Pinpointer manja: chithunzi ndi kufotokozera

Pinpointerami masiku ano amatchedwa zitsulo zoyesera yaying'ono. Malinga molondola kalasi iwo zosiyana. Tiyeneranso adzanyamula kukumbukira kuti mtundu chipangizo ali tilinazo yake. Waukulu mchitidwe pinpointera angatchedwe ndi koyilo. Iyo imakhala izo makamaka orthogonal mtundu. Komabe, imeneyi, zambiri zimadalira kalasi molondola chida. Kuti kusonkhanitsa losavuta pinpointer manja awo, ayenera kukhala bwino ndi masanjidwe odziwika.

Model pa ziwiri waya capacitor

Kuchita mtundu pinpointer manja, m'pofunika woyamba wa zonse kukonzekera nyumba kwa chipangizo. Kuti tichite zimenezi, akatswiri ambiri amalangiza ntchito tochi yachibadwa. The vuto lalikulu pa siteji iyi ndi kupeza modulator wabwino. Monga ulamuliro, awiri-waya capacitor kukatenga sanali liniya analogi. Mwachindunji omangidwa koyilo kutayidwa pamaso pa chipangizo. Mabatire ayenera kuikidwa kwa modulator lapansi. Chotsani iwo akhoza kukhala a tochi. mphamvu yochepa batire chofunika kukhala 200 mah. Patatha mphindi 25 opareshoni mosalekeza izi zokwanira.

Kugwiritsa atatu waya capacitors

Pangani kovuta ndi atatu waya capacitors pinpointer manja. The modulator mu nkhani iyi ndi yekhayo woyenera liniya mtundu. Mu nthawi yathu kupeza mu masitolo zamagetsi si kophweka. Tiyeneranso adzanyamula kukumbukira kuti koyilo ayenera kuikidwa pansipa mkuzamawu lapansi. Ena zida zina ndi chipangizo zener. Kuonjezera tilinazo chitsanzo, iwo ifeyo. Mabatire imeneyi, mukhoza kugwiritsa ntchito tochi muyezo.

Model kusokoneza mbendera

Kusonkhanitsa mtundu pinpointer manja, m'pofunika woyamba wa zonse kubulusa manungo a tochi lapansi. Osachepera pakhomo pafupipafupi modulator ayenera kulimbana 200 Hz. Zonsezi kudzakuthandizani kukhalabe tcheru chipangizo pa mlingo mkulu. Monga Tester chipangizo Izi ntchito nthawi zambiri. Kuti yambitsa ndi usokoneze mode pomanga m'pofunika kukhazikitsa ulamuliro.

Nthawi zambiri ndi ntchito batani-mtundu. Pankhaniyi, muyenera khutu ku mbali ya thupi, amene anali wokwatibwa ndi tochi. Koyilo Mwaichi bwino kusankha yosavuta. Komabe, athandizira voteji malire chofunika kuti anakhalabe pa 15 V. Zonsezi kusintha molondola kuwerenga.

Kusinthidwa "Mwana-FM2"

Sungani pinpointer "Mwana-FM2" ndi manja ake ndi wosavuta. Anati chipangizo yodziwika kuti ndi otsika ku tilinazo. Komabe, mtengo wa chitsanzo ndi otsika kwambiri, ndi chipangizo anati abwino ntchito kunyumba. The modulator Pankhaniyi mtundu sanali liniya. Iye wokwera mwachindunji pafupi yang'anira lapansi.

Nthawi zambiri izo akutembenukira analogs angapezeke mu msika. Inductor athandizira pakhomo voteji angathe komabe munthu pazipita 10 V. Tiyeneranso kukumbukira kuti chipangizo panopa madutsidwe apamwamba. Izi anali zimatheka ndi khazikitsa ndi zener diode. Komanso, kukweza manja awo pinpointer "Mwana-FM", m'pofunika capacitors solder. Only ndiye kugwirizana kulankhula kwa zener diode. Kumapeto kwa ntchito kokha kukonza mabatire mlanduwo.

