This is a resistive analog joystick, very similar to those found on the PSP1000. These compact joysticks are different in that they have a very interesting ‘slide’ feeling.

These are massive single pole - double throw (SPDT) sealed relays.

OBDII is an on board diagnostics standard that is used on a large variety of cars. OBD-II provides access to numerous data from the engine control unit (ECU) and offers a valuable source of information when troubleshooting problems inside a vehicle. If you’re not sure if your car works with OBDII you can look under your dash, the connector is generally located below your dash on the driver side. This is great if you want to try to build your own diagnostic reader.

This is a 3-terminal microswitch two pack, each equipped with a 20mm offset lever actuator. These switches have a great ‘clicky’ sound to them with a nice tactile feel and are perfect when used for a slider, 3D printer, or robot project. Each microswitch is rated for 5A at 250VAC.

This is a simple cable that adapts from a USB port to a 5.5x2.1mm barrel connector, center positive.

These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000Ohms allowing the user to very accurately calculate the relative position on the strip.

Beyond the clear plastic, this is really just a regular, solderless breadboard. It has 2 power buses, 30 columns, and 10 rows - a total of 400 tie in points. All pins are spaced by a standard 0.1". The two sets of five rows are separated by about 0.3", perfect for straddling a DIP package over. The board accepts wire sizes in the range of 29-20AWG.
