2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Txhua tus neeg muaj cov laus lossis tshiab dua ATX cov khoom siv fais fab tso ib puag ncig. Tam sim no koj muaj peb txoj kev xaiv. Koj tuaj yeem pov lawv rau hauv koj cov thoob khib nyiab, khaws qee qhov zoo lossis tsim DIY chav ua haujlwm raug tshem tawm lub hwj chim. Cov khoom yog cov av pheej yig thiab cov khoom siv no tuaj yeem xa ntau amps dua li qee qhov niaj hnub hloov pauv. Cia peb tsim nws.

Kauj ruam 1: Saib Video

Cov vis dis aus muab txhua yam piav qhia uas koj xav tau los tsim txoj haujlwm no. Tab sis kuv yuav qhia koj cov kauj ruam tseem ceeb tshaj plaws, txoj hauv kev no koj tsis tuaj yeem ntsia qhov no.

Kauj Ruam 2: Txiav Koj Qhov

Nov yog cov npe ntawm ntu uas kuv tau siv hauv txoj haujlwm no (txuas txuas nrog):

Ebay:

5x Kev Txhim Kho Cov Ntawv (liab):

1x Kev xa xov (dub):

1x Toggle Hloov:

1x 3mm Ntsuab LED:

1x 3mm Liab LED:

2x 220Ω Resistor:

Shrinking tube:

Amazon.de:

5x Kev Txhim Kho Cov Ntawv (liab): https://amzn.to/1xldoN11x Kev khi tus ncej (dub):

1x Toggle Hloov:

1x 3mm Ntsuab LED:

1x 3mm Liab LED:

2x 220Ω Resistor:

Shrinking tube:

Aliexpress: 5x Kev Txhim Kho Cov Ntawv (liab):

1x Cov ntawv cog lus (dub):

1x Toggle Hloov:

1x 3mm Ntsuab LED:

1x 3mm Liab LED:

2x 220Ω Resistor:

Shrinking tube:

Kauj ruam 3: Tau txais Txoj Cai Tiv Thaiv

Tej zaum koj yuav tau pom tias peb yuav tsum tso lub dummy thauj khoom ntawm qhov khoom kom nws ruaj khov txawm tias thaum peb tsuas yog kos me me ntawm qhov tam sim no.

Kuv pom zoo kom dummy load yuav tsum kos yam tsawg 0.5A.

Nov yog kev suav yog tias koj muaj feem ntau ntawm koj lub zog ntawm 5V/3, 3V kev tsheb nqaj hlau:

R = U/I = 5V/0, 5A = 10Ω

P = U*I = 5V*0, 5A = 2, 5W

Yuav nws ntawm no:

Nov yog kev suav yog tias koj muaj feem ntau ntawm koj lub zog ntawm 12V tsheb nqaj hlau:

R = U/I = 12V/0, 5A = 24Ω

P = U*I = 12V*0, 5A = 6W

Yuav nws ntawm no:

Kauj Ruam 4: Ua kom raug Kev Sib Txuas

Txhua lub xov tooj txhais tau li cas thiab nws txuas mus rau qhov twg? Koj tuaj yeem pom schematic ntawm no uas qhia koj yuav ua li cas txuas cov ntu. Xijpeem ntawm no yog kuv cov ntawv sau ntawm qhov schematic:

Txiv kab ntxwv (3, 3V) - 3, 3V liab khi txoj haujlwm

Liab (5V) - 5V liab txoj hlua khi

------------ 10Ω10W resistor

------------- 220Ω resistor ntawm 3mm ntsuab LED

Dawb (-5V) --5V liab khi txoj haujlwm

Daj (12V) - 12V liab txoj hlua khi

Xiav (-12V) --12V liab khi txoj haujlwm

Xim av (3, 3V Sense) - 3, 3V khi txoj haujlwm

Ntshav (5V Standby) - 220Ω resistor ntawm 3mm liab coj

Ntsuab (Hwj chim ON) - Ib sab ntawm lub toggle hloov

Dub (Hauv av) - GND dub khi txoj haujlwm

--------------------- Cathode ntawm 3mm ntsuab LED

--------------------- Cathode ntawm 3mm liab LED

--------------------- 10Ω 10W resistor

--------------------- Lwm sab ntawm qhov hloov pauv

Grey (Lub Hwj Chim Zoo) tsis txuas nrog

Yog tias koj muaj feem ntau ntawm koj lub zog ntawm 12V tsheb ciav hlau ces koj yuav tsum txuas 24Ω tus tiv thaiv rau 12V hloov 10Ω txog 5V.

Kauj ruam 5: Ua tiav

Txhua yam ua haujlwm! Tam sim no koj tuaj yeem tsim cov phiaj xwm hluav taws xob zoo tshaj plaws nrog kev pab los ntawm lub rooj zaum no lub zog siv hluav taws xob!

Zoo siab los tshuaj xyuas kuv li Youtube channel rau ntau txoj haujlwm txaus:
