Reading Wireless Air Transmitter using Arduino

[Timmyjane]

That's not really accurate. The original project did not die; it ended successfully. The goal of decoding the signal was achieved; see posts 131 and 163. Some folks wanted to go beyond the original goal and try and build some kind of receiver/transmitter and that progress has indeed been slow. Hey, it took a year and a half just to work out the decoding!

Working out the decoding was super impressive. I did read the whole thread and was blown away. It’s amazing what different people know. I was disappointed that there was no DIY transmitter built.

It’s sound. I had no idea either. Pretty wild stuff.

The MH8A is RF at 38kHz, not sound. The Garmin transmitter uses sound.

@rg422 has documented the decoding project on GitHub at

What it needs is an Arduino buff with some time to jump on it.
