This can also be used to put the cards back into the box in the correct order when you are done playing!

Your KZfaq channel is very underrated. Glad I stumbled upon it today!

Great video. Now really convinced me that casinos is stealing my money right my very eyes with the "shuffles".

It might raise some suspicions when it takes 5 minutes to "shuffle" the deck. Really cool project though.

The amount of system integration work that you're able to make work reliably is amazing. Amazing work.

it's so nice when the youtube algorithm coughs up something I'm interested in watching. Apparently herring bone gears can be quieter.

Silicone lubricant man, should help a fair bit with the noise in the gears.

Add a "sort" mode as well, for people that wanna get an organized deck on demand. :)

“I’ll see yah in a few more years” 😂😂 gosh I hope not. Amazing video Andrew! This channel is one of my favorites and I can’t wait to see what you do next!

Dude you need to keep it up. This was amazing. I just watched the whole thing without blinking.

Welcome back! You should update the software to inform you if any cards are missing.

Evil! Subbed. Two ideas. First for the feeder, have a look at how printers run their rollers. They almost invariably have three: pick, feed, and separation. On cheaper machines the sep roller is just a pad. Anyways ideally the pick roller (the one that sits on the stack of paper) rotates along with the feed roller, and the sep roller is either stationary or even turning slightly backwards. That's what prevents double feeds. The pick and feed rollers are usually on sprag clutches so they can freewheel. After those three, you'll have two driven pinch rollers that actually deliver the paper. Second...there should be an even more evil and harder to detect algo in the evil shuffler: make player x really lucky. Don't specify any one hand, just make sure that x always has a better hand than everyone else. Maybe they'd even occasionally lose a hand just so nobody gets suspicious.

Nice that it can start from an unordered deck with card recognition; quite a project! In some competitions (bridge, for instance) all tables need to play the exact same hands. They use devices to create a series of identical decks. But building your own is of couse way more satisfying, and a nice project indeed!

Just discovered this channel now through the video. Impressive. Liked and subscribed.

This is a great project and video! Glad I found this channel. You could maybe add a physical button on the device itself to do the regular random shuffle so that mode can be used without having to open up a browser (if that's the most common use I mean haha)

And of course, there is in fact a method to prevent just this kind of deck ordering shenanigans: The Cut.

Hi, great vid. Just had an idea for the dispenser to make it more reliable. Where you have the pair of rollers spitting the cards out, the top one could briefly rotate in the opposite direction, so if there is a second card on top it gets put back in the deck while the bottom one continues but if there is just one card it will get sucked slightly in then spat back out again. Alternate idea, put the roller on a moving arm that goes on top of the deck so it only pushes the topmost card out at a time, if you springload the arm so the downwards force (and move the tray up a bit for each card dispensed) is minimal the top card wont have enough friction with the one under it to drag it along. Have the arm mechanized to move out of the way (idk with a servo or something) so when the shuffled cards are being inserted it can get out of the way.

Bro, did you consider tagging your video under the section of 'horror' ..This is the stuff that fuels nightmares. These casino machines will flat out put people in the streets.

What fun you had creating this! Here's something you might like to add.... a "Pack Sorted by suit" with choices of how you want the pack sorted... Ace-King (or reverse?) but so you can pick Spades/Diamonds/Clubs/Hearts or any combination of the suits?

Nice to see you back. Hope you are doing well.

Well shot, well edited, well narrated, straight to the point with enough information it's interesting but not too much that it gets boring or confusing. Oh, also a great idea that was executed well Amazing work, instantly subscribed at the end of the video!

Love the video! But there is a cut by the dealer once it's done. There are even ways to set up the deck where cutting it anywhere will still result in a rigged result.

Me: I wonder if I could make a card shuffler that stacks the deck... KZfaq: Here you go

This could be modified for "tele-IRL card playing" i bet (pun?). Kind of like what @Stuff Made Here did for the automatic pool stick?

This absolutely is what shufflemaster patent shows. Great video and great work showing us. This is definetly what the casinos do. I miss the good old hand shufflers now they say most states banned hand shufflers. No its banned bc they want more $$

I'm late to this party, but I think the mechanics can be simplified quite a bit. The movement of the dispenser could replace the movement of the slots module - The slots module doesn't have to move at all and the ejection bar for the slots module can unload all of the slots at once if the dispenser is at the very bottom. This would make the sorting mechanism quicker and would allow you to fit more slots in. If the dispenser was double sided you could have slots on both sides as well, allowing even more slots within a compact space.

underrated channel !

Sidenote, that paper feeder will be of use with some OS Plotter/inkjet printer development !

Great project. And the reason that most state gaming regulations required all cards to hand cut is to disable any chance that an ASM can be hacked and used to cheat.

