About Garoa Hacker Clube

Garoa Hacker Clube is an open collaborative space that provides the needed infrastructure to technology enthusiasts to develop projects in various areas like security, IT, hardware hacking/development, electronics, robotics, aero/space modelism, software development, biology, anthropology, music, arts and whatever the creativity permit.

For about a year and a half we are in a permanent and constant evolution of the space, attended by anyone who desires to participate in activities or develop projects. We provide access to a variety of equipment, tools and materials for project development, such as a 3D Printer, Arduino kits, sorted electronic components, woodwork basic tools, welding stations, electronic instrumentation (oscilloscope, function generator, multimeter and power supply), some spare computer parts and an extensive library.


Garoa Hacker Clube, the first Brazilian hackerspace, located in the city of São Paulo, was founded by the mobilization of a group of enthusiasts with the idea of forming a hackerspace in Brazil. The group was initially mobilized via web social networks ( and, later on, met in person at universities, congresses and other meetings.

After about a year of online discussions and planning, the group started to meet in regular basis at University of São Paulo (USP) and, less than two months later, and still without an official name, moved to what today is half of its current physical space: a 12 square-meters basement in the House of Digital Culture (Casa da Cultura Digital). Gradually the group started to get its identity better defined, which culminated in the choice of a name to represent the local culture, our goals and our identity.

With the start of regular activities, such as Arduino Night, the Turing Club and the Hackdays, the space got established as a meeting point for hackers and such, so that one can say "let's go to Garoa! " with the certainty of finding a project being developed, a lecture being presented or simply to have some fun.

In order to give legal and financial support to our activities, on February 20th, 2011 (in UTC 1298244863) Garoa Hacker Clube was established as a legal entity of private non-profit social, cultural, educational, technical recreational, scientific and without a religious or political direction, which is intended to provide a community infrastructure open to those who wish to conduct individual or collaborative projects, sharing knowledge and socializing.

During 2011, more and more people started attending Garoa and got in contact with the hacker philosophy and shared knowledge through projects and activities - in addition to the original activities and projects, members and att endees proposed in 2011 and carried out new activities such as the Pinball Night , the Relearning how to draw workshops and Arduino Clueless (Arduino Sem Noção) as well as occasional events such as Electronics with care(Eletronica com carinho) , the Conference the Other Side (CoOL) and Garoa Hacker Camp, or sudden and improvised events such as coding-dojo and Lock-picking workshops.

Given the success and strong adherence to these activities - not to mention the various personal projects developed by our attendees - the growing community of Garoa have suffered from severe room limitations. Occasions in which the hackerspace is attended by a dozen people without any prior notice are no longer rare. Although the current space limitations have not limited our ability to develop new activities and projects, we have been facing difficulties to reach a larger audience in such events to perform activities which involve the existing public request.

Thus, we wish to open ourselves to the aid of external entities that share our ideals and respect to reach the physical expansion that we need.

The Social Impact

Result of the initiative of 16 founding members, today we have 25 regular members, about a hundred sporadic attendees and a discussion list with about 600 participants.

Inserted in the global context of hackerspaces, Garoa has conducted dozens of activities involving hacker culture and digital technology, such as workshops and lectures on programming, electronics, information security, hacktivism, design and fine arts.

These activities are performed mostly by Brazilian colleagues, but also included the presence of hackerspaces members and groups of other countries like USA, Spain (Catalonia), Chile, Portugal and Germany, attracting hundreds of interested in the hacker culture for their events and its cause.

In addition, its members have already made 17 hackerspaces cultural exchanges in the world during the pre and post-foundation phases, having also collaborated in the creation of HHSPP (hackerspace ping protocol) and participated of the Great_Global_Hackerspace_Challenge.

Casted as one of 26 Brazilian security and cyber defense research centers by the government report Strategic Challenges for Cyber ​​Security and Defence, which aims to guide the development of public policies in the area of ​​cyber security, Garoa has acted as a think tank culture hacker.

In 2011 Garoa contributed with the proposed policy Incentives System for Shared and Collaborative Science Production Capillarization, Technology and Security in the Information Society. Of interest to the community, this contribution has served as core supporting the formation of new hackerspaces, having already been involved with the foundation of two hackerspaces in the state of São Paulo and actively collaborating with the formation of nine other similar spaces in Brazil, within the possibilities of association, usually relying more on the passion and commitment of its members than with the resources available for involvement in these activities.

Garoa Hacker Clube Activities - Numbers in 2011 and goals to 2012

"Arduino Madness" Workshops

Arduino 100 Nocao abertura.jpg

Attendance in 2011: 100 participants (10 events organized)

Public Forecast to 2012: 500 to 800 participants (not considering structure changes)

Maximum Capacity per event: 15 participants

Event type: Free workshop

The "Arduino Madness" workshops began on August 1st, 2011 and took place every Saturday from 10am to 1pm at Garoa’s headquarter and also sometimes in external places. The workshop was also presented at the Federal Institute of Technological Education from South of Minas Gerais. In 2012 the workshop was presented with huge success at the Campus Party event in São Paulo.

