Introduction
Component drawers with useful stuff - these can be found on the wall next to the electronics bench. This is intended for stuff that's too awesome to keep to yourself, but too expensive to just give away.
Parts can be taken without asking, but please leave money in the drawer you took the part from. Please also keep this wiki page up to date. When adding new stuff it is helpful if you can include a link to the datasheet.
Draw numbers are [row][column], with 0A in the top left
