Other stuff

If you are interested in purchasing electronic components for building projects, here are some links to places we buy parts from.

Jameco Electronics - We used to buy most of our stuff from Jameco before they "improved" their web site. It's now more difficult to find stuff on the web site so you may be better off requesting a printed catalog or looking through the PDF version of the printed catalog. It's usually easier to find parts in that catalog than online. It will also get you on their mailing list for future catalogs.

Digi-Key - This is our other primary supplier. They have a large inventory, the prices are reasonable, and we usually get the order pretty quickly. They send out a printed catalog of over 1000 pages. However the size of the catalog sometimes make it hard to find things.

SparkFun Electronics - This company sells a lot of interesting items for the hobbiest/experimenter. Their inventory changes a lot so you might not be able to buy the same things six months from now.

Parallax, Adafruit, DFRobot - These are similar to SparkFun in that most of the stuff is for the hobbyist.

Modern Device - They seem to have a interesting variety of components including many sensors and related components.

Newark and Mouser Electronics - These two are major suppliers to the electronics industry with very large inventories. Not sure if they have minimum order amounts that may make it hard for the hobbyist but they are worth a look.

All Electronics - This is basically a surplus store with both new and used components. Their prices on some stuff is very good, provided you can find what you need. You can also visit their store at 14928 Oxnard St., Van Nuys.

B.G. Micro - They sell a wide variety of interesting stuff. Download their PDF catalog.

Apex Electronics, This is a large electronics surplus store in an industrial area of the San Fernando Valley (8909 San Fernando Road, Sun Valley). If they have something you need, you can probably get it at a good price. It's sometimes hard to find things, but it's worth at least one trip there just to see the place, and its storage area outside in the back.
