This garden railroad modeler built a morse code signaling beacon for his layout driven by a Picaxe 08M. He shows you how to design it to either flash or sound out your desired messages. The builder also updated he article a few years back with a more hardware-friendly Microchip 16F684 PIC processor.

i just can’t figure out why the Picaxe chips arent more popular than they are. i mean, you rarely see them in projects on this and other sites. they are so simple to program, and simple to interface hardware with, and super cheap. theres gotta be a drawback i have not seen or experienced….

I made one a few years ago, that keyed a home brew HF transmitter. Pic’s are great fun.
