Who I am

About me:

I am your host, Sylvain Bissonnette. I am French Canadian (Québécois) and live in Boucherville, QC.

My passion for electronics systems started when I was 8 years. My dad also worked in electronics and he's been my mentor.

What I like the most in electronic is working with MCU and developing embedded and Windows software for my systems.

Currently, I am working for Hydro-Québec (the Electric Company). I am part of a dynamic team working in research and development.

My main duties consist in designing and developing device drivers for various projects.

I love my work and have been doing it for more than 20 years.

My other activities are: Scuba diving, underwater photography, travel, wood working and of course, drinking beer!

Cheers,

Sylvain Bissonnette

Hi Friends

     English is not my native language,  I'm french speaking, so that's why there is a lot of gramatical error in my blog & code.  I will be please to correct those error if you point it to me.

    I also want to clarify, that all I give is on my blog, do not ask me for PCB or any other files or "Please help me" without doing anything before writing to me. I think I am generous please do not exaggerate.

History

Here is my PCB shop,  If you do just a little bit of electronics you need this. Home made PCB is a kind of an art.  You can archive without any problem track as small as 10 mils without any trace cut or short.  I've used MG Chemical products with great success. One thing to know is that there is a lots of possibility of problem due to many factor.

Bench Power Supply 0-25v @ 0-5amp

Author admin    Category Work Bench Tools     Tags , , ,

History

This project is like the one that all of you must have done in electronics.  I took the idea from Circuit Cellar. The original power supply provides an output of 2.5-15V at 500mA. This circuit will provide 0-25V at 0 to 5A. You will see there is a lot of modification to achieve this.

This is my second version of this power supply, the first one was made with mosfet who need a higher voltage on the gate I had to use a higher input voltage and because of this there was a lot of heat generated for nothing.  This version work with transistor and it's much more better.

AVR Code Debuger


History

    The fact is, 10 years ago this project could have been completed. It will be a useful tool to help you debug code. The challenge was to make a debugger that does not require any MCU resources to be used from the MCU, allowing the debugger to run integrated with the code being debugged.

Mood Light

History

    This project began when I was surfing the web looking for any cool electronic projects. I found the mood lamp made by Toon Beerten "http://tobe.nimio.info/led_mood_lamp.php". I was really impressed by the 3 watt RGB LED. I bought some of those on ebay and made some tests with an AVR with PWM to control each color intensity. At this point I found those LEDs very interesting and powerful, so then I needed a project.

Inductor & Capacitor Meter (LCMeter)


History

    Here is my new inductance & capacitance meter. I had took the analog oscillator part from a well know schematic found on the internet and adapt it for a AVR.  It's impressive to have a very accurate result with a so small circuit.  The way it's work is simple you chance a oscillator frequency with the part you want to find is value.

Scope Clock


History

One day my father asked me if I wanted his old Heatkit 10-10 oscilloscope. Quickly I said "No. What can I do with this old AC-only 500khz single trace scope?" A couple of weeks later I was surfing the net and I saw some guy who had made a clock with the CRT like my father's scope. I grabbed the phone to ask him if he still had the scope … and the answer was yes.

Train Modeling Digital Control (DCC)

History

    This is a common project with my father, building a train modeling. One more time it could be simple, but I had decided to challenge myself once again.  The train modeling had changed with years, now you can have more than one engines on the same track and each one could have a different speed, direction "watch out".  It's done by sending data on the track by reversing the voltage on the track with an exact timing protocol.

Function Generator

History

This project didn’t look complicated but it was. The MCU part is really simple: just some code for the Display, Keypad and DDS Communication.

A DDS is a chip that is driven by a hi-frequency oscillator. I used a 50 Mhz clock. Inside this IC there is a big divider that goes down to less than 1Hz. The resulting clock is passed to another counter which is connected to a Sine ROM table.  If you need a triangle wave, the counter is directly connected to the output.  For a square wave, the signal which drives the counter is redirected to the primary output.

Digital Room to Room Intercom

Author admin    Category All projects, Audio     Tags ,


History

This project was inspired by my girlfriend, who asked me to build an intercom for our house. There are many ways to build an intercom; an example is batteries in series with 2 telephones, a key switch and an amplifier. I felt this was far too simple. I decided to build an intercom with an MCU which digitalizes a voice and then sends it serially and then regenerates the analog signal.

History

I found this LCD make for cellular phone Nokia 3310 by browsing the web at www.jelu.se. There is many interesting things about this LCD: low price, easy to interface via SPI port, can support graphic and text and consume low current.  The only thing that I did is writing code who gives you friendly functions to support this LCD.  The last version of the library only send the bytes who had changed since the last update. It's considerably reduce the refresh time who can be very important in a batteries powered system.

OneWire Library

History

The OneWire protocol which in fact needs two wires (data and ground) is fantastic for many reasons: you can have a very long cable (250 feets), you can have multiples of devices on this cable and with a simple code you can poll those devices to get temperature, voltage, switch position, wind speed, etc.

MP3 Player

Author admin    Category All projects, Audio     Tags , , , , ,

History

I decided to do this project for several reasons: first I like music, second I have a huge collection of MP3, and third I wanted to be able to play them anytime in my living room.  I began the project with one major restriction, the printed circuit board of MP3 player MUST be single side in order to do it myself.  After 2 months of drawing, I realized this project was in fact ‘feasible’! One major characteristic of this player was the bi-directional remote control. I had to give several information, folders and songs on a small graphic LCD.

Propeller Clock

Author admin    Category All projects, Gadjet     Tags ,

History

I got this idea by browsing the web. I found by hazard  Mr. Bob Blick's page who make the first propeller clock.  I began to check how can I build one myself.  Base on AVR AT90S2313 I saw rapidly that my MCU must be clocked very fast to make all the calculations needed to light the leds at the right place.  The speed is at 16Mhz,  4 times faster than Atmel's specifications. It's working without any problems.
