    Doing some lessons and experiments with students on an Arduino Uno. We are breadboarding some simple circuits, attempting to teach some digital logic.

    Can any of the mail order companies sell me a simple assortment (grab bag) of resistors and capacitors? I've looked and Mauser and DigiKey and can find nothing. All pointers or 'Key-words to use' would be appreciated.

    Thanks, Ivan Vegvary
  2. Tell them to start looking for electronic junk tossed out. More recent
    stuff has less to offer, but there are still lots of VCRs around taht can
    supply a nice spread of small signal transistors, capacitors and
    resistors, plus switches on the front panel and LEDs. The motors may be
    useful for something.

    The same with cassette decks that are getting tossed, analog meters or
    "LED level meters" (often a daugther board so it can be kept intact),
    motors, low power AC transformers, and common parts.

    Around here lots of satellite and cable boxes get tossed, though they are
    relatively new and offer fewer interesting parts.

    It depends on the parts you need. Something like a "Sony Walkman" would
    offer up a small motor, and likely a small headphone amplifier.

    The thing is, anyone interested in electronics should be keeping an eye
    out, maybe even carrying some common tools to extract boards on the scene
    rather than bringing the whole unit home. To deal with existing pieces of
    equipment is to diminish their power. And since most beginners start by
    going to the parts store and asking for parts exactly as specified in the
    construction article (one kid at high school decades ago said "I'm afraid
    of making a mistake"), salvaging parts is not only cheaper, but a sign
    that they have learned enough to tell when a part can be substituted, when
    a part should stay as it is, and how much leeway there is.

    The first frew projects I tried to build failed, but I went with the list
    copied from the magazine, and didn't yet know enough about things to know
    if I wsa getting good parts or substitues or not. The first things that
    did work were a few months later, me putting together parts I pulled out
    of transistor radios and mainframe cmmputer boards.

    For common parts, this is a fairly readily at hand source of parts.

    Hop over to Jameco. They've been doing both grab bags (random bits, take
    your chances) and graded assortments of parts for decades, since back
    when catalogs and order forms were all on paper. ;-)

    Search there on "assortments" or hit this link.

    Note that they have many of their assortments available both as "kits in
    plastic drawers" and "refill kits in little bags."

    "Assortment" works at Digikey as well. Search on that and then hit Kits
    and, e.g., passive - resistors.
  4. Try a search with the word "kits" (at least at digikey.)
    So "resistor kits" brings up a bunch of hits.

    I like this place for experimental junk parts.

    As others have said, Jameco is a good start. Other sources are:

    Also, I have a large quantity of surplus parts for which I'd like to find
    good homes. Here is a partial listing: and and

    Ignore prices. Most of them I'd only want shipping and handling cost.

    Hey, thanks everybody! Those grab bag suggestions look great and that's the direction I will go.

    Thanks again,
