Nyob zoo sawv daws. Raws li Christmas los txog, Kuv tau txiav txim siab los tsim kom zoo nkauj Christmas tsob ntoo dai kom zoo nkauj nrog qee qhov LEDs, qee qhov tiv thaiv, thiab 555 timer IC. Tag nrho cov khoom siv xav tau yog THT cov khoom, cov no yooj yim dua rau solder dua SMD cov khoom. Tsis tas li, tsis muaj cov phiaj xwm koom nrog yog li qhov no yog npaj rau cov neeg uas txaus siab pib kawm kom tsis txhob muaj teeb meem nrog ntu me me lossis cov khoom nyuaj ntawm cov lej. Ntxiv rau qhov tshwm sim yog qee yam uas koj tuaj yeem dai ntawm koj tsob ntoo Christmas thiab qhia rau txhua tus neeg koj ua nws!

Nws kuj tseem ua khoom plig Christmas zoo rau cov neeg uas nyiam cov khoom siv hluav taws xob. Hauv cov lus qhia no, Kuv yuav qhia koj yuav ua li cas kom ua kom zoo nkauj zoo nkauj nrog txhua cov kauj ruam xav tau thiab kuv tseem yuav tawm qhov txuas rau kuv lub khw Tindie yog tias koj xav yuav nws ua khoom plig.

Cia peb pib!

Kauj Ruam 1: Qhov Chaw thiab Cov Cuab Yeej

Rau txoj haujlwm no, peb tsuas yog xav tau ib pawg yooj yim, yooj yim mus nrhiav cov khoom:

1x 555 Timer IC (eBay:

17x 1K Resistors (eBay:

1x 100uF Capacitor (eBay:

1x 10K Resistor (eBay:

2x 2025 Npib Cell Holder (eBay:

8x 5mm Liab LED (eBay:

8x 5mm Ntsuab LED (eBay:

Kuv kuj tseem tshuav cov ntawv ua tau zoo nrog txhua qhov khoom siv thiab txuas (BOM).

Thaum nws los txog rau lub rooj tsavxwm, peb muaj ob txoj kev xaiv: vim nws yog txheej txheej ob txheej, qhov yooj yim tshaj plaws yog siv lub chaw tsim khoom PCB los ua lub rooj tsavxwm rau koj. Lawv yog cov pheej yig heev thiab muaj ntau qhov zoo muab thiab txo nqi ntawm thawj qhov kev txiav txim tawm. Qee qhov chaw tsim khoom uas kuv siv yog PCBWay, JLCPCB, thiab SeedStudio.

Lwm qhov kev xaiv yuav yuav cov khoom siv los ntawm kuv lub khw Tindie. Nov yog txoj hauv kev yooj yim kom tau txais qhov no vim tias txhua yam los ua ke. Kuv muag tag nrho cov khoom thiab pawg thawj coj saib. Kuv kuj tseem muaj qhov kev xaiv los ua kom lawv yaj thiab xa daim ntawv tiav.

Electronics Corner Tindie khw txuas:

Txawm li cas los xij, Kuv yuav tso Eagle file rau koj kom xaiv cov tshuaj uas koj nyiam.

Cov cuab yeej xav tau:

-Soldering hlau

-Rosin core solder

Kauj ruam 2: Soldering

Thaum peb muaj tag nrho cov khoom siv, nws yog lub sijhawm los muab tshuaj txhuam.

Ua ntej tshaj plaws, peb tab tom yuav solder 555 Timer. Khoov ob txhais ceg me ntsis, muab tso rau hauv qhov chaw thiab muab tshuaj txhuam rau nws

Qhov thib ob, peb tab tom yuav solder 10K resistor. Tus tiv thaiv no muaj npe R1 hauv pawg thawj coj, yog li cia peb muab nws tso rau hauv qhov chaw.

Tom qab qhov no, peb tab tom yuav solder 1K resistors (17 ntawm lawv!). Cov no mus ntawm R2 txog R18. Pib soldering lawv nrog kev ua siab ntev me ntsis vim tias muaj ntau ntawm lawv!

Ib qho uas peb tau muab pauv rau 1K cov neeg tawm tsam yog lub sijhawm los txhawm rau LEDs! Ua raws li daim duab ntawm pawg thawj coj ua tiav, peb tab tom yuav muab cov xim liab thiab ntsuab ntsuab los hloov. Pib nrog liab liab (L1) thiab txuas ntxiv nrog ntsuab (L2). Ua qhov no kom txog thaum koj khiav tawm ntawm lawv!

LEDs muaj ob txhais ceg, ib qho zoo thiab qhov tsis zoo. Cov coj ntev yog qhov zoo thiab luv luv yog qhov tsis zoo. Hauv PCB, tag nrho cov ceg tsis zoo mus rau sab laug thiab txhua ceg zoo mus rau sab xis.

Tom qab siv tag nrho cov LEDs, yog lub sijhawm rau lub capacitor. Thaum nws los txog rau polarity, capacitors muaj ob txhais ceg ib yam, qhov ntev yog qhov zoo thiab luv luv yog qhov tsis zoo. Solder lub capacitor tom qab kos npe hauv PCB.

Peb yuav luag tiav! Tam sim no, peb yuav tsum tig ib ncig ntawm lub rooj tsavxwm thiab txiav tag nrho cov ceg tivthaiv.

Thaum kawg, peb tab tom yuav cov neeg tuav cov npib ntawm tes, los ua qhov no, tsuas yog ua raws PCB daim duab thiab koj tau ua tiav!

Kauj Ruam 3: Ua Kom Nws Muaj Zog

Tam sim no peb tau ua tiav cov laug peb tsuas yog xav tau ntxiv ob lub CR2032 npib roj teeb ntawm tes kom pom nws!

Kuv vam tias koj nyiam ua qhov kev kho kom zoo nkauj Christmas no. Tam sim no koj tuaj yeem dai nws ntawm koj tsob ntoo Christmas thiab txaus siab rau lub teeb pom kev! Nws tseem yog ib qho khoom zoo nkauj txawm tias nws tawm!

Zoo siab heev Christmas!
