I BUILT THIS FOR THE I MADE IT CONTEST!! As you can see i posted it the day of the deadline :)

This is my new creation! It is coin operated and designed for quarters.
If you drop in a penny, nickle or dime, it will just take your coin. :)
For every quarter, one gumball is dispensed.
Please read:
I also built lock and key mechanism for safely storing the collected change.
Unfortunately I didn't have enough knex to finish the rest of it :((
I ran out of green rods and 3D connectors.

So i am left with a random lock and key system with no way to attach it to the bottom of the machine.
I Hope the Coin Operated Gumball machine alone is enough :)

Can u post the lock or is it already somewhere on the site?
nhurtado24 years ago
Thats totally false. In the other video you can see better that you don't introduce the quarter. It is just a mechanism that makes that always you turnthat thing, a gumball cames out.

We have a gumball dispenser before we have a K'nex dispenser. -_-
Good job, though. Now, do you suppose you could make one large dispenser for all the different connectors and rods? It'd be kind of strange to store K'nex in your K'nex but I've been waiting for someone to try this out for as long as I can remember.
And you don't by chance airsoft, do you? I've also been looking for someone to build a decent speedloader for even longer.
What's funny is the speedloader is the first thing I thought of when I got onto this site lol. Maybe I should try it out >.>
I still have yet to see one that works very well and stores a decent amount of BBs. If you could finally accomplish it, I'd be in your debt.
Here you go. It's basic, as I did it quickly, but it gets the point across as well as anything made of K'nex will for such purposes. I even gave it your favorite feature- a block trigger, just for you :D if you want a better look then I'll post a photo 'ible, but it's kinda lame so...yeah. Stores like...75-100 or so, but can be expanded to hold like 500 lol.
So it's more like a dispenser than a speedloader? Neat, but I need something to force bbs into a magazine rapidly that feeds reliably. That's the tricky part. I made one some time ago that had the loading and feeding of BBs down, but it wasn't easy to align it with the magazine so it just spat them out really. I would've improved it but it didn't hold that many either so I was hoping someone had a better design. However, I think you're onto something. Maybe make a pressure sensitive blocker that you force bbs through.
Derp, they need force? Well then, lol. The magazine on mine lets you draw the spring down and pour them in, so I kinda went off of that >.> back to the drawing board, I suppose. And you see, the alignment problem is unavoidable with knex for the most part, because the smallest thing you're going to put a bb through is a grey clip, which doesn't exactly align properly.
Well if they didn't, I'd just use a bottle with a spout to pour them in... The kind of magazines I'm concerned about are the ones that require loading tubes with a rod to ram them in. And I realize you can't properly align them with the pieces there are, I'm thinking I could probably tape a pen tube section onto the end of one to fix that. Now I'm just looking for the most effective storage possible and a reliable loading system.
Here you go. It's crude, the pressure system is scrapped because it didn't work well when tested with speedloading a clip and it can get a bit tough to pump sometimes, but it's like 20 pieces and holds around 65 BB's(more if you're willing to shake harder and jam the loader a lot). It's a good start, it can be expanded to red rod size and beats the hell out of everything else on the site, in my opinion. I could post it if you'd like. It needs a bit of work, but it's a foundation nonetheless.
Oops, forgot to respond. I now realize that whole pushing system, and I'm very near done. I'm trying to make it as reliable as possible while keeping space open in it. It's got the pressure release as well, so this is actually very likely. As for the storage, I'd recommend what I made- it holds a large amount while using very few pieces and being quite sturdy.
I used to airsoft, and I haven't quite started a new project yet so I guess I'll go for it right now. I'm really bored lol.
KnexFreek (author)  TheDunkis4 years ago
haha thanks. uhm well would the knex dispenser like take coins or do you mean you just turn a handle for a piece. i could do that but it would be alot of work to design the mech for each different piece. cause each piece is a different size and shape. also i dont, but i might work on it. i know how they work.
Sorry, very late reply, didn't notice that I didn't reply until now, here's my idea, just make like a magazine for connectors, something that fits them all horizontal so that the bottom piece will be laying flat for sure. Then use a button or lever to push the piece out kind of like a really weak semi auto gun. For rods, you could do the same but use a hopper. The result will probably be something really big, but if you could dress it up so it look like one clean device instead of a bunch of random containers all attached to each others, that'd be cool. Also, maybe if you want to make it cylindrical and give it the ability to rotate? That might save some space and add extra cool factor. If you want to make a separate one for rods and another one for connectors, that's understandable.
Maybe press a button and a set quantity comes out? Might have to store them in seperate tubes (combine with that connector sorter?)
I would probably attempt the knex dispenser idea if I had enough pieces... why don't you try TD?
Because I don't have the pieces nor the patience.
nebih TheDunkis4 years ago
i have one set of knex and they are for a knex coaster so i have the least ammout considering i have only 1 white connecter...
Meh, you have more pieces than me at least... I still think you should try.
i will be very greatful

No we are definitely still doing the collab. I always post a slideshow before i post, then i post the ible with improvements. In this case, it will have a locking safe it will stand 3-4 feet tall and have a spiral gumball drop to the bottom :)

i hope you have the pieces!

We should start soon !!!!
Well looks like you can't anymore...
Well you are never on any more, so he probably gave up.

Really great job but ..Can you explain me how you got a perfect rating of 5 with 50 votes ? Secondly why my vote of 4.50 has no effects on your rating, its mathematicly impossible ?, anyway your instructable is really great.
KnexFreek (author)  ronalMF4 years ago
thankyou very much!
its pretty easy! almost my instructables have 5 stars! at a certain point when you have enough perfect 5 star ratings things like rating 4 and 4.5 stars have little to no effect. try rating it 1/2 a star to see it go down, but then rate it back to 4.5 :)

the amount of votes doesnt nessecarily determine the rating.
when i had around 10-12 ratings yesterday, it was at 5 stars.

but when you have tons of ratings (like if there were 500 ratings) then it almost woulnt matter what your rating was because its 500 votes to 1
or in this case 50-1
