About Mumbo Jumbo
Oli, known as Mumbo Jumbo, is a British Minecraft creator famous for redstone, the in-game wiring system players use to build working machines. He is also known for his time on Hermitcraft and his famous moustache.
Video one
His earliest uploads are no longer public. The oldest still on the channel is "Supercharged 4x4 Vault Door [Opens in under a second!]" from June 2013, a redstone build that shows what the channel is about.
The breakthrough
Mumbo's clear, funny redstone tutorials made complicated Minecraft engineering approachable. Joining the Hermitcraft server brought him to a much larger audience.
Today
He still makes redstone builds and Hermitcraft episodes, and aims to help viewers build things "you can show off to your friends".
