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.
