Ball balance beam video
This is a servo mechanism toy I've been playing with. Ultimately, it will be able to put the ball to any desired position on the beam and keep it there, as well as track various input waveforms. It demonstrates how a mechanically unstable system can be stabalized using just electronics. That's Analog (for those too young to remember it) using PID control. I update this from time to time, and will make it a full web page when done. It's probably best to download the video file. Video views well with VLC Media Player.

How to protect an Arduino (AtMega processor) while using an external Aref input voltage, and still maintain precision.
How to modify an electronic rain gauge to deliver a minimum pulse width to the mechanical counter, so that it never misses a pulse.
For those who couldn't be there, a link to pictures of the memorial paddle-out for my good friend Buzz Sutphin, who succumbed to brain cancer at much too early of an age.
This was an interesting restoration project.
Documentation of a mess.
Other people's stuff (alphabetically):
Website on all things vacuum, and related experimental physics.
A good open source hardware forum; some software. Worth a periodic visit.
A good place to get electronic parts. Easy to order from, good stock.
Another good comic. When this starts to describe where you work, take it as a sign that it's time to move on...
The world of 'empty state' devices, and things that make sparks.
Web security stuff from a guy who writes windows utilites in assembly language. Be sure to see "password haystacks", under 'services'. Also, buy a copy of his HD maintenance utility, "Spinrite". It's saved my butt many times!
Website on all things experimental - must read daily. "Hack a Day serves up fresh hacks each day, every day from around the web as well as hacking related news."
On the TEM wave and classical electromagnetism - why everything you know may be wrong. Stuff that can make your brain hurt. [Website layout is a bit random - you have to dig a little for the good stuff.]
Facinating blog on just about everything electronic, neon, energy related, computing, etc., by a guy who knows what he's talking about.
Another good place to get electronic parts. Easy to order from, good stock.
Build something. Learn something.
Bill Louis's website. Bill is a very talented product designer whom I've worked with quite a bit on various projects, and who I highly recommend.
"A webcomic of romance, sarcasm, math, and language". My favorite on-line comic. Not for liberal-arts majors.
