OpenLase (a laser project)
by Cestmir Houska 01 Jan '11

01 Jan '11

Hi! I found this project on the 27C3 wiki - apparently the guy will be giving a lightning talk about his project on day 4! Might be worth checking out. http://marcansoft.com/blog/2010/11/openlase-open-realtime-laser-graphics/ Czestmyr

27c3 recap
by Pavol Rusnak 31 Dec '10

31 Dec '10

Ahoj! Uspesne sme sa obe nase posadky vratili z 27C3, ktora bola jednoducho UZASNA! Tym nemyslim len prednasky (ako napr. odpocuvanie GSM prevedene v praxi, prelomenie PS3 klucov ci kopec velmi dobrych lightning talkov) ale aj to, ze sme ziskali kopec skvelych kontaktov ci informacii! Drviva vacsina si velmi pochvalovala nas laserovy projekt (za co patri obrovska vdaka Tomasovi, Felipemu a Czestmyrovi!). Okoloiduci nakreslili laserom na stenu doslova kilometre ciar a nahrali hodiny laseroveho pongu a desiatky brmlabackych nalepok teraz zdobia notebooky ci iny equipment po celom svete (podarilo sa nam dokonca predat 4 tricka! :D). Prekvapivo nemaly zaujem vzbudil aj Kinect (a to sme nemali pripravene ziadne vlastne demo, len sme ho mali vylozeny pri laseri a sem-tam ukazovali RGB a depth data). Par ludi dokonca prislubilo, ze sa v brmlabe urcite coskoro ukazu (napr. jeden typek z rakuskej akademie vied, kde sa hraju s lasermi na uplne inej urovni a pouzivaju na vychylovanie laserov miesto zrkadiel piezoelektricke krystaly, ktore operuju na frekvenciach v radoch stovkach megaherzov - zrkadla typicky desiatky kilohertzov). Par fotiek a videi na zachytenie atmosfery sme nahadzali do nasej chutnej polievky[2]. Hm, ked uz sme pri tom jedle ... Uplna pecka sa podarila haluzne tesne pred nasim odchodom, ked sa za nami zastavil Frantisek - cech, ktory je uz dva roky na cestach po svete, pricom posledne mesiace stravil v USA. Tam sa stal velmi aktivnym clenom znameho hackerspace Noisebridge (uz sme mali od nich na navsteve Mitcha Altmana), kde zalozil pracovnu skupinu Tastebridge, ktora sa zaobera tzv. food-hackingom. Jedna sa o akesi varenie skombinovane s modernymi technologiami a roznymi hratkami s chutovymi poharikmi. Frantisek pride coskoro do rodneho Ceska na cca 3 mesiace, pricom urcite si naplanuje cestu do Prahy a porozprava nam nieco o ich hackerspaci a obaja dufame, ze si aj nieco spolocne ukuchtime, pofoodhackujeme :-) Samozrejme sme sa nezabudli druzit s nasimi spriatelenymi hackerspacmi v Bratislave a Budapesti a zhodou okolnosti pocas 27C3ky sa podarilo Progressbarakom konecne ziskat priestory nie nepodobne nasim (foto[3]), takze snad coskoro budu mat nejake projekty aj oni. Toto ma prave v nespavej euforii napadlo, je toho isto viac, ale potreboval som to teraz rychlo niekam napisat a podelit sa:-) Prosim vsetkych co boli na 27C3, aby si nasli trosku casu a pokusali sa napisat co zazili na konferencii oni na nasu wikistranku[4], staci aj heslovite (na jazyku tiez nezalezi), ked nie ste basnicke crievka, pokusime sa z toho potom spravit nejaky pekny vycuc, na pamiatku a promo :-) [1] https://www.noisebridge.net/wiki/Tastebridge [2] http://soup.brmlab.cz/ [3] tibor.rainside.sk/cukrova/ [4] http://brmlab.cz/event/27c3 S pokrikom Whuiiiiiiii sa teraz lucim a snad sa uvidime zajtra, teda uhm dneska a buchneme si nejaku tu raketu ci sampus o polnoci! Kšššchhhhhht, kšššchht, stick signed off ... -- Best Regards / S pozdravom, Pavol Rusnak <stick(a)gk2.sk>

