Programmable disco lights array (1984)

Elektor in 1984 saw a niche for a disco lights controller that was unusual and novel in not being limited to dull, fixed light patterns. In other words, the keen user of the ambitious project printed in the February 1984 issue of Elektor could really make the crowd go bezerk with light effects far more ‘groovy’ than those of a simple light organ, a couple of coloured floodlights and of course the corny globes on the ceiling. The Elektor project offered no fewer than 32 programs in memory to control up to 30 lights individually. The associated triac driver unit was a separate unit described in the March 1984 issue.
