Um, hello, welcome. I was just going to kick this off by saying big ups to Ayah and Alicia! [applause] OK, so, a really quick introduction. I'm Limor Fried, I run Adafruit Industries which is in downtown Manhatten so I got to take the 7 here. And um I've been doing open source hardware and selling it as part of this business since 2006 and I've got really good news all of you who've heard me talk I'm actually not going to talk about my business. Um, because Ayah and Alicia said "hey we want, you know, pragmatic, hobbyist, you know, solutions-based driven stuff" and I was like OK you know I'm not going to talk about all the details of shipping, manufacturing and licensing and all that stuff. I'm actually going to talk about "Why Do Open Source Hardware?" and specifically why I did open source hardware and ah, maybe some of the reasons why you may want to do open source hardware if you don't. Um so OK, so we're going to rewind back to 2002 and 2003 we're going to stop at 2006. So it's all going to be history. So, you know, I grew up in Boston and, uh, Boston is a bit of a sea of you know, the FSF, the EFF used to be there too. So there was a lot of like, you know, Linux-y, BSD people hanging out there and I went to MIT. So there was a culture of open source software. So it was sort of assumed that if you were going to work on something it would be an open source software project, you know install Linux, you were running it, it was totally cool and Microsoft sucked. And so when I started moving away from doing software and doing more electronics um, there were sort of I had this uh you know core of like "oh, open source software is good, and I've seen the good it does." And so I was definitely inspired by that. So it's not like I came up with open source hardware out of nowhere. It's a derivative of open source software. And uh what I would do when I was learning electronics is that I would release stuff like these are some earlier projects that I did some development boards and stuff when I was in school and I would release you know they would have software and firmware and I would release the software and firmware under like GPL or MIT or BSD license or anything or whatever the popular license of the time was. But I would put the files up and I would say just ah you know "these are the Eagle CAD files and the Grouper files and I guess do what you want with them." But like the idea that you could even license them actually I had no idea I didn't know about like mass works or what was copyright or schematic copyright or is it patented or what? So I just put it up and I said "you know, whatever, you can enjoy it yourself." So for example and I'm going to go through specific examples of projects and why I open sourced them or why I published them.
