Food hacking base founded at CCC Summer Camp! (Please distribute widely!)
by Frantisek Apfelbeck 04 May '11

04 May '11

Greetings Everyone! We are very happy to announce the creation of a Foodhacking Base at the 2011 CCC Camp this August 10-14. The Foodhacking Base will be part of NeighborCamp, the village hosting the Hackers on a Plane trip. To feed the folks travelling with HoaP, we’ll have a well stocked and well equipped kitchen. Now to plan how we’re going to use it the “hacker way”! My role is to get cool people participating in this endeavour. So if you like cooking, fermenting, distilling or any one of a million things related to food and beverages, please get in touch! I'm already finishing the design of the kitchen and first list equipment list to have a basis for discussion. Once the show starts, I'm responsible for making sure everything goes nice and smooth and on budget. I'll be cooking and fermenting a lot, leading some of the shifts and workshops on every day basis. Your part? Be creative and think of something :-)) Otherwise come and join us, have fun, do some really cool food hacks, nice and simple (we are still missing the go go dancers for the party :-)) gender doesn't matter after twelve no one cares!). So here is the project wiki page and mailing list, sign for it, bookmark it or just pop in! https://www.noisebridge.net/wiki/Food_Hacking_Base_CCC_Summer_Camp_2011 http://lists.hackerspaces.org/mailman/listinfo/foodhacking See you all at CCC, Sincerely, Frantisek (Please distribute to any foodhacking or hackerspace lists you know of so we can get as many folk involved in planning as possible!) PS A bit more info. The deal is that we have a decent budget for equipment and ingredients. Our goal is to prepare food for the roughly 40 Hackers on a Plane (plus guests) at in the NeighborCamp village during the camp. In addition on 11th we will prepare party dinner for “whole camp”. There will be buffet style food at least three times per day, preferably 24/7, with plenty of vegans options all the time. That is what we get, that is what we give. I'm now opening the project to discussion, hopping that people will step up and we will be able to make this event really rock and roll. I'm enclosing a list of activities which I would love to see happening within the food hacking center, please do add what ever you would like to be doing and we will see what happens. I can imagine that we will split the day in shifts and there will be around 6-8 people on the shift, so we can take it easy and have a fun. I should mention that the Hacker on the Plane group is budgeting 10 EU per day per participant for food, so if you are eating with us you should consider contributing in cash or supplies. Nobody will be turned away, but please discuss alternative options with me in advance if money is an issue. I'll do my best to have some great free food and beverages for helpers, give me some time to negotiate there :-)) Have a great time and I hope to see many of you in the kitchen or at least popping in for some treat. Sincerely, Frantisek Algoldor Apfelbeck

Streaming z brmlabu
by Petr Baudis 04 May '11

04 May '11

Ahoj! Jenda vymyslel a pripravil moznost snadneho streamovani prednasek, akci atd. z brmlabu. Ja jsem vcera prepinani streamingu dopsal do brmd, takze nyni jiz uplne kazdy clen muze streamovat dle potreby! Postup: * Hlasite upozornim, ze jdu streamovat. * Vezmu kameru oprenou na stativu u brmbaru a umistim ji, kam chci. * Zapnu kameru (otoci se takovy stribrny cudlik z polohy "OFF" do polohy "AUTO)". * Prepnu na Club Mate panelu bily prepinac. Rozsviti se oranzova LEDka a streamuje se. Notifikace o streamovani vcetne URL se objevi na IRC a odkaz na stream najdete i na http://nat.brmlab.cz/brmd/. K vypnuti streamovani aplikujte inverzni postup. Diky Jendovi i ostatnim, kteri mu pomahali! Dalsi krok bude nasetupovani restreamovaciho serveru na tluste lince a podobne snadna moznost nahravani prednasek nebo treba jen demicek projektu. Ale vseho docasu. :-) Happy hacking, -- Petr "Pasky" Baudis UNIX is user friendly, it's just picky about who its friends are.

