Ive had a blast playing around with the PICAXE. Its super easy to use and program, but you loose a lot of speed. Still, I have manged to make a few things music related.

Tonight I made..well...a wardialer. I had a NTE1690 that I found in my dad's garage (in the original Radio Shack packaging) that was begging to be used somehow.

This is what I ended up with.

Posted Image, might have been reduced in size. Click Image to view fullscreen.

This is the simple version. The next one will use an external clock so I can mess with it (LFO, vactrol, whatever) and might have a filter or distortion or something.

Thoughts?
