I've spent the better part of the last 3 years playing with home built control systems. The one thing I've found that seems to always get overlooked is the efficiency of the smoker. I've also found that many people who want a control system, unknown to them, want them because their smokers are...

Assuming Guru uses Thermocouples for their heat sensor, it could be 2 (or more) issues: 1.) Thermocouple uses cold joint compensation to calculate the final temp. If that cold joint (probably on the guru) is getting hot or overly cold, it can effect the result. Possibly move your guru or wrap...

I use Phidgets hardware (www.phidgets.com) which are a bit more expensive than the Arduino's Bob is working with. But, they can be programmed using VB and VB.Net (and VBS for that matter) which is much easier on lazy coders like myself. I use their servo and motor controllers to operate fans...

Not to over simplify what you are trying to accomplish, and this is by means not the most efficient way to burn burn fuel, but have you explored the possibility of just using a thermostat style of control. Set a high and low. When the high is hit, shut off the fan. When the low is hit, turn...

I totally gave up on trying to calibrate them based off of the non-linear coefficients. Since I already required the horsepower of a computer to run the program, I just create a xref database record for each probe. I have a program that captures the probe reading (collecting voltage drop) and...

I've enjoyed your all's conversation; this is neat stuff. I have been working on a DIY controller for a couple of years that uses either a fan or a servo damper. Mine uses a PID loop, so it doesn't suffer from the oscillation that you guys are talking about. Unfortunately, mine requires a...

About 2 years ago I did some extensive research on this topic as I wanted to build one myself. These guys have been around a while. I like what they are doing, but I'm too lazy go as far as they did. I went the easy way out on mine and used USB based devices that are already built. I wrote a...
