What are you looking for (generally)? I sense you are something of a
newbie in electronics?
I have a few surplus electronic sites I like, neat stuff and some of
it cheaply priced. All Electronics, Marlin P Jones, bgmicro,
electronic goldmine, and not strictly electronics - american science
Can or do you program? There are several neat single board computers,
or integrated circuit controllers on the market that can do some
pretty interesting things, and it is possible to achieve in software
what would take an enormous amount of hardware if you were to do the
same thing with logic or linear IC's
Some idea of your interests would aid in recommendations.