Just FYI....most companies that create shufflers don't sell their products not because of hacking but rather their model of business is based on leasing their products to casinos. They would much rather keep getting a monthly paycheck from the casino in using their machines than a one-off payment (not enough casinos open up each week for them to profit off of). The lease has stipulations that the casino has to adhere to or lose possible millions in lawsuits, this allows the shuffle companies to control all aspects of their units. You don't get access because you are not a casino....and contracts are usually set in years and numbers (such as 5 machines at $25,000 per month for 1 year, as an example). There is no "hacking" because unloading data requires a password authentication and a hardware key, otherwise you are physically hacking which can easily be caught by casino managers and surveillance. The software has several modes based on the number of games the casino provides, allowing a machine to be swapped from table to table as needed.....and it also has a sorting and recall function. Despite what conspiracies are out there, no, the machines do not have a "set hand" function as not only would that violate commission rules, but also leaves a vulnerability for casino losses by the shuffle company (which leaves them liable on those losses because the code is theirs by lease). Yes, the machine can sort and recall, but that's just reading, not setting. Just a little FYI

Make an algorithm that makes the interface more simple. Like: which player will win and then it just makes a random situation in which that player will win. Also, you could add a little slide thingy to the end which can rotate. This then automatically distributes the cards to the different players / to the middle. You could add so many cool features in the code.

Good to see you back. This is honestly a pretty cool and involved project.

This: is in my recommended Me: is not disappointed in the algorithm

Brilliant work! Congrats on nailing it!

Nice recreation of what we did in the mid 70's (OCR and handler not cards but the concept is the same) Personally I believe the rotary storage is a better method, but that is my opinion When you see the shuffle master sort the cards the first time this should tell you they have full control

You know, when I was a kid, I made a card shuffler (which worked quite well) out of legos. the wheels are perfect for dispensing cards

OK now I can get into agriculture! :D Amazing work, bud!

Hello stranger! Glad to see you’re still with us!

Love the content Andrew! I vote you make a video showing off your process for building super simple 1-pager GUIs for python with HTML and PMP.

Given the ability to set the deck order, and read the deck order, you could actually shuffle in software, and then just build the deck to that shuffle. No need to run through excess shuffles. I'm guessing only 2 would be necessary.

This is pretty fantastic. It would be fun for, say, having two identically shuffled decks and see who does better at Klondike.

You spend two years working on this to finally beat your friends at poker. Then the dealer takes the cards from the machine and cuts them.

This is a very impressive machine that goes well beyond the scope of anything I desire from a shuffler. However I hope you can push me in the right direction, I'm playing a board game called Talisman which has several decks containing hundreds of cards, with the main "Adventure Deck" being over 600 cards with all the expansions and is a tedious pain to set up. I'm looking for a shuffler that can shuffle US Mini sized cards and won't destroy them either. I've seen some of the demos of the cheap mass produced shufflers and they look like they'd wreck these cards. Manual hand cranked versions seem more viable but they would still take too long and don't seem to provide a good shuffle judging from some videos I've seen. Apologies if this was impertinent to ask but I'm at my wits end trying to find something good that won't break the bank and your video came up in the results.

Damn, I didn't even realize I was subbed to you, bought a 3up kit wayyyy back when. Cool project!

Bro , this person built this.. now all the casinos have “automatic shuffling shoes” casinos probably spent millions to develop AI technology to use against us

guaranteed Vegas has been done had this technology

5:40 Making a "code explanation video for NERDS" video or something similar for projects may allow for moar youtube treadmill/algorhythm feeding, as well as helping others learn how to do the "behind the scenes" (granted may be other sources to learn obviously, but moar videos/content = moar win?) (also would require NLVE-ing time which is ...eh (at least for me) so may not be worth it in your opinion, just throwing this idea out there)

Amazing invention ...First time to your channel...You mastered 3D printing, engineering, and coding to create this machine...Bravo.... Imagine what the big casinos are investing in, to gain advantage over players... Do the Shufflemaster one or two models have software/cameras to detect suits in pokers games??? I've been playing for years and been witnessing some extremely suspect hands by dealers..

THIS WOULD BE A FUN PRANK WITH YOUR FRIENDS!!!

This is super cool project! Nicely done

I've stopped playing cards....

you could greatly decrease deck restoration time by pushing the bottom 4 then the top 4

How does this channel only have 24k subscribers???

Can’t wait to see the Uno version

How about if the dealer is required to cut the deck? It makes it 1000x more complicated.. The only way to assure player x wins the pot out of a 9 player Texas Hold'em table, (without the dealer who cuts the cards knowing) is to fix the deck so that 52 combinations all having the same player winning. No matter what point in the deck u start from. Since there are a millions of possible combos, u can easily write a script of code that will make the player u wish to win, win every hand or every other hand to not make it obvious. You just need to tell the computer exactly how many players will be dealt in, and it could be done seamlessly.

great job ! you are quite a inventor! I am thinking of making a simpler version - the one that will just shuffle cards randomly into 4 stacks; no need to recognize cards etc.

OCD can be emulated by comparing all master images with the scanned one and take the one with the highest % score. It's not how OCD works, but it's a lot faster.

that's a really cool shuffler. i have one of those cheap noisy ones. lol i barley used it. i was tying to make a card distributor or electric dealer 12 years ago and instead made a device that throws an entire deck around the room in a matter of a few seconds. it was too fun to fix.

