Hey guys, we're back! Yes, me and Shadowman39 are back with, yet another, awesome ible!

 PS-If you subscribe to me, subscribe to Shadowman39 too. :-)

This time we decided to build a card shuffler. This neat gadget will shuffle your cards for you, so you won't have to do it. And, it's all motorized. It will fit any standard-sized poker or playing cards, so anyone can have one.

So, you likey? Of couse you do! Now move on to the next step to build it! If you don't want to, then... build it anyway. :-P

Edit: this has reached 4.50*!     ---     Thanks to everyone who rated! :-D

Shadowman39 worked hard on this video. :-D Here's the card shuffler in action:

Step 1: Parts List

Picture of Parts List

Here's all of the pieces you'll need to build the card shuffler.

Rods: 261

  • green-149
  • white-79
  • blue-16
  • yellow-6
  • red-11
  • gray-0

Connectors: 178

  • dark gray-31
  • light gray-6
  • red-18
  • green-5
  • yellow-18
  • white-24
  • orange-8
  • blue-15
  • purple-53

Other: 106

  • small wheel-8
  • small tire-4
  • blue spacer-33*
  • silver spacer-24*
  • tan clip-10
  • blue clip-6
  • Y connector-16
  • thick-ish rubber band-2
  • thin rubber band-2

Total: 545

And, there's no point in building a card shuffler if you don't have any cards, so get some! :-)

*Numbers may vary.

So, if you have all of these pieces, then let's shuffle on!  (pun intended... hehe)

do you have to use that kind of motor?
I made it with the blue motor and it works just fine. See.

What if I don't have that moter? can I just use a green one?

Lolman40004 months ago

I made it! I had to mod it a little so I could use the blue motor. It works great with certain types of cards!

This is a great inspiration! I didn't have enough green rods, so I left some out in certain places. My only problem is that the cards come out one at a time like they're supposed to, but both sides come out at the same time, colliding in the middle and not forming a single pack. Do you know how I could fix this? Thanks!

do you use like those thick knex sticks or those thin ones?
The thick ones.

this is aamazing! i made it and i added two elastic bands to the things that hold the cards down because it sometimes stops feeding the cards, but its probly just my cards. thanks!

Can you do this with the plain green motor?
Hiyadudez (author)  RyShark5 years ago
Possibly, but you will have to modify it.
I did it worked fine
it worked for me!

My brother is trying to use this for a science project at his school and he ran into a problem. The cards don't come out flowingly. ! comes out and then the rest come out in a pile. Any idea why he's having the problems?
Hiyadudez (author)  Tornado964 years ago
Get looser rubber bands on the paddle things. Tell me if that works.

Even though anyone can use this, it would've been nice if he, or you'd have asked before just using it.
Didn't he? I TOLD HIM TO! >:-( Ignorant brother...

It did work though! thanks!

BTW I'm pretty sure he's giving credit so..
can u make a smaller version that only uses 100 pieces :]
i was talking to hiyadudez and shadowman39
Then send it as a PM.
But there's only one of you.
by sos i meant sorry

You should be.

We're busy at the moment, but you can try to build one.

4.46. :-)
knexjay5 years ago
This is simply amazing. It functions great and never fails, the only defect is the speed. Is there any way to make it go faster? If there is pleaste post on how to. The instructions were also great too because you got all parts from every angle so I finished this project extremely fast! Great Job guys!
Thanks! If it goes faster, it doesn't shuffle the cards well at all, and they get jammed up.
how does instructable notice, that you are a auther, even thougt Hiadudez postet this instructable?
I'm a collaborator, so it puts my name up there.
I modified mine so it will shuffle better, you have to mod the spinner and gear mechanism and btw I get wat u mean I 4got I modded mine lol
Sorunome4 years ago
Awsome (tell if I spelled it correctly) 5*
Thanks! And it's spelled "awesome". :-)
oh... :(
Use spell check, it helps a lot.
I just have a german spellcheck!
Lol, go into an options menu on your browser and try to change it to English.
1. I don't know how to do it with firefox
2. The whole spellcheck of firefox would be english, but i also need german spellcheck!!!
1.) Figure it out.
2.) Use English when you need it, and when you don't, switch it to German.

