[MOC] Card Dealing Machine

[thebricky]

Hello guys,

I have made a fun project which is playing card dealing machine, for this I have used a programmable Lego HUB, two medium Lego motors and different Lego Technic elements. One of the motors rotate platform in both direction and the other throw the cards as programmed with Lego HUB, It works better than i expected.

Very nice. I'm still in awe of this project

But you know - there is a subtle difference: Destroying stuff vs playing cards.

I like to play cards. And simply leave the other stuff to other people.

@thebricky: Wonderful machine/mechanism you created. My family likes to play "Schwimmen" (bloody Germans), where you need "a set" of three cards for each player + 2 "sets" for the one who gives. This is a perfect solution for forking out the cards without claiming ... cheating

All the best,
Thorsten

Cool machine. It is even pretty simple technically, but works great. 

How much it took to do programming?

This is so cool! Great job - keep 'em coming.

Thank you, i have played ''Doppelkopf,, with friends, the rules were too complex :)

Thanks, I usually prefer simplified solutions, without making it too complicated. The programming didn't take too long, about  an hour. 

Programming  the motor below to rotate the platform left and right at certain angles, which was relatively simple. 

To throw the cards, i firstly measured the vertical length of the card (89mm) and the circumference of the wheel (132mm), then I found the number of revolutions of the tire required to throw a card to be about (89mm/132mm≌0.7).

As the last step to find out how many degrees the top motor should rotate, I did a gear ratio calculation based on 0.7, i left the rest to Mindstorms blocks :)

Thanks, I'll try to continue when I have time.
