Daniele Procida (He/him)


BrachioGraph is the world's cheapest, simplest pen-plotter (€12.50 for all parts, including a Raspberry Pi). It's powered by Python and constructed from household items, assembled using basic tools and glue.

In this workshop, we'll build the machine, install the software to run it - and get plotting.

All the instructions and software are detailed at, and that's what we'll follow in the workshop.
