So, you have a humongous place, and you have nothing to do with it. You're thinking of a specific function, but have no idea if you can do it or not. In both cases, you are in luck! This is a list of all Contraptions and Contrivances found by Trex.^{1) 2)}

If you have absolutely no idea how to use the following contraptions and contrivances, please see this helpful guide.

Also, you might be interested in knowing that – right now – the chance of finding an item is programmed to be exactly the same for each item. Apparent differences are due to statistical fluctuations (and perhaps flaws in the randomness of the random number generator). This may change in the future.

The Robots have set up a Scrapyard Market that will let you sell the items you don't want for Scrapyard Points, and buy the items you do want.

A Contraption that takes a Memento from the player and puts it in the Place's Inventory.

Some caveats:

• To avoid taking a Memento every time the player reloads the page, you must perform a check before firing this Contraption! For example, set a Memory when you take this Memento and then check against that Memory before taking the Memento again.
• You can only select Mementos to take that you've made yourself, but you can set a Memento here and then give this item to another Place owner for them to use.
• This Contraption serves a dual purpose as a Contrivance. If the Contraption successfully takes the Memento, then it acts as a 'passed' Contrivance, like all other Contraptions. However, if the player doesn't have the specified Memento, then it acts like a 'failed' Contrivance. Therefore, if you place this on a row all on its own, and put a Show Page Contraption beneath it, set to show a page with text like 'You drop your Memento down a hole in the floor,' then that message will only be shown if the player actually does lose their Memento.

A Contraption that dispenses a Memento from the Place's Inventory.

With the advent of the Flow Control Knob, the Contrivances which checked for the lack of something were rendered obsolete and removed from the ScrapYard. However, they still needed to be kept around so the programs which use them don't break. Feel free to catalog them below.
