Momwe Mungapangire Wailesi ya Okonda Zamagetsi
Zosangalatsa zamagetsi nthawi zonse zimakhala ndi zovuta zapadera kwa okonda. Pulojekiti imodzi yomwe nthawi zambiri imagwiritsidwa ntchito ngati mwayi wophunzira ndi kupanga wailesi. Kupanga wailesi yanu sikuti kumangokupatsani chisangalalo chopanga china chake kuyambira pachiyambi, komanso kumakupatsani kumvetsetsa kwakuya momwe zida zamagetsi zimagwirira ntchito. Nkhaniyi ifotokoza pang'onopang'ono momwe mungapangire wailesi yosavuta kwa okonda zamagetsi.
Pendauluan
Wailesi ndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kulandira mafunde a wailesi ndikuwasandutsa kukhala mawu. Mawailesi amagwira ntchito potenga zizindikiro za RF (Radio Frequency) kuchokera ku chotumizira ndikuzisintha kukhala mafunde omveka. Kupanga wailesi kumafuna zigawo zingapo zamagetsi monga zotsutsana, ma capacitor, ma inductor, ndi ma transistors, komanso gwero lamagetsi.
Zida ndi zipangizo
Musanayambe, onetsetsani kuti muli ndi zida ndi zipangizo zofunika. Nayi mndandanda wa zinthu zofunika popanga wailesi yosavuta:
1. Antena - imagwiritsidwa ntchito kujambula zizindikiro za RF.
2. Ma capacitor - kusefa ndi kusunga zizindikiro zamagetsi.
3. Chotsutsa - chowongolera mphamvu yamagetsi mu dera.
4. Choyambitsa - kusunga mphamvu mu mawonekedwe a mphamvu yamaginito.
5. Transistor - kukulitsa zizindikiro zamagetsi.
6. Sipika kapena Earphone - kuti mutulutse mawu.
7. Mphamvu Yoperekera Mphamvu (Batri ya 9V) – monga gwero la mphamvu.
8. PCB (Bodi Yosindikizidwa ya Circuit) - monga maziko a dera.
9. Zingwe ndi Chitsulo Chosungunula - cholumikizira zigawo.
Kumvetsetsa Ma Schematics a Dera
Musanayike, muyenera kumvetsetsa chithunzi cha wailesi. Chigawo chosavuta cha wailesi cha AM chimakhala ndi zigawo zingapo zazikulu: antenna ndi fyuluta, chotulutsira mawu, chowunikira, ndi chokulitsa mawu. Nayi kufotokozera mwachidule kwa gawo lililonse:
1. Antena ndi Fyuluta: Gawoli limatenga ma siginecha a wailesi kuchokera mumlengalenga ndikusefa ma siginecha omwe mukufuna.
2. Chosinthira: Gawoli limasankha kuchuluka kwa chizindikiro chomwe chimalandiridwa ndi antenna.
3. Chowunikira: Gawoli limalekanitsa chizindikiro cha mawu ndi chizindikiro chonyamulira wailesi.
4. Chokulitsa Ma Audio: Gawoli limakulitsa chizindikiro cha mawu kuti chimveke kudzera m'ma speaker kapena ma earphone.
Njira Zopangira Wailesi
Gawo 1: Kupanga Antena ndi Fyuluta
Antena ndiye chinthu choyamba chomwe mungafune. Mutha kupanga antena yosavuta pogwiritsa ntchito waya wautali (pafupifupi mamita 1-2). Muyeneranso kuwonjezera capacitor ndi inductor kuti mupange dera lozungulira lomwe lidzasefa chizindikiro cholandiridwa.
"`Mawu osavuta
Zigawo zofunika:
– Waya wa mkuwa wa 1m
- 1 10nF Capacitor
– 1 100μH Inductor
``
Gawo 2: Kusonkhanitsa Chojambulira
Chotulutsira mawu chimagwiritsidwa ntchito kusankha ma frequency enaake kuchokera ku chizindikiro chomwe antenna imalandira. Chotulutsira mawu nthawi zambiri chimakhala ndi capacitor yosinthika ndi inductor yolumikizidwa motsatizana.
"`Mawu osavuta
Zigawo zofunika:
– 1 chosinthira mphamvu (variable capacitor) 10-200pF
– 1 100μH Inductor
``
Gawo 3: Chowunikira
Chowunikira chimalekanitsa chizindikiro cha mawu ndi chizindikiro chonyamulira wailesi. Apa, mungagwiritse ntchito chowunikira monga germanium diode.
