Char Buss and Tom Schum welcome you to our website!

Jump to Sigma Photo USA

This page contains JPG HD photos (1920x1080x3) from various cameras.
See bottom of this page for electronics/free-energy articles.
See "HD Tech" page for detailed technical discussions.
See "Photos Archive" page for older non-HD photos.
See "OLPC" page (One Laptop Per Child) for calculator project (old).
The ugly secret of photo websites:
   They sell the photos, so the view you can get for free is low-resolution.  It won't look good as a "wallpaper" or background image on your desktop.
