I just got a PM back from Bennelson. He says the link to donate to Paul is still up to date and can be used. I'd highly encourage anyone with an interest in seeing this project go forward just toss Paul a few bucks. You get a bunch of people to donate even a little bit and it adds up quick!
Click the link and then click the donate button in the upper right.
Donate to the open source AC controller project!
Amazing stuff Paul, thanks for the hard work!
