Projekty
by Petr Baudis 24 Nov '10

24 Nov '10

Ahoj! Trochu jsem se probiral strankou s projekty a nektere jsem prehazel do jinych kategorii, kde imho lepe vystihuji realitu. Take jsem ze seznamu odstranil projekt makerbot (redundantni s reprap) a hlavne projekt ACT (ktery uz vubec nepouzivame, veskera koordinace zvelebovani prostoru probiha jinymi kanaly a neni jasne, co by se dal na strance projektu melo dit). Dovolil jsem si projekt tool_lending trochu upravit a vic nasmerovat na Blackovu implementaci U.HELP, jejiz funkcni kostru uz ukazoval na predminulem meetupu. Zaroven jsem prekopal Project Kerberos. Asi bych si mel i zamest pred vlastnim prahem a zaktualizovat info o svoji suite projektu (vetsina nestoji uplne na miste) - coming soon. :-) -- Petr "Pasky" Baudis The true meaning of life is to plant a tree under whose shade you will never sit.

Zdravim! Psal jsem Felipe Sanchesovi (to je ten typek, co dela remake pinballovyho stolu z hry Pinball Fantasies), abych na nej mel kontakt v pripade, ze bude pri staveni naseho pinballovyho stolu potreba pomoc od zkusenejsiho. Muj projekt ho zaujal a rikal, ze by se mozna nekdy v listopadu i prijel podivat do brmlabu. Konverzaci preposilam, abyste byli v obraze.

I would love to help you on whatever design you choose to build/create. But I would be extremely happy if you chose to build on of the other pinball fantasies table layouts :-) In the future I'd like to design a fully free (as in freedom) design for a pinball machine. But I have decided to start by building a machine based on a pre-existent layout because I knew that pinball building is a complex project and that designing a good layout demands a lot of knowledge, so I thought I should first learn how to build and then in a future project try to learn how to design a good playfield. It is not easy to master everything at once, so I preffer to make it in 2 complementary steps. > > As for your visit, I'm sure that we could work something out if you'd be > interested. yes, perhaps.

Vracim se ke "svemu ukolu". Mam tu informaci o tiskarne/papiru... Mame tu HP DJ Z6100ps, je to 60" masina. Zere to i 42" papir C6569C (heavy weight coated paper) nebo 24" coz je C6029C (same spec.). Zere to asi i listy, ale my to mame postaveny v konfiguraci pro roli. Takze listovy papiry bych do toho ted strkal nerad. Cenove je to asi takto: C6029C < 800,- Kc C6569C < 1300,- Kc Samozrejme, zere to i jakykoli jiny, drazsi i levnejsi papiry. Ale ten co atm ted je, ten ze ktereho jsou ty vytistene vzorky, to je C6029C. BH

(Idealne este pred utorkovym meetupom). Dakujem vam! ============================== Takze popis, aby bolo jasne co myslim tymi polozkami. Snazte sa byt kreativni (i ked to nie je vzdy lahke) a majte na pamati ze vyplnate profil svojho 8-bitoveho hrdinu, takze popustite svoju fantaziu. :) a) je to vas username co pouzivate na wiki b) mesto odkial pochadzate + stat ak to nie je CR c) + d) toto maju byt 2 kratke vety ktore vas vtipnym sposobom popisuju a mali by vyplyvat z toho co bezne radi robite (idealne v anglictine ale cestinu a slovencinu prelozit zvladam :D) priklady co ma teraz napadaju: (stick) Will install openSUSE on your laptop when you are not looking.

Kalendar
by Pavol Rusnak 21 Nov '10

21 Nov '10

Ahoj! Vdaka joeovi mame teraz na wiki (sekcia Events) pekny prehladny kalendar. Funguje jednoducho, ale pre istotu popisem ako pridat novy event: 1) v lavom menu vyberiem Events 2) dam Edit page 3) v sekcii Upcoming najdem zoznam (riadky zacinajuce dvoma medzerami a hviezdickou) 4) okoliteho html kodu sa nedotykam :D 5) pridam polozku v niektorom z tychto tvarov: * dd.mm.yyyy [[event:meno_mojho_eventu]] * dd.mm.yyyy - dd.mm.yyyy [[event:meno_mojho_eventu]] * dd.mm.yyyy hh:mm [[event:meno_mojho_eventu]] * dd.mm.yyyy hh:mm-hh:mm [[event:meno_mojho_eventu]] Prva moznost vytvori event na dany den, druha moznost na viacere dni, tretia moznost na konkretny den a hodinu, posledna na konkretny den a casovy rozsah. 6) kliknem Save, na stranke sa v kalendari zobrazi moj odkaz cervenym 7) kliknem na odkaz a a tym vytvorim novu stranku s podrobnym info o mojom evente. Dolezite je aby stranka obsahovala ako prvy riadok ====== Super udalost roka ====== Tento nazov sa potom objavi nielen ako nadpis stranky ale aj v kalendari miesto kanonickeho event:meno_mojho_eventu. Snad je to zrozumitelne a ak nie, tak napiste :-) PS: iCal/RSS export plugin zatial nema ale mozno ho raz nakodime/nakodite :-) -- Best Regards / S pozdravom, Pavol Rusnak <stick(a)gk2.sk>

