Introduction¶
My work¶
Time Line¶
LoRa MESH¶
One of them can be found here LoRa MESH. I put it there as it seems more appropriate place to store it when I will search for it again.
So I am trying this out as I have some range issues with BlueTooth MESH.
Q&A¶
Plan a final project masterpiece that integrates the range of units covered, answering:¶
What will it do?¶
Pollution measurement inside my FabLab.
- Volatile organic compounds in the 3D Printer and Laser classrooms.
- Temperature measurement in classrooms and office spaces
- CO2 measurement
- Noise level measurement in classrooms (if I have time)
It will have different designs
- In classrooms it will have an educative design so we can explain what does what
- Offices will have a more artistic design to blend in
Live communication via a MESH.
Reason:
We are in a university so we need user accounts to connect to the WiFi.
So if the user leaves the project will brake as the account will be deactivate.
So I need a separate/independent network.
Who's done what beforehand?¶
SmartCitizen from Barcelona FabLab.
ESP32-C6 multi-sensor CO2, VOC, IMU...
Otherwise there is not much in the FabAc search:
What sources will you use?¶
- Different tutorials.
- Previous peoples work.
- ChatGPT.
What will you design?¶
Stations and code (more exactly putting together pieces of codes)
What materials and components will be used?¶
It depends on where the station will go.
Classrooms will be more with PMMA or MDF with 3D printed parts.
Office spaces depends on my mood and creativity.
Home made PCBs.
ESP32-S3 microcontroller and maybe Wio SX1262 module for LORA MESH
Different sensors
Where will come from?¶
FROM THE FABLAB !
Hi Luc 🙃
Note
Anyway.
So I asked Axel as he was the one who bought them but some of them was bought years ago so we are not sure where exactly. Our main supply sites are:
How much will they cost?¶

How will it be evaluated?¶
My evaluation will be
- Does it work
- Does the MESH works as intended.
- Is the MESH distance good
- Do I have sensor readings
- how effective it will be,
- data gathering
- and interpretation
- how easy will it be to deploy
- adding / removing new stations
- making it
Henk's Questions¶
How was fabacademy for you?¶
It was long and fun.
It has its ups and down. But mostly ups. And the stress of I need to write that down before the meeting
After the final project presentation I really could feel a weight difference. I felt way lighter.
20 weeks was really long without any brakes. At the end I started to have a hard time to do what needed to be done.
How was it to (only) have remote access to peers (dylan!) and me as instructor.¶
Being in remote I did not felt alienated / excluded. I always could write in mattermost and get a quick answer. I also had multiple people in my uni who I could contact in case of need of help.
The hardest part in being in remote is to figure out what you need to do & document for the group assignment. Most of the time I could follow the group assignment but was hard to for me to contribute to it.
True that when I was in present in waag for the group project it was better & funnier. I might have not needed the M&Ms if I wasn't in remote.
I also could yolo stuff without supervision.
I cannot say that it was a really good experience as the group life was missing but it was definitively not a bad experience. It was a unique experience. But it seemed to be a better experience than what happened last year in the fablab.
How did it work with you local (adhoc) instructors?¶
Both my instructors were great.
They helped me when I stuck.
Reassured me when I was lost.
Guided me when I was going the wrong path.
What did you expect before you started?¶
mmh
Answering this 6 month later is hard...
I expected some challenges. And some easier stuff. Discovering new things that I had no confidence or no knowledge to do.
But I underestimated the time length of FabAc and how much it takes on you.
How was the weekly flow?¶
A little too fast.
Like you are on the point to finish your weekly assignment that you are already in the next week.
Otherwise the pace of global in the afternoon than sleep on what we saw, think about what you will do and than next they your local intro was a good pace for me.
What weeks did you like and which you dislike?¶
There wasn't any week that I specifically disliked.
I do have some weeks that I like more than others thought.
Molding was one of my least favorite.
And Shy Xiao is one of my favorite.
What did it bring you?¶
Confidence for using the CNC.
I learned how to make a PCB.
Relearned to code.
And some more knowledge.
And of course, new friends.
What are you taking with you in future adventures?¶
PCB making.
Think out of the box. How to use what you have to do what you need to do. Prototyping on prototyping.
Think small first than make it bigger.
My friends.
Assignment Check¶
- Prepare drafts of your final project
- summary slide (presentation.png, 1920x1080)
- and video clip (presentation.mp4, 1080p HTML5, < ~minute, < ~25 MB),
- put them in your root directory,
- and check that they are linked in the final presentation schedule
- done