Fwd: [edubrm] [GGHC] brmlab summary: edubrm
by Pavel Ruzicka 04 May '11

04 May '11

-------- Original Message -------- Date: Wed, 04 May 2011 06:28:01 +0200 From: Pavol Rusnak <stick(a)gk2.sk> Hi all! See our summary blogpost at: http://www.element14.com/community/people/brmlab/blog/2011/05/04/challenge-… Project name: EDUBRM Summary: Aim of our project was to create an open platform for teaching electronic principles. Our target audience were students of elementary and comprehensive schools interested in this field. The main idea of the project is to provide modular design. One "mother board" can be extended with a set of "shields" which are used for particular scenarios. During the challenge we created three example shields and one debug shield for our purposes. Mother board is based on ARM Cortex M3 chip (more exactly LPC 1343 from NXP Semiconductor), Direct digital synthesizer and Operational Amplifiers. This combination allows us to read 6 analog values from the shields, which can be very low, because they can be multiplied up to 32x. DDS generates frequency from 1 Hz up to 50 MHz in 1 Hz steps, which can be used for generating various signals or alternating current. The first demo shield we create illustrates the creation of electricity using a dynamo and electrodes. These are made from different metals and can be plugged into lemon or a potato. Software reads up voltage and draws a nice graph. Second shield represents a simple DC circuit with a battery, switch and a bulb. Edubrm application can detect whether battery and bulb are present and if the student has pressed the button. It also visualizes which parts of the circuit have power and which not. Third shields can visualize voltages and currents in circuits with coils and capacitors. It can also switch between AC and DC power source so student can easily understand behaviour of these electronic parts while turning the power on and off. Check the following video to get the idea how it works! http://www.youtube.com/watch?v=u662X7ndcCM We also came up with ideas for lots of shields that could be used in other fields than electronics. Sadly, we were not able to implement them in time. To give some examples: * shield with two speakers emitting the same soundwave but with different phase, student can use the microphone to find out that there's no sound in the exact middle of them, application would draw charts of signals to speakers and from the microphone (acoustics) * shield that can read various amplified biosignals, like ECG or EEG (medicine) * shield with dynamo and motor connected through gears, student can inspect the resulting voltage while changing the gear ratio (mechanics) Links: * project wikipage - http://brmlab.cz/project/edubrm * source code - http://github.com/brmlab/edubrm We'd like to thank all people involved in organization of this great challenge! -- On behalf of Hackerspace Brmlab Best Regards / S pozdravom, Pavol Rusnak <stick(a)gk2.sk> _______________________________________________ edubrm mailing list edubrm(a)brmlab.cz http://rover.ms.mff.cuni.cz/mailman/listinfo/edubrm

Prohlidka prazskych kolektoru
by Petr Baudis 03 May '11

03 May '11

Ahoj! Existuje moznost exkurze do kolektoru v prazskem centru - my bysme urcite neco takoveho chteli podniknout, ale napadlo nas, ze by mohlo stat za to, zorganizovat brmlabi exkurzi: http://www.kolektory.cz/index/10_zt.html http://www.kolektory.cz/index/10_zt/10_01_trasa_c.html http://www.kolektory.cz/index/10_zt/10_01_trasa_d.html Trasa C je delsi a asi zajimavejsi, ale drazsi a narocnejsi. Pri plnem naplneni kapacity by byla cena na osobu 300-400Kc, cim mene lidi, tim drazsi. :-) Pokud byste meli o exkurzi zajem, napiste mi prosim (staci soukrome, za tyden poslu souhrn): * Pocet osob * Ktere dny byste mohli (St/Pa/So, casy viz web) * Jake nejvyssi vstupne byste byli ochotni zaplatit * Mate-li trasove preference Exkurze by se nejspis uskutecnila v druhe pulce brezna. Rozsirte prosim informaci i mezi sve zname, at sezeneme dost lidi!

02 May '11

Zdravim ve spolek, Prave jsem dokoncil hybernaci kultur vodniho kefiru a mlecneho kefiru. Obe kultury jsou v novych mediich pri minimalni metabolicke aktivite diky nizke teplote (lednice). Kultury jsou oznaceny s instrukcemi kdy prikrmit. Jakekoliv dotazy ohledne kultur rad zodpovim ci se podivejte na https://www.noisebridge.net/wiki/Recipes_and_Manuals Dnes odjizdim z Prahy a ve ctvrtek letim do Irska, kde budu shanet zbytek financi na zrealizovani projektu Pomoc Japonsku. Doufam, ze to pujde OK neb za to rucim a citim to na "bedrech". Chci byt v Galway, tak to chci poradne roztocit v 091 labs http://091labs.com/ Budu v kontaktu a doufam, ze se s velkou casti z vas uvidim na CCC letnim kempu 9-14/8/2011. Mala perlicka, kterou zatim malo kdo vi. Na kempu budu mit na starosti kuchyni pro Hackers on the plain a jejich Neighbor vesnicku. Udelam maximum pro to, aby se toto misto stalo pravym "srdcem" food hacking celeho kempu, takze se tam urcite zajdete mrknout, bude to stat za to! Diky moc za zprijemneni meho pobytu v Praze, preju vsem vse nej a hodne uspechu v Global Hacker Challenge! S pozdravem, Frantisek PS Kombucha je spolu s jogurtem v lednici take

----- Forwarded message from Vilem Marsik <vmarsik(a)suse.cz> ----- FYI, dnes vecer (21:03) je posledni let raketoplanu Endeavour, mozna posledni let raketoplanu vubec (jeste planuji jeden, ale co vim tak neni uplne jiste zda bude). Primy prenos by mel byt zase na NASA TV. Prehravani v Mplayeru je trochu komplikovane, pro vyssi kvalitu je myslim potreba rtmpdump a trocha hackovani, takze doporucuji nenechavat na posledni chvili.
