LI 1020BR

Step 1: What You Need

- A transformer taken out of an old usv. Mine was from a LI 1020BR from Best.
- A stone, a really nice on, mine was from a beach on teneriffe, from my last holidays
- Nuts ...

Step 2: Build an Use It

Take the transformer out of the usv and place it on the table.
Get the nuts and put them beside the transformer.
Take one nut place it onto the transfomer.
Take the stone and hammer onto the nut.
Yummy ... :-)

    caveman style!

    thank you .

    though cavemen were cool

    Not what I was looking for, Embarrassing for the instructables..

    hahaha! Best instructable ever! Nice music.. bytheway!


    It seem to work. lol

    That poor Transfomer it could be put to good use in a invertor or a nice psu. :'( its a big one as well hard to find because people like small crappy ones.

    why don't you just short the primary and secondary and blow them up.

    anyway... nice sense of humour dude...

    Wait - where's the wire diagram explaining how you hook the transformer up to the stone? ;-)

    yeah i agree with you...

    Ahhhh - right ... I knew I forgot something .... ;-)

    good prank!

    no offense, but this was waaay below my expectations. for two reasons. people that do not have enough fantasy to find two hard objects to smash shelled fruits are mentally challenged, and therefore need help from sources they can trust more than you should trust something someone can write on a website somewhere on the internet. an instructable can be forced into this step, when you add, that the surface you smash can be on a soft surface, as your lap for example....., as long as it is heavy enough to develop enough inertia when being hit through the nut with your handheld weight. i use for example a flat metal piece, about 3 kg heavy, to crack nuts in my lap while watching tv. my nutcracker broke down. then, you can possibly add another comment, about the handheld piece of the machinery. it should be heavy enough not to bounce back, and light enough so that you can lift it without getting tired after your first five nuts. its mainly trial an error. then, it should fit comfortably in your hand, for the same reason. its shape must be appropriate, or it should have a handle. like a hammer for example.... the second reason why this instructable disappoints me is that i expected some kind of device that cracks nuts for itself. perhaps by the same principle, with an automatic lifting device of the stone..... that should drop it from different heights....adjustable of course.. and a conveyer belt to keep bringing nuts.... but hey, that's just my fantastic piece of machinery, so this unfulfilled expectation goes on my account....

    This guy for real? It was a joke.

    It is'nt easy to build,only for experienced craftsman ,but very useful,good also for fingercracking !

    ummmm, how is this " Nice looking " ? It kinda looks like it came from the side of a highway...

    It's kinda lame, but funny I like it

    Cool Instructable, I used to have one when I was small, but then it broke. :-(
