Wikipedia has an excellent article on breadboards. Just search for the
word breadboard. These are all solderles breadboards. There are many
links to related subjects.
On google, a search for "solderless breadboards" brings up links to
various manufacturers.
The breadboards themselves are relatively inexpensive. Getting enough
components to build actual circuits could cost a lot more. When I was a
kid more than fifty years ago I obtained parts by taking apart AM
radios. That doesn't seem to be very practical with modern equipment.
I am interested principally in prototyping some audio circuits. A
microcontroller wiol also be needed.
Suggestions from people who have experience along these lines will be
much appreiated.
Thanks,
John
