Title: Selectable temperature (Testing complete)/Plans
Post by: msiler on March 18, 2004, 07:38:57 AM
I am in the process of building a 'brainbox' that will allow me to select a specific temperature. I have in the past built one that would allow one specifice temp. I intend this one to be adjustable for a variety of temps.

First question is has anyone done this already? if so I would be interested in information on how you did it (no sense duplicating efforts) or even purchase of one.

Next question is do any others have interest in this item, if so when finished I will make this available to others.

When in doubt smoke it.

Although, I do not have a full Bradley unit, I purchased a smoke generator and am converting an old fridge, I have figured out a temp control device. I purchased a temp controler from ebay for $20. It is digital, shows the actual temp, has an alarm and allows you to set the temp. In line with this I will install a J coupler (temp probe) to sit inside the fridge. $12.00. ALthough not really required I will use a relay box $5.00 to protect my temp controller. The whole thing is then wired to my hot plate( which is only used to produce heat, the same way your bulb does)The temp controler came of off a piece of industrial machinery. I am presently putting the pieces together and will attempt to send pictures when complete. I am not sure if you can do the same in line with your bulb. Isnt the bulb wired directly to your smoke generator.

A hot plate is a very durable heat source.  I wonder what the effect would be on the heat bulb if it were switched on and off all day.  Would it shorten the life of it?  I would assume you would have to switch it at max voltage to allow you to maintain the whole range of temps up to 250f or so.  I'm not a heat bulb guru, but just something I wonder about.  Maybe these bulbs are cheap and its not an issue.  Has anyone had to replace their heat bulb yet.[?]

Trout,
I have not replaced my heat bulb, but Chez has them listed on his web site for $15.00.

I am actually trying to figure a "Smart" circuit that would adjust the resistance much the way I do the rheostat... only with an electronic brain instead of my human one that has to sleep... which sometimes allows my overnight cooks to get a bit out of control....

I have dealt quite a bit with plc's at work.  They would work well for something like this.  The only problem is that the temp change is not instant.  You would have to program it to monitor temp, adjust an increment, run a timer for 5minutes, adjust again if necessary and so on.  I my self have a 1yr old baby [8)]to keep an eye on all day on some of my days off.  So I welcome the need to have a smoker to keep an eye on during the day.[:)]

Guys,

I too would be interested in the unit you're suggesting. Just like Kummok's Advancing Pucks, we would also be interested in offering them for sale if that interests you.

Regarding the bulb life, we have never sold one to anyone who has burned one out. I'm sure they have some sort of lifetime, but I don't know what it is. In our experience it's always been human error.[;)]

I am testing what will hopefully be my last prototype. it is holding temperature within 2-3 degrees empty. Tomorrow comes the first operational test with food and pictures will follow. For those who are interested total cost was about $75 in parts. And thus far no actual mods to the smoker. Just plugs in between the smoke unit and the box and for now the temp sensor is fed in through the vent like the meat thermometer.

found this on the web..http://shop.homebbq.com/prod_images_large/guru_package.jpg

This is $185 but I don't know how it would work with the Bradley...visit homebbq.com...

Anyone would agree that a hot pit cooks quicker than a cold pit. The problem is that when the internal meat temperature over-shoots or goes
too high, the meat becomes dry, tough or both. The BBQ GURU uses a microprocessor chip to calculate and control your pit temperature via the Turbo Power Draft Fan , so that the selected meat temperature is NEVER exceeded.

How does The BBQ GURU do this?



Simply put, as the meat temperature increases or “ramps up” The BBQ GURU decreases or “ramps down” the pit temperature at a proportional rate using controlled power draft. Once the intitial ramping is complete, the Guru maintains the pit temperature throughout the cook to ensure a consistent and effective cook.



Once you use The BBQ Guru, You simply will NOT want to cook without it!

• Electronic Control with Sensor Probes
• Custom adaptor door for YOUR grill/smoker
• Turbo Power Draft Blower

I've looked at that before & although very intriguing, can't imagine they'd have an application with the Bradley. They limit the combustion of fuel by restricting the airflow, which wouldn't affect the electric bulb.

