Project development¶
What tasks have been completed?¶
For our first Spiral we have managed to: * Control the temperature inside the incubator * Make a working tilting Mechanism * The incubator is connected for live monitoring
Plate Tilting Mechanism
3D print¶
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.
Bellow the egg Holders (3D designed and printed) that support the plate and host the fishing line for the tilting mechanism.
Milling¶
Frame¶
The egg incubator frame designed and Cuted as process shown on ‘Week 07 - Computer controlled machining’
PCB Milling¶
PCB Heater¶
PCB heater board design with KiCad and milled with a 3018 CNC
The heater system ready to be assembled
Partial assemble of the heater system
Complete assembly of the heater system
Electronic design-KiCad¶
Control board was design in KiCad

What tasks remain?¶
The goals for our first spiral were all reached.
What has worked what hasn’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. Apart of that the rest was okay.
- We have to optimize our PWM Mosfet control for the heating system and redesign a better PCB heater.
Lesson learned¶
- Make sur you flip your PCB on The right AXIS
What questions need to be resolved¶
We have a working tilting mechanism but how can we ake it better? How can we make the whole product better and affordable
For a next spiral we have to add:
- efficient temperature control inside the incubator
- efficient control of 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.
- Log data for later analysis and use
