As an EE/firmware engineer working in the field, don't listen to the naysayers. Just because it's not some 10 layer RF board doesn't mean it's not a rewarding project and a worthwhile product. For the record, the products we design and assemble in-house are only 4 layer boards, and our business is doing just fine.There's too much elitism in engineering. I think the article is awesome; you found out a lot of pain points that I deal with regularly. The only nitpick I have is that I wish more people were on the side of open source hardware than patents.
