Prv\u00e9 tohtoro\u010dn\u00e9 stretnutie v pomerne komornom zlo\u017een\u00ed.<\/p>\n

<\/p>\n

Prv\u00e9 stretnutie v roku 2011 prebiehalo v relat\u00edvne malom po\u010dte \u00fa\u010dastn\u00edkov. Nazbierali sme sa \u0161tyria – Ub880d, Mikezt, Ellvis a ja.<\/p>\n

<\/strong><\/p>\n

Klubov\u0148u som otv\u00e1ral kr\u00e1tko po pol desiatej, rozbalil som n\u00e1\u0161 pr\u00edru\u010dn\u00fd internet (v\u010faka z00movi), TV set, Issue 2, laptop a PC osciloskop.
Odhodlal som sa kone\u010dne nastavi\u0165 pracovn\u00fd bod LMka na Iss.2 tak, aby fungoval spo\u013eahlivo na v\u0161etk\u00fdch TVP. Emitorov\u00fd sledova\u010d je tam osaden\u00fd u\u017e od minul\u00e9ho t\u00fd\u017ed\u0148a, ale samozrejme po zapnut\u00ed obraz nabehol iba \u010diernobiely. Za\u010dalo oblig\u00e1tne kr\u00fatenie trimrami – najprv odporov\u00fdmi, potom kapacitn\u00fdmi.
Na\u0161\u0165astie sa po hodnej chv\u00ed\u013eke podarilo naladi\u0165 stabiln\u00fd farebn\u00fd obraz s ostr\u00fdmi odtie\u0148mi pod\u013ea ZX palety. To som netu\u0161il, \u017ee si to v ten de\u0148 e\u0161te raz zopakujem.<\/p>\n

<\/strong><\/p>\n

Dorazil Ub880d. Spravili sme rozdelenie sektorov stolov – pri okne my dvaja, \u010fal\u0161\u00ed dvaja pl\u00e1novan\u00ed \u00fa\u010dastnici pri dver\u00e1ch. Ub880d vybral PMD-85-2A, ktor\u00e9 malo probl\u00e9m s video a tie\u017e TV v\u00fdstupom.\u00a0
Nasledovala odbo\u010dka v podobe nastavovania sindikatskeho pr\u00edstupov\u00e9ho bodu Asus WL500. Ke\u010f\u017ee som potreboval dosta\u0165 do laptopu nejak\u00fa drobnos\u0165 z netu a moja PCMCIA karta podporuje iba WEP museli sme p\u00f4vodne nastaven\u00fa WPA2 prekonfigurova\u0165. \u013dahko sa to nastav\u00ed, pokia\u013e je \u010dlovek pripojen\u00fd vzduchom, ale ke\u010f ho to WiFi vykopne, nezost\u00e1va ni\u010d in\u00e9 len \u0165aha\u0165 k\u00e1ble. No nave\u013ea sa n\u00e1m podarilo spojazdni\u0165 net tak, aby sme dostali aj IP adresu a mohli sme pokra\u010dova\u0165 v rie\u0161en\u00ed probl\u00e9mu PMD\u010dka. Cel\u00e9 to za\u010dalo t\u00fdm, \u017ee sme si pozreli (na\u0161\u0165astie u\u017e iba na fotke) ako pekne bol odp\u00e1len\u00fd p\u00f4vodn\u00fd IO MH7405 na poz\u00edcii V19. Vyzeralo to tak, \u017ee niekto zapojil na p\u00e4\u0165kol\u00edk s video v\u00fdstupom vy\u0161\u0161ie nap\u00e4tie – zrejme prehoden\u00edm konektorov, ktor\u00e9 doslova rozlomilo IO. Ub880d u\u017e sk\u00f4r tento \u0161v\u00e1b vybral a v doske bol v p\u00e4tici osaden\u00fd nov\u00fd SN7405N od TI. Obraz ale st\u00e1le nechcel nabehn\u00fa\u0165. Pod\u013ea sch\u00e9my sme pokra\u010dovali v p\u00e1tran\u00ed. Najpravdepodobnej\u0161\u00edm kandid\u00e1tom sa javil by\u0165 IO MH7403 (V32), ktor\u00fd m\u00e1 spolo\u010dn\u00e9 v\u00fdstupy do videocesty pripojen\u00e9 len cez di\u00f3dy s V19. Tak\u017ee sme ho vymenili v n\u00e1deji, \u017ee sa situ\u00e1cia zlep\u0161\u00ed, \u017eia\u013e nestalo sa.
St\u00e1le mi v\u0155tal v hlave variabiln\u00fd odpor proti +5V v rozmedz\u00ed 330-630R priamo pripojen\u00fd na pin VIDEO TVP (vi\u010f str. 17 servisn\u00e9ho manu\u00e1lu http:\/\/pmd85.borik.net\/?action=download&did=54<\/a>). Ten limituje horn\u00fa \u00farove\u0148 nap\u00e4tia odporov\u00e9ho deli\u010da, ktor\u00e9ho spodn\u00fa \u010das\u0165 tvoria 4 di\u00f3dy a odpor 100R vo\u010di zemi.<\/p>\n

