Get your smash on at “sport” bottle recycling center

Get your smash on at “sport” bottle recycling center

When I was still living in Dallas, our local recycling center included a giant steel dumpster, open at only one end, with an elevated platform you could climb up to chuck your glass bottles in. I was in high school, then, and it was pretty common, when we were bored, to go down there on the weekend and pass an hour or so smashing glass bottles into the dumpster just for the fun of it. You’d see “grown-ups” there doing the same thing, and more than once perfectly “respectable” suburban adults would see what we were up to and join in, which inevitably put a big grin on everybody’s face. I’m sure this kind of impromptu bottle-breaking game happens naturally at recycling centers all over the world.

Lego pressure sensor

Lego pressure sensor

14-year-old blogger and LEGO fan Joey Kelly of Stayton, OR lucked into a pressure sensor from Dexter Industries, and wrote up a detailed report. The dPressure is a very interesting sensor. It has two nozzles: the first on can sense pressure in both PSI (Pounds per Square Inch), and kPa (Kilopascals). The second nozzle can […]

BrickLink is like Craigslist for Legos

BrickLink is like Craigslist for Legos

Have you ever seen any of the amazing custom Lego work proliferating on the internet these days and wondered, “Where did they get exactly the bricks they needed to build that thing?” Sourcing parts can be especially difficult if your model, like Flickr user Legohaulic’s Great White Nautilus, shown above, includes lots of unusual elements. As far as I know, there is, as yet, no site or service in the world that will let you upload a list of Lego elements, in exactly the colors and quantities you want, and then price, pack, and ship you an order containing exactly those elements. It seems like a great idea, but the logistical problems of making that happen are enormous. BrickLink, however, is the next-best thing. Thousands of private Lego resellers from around the world have shops there selling kits, manuals, and individual elements indexed by official Lego catalog number. If you’re sourcing parts for a particular model, you still have to do some manual legwork running down the particular combination of BrickLink sellers that optimize price, availability, seller location, seller minimum order values, and so forth for the items on your list, but it’s still an incredible resource.

Backpedaling, but in a good way…

Backpedaling, but in a good way…

MAKE subscriber Steve Hoefer sent us a link to this fascinating piece on retro-direct drives for bikes. Not really sure how practical it is, but the engineering is interesting. And, it’s probably a great way to work different leg muscles. What’s a retro-direct bike? At the beginning of the 20th century, although derailleurs and geared […]
