This repo contains instructions for assembling, testing, and operating an open-reel 1/2" magnetic videotape cleaner. When used in conjunction with other remediation treatments like incubation, tape cleaning assists in minimizing the effects of tape degradation such as binder hydrolysis ("sticky shed syndrome") during the playback/reformatting process.
Controlled by an Arduino Uno microcontroller and integrated motor shield, the machine consists of a dual-motor spindle system that moves tape through two Pellon cleaning stations. Tape speed and tension are monitored through feedback from optical encoders attached to each motor's shaft. Each Pellon cleaning station incrementally advances fabric past several contact points.