You Are So Awesome With K'nex!!!!!!!!!!!!!!!!!!!!!!!!!!!! The Best Invention Ive Ever SEEN!!!!!
No Problem, I Finished Making It Yesterday Its AWESOME!!!!!!!!!!!!
Cool, glad you built it!
my mum is so happy now, cos now she can sit back and relax whilst the cards shuffle!
Lol. :-P
hedzup4565 years ago
hey all u people that say it doesnt shuffle well enough, shuffle the cards TWICE(or more)

That took me two whole hours :|

What did?
I thought you left... or is this shadowman?
Hiyadudez (author)  TheFoofinator5 years ago
This is Shadowman.
Hi Shadowman!
Look on his youtube channel, he hasn't sold his knex, in his latest video he has around 3 guns in it!, he just said that he sold it as an excuse to get off the site! Pirate >:-( .This is Hiyadudez I am talking about, and the video in question is anti gravity ramp revealed.
He isn't totally off the site, he posted three forum topics yesterday.

builder9685 years ago
I'm building this because my mom asked me to make it for her. Not only that, but I think it's pretty cool. Finally, a practical use for Knex. Well, besides scaring siblings XD
numro_xi5 years ago
i have found this brillant, although i found it better to add a gearing system, this atleast 1/2's the time it takes for it to shuffel the cards, i allso added an hand leaver which can make it faster, or means you can get a whole deck of cards through with the gearing system. 5/5!!
Hiyadudez (author)  numro_xi5 years ago
Thanks for building! Picture?
well, i believe that i may be getting a camera l8er (GMT) for my birthday today, so it will test its capabilities XD.
It's your birthday on June 16th?
I just made it too, but haven't test it yet. The movie is very cool. I can't wait to test it. Thanks for the instructions. I will post a comment when I have test it.

Well done, looks great! Thjanks for building :-)
5* awesome creation well done
Shadowpom5 years ago
 I only have the crappy blue/green motor will it work?

ps. great idea
It should, but I think those motors go faster than these motors. This shuffler is speed-sensitive.
so let me guess your probably  going to make a printer
Wrong guess. :-P I'm building something else.
 I will try it, and let you know how it turns out.

Very good idea, but it seems like it would only alternate the cards; Shuffling is supposed to randomize the cards, but because I haven't built it I really don't know
It randomizes them alright. ;-)
Jayefuu5 years ago
Fantastic! Get some better gear ratios on those motors so they move faster and I've no doubt it'll get featured :D
Thanks! I tried making it go faster, but the cards don't shuffle well when going faster.
Tornado965 years ago
How is this not featured? I want at least one reason to why it isn't featured!
guy-man5 years ago
when i built it the motor send one half going one way but the other half stays the same did i mess up? please reply!
Yeah, you did. :-P Make sure to fix the rubber bands the right way.
instruct395 years ago
dude this things is so awesome! I gave it a 5* and I shall build when I have time.
For some reason, it wont let me reply on my own comment so i will reoly on yours, i fixed mine and now it works perfectly i give it a 5+
knexfan91825 years ago
The problem with this is that its too consistent.
Wow man, this looks great!! I might even build it. :) 5* and should be featured.
Thanks man! I haven't seen you around in a while. :-)
Hiyadudez (author)  Shadowman395 years ago
I told him to come check it out the other day.
Cool. :-)
 With mods, this could be made into a card gun!
Lol, interesting.
Shadowman395 years ago
For some reason the comments are weird.
Yeah I see that too...
The names are after the post date/time.
really good! 5* edit 4.25* i will most likely build when i have the chance!
RNB5 years ago
I've build this and it works good, after lots of time to find out how the rubber bands must be on it. (if it's wrong English, i'm sorry) It should be a lot easyer to build if there was a photo from the figure 8 rubber band. 
knektek5 years ago
looking at your video, i would suggest getting a larger load on the motor. In other words, instead of using a pair of 1.5v cells, use a 9v battery. to make it run faster. One reason for this is i could shuffle cards in 5 seconds.
It doesn't work as well when it runs faster.
Hiyadudez (author)  knektek5 years ago
I bet you can shuffler cards in 5 seconds, but that just dea=feats the whole object of a card shuffler.

I'd like to see you do better.
MegaMetal85 years ago
here he is
it works really well
(even with the quick motor)

i built it yesterday

is it a boy?
Looks great!
Hiyadudez (author)  MegaMetal85 years ago
Dude that's awesome!

Thanks for building!
i actually found it shuffled quicker and better

but its less reliable then the slower one!
(as selez said)
 Glad to see you are still around
 IT'S TOTALLY AWESOME!!! You two really are an incredible pair. You make loads of cool stuff (all five starred!!!)
Seleziona5 years ago
Hey! I tried using this with a faster motor (the one from the starburst spinner set) and it does deal the cards a lot faster, but it isn't that reliable. Just thought I'd tell you guys this...
Yeah, I had tested it out faster and it didn't work well for me.
Ya, didn't work to well for me either.....
In one word: AWESOME.
In more words:HOW DID YOU GET THAT IDEA???
It's so cool, and it really works.
Hiyadudez (author)  erikos kostarikos5 years ago
In one word: Thanks!
In more words: Shadowman suggested a load of ideas, and I chose card shuffler and made the first prototype, it went on from there.
Thankyou again.
Did he have other cool idea's?

PS. No problem =P.
Hiyadudez (author)  erikos kostarikos5 years ago
Yes, he did have other cool ideas.
kelseymh5 years ago
This is most impressive!  I wish that you K'nex folks could learn to write descriptive text instructions, instead of just image notes.   It's impossible to see any image notes when you print an HTML page, and nobody can use the notes with a screen reader.  The lack of clearly written steps makes it not featureable (in my opinion), but you still get 4.5 stars for the lovely and functional device!

