[posted] Air Data Computer

[JLJ]

Basic Air Data is an Open and Free project.

We have posted here a project for a versatile DIY air data computer. (some pictures here). Project is always under development. The Teensy 3.6 board was the natural choice for us, plenty of I/O and elaboration power.
You find in this link applications for an ADC. For example you can use the ADC with a DIY Pitot Probe to measure airspeed. (Wind tunnel tested).

The ADC can exchange data messages with an Android Device, see Bluetooh Helper lib and message standard.

My job back in college did air flow testing and this brings back some memories. Are the 2 air input ports for total and static pressure coming from a pitot tube? I like all the out of the box stuff you have--even CAD drawings. What CAD software did you use?

[JLJ]

Great to hear that you worked with Pitots. College ? College was a great time! You are right about pneumatic connection. With the ADC you can use a generic Pitot-Static probe or build your probe. We've tested this 8 mm probe. The project is for DIYers, so all the past contributors tried to use the most excellent, free, and readily available software. In practical terms, we have a mix of different software formats. We have Draftsight, Inventor, Freecad, Sketchup and even Blender format files (sorry if I miss someone, you can download all this software from their producer's homepages); as a general rule, we tried to produce STEP and STL files too. We have tried different solutions, but we have not a champion. Any advice is welcome.

Update:
We've been told that is not straightforward nor comfortable to source all the components for the Asgard ADC. In a collaborative effort, we are trying to find a way to centralize some operations. Like PCB printing and population. This proposal is not commercial. It is strictly Do-It-Yourself oriented.

With a certain number of participants, we probably can reach out to many users across the world.


We've some feedback from the ADC users, look what a nice RC F104!

Your feedback is warmly welcome!