I doubt the unit has enough power to effectively horse through enough air to actually cool the inside of the smoker. Even if it did, say goodbye to all that lovely smoke.

JMHO, if somebody can show me differently, I'd be in line to buy one.

I am happy with the results so far. but I am going to do further testing this weekend with brisket to ensure that my long cook time last weekend was solely due to chicken size. 2 chickens took about 10 hours at 200 degrees. "Book time" should have been about 5 they were my first yardbirds in the bradley and most recipes I found call for much smaller chicken than I have found. So after I do up some brisket this weekend I should have a better comparison.

ALL I to am experimenting with my second attempt at temp control. This time I went to an appliance parts store and bought an oven temp replacement control that comes complete with the jcoupler(temp probe) wire, light to say when it is on etc. The whole thing cost about $40 USD. I will use it just like you do an oven. Set the temp and the thermostat will turn the unit on and off to keep the temp constant. (Just gotta figure out how to wire it with out blowing all the fuses in the house)

What I used was an oven controller. Although it cost me $50 plus tax just for that and about $15 plus tax for other bits and pieces. I can offer some help for others who would like to do the same or I could be convinced to do the labor and sell a few. And yes come to think of it I do have a paypal account.... Before i would sell any i would have to research to see if i can get cost down some more.

Here in Homer, D Cell batteries are considered high tech!! Finding an oven controller would mean looking for the impossible at the one Safeway store in town[:(] Besides, I'm one of those that believes that electricity is magic so I'll keep watching for your finished product and compete to be your first customer[;)][:D]

When you perfect the temp controller, you could develop a linked timer so it could be set to incrementally raise the temp the way I do manually now for fish[:D][:D] Course, I guess that would pretty much spoil us rotten, but what a challenge, eh!?!?[;)][:D][8D]

msiler I have the oven controler I have just been a little nervous about attempting to wire it. Should I experiment with another electronic device (light bulb etc) and keep blowing fuses till I get it right? What do you suggest?

Do you have the wiring diagram for the controller? If so it should be fairly easy depending on you abilities if not I would not recomend trial and error. It is not rocket science but could cause a real problem if not done correctly.

Post by: Oldman on April 20, 2004, 12:14:17 PM
A thought here.... if you are using home type instead of commercial temp. controller you might find that the temp will vary up to 10 degree both ways from your setting.

Ok M....it's been awhile since I've been back to this topic, so I was wondering how your experimentation is doing thus far...

Have you reached a final product?
Results?  
Electrical (circuit breaker/fuse) issues?
Final cost (please to include labor cuz time is money too)?

If you need to make more and have available testers, I think there is Kummok, Chez, Fuzzy, Olds, Snapper all willing to "test" your product before you mass market hee hee! - You know, just to make sure they work properly in the field and different climatic environments around the country....

Maybe just print up the plans and sell the plans?? (To Bradley?)

Olds you are correct, the thermostat may be off by up to twenty degrees. Once you understand how much it is off the you adjust accordingly. I dont think it will evr take away from a seperate thermometer. I plan to set mine (when I figure out how to wire it) with a thermometer ignoring what the dial says and go from there. Besides when you buy one of these thermostats the numbers for the dial are not even stuck on you have to do it yourself, I think so you can calibrate the temp before sticking it on ???

Ok I am ready to call testing complete and share plans...
Sorry it took so long folks.

It does seem to have extended my cook time somewhat.... Probably due to better control ie. no overtemp excursions etc.

The way I have wired it there are no modifications to the smoker just plug it in between the smoke generator and the main box and run the probe in through the vent and hang with some stainless wire. I looped the extra capillary tube and stored it under the back cover.

I also limited travel of the temp knob on mine as to not be able to accidently overtemp, I did this with a small pin drilled into the knob and another into the face of the box.

If you do not feel up to this task and still want one let me know and I will see what I can do to help.


Parts required:

1 Oven thermostat Part No. RS-5430-175
1 computer cord make sure it's same gauge or heavier than smoker cord
1 box at least 3x3x2 internal dimensions
solder and heat shrink

Here is the wiring diagram
