Components / Parts Suppliers
See Electronics Parts Orders for group orders with other *Space members. Group orders are a good way to save on shipping costs, and on component costs through volume discounts.
- Summit Electronics - good place to find obsolete / hard-to-find components
Prototype PC Board Vendors
Here is a trivial comparison of sources for PC board fabrication suitable for prototyping. All provide boards with plated-through holes, solder masks and silk screening. The first four sources are hobby-oriented and have relatively long, "it is what it is" lead times, while the last source is a highly regarded pro vendor. All but Seeedstudio offer ENIG (gold) finish and this was used for comparison and should be considered to keep the Seeedstudio price in perspective.

Using MOSFETs with Arduino
Using Power MOSFETs with an Arduino, to control high current / high-voltage devices, is not always as straightforward as it might appear. Here are several articles and Arduino.cc forum threads that speak to using MOSFETs / using MOSFETs with Arduino.
