help needed: brmdoor (arduino skillz)
by Petr Baudis 19 Jun '13

19 Jun '13

Ahoj! Pred par dny odesel pocitac, na ktery je pripojeny brmdoor a bezi na nem brmd (IRC interface, status ikonka atd.). Ruza venoval a nasetupoval jako nahradu Raspberry Pi, kde nyni brmd bezi, vyskytl se ovsem problem. Potiz je takova, ze brmdoor byl napsany pro Arduino 0.x a nepovedlo se nam jej rozchodit na Arduino 1.0; aktualni firmware tedy funguje, az ho bude potreba zupdatovat (treba pridat/odebrat kartu), pujde to jen s velkym usilim. Existuji dve moznosti, jak situaci resit: * horsi - rozchodit na raspbianu Arduino 023 nebo podobnou verzi * lepsi - fixnout brmdoor, aby fungoval spravne i zkompilovany pod Arduino 1.x. Problem se projevuje tak, ze brmdoor snima tlacitka a komunikuje s pocitacem, ovsem nekomunikuje s RFID cteckou. Ta komunikuje seriove a pro komunikaci se tedy drive pouzivala knihovna NewSoftSerial. Ta uz pro Arduino 1.0 neni a nahradily ji knihovny SoftwareSerial (zkusil jsem i pridat call .listen()) a AltSoftSerial. S ani jednou z nich vsak cteni z RFID ctecky neprobiha (proste nikdy nevrati metoda available() true) a po cca 20min. se mi nepovedlo zdebugovat proc; bohuzel tomu v nejblizsich dnech nemuzu vice casu venovat. Radi bychom Vas tedy poprosili o pomoc s resenim naseho jednodveroveho problemu. Chcete-li pristup na brmdoor, muzeme Vas tam pridat, anebo si muzete arduino proste pripojit ke svemu notebooku a zkouset flashovat z nej. (Je vsak naprosto esencialni, aby pri Vasem odchodu byla v Arduinu naflashovana funkcni verze s plnou sadou karet!) -- Petr "Pasky" Baudis For every complex problem there is an answer that is clear, simple, and wrong. -- H.

Oculus Rift
by Petr Baudis 18 Jun '13

18 Jun '13

Ahoj! Rad bych se zeptal, zda by se nenaslo par lidi, kteri by byli ochotni se slozit na Oculus Rift: https://www.oculusvr.com/ http://en.wikipedia.org/wiki/Oculus_Rift http://news.cnet.com/8301-17938_105-57579846-1/90-year-old-grandma-rocks-an… Duvody: (i) Je to v zasade asi (vyrazne) nejpokrocilejsi VR headset v cenove kategorii tech bezne dostupnych a dost rad bych s tim provedl par experimentu. Da se s tim vyvadet vselicos az po neco stylu holodeck (s externim snimacem pozice v mistnosti). (ii) Myslim, ze v kombinaci s nekterymi Tomasovymi dalsimi zarizenimi by slo udelat napr. aktivni total immersion zcela oddelenou od fyzicke reality (telo nedela temer nic, pracuje jen mozek). To bych si rad vyzkousel. :) (iii) Half Life 2. Caveats: (i) Cena vcetne postovneho, DPH a prip. odpustku ceske poste: $500, tzn cca 10kKc. Nechci si to kupovat sam, protoze to je celkem draha hracka a rozhodne to nebudu vyuzivat kontinualne. Idealni skupina pro nakup, abychom neplatili moc a zaroven se o to (dlouhodobe) moc neprali, by asi byla 3-5 lidi. (ii) Linuxova podpora zatim neni oficialni, ale aspon lowlevel uz se to umi: http://renderingpipeline.com/2013/05/using-the-oculus-rift-on-linux/ https://developer.oculusvr.com/forums/viewtopic.php?f=20&t=1294 (iii) Nosite-li bryle, nebude to moc pohodlne; jak moc pouzitelne to bude bez bryli mi neni jasne. Prinejhorsim bych kvuli tomu osobne asi i poresil kontaktni cocky. (iv) Chcete-li do toho se mnou jit, videl bych podminku, ze pokud se to nekomu povede znicit nebo vazne poskodit, koupi obratem **ze sveho** novy. Zvazte pojisteni zodpovednosti. Petr "Pasky" Baudis

