2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Nov yog qhov hloov kho tshiab ntawm kuv Geiger txee los ntawm Cov Lus Qhia no. Nws yog qhov nrov heev thiab kuv tau txais cov lus pom zoo los ntawm cov neeg txaus siab tsim nws, yog li ntawm no yog ntu txuas ntxiv:

Qauv Zauv: GC-20 Geiger txee, dosimeter thiab chaw saib xyuas hluav taws xob tag nrho-hauv-ib! Tam sim no 50% tsawg dua thicc, thiab nrog ntau cov software tshiab nta! Kuv txawm sau Phau Ntawv Qhia Neeg Siv no los ua kom nws zoo li cov khoom lag luam tiag. Nov yog cov npe ntawm cov yam ntxwv tseem ceeb lub cuab yeej tshiab no muaj:

• Touchscreen tswj, nkag siab GUI
• Qhia cov suav ib feeb twg, koob tshuaj tam sim no, thiab cov tshuaj sib sau ua ke ntawm lub vijtsam tsev
• Rhiab thiab ntseeg tau SBM-20 Geiger-Muller raj
• Lub sij hawm sib xyaw ua ke sib txawv rau qhov nruab nrab koob tshuaj
• Sijhawm suav hom rau ntsuas koob tshuaj tsawg
• Xaiv ntawm Sieverts thiab Rems raws li chav nyob rau tus nqi tshuaj pom
• Tus neeg siv kho qhov ceeb toom pib
• Kev kho kom haum kom txheeb xyuas CPM rau qhov koob tshuaj rau ntau yam isotopes

• Lub mloog pob ntseg nyem thiab qhov taw qhia LED toggled rau thiab tawm ntawm lub tsev tshuaj ntsuam

• Offline cov ntaub ntawv txiav
• Tshaj tawm ntau cov ntaub ntawv nkag mus rau huab pabcuam (ThingSpeak) los teeb duab, tshuaj xyuas thiab/lossis khaws cia rau hauv computer
• Saib xyuas Chaw Nres Nkoj hom: ntaus ntawv txuas nrog WiFi thiab nquag tshaj tawm cov cua ib puag ncig mus rau ThingSpeak channel
• 2000 mAh rechargeable LiPo roj teeb nrog 16 teev sijhawm ua haujlwm, micro USB them chaw nres nkoj
• Tsis muaj qhov xav tau los ntawm tus neeg siv kawg, teeb tsa WiFi ua los ntawm GUI.

Thov xa mus rau tus neeg siv phau ntawv siv qhov txuas saum toj no txhawm rau tshawb xyuas cov software nta thiab UI kev taw qhia.

Kauj Ruam 1: Tsim Cov Ntaub Ntawv thiab Lwm Cov Txuas

Txhua cov ntaub ntawv tsim, suav nrog cov cai, Gerbers, STLs, SolidWorks Assembly, Circuit Schematic, Bill of Materials, User Manual and Build Guide can be found at my GitHub page for the project.

Thov nco ntsoov tias qhov no yog kev koom tes ncaj ncees thiab siv sijhawm ntev thiab xav tau qee qhov kev paub txog kev ua haujlwm hauv Arduino, thiab kev txawj ntse hauv SMD kev sib txuas.

Muaj nplooj ntawv xov xwm rau nws hauv kuv lub vev xaib cov vev xaib ntawm no, thiab koj tseem tuaj yeem pom qhov txuas ncaj qha rau cov lus qhia tsim kuv muab tso ua ke ntawm no.

Kauj Ruam 2: Cov Khoom thiab Cov Khoom Xav Tau

Circuit Schematic muaj cov ntawv lo rau txhua qhov khoom siv hluav taws xob uas siv tsis tau siv hauv txoj haujlwm no. Kuv yuav cov khoom siv no los ntawm LCSC, yog li nkag mus rau cov lej hauv LCSC tshawb nrhiav bar yuav qhia cov khoom siv yam xav tau. Cov ntaub ntawv qhia kev tsim mus rau hauv kev nthuav dav ntxiv, tab sis kuv yuav sau cov ntaub ntawv ntawm no.

Hloov tshiab: Kuv tau ntxiv daim ntawv Excel ntawm LCSC daim ntawv xaj xaj rau GitHub nplooj ntawv.

Feem ntau ntawm cov khoom siv hluav taws xob siv yog SMD, thiab qhov no tau xaiv los cawm chaw. Txhua yam tivthaiv passive (resistors, capacitors) muaj 1206 hneev taw, thiab muaj qee qhov SOT-23 transistors, SMAF loj diodes, thiab SOT-89 LDO, thiab SOIC-8 555 timer. Muaj kev cai hneev taw ua rau tus inductor, hloov thiab lub suab nrov. Raws li tau hais los saum no, cov lej khoom rau txhua qhov ntawm cov khoom siv no tau sau rau ntawm daim duab qhia chaw, thiab qhov ua tau zoo dua PDF version ntawm cov phiaj xwm muaj nyob ntawm GitHub nplooj ntawv.

Cov hauv qab no yog cov npe ntawm txhua qhov khoom siv siv los ua lub rooj sib txoos tag nrho, TSIS suav nrog cov khoom siv hluav taws xob sib cais kom xaj los ntawm LCSC lossis cov khoom lag luam zoo sib xws.