How about the shuffle machine Texas Holdem when playing against other players?

I love these kinds of projects and videos. Keep it up, subbed!

I appreciate your oxford comma.

I want this. Actually what really got me looking was less poker, as its easy to shuffle for poker with some practice, but there are so many board and card games with even larger decks and cards that I want to sleeve, that decks become difficult to shuffle, and it would be great to have something with a bigger hopper that could shuffle up large decks while the rest of a game is being setup.

Thank you, a lot, for showing and explaining this. Very useful. And amazing great work you did, well done!

Lesson Learnt...Never ever play to the casino in which machine shuffle has been done.....always play on the table on which Manual shuffling has been done by Hand.....Am I right Sir ???...

Amazing! take a look at the paper pickup mechanism on consumer printers, it might give you some inspiration on how to improve the card dispenser

Bro, have I have an ad blocker and you are the only channel that I turn it off on

I feel like the image recognition part can be done a lot faster with a tiny AI model that can run on raspberrypis.

feels good to be a new memver

Nice project!

Hoping to see v2 of this soon!

Super Cool! Most of the issues you were having with the cards, the biggest one being able to get a single card, I would have to say were the cards. Bicycle cards are great cards, but if you were to use them at a NLTH tournament, they would last about 10 hands max. If you had some plastic poker cards, the Copag Poker Jumbo are great around $10/pack, the cards would become a constant, not a variable. They would always be, and only be, as slick as when you begin, unlike the Bicycle which would start one way and continuously change with use. I really want one, but dont think Im at this level yet.

2:14 Wrong payout. Cat gets 3:2 on blackjack at a good casino. 😺😺

the dispenser would colloquially be called a " shoe " in theory , you could have a realistic 1 , 2 , 3 deck-shoe game of blackjack - which was invented to stop card counting , the more decks in the shoe, the harder they are to count

I can’t imagine the time and effort. Wow!

You shorted your cat on that blackjack.

11100% would buy this if it were available. Just for the proper shuffling capabilities for our weekly poker game

i had a friend who had a cheapo shuffler. you split the deck in 2 parts and it would shove the cards randomly from each pile in the center, do it a few times and it would be shuffled

5:39 When the sreen turned black I thought my PC crashed

Due to strong interest in this project (and wanting to recreate it) I did some research calculations. I found that with 8 bins the chance of the bottom card ending on top is about 790x larger than the top card ending on top. This quickly decreases to 2.3 times after 2 shuffles and to 1.1 (neglectable) after 3 shuffles. I thought these results might be interesting ; ) I hope it's OK to use this concept for inspiration for a future design project of mine.

*Casinos Everywhere are Sweating*

Every engineering channel on KZfaq: I found a reasonable version online but “didn’t want to spend the money”, so I spent 10-100x (Stuff made here) the cost using my own time to create a super specialized, cool version that has little to no practical application. Or to put it another way: it’s fun to make shit. I suffer from this too. Getting ready to launch a Kickstarter myself.

maybe add a button so you can just press it to start the machine with previous config

After doing the normal legit shuffle, the first seven visible cards are all hearts. That seems highly improbable

I’m sure casino use these type of programs to increase house favors. There are many CC trying to reject this idea it’s absurd

It looks like the image processing is taking way longer than your mechanics can handle. (@11:34 you can see the shuffler just waiting.) It's worth looking into some form of faster computing.

Annnndddd now the Casinos want your product.

This is a StuffMadeHere level project, why doesn't it have more views?

SO IF HE BUILT THIS SHUFFLER WIT 100 DOLLARS IMAGINE THE TECHNOLOGY THE CASINOS CAN PAY FOR?? THIS REALLY EXPLAINED IT ALL

I know you said you had no interest in making these, but let me try and convince you otherwise. Machines like this, with the same capabilities run between $12-15k new, $4-8k refurbished. Let’s say at scale you could keep your cost to $200-300 . I would be willing to pay $2.5-3k for a shuffler like this. All you need is a little refinement, a case and a UX .... could be just buttons or a whole separate small LCD like the Shufflemaster Deckmate II. I’m telling you there is a huge market for something like this for weekly poker nights.

Poker hands would be harder to rig, because the dealer must cut the cards after retrieving it from the machine. So the dealer would have to be in on it and either do a false or precise cut to get the desired order of cards. Or the programmer rigging the hand would have to guesstimate where they think the dealer will cut cards.

This is seriously so awesome

You should add a unshuffle option to put it back into the order of a new deck!

You're a genius...

You should try using dielectric grease for the noise. It should help out a bit

I know I'm like 10 months late, but build it into a poker table.

Lol so your first idea is basically what I wanted to do to shuffle MTG commander decks Almost identical (except I was planning on using another wheel to push them off to the sides) Edit: though i think the pusher is probably better and faster, might be harder to split the deck evenly in 2 though

Everyone says lube for the gears. Sounds crazy but anti-seize works amazing for 3D prints it helps to wear in the gears with the sand in it.

Man, the casino stuff I learned!

6:20 Ahhhh please don't leave the sticky like that
