I finished up my first version of the 18F2620 cheap logic analyzer (about
$10) which is capable of taking 3936 samples at a 5M sample/second rate
(200ns/sample).  You can find the new project here:

I added a voltmeter mode where the 5 analog inputs of the PIC are sampled
and displayed on the screen.  I also implemented run length encoding for
transferring the samples in order to get the update rate a bit faster over
the ~10Kbyte/sec serial port.  The PC side software can cleanly update the
PIC firmware so as new versions are available, the changes will not require
pulling the part off the board.

I also created a bootloader for some of the 18F devices that can found on
that page as well.

Let me know if you find problems.
