I am trying to build (3d print mostly everything) a true random card shuffler. like the ones that are under the tables in the casino.The plan is like this (viewed from top, my wheel will be laying down instead of standing up like in the video)Everything will be controlled by an Arduino.It should consist of a big wheel with 52 slots of cards. cards will be fed one by one from the deck into the wheel. After all cards are fed. A random order will be generated with which the cards will be thrown out of the wheel on the other side one by one.throwing out the cards will be easy, there will be a servo with a specifically shaped plastic piece that will come up and down from beneath the wheel through its middle.feeding the cards into the wheel one by one is something Im not sure if I am planning correctly.Im thinking about two options of feeding as drawn.Option A: Cards are staying in a casing that on the left side there is a slit that should allow only one card to pass. A pusher wheel coated with rubber or foam should spin and push one card through the slit, the sensor is there to know when a card fully passed to the big wheel (entered the sensor and then exited the sensor). Then the pusher wheel stops and waits for the big wheel to bring the next empty spot.Option B: Because the card might not go all the way in to the big wheel, Im thinking maybe put another “feeder wheel” that will constantly spin much faster so the cards will actually be forcefully thrown to the big wheel. The “pusher wheel” will just feed one card slowly to the “feeder wheel” to be picked up by it.Sorry if this might be the wrong subreddit, but Im thinking there are imaginative and helpful people here that might help.What do you think about my two options? Do you have a different approach to feeding the cards? Do you have a totally different approach into all this thing?I am trying to keep this whole thing as simple as possible but also reliable as much as possible so that cards wont get stuck or two picked up at the same time, etc… Also want to be able to print most of the stuff.Thanks a lot. http://ift.tt/2atR3cX
