Ahoj, jak tak koukam, mam asi vestecky dar. Pred par tydny jsem z nahleho popudu zacal psat povidku, kde mj. vystupuje i obraz neceho jako brmlabu, opusteneho az na jednoho cloveka, se socroomem zabydlenym plysovymi medvidky, kteri delaji, ze vedou rozhovor, diky nekolika kopiim muaddiba (aby se ten jediny clovek, ktery zbyl, necitil uplne sam). Jen jsem to umistil do budoucnosti zhruba za 80 let... (a samozrejme, ten posledni clovek nejsem ja - me alter ego je v te dobe mrtve). J. D.

Ochrana soukromi v brmlabu
by brm zlodej 24 Nov '13

24 Nov '13

Nedavne udalosti dovedly vedeni brmlabu k rozhodnuti nainstalovat smirovaci kamery v brmlabu. Rozhodl jsem se tedy, ze pomohu vsem kdo chteji do brmlabu prijit a zachovat si svou anonymitu. Koupil jsem celovou svitilnu a pridal jsem do ni infra LED svitive diody. Takto hacknuta svitilna zabrani snimani tveho obliceje. Levne smirovaci kamery, ktere jsou v brmlabu nainstalovane nefiltruji infracervene svetlo a misto snimani tveho obliceje budou oslneny svetlem ze svitilny. Svitilnu lze take pouzit proti snimani klavesnice behem psani hesla a tajnych zprav. Celni pas drzici svitilnu lze zkratit a pripevnit na ud v pripade potreby se vymocit. Hacknutou svitilnu lze odeme zakoupit za 200,- CZK nebo 0.01202 BTC. Paypal: http://snipurl.com/brmzlodej Bitcoin: 1BRMLAB7nryYgFGrG8x9SYaokb8r2ZwAsX Kradez neni dobre brat na lehkou vahu, nekdo vas muze chytit. Lovu zdar, zlodej

Fw: [sf-lug] fascinating story: How Munich rejected Steve Ballmer and kicked Microsoft out of the city

Zatracená kasička

BrmBrm, situace ohledně ztracené kasičky mě velmi tíží. Hlavně v tom směru že podobné "náhody" jsou nebezpečné spíše než z hlediska financí tak z hlediska rozrušování komunity jako takové.Zaplať pánbůh jsem se krátce po řešení neztracené Weller mikro páječky rozhodl "nelegálně a bez souhlasu" pokrýt cástečně prostor BrmLabu dvojicí kamer a to i s vědomím perzekucí ze strany rady a některých členů za monitoring bez souhlasu. Bohužel je to ale obrovské množství záznamu k prostudování. Dnes jsem si stáhl data a sbírám psychických sil abych je prošel. Pokud si někdo čirou shodou náhod kasičku vypůjčil a zapomněl na to tak prosím o její navrácení do příštího meetup-u.Pokud se tak nestane, závěr vyplývající ze záznamu zveřejním a oficiálně požádám radu aby s tímto materiálem zahájila oficiální kroky.

Vstupne karty (brmlab + bubenska)
by niekt0 21 Nov '13

21 Nov '13

Zdar, od axa dorazila zasielka vstupnych kariet s logom brmlabu. Graficky sa podla mna viac nez podarili, viz obrazok. Karty maju naraz aj magneticky pruzok aj mifare chip. To znamena ze ich mozete pouzivat ako vstup do budovy bubenskej aj do brmlabu. Cena za kartu je 50czk. Prvych par kariet sa uz rozdalo, kto chce dalsie tak idelane odchytit niekoho z rady, kupit si kartu, nechat si nahrat magneticky kod, pridat mifare ID do brmdooru, a hotovo:) V utorok bude idealna prilezitost, mozno sa vam to podari aj skor. n.

Optika v brmlabe
by niekt0 21 Nov '13

21 Nov '13

Zdar, dnes v noci sme spolu s Harviem natiahli do brmlabu opticke vlakno prepojene na centralne switche v Bubenske. (za co mu patri velka vdaka) Zajtra by sa malo vlakno ozivit, ak by niekto bol doobeda v labe, bolo by to idealne. (!!) Zaroven by som vas poprosil o zvysenu opatrnost pri manipulacii s rackom, nakolko optika tam nie je zavedena kompletne blbuvzdorne. (!!) V praxi to znamena (bude znamenat) zlepsienie konektivity brmlabu v ramci budovy z pochybne fungujuceho 100mbitu (na 300+ metrovom utpcku:) na bezproblemovy gigabit, v buducnosti v pripade potreby viac. Samotna konektivita budovy Bubenskej sa zatial nemeni, ale spoje.net rozmyslaju o dotiahnuti optiky, tak mozno casom. Ak by ste niekto mal kontakty na ludi ktory vedia ktore vsetky opticke vlakna su vedene pod budovou, pripadne komu patria, kludne sa ozvite sukromne do posty. A jedneho dna bude v brmalbe gigabit na 2 hopy do nixu! :) Este raz kudoz Harviemu a spojom. n.

