The Mark 1 Railgun - "Punisher"

I have finally finished my new gun, I am keeping the design and most of the statistics under wraps for the moment, but If you PM me and ask nicely I will send you a picture, the one piece of information I will tell you is it uses the massive #109 band

UPDATE

picture and real video are now posted below. that is the only picture I have uploaded the rest of my pictures are in the trailer video, and just so you know the trailer video has been on my ob for a few days now =P

Cool knex instructable. Pity I had my hopes up to get something that would work in real life (i.e., a REAL rail gun). Still, thumbs up to the knex players, lego builders and meccanno lovers out there who "invent" from the day they are 5 years old.

screw knex, grow up and learn some electronics and stuff. guyyyysss, i just built a time machine out of knex, a rubber band, and even some legos! it shoots a clock 2 feet! yayyyyyyyy :P
Screw electronics and stuff, let out the kid inside you and make a gun out of knex.

duuuudesssss, i just built a 5000000000 volt generator and shoked myself! i had to go to hospital OMG OMG OMG OMGGGGGG

=P
Time for a k'nex generator. Fusion of wins = a win.<br />
or how about you grow up and do something worthwhile with your time
get a job
build something to sell
build something as a senior project
invent something to enter in a nationwide competition/club like TSA, Science Olympiad, or Siemens.

and btw your comment was idiotic, but you wouldn't know why
No.

BTW, My comment was a parody of your comment, in case you didn't get it.
haha, your a funny little boy, have fun with your toys
Don't worry, I will.

did you look at the trailer?
why didn't you just shoot the gun?
Fred the Penguin (author)  DJ Radio4 years ago
I will.....later
I don't like how there's a bajillion and 1 "BEST EVA KNEX GUN SHOOTS REALLY FAR!!!!@!!" but k'nex itself is not a bad thing.
well it's definiteley coming off as being really lame with all of those headings and stuff
Only the noobs do that.  We look down on those guys just like you do.
glad to see we got one thing straight :P
also what angers me is at this time, 45% of recent form topics are knex...
Fred the Penguin (author)  guyfrom7up4 years ago
I do know how to use electronics, my dad is a qualified electrician, I also know how to use logic to program robotics or other machinery, Im 15 that means I am allowed to use knex if I want too.
Im 15 too, which means that I'm aloud to use high voltage and other machinery and program AVRs and such ;) I'm sorry, I just really hate knex stuff :P
If you don't like it, don't look at it.
Fred the Penguin (author)  guyfrom7up4 years ago
Anyone can tell me what to do, It's getting me to do it thats the hard part. -logic boy
Looks punishing lol.

Ah yes this is somewhat better than that pistol... 
Fred the Penguin (author)  Lowney4 years ago
so you see what I am talking about, but personally I prefer a GOP15. the gun in the picture is 22 yellow connectors long, the version my friend now has is 50 yellow connectors long, he sais he got it to fire over 350 meters, although I am not sure I believe him.....
He meant 350 feet.  I don't believe him. 
Fred the Penguin (author)  DJ Radio4 years ago
neither do I, but I will find out this weekend
 I would find that hard to believe: that is almost 1000ft!
Fred the Penguin (author)  Lowney4 years ago
I don't believe him either

Someone looking for attention?
Fred the Penguin (author)  pls4 years ago
Someone looking for Punishing?
Someone looking stupid? Yes, that would be you.

I don't like it. It looks like it's bent at about 5degrees. Massive problem.
DJ Radio travw4 years ago
I bet he did that on purpose. The tension from the rubberbands would only straighten the barrel up.
travw DJ Radio4 years ago
No. Good idea, but no. Look at the picture, it's cocked, and it's still bent!
DJ Radio travw4 years ago
He only has 1 band on.... Put more on and it will be straight.
Fred the Penguin (author)  travw4 years ago
not at all, its because most of the weight is at the front, so it is sort of leaning foward, it is no problem at all, Its degisn means that it can bend fowars a bit but it cannot ben up, therefore holding a lot of bands
WELL IT DRIVES ME F****** CRAZY JUST LOOKING AT IT!!!
Eh. I still don't like my weapons bending like that. But I see your point.
Fred the Penguin (author)  travw4 years ago
oh and also I usually use 3 more #109's

Fred the Penguin (author)  Whaleman4 years ago
read the topic
I did read it. I am tempted to PM you for a picture and post it all over the net. But then again,
uselessthread.gif
Fred the Penguin (author)  Whaleman4 years ago
I have the picture up now, Ya happy?
Fred the Penguin (author)  Whaleman4 years ago
thats why I am not going to send you one.
When did I ask for one?
Fred the Penguin (author)  Whaleman4 years ago
I meant that even if you ask for one you are not going to get one
Would you have sent me one before I said that I wanted to plaster it all over the web?
Well, he gave me pics; It isn't a true railgun. It doesn't use a cannon barrel to acellerate a block trigger then fires that block at the end.
So... it's pretty much ooda's cannon with the rod firing mod on it?
No, it's not a cannon, it looks more like a slingshot.
So... It's not in any way what he says it is?
Fred the Penguin (author)  Whaleman4 years ago
probably not
Well, you filthy liar. You said you'd send pics to someone who'd ask nicely.
Fred the Penguin (author)  Whaleman4 years ago
actually I probably would of, did you check out the vid?
I'm suspicious of it. Someone reluctant to give one pic would not give a hundred pics.
Fred the Penguin (author)  Whaleman4 years ago
fine then, I will get the trailer soon
And also cjnumber's saying 'I got rickroled!' doesn't play to your credibility.
Fred the Penguin (author)  Whaleman4 years ago
I do have a video, its on my __
You have no pictures or railgun or even anything that resembles a railgun..
Where did you get that picture???
cj814994 years ago
beep I got rickroled!
Fred the Penguin (author)  cj814994 years ago
can you get rid of that comment please
why?
Fred the Penguin (author)  cj814994 years ago
nvm, I got the real video now
Why?

As if we couldn't guess...
Kiteman4 years ago
I'm not even going to bother with the video - you cannot build a railgun with K'NEX, since the rails need to be conductive for their full length.
Fred the Penguin (author)  Kiteman4 years ago
Well, It is as close to a railgun you can get with knex, the two "rails" guide the projectile and the rubberband accelerates it, do you think that I did not know how a true railgun works, you need very powerful electromagnets and ferros projectiles for a start, not a standard part of a knex set.
...and do you think we'd all fall for a rickroll?
Fred the Penguin (author)  Kiteman4 years ago
cj81499 did and I have the real trailer video up now.
DJ Radio4 years ago
Please send me pictures. I want to tell you how you can improve your gun.
Fred the Penguin (author)  DJ Radio4 years ago
read the topic
I was actually requesting pictures. I read the topic all right.
Fred the Penguin (author)  DJ Radio4 years ago
fine then I will post the one picture I have left on one of your older things
