DVM (digital volt meter) and its probes.

nScope unit on Protoboard.   Note that the the outer rails are ground despite being painted red and blue.   The inner rails are -5V (left, blue) and +5V (right, red). Labels for the rails are printed at the edge of the nScope, and there are lights to correspond as well (green for ground, blue for -5V, red for +5V)

Transistors, two types: NPN and PNP.

Visible light phototransistor, and IR-only phototransistor


Integrated circuits, IC's, "chips"
