Yes, it's still active. I've created a mailing list and google group just for the counter project. [email protected] to keep the counter project from going out to all 800 time-nuts.
The discussion seems to want to take place here however. :) I've been trying _not_ to be the lead of the opencounter group, but rather to enable it. So far it doesn't seem to be working. I guess I'll spin up another round of benevolent dictator effort and say 'Yo! Over here!' (I got a 5370B shortly after starting the opencounter group, so my immediate need got taken care of, but that doesn't mean we still shouldn't build an open counter. ) An FPGA based solution sounds quite flexible and attractive. I have a Diligent NEXSYS sitting on the bench next to the 5370b as a matter of fact. I'm sure we could get all the speed needed out of an FPGA, but the analog i/o might get to be the tough part. I don't know enough however. I think your email got eaten by the spam filter. I'll respond to that shortly.
