Sam Battle (born 1988 or 1989), better known online as Look Mum No Computer (stylised in all caps), is an English musician, YouTuber, electronics enthusiast, and composer who posts videos about making pro audio gear and synthesizers, as well as original music tracks.
He is known for making and playing unusual and eccentric electronic musical devices made from vintage technology; notably such devices as a Furby organ, a synthesizer fused with a classic Raleigh Chopper bicycle, and a Game Boy Triple Oscillator synthesizer. Battle runs This Museum Is Not Obsolete, a museum in Ramsgate, Kent which showcases vintage analogue devices repurposed for humorous uses. He is set to represent the United Kingdom in the Eurovision Song Contest 2026 with the song "Eins, Zwei, Drei".
