Welcome aboard; good to see you here. Please open up a thread or two showing what you've been doing; I'll bet quite a few folks here will find your stuff interesting & useful.

Here's a teaser post of the huVVer-AVI flight instrument... open source library provides six selectable instruments. All user configurable and capable of using serial RS-232 inputs or (Dynon only), WiFi streaming.
Runs on the commercially available M5Stack devices, or the fully-productized huVVer-AVI devices for aircraft use. The huVVer-AVI devices have an aviation-grade power supply, a larger daylight-readable screen, RS-232, CAN, sensor inputs, relay driver outputs and stereo audio outputs. Available off the shelf from MakerPlane. Software available from huVVer.tech.
During development, I decided that a general purpose library was required for drawing instruments of all sorts, hence the underlying GaugeWidgets library. The flight instruments are just one example in the library.
Future releases may include a suite of engine instruments, which are already coded but there are few 'standard' displays due to the multitude of engine types out there, plus varying personal tastes.

For those of you who attended OshKosh this year (2021) here is the energy display used for the Grand Champion Founder's Innovation Award prize-winning OnSpeed system. I am a member of the team, and developed this energy display to augment the audio tone system. Shown here on the M5Stack.
Finally, here's a teaser from my ongoing engine instrument development:
