Hais txog: Suab paj nruag: kuv txoj haujlwm rau ntau tshaj 40 xyoo… Khoom siv hluav taws xob: kuv nyiam ua haujlwm ib txwm muaj. Xav paub ntau ntxiv txog simpletronic »

Qhov hluav taws xob LED flasher Circuit no yuav ua haujlwm tau 10 xyoo ntawm ib leeg 1.5v AA alkaline cell.

Kuv kuj tau suav nrog PC-board. Koj tuaj yeem rub nws hauv PDF hom ntawv ntawm no: PCB rub tawm. Koj tseem yuav pom daim ntawv qhia kev tso ua ke. Xws li lub neej nyob ntev ntawm tes tau ua tiav los ntawm kev txwv qhov nruab nrab ntws tam sim no mus rau tus nqi pib ntawm 50uA (0.05mA).

Kauj Ruam 1: PC-board thiab Cov Ntawv Qhia Tso Npe

DOWNLOAD LINK rau PC-board thiab phau ntawv qhia kev tso ua ke.

Kuv tau ua qhov qauv no uas siv Heatless (txias) toner hloov txoj hauv kev

Kauj Ruam 2: Daim Duab Circuit & Daim Ntawv Teev Npe

IC1: CD4001 (cmos quad NOR rooj vag)

Q1: 2N4401 (NPN transistor)

C1: 100nF (0.1uF) ceramic capacitor

C2: 1nF (0.001uF) ceramic capacitor

C3: 10uF x 12v tantalum capacitor

R1: 4M7 resistor

R2: 2M2 resistor

R3: 4k7 resistor

LED: ultra-high efficiency LED (muaj tam sim no tsawg heev)

T: 1/2 "toroidal ferrite core & 2 meters (6 ft) ntawm 24AWG (0.5 mm) txha hniav laus

BAT: 1.5 alkaline AA cell. (lub roj teeb tuav tau)

Kauj Ruam 3: Cov Lus Qhia Ua Haujlwm Hauv Circuit

Kauj Ruam 4: Ua Tus Transformer

Koj tuaj yeem khaws cov tub ntxhais ferrite los ntawm lub qub PC motherboard lossis cov khoom siv hluav taws xob. Polarity ntawm windings yog ib qho tseem ceeb; yog tias LED tsis teeb thaum luv lub taub hau pins hloov ib qho ntawm cov cua.

Kauj Ruam 5: Ntsuas Qhov Dej Tam Sim No

Cov dej ntws tam sim no yuav tsum nyob ib puag ncig 50uA (0.05mA) thaum lub xov tooj tshiab. Koj tuaj yeem hloov kho tus nqi tam sim no ntawm R2.
