[sdiy] Random Tone Generator redux

[Ian Smith]

Hey all,
A while back I posted something about working on a random tone generator, begging for a link to the hand drawn schematics, and saying that I was working on digitizing them to make them a bit easier to read.
Well, time passes, I lost the link... again... but I have a print out sitting on my desk, and I've put a highly modified version into Eagle to brush up on my PCB skills.
I haven't actually tested the circuit yet (just not enough time between classes) but it's completely based on CMOS chips at the moment.
I'd love to get someone's opinion on the thing so far, but I'm not quite sure how to post documents to the list.
The other thing I'm wondering is, if this were to be a module, what would you want it to have in addition to the tone output?
Thanks for your time,
-Ian
