Memories of the past…

Sam was a big black man.  Retired cop if I remember correctly.  Back in the late 80′s, early 90′s he ran a BBQ restaurant in the little town of Rutlader, Ks.  It was self named, Sam’s Barbecue. I worked there in the summer of 91.  I remember Sam told me I was the only white person that had worked for him, which back then, for me, was not very reassuring.  But I received free meals, and the food was pur-fect!!!  I didn’t mind.  It was money and actually I think he yelled at his son (whom was my age) more than me.  I won’t ever forget the dish washer though.  It was right next to the firebox, where they would smoke the meat.  Even with the air conditioner at full blast, I didn’t feel a thing but the scorching heat!

I think it was the entire ambiance of this morning that made me think of the old place.  I remember a few of the Summer mornings when I was going into work early, the air would be cool, foggy and the sun would cast it’s morning glow against the apple smoke slowly rising from the building. Have you ever been to Rutlader?  If not, you aren’t missing much but some nice country side views on your way, 7 miles south of Louisburg, Kansas.

You go down there today and you would have never known it was there. A big RV park, the Rutlader Outpost, and Middle Creek Theater are there now.  I drove by recently and honestly don’t know if the original building is still there where Sam’s use to be.  I really don’t recognize the place.  I really wish it was still there.  I’d get a kick out of seeing Sam today, and man how I loved those burnt ends.  I swear he had a five gallon pan of those things always cooking on the stove.  I sure do miss those days sometimes.   If anyone reading this happens to know where or what happened to Sam, I’d love to hear.  Last I heard (in 1991) that he was wanting to move his business to Overland Park somewhere.  I don’t think that ever happened.  Sam’s BBQ didn’t stay around Rutlader much longer after I left.

WiFi BBQ Smoke Thermometer

It was a great fall weekend!  Weather was great so I figured I’d put a few burgers on the grill and do an initial test of my first  version of the Wireless (WiFi) BBQ Smoker Thermometer.  I came up with a grand idea after a few coffee talk discussions with some guys at work.  Herein lies the details of the device and a little creation theory as to why I built the device in the first place.

It’s no secret.  Good barbecue comes from ultra-slow smoke cooking.  There may be no such thing as slow cooking a pulled pork too long.  The more you can let the beast brew and stew in it’s marbled fat the more tender and flavorful the meat will be.  I have my own personal recipe that requires around 16 to 18 hours of smoking.  That’s a long time.  And if you are like me I don’t like to leave the house too long, as I worry about something unexpected happening and the temperature rising too high or worse… the breaker tripping!  It would be great if I could go to work or do all my errands on a weekend Saturday and be able to pull up a web-page on my iPhone to see what the current temperature of my smoker and meat was.  Figuring out a solution wasn’t that hard.  After about a month of designing and prototyping I had my first unit to test.  That first test was excellent!  So I figure I would document my experience thus far for anyone interested, and hope that if you come up with different creations to please post them here for all to see.  I expect to have 2 or 3 more versions after this one.  I’d like to have the ability to have my device control my electric smoker via a relay, as a sort of thermostat, and I’d also like the ability to have an emergency stop that I can send via the same web-page I use to view the temperature.

Here is a little description of the devices components with more details as well as the code for you to improve off of!  The heart of my WiFi BBQ Smoke Thermometer is the Arduino Uno.  Arduino is an open-source electronics prototyping platform that can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators.  It’s programed using a simple language self titled Arduino Programming Language.  I added a pre built add-on (called a shield in Arduino ‘talk’) that allow the device to connect to my wireless router.  Then with a few other various electronic components as well as some temperature probes and free on-line software service, pachube.com, (pronounced “PATCH-bay”) had my device made!

Here is an itemized list of all the components that made up version 1 of my design:

Qty         Item                                                                                      Site

1              Arduino Uno                                                                      Sparkfun

You will more than likely be able to find some of these items elsewhere or at your local Radio Shack, Fry’s, or general Electronics store.  Speaking of electricity.

Time for my legalese.  This stuff discussed in here deals with electricity.  Electricity can kill.  Therefore since I’m just a general and lowly man, I absolve myself from every and all liability.  If you aren’t sure about something consult someone who does or find another project to test and create.  Don’t risk playing with your life.

