First evening dedicated to design of a PWM (pulse wave modulation) power control module.
Every good hacker sooner or later will require a pulse wave modulated power source. To simplify the project, we will focus on the controller and modulator (MOSFET). The module can then be connected to a power supply of your choice. We are aiming to construct a controller that can handle from 3 to 80 V at frequencies from 10Hz to 50kHz and currents of 20A or more.
When: 12 jan 2015 19h-22h
Where: Foulab
Everyone who is interested by this project is welcome.
Software defined radio (SDR) has become easily accessible thanks to the availability of inexpensive “dongles” using the RTL2832U chip. However, after tuning in the local FM station, sometimes it is hard to go further. This meeting brings together people with an interest in SDR to share knowledge and collaborate on projects.If you have SDR equipment, please bring it for show and tell (hence the title). And of course, it doesn’t literally have to be an RTL dongle, other radio platforms such as FunCube, HackRF, SoftRock, etc would be great.
Anyone with an interest in software defined radio is welcome. No particular background is required.
Time: 13h-16h 29-Nov-2014 at Foulab
There will be a round table discussion (in French lang.) of the “Internet after Snowden” held at room Z-330 of Pavillon Claire-McNicoll at l’Université de Montréal on September 23, 2014 at 16:30. The session is free, but preregistration is required. Full information is here
The next meeting of Réseau Libre, “hackfest”, will be held at Foulab on Thursday, April 3 2014 from 7 to 9pm. On the agenda: a demo of the project Commotion-Babel by the Polytechnic students and other fun things. This meeting is open to everyone.

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”! OpenCV is an open source library for capturing and analyzing images and video. It is written in C/C++, and API’s are available in Python, Java and on Android and iOS.
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 (OpenCV),
- An introduction to computer vision algorithms (including image filtering, face detection, segmentation, tracking and stereo vision),
- Code walkthrough and demonstration of OpenCV examples that you can use as starting points 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. The workshop presentations will be in English, but we are more than happy to provide support and answer questions in French.
Time: Sunday, February 9, 1-5pm
No space left! However, if you would like to indicate your interest in us repeating the workshop please do at the email below.
Cost: 25$ (Cash, or make arrangements in advance at the following email)
RSVP to strawdog3 (at) gmail.com required. Space is limited.
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!
