2 square meters of sunlight, focused, will melt anything on Earth

And you can watch it happen in this literally awesome video from the BBC’s Bang Goes the Theory. I wonder how much that lens cost? I’ve got a shed out back, wouldn’t be too hard to cut a hole in the roof… [via Boing Boing]

Sandcast aluminum ray gun, with bonus pour vid

Sandcast aluminum ray gun, with bonus pour vid

Craig Bush saw our recent post about Ryan Palser’s Fallout 3 replica weapons and thought we might be interested in this photoset of his home-poured aluminum Call of Duty ray gun replica.

Featured Maker: Shannon Conrad

If you follow CRAFT, as well, you may have seen Rachel’s post back in January about Oregon jeweler Shannon Conrad’s interlocking Lego rings.

Von Slatt’s gas and waste oil foundry furnace

One downside to being a big fan of a particular maker is how long it can seem between new projects on his/her site, entries of a multi-part projects journal, what they had for breakfast, anything. Certain builders, I go to their sites (or look at their newsfeeds) obsessively, and it can be maddening waiting for […]

Charcoal foundry build at Chicago hackerspace

Tim Saylor recently wrote in to me about the Gingery-style charcoal foundry he built for Chicago’s hackerspace Pumping Station: One. There’s a write-up here and a good Flickr set showing construction and use of the furnace to melt aluminum here, including some really pretty shots of the fire and sparks at night. [Thanks, Tim!]