"`Mawu osavuta
Zigawo zofunika:
– 1 Germanium diode (1N34 kapena yofanana nayo)
- 1 10nF Capacitor
``
Gawo 4: Chokulitsa Ma Audio
Ma amplifiers a audio amagwiritsidwa ntchito kukulitsa ma audio signals. Mutha kugwiritsa ntchito transistor ngati amplifier yosavuta.
"`Mawu osavuta
Zigawo zofunika:
– Transistor imodzi ya NPN (monga 2N3904)
- 1 1kΩ resistor
- 1 10kΩ resistor
– 1 100μF Capacitor
- 1 Sipika yaying'ono kapena chogwirira cha m'makutu

Kusonkhanitsa Dera
1. Yambani ndi Antena ndi Fyuluta:
Lumikizani kumapeto kwa waya wa antenna ku inductor ya 100μH. Lumikizani kumapeto kwina kwa inductor ku capacitor ya 10nF, ndikulumikiza kumapeto kwa capacitor pansi.
2. Chosinthira:
Lumikizani capacitor yosinthika ya 10-200pF ku inductor ya 100μH (yosiyana ndi inductor yomwe ili pa antenna). Lumikizani mbali ina ya capacitor yosinthika pansi.
3. Chowunikira:
Lumikizani germanium diode pakati pa capacitor ndi inductor pa tuner. Lumikizani mbali ina ya diode ku capacitor ya 10nF, ndikulumikiza capacitor ya 10nF pansi.
4. Chokwezera Ma Audio:
Pangani dera lokulitsa mawu pogwiritsa ntchito transistor ya NPN. Lumikizani chotulutsira mawu cha transistor pansi kudzera mu resistor ya 1kΩ. Lumikizani maziko a transistor ndi chotulutsira mawu kudzera mu resistor ya 10kΩ. Lumikizani chosonkhanitsa cha transistor ndi chotulutsira mawu kudzera mu capacitor ya 100μF. Lumikizani mbali ina ya chotulutsira mawu ku magetsi abwino ochokera ku batri ya 9V.
5. Kulumikiza Ma Circuit Onse:
Lumikizani ziwalo zonse zomwe zasonkhanitsidwa ndi zingwe zomwe zili pa PCB. Onetsetsani kuti kulumikizana kulikonse kwalumikizidwa bwino komanso kuti palibe ma short circuits osafunikira pakati pa mizere.
Kumaliza ndi Kuyesa
Zigawo zonse zikalumikizidwa, onetsetsani kuti mwayang'ananso kawiri kulumikizana kulikonse. Ngati chilichonse chalumikizidwa bwino, mutha kuyambitsa wailesi polumikiza batire ya 9V.
– Kuyesa Koyamba: Ikani batire ya 9V ndikuzungulira chosinthira cha capacitor kuti muwone ngati pali chizindikiro cha wailesi. Ngati simukumva chilichonse, onaninso kulumikizana ndi zigawo zake. Chinachake chingalumikizidwe molakwika kapena pakhoza kukhala vuto mu seti.
– Kukonza: Mungafunike kusintha zina ndi zina pa capacitor yosinthika kuti mupeze ma frequency a wailesi omwe mukufuna.
Mukapirira pang'ono komanso moleza mtima, mudzatha kupanga wailesi yanu! Iyi ndi pulojekiti yokhutiritsa kwambiri ndipo ingakhale maziko a mapulojekiti ena a zamagetsi.
Mapeto
Kupanga wailesi ndi pulojekiti yosangalatsa komanso yophunzitsa kwambiri kwa okonda zamagetsi. Mwa kutsatira njira zomwe zili pamwambapa, mutha kupanga wailesi yosavuta ndikupeza kumvetsetsa kwakuya momwe zigawo zamagetsi zimagwirira ntchito. Pulojekitiyi sikuti imangopereka kumvetsetsa kothandiza kwa mfundo zoyambira zamagetsi komanso imaperekanso chisangalalo chapadera popanga chipangizo chogwira ntchito kuchokera ku zigawo zoyambira. Zabwino zonse ndipo sangalalani ndi zomwe mumakonda pa zamagetsi!
