Maitiro Ekugadzira Redhiyo Yevanoda Zvemagetsi
Zvinhu zvemagetsi zvinogara zvichipa matambudziko akasiyana kune vanofarira. Imwe purojekiti inowanzoshandiswa semukana wekudzidza ndeyekuvaka redhiyo. Kuvaka redhiyo yako pachako hakungokupi kugutsikana nekugadzira chimwe chinhu kubva pakutanga chete, asiwo kunopa kunzwisisa kwakadzama kwekuti zvikamu zvemagetsi zvinoshanda sei. Chinyorwa chino chichatsanangura nhanho nhanho maitiro ekuvaka redhiyo iri nyore kune vanofarira zvemagetsi.
Pendauluan
Redhiyo mudziyo wemagetsi unoshandiswa kugamuchira mafungu eredhiyo uye kuashandura kuita ruzha. Maredhiyo anoshanda nekubata masaini eRF (Radio Frequency) kubva kumuchina wekutumira uye kuashandura kuita mafungu eruzha anonzwika. Kuvaka redhiyo kunoda zvikamu zvakawanda zvemagetsi zvakaita se resistors, capacitors, inductors, uye transistors, pamwe chete nesosi yemagetsi.
Zvishandiso nezvinhu
Usati watanga, iva nechokwadi chekuti une maturusi nezvinhu zvinodiwa. Heino runyorwa rwezvinhu zvakakosha zvinodiwa pakugadzira redhiyo iri nyore:
1. Antena - inoshandiswa kubata masaini eRF.
2. Macapacitor - kusefa nekuchengetedza masaini emagetsi.
3. Resistor - kudzora magetsi ari mudunhu.
4. Inductor - kuchengetedza simba muchimiro chesimba remagineti.
5. Transistor - kuwedzera masaini emagetsi.
6. Sipika kana Earphone - yekuburitsa ruzha.
7. Simba Rinopihwa (9V Bhatiri) – senzvimbo yemagetsi.
8. PCB (Bhodhi reDunhu Rakadhindwa) - sehwaro hwedunhu.
9. Tambo neSimbi Inosungirira - kubatanidza zvikamu.
Kunzwisisa Magadzirirwo Edunhu
Usati wabatanidza, unofanirwa kunzwisisa dhayagiramu yeredhiyo. Dunhu reredhiyo reAM rine zvikamu zvikuru zvakati wandei: antenna nefirita, tuner, detector, uye audio amplifier. Heino tsananguro pfupi yechikamu chimwe nechimwe:
1. Antena neSefa: Chikamu ichi chinotora masaini eredhiyo kubva mumhepo uye chinosefa masaini anodiwa.
2. Tuner: Chikamu ichi chinosarudza frequency chaiyo yechiratidzo chinogamuchirwa neantenna.
3. Chinoongorora: Chikamu ichi chinoparadzanisa chiratidzo chenzwi kubva kune chinotakura redhiyo.
4. Chinosimudzira Ruzha: Chikamu ichi chinowedzera ruzha kuitira kuti rwunzwike kuburikidza nemaspika kana mahedhifoni.
Matanho Ekugadzira Redhiyo
Danho 1: Kugadzira Antena neFirita
Antena ndiyo chinhu chekutanga chauchada. Unogona kugadzira antenna iri nyore uchishandisa waya refu (inenge mamita 1-2). Uchafanirawo kuwedzera capacitor ne inductor kuti ugadzire resonant circuit iyo ichasefa chiratidzo chakagamuchirwa.
"`Chinyorwa chakajeka
Zvidimbu zvinodiwa:
– Waya yemhangura ye 1m
- 1 10nF Capacitor
– 1 100μH Inductor
``
Danho rechipiri: Kuunganidza Tuner
Tuner inoshandiswa kusarudza frequency chaiyo kubva kuchiratidzo chinogamuchirwa neantenna. Tuner inowanzo kuve ne variable capacitor uye inductor yakabatana zvakafanana.
