Tsis ntev los no kuv tau txaus siab rau astronomy thiab lub hnub qub ntsia hauv kuv lub sijhawm dawb thiab pom tias muaj txhua yam kev txaus siab uas tuaj yeem siv tau los ua lub hnub qub zoo dua. Ib qho ntawm thawj yam uas kuv pom kuv xav tau yog lub teeb nyem liab kom pab kuv nyeem kab ntawv hnub qub, nyeem teeb tsa ntawm kuv lub tsom iav, xaiv qhov muag qhov muag, nrhiav yam uas poob hauv cov nyom, taug kev ib puag ncig yam tsis cuam tshuam rau yam, thiab ntau ntxiv!

Vim li cas cov kws saib hnub qub siv lub teeb liab liab? Muaj ntau cov lus piav qhia zoo rau qhov no ntawm lub vev xaib. Cov lus teb luv yog astronomy yooj yim dua ua thaum koj ob lub qhov muag tau hloov mus rau qhov tsaus ntuj li 15 feeb lossis ntau dua. Qhov kev hloov pauv no tuaj yeem thim rov qab tam sim thaum ib tus raug lub teeb - tshwj xeeb yog lub teeb dawb lossis xiav. Yog li, lub teeb liab liab tuaj yeem ua haujlwm tsis txaus ntseeg thaum ua astronomy. Ntau npaum li ntawd, uas yuav luag txhua tus kws saib hnub qub nqa lawv thaum lawv tawm ntawm lub hnub qub-tsom iav, saib lub hnub qub, lossis ua ib qho haujlwm qis qis.

Yog li, kuv yog tus tsim khoom nquag. Thaum twg los xij kuv xav tau qee yam tshiab - cov cuab yeej tshiab lossis khoom ua si piv txwv - Kuv sim ua qee yam uas kuv tau ua haujlwm, lossis tsim qee yam tshiab ua ntej yuav khoom. Qhov no coj kuv mus rau qhov kev xav paub xav tsim lub teeb liab rau kev tshawb fawb astronomy. Qhov kev tshawb nrhiav ntawd coj kuv mus rau txhua qhov chaw saib PWM cov kab hluav taws xob thiab Arduino tswj rau kev ua kom pom LEDs los tswj qhov ci ci. Kuv tau txais kev zoo siab heev uas kuv tau siv sijhawm me ntsis tsim kho lub teeb liab liab liab kho tau siv lub 555 timer Circuit.

Alas, kuv qhov pheej yig tau txais thaum kuv tsim cov khoom pov tseg (saib ntau cov lus qhia ntawm qhov no). Cov khoom pov tseg suav nrog 2032 (lossis zoo sib xws) lithium roj teeb, LED, thiab qee daim kab xev. Qhov ntawd yog nws. Kuv siv lub teeb liab liab LED rau kev tshawb fawb hnub qub ib ntus, tab sis pom nws tsis yooj yim rau kab xev thiab tsis xev. Kuv xav tau qhov hloov pauv, thiab rooj plaub uas kuv tuaj yeem teeb thiab muab tso rau hauv lub hnab. Nrog tuaj lub hnub qub tog hauv PA (The Cherry Springs Star Party) xyoo 2017 thiab kuv pom tias kuv xav tau yam tsawg kawg ntawm 5 tus nqi qis, teeb pom kev zoo liab liab rau kuv tsev neeg siv nyob rau ib hmo nyob ntawm lub hnub qub tog. Cov khoom pov tseg los rau hauv siab, tab sis yuav tsis yooj yim rau kuv tus poj niam thiab menyuam. Yog li, kuv txiav txim siab hloov kho qee lub teeb tshuaj yej pheej yig uas peb tau yuav ntawm Amazon. Cov lus qhia no yuav qhia koj yuav ua li cas kom ua ib lossis ob peb tus nqi qis, ua haujlwm tau, teeb liab LED teeb rau kev tshawb fawb astronomy siv cov khoom los ntawm Amazon thiab cov hlau txuas.

Kauj Ruam 1: Astronomer's Tea Teeb - Daim Ntawv Teev Npe thiab Tus Nqi

Txoj haujlwm no yog tsim los ntawm cov npe yooj yim zoo nkauj raws li qhia hauv qab no.

1. Cov Tshuaj Yej Teeb (Amazon $ 13.99/24 teeb)

2. 50 Ohm Resistors (Amazon $ 7.99/25 50 Ohms)

3. Liab LEDs (Amazon $ 7.95/10 liab)

Kuv siv cov khoom no rau lwm yam, yog li muaj lwm txoj hauv kev pheej yig dua. Kuv yuav 24 lub teeb tshuaj yej vim tias peb siv lawv rau ntau yam nyob ib puag ncig lub tsev. Kuv yuav cov khoom sib xyaw ua ke vim kuv siv lawv rau lwm txoj haujlwm. Kuv yuav cov teeb sib xyaw ntawm LEDs vim kuv xav tau lwm yam xim. Koj tuaj yeem yuav me me ntawm cov tshuaj yej teeb, tsuas yog 50 ohm resistors, thiab tsuas yog LEDs liab.

