Homemade incubator thermostat

An electronic incubator thermostat circuit shown in this article is not only simple to build but is also easy to set and acquire exact tripping points at various different set temperature levels.

The setting may be completed through two discrete variable resistors. Here the temperature is precisely optimized to match the natural incubating temperature level of eggs, which becomes the most crucial part of the whole system. The advantage of artificial incubation is faster and healthier production of the chicks compared to the natural process. The sensing range is quite good from 0 to degrees Celsius. Here we discuss a simple construction procedure of an electronic incubator thermostat.

This simple electronic incubator thermostat will very faithfully sense and activate the output relay at different set temperature levels from 0 to degree Celsius.

The conventional electromechanical temperature sensors or thermostats are not very efficient due to the simple reason that they cannot be optimized with accurate trip points. Normally these types of temperature sensor or thermostats fundamentally use the ubiquitous bimetal strip for the actual tripping operations. When the temperature to be sensed reaches the threshold point of this metal, it bends and buckles. As the temperature cools, the bimetal starts straightening to its original form.

The moment it reaches its previous shape, the electricity supply to the heater is restored through its contacts and the cycle repeats. However, the transition points between the switching are too long and not consistent and therefore not reliable for accurate operations. The simple incubator circuit presented here is absolutely free from these drawbacks and will produce comparatively high degree of accuracy as far the upper and the lower tripping operations are concerned.

We know that every semiconductor electronic component changes its electrical conductivity in response to the varying ambient temperature. This property is exploited here to make the circuit work as a temperature sensor and controller.

Diode D5 and transistor T1 together form a differential temperature sensor and interact greatly with each other with changes in the respective surrounding temperature. Also since D5 acts as the reference source by staying at the ambient temperature level should be kept as far as possible from T1 and in open air. Now assuming D5 is at a relatively fixed temperature level ambientif the temperature in question around T1 starts rising, after a particular threshold level as set by VR1, T1 will begin to saturate and gradually start conducting.

Once it reaches the forward voltage drop of the LED inside the opto-coupler, it will start glowing correspondingly brighter as the above temperature rises.

Interestingly as the LED light reaches a particular level, further set by P1, IC1 picks this up and instantly switches its output. Cut a piece of general purpose board about 1 by 1 inch. Solder their leads at the track side of the PCB; do not cut off the remaining excess lead portion. Cover the top with an opaque lid and make sure its light proof.

Preferably seal off the edges with some opaque sealing glue. Let it dry. The following paragraphs describes a simple yet accurate adjustable incubator temperature controller circuit which has a special hysteresis control feature.

It can be a fun project for yourself or to do with your kids. While store-bought incubators are convenient and offer additional features, building your own homemade incubator can yield excellent results.

However, there are many variations that can be just as successful. Feel free to modify these ideas to incorporate the parts you already have or can easily obtain. How Incubators Work The goal of an incubator is to maintain a temperature of 97 to degrees F at all times. An incubator with a fan is called a forced-air incubator. Because of this, you should aim for a higher temperature of degrees F. Your eggs need a humidity of 50 to 55 percent for first 18 days, and 65 percent or more for the last three.

If your incubator get too dry, your eggs may not hatch.

To control the humidity, adjust the amount of water in the baking pan. For the first 18 days, your eggs must be turned over two or three times per day. To help keep track, use a pencil to mark an X on one side and an O on the other to help you remember which side is which. During the last three days, you should not disturb your eggs at all—no turning. Step 2 Daniel Johnson Next, begin the slightly messy job of making some cuts to the cooler.

On the back of the cooler, toward one side, use a pencil to score the rough shape of the light fixture housing box as shown.

Then carefully cut this shape out of the plastic foam. Keep a vacuum cleaner handy! Insert the fixture box into its hole. Step 3 Daniel Johnson A glass window on the top of the incubator is very handy for allowing you to monitor the temperature, humidity and eggs without opening the lid. Again, score the outline of the 5-byinch piece of glass.

Use some clear tape to smoothly attach the edges of the glass in place. There are no hard-and-fast rules, so this is another aspect you can experiment with. You might opt to add more holes, even adding holes through the wooden outer case. If you think your incubator is getting too much of a draft, you can re-cover some of the ventilation holes with tape. Using a razor knife, strip away about 8 inches of the outer casing of the grounded electrical cord.

Snip off the ground green wire and set it aside for later use.Forums New posts Search forums. Articles New articles New comments Series Search articles.

Article Reviews 4 Gallery. This is the auto turn insert ready to be mounted, the rest of the pics are detailed photos of the rack. The motor is out of a battery operated 3 Volts rotisserie motor for a BBQ that I have mounted in a electronics box to protect it. The link strap has a channel riveted to it, from the motor is a arm like a bicycle pedal arm, at the end of the arm is a block that is sized to fit into the channel. The block rotates just like a pedal on a bicycle. Test fit into the Melamine coted chip board cabinet that will be the incubator.

