Heller

Heller was an individual who owned a suit of Cresh Luck armor. Heller modified the default alarm system of the armor using the "tingler" of a blaster pistol—commonly used to warn of an almost empty magazine—. Instead of warning of proximity attacks through a noise, the armor did so with a subtle "tingle".

Reading about the problems of the Cresh Luck armor's noise on a post by Jatras in Gundark's Gear Datalog, Heller replied posting his suggestion.