Prv\u00e9 akcie smerovali k sk\u00fa\u0161aniu viacer\u00fdch SN7405, ktor\u00fdch mal Ub880d zo z\u00e1soby viac. Nakoniec mi to nedalo a vysk\u00fa\u0161al som norm\u00e1lny 6x invertor 74LS04 (nie s otvoren\u00fdm kolektorom, ako m\u00e1 05) na poz\u00edcii V19. Obraz kone\u010dne nabehol, aj ke\u010f s flashom na pozad\u00ed, ale p\u00edsmen\u00e1 boli \u010ditate\u013en\u00e9. \u010ealej sme p\u00e1trali ako fin\u00e1lne vyrie\u0161i\u0165 t\u00fato z\u00e1vadu. Nakoniec padla vo\u013eba na z\u00e1hadn\u00fd odpor. Pripojen\u00edm paraleln\u00e9ho 75R sa objavil pekn\u00fd mierne prebuden\u00fd obraz s osadenou SN7405N ako V19. Fin\u00e1lne sme hodnotu ust\u00e1lili na 110R a obraz bol pou\u017eite\u013en\u00fd ako cez videov\u00fdstup tak aj cez ant\u00e9nu.\u00a0
Preto\u017ee sme nemali in\u00fd 7405 od Tesly, neviem \u010di je nevyhnutn\u00e1 zmena z\u00e1hadn\u00e9ho odporu spojen\u00e1 s in\u00fdm vn\u00fatorn\u00fdm zapojen\u00edm IO od Tesly a od Texasu.
Medzi nami to PMD – napriek tomu, \u017ee u\u017e m\u00e1 obraz – ve\u013emi pou\u017eite\u013en\u00e9 nie je, lebo tla\u010d\u00edtka na kl\u00e1vesnici bu\u010f nejd\u00fa stla\u010di\u0165 v\u00f4bec, alebo sa zasekn\u00fa a nepohn\u00fa. Zase m\u00e1me \u010do robi\u0165 nabud\u00face.<\/p>\n

Pokra\u010dovali sme \u010falej s\u00a0doskou Issue 2 tentokr\u00e1t Mikeztovou z Gum\u00e1ku. Sna\u017eil som sa o obdobn\u00fd v\u00fdsledok ako som dosiahol s\u00a0mojou. \u017dia\u013e vyzeralo to, \u017ee modr\u00e1 zlo\u017eka ch\u00fdba \u00faplne. Podozrenie padlo na cestu B-Y, ale tam vyzeralo v\u0161etko v\u00a0poriadku na prv\u00fd poh\u013ead. Jedin\u00fd kandid\u00e1t preto zostal LM1889. Tak som p\u00f4vodn\u00fd vybral z\u00a0dosky, osadil kv\u00e1zip\u00e4ticu z\u00a0prec\u00edznych pinov lebo sme nemali p\u00e4ticu spr\u00e1vnych rozmerov. Po zapnut\u00ed sa podarilo nastaven\u00edm trimrov dosiahnu\u0165 pekn\u00fd farebn\u00fd obraz so v\u0161etk\u00fdmi zlo\u017ekami. Mike po skon\u010den\u00ed sindikatu ozn\u00e1mil, \u017ee farby nezost\u00e1vaj\u00fa stabiln\u00e9 pokia\u013e je Issue 2 zapnut\u00e9 dlh\u0161ie. \u010eal\u0161ia \u00faloha na nasleduj\u00face stretnutie.<\/p>\n

