A self-taught multi-media artist living in Brighton since 1985, Helliwell has amassed a large body of work through a synthesis of analogue and digital equipment, using various hands-on techniques to realise his ideas. His approach embraces both antiquated and contemporary technology, and his many years of audio-visual experience incorporates music, film, animation, analogue electronics, instrument building, collage, installations, light show projection, live performance, writing and film programming.
He has made over 100 short experimental films screened worldwide, all featuring electronic music soundtracks, and years of experimentation with building and modifying 9v circuitry, has led to the design and construction of his unique series of Hellisizer synths and Hellitron tone generators, using 'intuitive electronics' and 'creative soldering' techniques.
His first feature length documentary film, Practical Electronica, looking at FC Judd and early British tape recording was completed in 2011, and for five years he has been researching and writing Tape Leaders, an A-Z book on early British electronic music composers.
