有两组机械装置通过和乐谱有相同频率的步进电机来产生声音。另外一台机（Jacob’s Ladder)器采用继电器控制一台12000V的变压器，其他三台机器通过金氧半场效晶体管(Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET)连接电磁阀和汽车闭门器。除了Jacob’s Ladder，所有装置由计算机电源供电。机器的主体结构由透明的有机玻璃板构成采用铝制配件连接，所有有机玻璃部件均由镭射切割机制作。
Created by Neil Mendoza, The Electric Knife Orchestra consists of sixteen knives and one meat cleaver (all purchased from the $0.99 store) that have been brought to life to perform the Bee Gees’ 1977 hit Stayin’ Alive. The orchestra consists of six musical machines and all of the sound is created through the operation of these machines.
All of the instruments are controlled using one Arduino running firmware based on code available online. The music was arranged in Logic, output using a USB to MIDI cable and then read by the Arduino using the MIDI circuit.
There are two machines that create sound by stepping stepper motors at the same frequency as musical notes. The Jacob’s Ladder uses a relay to control a 12,000V neon sign transformer and the three other machines work using MOSFETs connected to solenoids and car door lock actuators. Apart from the Jacob’s Ladder, the whole installation is powered using a computer PSU. The machines themselves are mainly constructed of transparent acrylic and were prototyped using aluminium extrusion and then designed in a vector graphics program and laser cut.
