Status: On hold.

Update from April 2017:

I have achieved some promising results with WiFi, however I’ve noticed that using iPad as a primary display with ADAHRS connected via WiFi is not very reliable combination. Maybe it is my implementation. Anyway, I’m changing to CAN Bus as a primary mode of communication between different modules of my avionics. Maybe I’ll get back to WiFi as a add-on to CAN-Bus.

So, for now, the WiFi development is on hold.


The idea is to build a remote ADAHRS module with iOS, Android or Windows tablet as a Display.
This idea is not revolutionary new. There are few products on the market

Lets see if I can put together something similar for under $300 USD.

At this stage I’m prototyping the device based on ESP8266 with Arduino IDE.

The general idea is to send raw data from the ADAHRS to a tablet via WiFi using websockets and JSON (or XML).

So far the results are very promising.

Stay tuned!

    I’m very interested on this WiFi ADAHRS project. How is it going so far?? I would like to build it for my own ultralight aircraft. When do you think it will be done? I hope to hear from you soon!!!

    Best regards,

    I would like to build my own. I almost ordered the Talos, but when they wanted over thirty dollars for shipping from Florida, I canceled the order. Principal of the thing. Be very interested in what you have to offer.

    What I really want is the EMS WIFI to my Samsung tablet. Are you working on this (WIFI for the EMS)? I know you are working on the EMS and I would like all the information you have so far. I realize it is a work in progress but I would like to start studying on it. It’s a hobby project and I will definitely use it in the Ercoupe when finished.

    Many thanks,

      Hi Keith,
      I plan to use WiFi as a secondary information channel, basically re-translating the data from CAN Bus through Web Sockets via WiFi. This way I achieve reliability of the primary instruments and have all the information in a “pretty” form on mobile devices. I didnt progress too far in that area yet, but it is definitely in the pipeline.

    Try using micro python it simplifies the tool chain and gives you access to a good OO lanuage.

      I actually tried micropython. It is great platform! Petty there are not many libraries for it. I’m thinking of using python for CAN-to-WiFi interface.
