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) (https://www.basicairdata.eu/projects/airdatacomputer/asgard-adc/adc-asgard-pictures/). 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 (https://www.basicairdata.eu/projects/air-data-systems/air-data-systems-applications/). For example you can use the ADC with a DIY Pitot Probe to measure airspeed. (Wind tunnel (https://www.basicairdata.eu/blog/2017/03/24/8-mm-basic-air-data-probe-tested-in-wind-tunnel/) tested).

The ADC can exchange data messages with an Android Device, see Bluetooh Helper lib (https://github.com/BasicAirData/BluetoothHelper) 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?

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 (https://www.basicairdata.eu/knowledge-center/construction/flanged-pitot/). 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 (https://github.com/BasicAirData/8mmPitot-StaticProbe/tree/master/Drawings/FREECAD%2BSTL%2BSTEP/AssemblyPitot-StaticOnly), 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!
