Shitty Ask Lemmy

pour the entire mix over a coat rack or similar assembly of hooks. this will remove any looped snacks

You can make a tray with holes slightly bigger than a pretzel piece and shake everything through the holes. What stays is everything bigger than the pretzel but all the pretzels and smaller go to a lower tray.

Then in the lower tray you have holes slightly smaller then the pretzel and you shake everything through.

Then everything smaller than the pretzel is on the bottom tray, combine that with the top tray and you've got yourself a prezelless snack mix.

Buy the individual compenents- the little corn chip rings, Cheetos crunchy and chex mix and mix them together.

If you're feeling really ambitious then also get pretzels and mix in so that you can use the other commenter's Arduino Lego contraption to remove them.

Snap a picture for each one and upload it, along with a question “Is this a pretzel?”

Parse the answer and route the conveyor accordingly

Presto. Probably about $5 and one hour or so for each bag you want to sort. What’s not to like.
