Cannon-Sized Slingshot Fires 80mm Steel Shot
For those of you without metric intuition, 80mm is about pi inches. For those of you without metric intuition who flunked geometry, it’s about 3.14 inches. Which am big. Like, cannonball-sized.

Responding to criticisms that their new no-trolling-allowed policy lacks teeth, Hack a Day writer Jack Buffington threw down the gauntlet Monday, announcing that, henceforth, anyone leaving a nasty comment about one of Jeri Ellsworth’s projects will receive a visit from the Pain Fairy.
Although I believe this impressive, apparently working wooden rubber band gun and the page that presents it originate in Japan, I’m not having any luck with machine translations of the accompanying text. So unfortunately I have no other information. If you can identify the maker or other details, and can spare the time, I’d appreciate your comment, below.
I have seen a lot of steampunk rayguns come and go, over the years, but not any that I can remember liking as much as this set of matched-but-not-identical “dueling pistols” from Canadian artist Jeff de Boer.
OK, in point of fact, this cool gadget from Matt Bitz of Liquidware could be used for pretty much any type of marksmanship training, but “sniper” was a pretty hard headline to resist. It couples Liquidware’s TouchShield Slide, an Arduino Duemilanove, and a lithium battery-pack in a camouflaged aluminum case for a handy range-gadget that records hits on a target—just tap the touchscreen with the tip of a round to mark a hit—and calculates accuracy and precision in real time.

When I first saw this shot from user eqqman in the MAKE Flickr pool, my thought was, “Oh, look, some tourist photographed a cannon in a park somewhere and tagged it for our pool. How odd.” Reading the fine print, however, tells the story…
Yes, OK, I know that the weapons in Iron Man’s palms are technically *repulsor* beams, which, at least as I understand them, are a kind of wholly sci-fictional counterpart to the equally sci-fictional “tractor” beam. But this terrifying device from German laserhacker Patrick Priebe, who previously has produced a handheld Nd-YAG pulse laser that will punch holes in, is “working” in the sense that it is a dangerous, if not deadly, directed energy weapon that you can wear on your palm and use to work great evil…
