Continuity Tester
thingiverse
To solve the issue of unavailability of AA battery holders at the "Shack," I made a DIY single AA holder featuring a small bulb receptacle and side channels for wire management. Use it for electricity conduction experiments, after adding a 1.5v bulb (RS 272-1139) and connecting wires to battery contacts and the bulb ends. Alligator clips can be added optionally for enhanced functionality.
