That's a nice free gesture. I thought of creating some DIP adapter nvram boards and putting them out for free a few years back, but I'm pretty unclear of how support and liability would work on open sourced designs in general. I figured regardless if you offer something for FREE or $100.. if it can be tied back to you, it increases your exposure since you were the person that put it out there. Not really a settling thought to me, so I never went down that free path heavily. There's simple diagnostic tools I'd have put out for free otherwise. It's all exposure though if people misuse the stuff, at least that's how I see it.
Maybe open source hardware doesn't work that way. But take a more extreme example of a design that works with mains voltage & makes it easier for someone to injure themselves or their property -- and it can be tied back to the designer. I'd think there'd be some liability concern there.
Just some thoughts I've had a long the way. Kudos for offering something up for free like this, hopefully you don't find the support or liability aspect to be an issue. As I said, I really don't have a clear idea of either -- just assumptions. Uncharted territory for me and I'll probably keep it that way.
