Foulab Double Header: Intro to OpenCV / Intro to WebGL
by [strawdog] @ 2013-10-10 00:00:00 -0400 EDT


Nov 2 and 3 Postponed, Foulab will present two workshops. On Saturday, learn to bring visual interaction to your projects with Introduction to computer vision with OpenCV, and on Sunday, step up to modern graphics in your web applications with Introduction to WebGL. Each workshop will run from 13:00h to 17:00h. Workshop attendance is $30 each, or $50 to attend both workshops. Each workshop is limited to 20 places, so get ‘em while they’re hot.

Tickets are for sale on eventbrite Each event alone is 30$, or 50$ to attend both.

The workshop presentations will be in English, but we are more than happy to provide support and answer questions in French.


Do you want to make your computer react to light, movement and gestures? Do you want to capture and process images and video as part of your project? Do you wonder: whats wrong with these lazy AI programmers, why can’t my computer recognize me yet? Get answers to all these questions and more at the Foulab Workshop “Introduction to computer vision with OpenCV”!

The workshop is aimed at people with some programming knowledge, but not necessarily any computer vision knowledge. We will cover:

  • how to install and set up the Open Computer Vision toolkit,
  • an introduction to computer vision algorithms,
  • a couple interactive OpenCV demonstrations that you can use as a starting point for your own projects.

The primary programming language for the workshop will be Python. The workshop has been updated from previous workshops to cover OpenCV 2.4.6, and the latest version of OpenCV’s python interface.

Time: Saturday, November 2, 1-5pm Postponed
Required materials: laptop, webcam

While this workshop will be limited in scope to OpenCV itself, people are encouraged to stay after the workshop and discuss more advanced topics, such as the interfacing of openCV with other libraries and languages. If you have projects in mind or in progress, please do stick around and chat with us!


Long gone are the days of simple text tickers and epileptic shock inducing blink tags.These days we see javascript as a fast growing multimedia oriented language, and the jump to 3D is now at the cutting edge of competing with your native desktop application with WebGL.

In collaboration with Montreal’s very own demoparty, RECURSION, and it’s hackerspace, Foulab, we are happy to present an introduction to the modern OpenGL 3D processing pipeline through OpenGL.

Building off certain image processing concepts presented in the OpenCV workshop, we will give you an introduction to the following concepts so that you may start programming your own 3D demoes.

We will go over a number of small things specific to basic demo making including: setting up the rendering pipeline, in addition to explaining its internals. Simple examples of procedural rendering. As well as an overview of how this can go on to be applied to OpenGL in general.

Time: Sunday, November 3rd, 1-5pm
Required materials: laptop, chrome

Please be advised that a working knowledge of basic linear algebra will be required, in addition to that of programming.

Gapzap recently scored some righteous looking lcd panels. It would be cool to include them as part of an Arduino workshop. However, we first have to figure out how they work. Time permitting, may also work on a few other Arduino related items, e.g. bootloader flashing. If you have Arduino projects, drop on down.

Cost: Free, although pass-the-hat style donations to support the lab are encouraged.

On Work In Progress Night a foulaber brings a work in progress to the lab and works on it for a few hours. Anyone interested can drop in to check it out and discuss the project, receive or give advice, or bring a similar project and work on it. There is no promise that anything will actually work, but it should be fun!!!

Work In Progress Night: Etch a sketch drawing machine.
by [strawdog] @ 2013-09-25 00:00:00 -0400 EDT

This is the first of what may become a series. On Work In Progress Night a foulaber will bring a work in progress to the lab and work on it for a few hours. Anyone interested can drop in to check it out and discuss the project, receive or give advice, or bring a similar project and work on it. There is no promise that anything will actually work, but it should be fun!!!

While the idea of putting a couple steppers on an etch a sketch to produce etch a sketch drawings seems straightforward, there are actually a number of tricky points. There is quite a bit of mechanical backlash in the sketch, meaning that the order in which you draw lines makes a lot of difference. The image processing required to generate a scene which can be drawn in a single line from a picture is also interesting.

Some previous work here

Cost: Free, although pass-the-hat style donations to support the lab are encouraged.

Announcing Foulab's 1st Junk Independence Day!
by [strawdog] @ 2013-09-13 00:00:00 -0400 EDT

Do you have any old electronic junk you want to get rid of? Do you like sorting through piles of old junk for cool stuff? Then you should come to Foulab’s Junk Independence Day on Saturday, October 5, 2013, from noon to 5 PM. Drop off any and all electronics you don’t want and/or take some cool stuff. You don’t need to leave junk to take junk! Junk is free for all!

On Tuesday, October 8 at 4 PM, any leftover junk will be taken to the Ecocentre for recycling.

BuildSomething: A Hardware Hackathon
by [legionlabs] @ 2013-08-16 00:00:00 -0400 EDT

It’s a “hackathon” where you get to build something awesome in one day. Your project will get reviewed by a panel of judges and there will be prizes from sponsors in several categories.

There is no category limit as long as its a hardware build. You can come as a team or try to join a team on the day of the event. You can and should bring all necessary parts and extras which are prepared ahead of time but the project must be built on the day of the hackathon.

The following tools will be available for you to use (with assistance of a pro if necessary):

3d Printers
CNC Machine
Soldering Station
Oscilloscope, multimeters, microscope  

True hackers will just come with a box of electro junk and build an awesome prototype during the day. More info at Build Something

When: Saturday August 10th, 2013 9:00 to 21:00+

Where: Suite 33B, 999 du Collège, Montreal, Quebec, Canada, H4C 2S3

9am - 10am Registration and Team Formation
10am - 7pm Hacking and Building
7pm - 9pm Presentations & Dinner
9pm - 11pm After Party
