj yeem sim "tuag kab" soldering. Tshem tawm cov nti los ntawm lub rooj tsavxwm thiab siv cov xaim zoo txhawm rau txhawm rau txhua lub ncoo ncaj qha. Nco ntsoov tias koj siv xaim nrog txheej txheej txha hniav laus thiaj li tsis muaj cov xov hlau luv ua ke.
