Look Mum No Computer

Sam James Bartle (born 3 February 1989), known by the stage names Sam Battle and Look Mum No Computer, is an English musician, YouTuber, electronics enthusiast, and composer. He posts videos about making pro audio equipment and synthesisers, as well as original music.

Bartle builds unusual and eccentric electronic musical devices made from vintage technology, such devices as a Furby organ, a synthesiser fused with a classic Raleigh Chopper bicycle, and a Game Boy Triple Oscillator synthesiser. Battle runs This Museum Is (Not) Obsolete, a museum in Ramsgate, Kent, which showcases vintage analogue devices repurposed for humorous uses. He represented the United Kingdom in the Eurovision Song Contest 2026 with the song "Eins, Zwei, Drei" and finished in last place with 1 point.
