The Claymore mine is a rather fearsome weapon of war, using explosives to blast a cone of shrapnel towards advancing enemies. It’s not really something you should try and build at home. An airsoft version, though, is altogether more appropriate. [RegiBlackwood] has developed a simple way to build exactly that.
It’s a cheap and cheerful build, with the claymore housing itself built out of cardboard. Wooden dowels are used to stake it into the ground, just like the real thing. In the center of the housing sits a regular old mouse trap. Only, it’s been modified to hold a sling carrying a payload of BBs. The trap is also tweaked to make its spring more powerful, and to enable it to be triggered with the tug of a tripwire. When triggered, the mousetrap fires and hurls the sling forth, spewing a rain of BBs from the front of the device—ideally quelling the advance on your position.
Built properly, it’s a fun piece of airsoft hardware that could really change the dynamics of your regular game. If you’re looking to do point defence, you might also consider building yourself some automated turrets as well…

Cause of the serif.
I shot the serif, but….
The Claymore has to be the mine with the biggest fan base. Can’t think of another explosive trap that commands such a following.
Simple, Reliable, Scary, and Effective!
Also easy to be used by your enemy. 1/3 of US losses in Vietnam was to mines (mostly reused Claymores).
Rat trap with a strip of fabric works nicely. Add a hole in the centre and a string connected to the bait lever for the trip wire. Did this a few decades ago.
” (and no, I am not American).”
— Well I am.
“gun ownership is a deterrent to criminals”
—That has been proven false(no…not going to find links at 5AM)
And I have guns….many.
But we have too many “whack jobs” in the USA with AR-15’s
ok.
Here, I’ll supply the report…but you’re not going to like what it says.
In a 2013 study, titled “PRIORITIES FOR RESEARCH TO REDUCE THE THREAT OF FIREARM-RELATED VIOLENCE” by the Institute of Medicine and National Research Council of the National Academies, they found somewhere between 60,000 and 2.5 million (yes million) instances of defensive gun usage in the United States.
Why the large range? Well, it turns out “defensive gun use” is poorly defined, and even more poorly tracked. If someone brandishes a weapon to fend off a mugger, but doesn’t fire a shot, is that defensive gun use? And even if it is, the likelyhood of that attempted crime being reported is next to nil.
So, no, gun ownership being a deterrent to criminals has not “been proven false.” I’d say quite the opposite.
Go ahead, google the report and read it yourself. And remember this was produced in 2013 – peak Obama years, not Trump/MAGA era.
Well, in that case you better give kids more guns, because US kids are apparently insufficiently armed to deter school shooters. /i
that only 9 of the 23 comments (as this is written) are visible, is a hint as to the hot debate about topics as this. hackaday, please take the hint.
Could you give me a clue about what the hint is? I’m unfortunately clueless
some people find weapons offensive. even if they are defensive. like people in the usa find it offensive to talk about or use words describing the process of making babies. i still dont understand why those words ( i even cannot write them here) are banned, but not the words kill, murder, massacer. taboo is a culturally localized thing.
