Klubov\u0148u sme otv\u00e1rali spolu s mBorikom, ktor\u00fd pri\u0161iel nahoden\u00fd za gentlemana na nat\u00e1\u010danie v RTVS (\u010di STVR? No kto sa v tom m\u00e1 vyzna\u0165 \ud83d\ude09 ). Pr\u00e1ve pre t\u00fato pl\u00e1novan\u00fa aktivitu sa s nami zdr\u017eal iba men\u0161iu \u010das\u0165 doobedia. Spracovanie nato\u010den\u00e9ho materi\u00e1lu vraj bude nejak\u00fa dobu trva\u0165, tak som s\u00e1m zvedav\u00fd, kedy si tento diel rel\u00e1cie SK Dejiny budeme m\u00f4c\u0165 vychutna\u0165.<\/p>\n\n\n\n

Po pr\u00edchode na miesto konania som rozbalil on-line aparat\u00faru, \u010di\u017ee kameru a notebook, s ktor\u00fdm sa sp\u00e1jame s na\u0161imi kolegami, ktor\u00ed nemohli pr\u00eds\u0165 osobne. Z priestoru MZPRX sa pripojili \u00faplne na \u00favod Martin No.1 a ku z\u00e1veru Martin \u010cern\u00fd.<\/p>\n\n\n\n

Ja som sa pomerne intenz\u00edvne venoval prieskumu dvadsa\u0165eurov\u00e9ho \u201cprojektora\u201d z nemenovan\u00e9ho \u010d\u00ednskeho obchodu.

Zistili sme, \u017ee je to zintegrovan\u00fd Google TV dongle s LED projektorom so slab\u00fdm v\u00fdkonom a rozl\u00ed\u0161en\u00edm. Zariadenie je ako-tak pou\u017eite\u013en\u00e9\u00a0 na streamovanie existuj\u00facich m\u00e9di\u00ed napr\u00edklad z YouTube.

Po p\u00e1r mojich \u00favodn\u00fdch pokusoch sa objavil Ffg, ktor\u00fd n\u00e1m intenz\u00edvne pom\u00e1hal s fotografick\u00fdm a video z\u00e1znamom. Priniesol si so sebou nejak\u00fd X-Box a Apple TV Box.<\/p>\n\n\n\n

Zastavil sa aj novoprich\u00e1dzaj\u00faci Matej, ktor\u00fd ma pred stretnut\u00edm kontaktoval e-mailom.

