29 Aug '13

Ahoj, podařilo se mi prolomit korekční kódy pro meteosondy. další plán je následující: zkusit vydírat autora Sondemonitoru že je vyměníme za rovnice na přepočet měřených hodnot na teplotu/tlak ... (stejně je budem chtít publikovat, ale proč to nezkusit :) Pinky.

BladeRF
by Jan Hrach 22 Aug '13

22 Aug '13

Ahoj, do brmlabu přibyl z grantu přispěný softwarově definovaný transceiver BladeRF - kouzelná destička, která umí všechno od příjmu televize po emulaci GPS satelitu. Najdete ho v radiolabu. Upozorňuji, že se jedná o delikátní aparát. Zejména jej prosím nepřipojujte ke stávajícím radiolabím anténám, není ještě vyřešena ochrana a už nám pár SDRek shořelo. Happy hacking -- Jan Hrach, http://jenda.hrach.eu/ GPG CD98 5440 4372 0C6D 164D A24D F019 2F8E 6527 282E

21 Aug '13

Ahoj, budu nakupovat na mdfly.com. Primárně mi jde o modul, který bez řečí přehrává z SD karty mp3 soubory ( http://www.mdfly.com/index.php?main_page=product_info&cPath=9_53&products_i…, 10USD , už dva úspěšně používám). Obchod ale nabízí i další pěkné věci - RFID karty, čtečky, FPGPA programátory, serva a úchytky na ně. Pokud někdo chcete nějakou vychytávku koupit, a podělit se o poštovné, dejte do neděle vědět. vatoz , Václav Černý

Brmbar
by mrkva＠mrkva.eu 21 Aug '13

21 Aug '13

Brm! jeden ze závěrů dnešního meetupu je ten, že problém s mizejícími penězmi/zbožím z brmbaru nezmizel (za 14 dní zmizelo nebo bylo zmizeno cca 600CZK). Jen připomínám, že stále platí pravidlo že nečlenové nesmí být v brmlabu sami. A možná by nebylo od věci, do doby než vymyslíme nějaké lepší opatření (mimochodem, nápady?) dávat pozor na nečleny aby se v prostoru brmbaru nepohybovali sami (pořád předpokládám že to nedělá žádný člen). Díky Mrkef

brmbar
by Jamison Young 21 Aug '13

21 Aug '13

I'm reading all these comments about the bar through translation. So maybe I have it wrong. To me it seems that the situation your in, is caused by the lab just wanting the situation to stay as it is. How many club mate bottle have been drunk since the lab opened, multiply that by 7 crowns a bottle. Why not ask the distributor how many he has delivered? Now you also get an extra crown per bottle. Where are all the projects created from the brmbar? it might just be that all the profit has been drunk and eaten over time... Its only really in the last months that you have started to have some sort of accounting system that functions. I also don't really understand why you have a system where people can bring their own product they buy into the lab...you have enough people that use the space to get distributors to bring product. i don't understand why people need to credit their account, why not just pay in cash as you buy the products. So much complexity is only going to create creative accounting. best run the bar like a business, and work out how to manage the situation with an accountant. growing pains that need to be solved..I tried to bring product into the space, and it had to be brought to the attention of every member...

Brmlab Brmbar
by Jamison Young 21 Aug '13

21 Aug '13

Hi, The cupboard next to the downstairs space that brmlab already rents, its possible that Brmlab could rent this space from Orco, as i really don't need the space that much. I can change my postal delivery point to the stairs of the current space I rent. Its around 4 square meters. One idea might be to store stock rather than have cash. consider also that if Brmlab buy large quantities, the price is (should) be better. If you need cash for a project, have an event and sell stock...might be easier to regulate the stock better each week from a separate secure space.. jam

Rezim vstupu do budovy
by Petr Baudis 15 Aug '13

15 Aug '13

Dobry den, radi bychom se zeptali, jaky je aktualne rezim hlavniho vchodu do budovy ve vecernich hodinach, zaznamenali jsme totiz, ze se hlavni vchod v poslednich dnech zamyka mnohem vice nez dosud (alespon v utery to tak bylo). Nasi clenove a navstevnici typicky predpokladaji, ze vratnice funguje jako dosud a tento nesoulad s realitou nebo mozna nepochopeni vytvari oboustrane neprijemne situace. Jde o docasnou zalezitost nebo trvalejsi zmenu? Ocenili bychom, kdyby takove zmeny byly predem najemnikum ohlaseny, abychom se podle toho mohli zaridit, takhle to bylo pro nektere neprijemne prekvapeni. V souvislosti s tim by nas zajimalo, kde je v objektu umisten pozarni vychod a jak je zajistena jeho prostupnost v pripade nouze. Dekujeme, Petr "Pasky" Baudis et al.

Dnes bych rad udelal ochutnavku mlecneho kefiru co jsme zacali vcera, minimalne jeden typ s ovocem. Napoj z vodniho kefiru bude jiz doufam take hotov, dale bych rad pripravil nejake crostiny neb mate gril a kdyz najdu nejakou panev na smazeni, tak by jsme mohli udelat zelnaky ze zeli co Stevko vykvasil v misntim podzemi (muzu zkusit i ten gril, uvidime). Rad bych pridel jednu ci dve pomazanky, takze by to mela byt plejada. Pokud nekdo prinese jablka ci banany, tak mam cca 2 kg belgicke cokolady od osazenstva Belgium vesnice z OHM2013, tak si muzem hrat, Cestimer nedavno delal nejaky dabelksy experiment s chili ... :-) Mejte se prima a budu se tesit, zacatek bych dal zase tak kolem te sedme vecer do pozde :-) Jinak upozornuji, ze v patek odpoledne v 17:00 vyrazim smer Amsterdam a pak Korea, takze je treba vse rozvazne poklidit at tu nezbyde zadna "biologicka bomba". Dnes chci trochu pred workshopem trochu poklidit podlahy.

