Introduction: Knex Automatic Card Shuffler

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

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

  • 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)

Step 2: Shuffler Base- Part 1

This is the first part of the shuffler, this is the part where you insert the cards.

Follow all of the notes on the pictures.

Step 3: Shuffler Middle- Part 2

This is the second part of the shuffler.

Follow all of the notes on the pictures.

Step 4: Shuffler Middle- Part 3

This is the third part of the shuffler.

Follow all of the notes on the pictures.

Step 5: Shuffler Middle- Part 4

This is the fourth part of the shuffler. A bit of a short step...

Follow all of the notes on the pictures.

Step 6: Shuffler Top- Part 5

This is a top section that will go onto the back of the shuffler.

Step 7: Other Details- Part 6

In this step, you'll make the things that the cards will slide on when they are emptied into the tray. Then you'll make the card pusher.

Step 8: Shuffler Top- Part 7

This top section will complete the look of the top. Also, you'll build the battery pack holder.

Step 9: The Motor- Part 8

Here is the part that will make it all automated: the motor!

I'm sorry about this step, but it is all in one clump. It was too fiddly to take apart, but there are loads of pictures!

Step 10: Attaching the Shuffler and the Motor

Here you'll attach the motor to the shuffler and connect the battery pack.

Step 11: Other Parts-Part 11

Now you'll build a bottom section and fix up the rubber bands.

Step 12: Card Tray-Part 12

This is the tray that will hold the shuffled cards.

Step 13: The Other Shuffler

This is the other shuffler, just repeat steps 2-8, but do not add the battery pack holder as the other one.

Follow the notes on the pictures! :-)

The second picture is what it should look like.

Step 14: Connecting the Other Shuffler

Attach the other shuffler to your model. Make sure the rubber bands are fixed up right.

Step 15: Finished!

Congrats, you are now finished with our awesome card shuffler!

All you have to do to shuffle them is cut the deck in half, insert each half into the two sides, turn the motor on, and watch the cards get shuffled.

Have fun shuffling cards!

You might have to put the cards in two times to get them totally shuffled, but nice machine. 4.7*

willowbramwell made it!(author)2016-02-17

What I think i might try is to have two motors of different speeds so that the card shuffling is less predictable

12mokeef made it!(author)2016-01-04

please help the wheel inside seems to be just going gently over the cards, and not moving them please help :-)

knexfun101 made it!(author)2015-05-12

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

Lolman4000 made it!(author)2015-04-11

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!

Lolman4000 made it!(author)2015-04-10

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!

A two year old would be able to spell it properly.
Grammar wins!
Stupid 10 year old FAILS!

harry+potter+rules made it!(author)2011-01-20

NatNoBrains made it!(author)2011-01-20

Just because you can't spell.

harry+potter+rules made it!(author)2011-01-21

NatNoBrains made it!(author)2011-01-21

Don't forget full stop and capital letters. Also it's 'that's' not 'thats'.

PINKmonster325 made it!(author)2011-09-04

Wow, this is funny.

RyShark made it!(author)2010-06-27

Can you do this with the plain green motor?

Hiyadudez made it!(author)2010-06-27

Possibly, but you will have to modify it.

brainiac120 made it!(author)2011-05-13

I did it worked fine

Orange+Oz made it!(author)2010-08-19

Tornado96 made it!(author)2011-03-16

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 made it!(author)2011-03-16

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.

Tornado96 made it!(author)2011-03-16

Didn't he? I TOLD HIM TO! >:-( Ignorant brother...

It did work though! thanks!

BTW I'm pretty sure he's giving credit so..
