On July 30th in SF I'm organizing an "Map-a-thon" to put together a hardware resources map (like where to buy electronics, metal, etc. locally) for the SF area using a simple gMaps embed and some KMLs.
There also needs to be a "CrunchBase for hardware" because no one tags things "hardware" - it's always "fitness", "maker" or whatever category they're targeting.
We're also doing a survey soon to get some case studies on how people are building these companies.
Finally, we're looking at putting together a knowledge base for how to make things like "How to Design for Injection Molding" - etc. It's easy to find "How to Build X in Rails" tutorials - we need the same for our community.
