I really like the idea of an electronics subsection. Maybe call it "Electronics and Programming" If there is enough interest from the community, I'll make it happen  |

(Seriously, is it that hard to make a forum? (I dunno, I don't do this stuff). If it isn't much work, then what's the harm if no one posts in it?)

Its pretty easy, takes less than a minute to add. We have to be careful not to overcrowd the forum with categories and sections because it can become overwhelming to look at. So the rule of thumb is: if people aren't going to be regularly contributing to it, the section needs to be removed or merged with another section.

I agree that overcrowding is to be avoided--but you're still some distance from becoming CNCZone or RCGroups. I notice that "Other" has only a couple of threads--if you're concerned about forum growth, maybe change its definition from "Other types of propulsion" to "Other turbine/rocket related stuff" or something and we could put electronics/programming threads there.
I do have a feeling that the electronics/programming/whatever should be directly relevant to the main thrust of this forum: namely turbines/rockets--there are plenty of other places for folks to discuss electronics-in-general or programming-in-general.
Edit: I just read through the rest of this board and only noticed half-a-dozen or so electronics related threads--mostly just specific questions rather than builds, so maybe there wouldn't be enough interest after all.....

In regards to the first comment posted on this thread, I am making an ECU/ECM/FADEC using an arduino also! I am interested in seeing your progress

There are many microcontrollers and computer aided control systems feasible to make. Since it's a rather rare subject by comparison, no need for several forums for each platform, chip, or idea. |

Wow, this is the first I've heard of it. If anyone gets their hands on one, let me know how you like it. I'm hesitant to trust reviews on MFG/retail sites these days. |

The way I understand the raspberry/banana pi vs arduino, is that the raspberry pi and variants are designed to be used more for user interface and processing/computing and digital control of digital things, where as the arduino is made more for basic computations and controlling physical things with digital means. Someone correct me if I am wrong, but that is why I went with an arduino for my build

Has any one pursued the use of the Raspberry Pi 2 for a FADEC basis?
I also agree that we should have a section that is totally dedicated to the FADEC,electronics,etc,of getting our turbines up and running safely,weather they be home built or we have a commercial turbine that might be missing some of its critical start and run systems.I really dont want to run around cracking valves,hoping my fuel pressure,etc,etc,etc,even with guages and what not to look at and calculate where I need to add fuel or what not.I guess im rambling but we really need all the electronic threads in one place so we dont have to search all threads to get any kind of ideas on how we should proceed safely.

I havent made one but it honestly should be a lot easier than Arduino. My experiences with creating artificially multithreaded scripts to control asynchronous process have been nothing short of a nightmare with Arduinos.

What is the difference between an arduino system and a raspberry system they both use dos commands. Is one easier to program than the other?

One is not necessarily easier than the other in my opinion. Arduino is good for learning basic logic controller stuff. You can buy them at RadioShack, hobby shops and some book stores, so if you burn one out, a replacement is right down the street. They are best suited for less complex projects, but with a bit of work, you can make more complicated things work and learn a lot in the process. I did some lighting effects on Chris's bike, which was complicated by the need for a thread to be listening for button presses, while another thread follows very time sensitive lighting sequences. The visuals look nice, but the code got really ugly. Here I am using an Arduino to drive something like 200 individually addressable Adafruit Neopixels. The logic controller also listens to 4 button states: Pattern Forward, Pattern Backward, Smoke(AB FUEL), and Hot Streak. The raspberry pi is capable of actual multithreading. This would allow you to do the same thing by essentially keeping one thread dedicated to a button event listener, and another thread doing your basic logic and managing output.

Somebody please do it. I am having enough trouble with 1950's turbine technology let alone real magic like microcontrollers.

Here is a pic of the basic thermocouple/pressure transducer "boost" monitor ecu I made for my turboshaft in progress. It is based around an Arduino Mega and I got the sensors off of ebay, and the thermocouple breakout board from adafruit.  i |