So far the workshop was attended by about 100 people (considering an average of 10 participants per event) who have learned what is a microcontroller and its relation with the Arduino system through manual setting of a led in a breadboard system.

The main goal of this workshop is to bring more visitors and members to Garoa Hacker Clube, thereby providing a basic level of knowledge for their integration activities of the club and the free software and open hardware movements that are part of the hacker philosophy and attitude.

Teaching materials we provide as textbook with simple content and easy access in the form of a comic book. As practical material (the electronic elements) are provided for each student to use, the workshop runs at no cost. At the end of the workshop the participant understands that its possible to set up a system with low cost microcontrollers and understands that there is no dependency from ready, imported or manufactured systems to release your creativity as a creator.

For the year 2012 we intend to serve around 500 people in Garoa Hacker Clube headquarter and expand the activities to other places, reaching even more people. For instance, the workshop has being adapted to meet the child audience, aiming to give an opportunity for integration between parents and children in a creative space and freedom.

With the increase in the space provided by the partnership with Mozilla Foundation, we forecast a growth of 100% in the number of people served in 2012.

Conferência o Outro Lado (Co0L) (English: The Other Side Conference) is a mini-conference on information security, organized by Garoa Hacker Clube as a way to promote information exchange, integration among participants and the hacker culture. Co0L was inspired on "Security B-Sides" held in various countries, but adapted to the Brazilian reality. The conferences called "Security BSides" are usually small conferences that take place in parallel to some big event, but more informal and entrance is free.

Taking advantage of a gap between two relevant information security conferences take place in the São Paulo Area, Co0L provides attendees with a a whole day dedicated to activities that promote information security through the integration among hacker culture enthusiasts and national security community members.

"Co0L" was first held on 05/15/2011, lasting about 9 hours, and serving as a “B-Side” to two traditional Brazilian security events, namely Working Group on Network Security (GTS) and You Shot The Sheriff (YSTS). The second edition was held on 12/04/2011 as “B-Side” to GTS and lasted about 14 hours. The next edition is being held on 05/06/2012, and registration booked out 21 hours after the initial annoucement.

Attendance in 2011: 15 attendees

Attendance forecast for 2012: 50 attendees

Event type: Camping conference, with outdoor lectures, workshops, debates, artistic performances and leisure.

Garoa Hacker Camp is inspired by events like Chaos Communication Camp, Hacking at Random and others.

Garoa Hacker Camp is an event out of the comfort zone of our basements and promotes fellowship among hackers, supporters, members and attendees of Garoa and other Brazilian hackerspaces (active or under planning).

Above all, it's a good opportunity to exchange ideas, learn, teach and, especially, hack outdoors.

The beta run of Garoa Hacker Camp was held over a weekend between November 18th and 20th 2011 in a small farm near Ribeirão Preto (~360km away from the state capital), and allowed attendees to experience a new event format. Several workshops and debates were held despite the limited internet collection, which enabled attendees to focus on hands-on activities and socializing.

Infrastructure costs

The following table lists the monthly costs of infrastructure designed in accordance with the goals of Garoa Hacker Clube for the next two years.

Item Description and Explanations Monthly Cost
The HeadQuarters The most important prerequisite for the emergence of a

hackerspace, and the hackers themselves. The place must be spacious, easily accessible, safe and adaptable. In this sense, we searched for locations near subway stations in central São Paulo with approximately 200m², with an area comprising groups of 40 people for lectures, workshops and events, with room for heavy machinery and laboratories and environments to allow meetings and many collectives.

After a search of available properties in town, we conclude that the best option would be sheds. There are good options, but given the volatility of this market, we can not choose in advance. So we've listed some examples that guide and our intention.

The estimate costs includes taxes, rent and other fiduciary expenses.

R$ 5,000

(~USD 2,700)

Water and electricity R$ 350

(~USD 185)

Internet There are few companies in São Paulo that provide Internet

access. As none of them cover the hole city, the final choice will depend on the location of the HQ. Here we have a coparison of some Internet Providers costs and speeds:

NET Virtua 20Mb R$ 179,90
Speedy 8Mb R$ 89,90
GVT 35Mb R$ 149,90
Ajato 40Mb R$ 98,00
R$ 150

(~USD 80)

Maintenance Given the size of the property, the expenses on cleaning and

minor repairs can not be neglected. We will need to hire a person once a week will help us keep Garoa clean and functional.

R$ 500

(~USD 270)

Secretary/Intern It is our intention that Garoa stays open as much as

possible and people who arrives to be received, welcomed and oriented.

Moreover, since the principle is our intention that the hacker culture is disclosed, informed and respected and that hacking is not seen as a criminal occupation or merely playful. In this context, when we see the importance of creating a position for a "professional hacker" (an intern).

R$ 1,000

(~USD 540)

Total Infrastructure Cost R$ 7,000

(~USD 3,775)