[Bubenská 1 21.6. od 12h do 17h natáčeni_serialu_Clona]
by Petr Baudis 17 Jun '13

17 Jun '13

----- Forwarded message from Jiří Boch <JBoch(a)tvoeurope.com> ----- Dobrý den vážení uživatelé objektu, Rádi bychom Vás informovali o natáčení seriálu ČT v objektu a požádali o maximální omezení provozu a parkování na dvorech objektu v pátek dne 21.6.2013. Popis akce a přání ČT : Natáčení série pro Českou televizi Clona režiséra Tomáše Řehořka se uskuteční na prvním parkovišti za bránou (to před brmlabem, pozn. paskyho) a poté v průchodu a na druhém parkovišti. Scéna je taková, že naši herci představující kriminalisty vycházejí z budovy a jdou ke svým zaparkovaným policejním autům na dvoře. Tím pádem bychom potřebovali dvory mít co nejvíc vyparkované (nelze riskovat, že v půlce natáčení někdo přijde a s autem odjede), zároveň také neobtěžovat tyto lidi našim natáčením a umělým deštěm. Natáčení scén v pátek 21.6. je od 12h do 17h. ..snip.. ----- End forwarded message -----

your inputs needed for my article about hackerspaces for TheNextWeb
by Pavel Curda 14 Jun '13

