Publishing Schematics Before “Open Source” Was a Word

1. Pricing terminology confusion
- “that means $5 part is sold for $10. It's exactly how that kind of thing works” – PunchyHamster
- “That's actually a 50% profit margin. Also known as a 50% markup, even though you marked the price up by 100%.” – BenjiWiebe

2. Open hardware kits & nostalgic culture
- “Apropos open electronics, one of my most treasured toys is a Denshi Blocks electronics experiments kit, with a synthesizer chip in it.” – MomsAVoxell
- “Reminds me of a vaguely similar toy you used to be able to get at Radio Shack: the ‘electronics project kits’.” – bitwize

3. Sociology of information sharing
- “I've been thinking a good way to understand the ‘sociology’ of information sharing is the structure of capital or prestige in an ecosystem…” – firasd
