Here's a way to safely use your BS2 STAMP to control holiday light displays. Note there is no dangerous 120 vac wiring required. The PowerSwitchTails come prewired with standard 120 vac power plugs and receptacles that connect to regular household devices including Christmas light strings. Each PowerSwitchTail is connected to the STAMP controller by a single pair of wires carrying 5 volts dc. Here I am using a CAT5 cable that I had on hand to drive 4 circuits. The switch on the power strip is a master on/off switch.