Pinpointer otsika tilinazo transistors

Pangani otsika tilinazo pinpointer ndi manja ake pa transistors kungakhale chifukwa chipangizo monga beeper a. Iwo waikidwa mu thupi kumbuyo modulator lapansi. Mkuzamawu kwa chipangizo ichi ndi abwino zimachitika mtundu. Choncho capacitors mwina anasankha zipangizo zosiyanasiyana. Komabe, osachepera athandizira pakhomo voteji, iwo ayenera kukhala pa 5 V.

Iwo ayenera kukumbukira kuti chipangizo zener kawirikawiri anaika. Reserve pafupipafupi olandiridwa pa 200 Hz. Nkofunika kukumbukira kuti ndi lolondola kuwerenga zimadalira inductance wa koyilo lapansi. M'lifupi amafotokozera HIV ndi zambiri zosakwana 3 microns. Mabatire kwa zitsanzo asankhidwa ndi mphamvu osati oposa 600 mah. Mokwanira za izi, chipangizo mosalekeza kwa mphindi 30.

Mkulu tilinazo Model

Mkulu tilinazo pinpointer momwe manja anu? Kuti timvetse funso limeneli, tiyenera kuona kuti koyilo adzafunika mwachilungamo mphamvu khamu. Osachepera pakhomo voteji ayenera kulimbana pa 20 V. Iwo ayenera kukumbukira kuti modulators Pankhaniyi okha oyenera mzere mtundu. Kulondola chimadaliranso mtundu wa condensates.

Imeneyi, akatswiri ambiri amalangiza ntchito zitsanzo lotseguka. Pafupifupi wakhala mphamvu mu chinthu deta ndi kuzungulira 5 PF. Komabe, imeneyi, zambiri zimadalira amapanga capacitors. Ngati ife kulankhula za zener diode, amagwiritsidwanso ntchito ndi kuchuluka kukana. M'pofunika kuwonjezera tilinazo chipangizo. Mabatire kwa chitsanzo ayenera anasankha ndi mphamvu osachepera 900 mah.

Kusinthidwa wa Minimax-PP

Kusonkhanitsa manja awo pinpointer Minimax-PP, muyenera kukatenga beeper PP20 zino. Iwo ayenera kukumbukira kuti makinawa kugwedera anaika mu zipangizo za mtundu uwu. Pankhaniyi, zizindikiro ntchito zosiyanasiyana. Ngati ife kulankhula za koyilo, izo ntchito mu mulandu orthogonal mtundu. Pakhomo athandizira voteji ofiira adzakhala kupirira osachepera 15 W. The kukana mu dera sayenera upambana 4 ohms.

The tilinazo chipangizo makamaka zimadalira capacitor lapansi. A okwana awiri mu chiwembu muyezo anapereka. Mmodzi wa iwo kwenikweni anaika pafupi koyilo lapansi. Pano, wachiwiri wokwera pa kuchoka pa modulator lapansi. The vuto lalikulu mwa zipangizozi tinganene kuti yaing'ono m'lifupi transmittance pa 2 microns. Chifukwa cha zimenezi, amplifiers ntchito zipangizo za mtundu uwu n'zochepa.

Chipangizo ndi yofunika Mtsogoleri

Kodi mtundu pinpointer manja (chiwembu pansipa) ndi wosavuta. Choyamba m'pofunika kuti chipangizo kutola nkhani yabwino. Pankhaniyi, Mtsogoleri yofunika mtundu zambiri danga si zatenga. Ngati akufuna, lingathe kukopedwa pa sitolo iliyonse ndi luso wailesi, ndi ndalama zochepa kwambiri. The amadziwika chifukwa cha mchitidwe izi zikhoza ankaona madutsidwe wabwino. The capacitors Pankhaniyi anakhazikitsa ziwiri elekitirodi mtundu. kukana chizindikiro mu pafupifupi awo zikuuluka kuzungulira 2 ohms.

