Electronic circuits
Intro
A lot of Splat'ers are into electronics / Arduino / etc.. and here are some interesting links to articles and stuff for the electronics hobbyist.

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 short comparison of sources for PC board fabrication suitable for prototyping. These sources create production or near-production quality boards: plated-through holes, solder mask and silk screen on both sides. The first four sources have relatively long lead times, while the last source offers very fast turnaround (and very much higher prices to go along with the speed).

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.
