Slicing the apples can be done with a sharp knife and a steady hand - or, you can use a mandoline. A mandoline is a handy kitchen tool that creates very even, thin slices. They range from basic to deluxe and are priced accordingly. Look for one that is easily washable and has the features you're seeking - basic slicing is sufficient for your cooking needs, or are you going to use crinkle cuts and dicing?
For the apple chips, simply rinse off the apples and slice quite thinly. You can dunk them in a solution of water and lemon juice if you wish - this will slow browning. Place them onto a cookie sheet (I lined mine with parchment paper), sprinkle with ground cinnamon and bake in a 225 for an hour and then flip the apple slices. Bake for another hour or so. They won't be completely crispy until they've cooled.
Not crispy enough? Pop 'em back in the oven! Exact times depends on how thick or thin the slices are and the apple variety, as well as your personal preference - some folks like them to be more leathery and others prefer a crisp chip. You're the boss!