Ellvis vykonal ve\u013ek\u00fd test AY na Didaktiku M. Sk\u00fa\u0161al Melodik, AY od Zaxona (RWAP), a\u00a0m\u00f4j kombajn. S\u00a0t\u00fdm posledn\u00fdm za\u017eil asi najviac z\u00e1bavy, ke\u010f sa ho sna\u017eil do rozdvojky zbernice zasun\u00fa\u0165 nastojato. Probl\u00e9m, pre\u010do sa za\u010dal tento test bol v\u00a0p\u00f4vodnom Melodiku, ktor\u00fd vysadzoval a\u00a0hral z\u00a0\u010dasu na\u010das o\u00a0nie\u010do vy\u0161\u0161ie. Nane\u0161\u0165astie, ani jeden z\u00a0alternat\u00edvnych vysk\u00fa\u0161an\u00fdch AY interfejsov nechcel s\u00a0M-kom chodi\u0165. Tak\u017ee sme pr\u00ed\u010dinu probl\u00e9mu neodhalili.<\/p>\n

<\/strong><\/p>\n

Na toto stretnutie sme pri\u0161li v\u00a0tri\u010dk\u00e1ch s\u00a0na\u017eeh\u013eova\u010dkami klubu. Teda okrem Mika, toho som vybavil po pr\u00edchode. Ako nesk\u00f4r vysvitlo pri pran\u00ed toho m\u00f4jho, atramentov\u00e1 technol\u00f3gia e\u0161te nedospela do \u0161t\u00e1dia stabiln\u00fdch farieb po vyprat\u00ed a\u00a0natla\u010den\u00e9 logo sa mierne rozpilo. Ellvis napriek tomu zhodnotil, \u017ee je to dobr\u00fd po\u010din, \u010d\u00edm ma pote\u0161il, ke\u010f\u017ee som zop\u00e1r hod\u00edn str\u00e1vil pr\u00edpravou a\u00a0na\u017eeh\u013eovan\u00edm.<\/p>\n

\u00a0<\/p>\n

\u010co sa n\u00e1m e\u0161te v\u00a0klubovni zap\u00e1\u010dilo bol zberov\u00fd papier, kde na vrchu tr\u00f3nil kalend\u00e1r so sporo odet\u00fdmi sle\u010dnami, z\u00a0ktor\u00e9ho sme videli iba jednu p\u00fatav\u00fa stranu, lebo bol \u0161pag\u00e1tom zviazan\u00fd v\u00a0kope. \u0160koda, to demo vyzeralo ve\u013emi l\u00e1kavo.<\/p>\n

\u00a0<\/p>\n

Obed v \u010d\u00ednskej re\u0161taur\u00e1cii n\u00e1s neminul ani tentokr\u00e1t. V tej slovenskej \u010do sme boli iba raz, u\u017e maj\u00fa ve\u010dn\u00fa invent\u00faru a pon\u00fakaj\u00fa priestory na pren\u00e1jom.<\/p>\n

\u00a0<\/p>\n

Skon\u010dili sme tesne po piatej ve\u010der, stihli sme sa pobali\u0165 a\u00a0odprevadi\u0165 cezpo\u013en\u00fdch na vlak.<\/p>\n

\u00a0<\/p>\n

Stretnutie malo op\u00e4\u0165 svoje \u010daro postriebren\u00e9 patinou nostalgie a\u00a0pr\u00edjemnej tvorivej atmosf\u00e9ry.<\/p>\n

\u00a0<\/p>\n

A u\u017e sme aj stanovili pl\u00e1novan\u00fd term\u00edn \u010fal\u0161ieho na 5.2.2011.