Kinect
by Pavol Rusnak 21 Nov '10

21 Nov '10

Ahoj! Pre tych, co nesleduju dianie okolo Kinect. * Kinect je Xbox ovladac/snimac od Microsoftu, ktory okrem obrazu (640x480@30Hz) snima aj hlbku resp. vzdialenost danych bodov (320x240@30Hz), okrem toho ma v sebe este 4 mikrofony a vie sa natacat * ako to uz byva, Microsoft zasifroval USB komunikaciu, aby sa dalo zariadenie pouzivat iba s jeho konzolou * Adafruit vypisali odmenu $2000 za vytvorenie open-source ovladaca, neskor tuto odmenu zvysili na $3000, kvoli vyhlaseniam Microsoftu :-) * tuto odmenu vyhral pred dvoma dnami Hector Martin Cantero - blogpost: http://is.gd/gX86b - source: http://git.marcansoft.com/?p=libfreenect.git * Matt Cuts sa rozhodol vytvorit dalsi contest o 2x $1000 za vytvorenie najlepsieho projektu pouzivajuceho Kinect, resp. o vytvorenie frameworku pre jednoduche programovanie Kinectu - http://www.mattcutts.com/blog/open-kinect-contest/ - niektore jeho napady su dost dobre :-) * zariadenie samotne je dost lacne (150$, u nas az 4000 Kc :-(), mozno sa este v buducnosti objavia nejake DIY verzie - suciastky vyjdu cca na 60$ - http://www.adafruit.com/blog/2010/11/11/kinects-bom-roughly-56-teardown-fin… , ale to skor pochybujem A preco to cele vlastne pisem? Chcem sa spytat, ci by bol zaujem jeden Kinect zakupit do brmlabu. Ak by sa nasiel dostatocny pocet ludi, ktori by mali zaujem s Kinectom experimentovat, mohli by sme to zacat riesit (tj. financie a odkial ho zohnat) ... -- Best Regards / S pozdravom, Pavol Rusnak <stick(a)gk2.sk>

Prednaska ARM jako MCU
by b00lean 20 Nov '10

20 Nov '10

Ahoj, Napadlo me ze bych mohl udelat pro brmlab prednasku na tema "ARM jako MCU". Shrnovala by me zkusenosti, ktere jsem nabyl pri praci na projektu Elbow kde pouzivam AT91SAM7S256. Ucelem prednasky by melo byt usnadnit praci tem co by chteli v budoucnosti vyvijet zarizeni postavene na ARMu ci rozsirit obzory jak se daji delat zarizeni mimo arduino svet. Priblizna agenda (chtel bych se drzet maximalni delky 60minut): 1. ARM core - typy procesoru arm 2. ARM assembler - jen zakladni odlisnosti instrukcni sady od jinych mcu/cpu 3. AT91SAM7S256 - hw featury + sw knihovny 4. Komunikace s okolnimi periferiemi (I/O) 5. FreeRTOS - featury a pouziti 6. ARM+JTAG+openocd+GCC+FreeRTOS+Eclipse+GDB - "pohodlny" software stack, ktery pouzivam pro vyvoj a debugovani nad ARMem Kdo by mel zajem se takove prednasky zucastnit tak se prihlaste na odkazu nize a v pripade dostatecneho poctu lidi bych prezentaci zrealizoval. http://www.doodle.com/mpwvzvep67466urp Cau, b00

19 Nov '10

Brm! Na twitteru satai nabizel za odvoz stul a skrin odnekud z Holesovic. Pasky naznacil, ze by se nam neco takoveho hodilo. Myslite ze bychom sehnali nejake auto a lidicky, kteri by byli schopni a ochotni to nalozit a dovezt do brmlabu? Ondro, muzes nam poslat fotku/fotky toho nabytku, abychom vlastne vedeli, jak to vypada a jestli to tedy upotrebime? Je ten stul nejak rozumne pevny? Diky, fissie

Need advice - spinani LCD pohybovym cidlem
by Petr Baudis 19 Nov '10

19 Nov '10

Ahoj! Mame doma v kuchyni goistickou televizi a rad bych, aby se jeji monitor (obycejne LCD) zapnul vzdy jen, kdyz se ma na ni kdo divat. I koupil jsem pred casem v Baumaxu klasicke PIR cidlo (urcene primarne na venkovni osvetleni, ma umet spinat az 1200W zarovky) a ted jsem se konecne dostal k tomu, monitor pres nej pripojit - jednoduse jsem ho dal na 220V napajeci kabel mezi monitor a zasuvku. V cidlu cvaka nejake relatko. Ale narazil jsem na problem - kdyz cidlo monitor sepne, v prubehu inicializace mu vyrazne zakolisa jas v power ledce a ve chvili, kdy se rozsviti podsviceni, uz jen sleduji, jak zbytky obrazu zaleva bily flek (uz jsem to videl driv treba na prehrivajicich se noteboocich, asi zakolisani napeti neunesla ridici elektronika). Tenhle symptom se navic projevuje i v pripade, ze monitor zapnu az pote, co rele seplo. Bez cidla samozrejme funguje monitor v poradku (alespon fungoval do chvile, nez jsem na jeho power cable cidlo namontoval). Vazne mi nejde do hlavy, cim by to mohlo byt. Nemate nekdo nejake napady?
