The following is taken from our project proposal:

1.2 Card Flipping

When dealing a game of blackjack, some cards need to be face-up and some face-down. When a card is dispensed from the deck housing is lying facedown and can be allowed to slide down a ramp and onto the table. So far we have thought of two different systems for flipping the card face-up before placing it on the table.

Figure 6: Flipping Method #1

The first method uses a foot that is lifted up by a small solenoid at the end to the ramp to prevent the card from falling onto the table. Then, a second solenoid pushes the top of the ramp while it pivots at the base. The foot will be an acute angle to hold the card in the ramp until it has been completely overturned.

Figure 7: Flipping Method #2

The second method uses a light sensor near the bottom of the ramp to trigger a solenoid at the top of the ramp, so that when the bottom of the card covers the sensor, the solenoid quickly pushed the top of the card out, flipping it in the air. A bar attached to the solenoid would ensure it flips the way we want. A light sensor makes most sense as a touch sensor might not be sensitive enough to feel something as light as a card.
