Welcome to Martin's Awesome Project page. Enter my lair!
This is GitHub page page to describe the various projects done in that repo.
Pet Feeder Pet Project (PFPP)
(Also formaly known as Beast Feed'Her or BFH for short.)
PFPP is the 1st project done in MAP. PFPP is a smart, connected pet feeder for my pet cat.
The reasons why I wanted to do this project (beside the obvious utility to feed my cat while I'm out!) are:
- Learn about QP event-driven state-machine framework.
- Learn about ARM-Cortex M3 MCU.
- Learn about IoT and mobile applications.
The very first version was going to be a "smart" device, e.g. being able to program it and operating autonomously afterward. this version never saw the daylight as I went straight to the "connected" version of it soon after start.
As said above, the next (and current) iteration is to make it a "connected" device. This means its configuration and operation can be accessed via local network (LAN and potentially WLAN), mobile devices over BlueTooth, and such.
Eventually, I aim at making it an IoT device, where its overall configuration/operation can be done through the Cloud.

High Power Rocket Flight Computer
Achievement unlocked!
Mid-October 2019, I got my CAR level-1 High Power Rocket (HPR) Certification flying my MadCow Torrent rocket (affectionally called Cloud Buster, thanks to my friend Louis) at the October Sky launch event of the CQF club (http://www.clubqf.ca/index.html). The whole thing required passing an exam (with a passing grade of 100% on Transport Canada section), successful flight AND recovery, all of that entirely witnessed/supervised, doubled-checked and signed. No rubber stamping...
Now as much as propulsion and aerodynamics are fun, my thing is really about avionics and flight computers: I've wanted to build my own for a long time. So this project is about building avionics electronics and firmware for putting in my HPR rocket models. some of the things I want it to be able to achieve are:
- Determine apogee and trigger pyros events for chute deployment in single- or dual-deployment flights.
- Logging of events and various flight data like: acceleration, 3-axis position, time of flight, etc.
- Transmit in-flight data to ground through a radio link.
- Configure the flight parameter through mobile device while on the lauching pad.
- Broadcast landing position over GSM or other means.
- ... and more I can't think of right now.
Phases
In order to get there, here's a rough plan of various phases to achieve:
- Get HPR certification level 2 ('I' motor): optional, but can fly more powerful rockets!!!
- Build electronics & FW version 1: fly in recording mode only.
- This is a mean to see if main events can be properly sampled and logged for further analysis.
- Update FW to perform deployment of chute in single-deployment flight.
- Still use the motor deployment as a backup mean.
- Update FW to support dual-deployment flights.
- Add other bells and whistles.
To be continued...
