Whilst at the Open Hardware Summit 2025 in Edinburgh, UK, we met Gerrit, who spoke about growing food with electricity while representing AMYBO, an online community dedicated to developing sustainable protein food sources.



The talk is excellent, and it’s available on YouTube. In it, you can see and hear a lot of information about the Pioreactor: a tiny automated bioreactor that allows complex science to take place on your desk. It’s powered by a Raspberry Pi, and is the go-to tool for many professional, amateur, and hobbyist biologists and chemists; it’s also used by a fascinating research community called AMYBO.

What is a bioreactor?What is a bioreactor?

A bioreactor is a vessel that provides an optimised environment for growing cells, microorganisms, and microbial cultures. In its simplest form, it could just be a jar, but the term ‘bioreactor’ commonly describes more complex setups in which the environment can be controlled and automated. Bioreactors are typically used in the development of pharmaceuticals, as well as in the food sciences, medical sciences, and many other chemistry- and biology-adjacent sectors.