Siv kuv daim ntawv teev npe saum tus nqi yuav yog $ 13.99+$ 7.99+$ 7.95 = $ 29.93 rau ib rau kaum. $ 3 txhua tus tsis phem heev. Nws pheej yig dua li lub teeb liab liab LED tshwj xeeb, tab sis nws tuaj yeem pheej yig dua. Txij li thaum kuv npaj yuav siv txhua ntu los ntawm cov khoom siv kuv tsuas yog siv 13.99/24+7.99/750+7.95/100 = $ 0.67/teeb! Tsis phem!

Kauj Ruam 2: Astronomer's Tea Teeb - Tsim Txheej Txheem

Kev tsim rau txoj haujlwm no yooj yim heev.

1. Tshem lub teeb tshuaj yej. 2. De-solder dawb LED uas twb muaj lawm. 3. Solder lub 50 Ohm resistor rau lub liab LED (hauv kev qhia kom raug).4. Solder lub 50 Ohm resistor thiab liab LED rau lub teeb tshuaj yej. 5. Xeem nws! 6. Muab lub teeb tshuaj yej rov los. 7. Koj ua tiav!

Kauj Ruam 3: Disassemble Teas Teeb

Tshem tawm roj teeb.

Tshem tawm sab hauv ntawm cov tshuaj yej teeb siv rab rab qhov ntswg raws li qhia.

Kauj Ruam 4: De-solder LED Dawb Uas Muaj

Ua ib qho kev ceeb toom ntawm kev taw qhia ntawm LED uas twb muaj lawm ua ntej tshem nws. LEDs yog polarized, yog li cov hluav taws xob yuav tsuas ntws hauv ib qho kev taw qhia. Liab LED yuav tsum tau taw qhia tib yam li qhov koj tab tom tshem tawm. Yog tias koj saib sab hauv lub teeb koj tuaj yeem pom tias sab zoo thiab tsis zoo sib txawv. Koj yuav siv cov yam ntxwv sab hauv lub teeb kom raug rau lub teeb liab liab thaum koj mus txog qib tom ntej.

De-solder cov LED dawb uas twb muaj lawm thiab tshem tawm cov seem uas seem los ntawm kev hloov pauv.

Kauj Ruam 5: Solder 50 Ohm Resistor to the Red LED (in the Correct Orientation)

Kuv nyiam khoov cov resistor rau hauv cov duab zoo li hauv daim duab thiab muab cov khoom sib txuas ua ke hauv cov khoom siv thib peb. Nco ntsoov siv flux los ua kom muaj kev sib koom zoo. Yog tias koj xav sim tam sim no koj tuaj yeem txuas cov hlau lead LED thiab cov neeg tawm tsam ua rau lub roj teeb kom ntseeg tau tias koj tau siv cov laug kom raug. Txiav tawm cov hlau lead ntau dhau thiab cov xaim hluav taws xob tiv thaiv.

Kauj Ruam 6: Solder 50 Ohm Resistor thiab Liab LED rau Cov Tshuaj Yej Teeb

Pub cov LED hla lub qhov tso rau hauv cov yas thiab khoov nws mus rau hauv "V" cov duab hauv lub roj teeb. Solder tus tiv thaiv rau qhov hloov qhov twg dawb LED siv los txuas.

Kauj Ruam 7: Xeem Nws

Muab lub roj teeb rov qab rau hauv (hauv qhov qhia kom raug). Qhib tus tes hloov qhov. Nws puas ua haujlwm? Yog li koj zoo mus! Yog tias tsis yog, koj yuav tsum tau rov tsim kho nrog cov LED coj rov qab. Qhov no yuav raug nqi koj li LED, tab sis tsis muaj txoj hauv kev rov ua haujlwm tam sim no.

Kauj Ruam 8: Rov Sib Sau Dua Teeb Teeb

Nco ntsoov qhia lub teeb kom raug thiab thawb cov khoom rov qab ua ke. Nruab lub roj teeb thiab lub roj teeb npog yog tias koj tsis tau ua dua. Koj ua tiav! Nrog koj zoo siab. Tam sim no koj tuaj yeem pom txoj hauv kev tsaus ntuj yam tsis muaj kev cuam tshuam rau koj lub teeb pom kev pom tsawg.
