Arduinos interface very nicely. In fact, I've tested and am installing an color,
touchscreen engine monitor based on three arduino type microcontrollers. Already
proved out the interface with the GPS (both Aviation and NMEA formats).
I have linear regulators for power. https://recom-power.com/pdf/Innoline/R-78E-1.0.pdf
What I've built is a circuit board with all of my glue logic (linear power supplies,
thermocouple to analog converters, voltage dividers, circuit protection,
drivers for outputs, RS-232 drivers, etc...) on a board that the Arduino (Teensy)
micro-controller board is installed on.
The teensy is easily programmed in C. Working on the air data computer / magnetometer
now. That will feed the data for winds aloft computations to my Avidyne
IFD540.
I've also got a Stratux (home built ADS-B receiver) feeding traffic and weather
via RS232 to my IFD-540 which then shares it to my ipad, etc... That has a boost/buck
converter since the Raspberry Pi needs a bit more power. (2 amps)

Great data points . . .
The first flying uC project I built was
individual CPU, Bus decoders, RAM, ROM,
I/O ports, etc. There were significant
lengths of copper running between chips
to keep everything dancing together. These
were NOT transmission lines terminated
for minimal radiation. Hence, likelihood
of radiation was significant but on the
upside, that uC clocked along at a blazing
4 MHz!
I've not personally taken a uC project
to production so there was never a need to
run through the EMC sniffer lab. All my
stuff was engineering prototype or flight
test hardware. So I'll never know if those
early hammer-n-tongs projects would have
problematic pathways to production.
Today's uC device run MUCH faster but the
family of chips necessary to address
the task are on a single piece of silicon.
Essentially zero bus lengths.
The most energetic violators of RF sanctity
in the cockpit have been display screens of various
types. I recall walking up to a booth at OSH
one year with a VHF Comm transceiver in my
pocket. The starry-eyed entrepreneur was eager
to show me his offering for a little engine
monitor with a 2.5" screen with great color
and brightness. The transceiver in my pocket
went bonkers. Took the antenna of the radio
and probed around the outside of his nicely
crafted enclosure. The greatest radiation
came from the face of the display.
I think the risks for unwanted radiation from
your DIY project is low and probably fixable
if it is discovered. If your project includes
a flat screen display . . . look there first.
Bob . . .
Un impeachable logic: George Carlin asked, "If black boxes
survive crashes, why don't they make the whole airplane
out of that stuff?"

Slight topic hijack, but do you have the details of the RS232 output from the Stratux?
I'd like that input to a GRT Mini display. John

Surprisingly easy!
If you order a CP2102 module off of Amazon
https://www.amazon.com/dp/B01N7RNFRJ/
and follow the instructions here:
http://advanced-flight-systems.com/forum/threads/1489-Stratux-Serial-Output
I did like they did here and connected everything (power and serial) via a DB-9
connector and feed it 12V. I put a boost/buck converter in my enclosure to go
from 12V down to the max recommended for the Pi.
Made my own slim-jim antennas and have had really good luck with the system.
Set your baud rate up appropriately and your receiver to Capstone Wx+Trfc High
Speed and you're set. I forget if I'm running 38,400 or 115200 for the baud rate.
This feeds my IFD540. I do get the "No TIS-B" warning on the IFD, looking into
this now, but I still get good traffic and wx data.

I'm using an Arduino to read the analog 0-5v output from an automotive AFR
monitor (Ballenger AFR500v2) as input to a PID controller, with the output
controlling a linear actuator (fancy name for servo) that pushes or pulls
the mixture knob in my RV7A. I also have a Raspberry Pi-based Stratux in
the plane, and I've never encountered EMI issues. I'd like to add control
of my heater damper because I'm always fiddling with it - always too hot or
too cold.
I'm using these actuators -

Jeff -
>> 1. What is the PID controller running on? (Arduino, uController,???)
- The pid logic is currently running on an ESP32 programmed via
the Arduino IDE. I'm not sure if that will be the final HW platform or not.
I'd like to have WiFi and/or BLE available for future enhancements. The
ESP32 BLE stack consumes almost the entire program space, so I may need to
go with a co-processor to offload the communications or drop the BLE idea.
- I'm using this PID library -
https://github.com/br3ttb/Arduino-PID-Library
>> 2. Where, physically did you place the O2 sensor?
- I'm using the NTK production-grade O2 sensor because it is much
more tolerant of 100LL than the Bosch wideband O2 sensors. There's a good
thread on VAF about this.
- My IO-360 has a 4-into-2 crossover exhaust. You should try to
pick the exhaust pipe connected to your first-to-peak cylinder if you have
that data from EGT monitoring. Mine is placed in the pilot-side exhaust
pipe. I placed the sensor according to the directions in the Ballenger
manual.
https://www.bmotorsports.com/download/products/o2/AFR500v2_Manual.pdf
- There is an article in Kitplanes magazine from March 2019 that
describes an installation similar to mine.
I borrowed the idea for the linear actuator on the mixture knob from this
product: http://flightenhancements.com/auto-lean.html It holds a target
EGT value, where my version holds a target AFR value.

My question, as well. I used silicone bath caulk to reseal baffles to
the heads/cylinders on an RV4 Lyc 5 or 6 years ago, and it was still
holding up well when I sold the plane last year.
A friend on the rotary engine list used it instead of a metal gasket to
seal the exhaust manifold to the block on a racing rotary.

| Subject: | Re: Stratux RS-232 Wx+Trfc Out to various navigators... |
My Stratux has the GPS module installed. Would there be room for the CP2102?
Also, I'm powering the Stratux via the micro USB port. Does the boost/buck converter
replace that by going through the CP2102 or would the micro USB still
work OK without the boost/buck? The Stratux works fine with the iPad via WIFI
but it would be nice to get the information on the GRT Mini display.

Hi Group
Permatex makes a Gray Very High Temp Silicone #27036 good for up to 700F and a
Red Very High Temp Silicone #27038 good for up to 750F. Does anyone have any experience
using these FWF? Thx. Ron P.[/quote]

Hi Group
I didn't answer question, I'm using Silicone to seal holes in Firewall. I'm using
Silicone Grommets with thin SS shields and Aluminium collets and supplementing
with Silicone. I made a huge pass through that after I fill with wires I
will fill with Silicone:

The CP2102 only provides the serial output.
I used the Boost Buck converter, a separate module that I installed in the Box,
to power the Raspberry Pi. I wired it directly to the Raspberry Pi, not through
the micro USB port. Mine is installed in the airplane. Wired to a breaker and
to the IFD.
I would anticipate that the MicroUSB may provide enough power assuming your runs
are short and your supply is running at the upper end of the pi voltage range.
I prefer a more permanent connection than the micro USB. If you're using a
USB GPS, you'll need to make sure that you can squeeze all four USB devices in
the 4 USB ports, or work an alternate option. You can try short USB extension
cables as well. They make them with 90-degree connectors which may help.

Hi Charlie
Thank you for reply. Can you recommend a specific caulk and perhaps where to buy
it? Thx. Ron P.
