This was a commission to control the power sequencing of Arcade cabinets (or any device really) to allow automatic powerup and powerdown of the units in a controlled way.
Previously the owner used a master switch and turned on the devices simultaneously. This however caused two issues: 1) A large power surge that technically exceeded the rating of the connecting wiring and 2) Interference between the machines (classics!) owing to their differing rates of degauss.
The Activator solved both by switching on each unit in a controlled manner with several seconds pause in between. On power-down the cycle is reversed. Very pleasing as an effect as well!
