This is ps2chiper and atommann from the shenzhen linux user group. We saw the news for psgrove and I convinced atommann to use his avr skills to design open hardware for psgroove to stop pirates from profiting. Our goal is to sell the open hardware at cost to anybody who wants it. attached to this thread is a alpha design created on geda. We will let you guys know when the final design is done and the price seems to be around 3 dollars each. Rename to tar.gz after you download it.