• PCB: Txiav txim los ntawm ib lub chaw tsim khoom siv Gerber cov ntaub ntawv pom hauv kuv GitHub
• WEMOS D1 Mini lossis clone (Amazon)
• 2.8 "SPI Touchscreen (Amazon)
• SBM-20 Geiger raj nrog xaus tshem tawm (ntau tus neeg muag khoom online)

• M3 x 8 hli hex tshuab ntsia hlau (Amazon)
• M3 tooj dag threaded insert (Amazon)
• Cov kab xev tooj liab (Amazon)

Ntxiv rau cov ntu saum toj no, lwm yam khoom siv sib txawv, khoom siv thiab khoom siv yog:

• Soldering hlau
• Cov cua kub cua sov chaw nres tsheb (yeem)
• Toaster qhov cub rau SMD reflow (yeem, ua qhov no lossis qhov chaw cua kub)
• Cov hlau xaim
• Muab tshuaj txhuam
• Stencil (yeem)
• 3D tshuab luam ntawv
• PLA ntsiab lus
• Silicone-insulated stranded wire 22 gauge
• Hex yuam sij

Kauj Ruam 3: Cov Rooj Sib Tham

1. Muab tag nrho cov khoom SMD rau PCB ua ntej, siv koj txoj kev nyiam

2. Solder lub roj teeb charger board rau cov pawm SMD-style

3. Solder txiv neej coj mus rau D1 Mini board thiab mus rau hauv qab pawm ntawm LCD board

4. Solder D1 Mini board rau PCB

5. Txiav tawm tag nrho cov protruding ua los ntawm D1 Mini ntawm lwm sab

6. Tshem daim npav SD daim npav los ntawm lub vijtsam LCD. Qhov no yuav cuam tshuam nrog lwm cov khoom ntawm PCB. Ib lub taub ntim dej ua haujlwm rau qhov no

7. Cov khoom siv hla dhau qhov (JST txuas, LED)

8. Muab cov laug cam LCD tso rau PCB NTAWV KAWG. Koj yuav tsis muaj peev xwm de-solder D1 Mini tom qab qhov no

9. Txiav tawm hauv qab-sab protruding txiv neej ua los ntawm LCD board nyob rau lwm sab ntawm PCB

10. Txiav ob daim ntawm cov hlua uas nyob ib ncig ntawm 8 cm (3 hauv) ntev txhua tus thiab hle qhov xaus

11. Kuaj ib qho ntawm cov xov hlau mus rau anode (pas nrig) ntawm SBM-20 raj

12. Siv daim kab xev tooj liab los txuas lwm cov xaim rau lub cev ntawm lub raj SBM-20

13. Tin thiab solder lwm qhov kawg ntawm cov xov hlau mus rau qhov hla qhov los ntawm cov PCB. Xyuas kom tseeb tias qhov tseeb yog qhov tseeb.

14. Tshaj tawm cov cai rau D1 mini nrog koj nyiam IDE; Kuv siv VS Code nrog PlatformIO. Yog tias koj rub kuv nplooj ntawv GitHub, nws yuav tsum ua haujlwm yam tsis xav tau kev hloov pauv

15. Txuas lub roj teeb rau JST txuas thiab txuas lub zog kom pom tias nws ua haujlwm!

16. 3D luam tawm rooj plaub thiab npog

17. Txuas cov tooj dag xov txuas rau hauv rau qhov rau qhov nyob hauv rooj plaub nrog cov hlau txuas

18. Txhim kho PCB sib dhos rau hauv rooj plaub thiab ruaj ntseg nrog 3 8mm ntsia hlau. Ob sab saum toj thiab ib qho nyob hauv qab

19. Muab Geiger raj tso rau ntawm qhov khoob ntawm PCB (mus rau cov hniav nyiaj hniav kub) thiab ruaj ntseg nrog daim kab xev npog.

20. Ntxig lub roj teeb rau saum, zaum saum SMD cov khoom. Qhia cov xov hlau mus rau qhov sib txawv hauv qab ntawm rooj plaub. Ruaj ntseg nrog daim kab xev nplaum.

21. Txhim kho lub hau npog siv peb 22 mm ntsia hlau ntsia hlau. Ua tiav!

Qhov hluav taws xob mus rau Geiger raj tuaj yeem hloov kho siv qhov sib txawv resistor (R5), tab sis kuv tau pom tias tawm hauv lub zog hluav taws xob hauv qhov chaw nruab nrab lub hauv paus ua rau ntau dua 400 V, uas yog zoo meej rau peb Geiger raj. Koj tuaj yeem ntsuas qhov ntsuas hluav taws xob siab siv ib qho kev sojntsuam siab, lossis los ntawm kev tsim hluav taws xob faib hluav taws xob nrog tsawg kawg 100 MOhms ntawm tag nrho cov kev cuam tshuam.

Kauj Ruam 4: Xaus

Hauv kuv qhov kev sim, txhua qhov ua haujlwm tau zoo kawg nkaus hauv peb chav uas kuv tau ua, yog li kuv xav tias qhov no yuav rov zoo nkauj dua. Thov tshaj tawm koj qhov kev tsim yog tias koj ua tiav!

Tsis tas li, qhov no yog qhov haujlwm qhib tau yog li kuv xav pom kev hloov pauv thiab txhim kho los ntawm lwm tus! Kuv paub tseeb tias muaj ntau txoj hauv kev los txhim kho nws. Kuv yog cov tub ntxhais kawm kho tshuab thiab kuv nyob deb ntawm tus kws tshaj lij hauv tshuab hluav taws xob thiab coding; qhov no tsuas yog pib ua txoj haujlwm nyiam ua haujlwm, yog li kuv vam tias yuav muaj cov lus qhia ntxiv thiab cov hauv kev los ua kom nws zoo dua!

Hloov tshiab: Kuv muag ob peb yam ntawm Tindie. Yog tias koj xav yuav ib qho es tsis yog tsim koj tus kheej, koj tuaj yeem nrhiav nws ntawm kuv lub khw Tindie muag ntawm no!