pořízení záznamu beru jako nutné zlo. protože události které se dějí by měli jen za následek totální rozvrácení brmlabu a jeho konec. tohle se dříve nedělo takže se nemuseli dít takové věci jako je narušení soukromí... a tohle je jedna zmála věcí jak se tomu dá zabránit - eleminovat lidi kteří svým konáním a činy rozvrací náš spolek zevnitř. nelíbí se mi to... ale chápu to a vím že tohle zlo (kamery) bylo nutné aby bylo možné eleminovat prvek rozvracející všechno co máme rádi.. ano kamenujte mne.. prostý kalkul - nebýt kamer způsobené škody by dlohodobě mohli být mnohem vyšší (nemluvím o financích či hmotných věcech). tlapka zaznam at si projde rada spolecne

Ni-Cd 18VDC charger
by Mario Lombardo 20 Nov '13

20 Nov '13

Hi everyone. I have a battery and base station for an 18VDC cordless drill from Tesco. The old transformer/charger died like most of the functional toxic waste from China. I want to replace it, but I don't recall the specifications. I believe the base station is completely dumb with no electronics, only like a connector and some LEDs. Knowing this, does anybody know what specifications of the power supply should be to properly charge the battery? I know it may need conditioning, but I can do that myself. Regards, /mario

ma ceska republika specielni dan na import uloznych zarizeni (tak jako nemecko)?
by Frantisek Apfelbeck 20 Nov '13

20 Nov '13

Zdravim ve spolek, Mam prosbu. Kamarad z Nemecka me zada zda mu muzu sdelit ma-li Ceska Republika nejakou specielni dan na dovoz/import USB sticks (Nemecko ma, plati z toho jakousi GEMA - velke hudebni firmy si narokuji dan z jakehokoliv importovaneho ulozneho zarizeni - doufam, ze jsem to pochopil, zni mi to dost zvlastne). Ja nemam zdani, tak pripojuji dany email a zadam o radu. Moc dik, Frantisek PS Verili by jste, ze v Irsku je napriklad ilegalni sbirat třezalku za ucelem suseni a uzivani? To si pro zmenu prosadily velke farmateuticke spolecnosti ... I want to import 100 USB sticks with write protection switch from China (for use with Tails), but I don't want to ship them to Germany because Germany has additional fees on USB sticks (GEMA, paying off the big music business for any storage device). Do you know if you have similar import fees in Czech Republic? I know there will be some taxes, but from what I hear most other EU countries don't have this additional GEMA fee (~2 Euro per stick).

elektronicky oscilloscope - rady pro dobrou koupi?
by Frantisek Apfelbeck 20 Nov '13

20 Nov '13

Zdravim ve spolek, Nekteri z vas si asi pamatuji, ze ccca pred pul rokem jsem daval dohromady proposal ohledne vybaveni fermentacni stanice a cafe/baru, plus pro tuto diskuzi dulezite vybudovani "elektronicke laboratore" z penez mistni vlady, kopie zde https://docs.google.com/spreadsheet/ccc?key=0AoI1FSp-qkEWdERyYzQ1UzZ1UXBMen… Penize nam byli preklepnuty (cca $20 000) a ted je nutno poridit vybaveni a to dosti zahy, na elektronickou labku bude verim cca pres $1000, pod $1500. Jedna z veci, ktera by tam asi mela byt (dle nazoru odborniku) je oscilloscope, nevim ale ktery by byl vhodny, starsi CRO's nebo novejsi DSO's? Na wiki jsem nasel nasledujici text: CROs were later largely superseded by digital storage oscilloscopes (DSOs) with thin panel displays, fast analog-to-digital converters and digital signal processors. DSOs without integrated displays (sometimes known as digitisers) are available at lower cost and use a general-purpose digital computer to process and display waveforms. Je nutno upozornit, ze z budgetu nelze zakoupit veci ze zahranici, pouze domaci produkce a to jen nejaka (ano pekny opruz), plus je mozno porizovat pouze nove vybaveni, zadny second hand. Nuze doporuceni? Pokud vidite neco co by v laborce byt melo a chybi dejte mi prosim vedet, jeji hlavni funkci je podpora budovani vybaveni usnadnujiciho food&beverage hacking, takze susaky, inkubatory, low temperature cooking water baths etc. Moc dik za rady, S pozdravem z Jeju, Frantisek Algoldor Apfelbeck PS Apropo je toho nutno hodne na leptani vlastnich PCB desek? Vim, ze to v Brmlabu delate ja nasel napriklad toto info, pro me zrejme etching http://www.build-electronic-circuits.com/diy-pcb/ biotechnologist&kvasir and hacker http://www.frantisekapfelbeck.org "There is no way to peace, peace is the way."
