Jörg Sprave, the man with the greatest smile on the internet and the face of the "Slingshot Channel" on YouTube, has created a fully automatic crossbow:
When you make non gunpowder weapons at home, you are usually restricted to single shot contraptions or manual repeaters at best. But of course the ultimate goal is to build a full auto machine gun style weapon!
That is by no means very easy. Muscle powered weapons are simply not quick enough for a true brat-a-tat action. Gas powered engines are too heavy and clumsy for a portable weapon.
Of course there are modern battery drills - plenty of torque in small packages, lightweight and affordable. It makes sense to use those as power sources. But how to turn rotational motion into a linear cocking process?
We finally, at last, had success using a rack and pinion mechanism. The wooden gears had to be reinforced with solid aluminum for a reliable operation, but the result is very convincing.
It is a reality - true machine gun feeling!

More for you:
"Dravens Tales from the Crypt" has been enchanting for over 15 years with a tasteless mixture of humor, serious journalism - for current events and unbalanced reporting in the press politics - and zombies, garnished with lots of art, entertainment and punk rock. Draven has turned his hobby into a popular brand that cannot be classified.
My blog was never designed to spread news, let alone get political, but with current affairs I just can't help but capture information here that is otherwise censored on all other channels. I am aware that the design page may not seem "serious" to many in this regard, but I will not change this to please the "mainstream". Anyone who is open to non-state-compliant information sees the content and not the packaging. I've tried enough to provide people with information over the last 2 years, but quickly noticed that it never matters how it's "packaged", but what the other person's attitude towards it is. I don't want to put honey on anyone's mouth to meet expectations in any way, so I'll keep this design because hopefully at some point I'll be able to stop making these political statements, because it's not my goal to go on like this forever 
I leave it up to everyone how they deal with it. However, you are welcome to simply copy and distribute the content, my blog has always been under the WTFPL license.
It's hard for me to describe what I'm actually doing here, DravensTales has become a culture blog, music blog, shock blog, tech blog, horror blog, fun blog, a blog about found items on the internet, internet bizarre, trash blog, art blog, water heater, zeitgeist blog over the years , Scrap blog and grab bag blog called. Everything that is right ... - and yet not. The main focus of the blog is contemporary art, in the broadest sense of the word.
