I wanted to make the community aware of a Kickstarter campaign that I recently launched for an Arduino shield. The Extended DAC Shield is a high-speed, high-precision, eight channel, -10V to +10V analog output shield for the Arduino. The design will be open source with schematic, layout, and source code freely available.
If you have any questions about the shield or campaign feel free to ask them here. Please help us raise the funds necessary to make this awesome shield a reality!
