A combination of parts cases, long thin shelf bins, totes, boxes, and shelves, along with a label maker and many rolls of tape. Start by gathering like things, and labeling the box. When a box is over full, split it into two dissimilar groups, and re-label them both. Eventually, everything is somewhere, in cases. Arrange those cases in a way that makes some sense.

Every few weeks to few months, go through each bin to relocate items which have walked. At least once a year, identify bins which are over-full or under-full and restock, combine, or split bins as needed, and RE-LABEL. Don't so much try to get this right the first time, as to get close and make it a little better each pass.

Throw out broken things. If you have a tote or other storage place for each project which is under way, be sure to purge this tote/place at the end or abandonment of the project. If it's a continuing project (e.g. our air cannon), go through it every few weeks to return tools and generic parts to their proper places.

It's not the best solution ever, and we certainly aren't the most organized team out there, but since we've started doing this, things have improved greatly.
