Hey Vern,

I had a similar idea but no time to get to it yet. Yours cool though.

Great project!
You really need to go check out M5Stack.com. They make the hardware. I've used the ESP devices in several designs. The ESP32 device used in the M5stack is impressive. That's the CPU I use in my proprietary designs.

They are still finding their footing in terms of product quality and support, but I am looking at modifying the mechanicals and electronics. Did you know that it's designed to plug into Lego? The mind boggles.

Based on feedback received (thanks!), I've made some modifications to the display. I also widgetized the AOA and Slip indicator so I can easily scale them and place anywhere on the screen. Oh, I also discovered that the M5Stack supports memory Sprites, so I can eliminate screen flicker cause by redraws of information on the screen.

It's easy to reconfigure display modes, some are illustrated below.

If the weather clears today, I will perform a flight test!

Default Purchase?

Vern. I like this. Can I buy one? Or the parts? I like that you have a number, I assume angle on the AOA. Nice work. It’s slick.

Nice work, and those are slick little units... I may have to order one or two. Hadn't seen them before.

I don't sell anything, but I will posting the software once testing is completed. Some additional hardware design is required as well to allow for connection to ship's power and the data link. I will post this design as well. You are correct that I am displaying the AOA number. This will become important later on when I have to input calibration data from my airplane. During my flight testing, I have found that the intersection of the horizontal green bars and the yellow chevron was at 50-52% and that the EFIS display was slightly different than mine.

Caveat: these module come from China and need tender loving care. I have two and both have failed in different ways. One was the battery module (not needed) and the other fails to program (probably due to my abuse). I would recommend not purchasing the 'Fire' version, just the basic grey block.

I am traveling for the next month, so only sporadic postings will be made, so please give me some time. Here's a teaser from flight testing. Everything went well:
