Welcome to Craig Starks DIY Audio pages (old copy)
This is a copy of Craig Starks DIY Audio pages extracted from the
Web Archive as of 23rd October 1999.
All text found below the twin line is written by Craig Stark.
3/11/99: It's been several months since again the last update. I know many
of you have sent me links to add & I appologize for the delay. Unfortunately,
maintaining the page is low-down on an increasingly long to-do list. In
fact, I have thought of pulling the plug on the page a number of times, and
were it not for the amount of positive feedback I've gotten (and the fact
that I just found out we're at 400 hits/day) I might have dropped it instead
of putting in this update. Anyway, I've weeded out some old links and
will put in a number of new ones in the next few days. Enjoy!
As you might have guessed from the title, this page is meant to be a
reference for the DIY audio community. Currently, it consists of a large
number of useful links that I've compiled as well as a section dedicated to project materials you can download.
If you've got links or projects to contribute, or if you have some feedback
for me, please e-mail me and
let me know so the page can grow and become more useful. And now, on with
