That's my "good" e-mail address.
This idea blatantly stolen from my brother's web site.
You have to type in the e-mail address, but no junkmail-bot can reasonably harvest it automatically.
Before you mail me, read this:
The documentation about my old hobby electronic projects is all there is. I have been asked many times whether I would just quickly supply complete schematics, better documentation, complete parts list with sources, custom adaptations of designs etc. People have blatantly asked me to do their college/university projects for them. Except in rare cases, I don't even reply to such emails.
People often ask whether they can use pictures or video from this site in their projects. I usually give permission, supply higher resolution images, and only ask that I get a web link (for web stuff) or physical copy (for postcard / poster / book / magazine / CD type projects).
