We have a finite number of electronics modules for use in the lab. However, researchers tend to find a near infinite number of ways to use these electronics. Thus, there is always a high demand for the electronics modules. If you are not currently using a piece of electronics at your experiment, it is considered available for use by other lab personnel. If you take a piece of electronics from someone else's experiment, leave a note so that they will know where to find the electronics when they wish to continue their experiment.
Hand tools are another frequently used item around the lab.
Each experimental group has its own basic set of hand tools. However, there will be times when a more specialized tool is needed. When you have a malfunction, take the equipment out of service so that it may be repaired. If you are unable to make the needed repairs, take the equipment to the appropriate repair facility. Broken electronics are to be placed in the Broken Electronics box in the control room along with a note clearly explaining the problem.
