The very first raspberry pi boards have been selling on eBay. As numbered limited edition prototypes they cost a lot. We loved seeing the spirit of the RPi community at work in this story earlier.
We love it because this the spirit of the whole project. Contribution to knowledge and education in computer skills for all. That’s the spirit of this RPi Audio blog as well. We’re here to demonstrate some great audio processing tricks on hardware that can be afforded by almost anyone. The information we give away is free, not part of an expensive textbook.