Credit:  I give credit where credit is deserved.   My design is largely sourced from the design by Luke Miller.  You can find his original creation here.  While I was spending a week researching the items I would need, I ran across Luke’s site, and was relieved to see that over 3/4 of what I needed to do was already very well documented by him!  Thank you Luke!

So How is this thing going to work?  Okay!  I get it.  You wanna start smok’n!  Slow down!  You can’t rush this stuff!  lol.  Here is how all this stuff put together is basically supposed to work.  I’m going to start from the beginning for those of you who aren’t familiar with the Arduino and stuff.

The Arduino is basically a mini computer.  It ships without an “Operating System”.  That is what you will need to supply.  The operating system is going to tell it what you want done, and how to do it.  And here it is… the obvious.  There isn’t any ‘windows’ or ‘start button’ or fancy things like this with this computer.  Think of it as you re-inventing the wheel… starting where Bill Gates or Steve Jobs did with the first personal computers.  You are re-writing history my friend.  You are going to create an operating system for your Arduino that is going to explain to it how to read the temperature probes, convert the reading to something useable by our human brains (it’s hard to read a bunch of zeros and ones 00010100101010010010101010001010100).  This operating system is also going to explain how to get it connected to the WiFi shield, and it’s going to tell it to listed for you to press the buttons, etc that you wire into the box.  Fear not though.  It’s can be complicated, but I will be nice and supply the source code for you.  But don’t stop there.  Feel free to play, change, and improve on my method.  That after all is part of the “freedom” that comes with using the Arduinos.  A quick Google search will return millions of pages where authors have contributed there code and wiring designs to the public community.  It’s an awesome device all the way around!

Operation:  For those requiring a bit more detail into the intricacies of this version of the device, here you go.  The device can handle up to 3 temperature probes.  The probes are basic thermistors.  Thermistors are a resistor whose resistance changes according to the temperature.  That’s what the arduino is good for!  It measures the resistance and does the nasty calculation to get it readable by us in a Fahrenheit conversion.  I’m going to venture to guess that the probes aren’t readily interchangeable with other probes you find.  The specific model of my probes is “CDN AD-DTTC Replacement Probe For DTTC-S, DTTC-W Models”.  You can Google around and find a few exact replacements.  If you do find another probe that is cheap and works let me know.  If you find one that doesn’t work, you will need to recalculate the coefficients and replace them within the program of the Arduino.  Note that these probes are rated to 400 degrees Fahrenheit which should be plenty for smoking with.  When you plug in power for the Arduino, the program start right away asking if you want to connect to WiFi.  Press the choice button once for YES, or leave it for a few seconds and it will assume NO and continue to the next 2 questions (the remaining 2 questions ask you for a low and high limit.  The Arduino is configured to turn on an output line which can be wired to a relay to configure it to maintain the temperature of your smoker within the specified range.  You would need a separate relay that has enough amperage to handle your specific smoker based on it’s wattage.  I didn’t include this in this version of the device, although I left the code in from Luke Miller’s version if you would like to use it.  I already have a separate device that does this so I didn’t personally need it).  If you answer YES, it will attempt to connect to your home network based on the IP and security settings you configured in the code before uploading to the Arduino.  When successful, it will remind you of the IP address to use if you want to see a simple browser based web-page with the temperature information displayed.  For example if you assigned the device an IP address of 192.168.1.50, you can go to another computer on your home network, open a browser and type http://192.168.1.50 and see a built in web-page that displays a simple output of the probes current temperature.  You can hit your refresh button every once in a while to get the latest temperature readings.  Or, if you are away from home, and have an internet enabled phone, or are at work, you can visit your feed at pachube.com in order to see the temperature of the probes through the internet.  This requires setting up an account at pachube.com.  I believe a free account should work just fine for most people.  A free account has a maximum of 5 samples per minute.  This devices only sends 1 sample so it falls easily under the free account.  If you have a paid account, feel free to adjust to sampling timing within the code of the Arduino respectively.

So enough about that, back to business. You will need to download the Arduino programming environment.  I won’t go into the details of all of that.  It’s pretty easy once you go to the Getting Started page from Arduino’s site.  Feel free to do a couple of the sample “sketches” that come with the development environment if you aren’t use to the Arduino.  I used the 0022 version of the environment although I think it will work with earlier versions fine.