Loki si po pr\u00edchode rozbalil a za\u010dal sk\u00fama\u0165 tla\u010diare\u0148 Citizen iDP-560CD. Je to ihli\u010dkov\u00e1 tla\u010diare\u0148 ktor\u00e1 umo\u017e\u0148uje tla\u010di\u0165 dvomi farbami. Konkr\u00e9tne v tomto preveden\u00ed to bola \u010dierna a \u010derven\u00e1. Ako papier treba pou\u017ei\u0165 klasick\u00fa rolku so \u0161\u00edrkou 70mm. To nie je ale be\u017en\u00e1 s\u00fa\u010das\u0165 secondhand retro predajov, tak sme sa museli uspokoji\u0165 s doma narezan\u00fdmi papiermi A4 na 3 zvisl\u00e9 p\u00e1siky. Sk\u00famanie za\u010dalo vlo\u017een\u00edm papiera a postupn\u00fdm stl\u00e1\u010dan\u00edm kl\u00e1vesy LF, potom bolo nutn\u00e9 stla\u010di\u0165 kl\u00e1ves SEL, \u010do znamen\u00e1 \u017ee tla\u010diare\u0148 je pripraven\u00e1 na vykon\u00e1vanie pr\u00edkazov posielan\u00fdch z po\u010d\u00edta\u010da Commodore 64 po s\u00e9riovom k\u00e1bli IEC. Pokusmi sme zistili \u017ee poslan\u00edm znaku CHR$(18) bude text invertovan\u00fd a CHR$(20) zmen\u00ed farbu na \u010derven\u00fa, CHR$(17) zmen\u00ed znakov\u00fa sadu na mal\u00e9 a ve\u013ek\u00e9 p\u00edsmen\u00e1, inak s\u00fa to len ve\u013ek\u00e9 p\u00edsmen\u00e1 a PETSCII znaky. Na \u0161ir\u0161ie p\u00edsmo treba pou\u017ei\u0165 CHR$(1). Tieto m\u00f3dy ako napr. inverzia, farby alebo prepnutie znakovej sady platia pre cel\u00fd riadok. \u010eal\u0161ia podstatn\u00e1 vec pri ihli\u010dkovej tla\u010diarni je \u017ee ko\u013ek\u00fdmi ihli\u010dkami tla\u010d\u00ed a \u017ee \u010di je mo\u017en\u00e9 tla\u010di\u0165 \u013eubovo\u013en\u00fa grafiku. Tla\u010d\u00ed sa siedmimi ihli\u010dkami a do riadku sa teda zmest\u00ed 240×7 bodiek. Grafika sa tla\u010d\u00ed cez CHR$(27), CHR$(75), <po\u010det st\u013apcov>, CHR$(0) a n\u00e1sledne X bajtov, pre ka\u017ed\u00fd st\u013apec jeden. Bit \u010d\u00edslo 0 je naspodku, bit \u010d. 6 je hore. Probl\u00e9m ktor\u00fd sme e\u0161te nevyrie\u0161ili pri tla\u010den\u00ed je ten, \u017ee ka\u017ed\u00fd riadok po vytla\u010den\u00ed posunie papier o dva riadky, tak\u017ee napr. QR k\u00f3dy by sme s t\u00fdm e\u0161te tla\u010di\u0165 nemohli. Zdroje ale na internete s\u013eubuj\u00fa \u017ee je mo\u017en\u00e9 riadkova\u0165 iba po jednom riadku a tak napr. vytla\u010di\u0165 hard copy obrazovky. T\u00fato vlastnos\u0165 sme u\u017e nestihli overi\u0165 nako\u013eko tla\u010diare\u0148 za\u010dala \u010dasto hl\u00e1si\u0165 chybu a ve\u013ea kr\u00e1t ani nedokon\u010dila u\u017e overen\u00fa tla\u010dov\u00fa \u00falohu. Vyzeralo to tak \u017ee sa dos\u0165 hriala. Nap\u00e1janie sme mali upraven\u00e9 cez transform\u00e1tor 220V na 110V nako\u013eko bola tla\u010diare\u0148 dovezen\u00e1 z USA. P\u00f4vodne bola prev\u00e1dzkovan\u00e1 s Commodore VIC20. \u010eal\u0161ie pokusy u\u017e v dom\u00e1com prostred\u00ed dopadli e\u0161te hor\u0161ie, preto\u017ee nie\u010do sa stihlo pokazi\u0165 a tla\u010dov\u00e1 hlava sa pos\u00favala maxim\u00e1lne iba jeden znak. Potom sa do poistkov\u00e9ho neba poru\u010dila sklenen\u00e1 poistka 500mA, \u010do signalizuje \u017ee m\u00e1me ve\u013ek\u00fd probl\u00e9m ktor\u00fd si vyp\u00fdta e\u0161te ve\u013ea \u010dasu na rie\u0161enie.<\/p>\n\n\n\n

Otis a jeho syn Alan sk\u00famali dosku Robika – sovietskeho ZX klonu, ktor\u00fa som priniesol na pl\u00e1novan\u00fa diagnostiku, ale nakoniec sme sa na \u0148u iba pozerali, lebo som nezobral n\u00e1hradn\u00e9 \u010dipy a ani dostatok n\u00e1radia. Dosku som potom dodato\u010dne rozbeh\u00e1val po stretnut\u00ed nieko\u013eko ve\u010derov. V\u00f4bec to nebolo triv\u00e1lne a vy\u017eadovalo si vo viac pozornosti ako by sme jej boli schopn\u00ed a zrejme aj ochotn\u00ed da\u0165 na stretnut\u00ed.<\/p>\n\n\n\n

Poobede som tie\u017e testoval obdobu EasyCapu zna\u010dky Tchibo, ktor\u00fa som zohnal na pezinskom bl\u0161\u00e1ku za p\u00e1r drobn\u00fdch – a to doslovne, pani pred\u00e1vaj\u00faca p\u00fdtala 2\u20ac.
