Hero Shot¶
3D design live Fusion 360¶
What does it do?¶
My project : EyBroody - Egg incubator for hatchery¶
My project is to make an Arduino controlled and possibly connected egg incubator. Egg incubators are machines that create the perfect conditions ( temperature, moisture, positioning) for an egg to incubate and hatch successfully. It’s designed to regulate incubation temperature and humidity at perfect levels there for playing the role of a broody hen.
It is used by farmers and used by farm providers to produce and sell chicks to farmers.
The functionalities I taught of :¶
Make an incubator that :
- Can set and efficiently control the temperature inside the incubator
- Can set and efficiently control the moisture inside the incubator when required ()
- Ensure energy efficiency through proper insulation and energy use.
- Have a programable cycle depending on the type of egg.
- is connected for live monitoring
- Log data for later analysis and use.
Who’s done what beforehand?¶
- Lucio Pentagna tried something similar on his fabAcademy Journey.
- ESP32 Web Server for Live date plotting Based on Random Nerd Tutorials
- NTP client to get date and time on Random Nerd Tutorials
- Use of telegram bot sensor monitoring
- Heater PCB trace Calculation
- Tilting Mechanism inspired By Quentin Bolsee’s beehive-axes
Research¶
To understand how incubators work and the required manipulations I have searched for and read through the following:
- Agromisa Agrodok No 34 PDF this gives me most of the needed information
- A professional Agricultural equipment seller website
- DIY Build on Youtube for a same similar project

Link to weeks that contributed to the finale project:¶
- on ‘Week 02 - Computer Aided design’: I have made My logo Design to be cutted wih the vinyl cutter as Sticker. and I have design the Parametric Egg plate and started the design of my Frame
- On ‘Week 04 - Embedded programming’: I have confirmed the use of telegram bot as a way to interact with my incubator.
- On Week 07 - Computer controlled machining’: I have Cutted a design of my frame with the CNC and got Joinery feedback From professor Neil
- On Week ‘08 - Electronics production’: I have tried the PCB heater.
- On Week ‘09 - output devices’: I have Milled stepper output and a Mosfet PWM board to test their use on my project.
- On ‘Week 14 - Interface and application programming’: I have confirmed the live data plotting with the ESP server
- On ‘Week 14 - Interface and application programming’: I have confirmed the live data plotting with the ESP server
- On ‘Week16 - Applications and Implications’: I have checked my plans for the project and improved the BOM
- On ‘Week 17 - Invention, Intellectual Property and Business Models’: I have decided the license for my project

What questions were answered?¶
The goals for our first spiral were all reached.
- Confirm a Heating element design choice
- Regulate the heating
- Implemented egg plat tilting function mechanism
- Value sending the web server
What worked? What didn’t?¶
- While milling my board a have mirror it so the trough hole components sit o top of the non coper surface but flipped it on the wrong Axis and had to re-o it. Appart of that the rest was okay.
- We have to optimize our PWM Mosfet control for the heating system and redesign a better PCB heater.
- From feedback From my Instructor and Professor Neil I have to optimize my PCB Heater Tracks width
How was it evaluated?¶
The evaluation were made on the following criteria:
- The heating system is working
- the heating is being regulated
- The egg plate is tilting
- Value are being plot on the web server
What are the implications ?¶
To make this product marketable here in Africa we need to optimize it final cost and material use that make it look of quality but at an affordable price. but the FacAcademy achievement are already a very good start to build on.