Once you have that setup and are talking to the Arduino from your computer, go ahead and download and install the WiFi library from Asynclabs GitHub repository.  You can find it here.  I suggest that you do a sample project (such as the WiServer) first to verify that you can connect to your home network using the Arduno and WiFi shield pair.  And you can find an excellent explanation of the LCD hookup by visiting the ever gracious and wonderful Ladyada’s site here. Last but not least, my code for the Arduino can be downloaded here.

And without a whole bunch of wiring explanation, you can wire up your Arduino and components as shown.  Realize that this drawing doesn’t show the WiFi shield stacked on-top.  You, of course, will need to do that first before you start wiring.  And this drawing shows 4 probes.  My code doesn’t use the 4th one on Analog 3 (ohh yeah… those little grey disc looking thing represent the temperature probes).  You are more than welcome to include it though.  It should be fairly simple to change.

 

I always double, triple, and quadruple check my wiring before I even entertain the idea of plugging my creation in for the first time.  You will need to play around with the placements of the components in the project box.  It might get just a little tight.  I recommend using ribbon cable the best you can, in order to keep the number of individual wires flying all around in there.  And don’t try packaging this thing with all the components dry fitted within a small component board.  That’s fine for testing with, but don’t expect it to work too long because a component will come loose eventually.

Remember to setup an account at Pachube.com.  This will give you your on-line access to view the current temperature.  If you are real handy with coding and understand their API library, you can add the feeds or custom components directly to your web-site. I would be interested in other people’s ideas and custom pachube examples on their own web-site.  I included some simple graphs on my site.  But eventually I’d like to learn the API and put a simple text based version on a page that is formatted for viewing on my mobile phone,  that loads quickly and tells me what I need to know.

Future versions of this device?  I hope to make one or two more versions.  My next version would incorporate Luke Millers relay, and allow me to remotely turn on or off the smoker from the same web-page I use to view the temperature probes.  Sort of an “Emergency Off” or “On” feature, if you will.  My last version would incorporate a device configuration page that allows me to configure the IP, Passcode, and Pachube key from a simple built in web-page, and store those settings within the Arduino’s EEPROM.  That way I don’t need to hook the Arduino up to a computer every time I change settings, etc.  But for now, I think I’m just going to enjoy what I have, and more importantly… go decide what I’m going to smoke for next weekend!

Enjoy!

Hello, world!

Officially… this is post number one on the 10 billionth million superquadrupel thousand blogs that are out there.  The sub-title of my blog site explains my intent well.  But for those that can’t read minds I will do everyone a favor and write it for all to see!  This will be an accumulation of mostly useless stuff, but a collection and self repository for myself.  My ‘memoirs’ for the year… or two, possibly.  Every once in a while I hope you find something interesting or useful.   It seems I finally somewhat understand myself.  I find something usually once every year or so that catches my interest, and I focus my attention on that.  Usually I finish what I have started, and sometimes I don’t.  Hopefully I can at least finish each post that I’ve started so that it seems somewhat coherent to you the reader.  But if I don’t, worry not.  It will be replaced by something better soon enough.  SO please feel free to browse and mingle.  Most importantly with out a doubt you will want to

All things good must come to an end…. again!

Memorial Day has come and gone… snif-snif. A great beautiful weekend! Yeah, it may have rained every day, but that didn’t stop the Fox family from having fun and enjoying all that God has to give.

We had a late celebration for D’s 14th birthday. We partied-hardy at the home. Grams, Gramps, Mom & Dad attended, and Chris and Randy made an appearance as well. Our Saturday evening was spent eating some BBQ’d hamburgers and hot dogs. What better way to spend a memorial day weekend! Everyone left stuffed as usual and I had my normal “bload-and-almost-get-sick-becuase-I’m-so-stuffed” party afterwards.

Sunday my outdoor thermometer read 96 degrees! So we decided to go fishing and get sunburned too! It was a lot of fun. Evan had the catch-of-the-day landing a nice size cat. It put up a little ‘fight’ for him too!

Monday I tried out the Jalapeño recipe that I posted earlier this month. Here are some pictures (as promised) with a condensed recipe.

Get a Jalapeño Corer. (You can find this at Cabellas or on-line)


Stuff some creme cheese into a cake decorator bag. One bar of creme cheese will fill about 12 med to large size Jalapeños.

Cut them tops off.

Fill’er up!

Wrap’em with bacon, stick’em with toothpicks, and lay on a foil sheet.

Grill’em for 30 minutes over indirect heat. Bacon should be crispy. Enjoy.