14 Jun '13

Hi, I kindly ask you to fill in this 3min form<https://docs.google.com/forms/d/1xCx9UHJo_x69ce-BhoUPbXgn-lqXDPqca52o493Gj6…>. Pls help me with my article about hackerspaces for TheNextWeb - thenextweb.com/author/pavelcurda/ I asked 15 hackerspaces from this Hackerspaces.org list<http://hackerspaces.org/wiki/List_of_ALL_Hacker_Spaces>. I will mention some answers in my article + interview with Denisa that I have so far (below] I expect your answers before June20 the form - https://docs.google.com/forms/d/1xCx9UHJo_x69ce-BhoUPbXgn-lqXDPqca52o493Gj6… thanks, Pavel Curda www.thenextweb.com/author/pavelcurda/ Who is Denisa Kera? Something of a nomad with a cause. I travel around the world to visit and work with hackerspaces, Do-It-Yourself biology (DIYbio) labs and various other forms of grassroots citizen science movements. As a researcher, I’m curious to understand what is the best way for a society to interact with, adopt and integrate emergent technologies. I like these spaces, because they let everyone understand and take part in the process of designing, tinkering and playing with various ideas and technologies. I’m also excited about the prospects of such alternative R&D structure to support research in the developing countries, such as Indonesia or Nepal. In my day job I teach mainly stuff around innovation and design at the National University of Singapore, but I’m also an active member of the Prague based hackerspace, Brmlab.cz, supporter of the global network for open biology, Hackteria.org, and this new amazing network of mobile kids hackerspace, HacKIDemia.com. I’m also active in Tokyo, Singapore, Yogyakarta, Kathmandu and Shenzhen with various small projects from open science to open hardware. This summer I’m mapping the hackerspaces in the Balkans and becoming more curious about various initiatives in the Caucasus region. Why are you crazy about hackerspaces? The hackerspaces attract the most interesting people you can meet in a city, the pragmatic visionaries, who are not afraid to take any challenge, but jealously protect their autonomy and freedom. They actually preserve the original mission of the universities, which is academic freedom enabling citizens to develop skills necessary for taking an active part in the public life, the so called “artes liberale” – liberal arts or knowledge, which sets you free. Nowadays it means not only law and rhetoric, but also knowledge of science protocols, programming, hardware hacking, and this is the best place to gain such knowledge and skills on your own terms. Then you can make informed decisions on stuff like GMOs, or be able to set up an ad hoc, secure and independent network during acts of civil disobedience. Rather than expecting the government or some NGO to protect you rights, you are part of a small, resilient and independent community, which can deal with variosu situations, such as the ones we see now in Istanbul, but also disasters, such as Fukushima or the flooding in Prague. Groups of geeks empower citizens to get independent data, and you can see such projects not only in Japan with radiation http://www.safecast.org/, Europe with CO2 and dust monitoring www.kanarci.cz, but also in Indonesia with water http://lifepatch.org/. I admire these projects, they enable people to build sensor networks for sharing data about their environments, but I’m personally exploring more artistic and even science fiction themes. What drives people like me to these places is well summarized by a friend from Tel Aviv hackerspace, Yair Reshef ‘I tell ppl that in hackerspaces we don't *start* anything. we are here to fail. gracefully if possible. completed projects tend to showoff. people always look for the product. a goal embodied in an object. it should be effortless. effortless technology. being in the flow with the right tools and nothing better to do.’ Most of my projects are in some perpetual gamma rather than beta version, they are graceful failure, which I like to repeat and come back to. Can you give us some examples? With the Fablab Yogyakarta in Indonesia and Hackteria.org we hacked a mobile food truck and turned it into molecular gastronomy lab performing this posh cuisine on the streets of Indonesia, testing and showing how simple equipment, such as webcams can become microscopes. It is developing into a project supporting open hardware solutions for cheap lab equipment, but who knows, we may just continue in the mobile food truck fetish ideas. Last year, I also scanned my brain in London and performed “brain uploading” over Dropbox and Facebook to use these fMRI data in Prague for a workshop on data liberation for citizen science project. This will eventually develop into a cloud solutions for such citizen science projects thanks to Ivan Vanzaj from Singapore hackerspace, but I’m also excited about the brain hacking activities in Brmlab.cz and the work of Peter Boraros on TDCs there. This is just to give you some idea how fluid and collaborative these projects are. I also regularly take part in fluorescent organisms night hunt in Swiss mountains, last time it was with hacked Indian spiritual chants automata, and I hope soon to take part in the Brmlab’s hunts for meteorological stations. This is amazing, you are catching hardware like a prey and then developing it into something different, you make these thropheis you hunted into open hardware projects, you liberate it! What do people in hackerspaces need? Do they have commerce abitions? Do they need marketing / business developmenmt / sales support? They are happy without money guys? Now seriously, hackerspaces are so far the best response to the criticism that the pace of our technological progress doesn’t follow our moral and social progress… that somehow we are creating things and technologies, which do not make us better as individuals nor they help communities. The typical geek will never argue about this, she will find this whole discussion ridiculous. She never knows what she is building, she doesn’t make a distinction between scientific and social value, she accepts uncertainty and likes to explore the possibilities. She trusts the global community of geeks and enthusiasts who will test and take part in her adventure and challenge her and then they will collectively and tentatively decide on the next step. These spaces are democratic to their core, innovation becomes constantly evolving collective experimentation through tinkering and testing rather than a big theory of social order or some scientific breakthrough, disruptive technology etc. Hackerspaces are my playground or special zone, where I go to dream, where I feel free to test various crazy ideas around emergent technologies: right now I’m curious about microfludicis and lab on a chip technologies and how to use them for a puppetry show with small organisms, before I was looking into food applications, I’m still an advocate for open biodata and I’m interested in various forms of sharing biodata (fMRI and not only DNA), and in the most active project right now we are trying to connect open hardware with traditional crafts in Japan. What is great for me as a designer in these hackerspaces is that I get to understand and test how these technologies will work in various cultural and social contexts. I do work a bit also on serious issues such as models and infrastructure how to support research in developing countries through DIYbio and hacker culture, and then biosafety and biosecurity codes of conducts for DIYbio and citizen science projects. Future? This year I’m often in Shenzhen where I follow the open hardware scene thanks to my hardware gurus, Bunnie Huang, who is setting up an amazing summer school there, and David Li from Shanghai hackerspace, and this amazing young muse and researcher, Silvia Lindtner, who infected me with a love for so called shanzhai phones, creative, DIY, cheap and crazy mobile phones. In Tokyo together with Jan Rod and Charith Fernando from Inmojo.com we are about to launch the Totematons.org, project where we are trying to look into how to support traditional artisan techniques with custom made printed circuit boards and open hardware and define some form of hardware artisanship, which will support old rituals with new technologies. I’m also preparing a workshop on open hardware for farms with Sakar Pudasaini from Karkhana.asia, an amazing hackerspace in Nepal, and I’m trying to be in Yogyakarta as much as possible because that is the most interesting DIYbio science thanks to HONF and Lifepatch.
