Electronics Room

From i3Detroit
Jump to: navigation, search


The gray and gray/yellow drawers on the back wall are the electronics store. These components are for sale to anyone who has a use for them. Place payment in the drawer labeled with bold dollar signs and the word "payment" near the lower right.

If you don't know what a component costs, find it on http://mouser.com/ and add 10% to cover shipping. If you need change, you can make it with funds from the soda payment cup in the fridge. However, these funds go to different people, so don't just drop money in the wrong cup.

Some members may have components or salvageable parts that they will share but which may not be part of the electronics store. Use your judgment when taking those things.

If you wish to donate components to the store, feel free to do so. If it is clear where they should belong, just drop them in. Avoid placing them in an unlabeled drawer or bin. If you don't know where something belongs, ask Nate B, or leave a note indicating your intent and he will find or make a place so the parts can remain organized.


As with all of i3, leave nothing on the workbenches. The only thing permissible to leave on a workbench is the Edsyn soldering station and the tip cleaner. Your project can be stored in a labeled box in the electronics room if you are actively working on it and it is small. Otherwise, take it home or use a larger member storage area in the shop area.

If you were trimming or stripping wires, consider sweeping before you leave.


Parts on this list will be ordered ASAP.
