Vesm\u00edrn\u00ed lid\u00e9<\/a>, alebo dakto in\u00fd, ale mus\u00edm prizna\u0165, \u017ee ma prepadol pocit,\u00a0\u017ee v tomto \u010dasopise zastal \u010das.<\/p>\nNa jednej strane moje srdce ples\u00e1, \u017ee si zopakujem z\u00e1klady elektroniky, ktor\u00e9 som sa u\u010dil na r\u00e1diokr\u00fa\u017eku, ke\u010f som mal 10, ale st\u00e1le ma prepad\u00e1 my\u0161lienka, \u017ee doba predsa len pokro\u010dila.<\/p>\n
Pre\u010do maj\u00fa autori neust\u00e1le potrebu rie\u0161i\u0165 z\u00e1kladn\u00e9 zapojenie multivibr\u00e1tora s dvomi NPN tranzistormi ako aj v AR PE 04\/2016 na strane 8 dole?<\/p>\n
Pokia\u013e si dobre spom\u00ednam t\u00fato sch\u00e9mu som videl na kr\u00fa\u017eku v knihe od Janusza Wojcziechowskeho Amat\u00e9rske elektronick\u00e9 modely, ktor\u00e9 vydalo v slovenskom preklade vydavate\u013estvo Alfa v roku 1972.<\/p>\n
Neviem sa ubr\u00e1ni\u0165 my\u0161lienke, \u017ee korpor\u00e1cie akosi riadia pr\u00edsun inform\u00e1ci\u00ed be\u017en\u00fdm \u013eu\u010fom a nedovolia rozlet a rozh\u013ead.

Aj v dob\u00e1ch z\u00fariv\u00e9ho socializmu sme dostali mo\u017enos\u0165 zozn\u00e1mi\u0165 sa s najmodernej\u0161\u00edmi technol\u00f3giami aspo\u0148 teoreticky, aj ke\u010f s\u00fa\u010diastkov\u00e1 z\u00e1klad\u0148a na realiz\u00e1ciu zapojen\u00ed v podstate neexistovala.<\/p>\n
Dnes u\u017e \u017eia\u013e zozn\u00e1menie s modern\u00fdmi technol\u00f3giami a s\u00favisiacou te\u00f3riou nie je umo\u017enen\u00e9, preto\u017ee za posledn\u00fdch 30 rokov sa v \u010dasopisoch pre verejnos\u0165 objavuj\u00fa st\u00e1le tie ist\u00e9 zapojenia, ktor\u00e9 si vie ka\u017ed\u00fd doh\u013eada\u0165 v on-line arch\u00edve, kni\u017enici \u010di antivkari\u00e1te. No vyzer\u00e1 to tak, \u017ee niektor\u00fdch \u013eud\u00ed opakovan\u00e9 uverej\u0148ovanie t\u00fdchto zapojen\u00ed dodnes st\u00e1le \u017eiv\u00ed.<\/p>\n
Vrcholom je zapojenie kompatibiln\u00e9 s Arduinom na jednostrannej doske DPS so zop\u00e1r riadiacimi tranzistormi na strane 25 toho ist\u00e9ho \u010d\u00edsla \u010dasopisu (4\/2016). Dnes sa d\u00e1 Arduino mini so \u0161tvorn\u00e1sobnou kapacitou flash k\u00fapi\u0165 za cca $2.50. No napriek tomu sa n\u00e1jde \u201crealiz\u00e1tor\u201d tak\u00e9hoto \u201cprevratn\u00e9ho\u201d zapojenia na \u0161pecifickej DPS.<\/p>\n
Nehovor\u00edm, \u017ee tieto veci \u013eu\u010fom ubli\u017euj\u00fa, ale st\u00e1le m\u00e1m pocit, \u017ee ich neobohacuj\u00fa a nein\u0161piruj\u00fa. Akosi nepos\u00favaj\u00fa dopredu. A to je pod\u013ea m\u0148a z\u00e1sadn\u00fd probl\u00e9m a priestor na n\u00e1pravu.<\/p>\n
Ak chceme omladinu dosta\u0165 do re\u017eimu objavovania, sk\u00famania a zdokona\u013eovania sa, u\u017e nem\u00f4\u017eeme za\u010da\u0165 od multivibr\u00e1tora. Ten asi ka\u017ed\u00fd otec radioamat\u00e9r n\u00e1jde v \u0161ufl\u00edku, aby ho svojmu potomkovi uk\u00e1zal a predviedol v \u010dinnosti. Chce to nie\u010do viac, podobne ako dnes nebudeme predv\u00e1dza\u0165 tri\u00f3dy a pent\u00f3dy – hoci teda digitr\u00f3ny z t\u00fdchto elektr\u00f3nkov\u00fdch bastlov maj\u00fa nie\u010do do seba – dokonca ani 555ka nie je \u010do b\u00fdvala vo svojej jednoduchosti a univerz\u00e1lnosti, lebo m\u00e1me predsa za p\u00e1r checht\u00e1kov STM32, Alteru, alebo in\u00e9ho zvera po ruke, ktor\u00fd stoj\u00ed za zmienku.<\/p>\n
Samozrejme za\u010dneme v\u017edy t\u00fdm blikan\u00edm LEDkou, tak\u017ee sme nakoniec op\u00e4\u0165 pri\u00a0 multivibr\u00e1tore, ale tentokr\u00e1t sa mo\u017enosti u\u017e\u00edvate\u013esk\u00fdch nastaven\u00ed dost\u00e1vaj\u00fa do sf\u00e9ry bez obmedzen\u00ed. Sta\u010d\u00ed zapoji\u0165 fant\u00e1ziu.<\/p>\n
A to je d\u00f4le\u017eit\u00e9 – pochopi\u0165 z\u00e1klad a \u00eds\u0165 \u010falej. Nezosta\u0165 pri Amat\u00e9rskom r\u00e1diu spred 30 rokov, ktor\u00e9 sa \u017eia\u013e neposunulo \u010falej a sch\u00e9my v \u0148om bud\u00fa zrejme aj o \u010fal\u0161\u00edch 30 rokov tie ist\u00e9.<\/p>\n
