So I've just finished my latest project - an FPGA based FM transmitter that beeps out SOS in Morse code. All you need is a wire and 60 lines of VHDL!
I was musing over it all day and decided to give it a try.
There I was feeling extra clever at how well it works, and upload the a video of it in operation to Youtube. As soon as it finished it recommends that I might want to watch another video - it is somebody transmitting music on FM using only an FPGA. I don't feel so clever now!
