Hey Grant,
Nice to hear from you. Shame you didn't make it this time. We had a good group but there was plenty of space for more people.
Your project is very interesting. I would like to see it. Maybe you can make it to the next meeting in August.
Also consider the SF Pi Meetup. It is every other month first Tuesday at Google launch pad in downtown. I think the next one is September. Maybe you can present your project.
Anyways I'm still trying to learn Arduino. But it is taking me a while. Haven't tried any programming in like 20 years but it is coming back to me. Similar to C I think.
Again, hope to see you soon.
Thomas
