Other stuff

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

Digi-Key - This is our primary supplier of electronic components. They have a large inventory, the prices are reasonable, and we usually get the order pretty quickly. However the size of their inventory sometimes makes it hard to find things.

Jameco Electronics - This is another supplier we use for supplies. Their inventory is smaller than Digi-Key and it's sometimes a bit easier to find things. They used to have a nice printed catalog but not any more.

Adafruit, SparkFun - These companies sell a lot of interesting items for the hobbyist/experimenter. Both companies sell a lot of "breakout boards" where they have mounted small IC's that are difficult to work with on PCBs what make connections to the IC easier.

Parallax, DFRobot - These are similar to Adafruit and 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.

Apex Surplus, 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.
