Ua Koj Tus Kheej Zoo VU Meter!
Ua Koj Tus Kheej Zoo VU Meter!

Hnub no peb tab tom saib lub VU meter, nws yog lub hauv paus thiab nws tau tsim.

Txog qhov kawg ntawm qhov kev qhia no, koj yuav tau ua koj tus kheej VU Meter!

Kauj ruam 1: Saib Video

Kuv tau piav qhia txhua yam kom ntxaws hauv daim vis dis aus no los ntawm qhov pib mus rau kev tsim. Muaj txawm tias lub teeb pom kev thaum kawg uas zoo nkaus li txaus ntshai!

Kauj Ruam 2: Txiav Koj Qhov

Koj yuav xav tau cov no rau kev tsim:

2 LM324 ICs.

7 N channel Mosfets. (Kuv siv 55NF06)

2 Cov laug cam ntawm qhov loj ib yam.

LEDs (tus lej nyob ntawm koj cov lus xaiv, kuv siv 60 LEDs.)

DC Jack.

Suab Jack.

IC qhov (tsis yog yuav tsum tau tab sis zoo dua yog tias siv).

1 47uF capacitor.

9 10K resistors.

1 51K resistor.

3 4.7K resistors.

2 100 ohm resistors.

61K resistors.

16.8K resistor.

1 2.2K resistor.

2 3.3K resistors.

1 Buck Converter / 500 ohm resistor (tsis pom zoo).

Kauj ruam 3: Tsim Circuit Court

Ua kom tiav daim paib LED ua ntej thiab sim nws. Tom ntej no ua cov khoom siv hluav taws xob ua kom txhua yam khov kho. Txhim kho 2 PCBs ua ke nrog cov txiv ntseej thiab ntsia hlau. Nco ntsoov tias tsis muaj cov laug txuas nrog cov laug ntawm lwm sab.

Kauj ruam 4: Txaus siab rau

Qhov ntawd yog nws! Koj tau ua koj tus kheej VU Meter!

Vam tias koj nyiam qhov DIY no. Sau npe yuav ua rau peb cov channel raws li #INNOVATIONMATTERS:
