Little Brown Egg I: Condo-Q
Sunday, July 10, 2005
Barbecue is one of man's earliest and greatest inventions. The practice of cooking meat slowly over low heat and smoke produces food of incredible taste and texture, with a flavor that is completely irreproducible by any other method. I've often longed for the chance to produce my own slow roasted smoky goodness, but I'm sad to say that I live in a state that prohibits condo owners like me from operating a gas or charcoal smoker. Stupid fire codes!
I've been a student of all things Q for several months now. My inability to produce my own variety of homegrown goodness didn't stop me from spending hours reading the Rec.food.barbeque FAQ, various cook books and magazine articles. It seemed like I was torturing myself and that I'd never be able to live the dream, until one day my culinary hero Alton Brown showed me the way.
In an episode of Good Eats he detailed a method for constructing a condo-sized electric smoker from a hot plate, two large flower pots and a few charcoal grill components. At last, salvation! You see, since there is no open flames the smoker is legal for my domicile, and the small size makes it easy to store on our little back porch!
I immediately set about creating my own smoker. Behold...the Condo-Q!
Ok, so it's no Big Green Egg, but it only cost me about $70 to make. If you break it down, you can see the component parts and how it goes together.
The bottom pot is a 14" terra cotta pot from Wal-Mart. The hot plate inside was an all-metal 1500W unit I bought on E-bay. The Char-Broil grill thermometer and 13.5" smoker grate came from Home Depot. I got an el cheapo steel pie plate (holding the burnt hickory chips) from a local housewares place. The hardest part was finding the shallow pot for the top (I got it at Pike Nursery). The pie plate rests directly on the burner, with the grate going inside the bottom pot. I got really lucky in that the grate fits perfectly inside the pot, resting right on the inside lip where the taper starts!
What's that black box you ask? Well, that's where the weekend tinkering stops and the obsessed engineer starts. The first time I fired the smoker up for a test run the hot plate blew out. You see, the hot plate had a heat-sensitive fuse that blew when the unit overheated in the closed space. Since I was already taking the hot plate apart, I decided to go one step further and relocate the controls outside of the smoker. That way, I'd be able to turn the heat up or down without removing the lid and wasting valuable time! I will rule the world!!
I ordered an enclosure and some high-temperature wire from McMaster-Carr and got a new (replaceable) fuse holder from Radio Shack. I used high temp wire because I didn't want the insulation melting and blowing up the smoker. I mounted the control knob in the enclosure and wired the box up, being careful to replicate the wiring layout that was in the hot plate. I also used a terminal block so that I could fasten and remove the hot plate leads to assemble and disassemble the smoker for storage.
I affectionately call my creation the "Little Brown Egg". I built the egg several months ago, but had to put the project aside to concentrate on other things. If not for another blogger's post, it'd still be there...
How did it turn out? Check out my follow up post where I put the LBE to good use...

Are you sure that the control mechanism you've created in the radio shack project box isn't just a fancy on-off switch? I've disassembled a different brand of hotplate before (for this very purpose), and the best I can figure is that the rotary dial is an adjustment knob for a bang-bang thermostat, not something that would adjust the level of heat output by the coil. i.e., it measures heat, and if it is less than the dialed setting, it switches on the heat element.
My best guess is that by removing the thermostat from the smoker, all that happens is that if you dial the thermostat above the temperature outside, it turns on, but otherwise, it turns off.
Let me know if you have any evidence to the contrary--I'd be happy to be wrong, as I'd love to have a rig like this with a cheap temperature control.

From what I can tell, the knob controlls a bi-metallic thermostat. The question is where does the heat come from to move the thermostat.
The knob does control a "bang-bang" thermostat. The question for me is where does the source of the feedback come from.
I've assumed that the current flowing through the thermostat moves the strip. The other possibility is that the heat from the element heats the enclosure and activates the thermostat. If the latter is the case, then the knob would be useless when removed from the hot plate.
From my observation, my control box gets plenty hot during operation (hot enough to make me think the resistance of the thermostat itself drives the feedback). And I've also observed that the knob definately has an effect on LBE internal temperature.
So I'm assuming that my theory is correct. However, different hot plates may have different methods of control.
As to it's effectiveness, it's pretty good. The LBE takes a long time to heat up and cool off due to it's ceramic housing. So I don't need the accuracy of a proportional control thermostat.
Didn't know much about thermostats before your question (I barely made it through controls class in school). Thanks for the education!

Hey dude:
Thanks for stopping by my blog and providing links to your LBE project. Your skills as an electrician--not to mention perserverance--put me to shame. My own LBE project fizzled. First my hotplate wasn't up to snuff. Then I replaced it with a butane-powered paella ring burner. It worked great for three hours, then died without explanation (and no...I had a full tank of butane).
In the end, I bought a WSM from Amazon.com for $200...and then spent another $220 to ship it to Spain. Ah hell...it was worth it. It should last me 20 years...during which time I will be one of the few men in Spain eating true Q.
But still, I wish my LBE experiment had worked. Just once.
Congrats on your successes (chicken looked fab!). If I lived closer, I'd donate my wrought-iron stand to you.
Cheers!

Way to rip off Alton Brown.
6/25/2006 1:22 PM
You must be new here...I rip off AB quite a bit. What can I say, I'm a fan.
Besides, I like to think I took the GE smoker to the next level with my custom control system.
6/25/2006 1:23 PM
I made the previous DIY Smoker mentioned in MAKE and I think think you'll miss the problem I have with my trashcan model, namely that I can't get the temperature high enough. The 1500W burner (mine is an 1100) and smaller internal space to heat will probably give you a heck of a good cooker. Good job!
6/25/2006 2:28 PM
Thanks! Yeah, the temperature is pretty consistent. My biggest issue is wind blowing in between the two pots. I need to get some weather stripping to create a gasket between them. Currently I can only get to 225 or so, but I'm hoping that that mod will get the temperature up faster and more consistently, and help reduce smoke loss through the sides.
6/25/2006 3:21 PM
In order to get the temperature higher you should put your pot into a larger pot and then fill the space between the two with vermiculite or lava rocks. This will also help to maintain a more consistent temperature.
6/25/2006 10:59 PM
Whoa! That'd certainly work better. The good news is that in most weather it'll maintain 225 brilliantly. That's more than hot enough for serious BBQ action. The important thing is to make sure there's enough air flow for proper smoking.
Fortunately, I live in Hotlanta, so I don't have to worry too much about it. If I lived farther north, it'd certainly help.

Living room fireplace! Opened the chimney damper, put my "egg" on the firewood grate and ran my "decorator orange" extension cord across the room. Who cares about cold or wind?! I'll have Q all winter long - in New England!!
Chicken was great! Split, whole chicken, about 3.5 lbs - olive oil, fresh rosemary and oregano, s&p. Three handsful of soaked hickory, 3 hrs cooking time (hickory lasted the whole time).

Hats off to you. Nice job. Only comment I have is, you said it cost you $70 to make. Plus,your time putting it together? You can find electric smokers anywhere for about $100 onsale. Not sure about other people but, I don't think a lot of people want to mess around with putting elect. controls together. Just my opinion. Again, Nice job on that.
1/24/2007 11:36 AM
Sure, once you figure in time, then it's probably not the most practical way. But then again, a project like this isn't about that.
Right after I finished, I saw a Brinkmann electric smoker for $80 at Home Depot. It put a little damper on my egg, but I think I still like mine better. Your results may vary.

I was reading a couple of your past posts. Just wondering, do you ever soak your wood chips in wine or bear? It adds so much to the flavor. At first it may be a bit much for some people. When I first tried it I mixed about 1/2 water and 1/2 wine or beer. Tip: Use good dark flavorful beers and heavy of fruity wines. One of my Favs is beercan chicken with applewood soaked in apple or cranberry wine. just put wine in the can instead of beer or, cherrywood soaked in Sam Adams "Cherrywheat" beer. Tip: stuff black cheeries under the chicken skin.
1/25/2007 8:58 AM
I've never done that, but it sounds pretty cool. I'm aiming to try more new things this smoking season. I'm a bit bored with chickens!

Thanks for this excellent post, the question of the external hot-plate control seems to come up over and over.
So, what if you just did something super-simple and wired together a cord, dimmer switch, and duplex outlet? The cord would plug into the wall, the hotplate would be turned on hi and plugged into the duplex outlet, like this:
Wall >> Cord >> dimmer >> outlet >> hotplate.
Wouldn't that let you regulate the power to the hotplate using the dimmer switch? Obviously I'm no engineer... just a guy with a bunch of dangerous parts... but it seems that a hotplate would probably draw well under the 600 watts max rating on most dimmers.
Hmmm, this article talks about dimmer-switch TRIAC and maybe that is good, maybe bad: http://home.howstuffworks.com/dimmer-switch.htm
Can't find a similar article on hotplates darn it, only on toasters... ;-)
(These kind of questions probably explain why I have several fire extinguishers around the house.)
No matter what happens I'll be trying this soon: a buddy was raving just this weekend about the 16-hour falling-off-the bone pulled pork he produced from the flowerpots... and he actually has a gen-u-wine Little Green Egg sitting right beside the AB smoker! Both are pretty good at doing what they do, but when you're an Alton Brown fan it doesn't matter what you already have: you gotta try it the "AB way"!!!
Thanks for any feedback, and keep on cookin'.
1/31/2007 12:15 PM
Great explinations... 'ripped off' AB as well and love the results. I have one concern though. Two of the three times I've used my pot smoker the temperature inside has rather suddenly spiked well over 250. In one case I had stepped away for 20 minutes and the thermometer read 325! I don't think my hotplate has the power to do this on its own, so I have theorized that the hardwood is igniting and the burning is causing the temperature to get out of control. Thoughts?
By the way, I didn't have the time to relocate the controls so I just drilled out a hole just big enought for a small screw driver in the side. Then used some high temp silicone to set the plate in place. This way I can make small adjustments and maintain more or less constant temperature (minus the spikes of course).

Anonymous, that happened to me too when I first started using the LBE.
First off, it's super-important that you soak the wood chips in liquid for an hour before smoking. This will prevent ignition of the chips.
Second, use the heaviest pan you can find. The lighter pans create major hot spots that can light the chips on fire. An old, worn out cast iron skillet is best.
Finally, if you still have problems with ignition, use sawdust or smaller chips. The smaller the fuel, the more smoke produced and the less likely you are to have a volcano...
Good luck!
5/13/2007 12:24 PM
Hi, I just saw this episode last night and am in the process of making my LBE. One question, have you tried charcoal instead of the heatplate? I'm guessing not because of the condo restrictions you mentioned...
The reason I ask is because one of the advantages of other ceramic cookers is the incredibly high heat you can attain in addition to the low temps you can maintain. I'm guessing the flower pots can't handle high heat anyway so its probably not even worth trying.
At any rate...have you tried salmon at temps around 150*? I saw AB's cardboard box but that was kind of ghetto so i'd want to use my LBE for that.
5/30/2007 6:41 PM
Simply genius! I am going to try this and try using a thermoconductor feedback loop with an old "Love" controller from an industrial salvage yard. instead of a hot plate going to try to wire in a stovetop replacement element.
Hope you don't mind I linked to you from my blog. Let me know if this isn't acceptable and I will remove the link
7/12/2007 7:22 PM
I am trying to build my LBE. We have gone through 3 different hot plates. We switched from a 750 watt to a 1000 watt based on what I have been reading from other peopels posts. And well we still can't get it to work. I know minimal about electriacl stuff. I was wondering if someone coudl walk me though how I should approch the problem of not being bale to get the teperature hot enough. Thank you please E-mail me at rustybeachboy826@aol.com

