Maitiro Ekuvaka Redhiyo Uine Kugona Kugamuchira Mafrequency Akasiyana-siyana Maredhiyo ndeimwe yemidziyo yemagetsi inonakidza kudzidza nezvayo, ichibatanidza pfungwa huru dzemagetsi, mafungu emagetsi, uye kugadzirisa masaini. Kunyangwe munguva yedhijitari, maredhiyo achiri kukosha—kwete chete kune varaidzo, asiwo kune emergency communications, kudzidza zvemagetsi, uye kuyedza kwevanoda kuita zvemitambo. Chinyorwa chino chinokurukura maitiro ekuvaka redhiyo iyo... Read more

Mazano Ekuvaka Redhiyo neAdvanced Circuitry Kuvaka redhiyo yako pachako ipurojekiti yemagetsi inonakidza uye inonetsa. Kunyange zvazvo maredhiyo aimbove akafanana nemasekete ari nyore akavakirwa patransistor uye zvikamu zveanalog, ikozvino unogona kuvaka maredhiyo ne "advanced circuitry" anosanganisa maRF modules emazuva ano, ma microcontrollers, digital signal processing (DSP), uye maficha akangwara akadai se displays, preset storage, uye connectivity...

Maitiro Ekugadzira Redhiyo Nedhizaini Idiki Pakati pekushandiswa kwezvishandiso zvedhijitari, redhiyo ichiri nerunako rwakaoma kutsiva. Pane mufaro wakasiyana mukutenderedza dhayari, kunzwa "kurira" kudiki usati wavhara nhepfenyuro, wobva wawana chiteshi chaunofarira. Chinonyanya kukwezva ndechekuti unogona kugadzira redhiyo yako nedhizaini shoma - iri nyore, yakachena, uye inoshanda, pasina kushongedzwa kwakawanda. Chinyorwa chino… Read more

Gwaro Rekuvaka Redhiyo neUSB Interface Munguva yedhijitari, redhiyo haisisiri yakafanana nemacircuits akaomarara eanalog, coils, uye ma capacitor makuru ekugadzirisa. Nhasi, unogona kuvaka sisitimu yeredhiyo inoshanda uye inochinjika nerubatsiro rweUSB interface. Pfungwa iyi inowanzozivikanwa seSDR (Software Defined Radio), redhiyo uko mabasa mazhinji ekugadzirisa anotamiswa… Read more

Dzidziso yeKugadzira Nhepfenyuro yeRadio ine MaSensor eFrequency: Nhepfenyuro ichiri mudziyo wemagetsi unonakidza wekudzidza, kunyanya kune vanotanga kutsvaga kunzwisisa zvekutanga zvemacircuit, mafungu emagetsi, uye kugadziriswa kwemasaini eaudio. Munguva yedhijitari, kuunganidza nhepfenyuro hakusi kungo "bata nhepfenyuro chete," asi kunogonawo kuvandudzwa nezvimwe zvinhu zvakaita semasensor efrequency ekutarisa kana kuverenga... Read more

Maitiro Ekugadzira Redhiyo Iine Kugona Kugadzirisa Manual Redhiyo inogona kuita senge tekinoroji "yekare", asi ndipo chaipo painokwezva. Pasinei nekureruka kwayo, redhiyo chishandiso chemagetsi chinosanganisa pfungwa dzemafungu emagetsi, resonance, signal amplification, uye frequency select. Kuvaka redhiyo yako pachako—kunyanya iyo ine kugona kugadzirisa manual—ipurojekiti inonakidza uye inodzidzisa. Nekugadzirisa manual, unogona... Read more

Gwaro Rekuvaka Redhiyo Uchishandisa Macircuits EAnalog: Kuvaka redhiyo uchishandisa macircuits eanalog ipurojekiti inonakidza uye inodzidzisa zvemagetsi. Kunze kwekudzidzira hunyanzvi hwako hwekubatanidza zvikamu, uchadzidzawo kuti mafungu eredhiyo anotorwa sei, anosarudzwa (anogadziriswa), uye obva ashandurwa kuita ruzha. Mugwaro iri, tichafukidza pfungwa huru dzemaredhiyo eanalog, zvikamu zvinodiwa, uye matanho ekubatanidza... Read more

Matekiniki ekugadzira FM Radio yeSignali Yakagadzikana Nhepfenyuro yeFM ichiri nzira inoshanda, inodhura zvishoma, uye inowanikwa nyore nyore yekuteerera ruzivo nevaraidzo. Pasinei nekukura nekukurumidza kwenguva yedhijitari, vanhu vazhinji vachiri kuda FM radio nekuda kwekunzwa kwayo kwakasiyana uye kuvimbika kwayo kana internet isina kugadzikana. Zvisinei, dambudziko guru mukugadzira michina yeFM radio—kusanganisira receiver circuit… Read more

Maitiro Ekugadzira Redhiyo NeShort-Field Transmitter Kuvaka redhiyo neshort-field transmitter ipurojekiti inonakidza, inodzidzisa, uye iri nyore yemagetsi kune vanotanga—chero bedzi uchitevera mirairo nokungwarira uye uchinzwisisa zvipingamupinyi zvekushandiswa kwayo. Neshort-field transmitter, unogona kutumira ruzha (semuenzaniso, kubva pafoni yako kana maikorofoni) kuFM radio iri mumba mako, wobva waiteerera… Read more

Gwaro Rekuunganidza Redhiyo Yedhijitari Nemazvo Akanyanya Kugadzirwa Kuunganidza redhiyo yedhijitari hakusi kungoisa zvikamu pamwe chete nekuibatidza. Mumidziyo yekugadzirisa masaini edhijitari, kunyatsorongeka kwakakosha: kunyangwe kukanganisa kudiki pakuiswa kwezvikamu, mhando yesolder, kurongeka kwedunhu, kana kusarudzwa kwesimba remagetsi kunogona kukonzera ruzha, kusagamuchirwa zvakanaka, kutenderera kwemhepo, uye kunyange kukuvara kweIC.
