I've reached the end of what I can reasonably do without re-spinning the board, so out it went last week. I expect to see the new ones by the end of this week, and I'll post a nice picture when I get the boards back. I hope to assemble and test next weekend. I expect to get some RF code from some folks in Germany who are working on a similar problem.
I've secured enough capital to get the first three products I announced back in April into production by the end of September if not sooner. This has been held up a little bit by price increases from International Rectifier -- I re-designed the sixteen channel board to use IRF's IPS6044 four-channel high side switches. This reduces the cost below where it was before, which is a happy thing.
