This is probably mostly a 'problem' in my area... I love to create stuff out of discarded things, scrap and waste.  But there aren't really 'junk yards' around any more.  

Where in the San Francisco Bay Area can you get inexpensive/free materials?  I'm not afraid to dumpster dive, but even there, the resources are slim pickings in an area that recycles so assiduously!

Use the LCD in Red to preserve nightvision... What about something like a pixel ring that can point out the direction from which it will approach and recede?

I'm pondering the idea of getting a laser cutter for home. I'm lucky enough to be kind of near a TechShop, but not quite close enough.  Any advice on how to begin shopping?

Yeah, I can see that anything less than an Epilog will be a stepping stone. But I don't think I can do that just yet. I've also considered some of the CNC options that would allow me to cut thin plywood.

I've been inspired by various passive solar projects.  One of my favorite project ideas is to supplement my hot tub heating with a solar water heater.  I've seen various totally passive designs, and some with just pumps, but these don't seem to deal with the possibilities of cooling your water by pumping it through the collector on cold days, etc.  I have used temperature controllers before, but most tend to have a single sensor.  This project would need two sensors, with logic that only pumps water through the collector when it would be efficient to do so.  There are pre-made solar water controllers out there, but most are intended for supplementing water heaters.

Any advice on where to get started sorting out the options for a solar hot tub heater that can sense the appropriate temps?

How do Iook up someone's profile in Google+?  I want to browse through a friend's public photo albums but can't figure out how.

I thought that wasn't working because so many people were coming up without any information at all... ;)

And I had a couple of people that used to share stuff that they must have hidden, so it took me a while to figure out that it was working as expected.

A guy I work with at VMware is heading out in a couple of weeks to row across the Arctic Ocean.  Neat.
Seldom in life do we get the opportunity to participate in a ‘first.’ This summer, VMware’s own Neal Mueller, Product Marketing Manager for busines...
