Dzidziso yekugadzira redhiyo iri nyore kutevera
Kuvaka redhiyo iri nyore hakungopi ruzivo rwekutanga rwemagetsi chete asiwo kunopa kunzwa kwekugutsikana kana uchigona kuteerera nhepfenyuro dzeredhiyo kubva pamudziyo wakagadzirwa kumba. Chinyorwa chino chichapa gwara riri nyore kutevera, nhanho nenhanho rekuvaka redhiyo iri nyore. Dzidziso iyi yakakodzera vese vanotanga neavo vane ruzivo rwekutanga rwemagetsi.
Nhanganyaya kuZvikamu Zvikuru
Usati watanga kugadzira redhiyo, zvakakosha kuti unzwisise zvinhu zvinokosha zvatichashandisa. Heano zvimwe zvinhu zvakakosha pakugadzira redhiyo iri nyore:
1. Resistor: Chinhu chinoshanda kudzivirira magetsi mudunhu. Chinowanzoonekwa muOhms (Ω).
2. Capacitor: Chinhu chinochengeta nekuburitsa simba remagetsi munguva pfupi. Kugona kwaro kunoratidzwa muFarads (F).
3. Inductor: Chinhu chinochengeta simba muchimiro chesimba remagineti kana magetsi emagetsi achipfuura nepakati paro.
4. Transistor: Chinhu chinoshandiswa seamplifier, switch, kana oscillator muma electronic circuits.
5. Diode: Chinhu chinobvumira magetsi kufamba nenzira imwe chete.
6. Antena: Inoshandiswa kugamuchira masaini eredhiyo kubva mumhepo.
7. Waya Inobatanidza: Waya inobatanidza zvikamu zviri muredhiyo.
Matanho Ekugadzira Redhiyo
Heano matanho akadzama ekugadzira redhiyo iri nyore:
1. Gadzirira Zvishandiso Nezvinhu
Usati watanga kugadzira, iva nechokwadi chekuti wagadzirira maturusi nezvinhu zvinotevera:
– Breadboard: Kuronga zvikamu kwenguva pfupi.
– Matambo eJumper: Kubatanidza zvinhu zviri pabhodhi rechingwa.
- 1 kΩ uye 10 kΩ resistors
– 10 µF uye 100 pF capacitors
– 0.1 mH inductor
- Transistor yeNPN (semuenzaniso BC548)
– Germanium diode (semuenzaniso 1N34A)
– Antena (waya refu)
- Simba re9V (bhatiri)
- Maspika madiki kana mahedhifoni
- Simbi inonamirwa nesimbi inonamirwa (kana zvichidikanwa)
2. Kuunganidza Dunhu reMugamuchiri weSignali
Dunhu redhiyo repakutanga rine zvikamu zvakati wandei, zvinoti chinogamuchira masaini, amplifier, uye chinogadzirisa masaini.
Chinogamuchira Chiratidzo:
1. Batanidza antenna kune rimwe divi re inductor.
2. Batanidza rimwe divi reinductor kune capacitor ye100 pF, wobva wabatanidza capacitor pasi.
3. Kuunganidza Dunhu reRectifier
Dunhu rekugadzirisa richashandura chiratidzo cheredhiyo (RF) kuita chiratidzo chinonzwika.
1. Batanidza 1N34A germanium diode pakati pemugumo weinductor yakabatana necapacitor nepasi.
2. Isa capacitor ye10 µF pamwe chete ne diode (anode to ground wobva waisa cathode kune capacitor ye100 pF).
4. Kuunganidza Amplifier Circuit
Dunhu re amplifier rine ma transistors nezvimwe zvinhu zvinotsigira.
1. Batanidza gumbo remuunganidzi weNPN transistor kune rimwe divi re10 kΩ resistor.
2. Batanidza rimwe divi re10 kΩ resistor kune simba rinobva (+9V).
3. Batanidza gumbo re emitter re transistor pasi.
4. Batanidza capacitor ye10 µF pakati pegumbo rekutanga retransistor kune anode yediode.
5. Batanidza sipika diki kana kuti earphone pakati pegumbo remuunganidzi wetransistor nepasi.
5. Zvishandiso Zvinobatanidza
Batanidza sosi yemagetsi ye9V kudunhu:
1. Batanidza terminal yakanaka yebhatiri kumagumo e10 kΩ resistor isina kubatana netransistor.
2. Batanidza negative terminal yebhatiri pasi pesekitori.
6. Kuedza uye Kurongeka
Kana dunhu ragadzirwa, inguva yekuedza redhiyo yako yakagadzirwa kumba.
1. Batidza circuit nekubatanidza bhatiri re9V. Tarisa kana paine zvikamu zvinopisa kana zvinopfungaira. Kana zvakadaro, dzima nekukurumidza woongororazve zvakabatana.
2. Kana pasina matambudziko, edza kuisa antenna munzvimbo yakashama kuti uwane chiratidzo chakasimba.
3. Gadzirisa nzvimbo yeantenna ne variable capacitor (kana iripo) kuti uwane frequency yeredhiyo yakajeka.
4. Teerera mhinduro dzenhepfenyuro kuburikidza nemaspika kana mahedhifoni.
Mazano Ekuwedzera
1. Kunyora Zvikamu: Iva nechokwadi chekuisa mazita pachikamu chimwe nechimwe kuti usavhiringike. Izvi zvichaita kuti zvive nyore kuverenga uye kutevedzera hurongwa hwedunhu.
2. Kubatanidza: Kana uchida kubatanidza zvachose, shandisa simbi yekusanganisa nePCB. Iva nechokwadi chekusanganisa nekungwarira kudzivirira mashort circuits.
3. Antena: Hunhu hweantenna hunokanganisa zvikuru simba kana kusasimba kwechiratidzo chinogamuchirwa. Zvakanakisisa kushandisa waya refu kuti antenna igamuchire zviratidzo zvakawanda.
4. Kudzika pasi: Kudzika pasi kwakanaka kunobatsira kuderedza ruzha uye kuvandudza kunaka kwemasaini. Ita shuwa kuti circuit yacho yakadzika pasi zvakanaka.
Penutup
Kuvaka redhiyo iri nyore ipurojekiti inonakidza uye inodzidzisa zvakawanda. Tinovimba kuti, kuburikidza nematanho ari pamusoro apa, muchakwanisa kugadzira redhiyo inogona kushandiswa kuteerera nhepfenyuro dzemuno. Uyezve, chiitiko ichi chichawedzerawo kunzwisisa kwako kwezvishandiso zvemagetsi uye mashandiro anoita zvikamu mudunhu. Rombo rakanaka, uye rombo rakanaka!
