HOMEMADE EGG INCUBATOR COOLER HOW TO

If you only have two leads it is the same process although you'll only need a mono jack socket and the negative attached to the ground lug and the 12v attaches to the other lug. The 12v output form the transformer is the switched one and this is attached to the lug on the second layer of the output jack the put the 5v onto the third lug of the output jack, it doesn't matter which ones the 12v and 5v are on but the neutral must be on the correct one. Then take the neutral wire and attach it to the neutral lug of the stereo jack socket in my case it was the middle one but when you look at it side on it should be divided into three layers the top layer will be the neutral layer. The live (white) wire is connected to the relay i used a junction strip because I also wanted to put 240v through it. This is shown in the sixth photo I switched the live wire but you could just as easily switch the neutral. Then you want to attach the output leads of the transformer into a junction box i had 4 a 12v and a 5v but if you only have 2 it is the same process prior to this I plugged in the transformer and found out which lead did what the right two are positive and negative 12v. Now you want to put the temperature controller in and take two more wire out of the the junction strip and put them into the power input on the controller in my case 3 and 4 this will mean that the controller will always be on no matter what the position of the second switch.

The you want to take two wires out of the back of the junction strip and attach them to the middle lugs of the switch again keeping neutral on the left. Then you want to attach the input to the transformer to the bottom two lugs of the second switch, this will switch it from 240v to 12v, (if you don't want the choice you can attach the transformer straight to the other side of the junction strip), then put neutral on the left as in the second picture, I always have it on the left to make the wiring easier for myself. įirst you want to get three lengths of flex and attach two to the live and neutral of the bottom IEC socket, this will be the 240v in, then you want to take the live from the IEC to one of the two middle lugs of the switch then you want to solder another wire to the bottom lug of the switch but make sure it is on the SAME side the put the to in to a junction strip, the strip is about 30mm from the back of the temperature controller when it is installed.

WARNING - YOU WILL BE DEALING WITH HIGH VOLTAGES SO MAKE SURE ALL YOUR WIRING IS CORRECT BEFORE TURNING THE POWER ON!īefore we start always tin wires and lugs this means better electrical contact and its also easier to solder it together, if you don't know how to tin here is a good guide. This took the most thought for me although should be easy if you have a basic electrical knowledge. You will need: Materials: 1 - polystyrene box of at least 450mm x 350mm 2 - 185mm x 245mm x 20mm MDF 2- 65 x 245 x 20mm MDF (although I used 16mm) 2 - 105mm x 185mm x 3mm MDF 2 - 120mm x the width of your box x 20mm pine (not MDF as it will fail with the humidity) 1 - 85mm x 85mm x 20mm pine 1 - 85mm x 85mm x 3mm MDF 3 - 240mm long pieces of pipe insulation 2- 20mm diameter pipe the length of your box 1 - 20mm diameter pipe 13mm longer than your box 2 - Electronics: 2 - IEC sockets 2 - 10a, 240v, DPDT toggle switches (or rocker switches if you prefer) 1 - 1/4 inch mono jack socket 1 - 1/4 inch mono jack plug 1 - 1/4 inch stereo jack socket 1 - 1/4 inch stereo jack plug 1 - 240v to 12v transformer (I used an old laptop power supply) 1 - peltier cooler - 1- computer CPU heatsink and fan 1 - heatsink paste 1 - assortment of cables and wire 1- digital temperature controller - Tools: Soldering iron and solder drill and drill bits hacksaw blade bandsaw (optional) mitre saw (optional) pipe cutter router table (optional) The temperature controller is based around a digital temperature controller and has a dual output of either 240v or 12v this is so i can run my incubator and my wood kiln from the same box.

I used mainly wood and materials that I had lying around my workshop.

It was built out of a 450mm x 350mm polystyrene food box and can incubate a maximum of 8 eggs at a time.

all in all this project cost us less that £40 and works wonderfully considering that a shop incubator can cost £100s. Unfortunately for me this meant that my dad now want an incubator so i had to build him one. We have a few chickens at home but we wanted some more so we chose the ones we wanted and decided we wanted to hatch some eggs.