Hiyadudez (author)  kelseymh5 years ago
Bummer. I will get around to writing the steps.

Thanks anyway!
No worries!  Let me know when you've got some descriptive text in the steps, and I'll take another look.  I really do like this project, and it deserves to be presented as well as it can be.
I wrote in more descriptive descriptions into the steps. :-)
Oh, I see.  You've labelled the components; that's helpful!  I had more in mind some text describing how to assemble the components, but I realize that you probably see that as redundant with the pictures themselves.

I see that Staff has already featured this within the K'nex channel, but I think it's worth being featured a bit higher up.
Hiyadudez (author)  kelseymh5 years ago
DO you have the power to feature? o.O
.  Dr. Kelsey has many strange and wonderful powers. Some downright awe-inspiring. Tread lightly.
Thanks! I didn't make that part of the instructions, and I didn't know what to put down since they weren't my pictures.
Hiyadudez (author)  Shadowman395 years ago
Hey man, people are hating already. It has 10 ratings and its only on like 3.5*.
That's not hating, that's loving.  The way the rating system works is that each individual rating is averaged against every rating for every instructable on the site, so you see it drift away from the average (2.95) very, very slowly. 

Take an I'ble with no ratings, and give it five stars.  What shows up?  3.09.  You really need to have dozens of ratings applied to an I'ble before you see the number close to what people have actually given.  If you're already above 3.00, then you're doing extremely well.
Hiyadudez (author)  kelseymh5 years ago
I know, but usually it should be more than 3.5* if it has at least 10 decent ratings.
What do you call "decent"?  The descriptive labels provided by I'bles are pretty clear.  If something is good, it should be getting 3.5 ratings.  If something is really Outstanding (better than most everything in its category), then it deserves 4.5.

There can be only one "Best ever", so getting lots of "five stars" is just the same worthless grade inflation you see in schools these days.

Remember what they say, "If everyone is special, then nobody is."
Shadowman395 years ago
Lol, I almost forgot to favorite this.
well im startin to collect parts and theres rubber bands what types would be what (from left to right #32, #64. and a knex trekker band)
The trekker band is perfect for the belts along the back. The #32 band looks good for the other parts.

Good luck on building it!
love it i got a few pics =D
Looks great, well done!

You 2 are pretty much the knex equivalent of Eric B and Rakim.  Nice job.
Thanks! Are those two people famous rappers or something? Lol.
Lol, I knew it. :-P
Get "Paid in full", that album is awesome.
I would, but I don't listen to rap/hip hop.
Well then go listen to it.

Will build sometime =)
Seleziona5 years ago
One question, can you put any amount of cards in either side??
Thanks! And yes, you can. But I wouldn't put more than 30 in each side. It's meant to shuffle a deck of 52 cards (26 on each side).
Awesome! I'm going to build VERY soon....
Cool, good luck!
BUILDING RIGHT NOW! Should I take a pic when I'm done?
Cool, sure!
Here ya go!

except iv got the quicker motor
ill try with it
brammeke115 years ago
Nice! Fav. You would probably want to send the cards through a couple of times.
 I was wondering... if i modded this a bit  with gears to make it go faster, would it work? like would it shuffle them faster? btw i didnt build it yet.
I tried it faster, and it actually didn't shuffle as well. But you can try it, it may work better for you.
Wow excellent job you guys. 5*s Favorite and Already subbed. I will probably make this because my family plays poker alot.
Hiyadudez (author)  silentassasin215 years ago
Thanks man. We did work hard on it :-P
Your welcome!
lemonie5 years ago
This is really great, slow but it gets the job done. Do you know why it starts of perfect but throws lumps of cards towards the bottom of the decks?

It did that because some of the cards weren't slippery enough (the red cards), and I had tested it out during construction with the more slippery cards (the blue ones). It works better with just blue cards.

Anyways, thanks!
Does the friction vary with deck-thickness? The first few get beautifully shuffled, the end part's not much of a problem if you split and re-shuffle, but it's almost really there.

Yeah, the cards at the beginning are pulled out better. It has to do with the pressure put on top of the deck with the rubber band thing. It also depends on the angles of the decks.
Hiyadudez (author)  lemonie5 years ago
On my card shuffler, it worked fine, You'll have to ask Shadowman. Mine worked fine all the way through.

ANd thanks!
dsman1952765 years ago
Beautiful! I attempted a similar idea a few years back but failed really bad :-).
I like how it picks up one card at a time, not just huge clumps.
Thanks, glad you like it!

sweet 5* already subbed how do i favorite it says i have to be pro

And yes, favoriting is a Pro power. :-)
:( but non pro people have favorites
Hiyadudez (author)  webby4275 years ago
they were old ones
That was probably because they favorited something before Pro existed. It may also have to do with when they joined the site.
