Step 1: Tools and Supplies You Need

We will be need

1x 12v Thermostat controller

1x 12v computer fan

1x 5 feet 23/73 220v wire

2x 2 feet 23/73 220v wire

1x 100 watt bulb

1x bulb holder

2x 12v adaptors

2x 12v plugs

1x 220v plug

Handfull of zipties

Tools you need

Wire cutter

electrical tape


Drill machine

For the Egg tray

Big plastic tray

2x 15inches wood

2x aluminum bowl

Step 2: Drilling the Holes for the Wires and Parts to Fit In

We need to drill holes on the points where I marked

from the sides the wires will come in from the front we have to make a 4 holes for circuti wires and 4 holes for sticking the circuit

from the other side below side fro the heat source bulb

and from the down side 4 holes for the fan so it can stick to the surface

Step 3: Wiring All the Components

I have insert the wiring of 12v wires one is for the fan and other is for the circuit both of them will work on 12v

wire the fan properly and also give supply to circuit

look carefully where I put the ground and 12v black wire will always go in GRD and other will go in 12v

Step 4: Now Is the The Time to Shine for Bulb

Now tighten the fan with ziptie and make sure the sticker part of fan is facing the heatsource the bulb so it blew aways it's heat and distribute in evenly in the whole incubator

Wire the bulb holder and tight it with ziptie

The hard part is that you have to joint the bulb wire by another wire

There are two wires going in the main wire cut half the wire and cut only one wire of it and joint them to the new wire and it will go into the circuit K0 and K1

see the pictue carfully of how to hook the wires

attache the wires to Ko and K1

wires up the 12v female sockets and 220v plug in there wires

Step 5: Make the Support for the Egg Tray to Sit

Measure 7 inches from the ground to attach wood panels with the screws

put the tray on top of it

put those almunium bowls on the box ground

Plug in the Incubator

Voila Your incubator is ready just put some eggs in the tray put the water in almunium bowls and you are ready to hatch chicks out of eggs

    It would be even better if you could add something that would rotate the eggs too. That was the really inconvenient part of hatching chicks when I was in college. Someone had to come in on weekends just to rotate the eggs.

    Keep seeing the same basic mistakes in homemade incubators:

    1 - Incubating eggs breathe (need oxigen, release carbon dioxide)...I see no air vents in your incubator...

    2 - Only one lamp as a heat source... If it blows out (say during the night), there goes the hatch... Instead one 100W lamp, try connecting 2 x 50W in parallel...

    Very good pointing out I forget to include vent holes for fresh air coming in,putting two bulbs is also a good option.