"`Chinyorwa chakajeka
Zvidimbu zvinodiwa:
– 1 capacitor inoshanduka 10-200pF
– 1 100μH Inductor
``
Danho rechitatu: Muchina wekuongorora
Chinoongorora chinoparadzanisa chiratidzo chenzwi kubva kune chinotakura redhiyo. Pano, unogona kushandisa diode yechinoongorora senge germanium diode.
"`Chinyorwa chakajeka
Zvidimbu zvinodiwa:
– 1 Germanium diode (1N34 kana yakafanana)
- 1 10nF Capacitor
``
Danho rechina: Chinosimudzira Ruzha
Ma-amplifiers eaudio anoshandiswa kuwedzera masaini eaudio. Unogona kushandisa transistor seamplifier iri nyore.
"`Chinyorwa chakajeka
Zvidimbu zvinodiwa:
– 1 NPN transistor (semuenzaniso 2N3904)
– 1 1kΩ resistor
– 1 10kΩ resistor

Kuunganidza Dunhu
1. Tanga neAntena neSefa:
Batanidza mugumo wewaya yeantenna kune inductor ye100μH. Batanidza mugumo weinductor kune capacitor ye10nF, uye batanidza mugumo we free capacitor pasi.
2. Mugadziri:
Batanidza capacitor inoshanduka ye10-200pF kune inductor ye100μH (isina kufanana ne inductor iri paantenna). Batanidza rimwe divi re capacitor inoshanduka pasi.
3. Muchina wekuongorora:
Batanidza germanium diode pakati pe capacitor ne inductor iri pa tuner. Batanidza rimwe divi re diode kune 10nF capacitor, uye batanidza 10nF capacitor pasi.
4. Chinosimudzira Ruzha:
Gadzira circuit yeamplifier uchishandisa transistor yeNPN. Batanidza emitter yetransistor pasi uchishandisa resistor ye1kΩ. Batanidza hwaro hwetransistor kune detector output kuburikidza ne resistor ye10kΩ. Batanidza muunganidzi wetransistor kune speaker output kuburikidza ne capacitor ye100μF. Batanidza rimwe divi respeaker kune positive power supply kubva kubhatiri re9V.
5. Kubatanidza Maseketi Ese:
Batanidza zvikamu zvese zvakaungana netambo dziri paPCB. Iva nechokwadi chekuti kubatana kwega kwega kwakabatana zvakanaka uye kuti hapana mashort circuits asingadiwe pakati pemitsetse.
Kupedzisa uye Kuedzwa
Kana zvikamu zvese zvabatanidzwa, iva nechokwadi chekuti waongorora kaviri kubatana kwega kwega. Kana zvese zvakabatana nemazvo, unogona kubatidza redhiyo nekubatanidza bhatiri re9V.
– Kuedza Kwekutanga: Isa bhatiri re9V wotenderedza capacitor inoshanduka kuti utarise kana paine chiratidzo cheredhiyo. Kana usina kunzwa chero chinhu, tarisazve kubatana uye zvikamu. Chimwe chinhu chingave chakabatana zvisina kunaka kana kuti pangave paine chikanganiso mucircuit.
– Kugadzirisa: Ungangoda kugadzirisa zvimwe zvinhu pa variable capacitor kuti uwane radio frequency yaunoda.
Nekutsungirira uye mwoyo murefu, uchakwanisa kugadzira redhiyo yako wega! Iri ipurojekiti inogutsa zvikuru uye inogona kushanda sehwaro hwemamwe mapurojekiti emagetsi.
Mhedziso
Kuvaka redhiyo ipurojekiti inonakidza uye inodzidzisa zvikuru kune vanofarira zvemagetsi. Nekutevera matanho ari pamusoro apa, unogona kuvaka redhiyo iri nyore uye kuwana kunzwisisa kwakadzama kwekuti zvikamu zvemagetsi zvinoshanda sei. Chirongwa ichi hachingopi chete kunzwisisa kunoshanda kwenheyo dzemagetsi asiwo chinopa kunzwa kwakasiyana kwekugutsikana mukugadzira chishandiso chinoshanda kubva kuzvikamu zvemagetsi. Rombo rakanaka uye unakirwe nechido chako chemagetsi!
