Homemade Revolving Shotgun
From Home Gunsmith Forum user rhmc24: Using chambers cut off 12 ga. scrap barrels and a new $10 bbl for an Italian auto shotgun, the only other gun part is a scrapped hammer from a 1857 Remington perc revolver. Loads like a SAA Colt but underlever rotates and cocks it. Blow-by is negligible, hardly noticeable […]
Giant Outdoor Catan
A Burning Man project from 2007, the giant Settlers of Catan game now appears at various conventions and festivals.
Mechanical Pac Man
Toronto’s Jonathan Guberman loves his games. We’ve already seen his typewriter Zork and Game of Life monome. His latest project is nothing less than a mechanical Pac Man game. Still a work in progress, the plaque above seems to be a study of sorts. See Jonathan’s site for his build notes.
High Altitude Paper Airplanes
Project Space Planes is a publicity stunt, but a fun and interesting one at that. Launch 100 paper planes with a particular brand of memory cards containing messages sent in from people across the Internet on a high altitude weather balloon and see what happens. Well, it’s been a couple of weeks since they launched and results are still streaming in. Currently the list includes a number of unconfirmed reports of planes found in places like Germany, Australia, Russia, India, the Netherlands, California, Canada, and South Africa.
Lego Servo Multiplexer
A NXT brick can control only three servos, but don’t let that limit you. This multiplexer — dating back to 2007, an oldie! — uses two servos to do the work of twelve, thanks to this clever homebrewed multiplexer.
Gallery of Spherical Cockpit Panoramas
The field of panoramic photography needs some better terminology, IMHO: “360-degree panorama,” it seems to me, could just as easily apply to a circular panorama of, say, the horizon, as it could to a fully spherical panorama that also includes up, down, and every other direction in space you could possibly look from a particular point. Or maybe the term is already out there and I just couldn’t figure it out? If you’re in the know, please share below.
