Material+Resources

Here are some links to electronic and mechanical components distributes. Feel free to add links to any resources you feel would be helpful

Electronics
Excellent resource for those just getting started in electronics or looking for more complete or general components as opposed to specific individual parts. They have many premade modules, provide good general information. [|Sparkfun]

Electronic Components
These websites are great if you are looking for a specific electronic component and have a good idea of the specifications you need. They have a very large selection of very specific parts, but as a result the site can be a little hard to navigate.

Mechanical Components
If you are looking for mechanical components beyond what you can find at the hardware store this is a great resource. Much like the electrical component websites, it has a huge variety of very specific parts. [|McMaster]

Microcontroler
Here is a link to the Arduino website. They have a variety of microcontrolers including the Arduino Uno, which can be purchased on the Sparkfun website. [|Arduino]

Linear Actuator
Here is the link to the site where I find the best resources for the actuator that Rogers used. [|AEI.com]
