Week 16: System Integration

Assignment of the week:

• Design and document the system integration for your final project.

So, for the past few weeks, I have been working on my final project and I was able to make some good progress with Sir Rico and my local instructor Sir Anith helping me.

Enclosure

Pot Design (Fusion 360)

For the pot design first I referred to Mr. Pablo Pastor and designed a similar pot. Now, I want to modify this pot with my own creativity!!

Personalized Design

Hey there after 10 days!! So today, I am planning on modifying my enclosure and my idea is to integrate a shark mouth to the flower pot.

I got this idea from google, I call it shark pot🐠

I had some trouble making the shark but I managed it using the form tool in Fusion 360.

Here comes my first draft enclosure!!

I 3D printed my first draft!! Thank you Damzang for helping me print them!😘

Welcome to the Xiao World! (May 19)

Today, I decided to switch my MCU for my final project from ATtiny1614 to XIAO-ESP-C3 after hearing a lots of compliments and recommendations for it from many fab members especially Sir Rico and he is coming to Bhutan today!!

Here I am now and here is the pinout of the ESP board.

This is my schematic for the board.

Here is the PCB of the board.

And here is my board and it is approximately 60mm by 40mm! Better take that into consideration for my enclosure.

Redesign (May 21)

🤔 Hmm...So I have to redesign my enclosure as there are some issues and I think it is also a bit wiggly.

These are the issues with my old design.

• The body from where water is filled holds the electronic components so, there are chances that the water might come in contact with the electronics.
• The electronic components needs a larger area to fit in for proper integration.
• I switched to capacitive moisture sensor as it is more durable and works more efficiently. So, I have to redesign the slot for it.
• The water tube was designed below the moisture sensor which was a stupid idea so I designed it in a way that it comes out of the shark's mouth.

These are some notes from Sir Rico and it really guided me with the designing!! 😊

Here are the changes I made to my enclosure:

• Made one side of my pot flat to integrate my boards and relay module.
• Attached a hollow mouth to the tank to fill water in it.
• Created a hollow space in one side of the shark's mouth to fit the water tube and dispense the water from there.
