I'm just a hacker at heart... it's the way God wired my brain.😃

I made the 2600 whistle out of a short piece of copper pipe, some solder, and a screw to fine-tune the frequency. I made the other tone whistles out of sections of a plastic toy pan-pipe. I can still see them in my mind's eye; they could even be lurking in the attic somewhere?🤔🧐😜
