Description:
A box of miscellaneous objects, including:
- 13 screws, of various lengths, thicknesses and colors
- 7 binding posts, 6 of which have threaded rods underneath them which can be screwed in anywhere
- 2 circular washers
- A black cylinder with brass top and bottom
- A metal half-hemisphere with a threaded rod running through the middle of the inside
- A larger device made up of a rectangular metal base with a circular hole in the center. Directly under the hole a tiny slotted screw is threaded into the long side of the rectangle. From the other long end of the rectangle, a tall metal pole rises from each end. Between these two poles is a rounded black diamond-shaped component (perhaps a spool for a coil?). From this part spring two stray wires.
- Four metal pieces. All are made of a number of brass parts joined together, and all have mostly sharp angles. Some have small metal discs (perhaps they are knobs?).
