At first, a proof-of-concept

Hi all, this blog will be about unlocking all the telemetry data from Hitec RC systems and display them on whatever device. My goal is to produce a plug and play system that works out-of-the-box. And for all geeks like me: all hard- and software will be open source and can be modified to whatever needs.

Imagine what you can do with this:

  • Display all telemetry data real time on your tablet, laptop or PC.
  • Combine this with real time GPS data displayed in e.g. Google Earth
  • Log all the data for after-flight analyses
  • Share and compare your flight with friends
  • Great for competitions

In a few words let me explain how it works. Hitecs 2.4 GHz TX module (called Spectra) contains a so-called ‘data port’ connector. Besides firmware updates the ‘data-port’ also holds ‘telemetry data’ like RX voltage and all the other sensor info if a sensor station is connected.

I’ve created a little piece of hardware that connects to the data port, the Spectra things it’s a HP22 and spits out all telemetry data. Than my little piece of hardware routes all data to a $30 WiFi module. Your tablet, laptop or connects to the WiFi module and voila, with the proper application all data is available.

The project is not finished but here’s my proof-of-concept:

Have a nice day !
