" tub ceev xwm " Teeb Flasher: 3 Kauj Ruam

Nws ua haujlwm li cas: kev hloov pauv transistors (PNP) tsis tuaj yeem txiav txim siab ntawm ib leeg thiab ua li ntawd, nws tsub nqi thiab tso lub kaus mom thiab hloov lub teeb rau thiab tawm. Cov neeg txais khoom yog rau qhov txwv tam sim no. (keeb kwm hu ua "two-transistor dual-led flasher.") Qhov no yog Circuit Court uas siv hauv RC tsheb, xov tooj cua tswj hwm yam (yog tias nws haum), ETC ……., nws yog qhov teeb meem tub ceev xwm flasher. rau qee qhov laj thawj kuv yuav tsum rov ua qhov Circuit no zoo li 3 zaug lossis qee yam, tab sis nws ua haujlwm tau zoo !!!!!!!!! Qhov Circuit no yuav ua haujlwm ntawm 3v lossis 6 v roj teeb XWB! 4.5 lossis 9.0 volts tsis tuaj yeem siv vim tias 9 volts hloov cov coj "flippige", thiab 4.5 volts nrawm nws ntawm qhov nrawm heev. *NCO TSEG*- qhov no tsis yog kuv li Circuit Court, kuv tau txais los ntawm Radioshack cov khoom siv hluav taws xob kawm paub lab, kuv tsis tau txais credit rau qhov Circuit no.-*NCO TSEG*(tab sis nws lom zem los tsim !!!!!)

Kauj Ruam 1: Daim Ntawv Teev Npe ……

2) 9015 Hloov PNP Transistors ($ 0.75) 2) 470 OHM Resistors ($ 1) 2) 100 KOHMS Resistors ($ 1) 2) 10 uF Capacitors ($ 1.19) 2) Leds (ntawm ib qho xim twg) ($ 1.59) Lub voj voog no yuav tsis ua haujlwm yog tias ib qho ntawm PNP transistors rov qab* NCO TSEG* txhawm rau hloov qhov nrawm ntawm qhov ntsais, hloov pauv tus nqi hluav taws xob thiab 2 qhov ntsuas qhov tseem ceeb, tsis yog tus coj resistors tab sis!

Kauj ruam 2: Schematic-assembaly

Ntawm no yog cov schematic rau lub flasher. Kuv tau ua qhov no ntawm kev kos duab 2009, thov txim rau qhov tsis zoo.

Kauj Ruam 3: Tawm

qhov tig tawm yog qhov zoo rau kuv tab sis yog tias koj muaj teeb meem, email rau kuv ntawm [email protected] lossis tawm lus. !!!!)
