Kuv qhov tseeb thiab tam sim no qhov kawg me me suab spy kab thiab koj tuaj yeem tsim nws ib yam!

Ua haujlwm ntawm 433MHz, yog superstable vim kev siv SAW resonator thiab siv ib leeg 1.5V khawm ntawm tes!

Kauj Ruam 1: Qhov Chaw thiab Cov Cuab Yeej Xav Tau

Ua ntej kom ntseeg tau tias koj muaj cov cuab yeej/khoom siv hauv qab no:

- solder muab tshuaj txhuam

- nplua qhov taub tooj liab

- nyias kab xaim

- zoo tweezers

- chaw ua haujlwm huv

- ib daim hlau rau tus kav hlau txais xov

Tag nrho lwm qhov hauv BOM koj tuaj yeem pom ntawm no:

Kauj ruam 2: Schematic

Piav qhia qhov txuas nrog PDF schematic (saib hauv qab no):

Mus rau sab laug yog lub microphone, lub suab hais lus yog lub peev xwm ua ke rau theem yooj yim heev thiab tom qab ntawd mus rau lub varactor diode uas hloov kho HF oscillator.

Tus oscillator mus rau sab xis yog qhov yooj yim SAW raws oscillator uas tau "cuam tshuam" los ntawm peb cov suab qis zaus.

Nco ntsoov tias nyob rau hauv kev txiav txim rau lub Circuit Court kom me me li sai tau qhov suav suav suav yuav tsum tau khaws cia kom tsawg li sai tau ib yam nkaus, yog li koj pom ntawm no yog qhov tsawg kawg nkaus li qhov xav tau rau lub hom phiaj.

Cov khoom yuav luag txhua pob khoom 0201 rau cov khoom siv tsis sib xws, lawv yooj yim dua rau sib sau ua ke ntau dua li cov uas kuv tau qhia thawj zaug uas siv 01005 pob.

Lub zog tso tawm tuaj yeem nce ntxiv yog tias R1 qis dua, Kuv sim nws mus rau 100 Ohm lossis li ntawd ib pliag dhau los. Tam sim no yuav nce ntxiv raws li, los ntawm 1mA nrog 620 Ohm mus rau ob peb mA nrog tus nqi R1 qis dua.

Lub zog tseem tuaj yeem nce ntxiv los ntawm kev nce lub zog hluav taws xob kom peb hais 3V. Lub microphone zoo rau 1.45V nkaus xwb txawm li cas los xij koj yuav xav tau nrhiav txoj hauv kev los tiv thaiv nws. Zoo dua lo rau 1.5V:-)

Yog tias kev hloov kho tau ua tiav, zoo li cov tuab tuab tuab lossis tuab tuab cov tooj liab lossis txawm tias SAW zaus tus nqi inductor yuav tsum tau rov kho dua. Qhov no tuaj yeem nyuaj tab sis mus txog 433MHz yeej ua tau.

Kauj Ruam 3: Qhov Chaw Yuav Tau Txais Qhov Twg

Ua ntej koj xav tau PCB. Rub tawm cov ntawv gerber.zip lossis.brd cov ntaub ntawv los ntawm daim nplaub tshev google.

Tom qab ntawd mus rau Oshpark.com thiab xa cov ntaub ntawv gerber.zip lossis.brd, xaiv 0.8mm 2oz, them thiab tos kom txog thaum nws xa tuaj.

Rub tawm BOM los ntawm google drive nplaub tshev thiab mus rau digikey.com. Nrhiav txhua ntu raws li tau piav qhia hauv Youtube video.

Them, tos kom txog thaum xa khoom thiab koj zoo mus.

Kauj ruam 4: Sib dhos

Rub tawm EAGLE Light (dawb) version kom pom lub rooj teeb tsa lossis xa mus rau pawg thawj coj saib duab ntawm no.

- Muab qee cov tshuaj txhuam tso rau ntawm txhua lub ncoo nrog kev pab ntawm rab koob lossis zoo sib xws.

- Muab tag nrho cov khoom siv raws li cov ntaub ntawv.brd txheej txheem.

- Tshav kub txog 250 degrees Celsius thiab tshem tawm cov cua sov kom sai li sai tau thaum cov tshuaj txhuam tau yaj.

- Siv lub kav hlau txais xov xaim

Kauj ruam 5: Txais

Yog tias koj tsis muaj tus txais txais lub dongle pheej yig los ntawm no:

www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/

Koj tuaj yeem nrhiav software dawb rau PC ntawm no:

www.rtl-sdr.com/big-list-rtl-sdr-supported-software/

LOS YOG rub tawm daim ntawv thov sib xws los ntawm Android khw, Kuv siv RF ntsuas ntsuas, rau ob peb daus las.

play.google.com/store/apps/details?id=com.mantz_it.rfanalyzer&hl=en

Koj lub xov tooj yuav tsum muaj kev txhawb nqa OTG vim tias dongle tau siv lub xov tooj.

Kauj Ruam 6: Qhov Kawg

Tam sim no zoo siab spying!
