Bill Bowden’s Circuits is one of the oldest Web Reference, it was hosted by CompuServe homepages and later moved to his own domain website.
A small collection of electronic circuits for the hobbyist or student. Site includes over 100 circuit diagrams, links to related sites, commercial kits and projects, newsgroups and educational areas.
Most of the circuits can be built with common components available from Radio Shack or salvaged from scrap electronic equipment…….

I saw some photos of products, some images were good, some focus lost, few of them dim. Even i had lot of trouble with photographing objects. So here is a collection of resources to improve this skill of Indoor Macro photography.
Macro photography is extreme close-up photography, usually of very small subjects and living organisms like insects. Electronic Product Photography is a Branch of commercial photography and similar in most respects to food photography.
Apart from technical photography and film-based processes, where the size of the image on the negative or image sensor is the subject of discussion, the finished print or on-screen image more commonly lends a photograph its macro status.
“Macro” lenses specifically designed for close-up work, with a long barrel for close focusing and optimized for high reproduction ratios, are one of the most common tools for macro photography. (Unlike most other lens makers,
