If you don’t happen to have a traditional stone-floored domed clay oven on hand, it can be surprisingly challenging to make a pizza that’s truly excellent. Your domestic oven does a reasonable job, but doesn’t really get hot enough. Even a specialist pizza oven such as [Yvo de Haas]’ Ooni doesn’t quite do the best possible, so he’s upgraded it with the SpinMeister — a system for precise timing of the heat, and controlled rotation of the cooking stone for an even result.

The spinning part is handled by a stepper motor, driving a hex shaft attached to the bottom of the stone through a chuck. The rotating bearing itself is from an aftermarket stone rotator kit. The controller meanwhile is a smart 3D printed unit with a vacuum-fluorescent display module, powered from an Arduino Nano. There’s a motor controller to handle driving the stepper, and an MP3 module for audible warning. It’s all powered from a USB-C powerbank, for true portability. He’s produced a video showing it cooking a rather tasty-looking flatbread, which we’ve placed below. Now for some unaccountable reason, we want pizza.

If you recognize [Yvo]’s name, then perhaps it’s because he’s appeared on these pages a few times. Whether it’s a tentacle robot or something genuinely different in 3D printing, his work never ceases to be interesting.
