The article is great. He just forgot to explain how and why (84 Mhz microcontroller for a FM radio ? ) he did it. /s

Another day, another hack, is the hackaday way.

That in fact is quite overkill; probably it was what he had at hand. That FM chip can be controlled by any uC capable of bitbanging i2c, so pretty much every cheap one including small ATTiny uCs that cost one tenth of the Arduino Due.
