This morning I was lazily browsing Reddit when I came across a project by the Imperial College Robotics Society in the UK. It’s code and instructions for using the Raspberry Pi as a low-power mono FM transmitter. When I saw how easy it looked to do, I ran over to my Pi, downloaded the code, and got it running within a matter of minutes (see video above).
One of the best parts about this project is that you don’t need much hardware besides the Pi itself. Just connect a 20cm piece of wire to GPIO pin 40 to act as the antenna and then you’re all set. Click on over to their wiki if you’re interested in trying it yourself and how it works. [via Reddit]
