Simple parts sources

[Ivan Vegvary]

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

Check out JAYCAR or ALTRONICS.

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.
<http://www.jameco.com/webapp/wcs/stores/servlet/StoreCatalogDrillDownView?langId=-1&storeId=10001&catalogId=10001&freeText=assortments&search_type=jamecoall>

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.

Get a Jameco catalog they have some serious parts kits, as well as
Arduino shields sensors etc..

www.jameco.com
Look under "component kits" and "grab bags"

Picaxe is a good learning tool too. Easier, cheaper and better
supported than the Arduino but with less capability.

Try a search with the word "kits" (at least at digikey.)
So "resistor kits" brings up a bunch of hits.

There are some Arduino 'starter kits' on Ebay. You can also buy
assortments of resistors, capacitors & crystals there.

I like this place for experimental junk parts.

Try Jameco, they may have grab-bags.

As others have said, Jameco is a good start. Other sources are:
http://alltronics.com/
http://www.herbach.com/Merchant2/merchant.mv?
http://www.mpja.com/
http://www.sciplus.com/category.cfm/subsection/2
http://www.surplussales.com/

Also, I have a large quantity of surplus parts for which I'd like to find
good homes. Here is a partial listing:
http://pstech-inc.com/PARTS.txt and
http://pstech-inc.com/PARTS.xls and
http://pstech-inc.com/surplus.htm

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,
