In college we had an I2C to ethernet adapter on our drone testbed that caused all sorts of RF interference for us. We eventually wrapped the whole fuselage in a farraday cage so that the datalink and flight controls wouldn't be overwhelmed. It was responsible for transmitting data at a 1 Hz rate, and we could visualize the interference on a spectrometer over a broad range of Rf at exactly 1 Hz.

Anyway, we totally could have made a transmitter out of that thing.

I thought i2c slowest clock was 100kb/s, how did this end up in a 1Hz rate?

The microcontroller gathered data and pushed it out the I2C interface once every second.