After melting the solder joints on my Walmart hotplate several times I "hotwired" the heating element by physically removing the internal thermostat and built an external thermostat using a GFI plug and a 600W dimmer switch. The GFI and the Dimmer switch are mounted in a standard, blue plastic 3-gang remodeling box with a 15amp, 1875 watt grounded appliance tail comming out of it. Hot plate plugs into the GFI, Voltage to the GFI is controled through the dimmer switch. Presto, you have a GFI protected thermostat. I can keep my LBE at 225 for hours on end. Add wood to your plate, turn the dimmer up. Wood starts burning on its own creating coals, turn the dimmer down. I started with a two-gang box, but things got a little tight given that I was using 12ga wire inside and had the appliance tail to contend with, so I moved to the 3-gang box. I am toying with the idea of moving the "thermostat" to a surface mount exterior box with a cover. The 600 watt dimmer switch can get a little warm after a few hours, but it's not exposed to anything combustible and if it were to blow, the GFI will cut power. Should probably be using a 1500 watt dimmer, but the 600 watt has been working for two years now with no problems.

To the person asking about charcoal...
I made a LBE and got the bright idea to put some charcoal in the bottom to get some nice barbecue action going on.
The sucker cracked right down the middle, and I had quite a problem on my hand seeing as how I was cooking on my apartment balcony.
12/24/2007 9:09 AM
Just a heads up, for 28.88 you can buy a charcoal smoker at Walmart (Smoke N' Grill by brinkmann" and retrofit it with a 1500W hotplate, or, a specific heating element for sale at Cabella's (on their website) which lands you in at 60 dollars with twice the smoking price.. and it works wonderfully! I finally gave up on my nieve quest for the flowerpot smoker and opted away from the trash can smoker because I was rather concerned about inhaling much zinc vapor from the galvenized pail. Either way, your idea is great and looks like lots of fun.

Dude, This is amazing.
I have a Brinkmann firebox smoker that will hold 15 racks of ribs.... but this one you have is the BOMB!!! To all the people who are blogging about getting a smoker at walmart or somewhere else for 25-100 bucks, I have one word...ok its two.... Terra Cotta. I live in northern Illinois. It gets darn cold here in the winter, and 1/8 inch steel DOES NOT HOLD HEAT. Try keeping a thin skinned steel smoker at 225 when the ambient temp is 12 degrees. It is seriously a pain in my shorts. These thick terra cotta vessels are PERFECT for holding heat. That little green egg that costs 600 bucks can do several racks of ribs on about 2 dozen pieces of charcoal. It can do that because of heat retention.
Terra cotta is the tinkering smokers best friend.
Alton Brown is my hero. I have modified serveral of his recipes (ya, I use Famous Daves or Bandanas rub), but he has it right on the basic works of the smoker.
If you want cheap... check out his cardboard box smoker. It works and actually works pretty good. You just have to get a new box every time and make sure it does not catch fire.
Happy smoking. I am getting ready to smoke an 8 lbs brown trout this weekend.
SMOKERS RULE!

Tried this smoker myself and have run into a problem: I can't get the temps above ~150 F. I am using an extra stovetop-type element, not a hot plate, so it should produce plenty of heat. The only difference with mine is that I am using a flat saucer-like top instead of a rounded pot on top of the main pot, and I only left 3/8" of circulation beneath the last time I tried it. I don't think either of these should be too big an issue (in fact, I'd figure the flat tope should make things HOTTER). The only other thing I can think of is that the heat element, instead of a fuse, has some sort of reset circuit for when temps get above a certain point. Any other ideas?
6/13/2008 10:29 AM
I have had the same problem listed on several boards of only being able to achieve around 150 degrees. I ended up figuring out that there must be some manner of thermocouple in my hotplate that stops it if ambient temp goes up too much. I ended up buying a different one made by Toastmaster. It ended up being the cheapest one i had seen yet.
It works like a champ.
I intend on taking the other apart and see if I can't bypass whatever mechanism is stopping the overheating, but in the mean time, I'm up and smoking with a big ole flower pot. I'm taking on a 9 lb. Boston Butt in the morning. :)~

@Josh
I'm guessing the range element you're using is supposed to be used with 240 V, which explains why you're not getting the power you need.