Separating shelf in place with PC fan fitted, back of the cabinet fitted, light fittings mounted and some of the wiring running in to the micro switches that tell the motor to turn off when it reaches the right tilt point. Door fitted and weatherstrip to seal the door from draughts. The brains, the circuit board on the leaft is the picaxe based thermostat, it also includes a transmitter that sends data to my PC so that I can log what the incubator is doing in an Excel spreadsheet and display it as a graph.

The circuit on the right is the Auto turn control board. It makes the motor tilt the eggs from left to right every 40 minutes, or whatever I decide to program it to do. Closed up but not running yet, I have since removed the masking tape and fitted proper latches and fitted iron on edging to the bare chip board edges. First hatch, some cross breed eggs that were not a huge issue If there were any bugs on the first run, the second set of eggs in the rack are at day 2. And a close up of the Babies as I cant resist Chicks.

Latest reviews ronott1 3. Well this is one that is probably too complex to be replicated by others. I would have loved more detail on how you programmed the turner and how you actually connected it to the shelves. Would have liked to know more about the build and the circuit, but the pictures definitely help form some ideas of my own!

Any chance you have an illustration of how you geared the motor and put together the strap.Our start with chicken-raising was very cautious: a tiny flock of ten pullets and a cockerel, obtained from a hatchery. The day-old chicks were carefully tended, kept warm and protected from drafts by a homemade brooder — a cardboard carton heated with a light bulb — in our empty guestroom for a few weeks.

By the second week the babies' wings had developed and we discovered them flying around the room and alighting on various objects. We clipped their wingtips at that point, constructed a broiler house from miscellaneous scraps of wood and wire and — when they were sufficiently grown — moved our birds to their outdoor quarters.

Five months later we discovered our first egg, and gathered the fresh, fertile layings faithfully each day for many months afterward. By the end of each week during that period, we always had at least a dozen extra for sale or gifts to friends.

Meanwhile, meat prices were rising steadily and we began to consider keeping more chickens for slaughter. Then spring rolled around again, our neighbors began ordering new chicks from the hatchery and we discovered that the cost of day—old biddies had doubled in our area. That's when we decided to try hatching our own fertile eggs. The only trouble with this idea was that all our books manuals and brochures on poultry-raising told us to begin with day-old chicks.

We could find no information on incubation of the eggs, not even under a broody hen. A mature layer of one of the maternal-minded heavy breeds will manage the job quite nicely but she'll pick her own time, and it probably won't be as early in the spring as you could wish if you're in hurry to establish a productive flock If your chickens are leghorns or one of the other light types, you'll probably need an incubator in any case to compensate for their lack of motherly feeling.

Finally, after much searching, we turned up some help in several old, worn volumes. The rest of the information in this, article we learned for ourselves by building and operating our own incubator.

An incubators is a device that provides controlled conditions for the hatching of eggs. There are three basic types:. Still-air incubators are warmed by uncirculated radiant heat, and the placement of the eggs in relation to the heat source is critical. It's also just as important to locate the thermometer correctly. A wrongly positioned instrument will be inaccurate by several degrees — enough to cause the failure of the hatch or the death of any chicks that do emerge.

The air must be flushed thoroughly from the apparatus at least four times a day when the eggs are turnedto release the noxious gases that accumulate in the closed box. This type of incubator has ventilation holes in the top and bottom to provide a continuous flow of fresh air and an even distribution of beat.

The upward draft in the chamber causes fresh air to be drawn in at the base of the device. It's then warmed by radiation and circulated around the interior. Placement of the eggs and the thermometer are thus much less crucial than in the still-air machine. The disadvantage of this method is the higher rate of evaporation created by the air currents. This means that relative humidity must be maintained by the use of evaporation trays and carefully monitored with a device called a hygrometer.

Incubators of this type are also vented, but air and heat are circulated with a fan instead of by convection. Again, care must be taken to maintain proper humidity.

The mini-hatchery we built to increase our flock is of the convection type.

It was inexpensive to construct, isn't at all elaborate and — while far from ideal — gives good results with careful attention and maintenance. First — because accurate temperature control is vital — we ordered an electric thermostat switch from Sears check for such items in farm supply catalogs. This was our only piece of store-bought equipment. While we waited for the thermostat to arrive, we lugged down from the attic a deep wooden packing case that had contained bottles of a one-time popular soda beverage called Clicquot "pronounced Klee-Ko," we were told by the lettering on the box.

We cut a lid to fit from scrap lumber and lined both the antique crate and its cover with heavy-duty aluminum foil to provide reflection of internal heat.

An aluminum pie plate was placed on the floor to serve as an evaporator tray. Then we took two screens of half-inch wire mesh and fitted them on a ledge of 1 x 2's laid on edge at the incubator's bottom. Our heat source was four small watt light bulbs any size up to 25 watts would doone placed near each corner of the lid and connected to the thermostat installed in the center.

We hinged the cover and drilled one half-inch ventilation hole in each of its corners, also two quarter-inch holes in each side of the box, about an inch above the level where the tops of the eggs would be. Our incubator was complete.JavaScript seems to be disabled in your browser.
