The K'nex Innovations Challenge (KIC) - Round 1 (UPDATES, PLEASE READ) Answered

Seeing as a lot of interest in the challenge has been expressed, the judges and I have decided to host this round now.

This round's chosen topic is: Weapons

Any weapons are permitted for posting, so long as:
 -They are functional - all guns must fire.
 -They are your own design - this means that no modifications of other guns will be accepted.
 -They are posted between the deadline times. Any posted outside these times will not be accepted. It is also not acceptable to re-post.
 -They are posted on the site in the form of an Instructable, Slideshow, or Video. The more detailed your submission is, the more likely we are to understand your submission. Please use correct english and annotate where appropriate - we are judging on many criteria!
 -They only use K'nex pieces, rubber bands (or other means of elastic potential energy storage) string and tape. Cut pieces are permitted, but do take into account that more cut pieces won't get you better marks. We are trying to maximise the potential of K'nex, not mutilate our pieces!

Please post your entries at any time from:
12:00 Midday GMT September 1st
and no later than:
12:00 Midday GMT October 1st.
(Central American Time = 6:00 AM)

Entries will not be accepted if they are posted beyond the deadline, no exceptions.

To submit your entry, post an Instructable, Slideshow or Video of your weapon, titled "KIC Entry: <Your username> - <Submission Name>" You must post a link to me on this forum topic, or via Private Message.

Judging will commence immediately following the final deadline. The top 20 highest-scoring entries will qualify for round 2.

Please use this topic for general discussion and submission - no spam please, it makes judging and entry accepting much harder.

You have one month. Good luck!

List of Entries:

EDIT: Thanks to a suggestion from TheDunkis and Dj Radio, I am allowing teams to work on a single project in order to share ideas and optimise the weapon.


Keep posting people! We've just passed halfway through round one :)

I want to start entering these KIC's, but how will i know when a new one is posted? Because, im guessing round 2 is going to start soon.

I'm not sure about the other 2 judges, but I'll post my rankings for this contest, since there were only 6 entries, including Jollex, except Jammy didn't update it to reflect this. We didn't get too much innovation in the entries, so after I went through all the innovative entries, I sorted it by execution and performance.

1. Jollex's Mag fed slingshot pistol- It's a mag fed slingshot pistol, the first of it's kind. 'Nuff said. This easily wins an innovation contest hands down.

2. Seleziona's SIHM2- This concept has been done before, but this is the first finalized version. However I consider the execution of this rather poor and impractical.

3. Beanieostrich's IFPP5- Wow, we need to name our stuff better. Anyways the concept in this one has been done before by Dunkis, but Beanie keeps it fresh by compacting it and putting it in pistol form.

4.knexfreak 360's double shot assault rifle- We've seen plenty of these before, and sometimes in better form, but the execution displayed here is rather clean and efficient.

5. Rec0n's M4A1 SOPMOD- There's been plenty of M4 replicas on this site, but this one is better than most. I'm not sure why rec0n was entering a replica in a contest focused on innovation though.

6. Masterdude's MHC- If you look at Masterdude's past track record, you might find that a lot of his guns use a similar pseudo-semi auto slingshot mech, and this is just slightly bigger version of his previous works, with larger ammo, which pretty much loses you points in a contest like this. I was also not really a big fan of the construction of this gun.

Why did you not make something?

He was a judge, judges were not allowed to enter stuff.

You always vote through your "mates" on ibles dont you.....

Mates? I'm not Australian, sorry.

Its not an australian word..... its used in other parts of the world.

Whatever. Point is that this wasn't bias at all. I think you're biased against first place because of the trigger, completely ignoring the fact that the crossbow pistol had a 100% new and original concept.

Yes, the gun works or it doesnt..... its either one...

It most likely does, you just have a funny trigger on it.

Your so stupid, the trigger is REVERSED! Now, tell me how on earth i could make that wrong?


That's what I meant by funny trigger.

Also, DJ Radio and I hate each other.

Bias aside, not rating yours, I'd say DJ's list is pretty much where I'd place the other five anywho. But you really are the only one that did anything completely new with a handle fed crossbow.

So when are the other judges gonna do their thing? I wanna get the second round happening.

Can I enter this and mikeasaurus's contest with the same gun?

Please Reply ASAP

My idea I won't say much about but Ill leave you with a "Shotgun Type, not seen before"

It probably won't work though "/

I think you're fine, we just have to wait for Jamalam to edit your entry into the topic.

Hey jamalam i have my entry done but i have a lil problrm i left my camera at my dads house so yould i be able to post pictures a little later than the deadline maybe thursday gmt time please thanks ill be home on thursday with my camera so it will be my first job on the list obviously if people who have entered the copotition do not want me in then i wont but yeah thats all thanks hope this will be sorted ..

Knex Mad =D

Heres mine:

This comment section is here to post entries. Simply saying "I'm not in" is just pointless.

I'll recreate my old handle pump while I'm at it. Expect it in a few days if I get around to it.

Meh, guess I'll "team" up with someone whoever wants. However, I won't be able to build anything at all, simply too busy to fiddle with K'nex and I'd like to keep my gun in tact (showing off my UMP to whoever desires on campus). So I'll share ideas and guide your builds, but that's the best I can do.

Haha, again? I guess I did a good job just leaving all the work to you last time. >_< Alright, have any plans already? Else you probably know exactly what idea I'm going to jump to if you need one.

I have an idea I've been working on, I'll send you some pictures and description.

Alright, cool. Anticipating.

hey guys, thought you should know that Instructables is hosting a K'nex gun challenge starting next week!
Here's the info.

They'll have to remain separate, but you can always enter both!
