Logbook

The first week was a presentation week. Teachers and students introduced themsleves. Teams were made. We also had the opportunity the strenghten the links between each members thanks to the “Team Building Activities”. We had a small meeting to choose which were our three favorite options. This was our list: 1) Disaster shelter 2) Bicycle Probe 3) Crosswalk Safety.

We finally get our second option which is Bicycle Probe.

We started our research about the possibility to integrate different sensors in the bike, to increase the quantity of data available for the bike user and the community. After the first meeting with the professors, we had a new point of view which is way less ambitious : our two main missions for the bicycle probe is to integrate an air quality sensor and to ensure the safety of the rider. We then looked for bike sensors which already exist in the market.

We made our Gantt Chart and tried to think of all the possible processes we need to do, so have a complete product at the end of the semester. We discussed about the different ways to power our product. Should we produce our own energy, using generators or solar panels? Or should we just use batteries? Discussed about what kinda sensors and parts we need and how expensive they are.

We started to think how complete product should look like and started to make sketches of complete product. We also made cardboard-model and small video from our product.

Started to make black box diagram.

1. Presentation
2. Modus operandi
3. Project proposals
4. Electronic logbook (Wiki)

A general meeting to get to know the 16 subjects we can choose.

1. Get new ideas
2. Ask about wind propeller

We have to put the focus on air quality sensors and on the safety of the cyclist. Light indicators should be a good solution to give information to road users. Air quality information will be updated to a cloud so that the community could be aware about the most polluted places.

1. Discuss about Gantt Chart
2. Present our research about State of Art
3. Present the big idea about the whole system, thanks to our work on design thinking
4. Have information about how to link our sources

During the meeting with the teachers, we clarified which conditions are gonna be assessed by the bike : safety indicator lights which can react with acceleration and air quality sensors.

1. Is it worth it putting a (bluetooth?) back light connected to the bike ?
2. How to link the 2 side lights?
3. Another option would be to add laser lights instead of side lights
4. Will the dynamo be powerful enough in powering the battery?
5. Waterproof air pollution sensors doesn't exist : need to find a solution

We reconsidered the solution of the wireless backlight or a plug/unplug cable. We need to be careful with the calibration of the sensors. A comparison table is needed to assess the better solutions for the sensors and the dynamo.

1. Creation of an application on Android to show the user the air quality and temperature
2. Lights turn on automatically with the environment light intensity

1. Enquire about lead acid battery use
2. Enquire about connection of dynamo to battery

1. Is sensor CCS811 good?
2. —-
3. 3D Model
4. Connection between dynamo and device

1. 3D model video
2. Backlight
3. Materials list - sourcing
4.

1. How functionnalities and tests look like ?
2. How about discussion ?
3. Where to look up for the price of raw materials?
4. Reasons we are not doing the back light
