Ur\u010dite to pozn\u00e1te. Chcete nie\u010do zauj\u00edmav\u00e9 spravi\u0165 na svojej +2, ale po zapnut\u00ed v\u00e1m k\u013eud nedaj\u00fa \u017elt\u00ed duchovia v obraze.<\/p>\n

<\/p>\n

Na\u0161\u0165astie som pri ka\u017edodennej prokrastin\u00e1cii narazil na zauj\u00edmav\u00e9 video (ZX Spectrum +2 Repair (No. 4)<\/a>\u00a0od JoulesperCoulomb), kde sa nielen dozviete, ako \u017elt\u00fdch duchov vyhna\u0165, ale aj pre\u010do to funguje. A tak\u00e9to vide\u00e1 m\u00e1m r\u00e1d.<\/p>\n

\"Obraz<\/a>

Obraz pred \u00fapravou<\/p><\/div>\n

V skratke, duchovia s\u00fa sp\u00f4soben\u00ed ru\u0161iv\u00fdmi vysok\u00fdmi frekvenciami v jasovej zlo\u017eke. Pozrite si video, je to tam vysvetlen\u00e9 lep\u0161ie, ako by som to spravil ja. Autor navrhuje vyfiltrova\u0165 tieto frekvencie LC filtrom na pine \u010d. 8 obvodu TEA2000.<\/p>\n

\"Sch\u00e9ma<\/a>

Sch\u00e9ma \u00fapravy<\/p><\/div>\n

\u00dapravu som nasp\u00e1jkoval, podobne ako vo videu, rovno na obvod TEA. Nie je to ni\u010d zlo\u017eit\u00e9, vyzer\u00e1 to takto:<\/p>\n

\"Filter<\/a>

Filter na obvode TEA<\/p><\/div>\n

Vo svojich z\u00e1sob\u00e1ch s\u00fa\u010diastok som na\u0161iel najbli\u017e\u0161iu hodnotu kapacity 82pF a t\u00fa pou\u017e\u00edvam. Sk\u00fa\u0161al som e\u0161te prida\u0165 paralelne 8pF, aby som sa pribl\u00ed\u017eil k vypo\u010d\u00edtanej hodnote, ale obraz sa mi potom zdal sk\u00f4r hor\u0161\u00ed. A ako vyzer\u00e1 obraz po \u00faprave?<\/p>\n

\"Obraz<\/a>

Obraz po \u00faprave<\/p><\/div>\n

Obraz je v\u00fdrazne lep\u0161\u00ed. Z textov skoro \u00faplne zmizli duchovia. Nie\u010do je vidie\u0165 okolo r\u00e1mika menu, ale u\u017e nie tak ru\u0161iv\u00e9, ako pred \u00fapravou. Duchovia ale st\u00e1le ost\u00e1vaj\u00fa, je to vidie\u0165 napr. na p\u00edsmene „m“.<\/p>\n

\"Duchovia<\/a>

Duchovia s\u00fa st\u00e1le pr\u00edtomn\u00ed<\/p><\/div>\n

Tu je vidie\u0165, \u017ee Mk\u00e1 s\u00fa rozmazan\u00e9 a je v nich vidie\u0165 n\u00e1znak \u017eltej a modrej. Po sk\u00fasenosti s moj\u00edm gum\u00e1kom som vysk\u00fa\u0161al obraz e\u0161te aj na CRT telke. \u017dia\u013e sa mi nepodarilo odfoti\u0165 obraz na klasickej obrazovke, ale vyzer\u00e1 to tam e\u0161te lep\u0161ie, duchovia s\u00fa naozaj ledva vidite\u013en\u00ed.<\/p>\n

Z\u00e1verom m\u00f4\u017eem \u00fapravu iba doporu\u010di\u0165. S\u00fa to iba dve s\u00fa\u010diastky a obraz sa n\u00e1sobne zlep\u0161\u00ed.<\/p>\n
