Since the start of the 1990s Ian has been developing his own 'intuitive electronics' method via 'creative soldering', and has built a whole series of Hellitron tone generators, which he uses to realise his film soundtracks. He has also put together more sophisticated synth units - the Hellisizer series - which includes the 1000, 2000, 3000, 4000, Compact and Junior models. The performance version Hellisizer
2000 - designed from scratch and 8 months in construction, made its live debut in September 2007, and formed part of Ian's Music, Movies & Machines exhibition and 2008 film.
More recently he has designed and built the Hellicam - a simple video camera, especially useful for creating video feedback.
The Percussimate is a rhythm generator featuring drum machine, electronic percussion and echo unit. The Megatherm is an opto-acoustic instrument, and has a specially made super 8 film projected onto it, for which it automatically plays the electronic soundtrack by reacting to the light content in the film.