Fwd: campzer0: call for participation
by Pavel Ruzicka 15 Aug '13

15 Aug '13

we have a location and a call for participation: http://camp.hsbp.org/2013/zer0/#cfp you guys, this will be soooo cool. come and join us ---------------------- Call for Papers Dates and Deadlines Submission deadline: 2013-08-25 00:00:00+0200 Notification of acceptance: 2013-08-31 Presentation Language: English Submission Email: cfp(a)camp.hsbp.org Topics: should cover mostly technical presentations focusing on - breaking and building infrastructure and on - current ethical issues Location: Fort Monostor, Komárom, Hungary Contact: - Twitter: @campzer0 - E-mail: campzer0(a)hsbp.org - IRC: #campzer0 @ IRCnet (the following shamelessly adopted from the 30c3 CfP) The "Hungarian Autonomous Center for Knowledge and friends" runs the camp with the help of self-organized volunteer teams and on its own funds. We are proud of this and we are looking forward to copy the inspiring example of independent self-organizing as championed by the organizers of the Chaos Communication Congress and Camps. We regard this event as one of the few places where a global exchange using the creative-critical approach to technology and society is possible without censorship. We are not providing a stage to secret services or other state organisations. However, based on our concept and on the fact that work is done on a voluntary basis, a thorough advance screening of participants and speakers is not possible. It goes without saying that everyone attending the camp should be treated with respect and consideration. A significant proportion of delegates and speakers value their privacy, the integrity of their own data and their photographic likenesses. Those who attach less importance to personal agency in these matters are in a stronger position. We therefore ask them to respect the feelings and wishes of others. Submission Guidelines For talks and workshops Please send us a description of your suggested talk that is as complete as possible. The description is of particularly importance to the selection, so please ensure it is as clear as possible. Quality takes precedence over quantity. Due to the non-commercial nature of the Camp, presentations which aim to market or promote commercial products or entities will not be entertained. As it is possible that that there will be multiple submissions about the same topic, please show us exactly why your talk should be part of the camp. Please write something about yourself, your environment and your motivation. It does not matter if the talk has been held at another conference, All it has to be is up to date. Talks should be no longer than 45 minutes plus 15 minutes for question and answers. Longer slots are possible in principle. There are 20-minute slots as well. Please tell us the proposed length of your talk at the time of submission. For projects, installations and other fun things We have a lot of space (64.000m^2) and we are open for crazy and surprising stuff.

progress on brewing with kombucha culture
by Frantisek Apfelbeck 15 Aug '13

15 Aug '13

Hi to all, I just wonder how are you kombucha doing? I hope that they are well and they prosper. For the ones who got their cultures on the OHM2013 and prepared 0.5 l of brew with 10% (w/v; 50 g) of light brown or dark brown cane sugar and 0.5-1% (w/v; 5-10 g) of black tea, the time of making larger batch is coming. For the ones who got their SCOBY's recently, I recommend to make the first batch as described above and let it ferment for 10-14 days so the mother (SCOBY) gets thicker and is more easy to work with, the brew however is too acidic to drink but should be feasible for vinegar. The SCOBY harvested after such period should be fine to ferment up to 5 l of brew easily, it will take few weeks of brewing till the mass of the SCOBY stabilizes and the performance is more repetetive. For the next brew I would suggest probably 5 l wide mouth jar and aim for culture volume (Vc) 4 l. The concentration of ingredients for the growing media (brew) should be around 5-6% (w/v; 200-240 g) of cane sugar (light brown or dark brown) and 0.5-1% (w/v; 20-40 g) of black tea. This would leave you with +- 1 l of air in the container, still the culture has to be protected by some cloth so it can breath but the insect can not get in - make sure to fasten it by some rubber string. If fermented at room temperature ranging from 20-25C, you should be ready to harvest between 5-8 days optaining a lighter style of kombucha, suitable for drinking 0.5-1.5 l per day of consumtion should be OK. You need to make new media, transfering the mother (SCOBY) in it and straining and bottling the old brew. That is a good moment for adding variety of flavours, be careful about the ones with high concentration of sugars - they will go really fizzy and can run from the bottle or even explode. Simple one (whic I truly dislike but many love) is nettle flavour. You get either fresh or dried nettle leaves and make a strong infusion by boiling (for 4 l, I would suggest 0.5-1% (w/v; 20-40 g) of leaves simmered for 5 min or so in low volume of water, maybe around 200-300 ml). Strain the nettle out and add the liquid to the brew, do not worry about the temperature the total volume will buffer it. When happy with flavour I recommend to strain the brew completely through fine sieve so you get rid of small pieces of SCOBY which are not liked by many, also it slows down the creation of the SCOBY's in the new bottles. If you like your drinks to be fizzy, I recommend to bottle them bit sweeter than you like, make sure the lids are really tight so the carbon dioxide which is being produced doesn't escape and keep them fermenting at room temperature for one to three days (good trick is to bottle one bottle in plastic, so you can check by touching what is the pressure, it is hard to say if all the bottles are in glass). When happy with the fizzines, transfer the bottles to cold (below 6C) and keep them maturing for week at least to improve the flavour, but you can drink directly too. Well that would be a bit of info please do ask if you have questions and add your suggestions! It may take me a bit of time to respond, I'm giving workshops and exchanging cultures in Prague hackerspace Brmlab now https://www.brmlab.cz/project/food_hacking#bio-culture_exchange (got starter from Dan to make my own tempeh :-))) and I will be leaving for Korea on Saturday, I finally got working visa as a fermentation expert :-) Talk to you all soon, and below are few links which should help you to progress on kombucha and other ferments.
