How to Diagram w/Fritzing

When you’re first starting out with electronics, it’s hard to know how to make good-looking, easy-to-understand diagrams of your ideas and creations.  But doing so is a huge plus when others are trying to help you!

Luckily, there’s a free program named Fritzing that makes physical, schematic and even circuit board diagrams very easy.

Here’s a great introduction to how to use Fritzing – if you have questions, add them in the comments or in our Forums!

Connect an AT Switch as a PC Keyboard for under $20

People with physical challenges often are very limited in their ability to make precise movements with their arms, fingers, etc.  (This is known as having poor “fine motor” control.)

This severely limits their ability to control things like keyboards, mice, pens and pencils.  If the person is also unable to speak, they may have no way to communicate.

Our First Project: A Switch Enabled Cariboo Game

This site is our first attempt to express a simple idea:

Open Source Hardware (and Software) provides tools that the Assistive Technology users could benefit from tremendously.  Let’s make that happen.

Our first project will be to create complete instructions for the Switch-Enabled Cariboo® Game we created for display in the booth.  Hopefully, this will lead to more detailed discussions of how the amazing low-cost commodity hardware now available to Makers can help those who rely on Assistive Technology.
