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. Project initial Sketch

<figcaption>Project initial Sketch</figcaption>

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?

Research


To understand how incubators work and the required manipulations I have searched for and read through the following:

First spiral

functionalities :

  • Confirm a Heating element design choice
  • Regulate the heating
  • Implemented egg plat tilting function mechanism
  • Value sending online

What did you design?

I have Designed:

  • the 3D printed parts for the tilting mechanism
  • Tray,
  • Tray holder;
  • Stepper Mount;
  • Mechanism Shaft;
  • Stepper Spacer,
  • The frame
  • The PCB board
  • The Logo

What processes were used?:

  • 2D/3D design
  • CNC Milling
  • Electronic Design
  • Electronic Production
  • 3D Printing
  • Solder (Reflow and Soldering iron)
  • Embedded programming
  • Network and communication

Design and fabrication results

3D Design and printing

This part is the Shaft for the tilting Mechanism. It goes on the stepper axis and host the fishing line that used for the tilting mechanism.

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.
