I Designed and Built My Own Angle of Attack Indicator!

I put some of my engineering skills to work to design and build my own 3D printed Angle of Attack Sensor and accompanying Indicator that runs as an app on an Android device!
This is the first video in a series where I will discuss how to build your own Angle of Attack Sensor and Indicator (and what exactly Angle of Attack is in terms of aviation).
==============================
Disclaimer: If you elect to build one of these devices, you do so at your own risk. This device is not certified and it is not for use as a primary instrument for flight. If built and calibrated correctly, it can add situational awareness to the cockpit (similar to an ADS-B receiver), but should not be your primary source of information regarding a stall. I don't recommend its use in certified aircraft.
You, as pilot in command, accept responsibility for the safe outcome of every flight.

Just thought about how to make my own diy AoA sensor and found your video. Thank you for making this video and sharing details, especially for telling about rotary magnetic encoders, I didn't knew about them and planned to use two Hall sensors instead. One small suggestion -- seems like sensor measurements jitters so the indicator display changes frequently which may be distracting. Maybe using some simple smoothing algorithms like moivng average will help? Sure it adds some delay but angle of attack does not (normally) change drastically in fraction of a second.

No problem. Glad someone else is finding it useful. I originally designed the sensor to measure both pitch and yaw (e.g. a second wind vane and rotary encoder that rotates on a vertical axis) so you could potentially measure how close you are to a spin as well. At that point I was doing some smoothing on the Arduino. I think I was taking a reading from each rotary encoder every 50ms and then sending an average every 200ms or something like that. But after learning a little more about how Bluetooth LE subscriptions work, I found it was more efficient to just pass data when the reading changes, which might be almost immediate or not. Which would save power - for example, say you land somewhere and forget to power down the sensor - while it's sitting on the ramp it would only use power to send a BLE message when the reading changes rather than every Nth millisecond. As I'm thinking about it, it probably makes more sense to do the averaging on the Android device rather than on the Arduino within the sensor. Anyway, you've made a great observation and suggestion. Thanks!

Hi Dan …this is brilliant device, can you help build one unit for me ? I fly am experimental plane and would love to install this device ..if able. Kindly let me know

I have made the project open source. You can find details on my website and build your own: www.danderflieger.com I don't want to make this a business. My hope is that people can take what I've started and build it for their own use.

Nice! Why not make it available to other pilots?

Hi Job. Thanks for watching! It actually IS available to other pilots. It's all open source so people can build their own. This is the first video in a playlist that shows how to assemble the parts yourself. The only thing I haven't posted yet is the 3D models because I haven't had an opportunity to test them enough. But you can find a list of parts, wiring diagrams, code for the Arduino and the Android side as well. Here's a link to a page on my website for more info: www.danderflieger.com/my-angle-of-attack-sensor And here's a link to the KZfaq playlist: kzfaq.info/sun/PLxrmWNrs-eflDOwBQS-R1qsKZQ1rDAkZt
