Much more information and complete instructions are on the Wiki.
The most current design is the MK-1104 with its 3D printed enclosure. An older design, from 2017, is the MK-1101 and MK-1102 which fit into aluminum enclosures manufactured by Bud. All the devices are functionally identical and nearly so with the much older MK-1100 that was manufactured by HAL.
The TextFixture and the Arduino sketch are shared among all the designs.