Silvestr v brmlabu
by Petr Baudis 31 Dec '10

31 Dec '10

Ahoj! Zda se, ze v brmlabu bude na silvestra nejaka akce, ktera ale zda se neni moc nikym organizovana a to mi dela starosti hlavne v souvislosti s tim, ze tam zaroven chteji prijit i nebrmlabaci organizujici se na silvestr.jdem.cz. Zaroven jsme se predbezne po opening party domlouvali, ze v brmlabu uz zadne vetsi party provozovat nebudeme a i v souvislosti s tim mam ponekud strach o brmlabi equipment atd. (pevne doufam a prosim Vas, abyste se kazdopadne chovali zodpovedne a moc se neopijeli :-), zvlaste kdyby nastala treba situace typu "40 navstevniku, 3 brmlabaci". V soucasnosti vim jen od Axe a Sticka, ze planuji v brmlabu byt, a zaroven je ohlaseno min. neco jako 1-10 nebrmlabaku. Kdo jeste v brmlabu budete? Take bych rad poprosil ty z Vas, kdo na Silvestra do brmlabu prijdete, abyste tomu dali trosku nejakou formu, idealne treba udelali na wiki malou event stranecku; kdyby se Vam chtelo nasetupovat v brmlabu na silvestrovskou noc i livefeed, bylo by to uplne skvele! Happy new-year eve hacking, -- Petr "Pasky" Baudis Computer science education cannot make an expert programmer any more than studying brushes and pigment can make an expert painter. --esr

Laser was moved to other room and connected to server there. Results are quite impressive: http://picasaweb.google.com/axtheb/Brmlab Hopefully we can arrange working webcam and some vpn soon... Felippe, do you have access to agoralink/chaosvpn? Using that we can get you link quickly [http://brmlab.cz/project/chaosvpn] And, please, give me commit rights to the repo so I can put my util lib and the rocket game there. Ax

Méri Iksmas

26 Dec '10

Ahojte! Trochu sme sa bavili na IRC o PFkach a zrodil sa mi v hlave napad. Poskadlil som Inkscape a po par minutach som vyprodukoval toto: http://brmlab.cz/_media/brmpf.png (SVGcko je v /promote sekcii). Nie je to uplne dokonale, par zmien by si to ziadalo, ale ako je u nas zvykom, ze docasne veci sa stavaju trvalymi, tak s tym idem do eteru radsej uz teraz. Ak mate cas a chut to zmenit, tak do toho! PS: Prajem Vam a tym vlastne aj celemu nasmu hekrspejsu, nech sa nam v dalsom roku dari, aspon tak ako v tomto, bolo fakt uzasne sledovat to nadsenie a aktivitu! A este aby ste pocas sviatkov nezabudli, ze existuje aj svet mimo pocitaca. Teda aspon ked som ho naposledy kontroloval tak tam este bol :-). -- Best Regards / S pozdravom, Pavol Rusnak <stick(a)gk2.sk>

Samolepky

Ja napr. vobec neviem > kolko ktora stoji a na wiki to prepdokladam tiez nie je ... > (poprosim upravit sekciu Stickers v /promote) Trochu jsme o tom mluvili v utery, ale v brmlabu byl malokdo. Samolepky jsou aktualne v jednom z regalu ve velke mistnosti a je u nich velky papir s navodem. Ve strucnosti, vyrobni cena jednoho archu je 50Kc. Muzete si vzit bud cely arch, nebo si odstrihnout jen podmnozinu nalepek, ktere vyuzijete; nalepky jde z archu bez nuzek odlepovat po jedne, v archu je jedna velka, nekolik strednich a jeste vic malych. Kdyz si vezmete nalepky, dobrovolny dar vhodte do kasicky v bufetu. Samolepek jsme vyrobili celkem 50 archu, 25 bilo-modrych a 25 cerno-bilych. Petr "Pasky" Baudis

Laser Hacking - gitorious repo
by Pavol Rusnak 24 Dec '10

24 Dec '10

Hi Laser hackers! I forked code from Felipe's home repo and put it into brmlab gitorious: http://gitorious.org/brmlab/laser I rewrote most of the code and put it into separate reusable classes (mostly inspired by Czestmyr's work) - these could be later shipped as a separate python module. All examples are in the root and use LaserDisplay.create() factory method. This will read "LASER" environment variable and if it is not set, simulator is created. If it is set to "local" it will try to connect to local USB device. If it contains string in format "remote:host" or "remote:host:port" it will connect to laser server running on machine "host" on default port or "port" port. There are two server - server-hadrware which uses the real hardware and server-emulator which uses emulator. File server-svglaser is used only for WebUI. Two examples are not yet working - pong and spaceship, I will dig into them soon (both are in _depot directory). I thought no one is crazy as I am to commit on Xmas, but I see there are some new commits by Czestmyr, so I will merge them as well. PS: If you are not a member of brmlab gitorious group (which has commit rights to all repos) and want to be added, just send me your gitorious username ... PPS: More precise documentation will come soon(TM) in form of README files and comments in examples. Also I'll put License headers in all source files ... -- Best Regards / S pozdravom, Pavol Rusnak <stick(a)gk2.sk>

Brm! Jak jsem uz zminoval a nabizel na IRC, dost veci se mi zkomplikovalo a tak s nejvetsi pravdepodobnosti nebudu schopen na CCC jet. Byla by tudiz skoda, aby muj listek a ubytovani propadlo. Nabizel jsem to, ozval se tusim bon a JoHnY, ale nic definitivniho. Pokud tedy mate zajem nekdo dalsi, tak se prosim ozvete. f.
