Default More Arduino avionics

It is great to see experimental aviation going beyond rivets!

Here is the stuff I've been working on if anyone interested

Arduino based EFIS: http://experimentalavionics.com/efis-19264-ver-1-2/

Some video here: https://youtu.be/emqc_vi7-Rg

Cheers,
Oleg

I am by no means a software guy, and it's been a few years since I last messed very much with hardware. Seems these microcontrollers have really leapt forward in both their capacities and their reliability.

I'm running an AF2500 engine monitor and would really like to be able to capture its data on an SD card. Since I'm hoping for first engine run sometime soon (soon, in aviation terms, means this year, maybe... LoL), I'd like to be able to capture data from first engine start, but don't want the labor of messing with product development to get in the way of the labor needed to get ready for that first engine start.

Verns "packaged" product looks like a good idea. Now if only I could figure out how to use pre-developed code (like Brantel's serial data logger code) to load on the board.

Or maybe there is already a pre-packaged data logger available that would suit this purpose?

Oleg,

Love it, is there anyway to wifi to the display screen. Thinking of the new iLevel BOM system where all the sensors etc are in a wing mounted unit and info is wifi'd to the in cabin display

Default Falcon-AVR group buy

I'm organizing an order for the Falcon-AVR final version pcbs. These are 4-layer boards and I'd like to get 20 boards ordered and in the hands of Arduino fans within a month. http://vx-aviation.com/documents/Falcon-AVR/


I already have three people signed up for blank boards. If anyone else is interested, please send me a PM.

Thanks, Vern

So true. Some time ago, I designed a logic circuit for a custom motorcycle instrument panel. It was flakey to the point of uselessness. Finally called my dad for help because he was skilled in the art. Turned out all my logic was correct but I did not have all the "protections" in place to make it a robust device. It was a learning experience. Success happened after his help.

Nice work BTW.

Very early in my career, I worked for a telecom company and we had to deal with residual lightning strikes, 600 V power line crossings and ESD.

Here is a design I did in 1982. All of the stuff in the foreground are environmental protection. I did the all of the card design, thick film hybrid design, some of the chip design and we used new fangled devices call PALs (ref 'Soul of a New Machine'). We were the largest consumer of surface mount devices in North America.


Yup, 1982... sigh. BTW it's an 8-channel LS/GS trunk interface card... you can still buy them today.

Default Pixel C tablet with Garmin Pilot

Has anyone used a Pixel C tablet with Garmin Pilot.

I would like to use it for the right screen and the size is perfect.

Has anyone used this in a their aircraft.

A few folks have asked me about component costs for the Falcon-AVR.
Here's a breakdown of the options:

28 Volt, field configuration (includes case, primary input protection, etc.) $68
14 Volt, field configuration (includes case, primary input protection, etc.) $57
28 Volt, lab configuration (no case, only secondary input protection) $52
14 Volt, lab configuration (no case, only secondary input protection) $40

I would recommend starting with the lab configurations, then adding components as required by the application to get to a customized field configuration.

The costs were derived from Digikey's low volume pricing. Careful shoppers and those who buy in quantities can probably reduce the cost by 50%.

I'm still trying to get a group together to share the cost of a pcb order. PM me if interested.

Default Falcon-AVR demo program

Here's an example of a simple C program (Arduino sketch) that shows how easy it is to process Dynon or Garmin serial information using the Falcon-AVR here.

This program displays:
HDG
IAS
ALT
AOA

on a 20 x 4 LCD screen as a 'backseat' display. The ALT is corrected altitude using the barometric pressure setting.

It took about an hour to write, which is pretty good because 'C' is relatively new to me (... I remember FORTRAN...)! I cut it down from a 1600 line program (auto-trim controller) just to demonstrate the function.

I have a graphics display module that would be very cool to use for virtual instruments, but that's a different project!