Iwo ayenera kukumbukira kuti koyilo ayenera kuikidwa choyamba. Iwo adzakhala ndi ntchito blowtorch. Komanso Ufumuyo mwachindunji modulator. Mu gawo kumbuyo akhale batire rechargeable. The mkuzamawu Pankhaniyi ntchito ndi zosayenera. Iwo amayamba ndi chakuti tilinazo chipangizo ali kwambiri yafupika chifukwa kuwonjezera pafupipafupi Kuchepetsa wa chida cha.

Ntchito capacitors multilayer

Izo multilayer capacitors pinpointer manja awo (chiwembu pansipa) yekha pamaso pa coils orthogonal. The modulators Pankhaniyi ali oyenera liniya ndi mitundu sanali liniya. Tiyeneranso adzanyamula kukumbukira kuti zipangizo za mtundu uwu nthawi zambiri anaika njira akututuma. Pankhaniyi, beepers angapezeke zambiri.

Kuwonjezera tilinazo zipangizo zener Mankhwalawa amagwiritsidwa ntchito. Mu chotchuka kwambiri masiku ano ndi kardiodnye Anzawo. Kukhazikitsa iwo adzayenera ntchito ndi blowtorch. Ambiri, tisaiwale kuti zitsanzo ndi capacitors Mipikisano wosanjikiza ndi chilengedwe, ndi abwino ntchito kunyumba. Ndi thandizo lawo, munthu akhoza mwachilungamo mofulumira kupeza malo enieni a Kulumikizana pakhoma.

Model pa bolodi monolithic

Sungani mtundu pinpointer manja ndi wosavuta. Kusiyana zipangizozi osati mkulu kuwerenga molondola, komanso tilinazo wabwino. Kwa ogwira anati chitsanzo agwirizane bwino. Sungani chipangizo ndi zofunika chikukonzekera modulator. Pankhaniyi, akatswiri ambiri kulengeza ntchito analogues liniya.

Komabe, zosintha sanali liniya n'kofalanso. Beeper Pankhaniyi zakonzedwa kuti koyilo lapansi. Chizindikiro athandizira chipangizo pakhomo voteji sayenera upambana 20 V. Chifukwa chaichi zener mokakamiza anapereka. Amazilamulira Pankhaniyi soldered ankafuna. Kumapeto kwa ntchito kokha kukonza mabatire.

Pinpointer ndi ulamuliro kumveka

Kuti pindani chipangizo ndi kumveka yang'anira, m'pofunika kukonzekera pasadakhale ndi blowtorch. Unit oyamba kusankhidwa kwa khalidwe modulator. Akatswiri ambiri kulengeza ntchito analogues liniya imeneyi. Kuwapeza mu sitolo ndi zovuta, koma iwo ayenera kukhala laling'ono. Wapakati madutsidwe zingawathandize wofanana 3 microns. Chifukwa ichi, athandizira pakhomo voteji kuti ankaganiza pa 15V Zener diodes ali oyenera osiyanasiyana ambiri. Fundo pazipita akuyenera kukhalabe pa mlingo wa 5 ohms. Iwo ayenera kukumbukira kuti umalamulira beeper chipangizo osafunika.

Khazikitsa koyilo mu Pankhaniyi m'pofunika asamathe. Mu nkhani iyi, Kulumikizana kutchinjiriza laperekedwa mwapadera. Tiyeneranso kukumbukira kuti mpanda ayenera kwathunthu airtight. Chifukwa chaichi, monga njira ina zotheka kugwiritsa ntchito chisindikizo mphira. Mwachindunji yang'anira ayenera soldered kuti modulator lapansi. Capacitors imeneyi makamaka ntchito mtundu kumunda. Osachepera mphamvu batire ali wofunikila kukhala 800 mah.
