in reply to homemade data acquisition

I was wondering if anyone has had any luck with home-grown data acquisition systems and fetching/analyzing w/ perl. Namely, I was looking for some schematics for a suitable ADC chip (TI, National Semi, etc..) that have a real shot at hooking up and working via USB, RS-232 or Centronics and can be accessed w/ perl.

A friend whipped up something cool using a Basic Stamp board to run to some data acquisition, which he then processes and charts using Perl scripts. The Basic Stamp has an on-board processor, and speaks a serial protocol over RS-232, so it's pretty easy to drive from Perl. Some configurations have on-board wire-wrap space.

Here is another project that uses the Basic Stamp to collect data for later processing via Perl.
