Test, test always be up-to-date
For the enclosure I go for the Hammond 1551KTBU. It’s not that expensive and looking cool (blue). And it fits all the hardware. There are only a few SMD components so easy to solder.
Suggested hardware: small microcontroller powered by 2 AA batteries controlling a WiFly module. IP and/or SSID setting by 2 leds and a push button. Did I miss something?
Well, click the hardware menu item for an initial schematic.
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 !
