Not Just Manuals (for not just programmables)
Please note: my uplink (i.e., from me to you) bandwidth is limited. Only download documents that you actually need. My Web site is not going to go away... if you need something else tomorrow, it'll be here. If you ignore my warning and start downloading large PDF files in bulk, don't be surprised if suddenly, you find yourself unable to access this Web site.

Technical Notes
- First, a disclaimer: beware of programmers who carry screwdrivers. I am a software guy. Although I know how to handle a soldering iron and have some burn marks on my hands to prove that I am no novice, my expertise lies mainly in programming computers, not building or fixing them. Take this into account when you read the articles below.
