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 4 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]
