- Serial Logic Analyzer (20050325)

- A Zephyr-Like AOL Instant Messenger client (20041018)

- Simple C/Unix Memory Problem Debugging (20040602)
- A simple tutorial on how to recognize some common memory management errors for C and C++ programmers on Unix. After showing these simple cases to a few people at work, I thought I'd write them up and share them with the rest of the world as well. This is for people who took computer science classes which didn't touch on ``applied'' things like debugging.
- LED Flashlight Modification (20040124)
- A modification of a 2-AA Sears flashlight to take 7 white LEDs, using three 2/3AA NiMH batteries. The Sears flashlight is better than a Mag-Lite for this because it has a separate switch instead of using the reflector.

- Linux Utilities for MeTex DSO (20020515)

- Largan L-Mini 350 Interface (20020304)
- Steve O'Conner's programs didn't work for me (kept generating timeout errors), so I made my own. I'm not saying it's any less klugy, but it does happen to work for me. It's written in Perl, and supports everything but the Thumbnails (because I was having a hard time figuring out the thumbnail format, and the Largan-supplied converter code didn't seem to work). UPDATE: Thumbnails are now working.
- This is Linux. Isn't it awful? Please go home now. (20020128)

- Debian GhostScript package with Samsumg GDI driver (obsolete) (20010101)
- The Samsung ML-4500 family of printers require specialized drivers, and provide a hacked GhostScript which includes them. However, they provide only Red Hat packages. I extracted the source patches which provide the GDI driver from their RPM distribution, applied them to the Debian package, and built it. This is a quick hack without documentation.
- pmh (dead) (20001011)
- pmh is a rewrite of mh in Perl. It's not usable, and isn't being worked on anymore.
