I want to start a thread on exploring the use of microcontrollers onboard RC airplanes. This will likely be a long term project and I won't really get into it until after FTFC23 is over. I know several other forum members have experience in this area. Maybe we can trade notes and all learn something. Anyone's ideas, suggestions or experience in this area is welcome. I'm not wanting turnkey solutions that tend to cost north of $20 US. I prefer to get my hands dirty to keep learning. I'm talking about home-brewing a whole system for about $10 US. I would like to get real-time data for gauges and such as well as data collection for black-box post mortem analysis . A little soldering, a little programming and Voilà! I want start with just the readings side and include:
- LiPo voltage so I can more intelligently know when its time to land. From EDF jets that guzzle energy to sailplanes that sip it. Using a timer is just not cutting it.
- Current draw
- Motor temperature - I've burned one up trying to fly upwind back to the landing site - https://forum.flitetest.com/index.php?threads/inqd-turbo-storch.71382/page-4#post-738136
- ESC temperature - Ditto - https://forum.flitetest.com/index.php?threads/what-did-you-crash-today.23426/page-85#post-739293
- Air speed
- Propeller rpm
